Code Downgrade from 7.4 to 7.0
Working on a project consolidating all controllers to a single 8500 controller with a standby. Moved an AP over to test the process and everything worked fine. Took a little longer than I thought it would, but given the design with new flexconnect abilities, the creation of AP groups well you know.
I get the AP over and one of my ssids doesnt work because the key is different, so gotta move the AP back over to resolve production issues.
Are there any none issues when downgrading from 7.4 to 7.0?
Thanks in advance.
In my experince is when you configure any of the new features in the advance code (7.4 for exmaple) and then you downgrade you lose those configs. On a normal controller I havent had any issues.

Hi, I want to downgrade from OSX LEOPARD to OSX TIGER but I have a few questions regarding this. My iMac is originally from Sep 2007 it came preloaded with tiger. I have original install (2) tiger discs version 10.4.10. I want to know if it is safe and what are the necessary steps to do so. Also by downgrading im wondering if a lot of apps nowadays support tiger for example I have photoshop version 5 and 4 these are very important to me. One last question does anyone know of any reliable virus protection for mac that doesnt slow down your computer? because I have read that a lot of them do so. If anyone can help me I would greatly appreciate it! Here are the specs for my iMac

800 MHzMost of the time a perception of general slow performance is the result of installing third party junk alleged to speed up, "clean" or "optimize" your Mac, or to look for viruses that don't exist. Ideally you would know what you installed so you can uninstall it, but if you don't know or aren't sure there are techniques such as Safe Mode and creating a temporary user account to confirm that suspicion.
If you open Activity Monitor it may show a process, or processes, that occupy a lot of your system's time.
Slowness confined solely to web browser activity is often the result of an inexorable progress toward websites that demand ever more processor-intensive tasks. If your slow performance is strictly limited to web browsing, you might try disabling Flash by either uninstalling it, or use utilities such as ClickToFlash that allow you to control what Flash content gets loaded. Flash in itself is not inherently evil, but there is nothing to stop websites or the advertisers who pay for them from writing horrible Flash code that can do everything from hogging 100% of your CPU's time to causing random crashes. You can watch Activity Monitor as in the above to correlate these troublesome web pages with performance degradation.
You are correct; if your computer shipped with Tiger you may certainly revert to it. I forgot that Tiger was shipping on new Macs as recently as five years ago. To downgrade it would be necessary to completely erase your hard disk and boot with the Tiger installation DVD, followed by installing it anew. Such drastic measures are not necessary and you are unlikely to be satisfied with the results anyway.
Assuming your system is free of third party parasitic junk attached to OS X in an ill-conceived attempt to improve upon it, that your hard disk drive is sound and the boot volume has enough free space to work with, by far the best performance-enhancing improvement would be to add more memory. Buy as much as your computer can use and that you can afford. 2 GB is not that much any more.

How to downgrade from Internet explorer 11 to internet explorer 10 on windows server 2008 R2
Hi,
Can someone please let me know how I can downgrade from IE11 to IE10 in my windows server 2008 R2. When I go to control Panel -> Programs -> features and I don't see any program name with internet explorer in that list. Also, when I go to on
'View installed updates', I don't see any update related to IE 11 installed. And, when I click on 'Turn windows feature on or off', it takes me to Server Manager and in there I dont find any feature related to IE.
Any help is much appreciated.

Downgrading from JDK 1.5.x to JDK 1.4.x
Hi there,
I hope someone helps me with an issue:
I developed a web app using JDev 10.1.3.3 using the JDK 1.5 included with JDev.
As we are now faced with the fact that this app has to run on an OAS 10.1.2, which to my knowledge uses JDK 1.4.x I have to downgrade from JDK1.5.x->1.4.x.
The technologies that I used are Toplink, EJB 3.0 Session Bean and ADF Faces for the UI layer.
I already downloaded and installed JDK 1.4.2_15 from Sun and changed the default JDK from 1.5.x in JDeveloper to use 1.4.2_15. When I recompiled my Model Project, as excected, I got the following compilation errors on my Bean Class java source file:
Error(29,1): errorIllegalCharacter
Error(29,2): 'class', 'interface', or 'enum' expected
on the same line where I had the EJB 3.0 annotation as follows:
@Stateless(name = "NordPublicFacade")
and also on my Local Interface source:
Error(22,1): errorIllegalCharacter
Error(22,2): 'class', 'interface', or 'enum' expected
for the line:
@Local
OK, I know that these annotations/injections(or whatever they're called) are new features of EJB 3.0 and can only be used with JDK 1.5.
I also have red underlines in some facade methods where generics are used for Toplink Named Queries (please remember this is generated code) so for example:
List<CompanyStructure> findAllCompanyStructure();
On my ViewController project (the UI project) I get the following errors:
refresh = false;
Error(37,17): operator = not applicable to class java.lang.Boolean and boolean
JSFUtils.setManagedBeanValue(ctx,"userState.refresh",true);
Error(92,7): method setManagedBeanValue(javax.faces.context.FacesContext, java.lang.String, boolean) not found in class NordMaintApp.view.util.JSFUtils
My questions
1) What's the best way to go about downgrading?
a) Should I create a new EJB 2.x Session Bean or should I use the Java Service Facade (which I hope creates a POJO and therefore is EJB version independant or not?)
b) Is it necessary to do anything special to the Toplink classes?
2) What are the errors that I get in my ViewController project ?
Thanks In Advance
G.P.Hi again Shay and THANK YOU!
We simply downloaded OC4J 10.1.3 & installed it (all we had to do is simply unzip it) in a separate directory on its own, on the SAME Server as OAS (10.1.2.02 EE, which includes Discoverer and Portal) AND IT WORKED !
We're now back on using JD 10.1.3 with all its new features etc etc. We even downloaded JDK1.5 and got OC4J working with this JDK WITHOUT, of course, affecting our OAS 10.1.2 installation which works with JDK1.4.2. That woudn't have been possible without your feedback.
It's just that looking at that reference you gave me, I thought that I would have to create a separate instance on the OAS 10.1.2 installation and install 10.1.3 on that one. But eventually it was so much simpler than that. And the memory overhead of OC4J is not that much.
I could create a simple ADF JSF page which just displays data from a table and it's OK!
I could deploy it just fine, though I found out that I have to deploy the ADF Runtimes first; OC4J doesn't come with them. Other than that, it was just fine!
As I said, I'm now using ADF JSF pages for my front-end and ADF BC for my back end; it's so much easier than using Toplink directly.
Only one problem left though (sorry to bother you like that):
In one of the previous emails you mentioned it might be better to use Webcenter for ADF Faces. Unfortunately we cannot go with this option I'm afraid, because we already have an existing portal running on the Oracle Portal that's already included with our OAS 10.1.2.02. I assume that the Oracle Portal's version is also 10.1.2.02. Can I deploy ADF JSF faces as a portlet on this one ? I realise that JDev 10.1.3 comes with some wizards to do this and it seems that I have 2 options: Oracle PDK-Java Portlets or JSR-168 based portlets. I just want whichever one will allow me to have my ADF JSF pages deployed as Portlets on OP 10.1.2.02, so that it can be integrated into any one of the exisiting Portal pages that a colleague of mine already developed (and are waiting for my pages to finish, which currently, when called from a link inside a Portal page displays it in a new page and the user can get back to the Portal page by clicking on the browser's back button). I realise that If I have the JSF page as a portlet, it will then be possible to be integrated into an existing page, that is, have my page to occupy it's own region in a Portal's page.
Once again, Thanks for your help and Thanks In Advance.

Is it possible to downgrade from iTunes 11 back to 10.7
Hi
- Really not linking iTunes 11 , is it possible to downgrade, any answer would be extremly helpful!
Thanks
- Tom=Downgrading from iTunes 11 to iTunes 10.7=
Try activating the sidebar, menu bar, and status bar and see if this is close enough to the previous version to make you content. It is easier than downgrading and eventually you will be forced to run a newer iTunes unless you have an endless supply of the model computer you currently own.
You may be able to go back with Time Machine but this may involve restoring other items too (https://discussions.apple.com/message/20441404). Alternatively:
Back up your computer first, in case the unexpected happens.
Here's a step-by-step method and you may find it easier to follow than alternative methods I have posted below.
Downgrade iTunes 11 to iTunes 10.7 - http://www.emacconsulting.com/apple/itunes/downgrade-itunes-11-to-itunes-10-7/
If the above does not work, or you want to do it without Pacifist, or you want to know what is actually going on when downgrading, or you encounter error messages, here's more details:
Quit iTunes.
Get iTunes 10.7 from http://support.apple.com/kb/DL1576 or the direct download link at: http://appldnld.apple.com/iTunes10/041-7195.20120912.d3uzQ/iTunes10.7.dmg
Do a few preparatory steps by making sure all iTunes components are not running and cleaning old files. See https://discussions.apple.com/message/20475394. Do steps 3 and 4. Steps 6-8 may be also useful but I don't know if they are essential. Some of the other steps are not necessary, duplicate steps listed later in my post or are perhaps even unhelpful in the process.
Replace the iTunes 11 application with iTunes 10.7. Simply dragging the application to the trash may not work. Lion (OSX 10.7) and newer systems have iTunes integrated into the operating system and deleting is a bit more involved. Two ways to do this are:
1. (Easier) Use the shareware Pacifist utility (http://www.charlessoft.com/) to install iTunes 10.7 including all associated system files. Details at http://forums.macrumors.com/showpost.php?p=16400819&postcount=6
2. (More work) Check this reference on how to delete the iTunes application itself:
Delete iTunes in Mac OS X 10.7 Lion - http://osxdaily.com/2011/09/13/delete-itunes-in-mac-os-x-10-7-lion/
After deleting the application there may be other files that need downgrading too. See the note about error -42408 at the end of this post. You may want to tuck these away somewhere safe until you have completed the installation of iTunes 10.7. I have not tested this but ideally if newer versions are not found then the installer will put in the old versions. This may include these files in /System/Library/PrivateFrameworks/ which apparently get updated by iTunes 11:
AirTrafficHost.framework
CoreFP.framework
DeviceLink.framework
iTunesAccess.framework
MobileDevice.framework
After doing one of the two procedures above you will have to rescue the most recent old iTunes library from your iTunes > Previous Libraries folder. Rename it "iTunes Library.itl" and replace the existing one in the iTunes folder. A newer version of iTunes irreversibly updates your library file so you have to replace it with the old one or you will get an error message. Note, this will revert your library to the version at the time of the upgrade and you will have to update any changes made since. See:
https://discussions.apple.com/message/20401436 - turingtest2 11/2012 post on rebuilding empty/corrupt library from previous iTunes library file after upgrade/crash.
iTunes: How to re-create your iTunes library and playlists - http://support.apple.com/kb/ht1451
Other issues:
- https://discussions.apple.com/message/20432309 - solution to mobile devices saying they need to be restored after downgrading
- If you encounter error -42408:
iTunes: Advanced iTunes Store troubleshooting - http://support.apple.com/kb/TS3297 > Specific Conditions and Alert Messages: (Mac OS X / Windows) - including specific error codes.
Alternatively, check https://discussions.apple.com/message/20441424 which requires you have a Time Machine backup (though possibly if you remove the newer version of these files old ones may be installed with the iTunes 10.7 installer - untested). A variant of this is at: https://discussions.apple.com/message/20448184

Why is the downgrade from ios5 to ios4 forbidden by itunes apple ?
Problems of downgrade from newest to oldest as ios5 to ios4 forbidden :(
It is forbidden by Apple to Downgrade iPhone 4. To Restore an iPhone 4 the iPhone must receive a special code (signing) specific to the iPhone to Restore, only Apple has the secret Algorithm. Apple only supplies the code for the Current Firmware. So Apple does not allow downgrade of iPhone 4. In addition iTunes is programmed to halt the Restore Process if it detects an attempt to downgrade the Firmware of iPhone 4. So in summary, Apple forbids the downgrade of iPhone 4.
Even the Head Apple Genius could not downgrade any new iPhone 4, or any new iPhone 3GS, or any new iPhone 4S. Because Apple forbids it. -

DavidHi David,
Is NX-OS 6.2(1) the correct version? The reason I ask this is because as far as I'm aware this release is not officially available at this time. I've just checked again and there are no release notes or download option for NX-OS 6.2 on CCO currently.
Assuming you've not made a typo in the release you're trying to downgrade from, the best advice I can offer at this point would be to attempt a multistep downgrade to either NX-OS 6.1 or 6.0 first. It may be that a single step downgrade from NX-OS 6.2 to 5.2 is not a supported option, but as there's no documentation for NX-OS 6.2 at this time we don't know.
At least if you can get to either a 6.1 or 6.0 release, then when you attempt the downgrade to NX-OS 5.2 it'll be one shown as supported.

Why Apple make so bad thinks.
Here are the thoughts: IOS Security
System Software Authorization
Apple regularly releases software updates to address emerging security concerns and also provide new features; these updates are typically provided for all supported devices simultaneously. Users receive iOS update notifications on the device and through iTunes, and updates are delivered wirelessly, encouraging rapid adoption
of the latest security fixes.
The startup process described above helps ensure that only Apple-signed code
can be installed on a device. To prevent devices from being downgraded to older versions that lack the latest security updates, iOS uses a process called System Software Authorization. If downgrades were possible, an attacker who gains possession of a device could install an older version of iOS and exploit a vulnerability that’s been fixed in the newer version. -

Windows XP Pro SP2 cd-rom after downgrading from Vista
Hi everybody.
I successfully downgraded my T61p from Vista to XP Pro SP2 using the downgrade cd-roms send by Lenovo.
Everything seems to work well. I downloaded all drivers. No problem.
But I recently installed a rather old software that I frequently used on my old A31p. This software (a Microsoft program !) has automatically modified some files from XP Pro without any autorization.
Once it was done, I was asked by the system to insert the original Windows XP Pro SP2 cd-rom to repair this modification.
Of course, the (Vista to XP) downgrade cd-rom set was not recognized by the Thinkpad as the original XP set.
An original cd-rom which I finally don't have !
I tried with an original XP Pro SP2 cd-rom bought a few years ago for my A31p. Unsuccessful.
Where could I find the XP Pro SP2 cd-rom corresponding to the downgraded system ?
Thanks for your help and suggestions.
Regards.

Thinkpad A31p - T42p - T61p - TP TabletJames,
thanks for your answer.
But I wrote on my first post "I tried with an original XP Pro SP2 cd-rom bought a few years ago for my A31p. Unsuccessful."
Thus, I don't see any difference between an original Microsoft Windows XP2 Pro SP2 version cd-rom and one created by burning a downloaded version of the OS. An original was not recognized, what would a copy do ?
If possible, it might be probably better to create an XP Pro SP2 cd-rom from the "Rescue and Recovery" files which were reinstalled when downgrading from Vista to XP. (I hate the word "downgrade" : while I was doing it, I had the feeling I was upgrading my Thinkpad !)
I have been using for several years (and still use) an A31p (Since 2002, 8 to 10 hours a day) and a T42p. IMHO, the T61p is the same category of "great" notebooks. Thinkpads are really the best notebooks I have ever used. I noted no significant difference between IBM and Lenovo Thinkpads.

I am trying to use the relatively new Code First from Database with the newest EF (6.x) and on an Oracle database (11g, but I have installed the newest ODTwithODAC). First of all, it works fine as long as the connection string is inside the App.Config file. But when I try to build it dynamically in the C# code (or rather, statically at the moment) it fails. I have it working with a dynamically built connection string when doing Model from Database though, so I'm at a loss right now.
First, I have created a second constructor for the context class that takes a string and does base(connectionString). Then I build the connection string via
OracleConnectionStringBuilder oracleBuilder = new OracleConnectionStringBuilder();
oracleBuilder.DataSource = "TEST.BLA.COM";
oracleBuilder.UserID = "ABC";
oracleBuilder.Password = "abc";
oracleBuilder.PersistSecurityInfo = true;
string connection = oracleBuilder.ToStrin();
Now trying to open an EntityConnection by giving to it this provider-specific connection string (or even the static one from the App.Config) doesn't work; I get "keyword not supported: user id"). Trying it by creating a context and giving this connection string doesn't work either. I'm pretty sure that this is because I didn't specify the provider to use; after all, it should use the Oracle.ManagedDataAccess.Client provider and not an SQL Server based one.
I then tried to get around this by using an EntityConnectionStringBuilder on top and specifying the provider keyword there, but then I get "keyword not supported: provider" when using it in the context constructor, and "the 'metadata' keyword is always required" when using it with the EntityConnection constructor.
As I said above: I bet it's the provider that I have to specify somehow, but I don't know how. The code that does work is the following:
using (var context = new Model())
context.Database.Connection.Open();
context.Database.Connection.Close();
When I read context.Database.Connection.ConnectionString, it is exactly the provider-specific connection string I created above, but I don't know where to specify the provider again. Do you know of any way to do this? Certainly there must be one.
PS: I have also posted this question on http://stackoverflow.com/questions/27979454/ef-code-first-from-database-with-managed-oracle-data-access-dynamic-connection because it is quite urgent and I'd like to use Code First from Database. Otherwise I'd have to go "back" to using Model from Database again, which is not ideal because we have updatable views where the .edmx-file has to be edited after every reload of the model, while with Code First from DB inserting into the view automatically works.I am trying to use the relatively new Code First from Database with the newest EF (6.x) and on an Oracle database (11g, but I have installed the newest ODTwithODAC).

I have it working with a dynamically built connection string when doing Model from Database though, so I'm at a loss right now.
First, I have created a second constructor for the context class that takes a string and does base(connectionString). Then I build the connection string via
OracleConnectionStringBuilder oracleBuilder = new OracleConnectionStringBuilder();
oracleBuilder.DataSource = "TEST.BLA.COM";
oracleBuilder.UserID = "ABC";
oracleBuilder.Password = "abc";
oracleBuilder.PersistSecurityInfo = true;
string connection = oracleBuilder.ToStrin();
Now trying to open an EntityConnection by giving to it this provider-specific connection string (or even the static one from the App.Config) doesn't work; I get "keyword not supported: user id"). Trying it by creating a context and giving this connection string doesn't work either. I'm pretty sure that this is because I didn't specify the provider to use; after all, it should use the Oracle.ManagedDataAccess.Client provider and not an SQL Server based one.
I then tried to get around this by using an EntityConnectionStringBuilder on top and specifying the provider keyword there, but then I get "keyword not supported: provider" when using it in the context constructor, and "the 'metadata' keyword is always required" when using it with the EntityConnection constructor.
As I said above: I bet it's the provider that I have to specify somehow, but I don't know how. The code that does work is the following:
using (var context = new Model())
context.Database.Connection.Open();
context.Database.Connection.Close();
When I read context.Database.Connection.ConnectionString, it is exactly the provider-specific connection string I created above, but I don't know where to specify the provider again. Do you know of any way to do this? Certainly there must be one.
PS: I have also posted this question on http://stackoverflow.com/questions/27979454/ef-code-first-from-database-with-managed-oracle-data-access-dynamic-connection because it is quite urgent and I'd like to use Code First from Database. Otherwise I'd have to go "back" to using Model from Database again, which is not ideal because we have updatable views where the .edmx-file has to be edited after every reload of the model, while with Code First from DB inserting into the view automatically works. -
How Do I Downgrade From Windows Vista To XP On A 3000 N100 Series Notebook?
Hello. Here is the problem. I have Windows Vista Pre-loaded on my 3000 N100 Notebook, absolutely dislike this operating system and want to erase and load Windows XP. From reading other forum messages I have learned several things.
1) The install disk On Windows XP Home & Professional will not recognize Sata Hard Drives, when it reaches the point of loading where it looks for the hard drive it "BOMBS OUT" with error messages.
Several options are open .............
1) Log into the BIOS, locate the SATA option, and change to compatibility mode.
2) Have a USB external floppy connected with a Sata Driver on it and when installing Windows XP press the "F6" button when Windows asks for any external drivers you want to load.
Here is the problem with the 3000 N100 Notebook series..........
1)There is "NO SATA OPTION" in the BIOS of the 3000 N100 series notebooks to choose. In this model Lenovo stripped the BIOS down to the bare essentials.......and I Do Mean.... "BARE". The latest BIOS upgrade also has no Sata option. Why they did not offer at least this choice of downgrading to XP is beyond me. LENOVO..... I'm not impressed with your notebook. As usual.... Microsoft has all vendors jumping to their tune..... Nothing but "VISTA" at this point in time. What if you hate it??????
2) I have hunted all over the Lenovo Web Site for a "SATA DRIVER" that would work with a 3000 N100 Notebook, no such critter exists. LENOVO..... Couldn't you have at least offered this???? I'M NOT IMPRESSED.
Has anyone been able to downgrade to Windows XP successfully on a 3000 N100 Series Notebook??? How Did You Do It?? Has Anyone Located A "SATA DRIVER" That Works??? IF So, Please Explain To Me Step-By-Step How I Can Get Rid of Vista and Load XP.
Help........Help.......Help........Help......Help!!!!!!!!!!!
RegardsHello Himleung. Thank you for answering this message. Where did you find a "Sata Hard Drive Driver" that works?? Perhaps you could pass that along to this message forum in case someone else that has a 3000 N100 (may also work with the N200 series) Notebook wants to downgrade from Vista to Windows XP.
This is what baffles me to no end. The Lenovo web site has every driver you need to load Windows XP on the notebook.....**EXCEPT**..... the Sata HD Driver......**OR**...... the ability in BIOS to change to "compatability mode". Duh!!!..... whats wrong with this story. I have never seen such a weak BIOS as the one in the 3000 N100. If I had known this I probably would have gone to another brand. They should have advertised this notebook as...... "Non-Geek Compatible".
Not knowing exactly how you could forward the driver to me I did the following....... I created a new Web email location that you could use to send the driver as an email attachment. The address is....... [email protected] This address will exist just long enough to obtain the driver..... and then......"Hasta-La-Vista" baby......end of story......as I do not want to be bombarded with ads, trash, or perhaps a virus of some sort..... although.....I'm SURE we have GREAT PEOPLE on this message center.
I'm not familiar with the "NLITE" program you mentioned. Again....perhaps you could mention where I can get it and what I need to do to set the program up to run the driver.
Thanks again, Himleung.

I found this piece of information: http://osxdaily.com/2012/06/18/downgrade-ios-6-beta-to-ios-5/ Yes, it's about downgrading from iOS 6 beta, not iOS 6, but the way to downgrade to a previous version of iOS is basically the same.
I have an iPhone 4 running iOS 5.1.1 and an iPod touch 4 running iOS 5.1.1 as well. None of them is 'jailbroken'. I upgraded my iPod touch to iOS 6 for exploring it a bit more and reverted back to iOS 5.1.1. How? I did it the way stated by the website I mentioned above: just by Option-Clicking the 'Restore' button on iTunes and select the iOS 5.1.1 software. No need to enter recovery mode or DFU mode whatsoever.
In fact, Apple doesn't allow users to downgrade to a previous version of iOS: 'Downgrading to a previous version of iOS is not supported.' (http://support.apple.com/kb/TS3694) The reason why I could downgrade from iOS 6 to iOS 5.1.1 may be, as the above website said, 'Typically you can’t downgrade iOS versions so easily, but because Apple is still signing iOS 5.1.1 this allows downgrading to commence with minimal effort.'
I was wondering whether I could revert all the way from iOS 5.1.1 to iOS 4.1 (the version that was shipped along with the launch of the iPod touch 4 in September 2010). (for experimental purposes)
I downloaded the iOS 4.1 (a list of iOS software: http://osxdaily.com/2010/10/30/download-ipod-touch-firmware-ipsw/) and tried Option-Clicking when restoring this iOS 4.1 — no luck. iTunes said 'This device is not eligible for the requested build'. And I did a bit of research and found that there are ways to downgrade from iOS 5.1.1 to iOS 4.1, but it seems you have to jailbreak the device, which is complicated and I don't want to do.
So, is there a way to downgrade from iOS 5.1.1 to iOS 4.1 without any unauthorised modifications (e.g. jailbreaking)? Thanks in advance.No, downgrading from any version of iOS to an earlier version is not supported.
