Firmware downgrade from 1.2.1 to 1.1.0

Per the release notes
Because of a change to the bootloader in firmware version 1.2.1(004), downgrading to earlier versions is not possible.
However I took one that was on 1.2.1 and pointed it at my 1.1.0 firmware and it looks like it worked. The device shows 1.1.0 now.
Are there any expexted issues related to running on this. The devices are registered and I have not had any issues in my lab.

Hello Sage Major,
Previous "beta" versions of 1.2.x firmware allowed downgrading to v1.1.0(011). However, the official release of v1.2.1(004) will not permit downgrading back to v1.1.0(011).
v1.2.1(004) is a much better firmware version and addresses many issues that were present in v1.1.0(011). The SPA1x2 ATA will still perform but downgrading back to v1.1.0(011) would revert its capabilities backwards and eliminate the improvements developed in the latest release.

How can i Downgrade from iOS 6 beta Firmware to iOS 5.1.1 iPhone 4 A4 . After I've upgraded my machine batteries run out very quickly, so I want to Downgrade, I don't have shsh blobs

How can i Downgrade from iOS 6 beta Firmware to iOS 5.1.1 iPhone 4 A4 . After I've upgraded my machine batteries run out very quickly, so I want to Downgrade, I don't have shsh blobs

There is no reason to be running beta software, I doubt it will even still run as iOS 6 has been officially released. Or were you simply trying to be funny?
Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.

Legitimately downgrade from 2.2 firmware, is this possible?

Hi,
I've done some quick searching, probably not as much as I could have, but I'm agitated and couldn't find any satisfactory answers.
So I downloaded and installed the 2.2 firmware update and soon found out that apps like Mind Beats, White Noise and Asleep no longer produce sound when the screen goes to sleep. But as soon as you press the home button and it brings up the locked screen, the sound comes on again. This bug is really annoying me.
So my question is this, is it possible to legitimately downgrade from the 2.2 to the 2.1 firmware? I do not want to join the dark side as it were, but I feel that this bug justifies my doing so, if the problem can not be fixed.
Any help would be much appreciated.
Thanks.

Hello and Welcome to Apple Discussions.
Depends if you have overwritten the backup since upgrading. Try going to iTunes > Preferences... > Devices > Device Backups and revert to the last good one. Hopefully it's a 2.1 backup. Obviously any recently written Notes etc may be lost.

Downgrade from Leopard to Tiger after Built-In Keyboard Firmware Update?

Can I downgrade from Leopard to Tiger after having applied the Built-In Keyboard Firmware Update 1.0? This firmware update requires OS 10.5.2 or higher to be installed. Now that it is installed can I downgrade back to Tiger (10.4.11)?
I have a MacBook Pro 17 (late 2006). It ran perfect except for the occasional ignored first key press problem that these MacBook's have. In late December I upgraded to Leopard (10.5.6) and installed the Built-In Keyboard Firmware Update 1.0 that is suppose to fix the ignored first key press problem. Ever since then I have had constant keyboard & trackpad failures. When the built-in keyboard fails, thankfully I can still use an external USB or Bluetooth keyboard & mouse. I've tried everything. I've reinstalled Leopard four separate times, reset PRAM, reset SMU, repair permissions, pressure on the keyboard cable under the battery (even though I don't think this version of the MacBook has that problem). Nothing restored my internal keyboard and trackpad. During this process I tried to re-install the Built-In Keyboard Firmware Update using the original package file that I had downloaded, however I was given a message that the keyboard didn't need to be update because it already has the updated functionality and the installer package would then quit. Then I remembered that the original firmware update actually installed a Keyboard Firmware Update application in my Utilities Folder. When I ran the Firmware Update application in the Utilities Folder it instantly fixed my keyboard problem! Unfortunately the keyboard fix is not stable. It fails 2 to 3 time a week. Running the Keyboard Firmware Update application fixes the problem every single time, but this renders my MacBook useless as a portable (I have to have an external keyboard/mouse to run the Firmware application). I have, incidentally, tried all the other suggestions in the many keyboard threads in this forum (putting the computer to sleep, restarts, shut downs, PRAM & SMU resets, repairing permissions, running other applications, etc.), and nothing works except reinstalling the Keyboard Firmware Update using the application in the Utilities Folder. At this point I just want to downgrade to Tiger and go back to the way it was. I'll happily take the ignored first key press problem over a completely dead keyboard.
Please help.

Hi,
I was just wondering how you were able to get the macbook to accept the update? I had to take mine to apple store and get entire keyboard and trackpad replaced in my macbook. They then told me to ignore the update cause they did not have any other keyboards to replace if it happened again.

Is there a way to downgrade from iOS 5.1.1 to iOS 4.1 without any unauthorised modifications (e.g. jailbreaking)?

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.

15-f019dx downgraded from windows 8.1 to windows 7 home premium 64 bit: need drivers

Hp Pavilion 15-f019dx downgraded from windows 8.1 to windows 7 home premium 64 bit.
Stopped:
Internet driver

Network Controller
PCI Device
PCI simple communications controller
SM bus controller
maybe other stuff I haven't noticed?
I see others on this forum have had similar problems going back to windows 7. I tried some of their driver solutions that were posted, but to no avail. Can I get some help? Maybe some links to where I can find drivers to help me? Windows update cannot find and automatically install replacement drivers.

Hi:
Looking at the hardware specs for your model you should be able to use all of the W7 x64 drivers and software from the HP Probook 450 G2 on your model except the BIOS and firmware files.
Your model uses the Intel HD graphics driver and the Realtek RTL8188EE wireless card driver.

Downgrading from Win8 to Win7 envy 17-j021nr drivers needed

I have a customer who is running some software that doesn't like win8 so I am downgrading his new envy17 to win7. I've managed to get all of the other drivers installed and working but it doesn't seem to matter which additional drivers I try to download from other models I can't seem to get the realtek wired lan to work, the usb controller, or the synaptics touchpad. Does anyone know which drivers will work for this model.
Thanks for your help, it's greatly appreciated.
This question was solved.

Hi:
You should be able to use all of the drivers and software from this model, except the wireless.
When you go to install the graphics, you have to install the Intel HD graphics driver, reboot and then install the nVidia graphics driver.
DO NOT USE ANY BIOS OR FIRMWARE DOWNLOADS FROM THIS LINK

Iphone stuck in emergency mode after downgrade from 4.0.2 to 4.0?

iphone stuck in emergency mode after downgrade from 4.0.2 to 4.0?
Upgraded to 4.0.2 last night. Immediately, itunes would no longer detect my iphone. Decided I had to downgrade back to 4.0 again. Learned I cannot do that easily, so i found a .ipsw file of firmware 4.0 online, and downloaded it. Started up my iphone attached to itunes in restore mode, held down shift, and clicked restore button. Successfully restored the 4.0 file I had downloaded.
At the first boot, it was stuck in emergency mode. I even tried to restore the default itunes backup after that, it was still stuck in emergency mode.
Anyone know how i fix this iphone? I have no interest in jailbreaks, i am in a 2 year contract with AT&T.

omg, it just fixed itself! i installed a brand new itunes on my laptop (which has never had itunes app before)
plugged in my iphone, it detected it right away and said "activated"! my phone is working again and has its phone number back.
now i did notice that the 4.0 is indeed slow, so i do want to try going back to 3.1.3 also.

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.

I use iphone 3GS, can I downgrade from iOS4.3?

I use iphone 3GS, can I downgrade from iOS 4.3?

Since the 3GS, any firmware you restore is checked with Apple's servers for approval. They generally stop approving installation of older firmware soon after releasing an update in order to help curb jailbreaking activities.
In the past, although Apple does not officially support downgrading, it was often still possible with some workarounds, but following this change, it is usually impossible.

If I were you, I'd try to figure out how to downgrade from Vista back to XP. That would probably fix all of your issues.

Firmware downgrade on iPod Touch 3G 32GB

I just upgraded from an iPod Touch 3G 8GB that had 3.1.2 running on it to a new iPod Touch 3G 32GB that came with 3.1.3 out of the box. I've noticed that there are some things that the 3.1.3 OS just won't do and was wondering if there was any way to downgrade to 3.1.2 on my new iPod. I've got a copy of the 3G's 3.1.2 firmware and attempted to install it in iTunes using the <Shift> + Recovery method, but iTunes refuses to install the older software, giving the error that "this device is not eligible for the requested build".

I just recently downgraded from 3.1.3 to 2.2.1 on my 2nd generation itouch.
I went into DFU mode and did the itunes "Option" restore and picked the new/old software to restore to that I downloaded to my desktop. Now my Wifi works great! 3.1.3 which is being used on the ipad in my opinion is the reason why wifi is sketchy on it. I wish someone would downgrade the ipad to 2.2.1 and then check their wifi signal strength. I would be willing to bet it is in the 3.1.3 that is causing all of the ipad's problems with wifi. Apple told me the same thing " You can't downgrade your itouch". I just proved that is a bunch of Malarkey "Exaggerated or foolish talk, usually intended to deceive: " My two cents.
They just don't want to look bad by everyone going back to 2.2.1
Imagine all of the PC people downgrading from Windows 7 back to XP what an impact that would make to Microsoft.

Firmware update from my carrier (Cosmote)

Hi,
When I connect my iPhone to iTunes, I have a message which asks me if i want to install on my iPhone a new firmware update from my carrier (which is COSMOTE - Greece).
I would like to know what does this update, I am afraid it could block free internet tethering or Skype calls through 3G networks.
I have another question: is it possible to permanently disable firmware updates in iTunes? (Because one day I could make a mistake and click on “Yes”)
Thanks,
Eric

There is no Apple supported method to downgrade.
