Downgrading from Lollipop to KitKat?

Are there any steps to downgrade from Lollipop to KitKat? Not trying to be a pain here, but Lollipop needs some work, and i would rather downgrade to kitkat instead of waiting to get lollipop 5.1 update? Just having several issues (battery problems, contact app crashing randomly, bluetooth connection problems, wipe cache partition has already been done)
Any thoughts, suggestions on how to do this without rooting my phone?

Downgrading a Sony Z3 Tablet Compact tablet SGP612 from lollipop to kitkat for remote play

Hi,I was hoping someone would be able to help me downgrade my Sony Z3 Tablet Compact tablet SGP612 lollipop 5.1.1 to kitkat 4.4.4? It is a UK model. I bought this tablet solely for remote play streaming from the PS4. The streaming worked ok when I first got the tablet but was close to perfect when the 60fps PS4 firmware came out. Then lollipop came out and unfortuantely there has been massive lag with remote play on my tablet since, this includes the latest 5.1.1 lollipop update. I can confirm that I have done a fresh install of 5.1.1 from the PC companion app but there is still noticeable lag in remote play. I also have a decent Asus RT-AC66u router running Merlins firmware and the tablet is connected via 5ghz.
So on 03/08 I decided I've had enough and followed the guide to downgrade to Kitkat at http://www.xperiablog.net/2015/03/17/guide-to-installing-xperia-lollipop-using-xperifirm-and-flashtool/ but the problem is the kitkat 4.4.4 firmware is no longer in the Xperifirm list of firmwares there are only 2 versions listed which are both lollipop, can someone please advise where I can get the appropriate kitkat firmware? I am not rooted and don't want to be as I would like to keep my DRM keys etc. Thank you for all of your help. Matt

Thommo, Thank you for your quick response and your help. I don't suppose anyone could possibly help with a UK version of the firmware? I am unsure what filename the UK version would be so unfortunately I'm unable to search the web for this.

Downgrade Z3 compact (and others) from Lollipop to KitKat

Does anyone know of a method to downgrade it to 4.4.4? I don't like Lollipop.
Thanks.

You can either check XDA for a firmware or make your own for manual flashing
Guide to create your own generic .ftf firmware file for your country
The Flashtool link in that guide is old so use the new one here
Follow this guide to manually flash but use the .ftf you created above and not the one listed - Everything else is the same for all Xperia devices

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.

James,
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.

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!!!!!!!!!!!
Regards

Hello 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.

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.

Is it still possible to downgrade from ios 6 to ios 5.1.1 on my ipod touch 4th gen as of Sept.24?Also, if I use a backup created AFTER updating to ios 6 when I restore/downgrade to ios 5.1.1, does it become ios 6 again because of the backup?

There has never been a legit way to downgrade.
It will always restore to the latest available software.

Downgrading from Windows 8.1 x64 to Windows 7 Professional 32bit on HP 15-r036tu

Hello,
Is that possible to downgrade from factory installed windows 8.1 to windows 7 on HP 15-R063TU Notebook?
Please guide for neccesary steps at earliest.
Regards
Arvind Singh

Why 32 bit? I do not recommend that but here is a past thread dealing with your exact question:
http://h30434.www3.hp.com/t5/Notebook-Operating-Systems-and-Software/Downgrading-from-Windows-8-1-to...
The "downgrade" will not be free. You will have to buy Windows7 or have a real licensed copy available.

Downgrade from Windows 8.1 enterprise to windows 7 Ultimate or Professional

I have installed windows 8.1 and am not happy neither with its performance or it's UI; I have my own copy of Windows 7 Ultimate can I downgrade from Windows 8.1 to Windows 7 Ultimate? I need to keep my applications and files.

Hi,
Like Carey said, you need to format the whole drive and do a clean install. The most important is don't forget do a backup in an external hard drive. You will be need to restore it after roll back to Windows 7.

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
Wireless
USB controller
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.

How to downgrade from ios 8.0.2

how come there is no way to downgrade from ios 8.0.2 to ios 7 !!! i don't think its legal from apple to close the way back
but let me ask may be there is something i don't know
is there any way back to ios 7.1.2 ????
thanks
kh

There is no way to downgrade. Apple probably doesn't allow it because then people would downgrade a lot. People rarely like the new update when they download it. Also, Apple doesn't support past iOS things…So if someone is on iOS 3, Apple wouldn't support fixing problems or whatever (if I remember right).
So, sadly there is no way to downgrade. Sorry!

How to downgrade from iOS 8.3 back to iOS 8.2?

How to downgrade from iOS 8.3 back to iOS 8.2?

A handful of people scream about every update that is ever put out. It is the nature of technology and blame. Perhaps try addressing your issue instead of blaming yet another update. you would never had of installed 8.2 if you took these forums as any true representation of iOS users.
