Is their a way to downgrade Android 4.1.2 firmware to 4.1.1?

Can I downgrade my firmware on my Nexus 7? If so, how do I do that?

Why do you want to do this?

If I understand right (and note it's very well possible I don't), you can just get a ROM/Kernel, or stock factory image for 4.1.1, and flash it, after wiping out the device.
The bootloader may or may not need to be downgraded as well, but I would also assume this to be a simple flash once the old bootloader is wiped (obtainable from 4.1.1 factory image).
But as asked, why would you want to do this?

Stupid question, which factory image should I download and flash?

I'm currently running 4.2.1 and want to upgrade to 4.2.2.
So can I just download the 4.2.2 factory image and flash that, or do I have to download 4.2.1 and then do the OTA update?
Thanks.

The factory images are images in their own right, ie download 4.2.2 only and flash it.

[HELP] Downgraded S4 from stock 4.3 to 4.22 Failed. Stuck with Samsung Logo

Hi all,
I tried to downgrade my S4 from the stock 4.3 to the 4.2.2 using odin. Odin success without any error.
Phone rebooted, but stuck with the Samsung logo.
Did I just brick my phone?
Any help? Thanks.

Did you do a factory reset BEFORE doing the ODIN flash downgrade to 4.2.2 ?
If not you need to do that and reflash using ODIN.
Also be 100% sure that you are flashing the correct and specific model/baseband
version of the 4.2.2 stock firmware for your phone.
Only use/download ODIN flash stock official firmware from: http://sammobile.com
for best results.
Good luck!

I would factory reset my phone but I would still get a error, does the process only work with the international version of the S4? because as far as t-mobile, I don't think we have any luck in downgrading to 4.2.2

all you need is reflash official 4.3 firmware using odin. once updated to 4.3 it is impossible to downgrade to official 4.2.2.
so just reflash 4.3 official again and your device will boot up. i myself faced this problem .

so it's impossible to downgrade to official 4.2.2, but is it possible to flash a custom stock rom on 4.3 or 4.2.2 (like a modified stock rom)?

You've most likely got the KNOX bootloader due to this you can not downgrade to an earlier version of an official rom. Custom rom's should work fine not sure about 4.2.2 roms.

Would a equalivalent version of a custom rom work? because I plan to install jovy23's stock SGH-M919 4.3 modified rom, but I am not able to install it due to the errors given by CWM and TWRP

Update 4.4 to 4.4.2

I just received the OTA update of 4.4.2 so I wanted to know what exactly I have to do to update without any errors. I'm Rooted on Stock 4.4 with unlocked Bootloader and Custom Recovery TWRP and also I have the LTE hack enabled. Do I just fastboot flash stock recovery and let it update through OTA or do I have to push the original build.prop from 4.4 too because of the LTE hack? I really don't want to factory reset because I had to do that before in order to update from 4.3 to 4.4. Thanks in advance guys.

I literally just flashed from 4.4 to 4.4.2 by flashing the entire factory image. I didn't lose any data. Same boat as you, rooted and using TWRP with LTE hack.

Downloaded the 435mb OCCAM KOT49H factory image from google? Then you put the entire .zip on the sdcard and flash it through twrp? Is that it?
I'm rooted and have twrp also, but i don't know if i can just flash the full factory image. I want to be stock and rooted!
Thank you!
EDIT: Sorry, i have found the solution in here: http://forum.xda-developers.com/showthread.php?t=2145848
I didn't know you could download these files and use them as "manual OTA update"..
Thanks again

I guess its not possible as boot loader gets updated too.
but you can try flashing the 4.3 firmware if you already have it.
press thanks if I helped you.

Yeah, thats no problem. Just flash a factory image of 4.3 and you are good to go
