Hello, I'm on 4.2.1, but the phone keeps offering 4.2.2, it downloads it, but I can't install it since i'm on custom kernel and phone is rooted.
My question is that if I install the stock kernel, will I be able to install the update OTA?
If yes, then where can I get a 4.2.1 Maguro stock kernel?
Use this app to unlock your bootloader if you haven done so, then extract boot.img from the stock google image(which can be obtained here for older versions). Then flash the boot.img in fastboot.
Code:
fastboot flash boot boot.img
Anyway, I don't think you will download the whole stock image just to get a 4mb kernel, luckily i have the stock image lying around, so download it here.

Hey guys,
I'm one of the many Galaxy Nexus owners that don't like their battery usage at all. The device is a yakjuxw build running 4.0.1.
First thing I wanted to do was to update to the official 4.0.2 image from Google. Now lurking through all these threads I saw that most of you recommend franco's kernel for its awesome battery performance. By flashing that custom kernel will I still be able to get OTAs? (on a stock official 4.0.2 image)
Also, some of you reported that the 4.0.2 OTA was pulled back due to some issues. Should I still flash the 4.0.2 image in this case?
Thanks,

To flash a kernal, you need a unsecured boot.img. Its is usually provided with roms but if you want just the Kernal you will need it. To flash that you need to flash recovery Clockworkmod preferably.that will not stop you from getting otas but ubwont be able to install them as ours need stock recovery. So in essence, yes it will prevent you

You need clockwork to flash a zipped file. To flash a boot.img all you need is fastboot. And i highly recommend manually flashing 4.0.2. You dont need clockwork recovery. And flash a radio more suitable to your region. That too will help battery life.

I thought that if you don't delete the boot recovery image using the root explorer app, once you restart the phone CWM will be overwritten by the factory default image. So shouldn't that allow OTAs to be applied?

So just flashing the 4.0.2 will still get me OTAs right? And all I need is fastboot for that, am I right?

You won't be able to use Franco's kernel unless you flash to a rom based on 4.0.3. You can always go back to stock as long as you have cwm recovery. Users always post stock back ups that you can just copy to your phone and restore from.

Im currently on atom v9, which is 4.2.2, but i wanna flash the new pa 3.1 which is full 4.2.2 which needs the updated baseband and bootloader. My bootloader is currently PRIMEKK15, and i tried to flash the new primcl03 zip but it just says failed in twrp. is there any way around this?
how did you flash the TWRP?? do it as the same way you did flash custom recovery using fastboot
you can get the latest bootloader and radio (in the factory image tgz file) at http://developers.google.com/android/nexus/images
this is my first tablet and nexus device.. when i got my nexus 7 a few weeks ago.. i took the 4.3 update OTA... then rooted it unlocked it and flashed a custom rom.. i see that theres a new update small im guessing 4.3.1 what do i need to do to update my nexus to that?? can i just flash a 4.3.1 rom?? thanks also what do i do to update my nexus in the future when there bigger OTA'S i kno on my htc one i have to either unroot and go back to stock and take the ota or wait for a dev to make a firmware zip for rooted users to flash.. is it diff with tablets?
You could either flash a custom ROM through recovery on the phone or flash the stock images with fastboot on the computer.

If you use the flash-all tool (refer to: http://forum.xda-developers.com/showthread.php?t=2382051) both your ROM and recovery will be back to stock.
hi guys new to the galaxy phone and i have been looking into flashing a rom. i have done all the ground work root and custom recovery but now im trying to flash a rom and i get errors. i looked it up to a point where everything i do want to flash requires a 4.4 or 4.3 update and i am stuck in 4.1 is there any solution to this like start from an older rom and work my way up to a current rom. would that work or odin the phone to a current update if possible to find the update. what options do i have ?
not sure if this is the correct thread
Well I would just flash via Odin up to 4.3 because most Roms require the 4.3 boot loader so yea

I recommend you not update to the 4.3 bootloader as the 4.3 bootloader can cause problems when trying to flash back to stock. Once you're on a 4.3 bootloader, you cannot downgrade to a lower version. Most ROMs seem to work fine with a 4.1.1 or 4.1.2 bootloader.
If you have the att s3 (i747) and not the Bell/Telus/Rogers s3 (i747m), you cannot use Odin to flash a stock 4.3 ROM as it does not exist. You would need to flash a version of 4.3 that has been custom compiled for flashing via Odin.
I would download the latest version of Philz Touch and flash the tar version via Odin. Copy a custom ROM to your SD card, boot to recovery, wipe cache, Dalvik, data, and flash the ROM.

I rooted my dad's phone a while back ago so he can use tethering in case of emergencies etc. He recently got a smart watch and I wanted to updated it so that he can use it. But it has not been touched since that day. I essentially want rooted stock rom, I'm unaware of where to find that the closest I can find is StockMod kitkat. Which seems to not work on ATT phones? I just want to make sure that I don't brick his only phone on christmas. So is there something I should be aware of?
His model is SGH-i747
Baseband
i747UCDLK3
Build number
jro03
So how do I go about upgrading it? Can I just flash TWRP and flash any rom using TWRP?
I found this, so I should install new TWRP, then flash a specified kernel then flash rom? would this be safe route?
Some of the latest ROMs require a 4.4.2 bootloader and modem.
The simplest and safest way to get the latest bootloader may be to flash back to unrooted stock 4.1.1 and run OTA updates until the phone is running the latest KK ROM. You can then flash TWRP or CWM and a custom ROM.

Would this require flashing with ODIN? I just want it so that it works with root is not required anymore.
Yes, you would flash the 4.1.1 stock ATT ROM via Odin. I prefer Odin 3.07.
You cannot install OTA updates with root.
You can try flashing just the bootloader and modem but I prefer the long slow route of OTA updates.
I rather do it this way, manually so my dad can enjoy it today. I was wondering how can I update it's TWRP? it's at 2.3 but the TWRP manager keeps crashing when I update it.
I highly recommend the latest d2lte version of Philz Touch for recovery.

Ok I ****ed up, flash that kernel and did whatever and bam ****ed up. Not working... ****, I still ahve download mode and Recovery but it will not boot into the OS. I get a flash of samsung and then nothing else happends...****
I decided to flash stock DLK3 in odin. Then let the updates take it course (my dad doesn't need root) Where Can I find the file?
The stock ATT firmware is on sammobile.com.
If you want root, OTA to the latest 4.4.2, install Philz, flash supersu via recovery.
