hi guys..recently i thought of flashing a custom kernel but i would like to backup a stock 4.2.1 kernel just in case things get messed up..
is this the latest kernel for 4.2.1? http://forum.xda-developers.com/showthread.php?t=1997474
it's stated that it's for JOP40C but i understand that 4.2.1 is JOP40D..so i'm a little confused here, is this the latest kernel for 4.2.1 or 4.2.0? hope someone could clear that up for me..thx:good:
anybody?
You can always make a nandroid backup of your rom with stock kernel, or dirty flash your rom without wiping anything to get back to stock kernel.

I have been running Thor's ICS builds and since I see the official ICS rom is out I wanted to go to that. I assumed I could just revert back to the 3.0.1 unstable rom after removing CWM recovery but I was very wrong apparently...
I removed the CWM recovery and flashed the unstable rom through stock recovery as a update.zip file, rebooted and now it gets to the android screen and just loops in that over and over.
I have tried flashing different Honeycomb roms but all of them do the same thing when I try to boot.
What am I doing wrong?
I am still rooted but I don't think that matters much at this point since I can't get to anywhere that would use it...
You must reset your device. I dont have the link here, but i found it here in the xda forum.

I Decided to go back to stock yesterday and have followed the many guides on XDA to un-root to stock 3.2. Unfortunately I'm an idiot and installed an A500 rom instead of the A501 ROM. I would like to know if it's possible to "Upgrade" from 3.2 to an a501 rom using a signed official rom and the stock recovery?
I'd really like to have the official A501 rom installed on my A501, call me crazy
I've tried to install a few stock roms by renaming the zip to update.zip and placing it both on my ext_sdcard and my internal sd of my tablet but none of them have given anything more than the green triangle android recovery screen. Can anyone recommend what I should do next?
Do I need to re-root and re-un-root?
UPDATE:
I discovered that when I flashed the stock a500 rom from my CMW recovery initially, it worked great and I could access the stock recovery with no issues. however in trying to backpedal and go back to root so I could flash the correct a501 rom I rooted my rom and flashed a custom recovery without first flashing an unlocked bootloader. Then when that didn't work I re-flashed the stock recovery. Pieces of the custom recovery may have been left behind OR there was a simple version mismatch. Either way, I've now flashed an unlocked BL, custom recovery, and flashed back to stock a501 3.2. Now I'm back to a501 completely stock and just waiting for an official OTA 4.0.3 update.
Just read on acer's website the A501 doesn't get ICS. How sad.
It's possible to flash an a501 stock rom over the a500 one. The stock roms you tried without success could've been encrypted and you'll need to use the acer update decryptor to decrypt them. http://forum.xda-developers.com/showthread.php?t=1099673
After decrypting the file with it, unzip it and use the included update.zip to flash your tab.

If I am able to open the zip file it's already decrypted right?
I wouldn't be able to unzip an encrypted zip file afaik
Yes.You're right.

I have it but still no update. I know it takes a while sometimes.
I am experiencing some weird touchscreen issues. I turn my screen back on, and the touchscreen goes crazy. It's not like the normal lag, the screen goes crazy until I do a full reboot. So I decided to go back to stock and look if the issue is still there. I found this zip with a stock rom: http://forum.xda-developers.com/showthread.php?t=2251958
So I have a stock rom after flashing, but the recovery is the same. So how do I only flash a stock recovery? Maybe if possible from CWM?
Atm I am on cm10 with pa stock kernel with modified colors.

Flash official stock and re-lock the bootloader.
You can get it from http://forum.xda-developers.com/showthread.php?t=1995688
or google's website.
I searched through here a little but didn't see it exactly so don't kill me for asking. I think I've decided that I'm going to sell the phone and am putting it back with the latest OPPO ROM and I want to remove TWRP and install the original OPPO recovery.I'm downloading the OPPO ROM currently and will be putting this back to stock this evening.
Thanks!
If you flash the Oppo ROM, you flash the stock recovery automatically.

Hi folks!
I'm one of the the few lucky ones still being on the pre-KNOX 4.2.2, buildnumber JDQ39.I9505XXUBMGA. I own the international (swedish unbranded) version of the I9505. At the moment i have Root and a custom recovery installed, stock TouchWiz.
Now I want to discuss the pros and cons of WHETHER staying on this version, installing a custom ROM and a custom recovery OR updating to Jelly Bean 4.3 and only having the possibility to root without voiding my warranty.
I'm wondering:
Are there are any improvements in performance and stability with Jelly Bean 4.3?
Is there a stable custom ROM?
Is there a stable custom ROM that uses all the possibilties on the SGS4?
The reasons why I want to have ROOT is the annoying inability to move app data to the SD card. I don't want to void warranty.
Every answer/idea/opinion is welcome!

Hi, first of all, you lucky guy can flash every custom ROM 4.3 and also 4.4.2 when no new bootloader is included.:good:
the Samsung based ROMS are fully working. All you have to do is to flash a ROM of your choice and update your baseband. It should have the same base as the ROM. So if the ROM is based on a NB8 firmware, you have to use a NB8 baseband. But flash only the modem.bin file, not the non-hlos file.
for working wifi use a custom kernel like KT or similar.
The performance and the batterylife are in my opinion much better in 4.3 and 4.4.2.
it depends on your using.
just try a little bit. As long as you not update you bootloader, you're on the safe side.

How do I know that a custom ROM doesn't contain the new bootloader? Does the bootloader come with the kernel? If so, which kernel versions are safe? Which custom ROM without new kernel is most stable?
Do 4.3 and 4.4 run on the old kernel? Are there significant improvements in the original kernel coming with 4.3?
After reading about 4.4 I absolutely do not want to update to KitKat.
Many questions but the amount of kernels and ROMs is simply overpowering for someone who does not have the time to read every post on XDA every day.
Seeing forward to your answers.
I'm pre knox and have flashed various rims including the Google Edition roms. Currently I'm on KitKat TW rom using the pre rooted debloated version. You'll have to update to the kitkat kernel but this is included in the rom. All custom roms that are flashable via recovery will not have the new bootloader. Knox is tied into the bootloader. Why don't you want to install kitkat? It's better overall with the new kitkat features.
I run KT kernel it's a fantastic kernel in my opinion and has many tweaks.

Thank you for your answer. I read about problems accessing the SD card in KitKat. Or is this not a problem with custom ROMs? I want to be able to move app data to SD card.
