[Q] Is it possible to undo a kernel once installed?

I'm using the stock Gingerbread "Leak" rom version 4.12.651.1 that was leaked recently and I played around with it at first. Took several pictures and videos and enjoyed getting back to having Sense on my phone.
I used Kernel Manager Lite to download and install the Netarchy Toastmod-cfs-havs-more-sbc kernel and at now everytime I open up the camera it shows a white screen and I can't take a picture or video anymore.
Is there a why to uninstall or undo this kernel without having to reflash my Evo? I'd like to go back to just the stock kernel i guess. I even tried to use the Kernal Manager Lite to download and install a different Netarchy Toastmod kernel but it wouldn't install it over a previous kernel and when I clicked on the kernel I already have installed it won't give me an option to uninstall it...
Thanks for any help you guys can give me.

Find the stock kernel for that ROM and flash in recovery after wiping cache and dalvik cache.I will try to find stock kernel for that ROM.

Yeah there's no way to undo once u flash a kernel.....may I make a suggestions for ya foe the future.....Ive been doing this for a while......flash the ROM and make a backup once yur all setup...this way u can tinker with the rom and kernels and themes and what not.......and if those tweaks don't work for ya......u got a backup of a fully stock rom......

Thanks guys for the awesome advice!
Reverepats, it's funny you said that because that's the first thing that I thought about after this happened and I'm still kicking myself for not backing it up before flashing the kernel LOL It'll be a lesson learned I guess
Ianmb, that would be AWESOME if someone had this. I'll keep looking for this too but if I have to I guess my only recourse would be to wipe it all and reflash all over again... /sigh

There is a post for a working kernel for that ROM on the second page if the ROM is the stock 4.xxx. Stock kernel 15 I think, can't upload file from my phone?

ianmb, thanks for looking but I can't find any stock kernel #15 out there. not even google can help me =/
So it's possible to reflash a kernel over an already installed kernel? If i find the stock kernel how do I go about installing it? Via recovery?

Forgive me if I'm wrong...but if you just reflashed the rom without wiping, I believe it would install the stock kernel that came with the rom

Yes you can flash a new kernel over an installed kernel...just wipe cache and dalvik prior to flashing

Can't boot on CM10

I have some questions and need help fast if possible. I'm currently on CM10 beta 2 and only have a nandroid backup from being stock rooted. I know you can't simply restore a backup from jelly bean to ICS. I was playing with ROM Toolbox, and was installing some custom transitions. I did a backup of the stock transitions, but the zip backup file won't flash in recovery. Anyway I can't boot up and only get the Galaxy S II boot screen. I can however get into download and CM CWM based recovery. I've done quite a few searches, with no real answers for this issue. Any help will be greatly apreciated because I don't have my phone until I figure out exactly what to do. Do I have to download a stock ROM with cusom kernel to computer then transfer over file via usb using Odin and then use CWM to flash the stock ROM? I know not to do a factory wipe unless I'm on el26 or 29. I also know you can odin to them then flash, but all the odin kernels with CWM are from ICS and I can't find a solid method for my specific situation.

Flash any one of the stock full roms using this - http://forum.xda-developers.com/showthread.php?t=1903252 Preferably flash official builds.

Thanks Blues.

jtadak said:
Thanks Blues. But I need to flash el29 or six before flashing right? So I'm guessing I need to Odin to one? And I can do that from any ICS or JB right? So I just need the one click for PC Odin, then flash with Odin? Sorry, I just want to be 100% here.

Use the one click.exe full rom file that will flash the full el29 gb rom. Then from there you can flash cwm to flash cm10 or whatever rom you want.

But do I have to go el29 or 26? How do I get there from where I'm at now? Thanks again, and sorry I just want to be 100% here.
Edit: Okay, great. After flashing that I obviously could do my nandroid restore? Just because I lost some pictures or something happened when I flashed to JB because I only had a few pics and none of my SMS or call logs or anything came through.

Ok, just so the thread is not a complete waste, I did flash the stock ROM via PC ODIN. Went back to stock, was able to do a nandroid restore, and went ahead and flashed CWM recovery via Mobile ODIN. Went ahead and wiped factory in CWM recovery and flashed CM10. Thanks again Blues, next time I'll just post in your noob thread. . I'm not a noob but I just never had to PC ODIN when not being able to boot and wasn't sure how safe it was in my specific state.
P.S. Any other users are more than welcome to P.M. me if you have any questions. I probably won't visit here again

[Q] Wipe data & cache via odin???

Hey guys, I was having some trouble with a rom and switched my recovery to CWM6.0.1.2 and it's no longer booting recovery and CM is not working either just getting boot errors with gapps and setup crashes.
Basically I can't do anything with my phone unless I can wipe it and flash stock or correctly flash CM. Does anyone have any suggestions on a way to wipe my rom through odin? Currently downloading stock just incase that may help me down the road.

Where is that stock rom? Looking for it

Download CWM from my signature and flash it through Odin.
Gapps crashing means you flashed a mismatched version for your rom.

That might have happened, I got CWM working and flashed my old rom with a lot of issues, specifically stock apps crashing. Going to flash full stock via odin and start from scratch. Really stoked to try a 4.2 CM AOKP rom :good:
Are there files I can manually delete/modify to bring my device fully back to stock?

Delete or wipe via recovery is highly recommened and flash via odin. You cant do to all system files and delete them individually; thats too much of work.

Everything is golden thanks guys

[Q] S3 4.1.1 Kernel

I can't seem to find this kernel on XDA or google.
Im on my SGH I747M 4.1.1
with kernel 3.0.31-538866 [email protected]#1
Where can I get this kernel to flash?
Reason why I'm asking is i'm trying to flash new kernels and want this as a back up to have it stored so i can restore it.
Unless....TWRP recovery images can recover the kernel when you restore that image?
Thanks!

When you restore your backup, it will restore the kernel as well.

It's in your ROM zip. Named zimage. Extract that file and you can flash it using Odin.
You can also dirty flash the ROM (without wiping) and it will reflash it.
Btw, reinstalling the kernel doesn't do anything if it's already on your phone. It won't fix anything. If you flashed another kernel though, that's another story.
May we know what you're trying to fix?

[Q] Rom Question

I'm having issues flashing multiple roms of the 4.x.x Roms. The only rom so far I have been able to install and actually run on my phone is TweakWiz V2. I have tried many other roms and they just stay in a boot loop screen. Examples are with the Avatar rom it just stays on the mask an keeps going and going. I have tried CyanogenMod/Cyan Kang an it just stays on the Circle with the bar going around on the inside.
I am running the TWRP Touch Recovery. I also have the latest Radio update and everything else is updated on my phone.
I also let the install itself run for 10+ minutes everytime. But all the roms I try they keep doing the exact same thing and staying in a boot loop.
Can anyone give me any tips or suggestions to maybe something I could do to use another rom or maybe even a suggestion to something I may have overlooked.. Any help is appreciated. Thank you.
An if you need me to give any other information let me know an I will provide.

1. what recovery version not just the name ?? 2.steps you are doing to flash 3. steps you are doing after you flash

1.Im using the latest TWRP.
2. Wiping System, Cache, Dvalik or whatever. I wipe everything in the usual instructions. And I make a backup of previous ROM. Flash the ROM then the G-Apps.
3. After I flash I let the ROM run its course an I wait from 15-45 mins for the ROM to load if it doesnt I switch back to TweakWiz or try another.

try using this recovery since the recovery you are using is the latest one and technically for 4.3 ROMs, give this a shot http://techerrata.com/file/twrp2/hercules/openrecovery-twrp-2.5.0.0-hercules.tar its the same recovery but lower . the steps you clarified seem very proper but your recovery may be at fault crossing fingers try flashing that recovery through odin or download the zip from the same website and report back after trying to flash again

Are you sure you are wiping DATA also?
You will need to do this, if you are flashing a 4.2 or 4.3 ROM, then you will also want to wipe the pre-load. Then flash the rom, and gapps.
Use the newest TWRP 2.6.1.0 to flash anything, don't need an older recovery to flash older ROM's.

Is there a option I'm not deleting ?
Because I've been flashing ROMS on different phones an I have never had any issues before. I was using ICS an GB etc before an just recently decided to upgrade an use the JB (I think that's the name.) on my phone.
