[Q] Kernel Panic with Many ROMs. - Galaxy S II Q&A, Help & Troubleshooting

I am using SGS2 i9100 and rooted and CWM installed as follows:
1. PC Odin Flash LPB Firmware (ICS 4.0.3).
2. PC Odin Flash CF Root LPB Kernel.
3. Mobile Odin Flash Stock LPB Kernel to remove Yellow triangle.
4. Mobile Odin Flash CF Kernel again to get CWM Recovery as well as root.
So far everything is OK. I can boot to recovery and installed CheckROM v6. Perfect no problems.
Then decided to try MIUI (ICS) when it was released. After complete wipe, ROM installation completed and on reboot > Kernel Panic Upload Mode. Couldn't boot to recovery Just to Download Mode. Had to follow steps 1 to 4 again to get Phone working with root and recovery. Tried a couple of times with MIUI from different sources like miui.us or miuiandroid.com but same result. So back to CheckRom v6 which works without problem.
With recent better ICS ROMs available, tried to install Omega v1.0. Again Kernel Panic Upload Mode. Followed steps 1 to 4 again. Tried Omega 12.0 used by lot of people. Again Kernel Panic Upload Mode. Tried PC Odin Flash of Siyah Kernel. Got the Siyah screen to show on bootup but this remained a while ... ROM did not boot and then screen turned to Kernel Panic Upload Mode after waiting a couple of minutes.
After again doing steps 1 to 4 I am back on CheckROM v6 which works flawlessly.
Why can I not use any rom which tons of users are using? Is there a hardware peculiarity which is preventing this? Should I try out old or new or ICS bootloaders? I don't want to mess with bootloaders as I hear these can hard brick the device.
Any suggestions?
Thanks.
PS: My Complete Wipe steps are:
1. Remove user data/Factory reset.
2. Clear Cache
3. Clear Dalvik Cache.
4. Optionally Format system partition in mounts and storage.

The reason is obvious ....Why old LPB???? Stay away.....
Start again from the GB rom better 2.3.5 from odin
Root with cf root and flash any rom what you want from CWM...
No need to change bootloader again...the one you get along with the gb rom is enough further for all

OK I have KE8 (Gingerbread ROM 2.3.3 which is latest for my location) downloaded. Will a PC Odin flash of this remove my current troublesome bootloaders? Or should I download another GB Rom 2.3.5 or newer for PC Odin Flash?
PS: I used LPB assuming that an ICS Rom would give me the bootloaders which would not give me headaches from installing custom ROMs from XDA here. If someone could explain to me where my logic went wrong?
ZACQ8 you called LPB old, but wouldn't it be newer than the 2.3.5 GB ROMs?

Click to expand...
Click to collapse
you can flash the one which you are having now, but make sure CF-root is available for that to Root and install CWM, for your further flashing of ROMs,
yes that will replace the bootloader, but doesnt matter, it will be ok for all custom roms, (unless some Rom devs insist to replace bootloader first for their Roms)
I told the LPB is the old in the sence, it is old beta release among the ICS versions. Kernel Panic was highly reported while using this version.
Kernel panic Mode is hardly reported when people are coming from GB roms and installing Roms from CWM. that is why I sugested flash a GB rom from ODIN then move to any ROM through CWM.
You can also flash and try latest ICS version from ODIN.

Cool. That's the task for tonight then.
Sent from my GNex on AOKP.

if you are flashing a custom ICS ROM take the LP9 version,
one custom ROM with LP8 version has gaven me once the Kernel Panic
Goodluck

Thanks that worked. Installed Omega 1.0. Downloading Omega 2.1. No kernel panics. So from now the phone shoul dbe trouble fre hopfully.

wen u get prblms instead of keeping on flashing jus stop an ask..
flash stock gb after wipe..
then root properly..
don go for any rcs,beta,alpha root release....
then its a good idea to flash stock ics ...
wen u get a clear pic,u can go for aokp,aosp which will b diff...
bottom line kno some basics instead of jumping far away......cheerz

Looks like I'm in the same situation, I had used odin to flash with I9100_CODE_I9100XXLP2_CL57619_REV02_user_low_ship.tar.md5 back in Jan/Feb and flashed it with CF-Root-SGS2_XX_OXA_LP2-v5.2-CWM5 kernel.
I was then able to flash new ROMS no problem with CWN
Then flashed the other day with the latest Ressurection Remix 2.2 and am getting the dreaded "Kernel Panic...."
So I'm back to the I9100_CODE_I9100XXLP2_CL57619_REV02_user_low_ship ROM.
My plan is to flash it with a 2.3.6 ROM using odin, then apply the CF-Root kernel and from there I'm hoping I can then apply Ressurection Remix ROM.
I'm just a bit unsure of which versions of the ROMS to use, I haven't been able to find a guide to selecting the correct versions for my phone. Any pointers would be greatly appreciated.
