Stuck in Kernel Panic mode - Galaxy S II Q&A, Help & Troubleshooting

Hi guy's, was running the original Criskelo ICS rom, noticed there was an update available for it (while browsing on the phone). Jumped onto the PC but accidentally installed the version for a Galaxy Note or something like that. It was just showing a funny screen that would bleed from black to white as it got hot. Complete newbie mistake.
I'm pretty sure that's all sorted and in the past now (but maybe there is some hangover from it?). I installed the stock ICS rom, then flashed a kernal with CWM. Now, whenever I try to install the new version of Criskelo, it flashes fine and shows no errors but everytime it goes to start it goes into kernal panic mode. Each time I need to flash the stock rom, then a rooted kernal and try again.
I have tried flashing Criskelo in the CWM app, on both the internal storage and the external SD card, have also booted into CWM mode and wiped the cache, restored factory data and wiped the davlik cache, and tried to install)
I have searched but most responses on the subject suggest re-flashing which i've tried 4 times now.

just tried to put the older Criskelo rom on and it's done the same thing, kernal panic mode.
The kernal i'm using is the one I used originally when I 1st had Criskelo rom running.

bckup ur efs and stuff an i think format the mem card an phone on pc then flash a stock on it,an if ur imei or pcode messed ,ull have a bckup u made b4 so jus do the correct stuff...sometimes u hav to take risk wen ur careless wiv the device.......hope it helps

thanks for the reply. Can I just remove the memory card and format the phone only (memory card is a 64gb)? What shall I use to format the phone? I've lost SD cards in the past using the format that's part of windows. Would hate for anything to happen to the phone.
Shall I do this process http://www.jayceooi.com/2011/07/18/how-to-hard-reset-samsung-galaxy-s-ii/

I've got no problem installing a standard official rom and then rooting the phone. The problem is when I want to then flash a custom rom

i've just wiped the phone, formatted it and the SD card. Still the same issue. I don't understand what's going on. I might try a different custom from and see if the same thing is happening.

have you flashed anything from ODIN befor?
this time you must install an official rom from ODIN, still dubt feel free to ask

i'm flashing the original rom via odin. That's installing fine and i'm flashing the rooted kernal through odin, that's also working. When I try to flash the Criskelo rom i'm using CWM to flash it. I don't think the rom can be flashed by odin can it? It's a zip file rather than .tar files.
If there is a way to do it via odin, i'll try that?

Are you able to get downlaod mode with vol-down+home+power?
download this one http://skywanker.net/download/downl...9100_DBT_I9100XWLA4_I9100XXKI4_I9100DBTKH1.7z
and extract it then you will get a file ...MD5, select that file from ODIN PDA section and flash...

oho ....you are no more stuck in the Kernel Panic now, only when you install that perticular ROM?
then you try flashing Siyah kernel from ODIN after installing that ROM
---------- Post added at 07:06 PM ---------- Previous post was at 07:02 PM ----------
if Criskelo rom is an ICS one use this one http://gokhanmoral.desean.net/siyahkernel/v3.0/Siyah-v3.1b1.tar
flash from ODIN,

i've just tried to install another custom rom, this time it just stayed on the boot screen rather than kernal panic.
I'm wiping it back to stock (ICS rom), then i'll install the kernel you just linked me to and try criskelo again, is that what your suggesting?
edit.....
Just installed the standard rom. Flashed the Siyah kernal via odin and it re-booted into kernal panic upload mode. That's not happened before. The 1st time I flashed the kernal it didn't do this.
I'm really confused...

"standard ROM" you told is ICS or GB?...it must be ICS, otherwise wont work,
I told you the Siyah kernel link which I sent you only use with an ICS ROM,
you start from biginning again, flash the official ROM (not the ICS a GB rom) and Root with CF- kernel and install your desired custom ROM, should be working fine...
Crickelo V38 is not an ICS ROM it is GB rom...

Siyah 3.x and higher is for ICS.
Siyah 2.6.14 and lower is for GB.
There are also ICS only versions of SpeedMod and other kernels.
You must pay attention to what version of Android a kernel is meant for before flashing.

I'm trying to install this rom. CriskeloServanRom SGS2 4.0.3 oficial Firm XXLPQ
The 'original' rom i'm installing is a ICS one for my phone. That flashes fine every time. When I flash a rooted kernel that also works fine, it's just flashing with CWM that's giving me these troubles
edit...
The rooted kernel is CF-Root-SGS2_XX_OXX_LPB-v5.2-CWM5-PROPER.tar which matches the LPB code on my phones firmware.
Since i've been trying to flash the Siyah kernal, it's giving me the same "kernel panic upload mode". When I was flashing the CF-Root-SGS2_XX_OXX_LPB-v5.2-CWM5-PROPER.tar kernel that wasn't a problem. The problem came when I tried to flash roms with CWM

[Q] Galaxy S 2 not booting with any custom kernel

Hey guys,
So i have my S2 for like 6 months now and never had any issue with flashing custom roms/kernels till yesterday. i installed XXKI4 and everything went perfect.
Few hours later i decided to flash CM7( wiped system,data,cache dalvik etc and flashed the zip 2x) so after this i rebooted my phone and it gave a bootloop. I was not able to boot in recovery mode so i had to reflash with odin to a stock rom. Well i did that and i was on stock rom again. i decided to flash the latest speedmod kernel, i flashed it and bam phone not booting, shows the Samsung Galaxy S II GT-i9100 text with the yellow triangle and its stuck at this screen for an hour now. i just cant use ANY custom kernel/rom on my phone because they all give bootloops and i want CM7 so bad. Any idea's and suggestions will be truly welcome.
Stock Samsung Roms are working great, but dont want that ;p
thx!

Have you done 2x flash in a row of CM7? its a know bug (but unknown reasons) it just dosnt start until you flash it 2x in a row.
Suggested method:
1. Enter ClockWorkMod recovery
2. Wipe data/cache factory reset
3. Wipe cache
4. From mount and storage menu, use Format System
5. From advanced menu, use the Wipe dalvik cache
6. Flash CM7 latest nightly
7. Reflash CM7 latest nightly
8. Reboot the phone
Not sure if this can help you, since you experience a problem that is not exactly the one i saw some times on forum (you cant even enter recovery mode after the flash) but this is how usually ppl makes CM7 work
Oh on a side note, i suggest to not use rom manager, it's confirmed (at least, from various posts here on xda) to not be really 100% working on our SGS2 and can cause problems.
If all this isnt working, it may be worth downgrade to KI3 or KH3 stock one, root again and then do the above system.
I can assure you 100% this system works over KI3 and KH3
yep you need to flash 2 x CM7.
First time it will flash very fast.
Go back to the stock rom and then install CM7 again
can you boot in CWM or are you getting some errors ?

nah, this won't do it, believe me! coz i have exactly same issue with mine. I've done this countless number of times and nothing works... i just came to accept the fact that my phone doesn't support custom anything whether kernel or ROMs, until someone finds out the solution.
meanwhile you can try siyah kernel 1.7.8 or so, it worked with mine, see if it works with yours.
cheers!

i know this problem, my phone was stuck at boot too but i flashed back to stock rom and i fixed my phone. my problem was i can't use cwm its was dead.
i already tried to flash cm7 like 10 times and it doesnt work i can only boot stock roms with the speedmod kernel other kernels give bootloop.
Ugh this is pretty frustrating, will try to downgrade to xxki3.
Btw, after i flashed Cm7 twice my phone bootloops, then when i flash a CWM kernel to boot in recovery mode i get Can't mount /cache/blabla. really weird, i have never seen this on a phone ! =)
Yay its working!! downgraded to XWKI4 and flashed the cwm kernel! now im running CM7! thx peeps! =)
For the other people that had problems, you have to flash the codeworkx kernel because cf root kernel has a modified CWM that is not compatible withCM7
i have almost the same problem,but me i can flash any rom,but the problem is with the kernel my phone refuses to boot on any other kernel else than cf-root and the speedmod,it freezes in the kernel loading so i must turn it off and reflash via odin cf-root or speedmod to get it works again.

Yes, its all the same problem, flashing a rom with a diff kernel won't boot up, will just be stuck on boot logo...
---------- Post added at 12:24 PM ---------- Previous post was at 12:24 PM ----------
Phew! NOW I HAVE CM7 RUNNING ON MY PHONE!!
I'm gonna try to explain how i fixed my issue, as clear and explanatory as i can..
lucky i didn't brick my phone during all this, because I tried so many things and none worked.I unsuccessfully tried downgrading to XWkI4, ZCKI4, and alot others via Odin... after flashing all i get is tons of error messages(on 3e recorvery) E: can't open/cache or E:failed blah bla bla to load /efs... i thought OMG! my phone is bricked! then i recalled reading somewhere that flashing the 3 tar (PDA,MODEM,CSC) files usually should work(maybe better than flashing a 1 tar file), so i found a 3 files xxKI3 rom, flashed it and BAM! it booted up this time without any error. so now i went ahead and rooted it since the tar files came unrooted, then went into CWM to flash cm7 ROM, flashed it twice and ofc i got stuck on boot logo.....i didn't panic much, i pulled out the battery, and restarted to CWM where i cleared cache/ dalvik/ and did wipe/factory reset, then i reflashed CM7 again (twice) and it worked!!!! YES, CM7 is fiannly working on my SG2!
thanks for everyone for helping, and i hope this can help others in same boat as me..

[Q] Kernel Panic with Many ROMs.

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?

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.

[Q] Flashing white screen on boot

hi guys, first post
ive had my rooted galaxy s2 with the latest siyah kernel 3.3.2, i had cwm recover 5 and rom manager
i tried to flash cyanogen mod through rom manager, following the steps it gave me, i downloaded the files through rom manager and went through all the prompts till i clicked agee to go into recovery mode.
once it did that the phone shut off but would not turn on again so i went to turn on manually, it loads the samsung galaxy screen with the yellow triangle but goes straight into a white flashing screen.
Ive tried taking the battery out, leaving it and putting it back in again, still a flashing screen,
check what i9100 you have and download correct cm9.
using cwm format data system cacha sdcard dalvik
flash cm9 using cwm
rommanager doesnt work on GS2

Try flashing a kernel first, and if that doesn't work, flash a rom in Odin, re-root your phone & restore your backup. But yeah, don't use Rom Manager with a kernel that has CWRecovery. One or the other. Rom Manager has a habit of doing stuff like what's happened to you on SGS2's which also have CWRecovery installed.

awesome, I tried flashing the latest siyah kernel, the one that i already had on my phone before the problems, that didn't do anything to get me through, any suggestions on which kernel/rom to flash?
because you are on siyah and im not comfortable with that, please flash a stock kernel or cfroot kernel and format system data partitions after that.
now flash any official stock ICS or GB rom using Odin.

ohh sweet baby jesus im i flashed a cf kernel and now im into cwm on 4.0.1.5, can i just normal reboot my phone now?
No need to format anything. Given you want to use CM9, I'd recommend you flash CM9 Resurrection Edition in Odin, put the latest CM9 nightly & Gapps on your internal/external SD card then flash that nightly & Gapps in CWM (read the first page of the CM9 discussion thread thoroughly & follow the instructions to the letter. From there you can stick with the CM9 stock kernel or flash whatever other kernel you want to use (provided it's CM9 compatible).
From then on, if you want to flash CM9 nightlies, do it via CWM/CWRecovery, just don't use Rom Manager this time I use CM9 as well & I have it frozen because I use Siyah (which has CWM).

alrighty! thanks for the info, is cf kernel compatible with cm9? i want to just have one kernel that'll handle most roms, any suggestions?
ive reloaded my old stable phone version, the version i saved before trying to flash cyanogen mod with rom manager, this version has siyah and stock rom, back to square one *phew*
i still say wipe first, cm9 will come with its own latest cwm that can be used to flash any custom roms after.
flashing via odin version is easy and fool proof as it has everything bundled for correct working of cm9.
If you flash CM9 the CM9 kernel will overwrite/replace your CFRoot kernel, which is fine. As I said in my previous post you can stick with that if you're happy with it, or you can flash any other kernel that's CM9 compatible.
No suggestions/recommendations. Because your experience will not be the same as someone else's using a given rom or kernel. If you want to go down that path, try some kernels to find one you like. To see if a kernel is compatible with CM9, read the the dev thread devoted to the kernel in question.
OK. Given you're back @ square one, Atifsh is right when he says flashing the Resurrection version (Odin version) then flashing Gapps/nightly from there is probably a good way to go for you. Once you've done that, you'll be able to flash CM9 nightlies via CWRecovery. As said previously, read that first page of the CM9 discussion thread/instructions thoroughly before you do anything.

Something similar happened to me too. I flashed stock XWLPG, then siyah 3.3.2 and did a factory reset. After that, got stuck in a flashing white screen after the yellow triangle.
What I did: boot on download mode, flash XWLPG over PC Odin once more, did a full wipe BEFORE flashing siyah and then siyah. Everything went ok this time, but eventually I found out that every time I do a factory reset after siyah that problem would occur.

My s2 won't boot any custom roms

Ok before we start, I have looked and tried everything I can find so I will post what I have done after I post my issue. (I know I'm new but I've been using this site a lot lately I just never signed up)
Alright.
My S2 gt-i9100 running ICS 4.0.3 XXLPB
I can root it with cf mod, no problem and confirmed that the root is working properly.
I use CWM recovery. Every single time I've tried to flashboot a custome rom, from Res Remix to straight up cm10 to other jelly bean mods, all the "top" mods suggested in articles, though it says successful, It always, always gets stuck on the Galaxy s2 screen with the yellow triangle. It does not go black, it just stays on that screen, I've left it for as long as 2 hours and it does not do anything and does not let me back into recovery mode. (download mode yes)
I have, multiple times, re-installed stock rom, re-rooted etc...
cleared cache and davik cache, factory reset and format system (prior to flashing the custome roms and sometimes right after as some suggest)
I even tried a complete wipe of the sd card, system, then reflashed stock rom. It always works to return to stock rom and to root it, but nothing else. It seems every solution I find on this site, and many others are point to the above things I have tried all with a slight variety. I have tried many different custom roms,
I'm lost what to do next? I can't find any other information, my binary count is up to 18 now and none of it has worked.
Which kernel are you using?

I'm sorry, I thought I mentioned all the info I had.
My current kernel version for ICS is 3.0.15-I9100XXLPB
The kernels I have tried when booting res remix are both Dormanx(sp?) and CM10.1, also tried cm10.1 with another rom.
Sorry I added info, not sure which one you wanted

1) re- install stock ICS 4.0.3 rom vide ODIn.
2) use the tar file of siyah kernel v4.1.5 or 5.0.1 to root ur phone vide Odin.
3) now use the siyah kernel v4.1.5/5.0.1 recovery to flash any custom rom of ur choice by fallowing the install instruction of the same carefully

ohh, yes the Siyah kernel, I failed to mention that i tried rooting using the siyah kernel early on and it would get stuck on the boot screen and even ICS wouldn't work. now on the other hand, this was one of my early attempts and i've tried everything else twice so I will try this option again and get back thanks
I have now tried to boot kernel Siyah 5.0.1 twice and it gets stuck on the kernel boot screen after the samsung s2 screen (the one with the yellow triangle) The screen is a ying-yang symbol with pink/purple lighting. I have left it on for 10 minutes and it stays on that screen. I have removed the battery and put it back in and now it doesn't even get past the s2 bootup screen, I left it for a couple minutes, still nothing. Reboot the phone again and now it's in Kernel Panic Upload Mode... Going back to stock rom. I'll try to find a 4.1.5 siyah kernel and try that one and see if it does anything different.

Just tried dorimanx version 7.50, gets stuck on the bootlogo screen, similar to what siyah was doing.
edit: Also tried dorimanx 8.1, same thing.
Edit: Tried dorimanx 8.3, flashed through cwm recovery this time, still does the same thing

hi, i have a problem close to the problem here. i recently soft bricked my phone ,sgs2 gti9100 with jellybean 4.1.2. so i tried installing a custom rom named neatrom. after installation the phone reboots and stays in the flashing android sign. it stays like that until the battery runs out. do you think i should change kernals or flash stock rom?

And don't forget to go in recovery mode and wipe out the dalvik memory under advanced. After wiping dalvik/clearing user data and formatting your phone, reinstall the rom of your choice (that's compatible with the phone)
you can also install siyah 6 and flash kitkat directly from recovery.
Then it would use kitkats kernel and bootup the rom
thank you guys for your replys. i will try what you suggested and get back to you

Unable to install any softwre outside of Odin. Please Help.

[Solved]
I am unable to flash any roms through cwm, and can only do it through odin. Flashing through cwm results in the phone not loading past the boot logo.
I formatted sd card in cwm, thinking it would only restore to factory settings, not knowing it would completely wipe everything.
From then i was unable to even see the boot logo or recovery mode, but luckily download mode still worked.
So i flashed the stock rom through odin, but it still plays up. Now the battery doesn't last more than 1 day, and constantly freezes.
Now whenever i install anything in cwm, as soon as i reboot, it goes to the bootscreen and freezes. I have tried at least 5 different roms and the same story each time, So each time i have to reflash stock rom with odin.
So any ideas to why this is? any help is appreciated. I have tried ultimate kernel wipe cleaner , or whatever it is called as well.
[Solved]
I just reflashed stock ICS in odin, and ticked the 're-partition' box. the repartition file is called " u1_02_20110310_emmc_EXT4.pit ". Now it works good as new and I'm currently running PACman rom on 4.3. gg guys.
Just to check, but you have factory reset after flashing the new ROM from CWM right?
Try these steps :
1. Flash ROMNuke script by hawkerpaul. (it's a ROM nuke, not just a kernel nuke)
2. Flash ROM in CWM.
3. Boot.
I know it sounds simple, but that's got me out of a few odd bootloop /failed flash situations. Give it a go.
Then, if that doesn't work, re-download the ROM which you're attempting to flash & try again.
One more thing, what kernel are you trying to flash the ROM from in CWM? Try a different one, say siyah. I've sometimes seen where a particular kernel won't flash but another will for no apparent reason.

it was stock ics cwm i think?, also another thing when I install a new rom, when it shows the progress bar, it goes up to 3 quarters then it skips the rest and says update completed (I just tried Romnuke and same story). I have also tried siyah kernel and it just freezes at the siyah kernel instead. Im currently stuck on stock ICS 4.0.2
Not sure what you mean by 'stock ICS CWM'?
And just to make sure, you definitely have an i9100 right? Not a variant, i9100g etc? Just asking as 4.0.2 was never released for i9100, only 4.0.3 and 4.0.4 (stay away from that one)
So now, re-download the ROM which you're attempting to flash, and try again after the ROMNuke script. Does the script run successfully? Or does it have errors /messages which indicate it didn't run successfully?

my bad it is 4.0.3, it is definitely only gt-i9100, and in recover mode it says CWM-based Recover v5.0.2.7

All good. And also good that you have an i9100.
Ok, so have you tried the things I said?
1. Try flashing from a different kernel (your choice, try one other than Siyah)
2. Re-download the ROM & reflash with Nuke script then ROM.
[Solved]
5 months later I found the answer when messing with odin. What you do is tick the 're-partition' box, and then in the 'pit' sections you need the partition file i guess, for the i9100 its called u1_02_20110310_emmc_EXT4.pit . hope this helps anyone else who may have this problem
