Siyah Kernel Bootloop - Galaxy S III Q&A, Help & Troubleshooting

So like an idiot I used STweaks to OC my Siyah kernel to 1.8Ghz for the pure purpose of seeing what score I got in a benchmark test, a few seconds into the test my kernel crashed and the system rebooted and got stuck in a bootloop. There was no way for me to get out of this not even trying to get into safe mode. The only way I could get round the bootloop was to flash boeffla kernel. I removed Stweaks and Stweaksprofiles and then reflashed Siyah, hoping that would sort it but same bootloop. So reflashed Boeffla and alls good again.
Basically what I would like to know is how to get rid of the changes STweaks made as I would like to use Siyah Kernel again but i don't really want to wipe my phone to do so

siyah folder in the sdcard root

Siyah folder as said, or flash one of the cwm flashable siyah setting zips (themes and apps section)

Thanks
No need to flash anything, I found the .siyah folder and edited the config file manually. Changed the CPU value back down to 1.4Ghz and all works smoothly again, so just wanted to say thanks for all the help

you're welcome. tip for the future: hit thanks to say thanks

[Q] How to overclock the thunderbolt

Hey guys Im currently running DroidTh3ory SHIFTS3NS3 ROM for HTC Thunderbolt. So my question is how do i overclock my phone i heard people overclocking their phone to 1.4ghz and its running smoothly but im stuck on where to go and how do i do it. So any links showing step by step to overclocking would be helpful
If the ROM includes an overclockable kernel with OC slots then it can be set with SetCPU, terminal, or scripts.

If the ROM doesn't include a kernel with OC slots, you can flash another kernel via recovery.

Ok so i flashed the rom i said i flashed and i dont see anything about CPU or tweaking anything, i tried to flash a kernal from the kernal manager in the market but as it was booting up it kept stopping loading stopping loading so i since it was goin pass the loading process i took my battery out went into the recovery and gonna try a different one, any kernal suggestion u think i should flash if you have a direct link would be helpful
Ok I was able to get the setcpu for free thru xda so now from the setcpu idk what im doin, any help

You should be looking at some sliders. Top one is for max CPU clock, bottom one for min CPU clock. Set the bottom one as low as possible, but not so low that the device won't play audio while the screen is off. Don't check the "apply at boot" until you're sure you're stable or else you'll be reflashing your ROM. You can also change your governor. You're average Tbolt should do 1.4GHz easily, but many will do 1.6GHz solidly as well. As long as you don't check "apply at boot", the system will reboot back to defaults if it becomes unstable. If you've got any questions, feel free to PM me.

[Q] Problem with custom kernel?

So i decided to flash back to stock gingerbread (v20a Telus canada) rooted, recovery etc.... but when i attemp to flash a custom kernel all is well until, i get to the lockscreen, everything is all green everywhere, and very very low resolution. im not quite sure what the problem is, i cleared my caches before and after flash also??
> mind tellin what kernel u flashed?
I tried djnoxd kernel and thundervn kernel and they both gave me same problem. Both times I had to restore via backup.
Solved my problem. I had to wipe dalvik-cache manually via root browser in path /data/dalvik-cache/ recovery was not wiping for some odd reason... flashed caf kernel and all is well
Sent from my LG-P500h using XDA
What actually fixes this problem is flashing of.the new gpu libs. And since the caf kernel at the time didn't use these new libs. It worked fine on stock rom

SGS3 Keeps rebooting on lockscreen pls help!

Hi S3 fellow users,
Yesterday i wanted to try some new rom so i flashed Darkys rom with siyah kernel, works fine but flashed back to stock because didnt like the rom, now it reboots itself everytime when its on the lock screen and by itself...
I flashed different stock roms and custom roms with odin for 15times, i wiped everything for 100 times.... dont know what to do? any tips?
I try to flash siyah kernel but that also didnt work.... is there something that can wipe everything and is not a odin flash or a wipe factory from recovery. Please help i need my s3:crying:
Try deleting the initd folder.might be conflicting scripts in that folder..
You'll find in system/etc,delete initd and reboot..
I have no other idea without more info.

Did you do a wipe? Roms don't always transition /data smoothly from one to another.

Yes i did 10 times wipe, i tryd different custom roms, and different stock roms, with odin and with cwm..
Now what i found out is that it only reboots when the screen is off so in lockscreen. if i hold the phone awake it wont reboot,
is there an tool to clean the whole system up? like intitd that i cant found in any way..
How could i delete all the mods that came from other roms? i cant find the initd folder...
My phone is on stock 4.1.1 siyah kernel, rooted, busybox, cwm recovery 6.0.1.2, have root explorer working.
I did wipe/factory reset, dalvik, fix permission, wipe batt stats, wipe cach flashing kernel/rom official and non official
and my phone keeps rebooting when the screen go's off auto or if i pres the power button.
Did you changed CPU voltage or clock settings earlier?
BTW you can remove files with ADB.
1) Boot into recovery
2) Connect USB
3) open ADB shell - 'adb shell'
4) navigate to the folder - 'cd /system/etc/'
5) Remove the files - 'rm -r init.d'
6) exit and reboot phone
Yes i did that early i try 1800 max in stweaks on siyahkernel and then the phone rebooted, dont know exactly what happend then but everything was fine after that... i also used other roms and kernels...
But thanks for your advice i will try to do this, i am new to ADB so i am going to figure that out right now.
is it possible to do that with cwm recovery on it?
That's what the problem is. I did it to my phone once. I overcolocked and undervolt.
Everything worked fine for few mins. But when I rebooted my phone, it went to lock screen and hang for few secs and then reboot again.
Never go to 1800 but a max of 1600. mine max is 1500 now.
Let me gather more info for you.

Oke thanks very much for your help i realy appriciate that! but when i look inside the s tweaks my clock speed is just normal was that for you also?
Did you change any other settings in stweaks, voltage settings?
You can try some different kernel if your phone have problem with siyah.

Guys i there any way to clean every bit of **** that could be on the phone like init.d??? please help
Had same thing happen to me, my fix, 1st save everything to pc from sdcard and titanium backup if you can. Flash stock rom and then put (i use omega v34) on external sdcard. Flash touch recovery. Wipe cache and dalvik, fact reset then go to usb mount and format everything (except external card obviously) then flash omega rom.

I didn't read that you formatted your card before, that wipes any conflicting setting, otherwise might be hardware related.

I just try the exact method you say just to be sure but the same problem remains, i wiped everything that i could but it remains the phone reboots when the screen is off or it dont reboot but it freezes when the screen is off.
I dont think of hardware related problem because when i keep the screen awake i can do whatever i want without problem....

[Q] Siyah kernel profiles?

Im using the latest siyah kernel 7.9 i believe with the latest aokp 4.2.1 rom, and everytime i try to select the performance profile my phone will freeze at some point while booting up. Ive also tried changing to the performance and the extreme performance profiles via Stweaks and when i do my phone freezes immediately afterwards. Ive tried all the usual trouble shooting stuff reinstalled the kernel wipe cache, dalvik etc, same results. Anyone else have this issue? Any advice for a solution would be appreciated. Thanks.

I haven't tried those profiles, but as they are high performance, perhaps they include over clocking? If so, have you run stable over clocked on that ROM previously? Of not, then that might be the issue. Or maybe your phone just doesn't like the governor/scheduler combo in that profile. I get lockups with Pegasus/sio all the time... never worked on my phone no matter what ROM or kernel.

re:
yea my phones always been stable overclocking up to 1400mhz on every rom i've tried. its once i get to 1500mhz is when my phone starts to freeze which is disappointing cuz my last sghi777 s2 was always stable up to 1600mhz. just interested in trying these profiles, still looking for a solution.

I'm going to start with the obvious, did you follow the instructions to reboot into recovery after flashing the kernel before rebooting into the rom and reset the profiles?? It is known to cause havoc with profiles if you don't reset them prior to the first boot. Secondly, any other performance control apps will interfere with stweaks, make sure you don't have aokp's performance control settings set up for set on boot. I personally had issues running siyah with aokp but others have not, for testing purposes you may try another rom temporarily.

yea i followed the directions of the op exactly, i think ive figured out what my problem is now. the max frequency in the performance profile setting is 1500mhz, and my device isnt stable at 1500mhz. although my device doesnt freeze instantly when set at 1500. I'm thinking that is probably part of the problem.

have you cleared the cache and dalvik in recovery + once it boots you need to let it settle down etc.
should be very stable - hope you got your NVFLASH access?
Are you using Hunds kernel ? If you are then use the kernel installer to change to stock kernel and see if it still does it.
If it stops happening then the Hunds kernel sounds like it is not getting enough voltage for your machine. I'm sure I added a voltage fix into the installer when I made it so you would have to go back to Hunds kernel and select that the same time and test.
If you are already on stock kernel I haven't got a clue

The only way I can get it to even work is to have the hunds kernal either normal or data2sd, with or without the voltage fix, it still freezes for 10 sec and tyhen reboots, why???? does anyone know how to help??

Do a fresh install mate. I have never seen anyone with your problem and it definatley should work more stable with the stock kernel. There is no reason for it not to boot with stock kernel installed.
Do a full wipe using the method described in instructions and then reinstall the whole rom with the stock kernel and no voltage fix.
