custom kernels wont take

[DaUsedMCR]

No custom kernels will work on my s3. I boot into recovery, flash the kernel, then wipe cache and dalvik right? Every time i try one (most recently with cm10 and kt747) i just get a black screen and the phone becomes unresponsive except for the menu and back lights. I have to battery pull and nandroid restore each time. Am i doing something wrong? I used to flash kernels all the time on my evo 4g...

The directions for kt747 say to fix permissions after you wipe cache and dalvik. Did you do that?

Is that kernal compatible with Wicked z sensations?

 

[gilbequick]

Is it overclockable?

 

[DaUsedMCR]

Yeah I tried that too with no dice. The only kernel that has worked for me was trinity kernel on blazer ICS. Other than that no jb kernels will work. I tried kt747 with ICS too with no go and kt747 with cm10 m2. Are there other aosp job kernels I cold try?

All phones are not created equally. Kernels are not dependent on roms. They are dependent on the phone. Some phones run kernels better than others. Some won't run any custom kernels and some will run anything you throw at it... perhaps you got unlucky with a dud.

Are you on the LJ7 firmware?

Also I think with kernels, don't you have to "mount System" in CWM prior to flash for it to take? I'm not sure, it's been a while since I flashed a kernel.

Nope... I've never had to do this. I just flashed the agat JB kernel without a problem. Wipe cache, wiped dalvik and flashed. no problem.....

You have to do the wipe first then flash.

KT's instructions :

Always do the following AFTER installing the kernel:
1. Clear cache
2. Clear dalvik
3. Fix Permissions

KT's instructions :

And I've always been told to always do your wipes first and have never had an issue..

I am paranoid like that, I wipe before and after. Also flash 2x

I use to always do it that way too...but I figure it's best to follow the developers instructions when using his kernel. Whatever works ^^;

I got it working a few days ago. I followed the directions just like I had before, but they are suddenly taking. No idea...
