Incredible this is the extra boot my tablet needs, i'm using kasper's omni rom and it has always been extremely smooth, now with a lower ram usage and some tweaks, it's even better ! thank you!

i installed this kernal and can no longer get root. Are you having this problem. I am on kaspers Omni rom as well.

I had the same issue and had to re-flash the rom. Looking at the file, it looks to be for CM based rome only.

Most if not all modern aosp Roms like aokp, pacman, and others use the same kernel source. I am using a cm10.2 based rom on my tablet but, a kernel should not effect superuser. What errors are you getting? Have you tried updating Superuser or supersu which ever one is installed?

 

[Dreameagl]

When I tried to run Titanium Backup, but it kept telling me that it did not have root.
I tried installing and updating each of the Superuser and SuperSU separately without success. When I re-flashed the PAC 4.3 rom, things went back to normal.

How about for P7500?

Is there a kernel like this for P7500?

I could make one. Just will need a willing tester.

Nope, i have no issues at all, flashed it and works perfect since day one, still using same ROM and this kernel, it's just perfect for me like it is now

I think I must have had some other issue. I had to do a wipe and re install and now everything works great.

Why? Just flash it. It works perfectly fine for me. No root issues at all.

So the version I posted last night for the 7500 is all good? There really is no reason it wouldn't be just needed confirmation.

What difference did you see after you flashed? is it better than one packed with from bee_gee's ROM?
