Notes about Battery Saver script

Can be used with stock or custom kernels
It completely eliminates the need for SetCPU or Overclock Widget
Easily customizable if you use a text editor(scripts located in /system/etc/init.d)
It will set Max/Min CPU speed to 216MHz when a sleep
If SetCPU or Overclock Widget are detected, the script is ignored, so it will not affect them
Preset profiles are:
1.2GHz(when OC kernel is available) - 100-90%
1.0GHz - 89-51%
912MHz - 50-16%
816MHz - 15-0%


v1.1
Switched to a tweaked stock TnT #16 kernel
Tweaked Battery Saver script
Tweaked a couple misc files
Fixed Flash Player to work with Hulu


Important Notes - Due to how this ROM is setup, a wipe is recommended BEFORE flashing (I recommend using my Format ALL zip attached)

Be sure to do a backup before flashing and read the change log

Just a quick question...since this is based on 3991, it's probably not going to need the TNT enhancement pack since VS incorporated most XDA gTab fixes in that release, right? Just a curiosity thing...I wasn't planning on installing it at first, but maybe later down the road to test...thanks for everything you do :)

Its a good rom, but titanium is not working with it, keeps fc.

There is a bug with the contacts also, it has some white lines under sme of them, if not most.

Well, aside from it powering down when I put it in sleep mode about an hour ago, very nice ROM...it's extremely responsive, snappy, and I love the boot animation, although it's kinda decieving, lol. You have a sort of honeycomb looking boot animation and even though I knew it wasn't honeycomb I started getting excited, lol. Great ROM yet again calkulin. Thanks :)

    Ok ROM is up...

    I cant select thumb keyboard either. You're not alone.

    Just move the APK of your keyboard from data/app to system/app and reboot, you will need to use root explorer or anything that can play in the system partition.

    This is a well know issue for a couple of rom based on T&T

    In this rom and others I have been having an issue with the tab not waking back up after going to sleep. Pershoots new kernel seems to have resolved the issue and can be found on his site, here is a link

    New version with change log is up.....
