Of course, I'll see what can I do when I get everything (OC, UV, ...) working here waiting for a tester...

it is indeed slow. even when completely debloated plus stripped of "essential" system components that I personally do not use. I will try this right away. will report back within an hour in this post.


@Ziyan
it boots, runs, everything seems standard. not seeing any performance increases though. same ol' 10 to 15 fps is there anything more you wish for me to test with it? I replaced this tab a while ago with galaxy note pro 12.2 so I can't really use it enough to check for random reboots
Error 4.0.4 Android Not Found!

Thanks, that's good, it means I can continue improving it. I need to check the kernel periodically after a big bunch of commits, because if something gets broken, it can be hard to find what causes it if from a thousand things I'll push a new version and changelog later today or tomorrow.

Here's a new version. Before testing it, please make some benchmarks with the previous version (mainly 3D), because - if everything works as it should -, the GPU is now working at 520 mhz instead of 416. It should also have CPU overclocking and voltage control support, so please install Trickster Mod, or something like that from Play Store to see if it works (screenshots are welcome). If it works (i'd be a bit surprised lol it was too easy), please run some benchmarks again to see if there's a noticeable difference. I've got 12 pages of commits waiting to be merged, so yeah, if something got broken, I better fix it now

Yeah, antutu will do, just note the invidual points

woah woah... I just went to download the second version and the tab was dead from 77% last night, still warm.

there's a wake problem, screen will turn on one time after booting up but only that one time

and a sleep problem, after manually turning the screen off it will not turn back on (and kills battery very quickly!)
