Reflashed AOSP 4.2.2 and still had rotation artifacts (before screen start roatate its black for less than second).

Anyways im using and i really like ur cm10.1 build, battery is fine not worst then in my stock 4.2.2 or even better.

I confused with one thing u said:

"For the KK builds you will need the 3.0.36+ kernel.",

but i have 3.0.36 kernel from my 4.2.2 firmware:

kernel 3.0.36+: kernel #34 preempt 19 Dec 2013 - http://crewrktablets.arctablet.com/?wpfb_dl=2515

so it possible to make kitkat for rk30 to work or not?

I tried already with 3.0.36 kernel and i got checking data failed error during flashing (probably wrong parameter file for 8GB tabls, my is 16GB).

Update.

I managed to run kitkat for rk30, fixed parameter file, used my modified stock 4gb internal parameter and changed system partition size to 1024 and it worked (to modify parameter im using Parameter tools in RK3xxx_Firmware_Tools_5.10.28.00) .

There is something wrong with ur original parameter some values are out of range, you need to look at it ( in your parameter there is only 1gb internal for user, and kitkat discription says internal storage 4gb). After succesfull flash and boot when i figured that there is no way to move some application to internal_sd (no option), so there is only 4gb for application i modiffied parameter again.

This time i tried make unified storage, so i resized( in few tries) userdata in parameter to about 14000+ size, this way after flashing i have all my user availalble as an internal memory and sd card. So ican use all my user memeory about 13,95gb for applications, games etc no need to (and there is no option) move to sd.

In this kitkat rk30 build wifi and 3g working for me, i got issue with rotation fliped vertiacly same in camera, i used kylevessPL solution to modify in build prop 2 lines to this: "ro.sf.fakerotation=true" and "ro.sf.hwrotation=270" and this worked.

There is some screen glitch issue, found somwhere dolution to check Disable HW overlays in Developer options but in some games to see some intros etc i had to uncheck this option. Used xposed module to Nomoreoverlay to check this option automaticaly after reboot. Also had to use Kitkat SD Card full access module (known issue with kitkat).

So basically not working only bluetooth and i didnt check hdmi still dont have right cable and i can live without bluetooth.

If u know easy and fast fix it will be awesome.

By the way this rk30 kitkat build has nice antutu bench scores for my tab like 20700+.

After succesfully kitkat flash i tried also few other builds for rk3188 with RK30xxLoader(L)_V1.34 ofc. Tried Odys_Iron_CM11_4.4.4 with 160dpi fix it worked with few issues ofc no rotation and not workin wifi etc, tried also RK31_LoliPop_5.0 and wifi worked, no rotation etc but it looks like nice build as an alpha.

Thanks again for ur awesome work.

Since Oma not showing in this forum for month or so i tried learn stuff, looking in other forums etc to fix problems i encountered using Oma's and RKCrew Roms.

So i started using ubuntu, splited kernels from stock firmwares 4.1.1_2013.07.14 and 4.2.2_2014.03.31. I figured that not need special fixes/recompiling or something for kernels to work with Oma's roms. Just need standalone working kernel.

In my tabs firmware are kernels in boot image, so needed to split them using split_booting_pl command in linux or just use Poverony's RK3xxx_firmware_tools than kernel need to be "signed" using rkcrc -k in linux.

Currently im using Odys IRON CrewRKTablets KK 4.4.2 v1.2 and managed to fix all issues i had like not working wifi, rotation turned, dpi ofc, and damn camera roated to left, but in previous version it worked good. For camera (somone can use this info) need to replace '/system/lib/libcameraservice.so' with one from previous version KK 4.4.2 v1.1 or Rk30 kitkat rom.

Currently im trying figure out how make 3G work in Odys_Iron_Omni_.4.4.4_v1.4 rom, so if it is possible Oma can You throw me some ideas? Thank You and others from RKCrew for awesome roms and waiting for more.
