Hello everyone

I have old no name tablet Kiano Core 10.1 Dual 3G - ARM Cortex A9 rk3066 dual processor, 16gb, 1gb ram, resolution 1280x800 (10.1'ofc), Mali400MP4, android 4.2.2 (kernel 3.0.36+) stock firmware with working CWM 6.0.3.1 and unofficial TWRP 2.7.0.0, tab is rooted ofc.
Im looking for better rom preferably kitkat on rk30 or aosp 4.2.2.
I tried cm10.1, aosp 4.2.2, but no success, not entering to cwm or when i used generic recovery, tablet didnt boot just black screen. I got some success using momo 12 kernel(momo 12 is almost same spec like my tab) and generic recovery, so aosp 4.2.2 worked for me with some momo 12 kernel issue ofc (rotation turned 90degree left, no sound but wifi worked, touch worked ofc).
Tried also rk30 kitkat but i got checking download data failed during flashing, probably something related with parameter file, cuz i switched for RK31_parameter_kernel_12mb file and flash was ok. But still didnt boot to recovery (tried also generic one) or didnt boot system (just black screen).
There is some issue with my kernels, i have 4.1.1 firmware and 4.2.2 and in both kernels are located in boot.img (i got kernels from cwm backup or dumped form stock firmware). Kernel size is 12mb for 4.2.2 and about 8mb for 4.1.1.

There is some links:
logs from my stock 4.2.2: logcat.log, dmesg.log
and link to my 4.2.2 firmware and 4.1.1 firmware
Oma, i know u are probably very busy, but can u look at it to make kernel work with kitkat or aosp 4.2.2 please?

Thanks for all your help Oma.
First i tried rk30 kitkat build same failed messege -checking data failed during flashing (something related with parameter), i tried my 4.2.2 parameter i sucessfully flashed but stuck on logo. Took me ahile to enter to bootloader mode.
Than i tried A.O.S.P 4.2.2 with 3.0.8+ kernel and it worked but ofc i had to use generic recovery, and after first boot i just flashed my working TWRP 2.7.0.0 (parameter and recovery ticked only). Installed some zips in recovery format_NAND_fix,YouTube fix v3.4, intSD_to_NAND, TabletUI.
Seams all things i checked work, touch work, sensor(still some rotation artefacts) works, wifi works, 3g works i did antutu bench and i got like 19600+ same like in my 4.2.2 official build. Later ill try cm10.1 build u recomended( it should work thou) cuz it seams more polished (fixed rotation artefacts, etc).

Ihave few questions:

1.Which build has better battery consumption(using less battery) your cm10.1 or aosp4.2.2?

2. Can i use Xposed and its modules with your builds (cm10, aosp)?

3.Whats this battery info fix for? (i can have and i had on stock 4.2.2 some battery info issue, now with aosp seams my battery info is stuck on 76% and still charging- it can change thou)

Anyways Thanks for fixed my tabs kernels, dunno what u did but they working with ur builds now.

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

As for Battery consumption there should be no difference.

Xposed will work with AOSP, with CM builds it will likely crash the build.

Battery info fix is for tabs that works in an other way. Standard works for you obviously.

Ok using now cm10.1 build installed same way like aosp4.2.2, seams all is working nice, atutu bench lower like 14500+ thou.

Fixed rotation artifacts is nice, used few hints from ur blog (batter drain, wifi, ui animations scales etc) and it running smooth. Im gonna test battery for few days.

There is any roatation artefact fix for ur AOSP build ? Aosp is really nice build simple and fast, i would use it for sure with rotation  artefact fix. Found somwhere in this forum 2 files named "CrewRKTablets_RK30_CM10.1_boot.img_rotation artefacts fix" and "CrewRKTablets_RK30_CM10.1_rotation artefacts fix" it is fix for cm10 earlier version like 1.3.5, it will work with AOSP ?

Anyways u can add my tab to tabs list confirmed installation tabs for cm10 and aosp (with 3.0.8 kernel ofc).

Fine. The AOSP builds never had rotation artefacts. Do you use build v3.4?

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.

I found newest stock firmware for my tab:

4.1.1_2013.07.14

4.2.2_2014.03.31

There are some kernel improvement, im sure there is at least one diffrent revision for my tab.

Please make working kernels as earlier.

I hope u will back and post again in this forum.

Update.

Tried fix bluetooth issue in rk30 kitkat build, installed zip in TWRP with system\vendor\lib\libbt-vendor.so file update from my stock 4.2.2, but didnt worked. Finnaly fixed it installing Bluetooth.apk from ur 4.4.4 omni build and using Titanium Backup transformed it to system app.

I got other success i tried rk3188 Odys_Iron_Omni_.4.4.4_v1.4.1 flashed without loader, i used dpi 160, and v88 rotation fix and managed to find in other topics how fix 2 other issues i got and fixed wifi and bluetooth(used metod i tied for rk30 kitkat it worked). I had some strange visual rotation glitch, i fixed it using previous build 1.4. I didnt find solution how to fix not working modem 3G. Any tips which files i should replace etc?

I succeded also flash ur Odys Iron CM11 4.4.4 v1.2, used 160dpi fix found solution among fixes for other  models to fix wifi and bluetooth, rotation etc. Still didnt manage to 3g work same like in omni 4.4.4 build. Really i had no idea wher to looking for solution.

Thanks again for Your 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.
