howto rock with CM10.1 by crewrktablets if yu have a Mediacom 810c or PMP5080B or BQKEPLER.

1) Download  theRom cm10.1 1.2.4 from: http://crewrktablets.arctablet.com/?wpfb_dl=1300

Flash it but you have to use this files, instead of original ones :

a) this Paramters file: Zippyshare.com - parameter422
b) this Boot.img : Zippyshare.com - boot.img
3) this kernel.img  : Zippyshare.com - CM10_kernel.img

After flashing the rom, reboot in recovery and run this scripts:

Format Nand zip : http://crewrktablets.arctablet.com/?wpfb_dl=635
Service jar Fix (iVery importatnt to avoid Bootloops): Zippyshare.com - CrewRKTablets_CM10.1_124_service_fix.zip
USB Bluetooth Support Patch: http://crewrktablets.arctablet.com/?wpfb_dl=1311
Zram Support patch: http://crewrktablets.arctablet.com/?wpfb_dl=1388

Xteam has made a new kernel for cm10.1 by crewrktablets with :

USB CSR Bluetooth Support
Zram Support (you have to enable it in developer settings)
KSM Support (you have to enable it in developer settings)
Fix camera and e Rotation

regards,
Xteam

Hello again!

I decided to give this one a go, but although i did the steps exactly as you said, tablet boots to recovery and after 2 seconds shows this -

photo0020.jpgImage Enlarger

and i can only reset it with the needle... it happens every time i use xteam kernel on any rom that isn't theirs

Thanks in advance!

uhm,

 it seems a cpu freq related question. What is your tab ?

Xteam kernel is Ovecocket up to 1,2 GHz. Your cpu does not suppor high freqs....

 

In Xteam's rom the boot.img set the max freq at 1008 MHz at boot, also in the recovery, but in this rom.

Try to flash the kernel made by Jokenkauz for Odys NeoX8, then boot into recovery and flash al the zip as described in the release notes.

After that, reboot and let the rom starts...  the in developer options, set the max CPU freq at 1008. Remembet to flag the box (apply at boot).

Now, you can shutdown the tab and flash the Xteam Kernel form this CM10.1

 

Cheers,

  Yatto.

If i do everything like that, tablet boots fine but after ~30sec. happens this from the picture. in those 30sec i managed to see that min freq. is 204mhz, max freq. is 1008mhz, which is fine. Tablet is Prestigio PMP5080B. Thanks!

Ok, managed to get it working.

 

The fact is that you mustn't use the frequency of 204mhz. Set the min to 300 and max at 1008 mhz when you're using neox8 kernel, flag to set on boot, shutdown tab and flash xteam kernel. All ok now... :)

Thanks, for the feedback.

In Xteam's Rom in the boot.img we set the max cpu to 1008 and the min cpu to 600, for the tabs that don't support lower and higher freqs.

http://www60.zippyshare.com/v/61866389/file.html

At this link a boot.img with cpu freqs settings, on early init. 

 

Remember to activate the KSM and ZRAM in developer settings....

 

Post your feedback.

Hi yatto

 

Is it possible to make kernel for prestigio pmp5080c pro?, i can run it with xteam kernel but missing 500 mb RAM and accelerometer. With crewrktablets kernel for bq-kepler2 ewerything is ok, but cant get bluetooth runing(tried ewerything - with xteam kernel works fine). If you have time and is not much trouble...

 

Thanks in advance

Sorry I can't compile kernel for Kepler2/pmp5080pro, starting from my source..... I can try to add 512MB ram to xteam kernel....  but you must wait some days...

thanks yatto

as i said if it is not much trouble for you, ok adding 512mb and kernel driver for accelerometer would be fine if you consider it could work if not - never mind. I didnt mean it to compile new kernel, just presumed that you might have your kernel mounted in virtual maschine (read little bit about kernels, but still end user) and it wouldnt be to much work ,so we can give it try.

http://www55.zippyshare.com/v/80156806/file.html

Here there is a Kernel with 1024 MB ram and mma7660 gsensor driver.

Test it and make me some screenshot with system ram...

This is a test kernel, I made some mods to kernel framebuffer, display video and backlight drivers, that are backported from 3.0.36 kernel for rockchip 3188.  There are mirroring and dual display drivers, but i haven't tested them.

Let me know how is the battery drain....  Ii wait for your feedback !

Cheers....

I have 5080cpro and with this karnel yatto gives (kepler2) ram is 1024, external SD ok, rotation not working or is upside down, no battery stats and battery accuracy, 1,2ghz one frezze coz i didnt set clocks.

One more BUG i forgot : after sleep display is dimmed until under settings adjust brightness (just touch and brightness return to normal).

With karnel on http://crewrktablets.arctablet.com/%3Fp%3D3143&usg=ALkJrhj5LnOXJila6MC-vt4abpe7IVauoA external SD as internal mem, no autorotation or batt stats.

I try several karnels (loox,810c..) all have some fault but CM10.1 works! (I was applying all zip fixes after flashing).

Waiting for update :)

We are little bit of the topic here, but i hope they will forgive us.

Here is kernel http://crewrktablets.arctablet.com/?wpfb_dl=1379, than http://crewrktablets.arctablet.com/?wpfb_dl=635, than sensor fix http://crewrktablets.arctablet.com/?wpfb_dl=972, zram fix http://crewrktablets.arctablet.com/?wpfb_dl=1388, and if you want internal sd mounted as nand http://crewrktablets.arctablet.com/?wpfb_dl=327 .That should work on pmp5080cpro

good luck

Hi Yatto

Sorry to keep you waiting but everyone deserves little bit rest after holidays.

So flashed your kernel and boot img., left original parameters file than nand fix and just rebooted. it goes to bootloop so installed your services.jar- boots ok. Display is upside down(mirrored), but graphics work fine and rotation is ok. RAM is 795 mb, with kepler kernel is 802 mb. Than i installed zram and bluetooth fixes, zram and ksm works ok, but bluetooth conected and paired with phone only once(still note in my phone "Rockchip based tablet" paired) and i cant get it to work anymore (turned everything upside down, wiped out, reinstalled...). CPU is runing at1200 mhz while booting but system freezes later on, so made gov.script in init.d with max speed 1104 mhz. It doesn't work on boot(cant control gov. with script in init.d?), but if I run the script when system is up and running than it works ok.CPU cant run on freq. higher than 1104 mhz. Battery is on some sort of "turbo charge and discharge" missing accuracy definitly and if it is full and hdmi connected freezes whole system(while hdmi connected and battery charging there is an issue on this tablet with all custom roms and kernels so far). Did some antutu benchmarks(to compare kernels - with results nearly same) - results range 4300 to 4800. That's all about it so far. I am going to try and reinstall everything just to check if i can get bluetooth runing, usb tool apk shows that bluetooth is connected but i cant switch it on.
