Need Qilive 7 Kernel for V88 Rom (RK3066)

Hello!

I have a "working" stock rom for my mom's tablet, with Android 4.2.2. While it boots, it keeps crashing and rebooting after some minutes of use (like facebook, youtube, etc...).

The thing is: I tried to flash the Oma CM12.1 for V88 (without flashing the Loader, because it's a RK3066 tablet). While it boots and displays as "RK3066" in Driver Manager in Windows, the tablet keeps with the blank screen (Totally Blank, not "Black"). This happens when I don't use other kernel than the ROM itself.

I made the parameter file also, because it's an 4GB tablet (not 8GB like the parameter file from Oma's rom website).

Then I tried some 3.0.36+ kernels:

  • RK30 Kernel 3036 7inch Voyager1 Sumvision
  • RK30 Kernel 3036 528 Ntt
  • RK30 Kernel 3036 E7312 Medion
  • RK30 Kernel 3036 S1s Pipo
  • Stock Kernel (could work, why not xD)

But all of this kernels gave it Black Screen and the tablet doesn't boot.

I reflashed the stock kernel (a dump that I did, I can't find the original stock rom anywhere) and it boots.
Still, I'd like to change the ROM (even if it's still Android 4.2.2, as long as it works good, i'm good).

But preferable i'd like to make it work with CM 12.1

 

Oma you'd be a life safer if you could help me!

 

Best regards.

 

PS: I've attached the kernel.img and the parameter file. If you need anything else, just ask.

Thank you for answering!
I tried to flash the kernel.img that I uploaded and it worked. Maybe it uses the kernel from boot.img instead, you must know better than me this things

Anyway, I've attached the boot.img and the recovery.img

Here is the kernel #21 preempt 27 March 2014: http://crewrktablets.arctablet.com/?wpfb_dl=2979

Can I also have a dmesg and a logcat log from the running stock firmware?

Sure, i've attached.

Should I test that kernel with the 5.1 rom?

Regards

Sorry, couldn't edit and upload the post (dunno why, saying url was invalid)

So if you can merge to prevent me from double posting, that would be good

So I tried that kernel, and it showed off the recovery! Before was all white, now it shows the screen.

But when I try to reboot or to factory reset, this error shows up:

16244532_717136185115393_2011233671_n.jpgImage Enlarger

 

Maybe it's my parameter file.

I've attached the stock parameter and the one that I made. The cmdline.txt is in the post before this one.
This tablet only has around 2GB of internal free memory (I think it's less) and the whole memory should be 4GB.

So I tested that parameter file and I can't flash the rom using it.

The other two parameter files that I posted worked, but that doesn't.

I've attached the logs

Yeah, can't work. After re-read your dmesg I can tell you this is NOT a RK3066 tab.

<6>[    0.037995] CPU: Testing write buffer coherency: ok
<4>[    0.124212] CPU1: Booted secondary processor
<4>[    0.164202] CPU2: Booted secondary processor
<4>[    0.204200] CPU3: Booted secondary processor
<6>[    0.204241] Brought up 4 CPUs

Your tab has a RK3188 architecture.

<5>[ 3.431416] 0x000010000000-0x000010400000 : "metadata"

Also the metadata partiton indicates the kernel has selinux on. So, with this kernel you are trapped running customer builds.

So, theres nothing I can do? Not even just changing the system partition with another rom as your 4.2.2 JB?

I would be happy to use your 4.2.2 rom if it works with this kernel.
