Hi!
I have an android tablet but I don't know exactly what device it is. Here is everything what I know:
-Brand: Rockchip
-Model: Q8
-Android: 4.2.2 (SDK: 17)
-Kernel: Linux version 3.0.36+ (lijian@ibm-0A) (gcc version 4.6.x-google 20120106 (prerelease) (GCC)) #69 SMP PREEEMPT Thu Jan 16 15:50:05 HKT 2014
-Number of the version of the software: rk3026-eng 4.2.2 JDQ39 eng.lijian.20140107.155201 test-keys
-CPU Model: Rockchips Cortex-A9 (Dual Core, freq: 312-1008MHz)
-Renderer: Mali-400 MP
-Resolution: 800x480
-Rear and front camera: 1,9 MP (1600x1200) and 0,3 MP (640x480)
-Ram: 512MB
-System storage: 0,98GB
-Internal storage: 1,90GB
-GPU version: OpenGL ES 2.0
Also I got some manual with it but there was only "MID Android". Tablet looks like THIS
First I rooted my device with chinese program called Vroot. Then I installed TWRP (I haven't find working CWM for my tablet) and I made backup with it. Then I tried to flash this rom (made by Cash1977) but I didn't flash it with kernel partion so I ended up to a bootloop. Then I tried to restore my TWRP backup but the backup was not proper. The system part size was only 4kt. When I did restore my backup TWRP said "no os installed are you sure you wish to reboot". When I rebooted it ended up to a bootloop again.
Then I flash with Cash's rom and this kernel (3.0.36+ (lijian) #69) and device booted up nicely. Only porblem is now that wifi is not working. I tried also this rom (made by Oma) with same kernel but wifi didn't work.
The issue:Â If I try to turn wifi bar on it will automatic slide to off position. It says that "turning wifi on" but nothing happens. When I go settings>advanced I noticed that mac address is unavailable. Also when I go settings>about tablet>status I found put that imei is unknow.
I guess that I can fix wifi issue if I can find these files FOR MY DEVICE:
- libhardware.so
-Â libhardware_legacy.so
-8188eu.ko
-8188eu.ko.3.0.36+
-8192cu.ko
-8192cu.ko.3.0.36+
-rkwifi.ko
-rkwifi.ko.3.0.36+
-wlan.ko
-wlan.ko.3.0.36+
Another way to fix wifi would be flashing 3.0.8+ kernel to my device because OMA's rom uses 3.0.8+ wifi modules. I don't know where I could find 3.0.8+ kernel for my tablet.
Can anyone help me?

Does the TWRP backup contain the genuine kernel?

Here is the whole backup except data part:Â https://www.dropbox.com/sh/tyocuge5nyaytys/AAC00QmNfmU73T4A4e8idxQfa?dl=0
Sorry but I don't know what genuine kernel means. I'm very new with custom things. Someone also said this when I posted my TWRP backup at XDA:
"what I noticed was that what the boot.img you posted was mounting as system, recovery was mounting as data"
I don't know what that means.

Let me have a dmesg log.
Boot tab fresh and try 2 times to enable/disable wifi. Then do the log.

Yes my tablet is back :). I flash roverpad firmware again and clear IBD and then post dmesg again.
EDIT: I did erase IBD but now I can't flash any files because the parametre files is not working with my device. I used parametre file form roverpad folder
EDIT: I got it working again. I'm now flasing roverpad
EDIT: I can't do proper clean install. When I erase IBD and flash firmware the device doesn't boot up properly. It is booting but even launcher is not working. Only way I can boot up nively after erase IBD is flash boot.img, system.img and kernel.img again.
