Hello everyone,

 I have an F&U ETB7858, I flashed with Odys Bravio 4.2.2 and KitKat by Oma, and both worked fine except wi-fi.

So, I tried the Roverpad TRC7 firmware, but it couldn`t boot (white screen). Although when I flashed the Odys`s kernel it booted just fine (except wi-fi). Do you have any kernel to recommend me?

Tablet Hardware:

CPU : rk3026 (2core 1GHz)

RAM: 1G

FLASH NAND 2x4G

Motherboard: MID7856-ver1.3

Display : 1024x768

Wi-fi: rtl8188eu.

I tried a lot of kernels but most of them couldn`t boot.

Thank you!

Every tabs has it's specific kernel. Is the stock firmware available or have you done a backup before playing around?

Unfortunately, I haven`t the stock kernel (my friend  bring it me to me bricked). I also sent an e-mail to F&U asking for the rom, but they say they can`t  sent it.

Are you sure it is RTL8188 wifi? When you use the Odys kernel (change kernel, resource, uboot in folder rockdev/Image) then you should have wifi with the Roverpad build.

Just a question... When I run dmeg it reports Wifi Chip detected : Realtek 8723au.

The above means that my chip is 8723au or the kernel reports it faulty?

Sure, the Odys kernel will report RTL8723 wifi.

I see... Is it possible to see what`s my wifi chip ??? (motherboards chip is to small to read it!). Oh, the USB HOST utility reports 0179:0bda if it helps...

Thank you for the replies...

The ID indicates RTL8188. Try to do a HD foto of the chip.

Yes...I can see it...It says Realtek rtl8188ETV.

I also tried to flash with the Roverpad build with kernel,boot,parameter of Odys, but with no success.

No, that doesn't work. Use the Roverpad build as is. Just change Odys kernel, resource, uboot.

I am sorry but I don`t know how to change resource and uboot...(there is not resource.img in Odys .zip, as for uboot is the parameter and boot.img?)

Sorry, I mixed this up with a rk3126board. It is just the kernel to change in folder rockdev/Image.

Well Roverpad build with odys kernel boots just fine but no wi-fi. But if insmod the 8188eu.ko module then i get wlan0 and wlan1 in netcfg and iwconfig (of course both interfaces are down). I don`t know what this means.

That means the Odys kernel will not support the RTL8188 kernel module (address missmatch). Try to get the genuine firmware.
