Hi All,
I have a problem, i made a mistake and flashed a wrong firmware to my Polaroid MID9748 with these specs:
RK3188 1.6Ghz
Retina screen 2048x1536
2MB RAM, 8 GB Storage
BT.
I am able to boot but the touchscreen does not work anymore. I can't do anything.
Can someone help me please ?

Hi Oma,
Stock firmware is not available but I made a backup using your Root And Dump package.
Using the firmware tool (by Sergio Poverony) i rebuild an image based on the backup (boot.img, recovery.img, kernel.img and system.img) and put the command line. Than i reflashed the generated image and VOILA !!
I'm truly happy that i got back my original firmware.
Can you help me to find the right clone of this tablet ?
Best regards,
U.

Hi Oma,
It seems that i miss the user part of my memory 😉 not a problem.
I uploaded the files to mega (kernel.img, boot.img dmesg and command line) here: MID9748.zip
Thanks a lot,

<4>[ 60.158502] MT5931 SDIO WiFi driver (Powered by Rockchip,Ver 3.04) init.
Polaroid MID9748 has MTK5931 wifi.
So, you can use the V88 KK v2.2 build: http://crewrktablets.arctablet.com/?p=2736
Kernel is now in the archive: http://crewrktablets.arctablet.com/?wpfb_dl=2541
Just change kernel in folder rockdev/Images before flash. In CWM install this model fix as a first guess: http://crewrktablets.arctablet.com/?wpfb_dl=1596

Hi Oma,
Just finished installing the given ROM.
I had some problems with my windows 8.1 machine to flash the tablet.
Anyway, I succeeded in flashing the rom using the given kernel, the parameters version for 8Gb ROM and the model fix.
And it seems that everything is working !! Touchscreen, Wifi, BT, audio, seems really great.
Thank you so much.
Best regards,

This morning the tablet was down, not responding to buttons, did a restart, unable to boot to system.
Booting into recovery and resetting user data did the trick. If it happens again, will try to get a logcat and post it here.

Hi Oma,
So after two days of working with this rom, everything is working as expected. No more "application not repsonding" issues like with the original firmware.
My only concern is that the ROM is quite in term of responsiveness, i then tried you RK31 CM10.1.
The UI feels really faster then, like for your 4.4.2, everything is working.
May i ask you if you did a CM11 for these tablets with MTK5931 wifi. I saw CM11 for Odys Iron
Thanks in advance,
Best regards,
U.

Thanks for the quick reply.
Does it mean something for you that the CM10.1 seems more responsive than the 4.4.2 ? Is it expected or is there something strange here ?
In the second case, i can reflash bak the 4.4.2 and dig more.
Best regards,
U.

I do not know how good your stock kernel is ...
To improve UI feeling: disable all animation scales in developer options,
…use Nova launcher and set animation/scroll to “faster than light” and
…enable Entropy Fixer with value 256
