[SOLVED] So, I think I may have bricked my tablet in some way...


Hello,

I decided to try flashing a new ROM onto my Momo 12 for the first time, but because of being a newbie to flashing tablets/RK3066 devices, the instructions here and on the download page for that ROM didn't really help me. I managed to get the tablet into flash mode and do Erase IDB, and then when I clicked Run on RKAndroidTool to flash the .img files it seemed to all be going fine, but whilst system.img was flashing I got the errors: Download file failed, and Run failed.

This might have been because I didn't add and tick the loader file? I have no idea really.

So now when I try to flash it again, my tablet won't stay connected in flash mode, it disconnects again after 5 or 6 seconds. I have tried the method of pressing volume down and then plugging in the usb before holding down the power button as well, I have also removed the usb drivers with USBDeview and reinstalled them, I've tried flashing using another PC too, using the Switch button on RKAndroidTool I get the message "Device can not do switch, because it is not msc device." and my tablet now does not boot at all.

I can get it into mask rom mode by shorting pins 8 & 9 on one of the NAND chips, but still it disconnects too fast for me to flash anything.

These are the logs from when I try to reflash my tablet in mask rom mode:

My tablet was playing nice today and actually stayed connected. I did Erase IDB again and clicked Run, something was flashed but it failed the data check afterwards.

Another log from RKAndroidTool:

Could there be something wrong with the system.img file I'm trying to use? since that's where it failed last time something was being flashed as well.


EDIT: Well it seems I'm lucky today, I tried flashing the ROM I originally had (Ployer Momo 12 TNT Release 2) with Rockchip Batch Tool and it worked... tablet turns on and works fine. All I can think of that I did differently was holding the power button for 10 seconds whilst unplugged from the PC (tried that before and it didn't help) and then plugging it back in whilst also on charge with the DC plug. Maybe someone will find that helpful if having a similar problem, I'm glad I kept trying! haha
