I'm having a problem and after hours of searching I can't find a way to fix the tablet.
A friend did use the wrong update on the tablet and after that, it will simply doesn't turn on. I already did try to use Power+Volume Up, Power+Volume Up/Down and such and it simply doesn't boot into recovery mode and such.
I did try to use the tool "QPST.2.7.474" and I can find the tablet on a COM, and according to the program, it is on Download. I can't change any thing since it's on Download mode (did use a software to extract the .app of a ROM to have access to the boot/system file to try to send it to the tablet) and I can't do nothing in this case.
I did try to see if the device appears on
adb devices but still doesn't show.
Any ideas how to fix this?
