You assume the risk this or any modification could possibly brick your tablet Ok from what I have read some of you guys have upside down screens, this usually can be fixed via MBR, aka bootloader. You need adb setup and working if you have a filemanger that has root access this would be great. anyway download bootloader files. 9742_BOOTLOADER.ZIP extract some where, on your sdcard would be nice. if you want to use file manger. adb shell mkdir /sdcard/na mount -t vfat /dev/block/nanda /sdcard/na exit if you placed the files on sdcard, and have file manger with root access, navigate file manger to /sdcard/na/ delete script0.bin and script.bin then navigate to /sdcard/na/linux and delete u-boot.bin. then use file manager and copy the script0.bin and script.bin you downloaded to /sdcard/na/ and copy the u-boot.bin you download to /sdcard/na/linux you are just replacing 3 files. if you want to do via adb you can skip the file manager stuff and just push the files. adb push script0.bin /sdcard/na/ adb push script.bin /sdcard/na/ adb push u-boot.bin /sdcard/na/linux in either case reboot. Do not reboot until you have copied each of the 3 files to where they need to go, if using file manger do a dry run make sure you can find the files that need to be replaced, and where they go before doing anything.
