Installation
This assumes you have installed TWRP. You cannot use custom firmware if you have updated to stock firmware newer than T290XXU3CVG3. See the disclaimer here |
For Android to work again, you will need to flash the stock recovery and wipe Data from there. If not, Android gets stuck on the bootanimation. |
Run pmbootstrap install
, then pmbootstrap export.
Transfer the exported files to the device using your preferred method. (e.g. microSD, USB OTG, adb push
)
Start TWRP and do the following
- Wipe System and Data partitions.
- Flash
boot.img
to Boot. - Go to Advanced > Terminal and run
dd if=samsung-gtowifi.img of=/dev/block/mmcblk0p69
and be patient. Make sure you adapt the input file to wherever you copied it to. - Reboot. TWRP will warn you saying "No OS is installed!", you can ignore this.
/dev/block/mmcblk0p69
is the data partition, do not misspell this when installing or you may brick your device.
