Known problems with this port
- On LightDM, the desktop won't work until you disable
logind-check-graphical
in/etc/lightdm/lightdm.conf
. (see Display manager#CanGraphical_issue) - Battery capacity doesn't update.
- Device now kernel panics when connected to USB. Likely related to USB networking.
Download mode
- Turn off the device.
- Plug in a USB A to Micro-USB Data cable from a PC to the tablet while holding down both volume up and down buttons, releasing the buttons when the screen turns on.
- If you are met with a blue screen, press the volume up button. If not, reboot and try again.
Volume up is the button closest to Power
Installation
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.
For Android to work again, you will need to flash stock firmware and wipe Data via (stock) recovery. If not, or if you try to use TWRP, Android gets stuck on the boot animation. |
