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 |
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. Do not misspell the output file, or you will overwrite another partition and possibly brick the device. - Reboot. TWRP will warn you saying "No OS is installed!", you can ignore this.
Notes
If you are using LightDM and the desktop doesn't start (splash screen simply freezes after 2-4 minutes of loading), disable logind-check-graphical in the LightDM configuration
nm-applet
doesn't create connection profiles properly. You have to use nm-cli
whenever you connect to a new network for the first time
