Good news : I am FINALLY running Sailfish on my Mi 9T EEA now!
I have also found the problem that showed me TWRP Error 7 everytime :
You have bzip2-ed the files in the ROM but TWRP has no bunzip2 which is called by the tar -xz command!
What I ended up doing was :
- Extract the ROM zip file.
- Extract all .bz2 files so that only the .tar file is left.
- Edit all scripts in which those files are mentioned so that only the .tar files are used.
- Compress the ROM back into a zip file.
- Flash with TWRP.
Aaaaand it finally works now!
Thank you soo much for this Jolla Sailfish Custom ROM !!!
I really appreciate it!
