Hello Petefoth,
thanks for your help. I bought another (damaged) z3c and now i have e 0.10 installed and it is working like a charm so far. Now i need to build up one fully working smartphone with best parts of both. The only thing that i was doing different during the install procedure from linage OS was (https://wiki.lineageos.org/devices/z3c/install):
" * Now tap Wipe ." -> OK
“* Now tap Format Data and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage.” -> NEVER DO THIS ON A SONY!!!
“* Return to the previous menu and tap Advanced Wipe , then select the Cache and System partitions and then Swipe to Wipe .” ->NO NEVER DO THIS ON A SONY!!!>
Instead: Just “SWIPE to Wipe” with default in Wipe Menu of TWRP (twrp 3.3.1) (Never “Advanced Wipe”)
And voila, Sideload /e/ and there you go.
May I help testing something to make z3c to a supported /e/ device?
And how to root /e/ for debugging?
Thanks
