Wow,
I flashed 2017.10.11 FW ( with OTA enabled ) on 2017.11.22 BT FW without loosing :
- TWRP Recovery
- personal apps & related data
- content of internal memory
Of course, the purpose was to obtain new OTA updates. Watch finds, in 2 steps, 2 wireless updates :
- 2018.02.06
- 2018.03.13
and of course flashing first one of these 2 updates involves loosing TWRP Recovery, I supposed that Anyway are still maintained :
- personal apps & related data
- content of internal memory
Now I’ve only to flash over TWRP and SuperSU again. That’s all done
PS With SP Flash Tool 5.17.44
