Not cool, I don't have time to play a technician. Even if I flashed as advised what about next updates? Will I have to do it this way every time and wipe phone in the process? This is not comfortable.
A phone wipe (aka factory reset) is highly recommended after each update
, OTA, local or flashed.
This is a good practice on all the Android phones
if you want to avoid issues and to use firmware updates correctly.
Next updates, as always, can also come via OTA, so in this case you won't have to flash your device everytime.
