25. HOWEVER – seems via File Manager I could not see any files, they were all encrypted. The camera couldn’t take any pictures as it prompted "insert sd card before using camera". So I now realised you must Format Data in TWRP…..so booted back to TWRP and via the Wipe menu, chose Format Data and typed “yes” to continue. Once complete, via TWRP I rebooted back to recovery.
