I just tried to flash a newer version of TWRP (to be able to write NAND backups on exFAT formatted external SD cards) but after that I could not boot the system. I had to flash a system rom again and restore from titanium backup.
After that - for whatever reason - I had the old version of TWRP recovery installed again..
So, is there any way to update TWRP without getting the same problem again?
Thanks in advance and best,
