I have a bit of a problem with my recovery from my desire 500 single sim. I have unlocked the bootloader and installed first cwr. I tried to install a custom rom, but i couldn't because it said E:Unable to mount '/system. I then switched to TWRP. I again tried to install the same custom rom but i received the same error. I also cannot check the box with system in the mount section. Furthermore, now i cannot change the TWRP back to CWR. And now I cannot do anything with this recovery, but the phone works. I cannot uderstand how.
Do you think you have some idea about what happend or what to do?
Check your recovery and your hboot version....
