TWRP recovery is very good. You can copy any version of ROM updates (a single .zip file) to a memory card and install it from TWRP recovery. So, use the Rootjoy app for only downloading a ROM, then copy the file to your memory card. While TWRP recovery is running, you even can copy the file to the internal memory and install from there. You just need to mount the internal memory and enable MTP. |
