I would like to install TWRP on an encrypted device to make a backup and maybe reinstall firmware. (Samsung SMT-530) The reason I wanna do this is because when restarting, I am able to enter password to decrypt but will get stuck in subsequent samsung logo screen forever, without giving me chance to unlock device. And after some googleing the solution seems to be installing twrp and update firmware. The source for this solution says clearly that doing so will wipe out the device, and recommends to backup first. And I thought, and this probably will sound silly, I could make a backup via TWRP.

When trying to go into recovery mode, and install TWRP from sd card gives the following errors. First screenshot is after going into recovery mode, second is error messages after trying to install twrp from sd card First 6 red lines of text after entering recovery mode

last screenshot with error messages after trying to install TWRP from sd card

Most probably this is a silly question, but could please anyone tell me whether it is possible to install TWRP recovery and make a complete backup without having to wipe out - Factory Reset my device ? USB debugging is off device is unrooted and have tried to find clear info via google without success.

  • be careful ... you could brick your device. First do not try to install TWRP - instead go into encrypted Android as usual like before. Then make a factory reset (after you have made a backup). When finish you could try to install TWRP as boot-manager with help of your Linux PC or Linux Laptop. (by your attempts before, this is all failing because filesystem is encrypted) ... you would need to make a factory reset first to install TWRP as boot-manager. – dschinn1001 Mar 15 at 23:51
