[GUIDE] How to Install a Custom Recovery Using Terminal Emulator
I couldn't be bothered with learning ADB, but wanted a custom recovery on my SIII ... maybe you can relate?
Here's the easiest way to do it -- and you don't even need a computer!!! You do, however, already need to be rooted before you can use this method ...
Download your recovery of choice (.. as of this writing, I think there are two: CWM and TWRP ..) and make sure you place a copy in the root drive of your sdcard. Rename it recovery.img, if you want to follow the terminal directions listed below ...
Then, download a terminal emulator onto your device (I use Better Terminal Emulator Pro, which is a paid app) and fire it up.
Once in the terminal emulator, type the following commands one line at a time, waiting after each line for the appropriate prompt:
# dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p18
# reboot recovery
Your device should then boot into the custom recovery, which serves as immediate confirmation that you did things correctly.
I just used this method to install birdman's twrp8.img to my SIII and it worked like a charm.
