Root [Guide] Installing TWRP and making a backup

[bg4m3r]

Finally checked out the video. Nice work bro. What did you use for recording? Also what did you use for audio sync/editing?

Thanks. Used SCR and another phone (old Droid DNA). Just recorded audio live, so no syncing. Windows Movie Maker for editing, not that there was much.

Thanks bg4m3r for the twrp video! I was able to backup my sytsem and then I installed the OTG kernel from Spock. OTG now works great!

Thank you! I rooted my Volt SL740 using LG One Click Root, and installed TWRP using Kernel Adiutor. My question is how was I able to do that without unlocking the bootloader? Or did I?...I sure don't remember doing it.

We use a utility called BUMP to sign the boot partition so it doesn't trigger the bootloader protection.

I see. But I don't remember installing BUMP on my Volt. Is BUMP embedded in the TWRP image?

It's something the Dev does when compiling. Invisible to the user.
