I have the LG GPad 7 v410 - it is being returned to me today from LG for in warranty service. It was stuck in a bootloop from the OTA update. I fixed it, but sent it in anyway. They are sending me back my tablet flashed back to 100% stock. my questions:
1) before doing anything else, how do I back up the stock recovery, and stock firmware?
2) where is the latest version of TWRP?
3) is it possible to root the stock lollipop update, without being affected by the bootloop I previously experienced? I would like to use the stock rom until cyanogenmod Rom is on a stable build.
4) is there a root method that does not require a pc?
Thank you in advance for your assistance.
