it was a LG G3 I was trying to help someone with
No matter what the file just wouldn't flash
I'm running CM 12.1 on my G2 and it was rather easy. Just installed towelroot and TWRP apks, supersu from the Play store, rebooted into recovery then wipe and flash.
Hmm, first I bricked my iPhone 5 a year ago, and now I might have bricked my LG G3.
Shall be looking for a cheap phone soon.
Maybe the Samsung A3 is worth it in the short term?
Never get Samsung phones, specially low budget ones.
Can't you take your phone to LG to get it fixed?
