Bootloop on CMWR and phone never close, only without battery!
Today i want to upgrade my android, and surprise! When i push "install"and phone is was restarted, is entered in a continuos loop restart directly in CMWR mode. Here, it was impossible to install anything or make any changes, only "restart", and again, the phone is restarting directly in CMWR mode. At first I thought I bricked my phone, because even in emergency mode it could not start
BUT all this is madeit with battery inside!
After reading what was written here, I realized that I have to remove the battery, and surprise, on the second attempt i managed to start in emergency mode! (with usb cable connected to PC! )
Now, i openet the "LG Mobile Support Tool" (with usb connected to PC), and after LG mobile tool i let to check and install the last version of USB drivers , it was able to communicate with my PC. After that, i installed the latest available version of Android, via LG Mobile Tool and now is working.
BUT i lost the root of the phone. Anyway, it's the phone of my wife, and she's not interested in "walked" through it
Thanks to "andersonlima" , i understand that as long as boots, is not bricked !
Good luck in the future, and most importantly, read well, with calmness, that can occur various ideas, along with what you have in face, may lead to solving your problem!
