This morning i was using my phone like every day, but i notice that i had no signal so i decided to restart the phone. When it restarted out of nowhere the phone started to boot loop.. i didnt do anything for it to start doing that.. after a long while trying to fix it i gave up and got into recovery and decided to clean install the rom. It did install but after 1 minute of being on the screen it would boot loop.. I download it the same rom and installed it and still kept doing the same thing.. i had a back up so i decided to install it which i did but again after 40 seconds of start up it would boot loop.. finally, i decided to use the LG Flash tool TWICE and it did work but again after a little while the phone turns off and on.. idk what lese to do??? any ideas?
