Sprint LG G2 Boot looping topic

hello,

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?

Phone is looping after update topic

A couple weeks ago when my phone was running jb I used Odin, the cf auto run file to root my phone and had no problems at all. After the kik Kat update came out I used Odin on my computer and flashed the original firmware so that I could get the update, I knew I would lose root but now when I try to root it my phone goes into a loop. The only thing I could do to fix it was flash a twrp img. file which got it working again. Can anyone tell me what I'm doing wrong this time around and why it's going into a loop? I would also like to know why you can't write to the external sd card anymore???

[Q] Triangle Screw&Wrench screen Boot Looping topic

A friend has tasked me with restoring her phone which has been stuck on the triangle screen with a screwdriver and wrench. At first i thought it was download mode for sony but after some research from what i can pick up its formatting internal memory or something along those lines. others have solved this problem by waiting it out anywhere from 1-2 minutes to 2-3 hours. I have been running this screen plugged in for probably over six hours now and ive noticed that the progress bar at the bottom does stop and it will reboot but boots directly back into the triangle screen. it does not register on my laptop and i havent been able to boot into fastboot or download mode. Not visible through adb either.

Im pretty sure i have the correct drivers installed but if someone wanted to post a link to drivers they use and are confirmed to work please do so.

Any ideas or help would be greatly appreciated. thanks!
