hey guys, im new here but thought this would be the best place to ask.
i am having a problem with my lg g3 since i bought it, at first the phone would randomly turn off when using the camera and i would have remove the back cover and remove the battery for a few seconds just for it to be able to turn back on again, which as you can imagine with a brand new high end phone incredibly frustrating!!
a few months down the line i am having a different problem this time, whenever i have the phone on speaker phone in a call it does it again and instantly turns off. even if i take the battery out it doesn't come back on i have to leave the battery out for about a minute or 2 before it will switch back on. i have returned the phone on the first instance a week after i bought it but now i dont know what to do.. it seems it must be a widespread issue with the phone as i have gone through 3 of the same devices from the store and they all do it.
has anyone else had the same problem on here, and does anyone know the solution to it?
thanks so much for reading hope you have time to help me out as im not very experienced in phone issues.
ps these recaptcha are umm different shall i say.. ive been here for 5mins trying to get one correct am i being stupid?

So, my G3 is completely dead, failing to boot. I know the screen and battery are absolutely fine as I get battery warnings displayed when no battery is inserted or when it's actually dead. I've decided the cheapest option would be for me to replace the main board and have found an exact replacement for my model (16GB, 2GB RAM, D855).
Seen a teardown on YouTube and having taken other devices apart before (once worked for LG themselves) it looks easy enough for me to do. My only question is, will I experience any problems replacing the MoBo or should it be a simple process in regards to getting it to boot?
Sorry if I haven't bee specific enough, I'll try to explain as best as I can if anyone wants to know more.
I just ordered a G3 off ebay and was trying to get some suggestions before it gets here on what to do with it. it will be my daily phone and was wondering what roms would be recommended. Battery life is my number one concern with a phone so hopefully that will help narrow it down
Hi
The other day I was looking for cell ID info on my LG G4 that I have had for a long time in the "hidden menus". I accidentally clicked on the radio test and the screen froze up. I tried to get out of it, but noting would work, not even the power button. After a few minutes, I saw the power off sequence. When I went to turn if back on, it would not power on. I plugged it in, no charge. I tried to boot to recover, nothing. I have the service manual for the h815 variant which differs from mine. I do not have a boardview or anything.
I know trying to permanently fix it is a lost cause, it is old and it had other problems, such as the headphone jack not working even after I replaced it, and the read camera's autofocus being stuck after I replaced it with a cheap knockoff. However, I want to get it running long enough to get important things off of it. I was foolish and a few of my 2FAs are only on that device, and while I have gotten most of them switched to my alternate, I need to make sure to get the rest. I'm not sure which troubleshooting route to follow: Power? Crash/No Boot? No charge? I would follow each but some of the differences between the board I have and the service manual includes a few of the test points I need. Currently I have to attach wires to my multimeter leads to get small enough tips.
If anyone has anything that can help me get this running for a bit, let me know please.\
edit: biggest problem is I don't know how to tell from the schematic what pin is which on the board

Sounds like the ilapo but as you have modified the hardware it can be everything of course . anyways it wouldn't hurt to try some of the Bootloop fixes which you can find in my signature . Your best chance might be flashing the TWRP version for the ilapo and trying to load the recovery. Another option is of course to get into download mode and use salt to backup the user data partition.
Ilapo TWRP (when your device is unlocked only):
