Hi guys,

I was wondering what could be wrong with my phone:

Basically, I noticed that my battery life starting to decrease. I went ahead and invested in Anker batteries (comes with two of them) so I could basically improve my battery life.
I also had installed an app called Smart Wifi (an app that would detect the wifi's in my home and switch to the strongest/turn off when none detected) in that time period.

Now the current issues I have about a week later:
1. My wifi won't turn on. It's stuck on "turning on" but never does. I think Bluetooth is doing something similar
2. I will have a fully charged battery inside and the phone will eventually go black. I think it's still on because the phone stays warm. I can't seem to revive it. To fix it, I have to remove the battery and re-insert it.

I tried doing a factory reset and that fixed some of the slowing down problems. The black screen and wifi problem is still there. I'm not too good at this stuff, so any insight would be appreciated. I was considering rooting my phone and seeing if I could solve anything after installing a custom ROM but I wanted another pair of opinions first.

Thanks!

For all of the posters on this thread. I may have a solution. I have a zip toolkit that has everything you need to do a complete restore of your d850. It will replace every bit of code that sometimes flashing a new rom doesnt. Now it will have to wait because there is one bug in the instructions that I accidently left out when i helped another guy, so iv contacted him so he could tell me what it was that I missed. But the process ill post here very soon should fix your problems.

Here is the link for the file to download. This zip has everything you need to restore your g3 d850 to complete stock (better than factory reset). And has what you need for root.

********READ QUICK INFO BELOW******
Theres a bit of instruction missing from the included guide so here it is to save yall a confusing headache.

" You have to check mark the "board" box, not SW update...we are downgrading, not upgrading. If you check mark the SW upgrade box, you will end up in a factory reset 2 screen. If that happens just reflash again."

So my problem happened downgrading from marshmallow to kk using lgup. After i used flashtool i didnt get a mini os screen like i always have before it just bootloops but if i keep the battery out long enough it does boot and shows att logo then restarts and bootloops again. The only thing that works is using lollipop kdz from d850pr but i dont get wifi bluetooth or hotspot and the battery drains fast. I wish there was a tot for lollipop i know that would fix it. I did root the d850pr and tried flashing a rooted 20f stock rom but i get boot srcurity and i have to flash all over again. I really dont know why its bootlooping

Well that sucks, it had worked for someone els so it maybe a fluke. An unfortunate one... So one thing to try now is this---

1. Download LG PC Suite here. Don’t worry about USB drivers, this program will automatically install them.

2. Turn your LG G3 off.

3. Connect your LG G3 to your computer and hold the Volume Up button.
4. This will put your phone into Download Mode.

5. After a few seconds in Download mode,
Open LG PC Suite.

6. Tap on the Repair button and follow the steps that the program provides.

7. Wait for the program to fix your LG G3.

Hope this works. If not, ill keep looking for a fix. Im sorry your having these problems. It worked for me and another guy so idk why your bootlooping but I have heard that it can happen even when everything is done right. So lets see what happen. Let me know how the bootloop fix i provided works out.

You have a completely new system so... Theres a chance its a hardware problem. It shouldnt since they are built into the SOC but your phone may have broken antennas. Ill keep looking to see what i can find. One thing to try is flash the nwest radio.
