I rooted my TB the other day and everything went well. I've been using it with no problems until now. I wake up this morning and it's stuck on the bootloader or fastboot screen and no option that I choose allows my phone to boot up normally. Any help with this matter would be greatly appreciated. Thanks.
Similar Issue
I've had the same thing happen with mine, except after multiple boot loader reboots I can eventually get the phone to boot. Eventually it will display the message "Shutting Down" The longest it's worked before rebooting is 30 minutes, but I've not allowed the VZ update to go through. Any suggestions? Thinking of trying to flash a rom.
Hello Everyone,
I have been trying to help my friend with his soft-bricked G3. He wasn't rooted and had never even played with flashing anything, it just stopped booting one day and would display the "LG Life's Good" boot screen for a few seconds before going black and then just repeating this endlessly. I was able to get into recovery and download mode so I used the tot method to flash back to stock after a hard reset just produced the same results.
When I flashed the stock firmware, everything appeared to work fine, it went through the MiniOS bootup and everything, said success, gave me the hard reset status screen so when it finished I pulled the battery as instructed and rebooted but the phone still has the same issue. I have tried to run factory reset through recovery now that I flashed the new firmware and it still does the same thing, just hangs at the boot screen for a few seconds before going black and then trying again, endlessly.
Has anyone encountered this before? Is it bricked?
Thanks.

Pretty common prob plug it in to the wall charge see if it boots sometimes it still wont but most of the time it will the battery quality on the g3 is crap they last at most a year with a few exceptions i would first order a battery.
Device is a LG G3 D850, rooted, TWRP installed, stock ROM on 5.0.1
Here's the story: Yesterday I was browsing normally when the device froze up, then shut off. Wouldn't power on with the power button. I had to pull the battery and then it turned on. When the device booted back up, it was running very sluggish. Immediately noticed that the WiFi was constantly trying to turn on with no success (When entering the WiFi menu it only said "WiFi turning on"). Bluetooth would not turn on either. The battery was draining rapidly, about 20% in 30 minutes with no use. GSam Battery Monitor reported that Kernel (OS) had used 95% of the battery. I tried rebooting the phone with no success. Booted into recovery and cleared cache, no success. Couldn't find anything online besides people saying to try a different ROM/Stock rom or that they were told it was a failed motherboard. I tolerated using the phone into the night, but the battery was constantly draining and the phone temperature reported ~98 degrees even without use. The WiFi and Bluetooth never started working. Today, a few hours into the day, the phone shut off again. This time it started boot looping, going from the LG splash screen then the spinning AT&T screen, it would then hang and reboot (constantly boot looping). Battery pulls didnt help. Once or twice, the phone actually booted into the OS. After a minute it would start bootlooping again. I then booted into recovery and performed a factory reset. After the factory reset, the phone still bootlooped. I then booted into recovery and recovered to a previous nandroid backup. The phone booted up afterwards, with the WiFi actually working. After 5 minutes, the WiFi stopped working again and the phone proceeded to start bootlooping. My next attempt was to flash back to Stock ROM, using this method: http://forum.xda-developers.com/att-lg-g3/general/unroot-return-to-factory-stock-att-lg-g3-t2820827. The flash worked successfully, booting into the OS on the setup screen, but instantly started bootlooping again... The bootloop is a little different now, going from LG splash screen > Green android with blue spinning circle in his stomach > AT&T splash screen > then rebooting. I cant even get into TWRP now (When trying to boot into recovery and clicking yes on the default factory reset screen, it just reboots instead of going into TWRP) Im out of options, should I give up and buy a new device, or does somebody have any other suggestions?

Sadly that is because of a hardware issue. Been happening. A lot lately.

Alright, that's what I had read. Just seemed like a software issue so I was hoping for the best. I went ahead and ordered a new device. Im guessing a full motherboard replacement would be required to fix the device?
Recurring Issue
Hello,
The same problem happened to me a few days ago so this is trully a recurring issue.
I also tried to fix my rom by reinstalling it, then tried to install multiple new rom, and finally flashed the original stock rom. I also am stuck on the bootloop issue.
I'm going to contact LG to see if they can do anything to repaire it but my hope are very low.
I'll try to update this message if I find a solution.
Mine just started bootlooping and no wifi and today it just died. Battery pulls didnt work either no power at all. Probably going to switch to the V30 when its released.

It's probably to late but theres another method returning to stock KitKat dont know the link off hand in development forums. Sucks you couldnt try no adb methods. Still have the Phone want to sell it i need a cheap screen ?
Last night I tried to flash TWRP just because I wanted to go to a custom ROM- alas, the phone now will not go past the google logo. It usually hangs there for 10-ish seconds and then reboots. Occasionally hangs there indefinitely. It's not a power button issue- the button worked just fine before flashing and I've confirmed it still works normally with a multimeter.
I tried to reflash stock using the Google images and "flashall.bat", which says it succeeded- but the phone still loops. I can get into fastboot, but I get the bootloop even in recovery. Running the similar script through Nexus Root Toolkit always fails on flashing the system partition- usually a buffer error due to a sparse header. Can't even seem to get it to do the "fastboot boot TWRP.img" or whatnot. I've flashed KitKat, Lollipop, and MM stock roms to no avail- they all say they succeed, then continue to bootloop.
I've tried just about everything I've seen on here- but not being able to get into recovery hampers efforts like repairing the persist partition.
Help?
When you boot into recovery, the phone reboots itself? If it does, it could be a sign of a failing power button.
When flashing a stock ROM, are you flashing userdata.img and then performing a factory reset/wipe before booting the phone with a stock ROM for the first time?
When I can get into recovery (without a restart), the phone is totally fine.
I think part of the issue is that the battery ran down while I was trying to do the repair- hence it trying to restart and failing. Power button still seems fine (again, confirmed with a multimeter). I left it plugged in to my iPad charger (since that's a 2A charger) overnight and it was still blinking red in the morning. I moved it upstairs and now I can't even make it that far.
Perhaps the battery was just shot by the time I got the "repair" done, hence the boot loops. Is there any way to revive it shy of cutting open the battery + charging manually (with a bench supply) or just replacing the battery altogether? I may try doing a motherboard swap with my working Nexus 5 just to see if it is in fact the battery.
When the phone is powered off and connected to a power source, do you ever see a flashing red LED? You flashed the correct twrp for the hammerhead?
I would try a new battery because it seems like everything is working.
My father-in-law's S6 was rebooting right after the menu screen came up. After trying numerous things which wouldn't work (still had varying boot loops) like getting into the recovery mode and doing a factory wipe, I decided to use Odin and flash the base stock Android nougat on this (it had the one verizon security patch after that, so should be no issue doing this).
That went okay and it rebooted and got all the way to "Android is starting" which you see after a firmware upgrade. But I didn't realize the battery had run down through all this so it died at this stage. So it was taking a charge now, so let it charge overnight and give it another run.
Got up today, tried to start it...back to the boot loop. So I figured I'd flash stock again with Odin (can always get back to that mode).
It completes successfully and then after the reboot at about 32% jumps to "erasing" and then the boot loop again.
Got into recovery mode once and wiped cache (pointless at this point, but whatever) and did factory reset there, then boot to bootloader. Got all the way to the verizon screen...and then boot loop again.
Is this phone just done? The only thing I can consistently get to is Odin mode. I tried the stock reflash a couple more times and keep ending up in a boot loop and it doesn't even get past the "custom" screen now. And I can't even actually get it to shutdown for that matter. I can get to the battery pull mode but if I try to power off from there, I just get the black screen with the blue light.
And, to make matters even worse, now on restart, it brings up the blue system update screen for a second, then jumps over to the no command screen, sits there for a second, then reboots again. I think I've somehow managed to even blow the recovery menu but this has all been stock and never had any custom firmware or root.
Any help/suggestions would be greatly appreciated!
