Problem with boot loop - AT&T LG G2

Hello.
I got stuk on the firmware update screen after a factory reset that never rebooted (Maybe it's because I'm having a problem with the USB port. Anyway I tried this guide http://forum.xda-developers.com/showthread.php?t=2663369 for flashing stock jelly bean (I was already in there before the softbrick) and everything went perfect, it rebooted to android, powered back of and got a PASS message at the end, but after I unplugged the phone and powered ON I got the Firmware Update screen again.
Tried another time but I decided to stop the process once it reboot to android, the phone it worked fine as long as I keep it on, if I power it off I will get the damn Firmware Update screen again after I power it ON. Also if I try a factory reset it will reboot to that screen.
Thanks in advance.

Kies Firmware Update Screwed up my 6210

I plugged in my device and Kies said there was a firmware update. I let it go through it's paces and upon reboot, it just sits at a pulsating samsung logo.
I've tried reflashing a stock GB image using Odin. Even tried an ICS one. All of them result in the same pulsating samsung logo going nowhere.
What steps can I take from here?
Power + Vol Up
Select Wipe/Factory Reset
Cross your fingers...
Good Luck
I couldn't get recovery to come up before. But it did this time . Anyway, we're back in business. ICS is fantastic on this!
Hi people, I update my tab7+ 6210 to ICS everything was fine, but sometimes I got random reboots and today it suddenly turn off, I tried to turn on but nothing happens, so I plugged into charge but show no signs of life, I tried to enter stock recovery but accidentally enter download mode, Im screwed?, please I need some guidance. Thanks.

Stuck at Boot Logo

Hi guys!
First off, I'm running on KatKiss 217. For a while now I've been stuck to the boot screen of my tablet. Before that I was using it while USB connected to the PC in our office. But then the battery run out so it turned off, I disconnected it and went back home to charge. When I turned it on while charging it was stuck on the boot screen.
Since I was going to upgrade to KatKiss 218, I went on ahead and flashed the 218. So I Format system, installed KatKiss 218 and cleared Dalvik/Cache. When I rebooted it gets past the boot screen but gets stuck on Android Upgrading: Starting Apps. Tried to revert back to KatKiss 217 but same thing happens.
Any idea how I can fix this? Hope you guys could help me out. Thanks in advance!
I think first of you must flash also the gapps. And full wipe would help too it stalled at start-up screen.
Sometimes flashing the same file twice would force it to installed properly and boot it successfully.
Finally got it to work! As you said, I had to do a Factory reset first to get it to work. Not sure why since I never had to do it before. Still, got it to work now. Thanks, man!

[Q] Bootloop after applying GPS antenna fix

I was having terrible GPS reception and I tried the antenna fix- sliding a tiny peace of thick paper under the antenna connectors:
https://www.youtube.com/watch?v=K1-uCIb-t8I
After powering up the phone booted once, then rebooted after couple of seconds and has been bootlooping on Google logo since.
- Takes much more time than normally to power on, then falls into Google logo bootloop,
- Cannot go into bootloader, power + vol buttond doesn't do a thing,
- If I hold vol up + vol down while bootlooping it powers off,
- Plugging in doesn't change anything, no charging indicator when powered off.
Is there anything I can do ?
Did I kill my phone ? If so, how ? What could I have damaged by simply prying the cover open ?
Are all the connections secure?
I checked all the connectors, they're ok.
After a day or so the phone got back to the living- I was able to boot and play around for a while.
Then I tried to update (I got the Lolipop OTA), which failed...
Downloaded the factory image and the flash attempt always gets stuck at " sending 'system'"...
Bootloader, radio, recovery, boot, everything gets flashed, then it gets stuck at flashing "system".
Any ideas ?
EDIT:
Flashed 4.4.4 in NRT without any problems, boots normally, still cannot flash Lolipop ...

Might need to wait for 5.1
5.0 is buggy

Stuck at boot screen even after restore with tot method...

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.

LG G3 stuck in bootloop, even after flashing stock ROM

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.
