[Q] Stuck in bootloop - ATT model - G2 Q&A, Help & Troubleshooting

I installed Scotts most recent Clean Rom and then tried to install burningmembers mods. Afterward going to reboot, it's been stuck in a bootloop. I tried to flash back to stock through the LG flash tool but it says it's the wrong device number - D802. WUnless you know of a manual to access recovery. I'm stumped. Also, I tried to factory reset through TWRP method (vol - and power, selecting yes twice). No go. Please advise if you can.
I've also been trying to use the LGMlauncher tool but it keeps crashing on me.

Have you try the stock recovery? Power and volume down?

I've got a soft brick going on

OK, I've had my S4 a couple months. It's already been rooted, with TWRP installed and also MDOB custom ROM. But tonight I decided to replace TWRP recovery with CWM then I was going to flash CM 10.2. after flashing CWM I now have the yellow triangle and a message saying "system software not authorized by AT&T has been found on your phone" and the phone won't boot nor recovery is working. With no recovery I can't reflash the current ROM i had installed, I have the MDOB file on my memory card ready to reflash, but the phone won't do nothing. What to do now?
Can you get into download mode by pressing home, power, and volume down at the same time while booting up? If so, you could use this guide I've had success with. http://galaxys4root.com/galaxy-s4-tutorials/how-to-unroot-galaxy-s4-and-remove-root-completely/

I had a similar issue were I flashed philz recovery and it wasn't the loki'd zip.I to had the triangle of death with unauthorized ATT msg, I tried three times to boot into recovery and the last time I tried it went to (pic posted)and from there I pushed down for restart phone.it booted up like a regular reboot and was OK.
Also after it booted I lost custom recovery, so like I did the first time I achieved recovery I flashed with ROM manager clicking the T-Mobile S4 when prompted. Note : only use ROM manager to flash recovery.now use recovery to flash a auto Loki recovery. Hit thanks if I helped

Can't boot, Can't get into recovery, Can't flash to stock.

I appear to be bricked. I flashed a recovery via flashify. Phone gets stuck on fastboot. This is coming from Houstonn's excellent PA rom. Tried to go to recovery. Goes back to fastboot. It just shows udc start. Tried connecting to my PC to flash another recovery via fastboot and it's a no go. Just shows wating for fastboot. Booting doesnt work either. Bootloop. So I figured game over and I'll flash to stock. To my horror, the restore process stops at 49%. Apparently, you have to come from a stock based kernal for it to work. Am I bricked for good?
Hello you must flash a stock Rom in the download mode.
Sorry... I don't saw that the flash stops
Then you must install twrp and costumrome again

Thanks for trying to help. I got it fixed without losing data. I got it to boot into the rom after shutting it down for an hour. Apparently it was overheating thats why it didn't boot. But if for stuck at the starting apps screen. So used adb to flash recovery again. Booted into recovery and reflashed rom after clearing data. Running like a champ now.

[q] lg g2 ota update stuck!!!

Heres my situation. I have TWRP Custom Recovery installed on my rooted g2. Tonight my phone decided to automatically take the OTA update for sprint, and i was stock booting to twrp. I powered off the device and tried to boot it back up, but it went straight to twrp. SO i decided to restore a back up i had. Did that, after it was done, rebooted. and it still came back to twrp. IN a panic, i went to wipe, and did a factory reset. Which completely wiped everything, obviously, including my backups. So now im stuck with a phone booting into twrp and not being able to do anything. I just want stock firmware, no root and back to stock recovery. As you can tell, im pretty new to this.
Someone pleaseeee help me!!!
Try to download stock rom and put it in USB. In twrp flash the Rom via USB-otg. Or try this If you want to go back to stock Unrooted.

Ok ill try this, im downloading the files now. If this doesnt work, could i possibly try flashing another rom through twrp??
No, they will all fail. Never ever take otas when rooted. Once you have reverted to stock and rerooted then load custom rom or delete the update files so this never happens again

Nick, did you resolve this? I'm in the same boat, but by a different path.
I wanted to flash a zip, the cwm I had installed failed to flash it, so I decided to use flashify to flash Philz modded CWM, since then, I can only boot to recovery.
On hind-sight, there was an update threatening to install..
I can only boot into recovery, can't seem to get into download mode. Cant sideload, as ADB does not recognize.
Stock rooted D80010d on ATT D800
Fixed

If you need ADB, you may have to change your driver to LGE single sooner adb device (device manager)
There was a third command added later in the thread.

Help! Updated while rooted, stuck in TWRP

So I am fairly new to rooting and didn't know that it's not a great idea to do an OTA update while you're rooted. So I did just that and when prompted to restart the phone, it did and loaded directly in to TWRP. I tried to just reboot from there and it kept going back to TWRP. So I tried to recovery from a backup, same thing, right back to TWRP. Also, I can't get into download mode. What do I do?

You need to first download the kdz and lg flash utility with drivers.
Install drivers
The factory reset deleting system, cache, internal sd.
Then shutdown your g2.
Start to downloaded mode connecting your g2
Flash kdz & voila... Done
I too bricked my phone before. My flashing stuck at 49%. Recovered using above method, all is well now
This works 1000%. I bet on it. Just remember to wipe the phone completely before flashing. You will return to stock with unrooted status in download mode. U will have your warranty back too
