Need help on bricked and boot-loop LG V50 Thinq KT.. - LG V50 ThinQ Questions & Answers

Hello guys, I bought a used LG V50 Thinq KT 5 months ago and made it as my daily driver. I shot videos for some projects on the phone and I think the problem was because I had a ton of 4K videos on that phone and forgot to delete some of it and the storage probably got full and couldn't handle the background tasks that were mainly running the phone. It began overheating, then frequent freezing of the phone, couldn't even get past the lockscreen because it would just freeze everytime I opened it up. It then just boot-looped everytime I tried to turn on the phone. I actually did the factory reset where you press the power button and volume down button, It went to this factory reset mode and decided to wipe everything. Unfortunately after a couple of seconds it said "Erasing" then it would just boot loop all over again. I researched some tutorials on youtube on how to unbrick phones and want to try to flash a new stock LG V50 ROM. I've downloaded everything and the correct version of the ROM because I can still access the IMEI on my phone. What my problem is now, is that I can't access the bootloader because I haven't turned on the OEM bootloader option on the developer options. I am completely stuck and want to find a way how to turn on the bootloader on this phone without accessing the developer options so that I am able to flash the new stock ROM via LGUP..

any solutions yet ?

Get into download mode by holding vol + and plugging in usb

[Q] LG Optimus Thrive/P506 boot animation loop

My sister has a LG Optimus Thrive(P506) that was working great until yesterday. The phone refused to boot up and every time I plug it into my computer to charge it, it keeps showing the LG logo for 3-4 seconds then powering of for 1 sec then starting again. The phone isn't rooted or anything and it's currently locked to AT&T. Any suggestions what to do? It doesn't boot at all unless it's in a power source. Also, we aren't in the US so the phone has been on airplane mode for 5 months now. Another thing is that ADB doesn't seem to see the device even when connected. Please help!
I remember this happening to my phone when it was fairly new and unviolated... just damn forgot what I did to fix it. I knew I did a factory reset using some button-power combination. It's in the manual. I lost mine.
You could also try booting it without the sim card and sdcard inserted.

The factory reset is activated by pressing power+down volume+home. That triggers the factory reset if u are on stock with no custom recovery.

[Q] Stuck! Phone does't turn on and does not charge

Hello guys I have been struggling for the past week, my LG G2 phone has been rooted, I flash a custom recovery TWRP then I lunched to my stock rom I then tried to update my firmware to 4.4.2 kitkat the update was downloaded successfully, then it told me to reboot, so I did phone switched off then I was stuck on a boot loop but this time it was a boot loop with a error message on the left top corner. and then it would take be to a dim back screen. I searched the entire week to find a method to get me through the start screen and I found this -> NO Recovery mode, No download mode, after OTA on rooted LG G2 http://forum.xda-developers.com/showthread.php?t=2582142 I done exactly what it was showing, then my phone switched off and now it won't power up. Then I tried turning it on NOTHING phone does't show the LED charging lights, does't respond to the usb being plugged in can't do ANYTHING I am guessing the battery has died so now I don't know what to do, either contact LG or should I try getting a battery that is fully charged or even use a factory cable any ideas guys ?
Call LG support.

LG Logo Bootloop - Can't access TWRP - No DL Mode

Hi guys,
New to flashing custom ROMS. Good news - flashed CM12, then LiquidSmooth and I'm learning a lot after having soft bricked my phone a few times. Bad news - After trying to get back to Stock I'm not able to get out of this LG Logo bootloop. The LG logo will flash, screen will go black and the whole process starts again. It doesn’t progress past that. I'm unable to get to TWRP recovery or download mode.
My idiotic move:
Iffy stability with camera and mobile data with CM and LiquidSmooth. Decided to go back to Stock.
I flashed my nandroid backup, which I believe led to a bootloop (can’t remember). Was able to boot to TWRP and get back to CM12. Then I had the genius idea of using AutoREC and selecting the “Go Back to Stock” option. Yes, it’s already sounding like a bad, and nonsensical idea as I say it now. Can't remember exactly what I did next - I either flashed my nandroid backup or did a factory reset through CM settings. Threw me into this bootloop.
The details:
Model - D800 - Am sure of this.
Stock software before flashing CM12 was Lollipop 5.0.2 via OTA.
TWRP Recovery 2.8x something or other. Used AutoRec to flash.
I can interrupt the bootloop and access Factory Hard Reset through Power + Volume Down
Had to go to JB Bootloader in order to Flash ROMs. Errors returned otherwise.
Roadblocks:
No download mode. Holding Volume Up & Inserting USB cable doesn't work. Although am able to get bootloop to include a blank screen with red flashing LED through this method from time to time.
Phone boots up, and goes directly into bootloop when plugging USB cable into phone. This happens both when plugging into a wall charger or into a computer. I think this is probably the biggest pain and is holding up things from progressing. Can turn off phone by holding down power for a few seconds, BUT if the phone is plugged in it will continue to boot on its own.
Phone not recognized by computer & ADB However, was at times able to get Device Manager to recognize the phone as an "Unknown Device" after going to the Factory Hard Reset screen. This is no longer working after trying different drivers. I’ve went through LG Mobile Universal Driver as well as the Koush driver.
Going through Factory Hard Reset via hardware buttons only throws phone back into BootLoop
Can’t boot into TWRP
Any insight or help guys? Thanks in advance. I think getting into Download Mode will be a quiet victory. I’d like to try to use Supersports guide once I get there to go back to stock.

Bootloop on G4 (Can't turn on)

Hey everybody,
I just have a serious problem with my LG G4 H814. Yesterday I was just sitting there, using some Apps and suddenly the application ges frozen and after that the phone just more or less turned off. (So the screen gets black). I tired to replace battery and all this stuff but doesn't work.
Next thing to do for me was to boot into TWRP try to fix problem with wiping dalvik cache and/or restore by nandroid backup...
Problem beeing: I cant boot in Recovery Mode either! Just doesn't work... So I tried to boot in the Stock Recovery of LG to do a factory Reset, wasn't able to do that either!
So last try... reboot into Fastboot Mode (Download Mode) and try rebooting into recovery via adb comands...!
Problem beeing: can't get into Fastboot Mode!
I tried to connect Phone via Bootloader but deosn't work.
So now I'am at a point where I can't turn on my Phone! I mean it wont start up...The screen stays black, no Logo is showing up, no LED NOTHING!
The battery icon doesn't show up when I try to charge my phone...
So tell me: WHAT THE FVCK IS HAPPENING HERE? Do you have any idea on what to do except for bringing it to carrier?
I just want to get to my Data on phone...rest doesn't matter. I could set up everything again?
Device information:
LG G4 H814
TWRP
Xpsosed Framework running (v75 i think)
Modules were working just fine (before everything happened I did an reboot so that the modules are active!

You might want to post in the G4 general or where the H814 model is specific (is that T-Mobile?) This forum is specific to the H810 ATT version.
Additionally, you can see the posts about TOT method for restoring your phone, however this will completely wipe your data.

I think H811 is T-Mobile.
Lg G4 H815 T mobile
Same here with my H815 from T mobile. After a forced update of a start up T mobile screen it stops working and gets in a boot loop. all key combinations don't work so can't start in safemode
my g4 h810 does not turn on. no download mode, no recovery, black screen but can be detected by PC when connected via USB. recognized qualcomm 9008 thing. drivers were successfully installed. Mobile feels lifeless except when connected to PC.
any ideas what's going on, does it mean that my phone is hard-bricked? how to resurrect it?

[Completed] Verizon LGG3 VS985 not booting

Hello
I am new to working on these phones so I apologize in advance if I don't properly state any processes or terms correctly.
I have a stock non modded Verizon LGG3 VS985 that experienced problems with WiFi and Bluetooth not working and significant battery drain. This happened right after a recent update to marshmallow. I tried cache clearing, safe mode, hard reset and nothing solved the problem. I decided I wanted to take the phone back to factory condition. I started with the LG flash tool that uses the .tot and a .dll. I ran the flash and when the program got to approx. 80%(at checking mini os phase of the flash) the phone began to reboot and only got as far as the LG logo and after about 2 min of the phone trying to reboot the flash program said fail, usb connect or something like that. At this point the phone will only start and go into a loop that includes the vibrate and the LG logo. and that will cycle until I believe the battery would die if allowed. I then found a link here at XDA (https://forum.xda-developers.com/verizon-lg-g3/general/guide-flash-to-stock-10b-kdz-method-t2928140) that uses the KDZ method, was well written and easy to follow. I ran it on the phone and it was going great. The flash program got to 88% and the phone went into the boot loop with the vib and LG logo . The flash program continued to run until it was complete while the phone was in the boot loop and it got to 100% and said that the software installed. I powered down the phone via battery removal and now when it tries to boot it vibes, shows the lg log and then the green android symbol shows for about 2 seconds and then it does it all over again. I have tried a hard reset and nothing changes. I appreciate any ideas any of you may have on what I can try to get this resolved. Thank you.
