[help request] unable to access UI / recovery, no USB debugging, only fastboot - LG V20 Questions & Answers

I have an issue I'm hoping someone can help me with. I'll try to keep it brief.
I rooted my phone, successfully, but in the process the phone app mysteriously disappeared, not sure why. I download the stock apk's from 'theandroidsoul.com/download-lg-v20-stock-apps/, and dropped the phone app into the system app directory, set the permissions, and rebooted. Yes, I know that was probably pretty stupid to try.
Anyway, I can't access the UI as the constant, endless crash caused by com.android.phone. Phone OS is done, so I attempted to get into recovery, re-flash, no big deal.
In previous LG phones, to access recovery via the hardware buttons, you had to go through a menu that made it appear your phone would be factory reset, but wouldn't, and bring you to TWRP after selecting 'yes'. Except with the V20, it actually does reset your phone. USB debugging, disabled now!!
So I can't find out how the hell to access recovery from the hardware, USB debugging is disabled so I can't adb push recovery files, can't access UI, and every fastboot command I run returns 'remote:unknown command', probably due to the USB debugging authorization being revoked.
I know I got myself into this mess, I tinkered too much, and I realize it was an amateur move.
My question is, how can I get out of this? Can't use LG flashtool as I don't have relevant .dll. Can't access recovery (so far; I've tried 50x). Can anyone help? Do I just need to wait for LG to release TOT / KDZ files?

One clarification - when I select the option to factory reset via the hardware button menu - TWRP actually performs the wipe. So its on there. It just resets it and reboots. I can't get into TWRP!

Im having the same problem. "encryption unsuccessful" on white screen. dont know what to do or where to go from here.

All we need is the .dll file for the V20 so we can flash the TOT with the LGUP tool. Until then I think we're out of luck.

Bricked stuck on white encryption error corruption
Messed up. Bricked lg v20 h18. Hopefully someone can help us.

LG L5 E610 - Strange issue

Hello guys.
I have an LG L5 (E610) that is having a very strange behavior.
It started by throwing a lot of ANR with different applications (Google Play Store, Play Services, Facebook, and others).
So, seeing this, I decided to do a factory reset. After reboot, what is my surprise that I see everything as I had before. All the applications, all the data, everything.
With this, I tried almost everything at the moment. And by saying that, I mean:
- Tried to follow the key combination for the recovery, it goes to recovery, I see the Android and some progress bar moving, but after the reboot, the system remains with no change;
- When on the system, I uninstall applications, they seem to be uninstalled, but after a reboot all the applications are back.
- Tried to root the phone with more than one process, no success. I cannot install any application. Not via play store, not via adb install, there is no way;
- Tried to flash a recovery img, to try to clean cache partition from there, no luck. From Fastboot it says everything went well, but when I reboot, everything is the same;
- In fastboot, I tried to erase cache and userdate partitions, no luck. When I try, i have a message saying "FAILED (status read failed (Too many links))". This happens with all the partitions. I even tried to erase the system partition, and I have the same response. Strange thing is that after this error, the phone reboots and goes directly to the system;
- Tried with KDZ images and tools to install different versions, I receive errors during the deployment and at the end the phone reboots. Again, the same system is installed as before. No changes.
As of now, I was trying to understand if there is any problem with the internal flash system. Maybe it is corrupted and is causing all these issues.
The thing is, as the phone is not rooted, I cannot launch a e2fsck to the maybe faulty mmcblk0pXX
The phone has a stock ROM based on Android 4.0.3 (build IML74K / LG-E610-V10e-JUN-30-2012)
I am out of ideas, I've looked around here at XDA, Google and I have no other ideas to try.
Does anyone have another suggestion?
Is there something else I can do to try to make the phone live again?
Any help someone can provide will be very much appreciated..
Now this is what I call a coincidence.
About 2 years ago, a friend of mine asked me for help with her E610. Almost all actions were giving us ANRs. Whatever you do, i.e. unsinstall, install, change, delete... after reboot/reset were all there, even notifications! Tried KDZ updater, and, while the update was OK without signs of errors or so, after reboot - nothing, everything was like before. After trying to find a solutions by hundreds of ways, with adb and fastboot commands (all partitions&folders were locked, no read, no write, and you can't see any file, tried root to no avail), L5 got bricked. She already got a new phone and this LG was laying there without any use.
Three days ago I decided to try again, with no hope tbh No screen, no vibration, nothing, apparently dead. But, I could install Qualcomm drivers and my Windows can see it in download mode. I think that the only way is to flash the phone with LGFlashTool and using COM port. I already extracted *.dz from *.kdz but I need the dll for FlashTool. Found 2 or 3 webs with this dll, but you need a 100 bucks subscription :crying: If anyone can upload that dll I'd be very happy to try to flash this phone I'm really big n00b in this, just a plain phone user, nothing more, so don't blame me if I said something wrong
Many thanks in advance.
same problem
Hello! Same problem...
My L5 is making me crazy... It has CyanogenMod 10 nighlty. A friend of mine was using it and he tried to install the GAPPS after he did a factory reset. I have no idea what guide he used but it got soft bricked... It's constantly showing a "stopped working" message and after a while reboots by itself.
I tried to do a factory reset but it always returns to the same point, same apps installed, everything like the reset never happened. I even used CWM to reset it and it allways goes back to the same recovery point.
After a while I decided to flash a stock room but here's the problem: I can't get into emergency mode.
After reading ALL post about it I found that there's at least three ways of entering EM, (1) down VOL and plug in usb cable without battery; (2) down+up VOL and plug in usb; (3) down+up VOL + power botton.
Conclusions:
(1) - gives me a screen full of code like a command line
(2) - White screen
(3) - White screen
I've read ALL the unbrinking post on the internet, including xda, and none of them helped.
The KDZ Updater never recognizes the phone. I installed all the drivers but everytime I plug in the phone it installes the same LGE MTP drive...
Can anyone help, please?!
How to enter Emergency mode? How to flash another rom?

LG G2 is EXTREMELY Broken. I Need IMMEDIATE HELP.

I recently bought a LG G2 for a great price, when I got it back to my home and turned it on, I discovered something. I found that it wouldn't boot and Download Mode is REALLY BROKEN. I can still get into TWRP, but the UI is in ruins and I can't navigate. When I try to enter Download mode, I get used to get an error code. Something like: error: cannot verify download mode, or something like that and when I try for a normal boot, I just get stuck at pixelated display. Really what to get this phone working, I can't disassemble the phone and I don't have the tools nor money to get said tools. When I power it on, I get an extremely pixelated display and I don't see the LG logo anywhere when I boot it up. I have been able to get the logo to appear once or twice. There is no warranty on this phone, can't afford to send it back to LG. I am getting very stress out over this device.
Things/Methods I have tried:
1) I tried to enter Download Mode, but it 'crashed' per se, and it then proceeds to wreck my PC, by flooding my display with Windows Explorer pop-ups.
2) Tried a normal boot after I restored my previous ROM before this stuff began, and it did no good.
3) Tried to get into fastboot, but apparently, it doesn't seem to exist on it, so I can't use other methods.
4) I downloaded the appropriate KDZ file for my phone to try and flash it back to stock, but the LG Flash Tool didn't recognize my device. I attempted to try and use the Minimal ADB and Fastboot tool, but it didn't to anything for my phone. Everytime I entered a command, it's say "<Waiting for Device>" and then it'd proceed to freeze there not do ANYTHING.
5) Tried a normal boot and that did nothing.
6)Tried using the ADB Sideload feature in TWRP, but that proceeded to crash the UI even more and then the device would freeze.
7) Wiped the Dalvik, System, Data, and Cache and then attempted to restore the OS, but then when I tried to get it into the the OS, it'd just boot loop at the pixelated 'boot screen', if that's what you'd call it.
8) Tried to get into fastboot, through Minimal ADB and Fastboot, but nothing happened.
9) Tired to fix Download Mode, but then the error arrives and then the device proceeds to a completely black screen.
10) Contemplated on physically removing the G2 from this plane of terrestrial existence.
I would appreciate the help. I want to get this phone back to Stock Firmware and then use it as my primary device and sell my Moto G.

First verify model number of the phone viz D802/ D803/ 802T. Download original firmware file and Flash appropriate bootstack, download bootstack from https://github.com/lg-devs/bootstacks here.
After flashing boot stack, connect phone with cable to PC.
Use key combination (depending upot the bootstack you choose) to boot into download mode.
Use LG Flash tool to flash original firmware file.
You are good to go!

Download your recovery for your model, try flashing in TWRP if you can, then flash correct ROM for your device *Link*http://www.gregtwallace.com/lgg2-projects/twrp/?version=2.8.7.3
first thing you should do is to know if phone was refurbished, some phone claim to be d802 and they are not..
you do this by opening phone and checking MOTHERBOARD model or variant.

I don't understand how I can flash the boot stack when I cannot connect my G2 to my PC and it work. When I put it into 'Download Mode' I get an error and it crashes, then a bunch of unformatted drives appear and I can't use a flash tool, because my PC doesn't detect that it is connected to the computer.

I can't get anything into the TWRP recovery, I am able to get into TWRP. Outside of that, I can't do much. I can restore my back up, but both of them were post-crash and I can't do anything. I tried the ADB sideload, but it wouldn't launch the file. I enabled MTP (Media Transfer Protocol?) but I didn't see my device.

Trying to recover photos on soft-bricked phone

Hi all,
This is my first post here, I'll try to include everything but please let me know if I am missing any info. I'm using Windows 10, my phone is using Stock ROM 6.0.1, carrier unlocked from Telus to Rogers but bootloader shows device is Locked.
TLDR: I'm trying to recover the photos from my soft-bricked phone before doing a factory reset. I've tried to manually flash the firmware with fastboot by following the steps in service.xml, but the commands all appear to return OKAY without errors but there's no change in the phone's behaviour.
More Info: I've spent the last 2 days reading up on here and elsewhere online to learn as much as I can. I am honestly not sure what caused it the soft-brick. I was using my phone normally yesterday morning when it froze while browsing Facebook, so I tried to power it down, but I got caught in a bootloop and it wouldn't go past the logo screen. It's part of my morning routine to run updates, and I often (though not yesterday) transfer files to/from the phone through a USB cable, so could it be an internal memory problem? Other possibilities, while I was careful ultimately I did download an apk for Pokemon Go before it was released in my country, and I did also download a battery saving app, so there's risks from both of those but the timing seems wrong...
I can get into bootloader and recovery mode, but not factory mode. Wiping the cache partition did not help. The only way to power the phone down is from bootloader, otherwise the phone goes straight to the logo screen.
I've installed ADB/Fastboot using the 15 Second ADB Installer here, and believe I have all of the correct drivers from the WinDroid install. However I did not enable USB Debugging before this happened, so the only way I can get ADB to see the devices is to go to "Apply update from ADB" in recovery mode, but running "adb devices" brings the phone up as sideload. If I'm in bootloader, "fastboot devices" sees it, "adb devices" comes back empty.
I used the file XT1563_LUX_RETCA-ROGERS_6.0.1_MPD24.107-52_cid14_subsidy-RGRCA_CFC.xml.zip from the File Factory folder, and it looks right according to the software version in the .xml files, but I'm still new to this and I'm not sure if my best guess is educated enough.
In general I'm not too squeamish about voiding the warranty and don't care about losing my apps, it's the photos that I really do not want to lose (shame on me for not backing those up!). I'm wondering if there's a way to get my photos back before unlocking or doing a factory reset, but if there's a reliable recovery software I can use after the fact I may have to bite the bullet.
TIA for any help.
An update. I chose to wipe user data (NOT including personalized content), the phone rebooted but is looking different from before. Which in and of itself is alright, but makes me wonder if I flashed the correct firmware...?
During the setup process, I was given the option to restore data from 3 days ago, which was when the soft-brick occurred. I chose to recover most of my apps, however I can't see any photos. I tried Recuva but it could not see anything, I'll be trying trying the Wondershare Dr. Fone Android Recovery program and hope it finds the photos.

I know it's the wrong forum, but....please take a look

I really need the help of one or more of this forums intelligent minds. As I'm sure you'll see, I've posted this in the QA forum, but have had no hits so far....thus the reason for posting here.
So, about 6mos ago, my Nexus 10 stopped working and I couldn't get it back working...eventually moved onto a new tablet, which now I hate....
Anyway, I figured I'd head back to my N10 because I loved it. However, one of the reasons I left it was because it was stuck in bootloop and I was pretty sure it was bricked.
The bad news, I have followed MANY, if not ALL, of the suggestions on getting it back, I just cannot get it to boot. The good news, fastboot connects with the tablet. So, some specifics:
The tablet WILL boot into fastboot and I can send commands and the tablet is unlocked (also, I believe someone said they had issues because they had an older version of ADB and Fastboot. I'm pretty sure I downloaded the 'most current' version 1.4.3). So, with that, I was able to do the fastboot erase functions, such as cache, userdata, system, etc... and then also load the bootloader (mantafm01) and also send the stock .zip file (image-mantaray-....) and the tablet appears to load everything fine. Thumbs up, right? However, when it reboots it stops at the 'erasing' android bot and will not pass that. I left the tablet in that state for a few minutes all the way up to 3 days...no success.
I also tried the above using Wugfresh only to have the same thing occur. So, basically, I am stuck at 'erasing' and I don't know what to do. I feel confident that the tablet has the ability to be brought back to life, I just cannot figure out how/why all of the attempts lead to the same issue.
What I can also tell you is that while fastboot 'sees' the tablet, the tablet does not appear as a device in "My Computer" like it normally did when connecting via USB. I am using the original USB cable and have tried on multiple computers, all to no avail. I've downloaded/installed the drivers, as instructed on many links. Also, while I can get to the 'Recovery Mode' by pressing Power, Volume Up, Volume Down, if I choose "Recovery Mode" on the tablet, it reboots and goes to the 'erasing' screen. I have tried flashing TWRP on the tablet using fastboot as well. And, sometimes, not all the time, the TWRP blue/black screen appears but it will not progress past that screen (i.e., it doesn't go into recovery).
So, if you can, please help. I believe I have followed all of the instructions, but I have to be missing something or not following something correctly. I'm stoked that it looks like it's only soft-bricked, I just can't get it un-bricked.
Thanks in advance! I'm at my wits' end
Try fastbooting a recovery like TWRP thati s updated then flash a rom.
disclaimer: I might be no help at all!
You have fastboot -- go learn all the fastboot commands... you need to know the tools and figure a solution!
erase... hmm? why? What about factory reset? I see you are not using LOS 13 but stock image... need root? Basically, I would factory reset/wipe sdcard, then install recovery (TWRP) [okay, so first you would need to use fastboot to install custom recovery)...THEN, push (fastboot an image.zip (LOS or stock) to sdcards, install, and reboot!
Good to have WUG... another tool in the chest (I have never seen it or used it)
Ok, so one clue is that if your computer cannot see it, that says to me RED FLAG... ADB drivers? but you say fastboot works, hmm... I think this is the problem... Koush's universal ADB drivers? official Google drivers? Could these help!
Erasing screen? Hmm...
I would say, for the hell of it, try flashing different ROMs, Recoveries, and Drivers.... you are basically trying to...
Factory Reset/wipe SDcard [system, cache, ... everything], Flash custom recovery (optional), then, some how (fastboot or mycomputer) get an image on to /sdcard, then, install, then, reboot!
Good luck!

Why not try this
I have not had this problem with my Nexus 10 but I did once with my Nexus 7 and it may help you.
Instead of trying to flash TWRP and run it (which is not working for you) why not boot into a temporary copy of TWRP and then work from that? To flash TWRP normally (persuming you had renamed the img file to TWRP which makes it easier) you would enter 'fastboot flash recovery twrp.img'. Instead of doing that type 'fastboot boot twrp.img'. This boots into TRWP and from there you will be able run all the options and from there flash TWRP and other images as normal.
If you are having problems with drivers have you used 'USBDeview' ? Run this as Administrator and delete all references to any phone or tablet USB driver and particularly look for devices with Vendor ID '18d1' or '04e8'. Just select them, right click on them and select 'Uninstall Selected Devices'. When they are all cleared reboot your computer and plug your tablet in and it should install the correct driver.
Another option I used successfully with a Nexus 7 in a boot loop was to connect it while running Linux. I don't have a Linux on a computer so I installed one in 'Oracle VM VirtualBox' I don't know Linux but after Googling for help I installed Peppermint Linux and then ADB for Linux. I downloaded the 'TWP' image into a folder in Linux and any other images I wanted. Connect your tablet to the USB port and then on the top menu in VirtualBox select 'Devices' then 'USB' and tick the option which shows your tablet. I then went into what we call a command prompt in Windows but which they call 'Terminal'. Then type 'ADB devices' and if you see it on the list use ADB instead of fastboot. As I mentioned my Nexus 7 was in a boot loop so I typed 'ADB wait-for-device' and as soon as it looped to a point where ADB could see it then the looping stopped and I could flash the images and recover the tablet.
All the best. I hope you are successful.
As long as you can get into bootloader mode, your good.
NOW
If you can't get into boot loader mode? as far as I know...
You're ****ed.
Unless you want to set up usb boot (might not work on Exynos, idk, this is magic to me) and solder the connectors and flash it like they do in factories. That's next level **** too, and considering an N10 is 100$ on amazon you're better off just grabbing a new one.

Stuck in Firmware Update

I was trying to update with LGUP application for firmware update but didn't success, so I removed the USB cable and pressed Volume down and power button to restart. But it went straight into Firmware Update and LGUP application can't find the port.
So, my phone is stucking in Firmware update screen, please help me how to restore the firmware and get out from Firmware Update screen, many thanks and greatly appreciated.
Hold the power button until you get a black screen. Download LG Mobile Support tool and the LG Drivers. Plug USB In and then hold the Power + Volume Up key. On your screen, click Upgrade Recovery. From there, you can do a factory reset through download mode of your phone.
Enter download mode and connect the phone in the PC. Download LG brige and open it. When you are inside the programe you will see a window of Software update enter here and there is an option that is for bad installation otas (to reinstall and correct errors). Use this and I think this will handle.
Another option I think is using LG Up you will see your device in download mode. Try to enter download mode and see if this works also.
Thanks both - I ran into a similar situation. I pulled down both the 11a and 14a KDZ files, and used UpperCut and LGUP to flash first the 14a and then the 11a image. Unfortunately in both cases after LGUP does its thing, I'm getting the LG logo, followed by fastboot screen.
I cannot reboot to get past it, and I cannot flash recovery (it says the boot loader is locked). I cannot flash the Unlock.bin from LG because apparently the KDZ re-enabled the software lock prohibiting bootloader unlocks.
So I'm suck with a phone that will only boot into fastboot, stock recovery or into download mode, and I cannot figure out how to get back to something functional. I've tried reflashing with LGUP - that doesn't work. And the LG Bridge "Update Error Recovery" option gives an error "Connect your mobile device to the USB Port" even though it is, and the LG USB drivers are installed.
Would appreciate any pointers someone could offer.

In older LG phones work LG Flashtool (2014)...Maybe with this you can flash KDZ firmware https://forum.xda-developers.com/showthread.php?t=2797190

I have the same issue - I was on Lineage os and flashing the OTA update caused bootloop to recovery. So I wanted to flash back to stock using LGUP and 14A. I did that before without issues.
This time though all installed fine but after reboot the phone immediately goes to fastboot, exactly as described above. I just spend several hours trying to fix it but with no results. The LG Bridge won't recognize the phone no matter what I do in Windows (tried 3 different PCs). On a Mac it will start connecting and will end up saying "you need to enable MTP connection".
From what I garther the stock rom flashed fine - the factory reset works, even shows "erasing data", the LG UP recognizes the phone as 14A (I tried 11A, 13A too - seems to install fine but goes immediately to fastboot after reboot).
The only thing I realized I did different when flashing the stock rom with LGUP was not using the original LG USB cable. But reflashing with original cable makes not difference now - still going to fastboot.
Any help would be greatly appreciated.
Have you guys been able to do the Upgrade recovery in the LG support tool? Did it work? It starts fine for me but after downloading the recovery file I always get and error, see the screenshot.
I was able to grab the kdz file and tried to flash it with LGUP but still the same thing. It seems like it flashes fine but after reboot it immediately goes to fastboot

Sadly I'm in the same boat as well. I'll pull some of their error messages I've gotten with LG Flash Tool this afternoon. I've tried 2014 and 2017. Both to no success.
I suspect it may be something with the /misc partition. Im going out on a limb, but I'm guessing that the AOSP and Lineage ROMs may touch misc. That partition may have some key identifiers for the LG tools. And the KDZ doesn't have a misc partition embedded inside it.
I was hoping the kdz file I was able to grab from the Lg Support tool would be different from regular stock rom 14a that is available around the internet but it appears to be exactly the same file (based on the file size). My original hope was that the file would support "Refurbish" option in the LGUP tool but it only works with "Upgrade".
I wonder if the "Refurbish" option would fix this and re-flashed all partitions - if only we could find a kdz file that would work with the refurbish option. So far all files I tried (11a, 13a, 14a) only support the upgrade option.
Thanks for all of your helps, I used LGUP and WondersMobile application on the computer and LGUP can not see the port. I did un-install the WondersMobile and LGUP can see the port and finally upgraded to latest firmware.

I too am having same problem. I've tried all the images from 11A to 14A, all of them flash with no errors on LGUP and every time LGUP detects the phone as having the last version flashed. Unfortunately, the phone also boots to fastboot every time. Nothing else to add to your descriptions at this time I'm afraid...

I am absolutely positive my problem is at least in part due to a messed up /misc partition though. @gqo actually described what I did pretty thoroughly in his thread, albeit in a G5. Post #9 has the fix but it didn't work for me.
I've also stumbled upon a menu under the Firmware Update screen that I had never seen before and cannot fin any mention to... Would any of you guys know what it is for? It reads something like:
Code:
** SELECT MENU **
** Select : Power Key(Long) **
** Move : Power Key(Short) **
-> MA-USB(WIFI) DL
POWER OFF
PHONE INFO
BACK
Okay, I figured it out. The menu, at least the first option, appears to be for Wi-Fi firmware update. I wonder what file the phone actually downloads... And if it would be able to fix our phones. The only unprotected network I had in hand was a mobile hotspot in my not-so-LTE Nexus 5, so I got as far the firmware download start but didn't risk it on such a slow and unpredictable network. On top of that my Nexus 5 has also gotten pretty good at bootlooping, that's why I got this G6 in the first place. If anyone out there has a reliable unprotected network and nerves of steel it could be interesting to see if the outcome of this update is different from the LGUP one.
How do you access this menu?
What I started working on yesterday is trying to build a image file for the Qualcomm Flash Image loader and see if I can flash the phone using this tool... But I have never used this tool before, right now it does not detect my phone - I need to work on that + see if I can correctly build the image file from kdz. I found some youtube step by step tutorials so we will see. I will post update on the progress tonight or tomorrow.

I'm not sure if there's a better way to do it, but I access it by removing the usb cable after I successfully get in Download Mode. Then I'm not sure if there's any specific key combo, I've been randomly pressing the power and the volume down buttons and at some point I get into that menu. In the menu though, for some reason, I think I can only select an option if I long press both the volume down and power buttons. The "POWER OFF" option has come in handy because so far is the only way I can actually turn my phone off. The "PHONE INFO" hasn't worked for me yet. The menu also reacts when you add/remove the microsd card... I wonder if it can be used for something other than a WiFi firmware upgrade. I haven't had the chance to connect the phone to a computer to see how the device is recognized, if at all.
And that image you're working on sounds like a neat idea, I wish I could help but I'm afraid I wouldn't have the skill. I may be able to test though. Anyway, Godspeed!

I'll play around a bit and see if I can land on this menu. At this point I'll try anything. I'm on an iPhone until I get this fixed - so I'm motivated!
I can setup an open guest network off my main wi-fi this evening and see what I can find out.
EDIT Sorry, I tried playing around here, but I couldn't figure out how to get back into the the menu you uncovered. If you could give some instructions on how to do it, I'm happy to give it a shot on my device.
I was able to access the menu today...what worked for me was at the firmware screen unplug the usb cable and then press volume down and power button three times quickly. I tried to connect to a wifi and it does not really do anything. I think it just establishes wifi connection but it does not download anything on it's own - it's waiting for another connection.
Also I got stuck with building the image file from kdz, it has no information on partitions. At this point I decided to ship to LG for a quote and will see how much they will ask for a reflash.
I got as far as selecting a network and getting some sort of a download start screen, but I interrupted it right away so I wasn't sure the download would actually go through... Apparently it does not. If this menu has some sort of flashing capabilities though, it might be worth checking how secure it is. If someone can get it to download and flash a modded file perhaps there could be a chance of flashing a custom recovery or something... I'm thinking about those guys that have an unlockable bootloader (which we ironically also have now).
Anyway, all of this goes well beyond my skill so I followed your example and submitted a repair service request to LG. It'll take quite long but shipping is free, so I figured I'd give it a try. I'm assuming this is an easy fix with the right software tools, so I hope LG doesn't overcharge for it. I'm even half hoping they'll do it under the limited warranty... If I recall correctly unlocking the bootloader doesn't immediately void all warranty, there's room to prove the bootloader was never actually unlocked. And after all LG does say that once unlocked, it cannot be undone and our phones are, in fact, running stock firmware and have a locked bootloader.
Update: My phone was received today by LG. In LG's Track Repair page, the status briefly showed as Undergoing Diagnostic but quickly moved to Repair In Progress, it's current status. Given that LG was supposed to contact me in case the repair was not covered by the limited warranty, meaning that an extra fee would've to be paid, I'm assuming the phone will be fixed (if possible, that is) free of charge. I will update you guys again soon, but if anyone out there is still struggling with this issue I'd recommend considering sending the phone to LG.
I have the exact same problem. Please keep us in the loop of what happens to your phone with LG
My phone has been received by LG for this issue on 9/26. It quickly moved through diagnostic to "repair in progress" on the first day plus showed ETA back to me in 6 business days. Ever since that it's stuck in that mode, no update or contact from LG. I check the status every day - every day it says the same - ETA 6 business days. It's been a week and half now with no update. I kind of expected it's going to take 2-3 weeks but annoyed that they say 6 days ETA and then you don't hear from anyone for almost 2 weeks with no change in status.
Update #2: The status finally moved to Shipped To Customer. I haven't been contacted by LG yet, so I guess the phone could've been shipped fixed as much as it could've been shipped as is for being unfixable. Either way, I wasn't and most likely won't be charged. FedEx hasn't got an ETA for the delivery, but I'll let you guys know as soon as I get my phone back.
Edit: Got an e-mail from LG. It reads something like:
Defect: Software failure
Payment Type: NOT APPLICABLE
Repair Results: S/W upgrade (download)
Repair Cost: $ 0.00
Warranty Status: In Warranty
Tax: $ 0.00
Total: $ 0.00
I guess I got away with it, I hope you guys do too.
