To preface, I can boot into download mode and access hard reset but cannot boot into the ROM as it just shows the "Broken Android" symbol
I've been trying a lot of steps.... So many guides... To fix my phone. I've chalked it up to an issue with my IMEI/ESF being corrupted as LG Flash Tool shows it as NULL" and fails after 3 seconds consistently. LG UP also fails at 6% spitting out generic errors. I've even tried LGMobile Support Tool and it downloaded the correct firmware but failed to apply it at 2% consistently.
I'm assuming this has to do with my ESF being corrupted. I've been looking up guides on how to "fix" it but keep coming up short as ALL of them require a back up or at least being able to boot into a ROM. However, no ROM will flash. The bootloader is locked and the device has no root options. At this point I'm drawing a blank. I've been going at this for 11 hours straight (no joke, been sitting here for 11 hours searching the forums for different fixes because I know how people feel about the same thing popping up repeatedly.
What caused this issue was trying to roll back the firmware to an earlier version using LGUP so I could unlock the bootloader. I've only been attempting with stock roms (both KDZ and TOT)
Any help would be appreciated.
The phone is still detected in DLMode and all the programs can find it and know it's a D852 but just wont take any firmware.

First of i'd like to thank the community! I've ran in to numerous issues and have been graciously saved several times.
I'll start of by providing some context in to the issue.
original configuration:
Unlocked - T-Mobile US SIM
AT&T LG E980 factory tot 4.1.2 - flashed using LG Flashing Tool
Root - E980 Universal Root
Unlocked Bootloader - Freegee [Android Marketplace]
Installed Recovery TWRP v2.6 - Freegee [Android Marketplace]
Removed bloatware - AT&T Applications
So from this point the phone was working as expected. I spent hours configuring to my liking and decided to call it a night. Before I called it quits I decided to make a backup using TWRP. Backup took a really long time but it said successful. I left handset plugged in to charger overnight, roughly 6 hours of continuous charging. When I woke up I noticed the phone was in recovery mode. Touchscreen was also unresponsive. I held the power button to allow it to reboot and it rebooted me back to recovery. At this point I knew something was wrong. I attempted to re-install backup files made from previous night, this failed. The phone booted back to recovery. I then installing some zip files I had pre-loaded on to the external SD card, this was CM10.1 and gapps files for E980. I tried this out a few days ago and it was working fine. I decided lets try installing this and see what happens. Install was successful and rebooted. The phone boots back in to recovery. At this point I'm really frustrated. I checked the memory card by running through the TWRP menu. I noticed the file sizes were unchanged but the files were not displayed on both in/ext memory. I decided to finally restore again by using LG Flashing Tool. This by the way has saved my a$$ numerous times. So the one thing I would note, at the 85% when the phone reboots I noticed there was an error, an error I've never seen before. It was a picture of sync icon (large) and android man on top of it and text that said "error 0x123456" I didn't note the exact string. I let it go and monitored the flashing tool, somewhere around 93-95% it rebooted again in to the normal boot sequence. Viola my phone is back to where I started.
So here's some of the questions I had:
How did I end up in the TWRP Recovery boot loop?
Why could I not see the files to install once in TWRP?
Why did TWRP continuously boot back in to recovery mode after successful install of restore?
Why did TWRP continuously boot back in to recovery mode after successful install of CM10.1/gapps zip?
Has anyone seen the LG Flashing Tool error I described above and does anyone have an explanation as to what happened?
Here's my theory on what happened...
My phone was on 4.1.2 as mentioned. I noticed a few times that there was a notification stating the phone had a OTA software update available. The first time I tried to update (already rooted and unlocked) the phone failed to update. The error cited that my phone was believed to be rooted. I paid no attention to this and decided to continue using. Later in the day I noticed the notification again, I opted to try again. The phone updated, or at least tried to. It kept booting in to TWRP Recovery. Nothing I could do could restore it, except flashing using the LG Tool. After experiencing this I knew to leave the OTA alone. I don't know if this is possible but somehow I think the OTA was pushed and forced through while I was sleeping allowing the phone to charge. This is the only time I've seen that behavior. Is that even possible???
Where am I now...?
Phone is restored, I opted to upgrade using the OTA before I start tinkering again. Maybe I won't mess with it at all and leave it alone at this point.
So, i scoured the forums, searched for my error code and nothing...
I have a new E980 that I rooted, installed CWM on and left the stock ROM. Earlier today, I get a notification for an OTA update.
I figured I didn't desperately need root, so I unrooted through SuperSU, and said to hell with it, and accepted the update.
Phone reboots into CWM and is now only booting into it over and over.
I looked up how to recover from it, and I've been trying to flash it using LG Flashtool ver 1.5 and everything goes fine until I actually plug the phone in with download mode on and LG FT in the "Ready!" state. LG FT then starts to flash it, goes to 3%, immediately to 100% and then fails after 5 seconds. Error code F0000002. I tried everything over and over again and I get nothing.
I have my COM port set to 41 and LG Flashtool set up properly according to the tutorials.
Any ideas?
I had to use the LG R&D test tool to flash the panama rom then root & install CWM. With freegee and then restore my stock.E980 AT&T backup. Kept getting a "Previous loadfailed" error with LG flash tool.

I'd be really grateful for anyone who can help me. I could even pay a small reward if I can get this phone to work.
Factory restore/hard reset doesn't work. I press power to confirm, and it says "confirmed" or whatever the message is and stops there.

No such option in the current LG Mobile Support Tool.
When I start it, it checks for software and says I'm up to date.
It lists "Software version: _" which doesn't seem right.
LGFlashTool:
Fails for me every time.
New USB cord on back ports, have tried different ports.
It gives a PID, correct model and IMEI.
Checks Milky, DLL, bin CRC. I've re-downloaded the bin anyway.
When the phone is reconnected, it shows on COM41 and flashes.
System, tz, boot, rpm, aboot, sbl3/2/1, modem.
Then it says Factory Reset and Reboot sleep time
It then reboots and seems to fail recognizing the phone afterward. It gives error F0000002 and says "Download FAIL!!" at 95 or 99%.
LG Flash Tool 2014:
From what I gathered, there IS NO KDZ for the e980.
It was recommended to me to flash the Central America e980H KDZ to possibly restore the bootloader/recovery.
This gets to about 95% and then the phone reboots to the LG logo and hangs. After several minutes of waiting, it says "Upgrade stopped due to an error" and prompts me to try again after removing the battery. This just happens over and over again.
Thanks in advance for any help!
I've flashed the g, k and p tots. One won't even allow me to enter factory restore. The other two just hang if I do, or hang at the LG logo if I don't.
I've also tried following the instructions to make a restore microSD and tried another pre-built one, but it doesn't seem to boot/restore from the card.
What options do I have left? Can anyone help? Thanks.

Refer hyelton's guide for getting stock rom on our phone. Use the flash tool provided in the thread and probably you will be good to go.
Sent from my LG-E980
I assume you didn't read the post? Thanks, but that's the first thing I tried, with every compatible .tot and kdz that exists and every LG flashing tool available. I'm not a newb to rooting and unbricking phones. No offense, and I do appreciate that someone finally replied, but if I wanted someone to tell me to RTFM, use the search, or read the stickies I wouldn't have wasted peoples' time with a post and all of the details of what I tried.
I assume at this point that it's pretty well screwed and nothing short of a JTAG will resurrect it, if that even will. I'm leaning toward a hardware fault or something lower level than any firmware/baseband flashing will touch. :/
How did you bricked your phone the first time? Because if you can enter the download mode to use the flash tool, it shouldn't require you to load from the SD card or use jtag to repair the device. Those are the techniques for the device that's completely dead.
Right, but I tried flashing all of the US .tot images as well ask a kdz for central america. I tried flashing using different tools. I have tried literally every possible way that I can find, and it has the same strange problem of hanging at the LG logo and at the "hard reset" factory recovery screen.
It was brought to me as having a "software issue" from a bad update. I wasn't able to determine whether that was factory OTA or flashing a rom, but this thing apparently has some issues that a flash to 100% factory will not resolve. Either it's unable to flash itself through download mode, or it flashes and they all have the same problem afterward. I re-downloaded and re-checked the md5s over and over again. Tried different ports and cables, despite never having had a problem before on this computer with a dozen other devices, several times each.
I'm fairly certain there's a low level firmware or hardware fault so I've ditched the phone. No purpose in continuing the thread unless someone else has the same issue. And in that case, I cannot help without obtaining some kind of adb or fastboot.
Thanks for the replies all the same.
May be the motherboard is the problem?
Try charging

Stock kdz here
If you ever flashed KDZ to your e980, LGFlashTool will not allow you to flash TOT files by means of Download Mode, because there's a check for device model which doesn't match (that info afaik is based on SBL3 content).
If you have Dowload Mode functioning: (1) flash any KDZ (preferably for the same size of memory, 32GB) and you will have a working phone; (2) root the system; (3) replace boot partitions by those from native e980 installation (all together) by means of dd command; (4) flash native TOT file from Download Mode.
Be very cautious while on p.3. If you do this wrong, you will have a hard brick which will require special tools to fix it.
Hello and sorry if this is the wrong category...
It's my first time making a thread on xda.
I've been looking for an answer for the past 2 hours, but I still have a bricked phone... As the title says, I can't enter the recovery mode anymore. I tried to do a factory reset (when I could enter the recovery mode) and the phone got stuck at erasing. Now I can't enter the recovery mode anymore. I downloaded a new firmware from sammobile for the SM-G925F. The firmware works since I used it on an other phone and everything worked just fine. The problem is, when I open Odin and add the .tar file to AP, it gets stuck at nand write and sometimes on boot.img. The phone isn't showing that it's downloading anything (it has no progress bar). At this point I have no idea what to do...
Some extra info that could be helpful:
The phone was bootlooping when I got to fix it;
I work in a kind of phone repair store where customers bring their phones for hardware and software repair. I do the software;
I've installed new firmwares on multiple phones and I never had something like this... Normally some time with google and xda could help me to find a working way to fix the problem, but as I said... I've been looking for 2 hours and the problem is still here;
I'm not a pro with Android and phones. I just like to learn new things and I'm still learning.
Could it be a hardware problem?
Can you show me your phone's download mode image to see where could be the problem?
Also, make sure you are flashing latest firmware, if you are downgrading it - than you will get such boot errors.
*Update*
I found out what was wrong. The eMMC chip was broken.
Hello, first of all I want to apologise if this problem was already discussed, I tried searching in threads and also using the old friend google, but found nothing related.
So, yesterday, I managed to flash the a.o.s.c.p cypher OS (https://forum.xda-developers.com/g4/development/g4-cypheros-t3680102), Oreo version, and after I tried rooting with Magisk I've got bootloop issues with the rom. After this, I reinstalled the zip file and it managed to go back to the OS, but every installed app would crash when tried to open. Because I did not find my backups (not too organised, I know) I tried flashing through LG UP the "LGH815 EU Nougat 7.0 BySezerSimsek.tot" file I had downloaded on my laptop, unfortunatelly, after 10~ seconds, the download mode just restarted and since then (though, it was doing this before I tried to flash with LG Up, but I thought that after I start flashing it will not reboot...), everytime I try to boot my device either normal or to recovery mode, it goes automatically to download mode, where it stays for 10 seconds and then reboots (So I'm not able anymore to use LG UP).
Also, tried LGMobile Support tool, but because I cannot keep the phone in download mode more than 10 seconds, it fails to do anything, it finished to download a firmware for it, but was unable to flash it.
Is there any chance I can "revive" it? the battery was about 50% when I started the first try with download mode, so now, it should be around 20-30% I guess.
In Download Mode, in the box, it says:
633A B49
Modified
P.S.1: After reading some more threads, I found that some people were stuck at 9% while flashing with lg up, but for me, as I said before, the download mode just keeps restarting no matter what I do with it ( even if I just leave it not connected to the pc)
P.S.2: After some more flashing with LGUP tries, I came to conclusion that the download mode restarts after ~17 seconds, and now, in the rectangle it says:
633A B56
Modified
P.S.3: I have been trying to flash "Europe H81520D_00_0115.kdz" and sometimes, if I get the timings right, I can get up to 25% (it restarts at 9%, ~19% and then 24-25%, so, it doesn't always give error after restarting and reconnecting to LG UP). I used the .dll extracted from .kdz file.
Hello, i have the exact same problem as yours with the same custom rom.
My phone stays around 20 seconds in download mode, i can launch LG UP to flash H81520i but 20 seconds is just not enough to flash the LG G4 firmware AFAIK.
I did see that there are some ways to launch the Qualcomm emergency mode but we'll need to disassemble the phone to short two pins to force it to boot in this mode.
I finally found the solution ! Follow this tutorial : https://forum.xda-developers.com/g4/general/guide-proper-h815-unbrick-qfil-files-t3709212 You'll need to disassemble the phone in order to do this tutorial, after you've done the emmc flash you will need to reflash a rom with LGUP.

Thank you for the reply.
I already fix my G4, but unfortunatelly I do not have like a detailed fix because: I went to a "Phone repair shop" and I left my phone there for one day. As I said, before I was not able to boot into recovery, the phone was restarting in download mode after ~17 seconds, and I had no idea about the battery percentage.
The next day I took back the phone and the guy there told me that there was not much he could do, but when I got home, the moment I tried to boot it, it went to recovery mode (twrp) where I tried to install a ROM (I forgot which one, but it was a .zip) and it failed to mount /cache. After that, I tried booting into download mode where it stayed for as long time as I needed without restarting. I was trying to flash 20D version (failed at 25% everytime) until I found this thread where the advice was to use the 20P version. After that it just worked fine.
So, I have no idea what did the guy from the "repair shop", I don't now if it was just related to my battery "running out of juice" or maybe he used any other "magic" box with tools for android smartphones (I've got back my phone with ~60% battery).
Also, before I went to the repair shop, I tried a method I found on xda, unfortunately I could not find the link right now, where I had to format a micro sd card and kind of "flash" (it's not actually flashing) a file to the SD card, put it inside the phone and just boot into Download mode (I'm not sure if it affected somehow the state of my phone)
