I can get into download mode, but have a secure boot error and cant use ADB or fastboot. I've been reading every thread I can find.
I tried the LG tool, it never downloads the firmware, just hangs at 12%. Tried different drivers etc. Let it run overnight just in case it was a slow download - nada.
Tried the LG tool by entering the imei number first, but the tool reports a low battery and won't load the firmware. Phone is fully charged, i assume that battery level reporting is not working correctly.
Tried to load the kdz with the R&D tool, it errors out at 49%.
Tried to do the offline process with shttp from the unbrick any phone thread. It uses an older version of the LG tool and won't recognize that the phone is plugged in. If i install the newer tool that sees the phone, the process crashes the tool.
it all started when i tried to flash twrp and used the one for a different model g2. Dumb, I know. this is my first time soft-bricking a device.
Can anyone please point me in another direction?
UPDATE: phone was reporting that it was an 802. Downloaded and flashed an 802 kdz file and the phone booted! First time it was able to get past 49%. Nothing really works on the phone, but now i'm able to use the LG Mobile support tool to flash the correct firmware. The program is downloading the sofware now.
When you say LG tool I'm assuming you're talking about the official program you can download from their site?
I have the Verizon G2 and promptly erased everything on it the first night I got it.. Don't flash / wipe files at 4 AM when you've been up all day and night.
Anyway this thread http://forum.xda-developers.com/showthread.php?t=2432476 really saved my rear. Maybe the T-Mobile version will work to get yours back to stock.

works at the start and hangs at 49%. There is one bit that needs to be switched and this would work.
okay, looks like the phone is reporting that it is a d802 from my first f'd up flash. I think this may be causing the problems with flashing the 801 kdz.
Can i flash an 802 kdz onto an 801? then possibly later go back to 801?

before I flashed with the same tool g2 my lg ls980 and had no problem. But now I can not, reach 6% and reads: Download fail
Attached my photos
I would simply flash it with the full ZVE tot file and the LGFlashTool and that should resolve any issues. Trying to troubleshoot all the little possible things that could be wrong will waste hours if not days and be frustrating as hell - a clean flash takes like 6 mins, tops.

I tried to flash the ZVE version but it shows me the same message with ZVA and ZVC versions:
before had installed AUTOREC for version vs980, but mine was ls980, so I've been trying to repair the phone.
Hello guys, I have a D802 phone and I was on Ressurection Remix 5.0 but since the official lollipop update was made avalaible, I wanted to return to stock and unroot so I could again use my warranty(for some weird reason they couldn't tell last time I took it there that it was rooted). Basically my problem is that every guide for going back to stock has the phone connected to the PC and use the flash tool. Well, I did that but when the mobile support tool opened for the upgrade, it couldn't find my phone. So I found a guide that showed you how to extract and rebuild a kdz file into a .zip. I tried that, used the UK d8023b rom ( A friend of mine who has a d802 as well, though unrooted, got the prompt to update through the pc suite and it updated his phone to d8023b, thats why i used that version), flashed it and I am now stuck in a bootloop. I have full access of recovery and adb but the phone isn't recognised by LG software. Can you please help me use my phone again? Going into download mode didn't work with the flash tool.
Hi mates!
So, here my problem.
I kept my LG G2 as a test phone (I changed recently for the OnePlus Two, one advise, don't buy it, stay with LG, so good phones.), and I manage to unbrick it with this method (I forced the QDLoader Mode as my phone was totally bricked). I flashed back stock with .tot then .kdz file, problem: the phone shows 16GB instead of 32GB. No problem, I fixed it with this method. But now, every time I tried to flash CyanogenMod or others CM-based ROMs (I flash the correct Bootstack, etc), either the phone is stuck on CM bootanimation or go into Qhsusb_Bulk (Many partitions when you plug the phone to a computer).
But for stock / stock-based ROMs (like Cloudy, Stock Flashable Zip 30F from @somboons), no problem, the phone boot into system. What, for you, can cause these problem?
Thanks.
By the way, LG G2 32GB Sock Lollipop D80230F.
a few feeks ago bought a second hand lg g2 d802 running kitkat 4.4.2 wich was only detecting 2g when i try to connect to the internet, i tried to solve this problem by entering the hidden menu and selecting the network types it could detect but no luck, so i decided to upgrade to lollipop, i downloaded the lg support tool and went for it, when the update was done i found myself with an almost completly functioning device except it had the "imei=null" problem, meaning no network at all --"
i tried the QPST but it was unable to detect my phone, so i decided to root my phone and go for a custom rom, the cyanogenmod13 nightly (i don't really know what i was thinking at that point :s ) and when done i was stuck in a bootloop, so i tried flashing a stock rom kdz method but the lg flash tool would stop automatically. since then i've been trying to flash stock TOT roms, the process would stop at 94% and the phone reboots. the screen shows random pixels and lines, the start up lg tune is there and i feel vibration when i press the home buttons location, i've tried to reset it to factory settings and i've used theLGUP_8974.dll, selecting the BOARD DL option in the lg flash tool but that didn't solve the problem. i have read somwhere that it could be a kernal problem, i don't know if i should go that way ( am at that point where i don't want to mess up my device anymore xD ) what do you guys think?
thank you for your help

Sounds like to me you may not have a D802. You'll need to take the back cover off, and look and see what model #s you see. As if your having screen issues that sounds like your flashing a D802 firmware on a D800 or D801.
Also remember flashing will almost always stop before 99%.. Anything after 85% its done this is normal and will almost always happen.
These D802's have a LONG history (mostly bought referbs) of not being what they are being sold as.

the problem has been solved, it tuned out to be an ls980, now my G2 is fully back to life :laugh: thanx alot hyelton for your help :good:
Hello XDA. I recently revived my G6 after it sat in my drawer for years and was delighted to see HavocOS on Oreo still running on it. I popped in my T-Mobile SIM and voila, service. My only issue was horrible data speeds. I tried every network settings and apn fix that is relevant to my device but I was still stuck with virtually no 4G data. So, my last resort was to flash back to stock. Now, I dont know if there is a specific method for this device as I forgot how complicated the root exploit was. But I went ahead and downloaded the latest stock .kdz (20g), LGUP and the drivers and proceeded as normal to flash the kdz over. I had SEVERAL issues getting my device model to be recognized and finally grabbed the right LGUP version that worked. I proceeded to flash the kdz when it gave me an error round 31%. I did much troubleshooting research and came up empty, finally decided to try flashing the stock version it was on (20a) to just restore it.
This worked. I thought I was saved until the phone froze on the T-Mobile logo while booting and didnt budge for an hour. Much more googling and I found a thread that looked promising and seemed to help. At first. It flashed the kdz, gave me the error, and when I tried to flash the dz, nothing. I retried LGUP with 20a stock, unknown model. I tried to go back through the whole rooting process again and stick it out with minimal service. The FWUL/lglaf portion of the guide is where I got stuck. My device would not be recognized in FWUL, I couldnt get wifi so plugged in my ethernet. And then I kept getting "USB configuration not set" and "input/output" errors, and I noticed that while booting FWUL, the step "Loading Kernel Modules" fails. So I assumed that FWUL was not loading any modules, including USB's (which explained the errors), so I booted up my own Manjaro install and cloned the same project there. Knowing all my modules work now, I still get the "Input/Output" error.
So now I'm led to believe this phone is hard-bricked. It registers as a port in Window's Device Manager, "LG AndroidUSB SerialNet" or something like that. I tried following the unknown model guide again to no avail. I'm at a loss. Whatever info is needed for debugging I'll provide. I'm dualbooting Win10 and Manjaro so any methods are viable.
Which specific stock KDZ(s) did you try to flash on your phone (full kdz name)? You need to seperate flashing and rooting as two separate tasks because from your post I can't tell if you are able to boot after flashing stock kdz or not. First, if your phone is not booting, you gotta recover from that and flash a stock kdz.
Also, try using the Dev patched LG UP from this post (thank the dev while you are there): https://forum.xda-developers.com/lg...ssflashing-t3780969/post76510671#post76510671
Try the 'Partition DL' option when you flash and select all partitions in the next window.
Once you are able to boot a stock rom, you can try using a VMWare such as virtual box, install/mount FWUL in a virtual environment and use that to root the phone. I think the process is somewhere here on the runningnak3d's guide or on another post, I will try find a link later.
