Okay, so first I had problems with flashing a new ROM due to an error in opening /data/font/config and other folders in /data. So, I accidentally went on and wiped system without creating a backup, because I thought it was just a problem when creating a backup. Seemingly, this was not the case, as everything BUT Data partition was wiped. After that I tried to flash CM13, but ran into problems with installation, as the same error caused it to fail every time I tried. Solution was nowhere to be found, so I tried to flash the stock ROM using LG FlashTool, but that didn't work (I tried using the old version, maybe that was the problem). Then, i tried to use the updated method found on the same page, but accidentally went on and ran the newer FlashTool and the G3 started Firmware Upgrade. This, of course stopped at 3% because I couldn't access the FlashTool completely as I didn't have all the needed files or the info yet. I unplugged the device and now I can't boot into Download Mode, Recovery or anything since I don't have the recovery or system anymore...
The device will power on, but when powering on by pressing volume up and connecting to my PC via USB I only manage to get the LG screen with "Boot verification fail" and then just blank black screen with no notification LED. Otherwise it has the same blank screen and notification LED blinking red and blue.
Is there any way to fix the phone?
P.S. This was the guide I used when trying to use the FlashTool:

Found a way. It was Qualcomm QDLoader 9008 way of unbricking it. The device works flawlessly now. Here's the guide I used: http://forum.gsmhosting.com/vbb/f49...ts-fix-qhsusb-bulk-_-qualcomm-9008-a-2029025/

Hello all,
I've done a lot of googling and searching on these forums and I'm having no luck. Hopefully by asking I can get some headway.
I was attempting to restore to stock rom. At 17% of the process using LGFlashTool 1.8.6 the tool gave me an error 'Unable to Communicate with phone' after about 10 minutes of no progress. I exited the LGFlashTool program and ran it again and now it fails saying 'Cant' change to download mode". If I turn the phone off and then press Vol+ and plug in my cable it just goes to the Firmware Update screen. My phone *IS* detected properly in the device manager as LGE Andriod MTP Device and under ports as LGE Mobile USB Serial Port (COM41). If I go into recovery (Vol- and power) it asks if I want to do the restore - but it doesn't actually do anything once I say yes twice. Just sits at the firmware update screen at 0%.
I looked at this post (http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091) but it appears to be either for a different phone or different problem (showing in device manager as a bulk device - mine is not doing that). Frankly I don't want to make things worse (if that's possible)
Does anyone have a way that I can restore the download mode for this D852 phone? I'm hoping if I can get download mode to work again I can reflash the stock rom. I don't care about the data on the phone at this point.
I'm willing to send some $$$ via paypal to whomever can get me back up and running! Thanks

What happens when u just power up the phone ?
Thanks for the reply.
If I shut the phone down (by pulling battery) then plug it back in and just power it on, I get the LG logo then it goes to the firmware update screen with 'USER B84" in the box below the progress bar. Progress bar never moves. I get to this screen whether I start it in recovery (which is just the factory recov - looks like during the initial 17% it wiped out my TWRP), attempt to start it in download mode (I do not get the download mode screen with the blue dots anymore), or regularly by just holding the power button.
ok
Dont plug it into the computer and try to power it up what does ot do?
Same thing.

Ok that didn't work for me but I did try the LGFlashTool using Board DL instead of Upgrade DL and it was moving a bit. Finally got to 10% and failed at 574 sec with the error "We can't communicate with Phone". I am using the cable that came with the phone. It isn't damaged or anything.
Here's what is shows in the LG Flashtool window (this is port 1 (com41)
Code:

On the phone it shows COM41 under the usb icon on under firmware update and 0% progress. In the box below it says:
Code:
F USER 50.0 A50.0 B70 UHS
S U LG-D852 04.4.2 Hrev_10

D85210b
That's it. Should I leave the phone connected at this point or unplug it? Device still shown in device manager (have had it up beside the LG Flashtool window the whole time. I do see it refresh from time to time but the contents dont' seem to change at all.
Ok so I left this over night and when I checked the phone this morning it's different but I don't think it's good.
Looks like it proceeded but ended with:
FBOOT Check
FBOOT Complete Time [0s ] 1th try
Factory Reset Flag = 2
Factory Reset Flag Check Fail!!!
And my phone has a blue screen with Factory Reset Status and a big red '2'
Now what do I do?
Some further information.
If I run the LGFlashTool in Board DL action mode, it seems like the process works but I end up with the red 2 on the screen. But I don't get 'can't change to download mode' or 'cannot communicate with phone' errors.
However if I choose Upgrade DL action mode, then I get 'can't change to download mode' or cannot communicate with phone'. ARGH. What gives?
I have tried things like fresh restarts (restarting PC), restarting the LG FlashTool between attempts, not restarting flashtool, etc. I can't seem to find the sweet spot.

http://forum.xda-developers.com/sprint-lg-g3/help/fix-bricked-lg-g3-ls990-stuck-fastboot-t3084562 another tutorial to try
Thanks, but no dice.
I don't get fastboot options, and if i download and attempt to use fastboot, it shows no devices.
Also, when following the steps for the BOARD DL option in the lg flashtool, it goes through the process but I get no ATT screen. Nor do I get the option to tap OK or Normal - as soon as my device reboots after the flash, it gives me a MINI OS (iirc) screen with a bunch of vertical bars below it moving up and down then it changes to the Factory Reset screen with the number 2.

http://androidforums.com/threads/ho...-2-lg-g3-d855-twn-32-gb-problem-fixed.911271/ i found one more that could help it said to use a jdz not a tot hope it helps if not sry
Thanks - I'm going to give this a try, however I can't finda .kdz file for my phone (canada/rogers D852 LG G3) - the links in that post that link to firmware is for a tot file. Does anyone have a link to the KDZ?
Hi, I'm having the exact same problem now, where the phone only boots to the Firmware Update screen. Did you manage to fix it?
Indeed.
I used the KDZ method pacods61 posted last, but I had trouble actually finding kdz firmware. With some help I finally managed to do so from here: http://devtester.ro/projects/lg-firmwares/country.php?country=Canada
Direct link for D852 Rogers Lolipop 5.0.1: http://csmgdl.lgmobile.com/dn/downloader.dev?fileKey=FWF448V332CPAKX8CEA4UCE/D85220g_00_1205.kdz
Current situation: I'm currently stuck at the "firmware update" screen when I turn the device on.
What I think I did: I think I messed up the partition file or made a mistake trying to install twrp custom recovery
What happened: I did a factory reset when I got confused at one point and that worked as it should. When I tried it again, I was stuck in/at fast boot. However, doing a battery pull would boot the phone up. Recovery was damaged somehow?
I tried putting the phone in download mode to flash it to fix this issue. I did the method where I change COM5 to COM41, use flashtool to flash a tot and dll, pulling the usb out and reinserting when the program says "ready" but I get an error: Partition Change fa00000064 and hence that process fails.
LGPCSuite doesn't work.
Any idea how I can rectify this issue?
Thanks in advance.
So after accidently wiping everything I had on both SD and Internal memory trying to make a custom rom work, I was stuck with a phone that only has TWRP on it, basically. Now after I've been through this guide TO THE LETTER: http://www.droidviews.com/install-stock-android-marshmallow-lg-g3-d855-using-twrp-recovery/ I can see it installed an OS but I cant seem to get my phone to load it! SO then I tried entering recovery mode and getting back to default, it didn't change anything, so I tried installing Zoe rom (https://forum.xda-developers.com/lg-g3/development/zoe-rom-v1-0-mm-6-0-stock-v30a-d855-t3402087) and It STILL ONLY LOADS TWRP even though the installation seemed to be successful!
So what do I need to do? Just flat out delete TWRP? or what? Pleas advise as I'm desperate. If needs be, redirect me to how to just completely reinstall everything from scratch to 6.0 or 7.0 (preferably). I was on 4.x.x for ages and I just wanted to update, instead destroyed my phone. Sigh.
UPDATE: Another thing I've tried is to flash it with KDZ file from the PC. I can see the phone, I can transfer files to it, but windows DOES NOT recognize in the device manage so when I tried to use the flash tool, after clicking "Start" it pops a new window which gets to 60% and then stops saying the phone is not connected to the pc.

I just got over something like this this morning. First, you need to ensure you have the LG Universal drivers installed for your phone. Get them here.
Next, reboot your machine.
After this, I made sure the PC recognized all 3 modes of my phone, TWRP mode (boot to TWRP, connect), Download Mode (boot to download mode with cable) and, at least in my case, the flashing lights mode (shows up as QHUD Bulk or something).
After that, I ran the KDZ restore program successfully.
Good luck and let me know how it goes.
Hi,
my OnePlus3 is dead.
Nothing to see on screen, no vibration by pushing the power button.
Tried to unbrick it with UnbrickToolMini. It startet one last time after hours, but failed to boot because some parts ar missing now, system failed, recovery failed, boot failed.
I do not dare to use UnbrickToolFull from June 2016 with OxygenOS 3.1.3, because it is now OxygenOS5.
Is it possible to exchange the firmware in MSMDownload Tool ?
There ist some data on the phone I do not want to lose.
Or is there any other possibility to flash the firmware without data wipe?
Thank you!
Best regards,
Nicole
I doubt that since the userdata partition will be wiped on your phone, no matter what the files in the MSM Download tool.
The os version is irrilevant, the tool doesn't just flash an OS, it will return the device to factory status, so i dont think ita a problem using it
Ok, I have done that, but with the mini ubrick tool I can not boot into recovery, the phone goes off after selecting recovery mode.
The full unbrick tool removed the data, although the guide says "remove all userdata* from rawprogram*"...
But the phone gets booted sometimes. Then touch is not working anymore. And if I connect it to to the pc, it turns off or reboot into a bootloop.
Most of the time it does not turn on. I push the button for hours and the phone goes on only twice.
Any suggestions would be nice!
Thank you!
Best gegards,
Nicole
Use unbrick tool full , boot then download latest OOS 5.0 and put in internal storage update to latest. I'd done this way.
I used unbrick tool full. If the phone turns on and boots, I can not touch anything on the display, it is not working. And if I connect it to the pc, it turns off or reboot into a bootloop.
So how should I copy the update to the phone?!
I do not understand why the phone is rarely turn on...
Makes me crazy. Never again a OnePlus!
Download again the full unbrick guide and flash again. If it's not working your phone have hardware problem.
Hello everyone reading! I've tried many guides here, but none seems to work for me somehow, thats why im writing this post.
Whats my problem?
- I've been having this problem for a year or so now, like most softbricks im stuck on a bootloop while launching the phone, with red and blue led light flashing.
The message displayed in the top left corner of the screen says:
boot certification verify
Secure booting Error!
Cause: boot certification verify
How i have bricked my phone?
- I remember i have tried to unroot my phone after having cm installed, can't remeber the version though. Then the phone just got stuck in the bootloop and wont launch along with recovery.
What have i tried?
- I have tried flashing the phone to stock via lg flash tool (tot and dll) and Lg Flash tool 2014 (kdz) no luck unfortunately.
- While flashing stock F400L rom through tot files im having sometimes Milkyway connection failed error when im launching the program, but i don't think that's the case.
I'm doing everything in right order, drivers and programs installed, going into download mode, changing ports to COM41 or COM1 (neither works), launching lg flash tool 2014,
choosing suitable for F400L stock dll and tot then launching the process, unplugging the phone and after 5 seconds plugging it again.
Nothing happens, im stuck at ready.
- Tying to flash through kdz file seem not to work either, got errors after l start the flash process.
Phone plugged, in download mode, yet i get the message of program not being albe to access it, like it would have problems with connection to the computer.
Im following the instructions that program gives me though it does not help at all. It stops after reaching 4% and asks to connect the phone back after checking connection with the device.
Thanks for any help provided!
