If anyone can advise me here I will be very grateful. I have spent several days looking online and reading countless threads here but am still not having any joy. Am a bit of a noob so go easy on me please!
I have a rooted LG D618 running Lollipop (recently upgraded itself from Kitkat). Long story short, I was fiddling around with the bootloader trying to install a custom recovery (ahem... ) and I ended up bricking the phone. I have been trying since then to install the original firmware using LG Flash Tool 2014 and it always stops on the 4% mark whilst extracting the kdz. I have tried this about a hundred times and the same thing happens every time. The phone is completely dead, I can not switch it on and I am unable to boot it into Factory Reset mode using the keys either. But it is still being recognized by the PC (win7 x64) and can enter (what I assume is) download mode. However in Windows the phone is recognized as removable disk containing 2 folders - 'image' and 'verinfo'. Not sure if that is normal or not? I am able to start the kdz flashing process and it goes through the first couple of steps verifying connectivity etc and then stops at the aforementioned 4% during the file extraction process, sticks for a while, and then gives me an error message.
I tried a solution which I found on the forum here, which I think was for the same issue, involving the wx.dll file in C/ProgramData/LGMOBILEAX/phone but this has no effect. I thought it might be related to me installing the KitKat kdx (v10c) onto the phone but I have since tried flashing the stock Lollipop variant (v20b) also and the exact same thing happens so am guessing it is not because of the KitKat wx.dll file causing issues. I am pretty clueless here, all of this is unchartered territory for me and I am out of my depth so if any kind soul here can advise me on any possible solution I am willing to try anything before admitting defeat, and taking the phone to LG to fix under warranty and hoping they don't realize that I broke it. :laugh:

I got my LG G3 yesterday night and I tried rooting it for hours, I was on Andrioid 5.0.1 and couldn't get it to work after 6 hours of trying so this morning I tried to downgrade back to stock firmware and now everytime I try I get the Factory Reset Status 2 screen and I am told to just remove the battery and it'll boot but nope it just goes back to the same screen. This is becoming a nightmare I have tried multiple PC's Operating Systems, drivers, firmware files, and multiple tutorials and I cannot fix this.
I think the issue is when the phone reboots instead of being a COM port it becomes a MTP device so LG Flash Tool can't find the device.
I really need help, I didn't plan on spending the whole day trying to fix this but it seems I am going to have to.

In the general section, stickied, is a thread on how to do it.
I have been at this for about 4 days, and I've spent literally all day today trying to get this to work. I'm having an issue with my phone where the battery is draining really bad, to the point that I have less than 3 hours of screentime on a full charge. I've read about mods and different installments you can use to fix this, but you have to be rooted. I was rooted before via Stump, but since then have unrooted back to the default. I tried to simply use Stump again but it says it's patched. After some research I found that I should flash back to a previous android version ( 10b ) and root it from there using Purple Drake, THEN use TWRP to update back to 5.1.1 lollipop. I'm running into some serious trouble flashing my Andriod. And I think its because it won't go into download mode. I turn it off and hold the volume button up whilst I plug it into the computer, and it goes directly into "Firmware update " 0%. And it has a progress bar, with no progress change I have no idea why it's doing this or what's causing this. I've tried the KDZ method, and it stops during the progress saying " Connection to server failed, please try again in a moment ", which I read was fine and to wait for a Green word on my phone screen and some changes, however the phone does absolutely nothing and sits on that same screen. I've tried the Lg Flash Tool method too, and there was an error saying " Failed Previous Load ()". I'm honestly exhausted and if someone could figure this out you'd be a lifesaver. Speaking of which, I'll buy you a whole bag of the fricking things if you do.
Any help is soooo very appreciated.
Thank you
Howdy,
Are you using the flash method described here?
You don't say which bootstack you're on. If you're trying to flash back from 35b you need a different dll. (LGUP8974.zip)
What Windows OS are you using to run the LG Flash Tools from? (It seems like success / failure can be very OS / USB Device driver related.)
For my phone, I had to get the flash tool ready to go - have the phone in download mode - and then unplug / replug the USB cable briefly on the phone in order for the process to initiate.
If you have some screenshots, that might be helpful too...
I have been reading everything I can find and tried to figure it out myself but the more I read the more questions I have and the less sure I am about trying any of the things I have read.
My problem is with an lg tribute from the company called Textnow. My friend ordered the phone from them and was having some issue she decided to try to fix by doing a factory reset which caused it to be stuck on the Lg boot logo. I tried booting to recovery to fix it. The recovery was TWRP. I was under the impression that Twrp was a custom recovery program that was installed after unlocking boot loader. Best I can tell is the phone was already rooted by the company. Does this sound right?
I messed with it for while but couldn't get anywhere with it because I haven't any knowledge of rooting except what I read . I noticed it kept saying something about simulating actions and figured that out but now after trying to back up and restore and poking around that it says there is no os , I was hoping someone could help me figure out where to go from here as it isn't my phone and I would hate to damage it although my friend keeps telling me to just try whatever no big loss because she can't use it like it is so.
I am not sure what the phone had for firmware because I cant get it on. I only know that it had twrp 2.8.5.0 as recover not the usual android. I can access the phone internal and external through twrp and though pc and adb. I made sure to get drivers updated. I tried to flash the stock rom from its forum but it failed,. any info would be mush appreciated
Hey guys, I've got a T-mobile v10 (H90120j) on 6.0 and on the most recent update as of 8/22. I tried to root via the LG UP method, but something went pretty wrong pretty quickly(I'm sure I mis-interpereted a step or made some similar rookie mistake). I'm in a boot loop of the "Your device software cannot be checked for corruption" no matter what I try to do. Luckily TWRP installed, but when I tried to reboot to finish the LG UP method it told me there's no system. When I connect it to my computer it shows as v10, but only the TWRP folder is visible on it. I was trying to find just a stock rom zip, but the ones I can seem to find are the ones that use LG UP using tot files, but I can't get the phone to go into download mode. Then I found stuff for the h90120e, which evidently hard bricks the phone. Does anyone on here know anything about this? Its not fully bricked but since it wouldn't mount the system properly, I wiped everything and repaired the system files on TWRP so I'm on a totally clean slate now. ANY help is greatly appreciated
**UPDATE** Tried installing Bliss rom, and had no errors, same with gapps. I'm still stuck in this boot loop though; I cant get past the "your device software cannot be be checked for corruption" screen

Was this thread ever resolved for you k.wise, having the exact same issue just about with my v10.
The problem at least for me is the system partition of memory isnt even mounting and in turn is throwing error 7 and not allowing anything to be installed or read on it.
Hello guys and gals, so i just recieved my LG V10 H901 and tried to follow https://forum.xda-developers.com/tm...step-step-guide-rooting-lg-v10-using-t3382631 this guide, but eventually i ended up with a brick after trying to flash the .tot file.
I keep getting
Boot Verification Fail
- cause: MISHMATCH_SIG_LEN
The TWRP recovery i had is now gone, and i can't access Bootloader. I can enter Download though. I read a lot of things around the problem, but i always stuck on various software versions or phone versions i can't really understand. Is there any way to get the phone back working? Before i try any method i just want to be sure i wont mess even worse (if that is even possible).
I tried UnbrickMe thread, but it says only for soft version:h90120j I have soft version H90120c (i haven't performed the update to MM) so i don't wanna try without being sure its going to work.
I m leaving for vacations in couple of days and i don't have a phone :/ please give me your lights.
Also LGUP wont see the phone, the same for ADB.
OK I Fixed it!
I was able to get out of this maelstrom of bootloops and to finaly flash the default ROM (you can find it here https://forum.xda-developers.com/tmobile-lg-v10/general/stock-h90120j000712-kdz-t3436249 )
So what i did is to remove battery for 10 seconds
Put The battery in
Hold volume up button
Plugin the phone to my PC through USB
Then download mode will start
I opened LGUP and fortunately it was able to see my phone.
Then went to Upgrade and flashed the kdz file.
All went smoothly and the phone is back working.
