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 everyone,
Last month I rooted my LG G2, and installed cyanogenmod. Everything was going smoothly but for some reason I decided to restore my phone from a backup I made before installing cyan and then just continued using it like that. Two nights ago an android software update took place automatically overnight and when I woke up it was just stuck in the TWRP menu. I tried restoring from previous backups, wiping it and re installing the cyanogenmod that was still on the virtual SD card to no avail, and finally completely formatting the phone to see if I could get it to show up on the computer because it makes the connection noise but it doesn't show up as a device or hard drive.
So now when it boots up it shows the LG logo and then brings me back to TWRP but now I have no restore points on the phone. So is there anyway to get my computer to recognize it so I can add files and hopefully get a working backup on the phone? Or is there a way I can even just flash the stock firmware on it again? Or am I out of luck?

so you formatted your sdcard too. (jokes aside, thats genius). Mind my sarcastic fun-poking, you will have to put your phone into emergency mode and use a tool to flash the stock rom. Usually you can navigate to the manufacturers support page and they will have an updater tool that can flash one of the updates. if not, then scour the forums for an unbrick guide that will flash the stock rom from emergency mode.
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 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
[SOLVED] My LG v10 is in a bit of hiccup because of this. I have tried multitude of things with still no solution.
I have attempted to go into the mount of menu of TWRP and mount the system, after mounting I have tried everything from reinstalling a rom, wiping it, resizing, restarting to system, a few terminal commands, and they all lead to same exact scenario. The phone restarting, flashing the lg logo for half second than going to "this device software cant be checked for corruption" yellow triangle screen till TWRP comes up.
I have also tried 3 different versions of TWRP, installing kdz files, using an lg bridge/up update, and also some prayer. The only thing that has ever gotten me close to getting this baby back into shape was the lg bridge software update in download mode. Brought it to full startup from system but than ended on a white screen asking for a password 30/30 attempts to get into the phone, and I don't have encryption and even if i did it would be gone after the numerous factory resets and data wipes.
Are there anymore possibilities for me to try? The problem seems to be the system partition not mounting in most cases but I seem to have a reached a dead end.
Edit 1 w/Solution:
What ended up solving the problem (bad firmware, anti-rollback stopped me from going to a good one) was the following post by tungkick (THANKS TUNGKICK), once I got the microsd card ready and in the v10 I than put the phone in download mode (volume up + battery + usb to comp).
From there I used the lg bridge tool to detect the phone and than update back to stock. The key thing is i didn't chose the regular update option I chose the option on the bottom right (of my lg bridge application) that said update without error recovery I believe (sorry updating this away from home so I can't remember exactly). Once the update was done there was no screen with asking for a password, no bootloop, and so far no problems with the stock software.
Hopefully this is helpful one day to someone with a bricked v10 and almost gave up hope like me.
That happened to me when I tried rooting, I flashed the latest official kdz (select update) to get the official stock rom again

Tried that and flashing tot files, feel like I cant do much unless I can install the /system partition on start up or get through the anti rollback settings.
As of now I can use twrp fine and get in download mode. But that seems to be it
Dunno what to say, do you have the latest version of lgup?

Hello everyone, I have been a fan of your forums for quite a while, you guys have an awesome community. I have been attempting to unbrick my VS990 with no success, I have LGUP and all of the proper dll files in the proper folders, I have two .kdz. One is the stock kdz, I can not get to work at all due to anti roll back (no matter which option I choose) and the other is the current kdz. I got that one to accept using update, but it did not fix my phone, it is still stuck in boot loop. and using refurbish I get an error message saying that it is not supported by that kdz. LG UP is fully recognizing my phone, I found the .kdz files no problem, I believe that I have followed all of the steps here >> https://forum.xda-developers.com/lg-v10/general/guide-lg-v10-stock-firmware-to-stock-t3224170 any help at all would be appreciated. Side note, I have not rooted or installed a custom recovery.
I would also like to add, I can not do a hard reset. Every time I attempt the phone either locks up when I hit the power key on yes to confirm factory reset, or sometimes it reboots to LG splash screen and locks up then. I am starting to wonder if there isnt a hardware problem with the phone instead of software.
