TWRP not mounting /system on startup - T-Mobile LG V10 Q&A, Help & Troubleshooting

[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?

[Q] Help with supposedly bricked phone

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.

[Q] Unrooted Phone Will Not Boot

Hello, everyone! I'm in search of a hero who can help me resolve this (frustrating) issue! I'm sure you have heard it before: my phone will not boot fully; it is instead stuck permanently on the white VERIZON logo screen.
Model: SCH-I545
Carrier: VERIZON
Color: BLACK
Size: 16GB
The phone has not been rooted.
It does not have USB debugging enabled.
I have not installed any custom recovery software or mods.
There is no external SD card installed.
First, some back story. My phone asked me to perform a software update roughly a week ago. About a minute into the update, it told me the update failed. I assume this occurred because I was on the train and passed through a tunnel. Afterwards, my phone began acting up, rebooting itself randomly, and applications(such as web browser, text messaging) would randomly crash on me. I assumed another update would come to resolve the issue, but unfortunately yesterday(Sunday), my phone again rebooted itself, only this time it would not make it past the white VERIZON screen.
My goal is simply to recover my files from the device before either returning it or performing a factory reset. I have scoured the internet for hours trying to find a way to achieve this. I can boot my device into the stock recovery console and into ODIN download mode. I have tried clearing my phone's cache in recovery mode, which did not help. I have tried booting into safe mode by repeatedly tapping the menu screen, but it did not help.
I have ADB installed and a USB driver from Samsung and a USB driver from Google. I can get my phone to appear using ADB in sideload mode only while in the recovery console. Unfortunately, this is of limited use because apparently it can only be used to install software packages, and the phone seemingly rejects all attempts to install packages such as CWM and TWRK, which I had hoped would allow me to use the ADB pull command.
I have tried installing these mods using ODIN as well. Again, failure due to security apparently. :crying:
If anyone has any idea how I can retrieve the files from my phone, you'll be my hero forever!

Sounds like that upgrade definitely went wrong. Since you were upgrading to Kit Kat I'd say flash the No Wipe file from here http://forum.xda-developers.com/showthread.php?t=2735172
Your phone won't allow for CWM or TWRP recoveries since it's a build past MDK. Also if you want prior to using that Odin file go to play store and get the app " Samsung phone info" and run that app and take a screen shot of the bootloader section. Actually do that before hand anyways. I'll link you to it

hopefully people will learn by this NEVER take any update while traveling, too much can and will go wrong.............
Yea I think people have to much faith in Verizon. There not setup to handle anything but a perfect download and install when it comes to their OTAs. They're best done on WiFi at home

Hi BeefJerkyAddict,
I would reccomend to do a total full wipe with Odin, this usually solves all of your problems. All of your stuff should be clear for restoring once you do that. But after you do the full wipe, immediately go to settings and then software update because your phone will be on android 4.3 and not 4.4.2.
Here is the link with the instructions as well:
http://forum.xda-developers.com/showthread.php?t=2578209
You're welcome.
Yea I guess I'm just biased to updating straight to kit kat lol if the op has the chance to stay on mk2 he might as well. And I suggested no wipe first just so not to lose data. Up to the op though

Hi guys,
Just posting to say THANK YOU for the help. After a long download, I got ahold of the VRUFNC5 No-Wipe file and successfully installed it using ODIN3 v3.09 without a hitch! All of my pictures, videos, text messages, are all right where they were, and my operating system is upgraded.
Thank you so much for taking the time to point me in the right direction. I had nearly given up!

Stuck in Download Mode, crashing during recovery

So I was having so many issues with my rooted phone crashing on jasmineRom 7.0 I thought maybe an OTA update had made it through and started downloading. No matter what I was doing the screen would turn blue and then restart. Sometimes it would crash blue again during reboot, and sometimes it would crash and then show the green demigod crash screen. So I researched flashing the .tot files to go back to stock. KDZ I didn't care for because it still showed the phone as modified software, and I wanted full stock so I could use the extended warranty with Verizon if need be. I eventually got the .tot method to work and everything was hunky dory, and showing stock. I upgraded all the way to marshmallow and decided I love every bit of it, but I couldn't figure out how to get my contacts and stuff off titanium backup without root. So I figured, "well roots not the problem if an OTA tried to download it just means I missed a setting or something". So I rooted again. No issues, I reinstalled JasmineRom 9.1 this time. Eventually it started crashing again, although this time I followed absolutely every guide I could find on disabling OTA. So I thought, "Great it's Jasmine" and I really wanted Marshmallow anyway so I followed xdabbeb's guide for getting the 35b bootstack on my phone, worked great no issues, and then I installed xdabbeb's firmware, combined with Edor's debloating zips. Everything was working great! I had no issues, I backed up just my apps, and some data, and reinstalled others and everything was great and working fine, and the phone was still official, no OTA's getting through. That was almost a full week ago. Yesterday I woke up and the phone wouldn't turn on. I took the battery out and put it back in and the phone came on, but then crashed with the blue screen again. So I thought great I guess I'll put it back to stock and use the warranty. By this time though I was having trouble getting it to load past the LG screen. I finally got it into TWRP and was able to wipe everything (except SD card) and then I stuck it in download mode and went to install the .tot files. Weeeeelllll, long story short, it crashed during download mode install with the LG Flash Tool. So now the phone gets stuck in download mode everytime I pull the battery and power it on. And crashes again every time I go to install anything. KDZ doesn't work, the flash tool says it can't communicate with the phone, because it crashes. And LG Flash Tool for the .tot files seems to crash everything it loads the modem, or consistently crashes on LAF:bin_user_mode. So I have no idea. At the moment it just looks like my phone is all funky defective, and Verizon may take it back and give me a new one so I'm going to try that. HOWEVER! If anyone has any ideas on what the issue is or what else can be done, I still want to hear it. Feel free to post
Also I've tried updated drivers for the computer, I've tried rolling back drivers, I've tried different KDZ files, I've tried the LGUP8974.dll fix where you flash that in flash tools and then flash the vs985 dll, which is what I had to do to get it back to stock the first time. I've tried everything I could find online except anything to do with fast boot and shorting the pins. Which I haven't tried because I can still access download mode it just seems to be stuck in download mode. Those methods from what I understand are for hard bricking, and for people who's phones don't turn on at all. Although if Verizon won't help I may try one of the laf recovery methods.
Thanks!

LG V10 Bricked (sort of anyways)

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
http://forum.xda-developers.com/showthread.php?t=3440359
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.

LG UP V10, can`t get it to work.

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.
