First, I searched and read all relevant threads concerning this issue. The five threads that showed up in the search did not help me solve my issue.
So on to my problem. I can no longer flash any rom onto my device. I attempted to flash the first official CM10 nightly (which I recently found out was not flashing properly for others) and had no success. I simply got a black screen and nothing more. I eventually got back into TWRP (v2.2.1.4) to try and Nandroid restore, but I noticed that /data was not formatting and the restore failed. Every time I would slide the bar across to confirm the restore TWRP would reboot itself. I then flashed CWM (v6.0.1.0) and the same problems were there. After that I flashed an earlier version of TWRP and successfully restored the backup. I'm not 100% sure how it was successful. So I decided to try flashing another ROM and no go. Same problems. Anyone have any ideas? When I was using CWM I got the error message below.
Code:
E: unable to locate volume information
E: unable to open ums lunfile '/sys/devices/platform/usb_mass_storage/lun0/file'
E: unable to format data
I'm running Bugless Beast with Motley #219
I'm having similar, if not identical problems. After flashing TWRP 2.2.1.4, I tried flashing a rom and gapps; the tablet would boot endlessly into recovery. Nothing I did would do anything, so I flashed the stock image to start over. This time, I used CWM 6.0.1.0 touch to make sure that it wasn't the recovery that was causing the problem. However, now after flashing the rom and gapps, instead of booting into recovery, I got stuck at a black screen and had to hold the power button in order to get back to the bootloader.
Now, like you, it seems I can't flash any roms anymore. It's frustrating to say the least.

There is a bug with the Nexus 7 where you cannot access the recovery through the bootloader. To fix this, boot up into the bootloader on your nexus 7 and, without doing anything, plug it into the computer you used for rooting it and then select the option Restart bootloader and press the power button. Once it gets you back into the bootloader again select Recovery mode and press the power button. It will now get you into the recovery and once you're in recovery you can unplug your tablet from the computer. Note that this fix is not permanent and you will have to do this every time you wish to access your recovery via the bootloader (and this problem is not relevant to the OP's problem).

Thank You Very Much!!!
I am having much the same problem as the OP. I finally rooted my Nexus 7 using WugFresh's Nexus Root Toolkit. It seemed all went well. I chose to use TWRP in a first attempt to install a ROM (I was on rooted stock), and following the instructions for installing my chosen ROM I went into it to wipe cache, Dalvic Cache and data. Both cache and dalvic cache wiped without issue, but when I attempted to wipe /data TWRP simply reported that it failed. With that failing, I did not attempt to install a rom. I was still able to boot out of recovery, but even with repeated attempts wiping data always failed. Is any one aware of any solution or have any suggestions. Thank you!
I've looked around and couldn't find the exact thread to where I can go back to factory stock.
EDIT: Now it's soft bricked.... great
Someone please help.
It's unlocked and rooted, but I have seemed to clear out the OS so now it won't load past the Google screen. I've tried everything, but adb won't recognize my nexus 10. And I am on Windows 8.
Are you able to go into recovery
Have you done a backup , maybe you can do a restore
Press power + volume
On my last flash , I had the same problem, and I was able to at least reload
The backup, reread the instruction (went on you tube , and tried again from
Scratch (redownloaded both ROM and gapps) , I think I did factory reset
Wipe cache and Dalvilk, and installed ROM and Gapps, rebooted system...

what rom you have when you softbricked it? are you able to boot into recovery? always do a nandroid back up or you will be screwed.
Was having problems with Google play store so I factory reset from phone and not twrp and was stuck in twrp bootloop.
Then I flashed H918 deodex rom to fix it and now I'm stuck at LG Startup screen. Help please. I cannot afford another phone. Sucky military pay ((

did you do a backup of the stock rom? go back into recovery and just load the backup.

Did you re-run the Superuser zip after reflashing the rom? Some roms don't do that automatically and leaves it up to you. Also havent read up on it, but can you flash a rom from 918 to your model? If worse comes to worse im sure you can use LGs desktop tool to restore to factory and start over.
Yeah i know how you feel about the military pay ? im active duty army but not for much longer!

You need to boot into twrp via hardware keys then factory reset. I did this a while back. It was frickin killing me. You need to power off or pull battery. Use the hardware keys(power plus volume down until lg logo appears then release power for one second repress it until you get the white reset screen) to boot into recovery. Hit yes twice. Factory reset. Restore your backup if you have one the reboot system..

I'm in same boat for same reason with my US996. Factory reset from withing system. The problem is TWRP intercepts the request, and does not complete it. Even if you do it (factory reset) with the button combination. I have tried to wipe all and restore my TWRP backup (all partitions except sd card), but it remains in the boot loop. I also tried to flash a H918 rom, but the installer errors with what amounts to "wrong device" error. So stuck until I can track down a stock US996 installable file.
flashed boot.img and system.img and now when im ready to reboot it says NO OS! are you sure you want to reboot?

My experience was I restored a backup and reboot. It kept booting to twrp no matter what. I could access download mode and fastboot but those did nothing. I reflashed recovery while in twrp restored backup and it still kept looping. I then at my wits end entered twrp by doing what I explained. I used the hardware side and rebooted system after that. You might try reflashing recovery img via twrp then try using the hardware keys to enter twrp and reboot from there..

Pretty sure that's normal to say that after flashing a system img.. Could be wrong but I'd wait for a confirmation.
im stuck in TWRP loop as well accidently deleted my restore point US996 as well anyone have a spare restore point they can share?!?!

I kept at it (twrp restore of previous backup) and finally got back into workable state. After twrp restore I had to also immediately flash a super su.zip. The first reboot went back to recovery (twrp) but instead of panicking and messing about I simply had it reboot system again and it came back up normally.
I found that my twrp backup is not truly clean stock so I'm done messing about until a clean stock for us996 shows up.
Yeah i got mine booting but on the main screen notification bar says Android is upgrading when it finishes my phone reboots

Its now looking for stock boot image which on yours is currently modified with system rooted.
Try using lgbridge to repairs your boot image or if you have it flash the stock boot image using fast boot command or do a factory reset while in twrp then flash entire stock image with lgbridge.

Yeah none of those work. The OS is setting off some sort of flag that states it must go into recovery and wont stop going into recovery until that flag is changed which I assume is done by the update. I tried updating with UPPERCUT/LGUP and it errors out at 4%. So right now it's still stuck
It didnt install the update
type
Code:
fastboot erase fota
from bootloader and see if it boots after that.
This will for sure fix you up...
https://forum.xda-developers.com/v20/how-to/how-fixed-bricked-lg-v20-t3501310
listen to me2151
delete fota and then pull battery and reboot.
ota's downloaded to the fota folder will cause endless twrp loop.
freeze ota in system/privapps to avoid this again.
Sorry to post on here, but maybe we can get a few tips from each other.
Im also stuck at TWRP. I installed a ROM and went back and forth between both ROMS. After about 4 times of going back and forth between ROMS, my pattern didn't recognize on boot with my original backup and daily. I tried my pattern over 10 times and it wiped everything on me. The strange part was I was swiping my pattern 100% and it failed. Also, my tries were going up and down. It would say I have 6 tries left before my phone wipes, then I would stop anjd turn the screen off, and the screen would say I have 3 tries left, then 5 tries left. My tries were inconsistent, and it finally wiped everything.
I am now stuck on TWRP with no luck of restoring. I flashed the vs995 boot image and system image and it goes back to TWRP. I factory reset, wiped everything, made sure the system folder was clean, then flashed both images again and the same thing, no luck.
I also tried to restore with LGUP, but keeps stopping at 9%. I extracted the dll and copied it into the common folder and I get the same thing.
Error: Error Code = 0x2000, Flashing Fail
When I plug the phone into my computer it shows us996 and not vs995. Strange.
Any help would be amazing.
EDIT: Figured it out!
So, I extracted the dll file from the kdz file and I had to replace it with the one in the common folder. My error was not renaming the file, so the LGUP would stop at 9%. Make sure you pull the file, rename it, remove the old file from the folder, and flash on LGUP.

I used partition dl mode to flash the stock oreo rom over 7.0 to keep the root. Then i flashed custom kernal for stock 8.0 but it didnt work. I have done the same procedure before and it has worked like a charm. But it keeps on giving the encrytion error when i try it now

Odd. If I had to guess anything, it would be that not all the partitions were flashed when going from Nougat to Oreo.
I once flash a Nougat ROM from an Oreo ROM and I had the same encryption issue and lost everything.
That was the last time I would trust myself again and not do a backup.
Flash stock recovery from KDZ through patched LGUP & do a factory reset .
After stock recovery completes the wipe do a battery pull, flash TWRP via fastboot, format data, flash Kernel & Magisk & you should be back on track...

I tried that as well. With stock recovery is says data is corrupted and doesn't do anything. I think it might be a problem with patched lg up because when i use normal lg up to flash oreo it works. But I cant root then.
I would try changing to 3.2.3-4 TWRP and then trying the procedure again. It seems that the 3.3.0 TWRP does not decrypt properly sometimes.
In the same boat as OP

Hi
Looking for a way to keep TWRP and root ... any help appreciated
I've got a US996 with the same issue as the op. I have the latest TWRP 3.3.1-0. The phone was working fine until I upgraded twrp but I might have done a mistake resetting phone outside of twrp.
I can still get back into twrp but I haven't been able to install zip files without getting that decryption unsuccessful message when booting to system.
When getting back into TWRP using hardware buttons sometimes there is a prompt asking "keep system read only?" which I never chose and swipe to allow modification. I think this happens after
I pull the battery after getting the decryption unsuccessful message. There is a reset system that I could chose under the decryption unsuccessful message but I'm assuming that will make me lose twrp
...but if my phone is a us996 and is still
unlocked, would it matter if I did select it? Wouldn't I be able to reinstall twrp using adb again on a computer after Oreo is reinstalled?
To do Prowler_gr's suggestion which guide do I follow (sounds like I should do the second option)
"Flash stock recovery from KDZ through patched LGUP & do a factory reset .
After stock recovery completes the wipe do a battery pull, flash TWRP via fastboot, format data, flash Kernel & Magisk & you should be back on track... "

Don't blame me if this goes wrong but I'm pretty much 100% certain that you mush press the rest button. This has happened to me a few times I'm sure. You won't loose twrp. Whatever resetting goes on in the background I don't think it's an actual Factory Reset.
Edit: Just to be clear you taking about a white screen with I think in dark blue or black text ENCRYPTION UNSUCCESSFUL and something like "reset phone" option directly under it, on the upper half of the screen?
Hi ezzony
Yes you are thinking of the right decryption unsuccessful page. I get it when booting to system
after installing Oreo and magisk 19 and having wiped everything (format data too). I will get the exact wording of it tonight
Thanks!
