TWRP unable to mount /system - G2 Q&A, Help & Troubleshooting

Hello
I already saw 2 similar posts/questions but nothing seemed really to help, people just somehow managed to make it work. miraculous
I have a backup so i restored after having this issue without any problems. But still I want to use my custom ROM
Coming from Rayglobe 3.2 I updated to the latest TWRP x.x.3.3. (i think), however. When wanting to flash the ROM, it says in the console that it was unable to mount /system. In the mount setting I can't click on /system neither.
It stays in a loop, saying it is flashing the ROM, but nothing happens.
I know how TWRP on G2 can take forever, especially when wiping. But this is a real loop as far as I can tell. Since I updated TWRP, wiping doesn't take much time neither.
Did anyone have a similar issue and/or a solution?
Thank You

Bootloop on Lollipop Stock

So, yesterday i tried to install Euphoria OS on my phone, but in all of a sudden, the /cache partition corrupted, i was dumb enough and deleted it via TWRP, making my phone fall into the QPST status.
After fixing it, i proceeded and reflashed KitKat, but the phone only shows 8GB instead of 16GB, so i tried to fix this by flashing TWRP, everything went well, until i upgraded to Lollipop again.
It always bootloops no matter what i do, i really need my phone with my 16GB of storage back, it isn't a Hardware failure since the QPST diagnosis didn't say anything about mobo failures.
I can mount all the partitions, i can wipe it all, i can boot into bootloader and recovery, i can do basically everything but booting the system.
Any light on this? it either happens after i flash TWRP or after i try to root it.
Im running Android 5.1.1 stock.
List of tutorials i have tried (In order): http://forum.xda-developers.com/nexus-4/general/wip-unbricking-nexus-4-using-qpst-t2208289

Don't you dare tell me to reflash the ROM again, this is the first thing i have done, i did this 20 times already and it never worked. It isn't a ROM problem. It is a partition problem somewhere.
Fixed, had to use LGNPST to reflash JB 4.4.2, then upgraded to a ZIP version of the Lollipop ROM, then flashed the stock one.
I'm having the same problem with my Nexus 4. I read also about LGNPST, but I remember something about flashing the Optimus G cache partition I believe, then manipulating one of the prop files afterwards in order to get your 16gigs back. The problem is that all of the files needed to do this flash are attached to a stupid downloader site and so its full of pop up windows and adware from what I've seen. I can't get mine to boot into system, or bootloader, or recovery, etc. The device will not finish looping for debugging to be enabled, and even trying to boot into download mode is not happening. I've tried all I know to do, especially considering fastboot and adb both utilizeusb debugging. I really am baffled. Any root kits I've tried also don't work so far. Help please.

Help Needed: Recovery Issue SM-t230nu

The first issue I started to notice after rooting via Odin & TWRP was when trying to flash the iOS and WP ROMs from this thread, http://forum.xda-developers.com/android/software/3oss-project-samsung-galaxy-tab-4-7inch-t3081478 , it would fail. I was able to successfully flash the Google ROM from same post. I believe it was with one of the other ones that it even said successful yet when i went to reboot said no OS installed. So, I figured update my TWRP to newest version, maybe that was the problem. Well after updating, now when i go to wipe/factory reset it either says unable to mount or it doesnt even make it that far and reboots system. I tried flashing PIT file with Odin and issue persists. Everything still works smoothly but any help fixing this issue would be much appreciated as I do not want to dirty flash anything. Thanks in advance.
So now...after flashing stock firmware, it boots all the way to nook screen (right after samsung logo) and stops. I can boot into TWRP but it still says unable to mount data. Also, in TWRP when i click mount, the only one already checked is cache. I can manually select all others except data. When i go to install, the internal sd has absolutely nothing on it...really hope i didn's completely mess it up, sometimes my eagerness to learn gets the better of me. Thanks again for any help!
I have the same issue, im stuck

Dirty Santa and Restoring From Backups - Suck in some kind of limbo?

So I would have asked this question directly in the DirtySanta thread, but apparently I don't have enough posts to actually do anything there yet.
So my device is now in a rather bizzare zombie state. I did manage to get my device fully rooted with TWRP installed. Followed the instructions on how to get everything working with no problems. I ended up wanting to try to flash some audio mods (V4A and such), however they did not install properly, so I went and did what anyone else would do - restored to a full backup I made of the device before I started mucking about.
The restore did complete successfully, and I still have a device that has a working recovery, and an OS with root permission...but I can't flash anything anymore from TWRP. TWRP is unable to mount the /system partition after the restore, and seems convinced that I have no OS installed, even though there is one and the phone boots into it just fine. The restore I'm on now is post-flashing the Konverged Kernel. Attempting to restore to an even earlier backup (one I made just before flashing Konverged) produces similar results - the restore succeeds and produces a bootable phone, but TWRP still can't flash anything.
Just to cover bases I also tried running "fastboot flash recovery twrp-3.0.2-1-us996.img" again in case TWRP got messed up (trying to get the "Swipe to allow system changes" prompt to reappear - it didn't), with no changes - TWRP still works fine, but cant mount and edit /system and still claims I have no OS installed when requesting a reboot.
Any advice on how to get things working again would be greatly appreciated! Thanks!
This may be an issue with TWRP. When I had my Galaxy S3 rooted back in the day I would have this issue, also with a Nexus tablet I rooted as well. It turns out I needed to flash a specific "fixed" version of TWRP to fix the mount/flash issue. That was a long time ago though, so this might not be the problem, but I thought I would at least tell you my experience.

So your phone isn't booting beyond TWRP? I'm assuming that's what you are saying. I only want clarification because you mentioned how it won't flash anything.
Try this. Go to "mount" and make sure system is checked. Then power off the device. Then use the button combo to boot back into recovery. It's power + volume down, as soon you see the LG logo let go of the power button and then press it again and hold it (never let go of the volume down button though). If done correctly you'll get a white screen asking you if you want to factory reset. Choose yes for both questions. This will boot you back into recovery. Once in recovery again go back to mount and check system again. Now reboot system. This method got me out of being stuck in TWRP after I had tried every other method I could think of.
PS. Make sure you are on a fully stock version of the ROM that came on your phone. This may work for any backup you have but just incase use the most stock version backup you have.

Sorry if I wasn't clear, its a bit confusing to me also. Normally TWRP saying you have No OS installed is pretty bad news, but it seems to be a bit confused itself, since there IS and OS installed, and the phone boots into it.
The phone basically works exactly as you'd expect after the DirtySanta exploit. It can boot into whatever backup I restore it back to, and works just fine, root included. I can also boot into TWRP just fine also..... Its just that within TWRP, if I try to flash anything at all (apps, zip files, kernels) it comes back with an error just after "Updating Partition Details". The specific error is "failed to mount /system (invalid argument)". If I had to guess I'd think that /system was somehow marked as Read Only after I did the restore. I haven't needed to use the button combos for anything since ADB and Fastboot commands all work just fine too.
If I go into the "Mount" section in TWRP "System" is unchecked, if I tap it to try to check it the phone vibrates as if it accepted the input, but the check never appears. If I select "Mount System as Read Only" I can mount it though. I followed the instructions in the DirtySanta thread to a T, and am using all the recommended software versions.
I also tried restoring back to the backup I made just before flashing Konverged Kernel, with similar results. The restore works, and the phone boots into Android, but if I try to pick up where I left off and flash Konverged again from within TWRP, it fails with the "failed to mount /system (invalid argument)" again.

I would run the dirtysanta exploit again from the beginning. Your assumption about being stuck in read only seems correct. I'm guessing you might have chosen read only on accident one time when you booted into TWRP and now it's stuck there.
Or you could try using flashfire to flash the TWRP.img
I am having the same issue. I tried doing the DAC mod that enables high impedance as always on. Audio quit working along with the stock music app. Did a restore from after I flashed the konverged kernel. And now no r/w ability and twrp will not mount system unless I check mount as read only. I was able to reinstall supersu from the recovery. But still have the issues.
Only thing I can think of is waiting for a return to stock unrooted method to Come out and re-root.

Hey I was having the same problem and I fixed it myself messing around with a few things I could think of.
Here it is pasted from another thread.
Dinked around with a few ideas and got my problem fixed! Heres what I did.
1. Made a backup of system in twrp just in case.
2. Formatted system in wipe > advanced > and only checked system.
Panicked because I thought I bricked my device, wouldnt boot farther than the lg logo,
(next steps might be unnecessary but I panicked and tried them lol)
3. still had fastboot access so I repeated step 3 in the root method.
4. Reflashed boot2.img
5. Rebooted to recovery with volume- power, release power while keeping volume- at lg for a second then repress and hold power. Yes twice to get to recovery.
6. Restored system backup. (was able to fully boot now but with lag)
7. Reflashed konverged kernel.
And everything is working perfect now and I have my r/w ability and can mount system in recovery without having to select mount as read only.

You can probably just wipe your system like I said in the previous post then Just restore it. I panicked and did a bunch of extra stuff. I realized that when I did my initial backup of my system, or said that its size was about 126247251477482716MB. So I'm guessing when I did my restore (possibly what happened to yours) that it somehow messed up the system.

I'm stumped on this (Rebooting into TWRP)

I've had this happen before on other phones, usually fixed by just installing a different rom or restoring a backup. Not here.
I finally unlocked my bootloader on the XT1607 (the Motorola site just randomly worked one day), installed TWRP & the 7.1.1 Soak Test (from here). I forgot to backup 6.0.1, so I backed up the soak test which was booting and working flawlessly. I was using it for a while, but I did a factory reset inside TWRP and it randomly said "cannot mount storage" and when I rebooted, it was into TWRP. It wasn't working at all, so I got LineageOS 15.1 and flashed that. Same error, "cannot mount storage" and back to TWRP. I went into Wipe>Format Data and then reinstalled Lineage. The "cannot mount storage" error was gone, but still booting into TWRP. I tried AOSP Extended, CyanogenMod, Paranoid Android. roms with gapps, roms without, with & without supersu or magisk. Nothing worked. So then I thought that restoring my backup (of all partitions) would fix the issue. It didn't, still booting back into TWRP. I'd also like to mention that plugging the phone in still worked, I can view the files in file manager, sd card works, etc.
So, no clue what to do here. What's wrong? It all started with that simple factory reset from twrp.
edit: I found that if I boot into bootloader and press start it will go into android, but hardly a permanent solution.
Same thing happened to me but my issue resolved after restoring back to stock rom with stock recovery and after that u can again flash twrp it will work fine

Heyyy, thanks man. Worked like a charm.

system keeps flashing stock recovery?

My phone was rooted for the longest time without any problems, but some time ago (I'm assuming after the Treble update) apps would not detect root, although any app that was already using root could continue doing so.
I checked Magisk, which said root was not installed. I booted my phone into recovery, and somehow my phone had the stock recovery flashed on it. I tried flashing TWRP on it again, and it worked. Except, when I rebooted my phone into recovery later again, it went back to stock recovery.
I have no idea what's going on, and would really appreciate some help.
(PS: I do know how to update my phone without the phone reverting to stock recovery, I've done it many times before, so that can't be the problem)
update: I tried flashing TWRP again (through bootloader), and this time I jumped straight to recovery. It showed all the directories as if my phone had just been completely wiped. Internal memory 0M. No files anywhere. Didn't even have a downloads folder.
In a panic, I rebooted my phone, but my phone was actually untouched, no data wipe whatsoever. I'm even more confused about what the hell is happening now.
The stock OOS will automatically reflash the stock recovery if it detects it has changed to something else.
You have to boot into TWRP right after installing it and either let it mount /system read-write (likely to cause problems later) or install something like Magisk that will prevent overwriting the recovery.
TWRP was not able to read your data partition, which can happen depending on which kind of encryption you have. Try the BlueSpark TWRP, it supposedly supports encryption better than the official one.
It's the version. If I use 3.2.3.0 or 3.2.2.0 I get no files. But 3.2.1.1 works for some reason. You can also install pie now. There is a link in the one plus 5 forums here to hydrogen os. It's Chinese version but that doesn't matter. It is in English. You will need to uninstall a few Chinese bloatware apps and flash gapps. But besides that I don't see much difference. If anything the hydrogen os looks nicer. I'll add some screenshots . Developer options was enabled from first boot, with the advanced reboot menu I noticed.
Also, if you have root the TWRP app can flash recovery from in the OS.
