So, I rooted my phone following the instructions laid out here http://forum.xda-developers.com/ver...-to-notes-root-install-xposed-unroot-t3411039. I then flashed http://forum.xda-developers.com/ver...t/stang5litre-edition-5-0-s7e-rom-s7-t3453441. Flashed xposed with no issues and then later on I needed to log into snapchat so I uninstalled xposed framework. Logged into snapchat. Reinstalled xposed the next day and I can't boot my phone and for some reason it factory reset. At first the issue was it was stuck on the screen when you are setting up wifi. I tried rebooting several times and now I can't even get it to boot up properly.
Things I've tried:
The unroot method. Odin fails.
Tried factory resetting through the phones menu and it says failed to mount /system (Invalid argument ) can't mount '/system
Edit: Also tried the Verizon Software repair assistant. It fails as well.

TWRP can't mount /system. Phone is a SM-G900T 16GB
- Running the latest version of TWRP I tried:
- Wiping, repairing, and reformatting from TWRP, also tried formatting data. I get a unable to mount '/system' error message every time.
- Using Odin and Heimdall to reformat using a downloaded .pit, neither works. I ran Heimdall in Windows and Linux (ran as sudo and admin). I re-downloaded the .pit multiple times and tried a couple different sources.
- Installing CWM using Heimdall, and ADB. In ADB and Heimdall I still have TWRP and in Odin it removes the recovery completely.
- Fix permissions gives the unable to mount '/system' error message.
- Installing ROM from Heimdall and TWRM
- Mounting /system with or without MTP
How it happened:
I was running Cyanogenmod 11 with encryption and updated to 12. CM12 was running great, flashed GApps, still running good. I signed in to my Google account and downloaded IPcamera. While running IPcamera I got an email, the screen started going crazy flashing between the alert and IPcamera screen, I couldn't do anything so I pulled the battery. When I rebooted it was stuck in a boot loop. I booted into recovery, it asked for my encryption password as usual. The password didn't work. I tried several times. I rebooted and tried again, still nothing. I rebooted again and this time hit cancel when asked for the password. I wiped everything and got the can't mount /system error. I tried everything above, nothing works.
I can't download my .pit so there is more wrong than just the data partition.
Any ideas? I would love this thing to no longer be a really expensive paperweight. I really can't afford to replace this thing right now
Thanks for your help.

That worked!! I don't know why the stock recovery can fix it when TWRM couldn't. It worked though. Thanks a ton!!

This didn't work for me every time I wipe in TWRP it just never installs the packages, or upon restart it just doesn't mount system. Wipe repair on TWRP doesnt work either

I'm totally with you on wipes and package installs randomly failing on TWRP, but I have no idea why. Sometime in December, I made the switch to Philz CWM, and I haven't looked back since.
At any rate, it is always good practice to odin back to stock, use the stock recovery to do wipes (factory reset and wipe cache), and then odin Philz CWM or any recovery program of your choice.
If you're planning on loading Lollipop, then you might just download the latest from Sammobile, odin the stock and wipe, and then load your custom recovery.
Best of luck,

I have a G900W8, there's no lollipop version for me. What phone FW can I flash and retain phone signals etc.
Captian Double post Double post here.
I'm going to snap my phone in half, it's been over 13 hours of trying to fix this. How does no one else have this problem?
EDIT: YAAAAAAAAAAAAAAAAAAAASSSSS I FINALLY GOT IT TO WORK > I HAVE NO CLUE HOW <
Hello!
First of all, the diagnostic in the title was given by a guy on reddit so ignore it if you want.
My Nexus 7 started freezing and crashing a few weeks ago. Last week I decided to change the rom from a CM 11 m8 to cm 11 m12.
While writing, after sending the system.img, it stopped at writing the system. Decided to try again but first I loaded TWRP and wanted to wipe everything just to be sure.
Apparently, in the console log, there were a ton of errors "cant mount /data", "cant mount /cache".
Looked up some solutions and managed to reformat using a make_ext4fs command. The /data errors were gone but the /cache is still there.
Tried reinstalling a rom again and it still failed. Also I tried to install a rom via the adb sideload. I manged to get a CM 11 running but the freezing was still there.
Whenever I try to install a stock rom, it stops at writing system and it says FileWriteError or something like that.
The tablet has been put to sleep for a week now and today when I opened it in TWRP, the /cache error was still there.
If anyone is interested in the reason it froze, I managed to boot into safe mode and there were a lot of NPEs thrown by Keyguard Manager or similar to that.
Please help me!
Sprint LS980 in an odd state after trying to flash CyanogenMod 12.1
Ok... so I got two of these Sprint LG G2's. I was able to successfully flash the first one with a minimum amount of problems considering I was just learning how to do it.
This second one is a problem though. Here's what I did:
I tried to root but it could not due to the version of the Sprint firmware on the phone. I did the TOT stock flash to get it back to stock. That worked fine.
Then I was able to root it via ioroot. Once rooted, I installed FreeGee and tried to install TWRP, that didn't seem to work, so I installed CWM Recovery. I did option two on this thread to try to get the loki stuff installed using openrecovery-twrp-2.6.3.4-ls980. That "installed" and I was able to boot into it. I installed cm-12.1-20151125-NIGHTLY-ls980 (same one I used on the other phone). That would not install via CWM and gave an error about not being able to lokify (or something like that).
So I said, OK, I must have done something wrong, so I tried to redo stock flash again. That acts like everything works fine LGFlash does it's thing (using LS980ZVA_01.TOT), but the phone boots up and does not seem to finish the install process. The LG logo comes up and not the Sprint screen that I would expect. I can do this over and over again and the results are the same whether I let it sit for an hour or 10 minutes after flashing. So now, the phone boots, but I can't do anything with the touch screen, and will then go into a reboot loop (getting into the OS but rebooting shortly after). I CAN get into CWM where I can wipe data/factory reset and wipe cache partition. After I do that, the phone will boot and will let me interact with it, but after a short time (a few minutes I think), it will reboot again and be in the same state it was before I went into CWM. I tried to do a factory reset in settings. It would say that two reboots would occur, but then nothing happens.
I'm at a bit of a loss as to where to go from here. I don't think that it's an unrecoverable brick, but heck if I know how to fix it.
In between reboots, ADB does see the device in ADB Devices, but shows that it's offline, so I can push an APK to it.
Here are the options that I get in recovery mode:
Reboot System Now
Apply Update From External SD Card
Apply Update From Cache
Apply Update from ADB
Wipe data/factory reset
Wipe cache partition
Any assistance is greatly appreciated!
Ok.. well.. I downloaded and flashed ZVE and it seems to have greatly stabilized the phone. However, it seems that I have lost the ability to do download mode and recovery mode. I can still get into the device through ADB, but ioroot no longer is able to root the device, so I can't install any recovery. There is a system update available to install, but didn't want to do that unless I'm good an stuck in this mode.
I also don't seem to be able to enable the cellular service. I don't know if the update it wants to install would fix that or not.
Edit: I can still do ADB reboot recovery and get into recovery mode with these options:
Apply Update From External SD Card
Apply Update From Cache
Apply Update from ADB
Wipe data/factory reset
Wipe cache partition
Edit2: I was able to root with Stump. FreeGee won't run on ZVE, so not sure what to do from here. The phone does not work at all. None of the phone info is listed in About Phone. No IMEI or anything.
Edit3: I have been able to get TWRP installed and can boot into it. I have also verified that I can get into download mode now. I'm very concerned about my EFS info though. I did back it up, but not to the PC, so effectively I have no EFS backup and no way to recover the IMEI information. Not cool...
Hi I have a SM-N910F model which is proving extremely difficult to flash. I firstly flashed the latest Marshmallow UK BTU firmware on it which resulted in a boot loop. I cleared cache partition and wiped data/factory reset in the stock recovery (and TWRM recovery) but this did not fix the problem. So I flashed the phone again and this time it was stuck in a boot loop with the text "recovering booting..." at the top left. Tried the same as before and still didnt fix it.
So I then tried a different stock rom - Lollipop UK BTU firmware. This gave me the exact same problems as before. However on a few occasions, I also got an error on the recovery screen saying cache could not be mounted. I cleared the cache partition, tried reformatting cache using TWRM but none of this worked. Eventually I reflashed and it went away but the boot loop doesnt go.
Lastly I tried an even older firmware - Kitkat UK BTU firmware. This again gave me a boot loop problem. It also kept displaying the cannot mount cache error as well. I tried using PIT file to repartition the device and eventually the error went but the device would still be on boot loop. However on two occasions the phone did go past the Samsung logo and show the first setup screen (where you select initial settings like Wifi etc). After like 10-15 seconds it would just switch off and then go back into boot loop. I havent managed to get to the first setup screen again.
I have tried flashing with various different Odin versions but still no luck.
I feel like I have exhausted my options and not sure what to do. Do you think I should try a custom rom? If so, for the sake of getting it to start, which is a good lightweight rom?
Does anyone know what I can do to make these infinite boot loops and/or "cannot mount cache" error go away?
Anyone? I could really do with some help..
A little background first, I have had my galaxy (sm-g975F exynos) rooted for some time now with magisk. I wanted to update the firmware, reroot and install TWRP in the process. Took me a few hours and only one mistake but at the end I was successful. This was 2 days ago and Ive been working on customizing ever since.
Now onto the problem, I noticed the camera app didn't work any more when I boot into magisk mode. When I boot in standard mode the camera works fine. I tried force quitting, rebooting, reverting to original settings, etc... and no change. I started reinstalling system apps I removed with debloat thinking I may have removed a system app that had an effect but again no change. I read somewhere that clearing/wiping cache may help so I booted into TWRP, went into advanced wipe and only wiped "cache". Now when I reboot into standard mode the phone works fine, but if I boot into magisk mode I cant get past the lock screen. Basically magisk mode boots fine but when I enter my pin it just goes back to lock screen. So I rebooted into standard mode and made it so there was no lock screen(no pin, no fingerprints, etc...) then I tried rebooting in magisk mode to see if this will get me past the lock screen and now it just bootloops in magisk mode only.
So my first problem is getting my phone back into magisk mode, my second problem is the camera. is there a safe way to reflash with TWRP or am I going to have to redo the whole process with odin?
Thank you in advance for any help, I have searched online but haven't found anyone that has had issues wiping cache with TWRP
update, tried downloading magisk zip from magisk manager, rebooted into TWRP and tried installing the zip, no change. wiped dalvik cache for kicks, no change.
update #2, also tried uninstalling or disabling root privilege apps such as novalauncher, liveboot and buttonmapper but I was only able to do this in non-magisk mode, again no change.
Update #... what # am I on?
So I started fresh, reinstalled stock firmware, reinstalled magisk and reinstalled TWRP. Phone is working fine except for the fact the camera doesnt work in magisk mode. I am now 100% positive this is due to magisk or TWRP. I will try and install another camera app to see if it works, but would still like to figure out how to get samsungs camera app to work in magisk mode.
So I decided to enter into safe mode which ultimately broke my magisk install. Same scenario as before, I can boot into non-magisk mode now but if I try and boot into magisk mode I cant get past lock screen. However while in safe mode and now non-magisk mode, the camera actually does work. So as it stands I can either have my phone rooted and not be able to use the camera or not have it rooted and be able to use the camera. If anyone has any suggested work arounds, please feel free to chime in. In the mean time I will start over again.
another update.
I reflashed stock firmware along with magisk. I now have root as well as a working camera, and yes the camera works in magisk mode and non-magisk mode. I am now looking to blame TWRP or multidisabler in breaking the camera. I know that having TWRP on a galaxy S10+ is fairly new to the market but I am surprised that I cannot find a single other report of someone elses camera not working after installing TWRP. I feel like I should keep trying things but I also have reflashed firmware, magisk, TWRP 3 times in the past 5 days and I just want a working phone with root. The only other ideas I had was to either give the camera root access or make the camera a system app. I dont see why I would/should need to do that though.
Moderator can you please change the title of this thread to "Camera not working after installing TWRP" please and thank you if it is possible.
