Unable to mount /system: Galaxy Tab 4 SM-T230NU 7
I'm on TWRP 3.2.3-0. I've rooted the device and am trying to mount the system under the Mount menu.
It is not mounting. So when I go to install a custom rom I keep on getting "failed to mount /system" error....
I don't have anything backed up so I can't restore anything.
Help please...
Yeah i dont why its doing that now. I learned a fix, click on advanced wipe, select data, select change system file, select fat, wait til it changes and change it back to ext4. You should be able to wipe the system now. If it doesnt work the first time, reboot to twrp and itll work

Please help D: Recovery's cant mount /data and internal card, CWM - "Error mounting /data!", TWRP - "e:unable to mount /data", so any CM fw go into infinite loading. Any suggestions?
Hi
I was able to install Link2SD Plus version on my rooted tablet but I'm seeing following message after reboot.
Notification: Mount warning
Since thee 2nd partition is not mounted during boot time it has been mounted after the system finishes.
Therefore your linked apps are not visible to the system at the moment.
To make them available again, please try 'Recreate mount scripts' or 'Quick reboot'
1. I tried 'Recreate option' but I have this warning always.
2. When I tried quick reboot I had screen flicker and still got the warning,
I see the ext4 partition mounted already
#df
/data/sdext2 18.2G 4.0K 18.2G 18.2G 2048
What should I do?
I also uploaded the link2sd log files found in /data/ directory
Thank you.

All,
I have a SM-G35FD which is in a bad state. My phone started boot looping one morning after it was fine the night prior (3 days ago now) and I believe an auto-update may be the root cause. I am trying to find any way to access the internal memory to recover data, however I am not able to mount /data or /sdcard. I have not done much with my phone besides adding root, no CFWs ever, and no custom recoveries (prior to today). Also, I lock my phone with my thumbprint. I did not go through any encryption setup on my device.
Details about the initial problem:
It started boot looping several times and at some point it shows a black screen with red text. after letting the battery drain (because I could not force reboot) i was able to get into stock recovery and wipe the cache and reboot; this led to occasionally getting to the security screen which would freeze 1-2 seconds after logging in.
Things I have tried (19mar2017)
got into stock recovery, wiped cache, rebooted. Freezes at security login screen
Installed TWRP to get more functionatity. Was able to install TWRP
used TWRP to try to mount Data, but it will not mount (only System, Cache, EFS, and USB OTG will mount)
used TWRP to wipe Dalvik and Cache only. Errors show "cannot mount /data"
used TWRP to install CWF, freezes during extraction (4-5%)
can use ADB to run shell
UPDATE 20mar2017: Ran "Wipe -> Advanced Wipe -> *Select System Partition -> Repair or Change File System" on /system. I think this was a bad move as now I can access the /sdcard folder and its missing all data. I didn't think it would matter since the options under Wipe show "System" and "Internal Storage" separately.
Perhaps data does not mount because it needs my thumbprint? Is there anything I can try to backup the internal user memory partition and my fingerprint signatures? any way to access the user data?
Thanks to all for their time!
I found a video ( https://www.youtube.com/watch?v=VJRKuQf0puE ) which suggest that I can use TWRP to "change the filesystem" for the /System (and other) mounts in order to fix the /data mount. This can be accessed using Recovery(TWRP) -> Wipe -> Advanced Wipe -> *Select System Partition -> Repair or Change File System -> Change File System -> Options { EXT2, EXT3, EXT4, FAT, exFAT, F2FS }. Since my goal is to recover the "User Data" partition, I would not perform this on "Internal Memory" but would on the other partitions. Hopefully this would allow me to reinstall the Stock FW and allow me to login to the Internal Memory to access my files.
Does anyone know if using "Repair or Change File System" will impact the Internal Storage?
Try to reinstall the Stock Firmware Through Odin, I had this problem also when I used to own a J5... All I did was just Reinstall the stock firmware... if you want to find the stock firmware.. just go to sammobile.com
So, my mom's P8 lite was running low so i offered to "make it faster" I succeeded in unlocking the bootloader and flashing SuperSU at first. Now the next issue at hand was thus a custom rom. I've settled on https://forum.xda-developers.com/p8lite/development/rom-t3649258
In accordance with instructions i flashed the b895. Everything went fine until the last possible second
twrp "errored" with something like error [] errno. That's it. I rebooted and everything seemed fine. However in about the phone is now listed as hi6210sft and initially did at first too in windows explorer. I enabled developer options and usb debugging and suddenly windows was seeing it as an ALE-L21 again about phone still lists ALE-B895.
I can copy files over to internal storage "fine" but that's where everything stops. When i reboot to twrp the rom recommended one https://forum.xda-developers.com/p8lite/orig-development/twrp-t3583180 it fails to mount /data
When i try the twrp sideload way i get this (Red: red line of text, wht: white line of text)
Red: Failed to mount '/data' (invalid argument)
Red: Unable to recreate /data/media folder
Wht: ..Done
Red: Unable to mount /storage
Red: Failed to mount '/data' (invalid argument)
Wht: Full SELinux support is present.
Red: Unable to mount /data/media/TWRP/.twrps
When i go to mount i cant mount data, when i go to wipe > advanded internal storage is shown as 0 size. When i go to Wipe > advanced > Change file system to FAT that works and storage sizes are now reported (in MB), but i still can't see anything on the internal storage. Can't install anything as that damn basic EMUI doesn't even have a file manager.
Right now i'm at a catch 22 as with Huawei removing all downloads, i can't even download the stock firmware
This phone is an "old" P8 Lite, ALE-L21 european (belgian) model.
Right now the status is as follows
* fastboot & adb work
* phone boots
* twrp installed but can't mount any storage, thus can't do a damn thing
Any assistance is welcome.
I'm used to working with Nexus devices so i'm unused to all these problems

Make Full Reset All data will be lost but data partition will be mounted
Format data in twrp
Ah that seems to have worked. Apparantly wipe data is different from format. Learned something new. after formatting i was able to adb push the custom rom and install via twrp. Files place on internal storage are now properly seen by TWRP. Device is up and running. Many thanks
Never too old to learn something new
Oh anyone know where i can grab the latest stock firmware for the ALE-L21 Eu model "just in case"?

I had this same issue (just got my PH1). I had to reboot to bootloader and get back into recovery. From there, I was able to mount /system once I got back in. Note that I did take a pitstop in slot A recovery (I have TWRP in slot B) and mounted system there too. Hopefully this helps.
EDIT: Fyi the key is going into recovery for partition A and mounting system there.
