Hi, bought this tablet a couple of weeks ago and successfully rooted device with no problems(I think at least). I got a notification to update Magisk and I decide to boot in recovery to do so. But not only is the SD card not showing in TWRP but the internal system files are not present either. A few folders do show up but they all are empty.

Hello,
Will try to explain the situation to my best possible knowledge :
1. Was running Crash ROM 4.4.2 on Galaxy S4 i9500 , have got all the required apps installed and configured the way I wanted.
2. Running the stock kernel which comes with the Crash ROM installation.
3. Running Phillz touch recovery 6.3.xx
4. Have external micro sd card (16GB UHC SanDisk) . Crated 1st primary partition as FAT32 and 2nd primary as Ext3 for moving apps.
5. Did install Link2SD and correctly moved all apps linked to the 2nd external SD card partition.
6. Was able to connect a USB flash drive via female USB connector (host mode) and take titanium backup of all apps.
7. Everything mounted correctly and automatically, with correct permissions to read/write without me worrying or fixing any setting or changing anything.
Since I had everything in order, I thought of making a nandroid backup via Phillz recovery . The problem when I tried taking a nandroid baclup which presents custom backup option to either "/sdcard" or "/storage/sdcard1 (which i assume refers to external microSD card".
I tried taking a backup at both locations and was informed that I am short of space , the backup needed 4+GB whereas I had 2+GB on internal SD and 3+ GB on external microSD available.
So i thought to reboot and try making some space anywhere, thats when the nightmare started.
After reboot, now there was
1. A message for low space remaining
2. Google play store continually crashing and giving a "stopped" message.
I fixed the error no. 2 temporarily by uninstalling google play store (updates, cache and then the app itself).
However error no.1 persists, now when try running any app to see what and how much space is left in the internal and external SD cards, it seems that the internal SD card is not mounted somehow.
I have tried runnning ES explorer and it says no SD card found. Even though I can browse to the root partition. Then I tried Link2SD (which has an option of seeing storage info nicely) and I can that the bar for SD card is blank and all other places or mount points are mounted.
Even the apps residing on my external microSD 2nd partition are working fine, however I noticed that earlier the external microSD card, when seen from inside a booted and loaded ROM was mounted at the location " /storage/extSDcard , but now it is mounted at "/mnt/media_rw/extSDcard"
But my internal SD card is vanished, I cannot find any contents of the "internal SD" in any of the locations at /storage , /storage/emulated/legacy, /storage/emulated/0, /sdcard, /mnt/sdcard, /mnt/obb and possibly any other location I can think of.
I believe the mount points and logical links are different as seen by the phillz recovery (as there is no /storage/sdcard1 when seen from Es explorer) , and as seen when the ROM is fully booted and loaded, so when trying to take a nandroid backup via Phillz recovery, it might have messed up with the mount points and/or permissions.
I hate doing a complete re-flash of the ROM again and spending hours to get all the apps customized my desired way, with all widget settings.
I am not an expert or pro at android, hence I request your help to sort out the issue, and maybe send or guide me the default way the S4 handles mount points, so I can get back the SD card and also guide me how to make a the nandroid backup to avoid this fiasco again.
Thanks for reading.
I just upgraded to the new AICP Nougat, no issues, except for a small nuisance where it will read the SD card i have formatted as internal storage as blank in the OS, however when I transfered files through TWRP (cuz PC to OS is super slow) it shows my files there. I've done the same method in the same directory before with no troubles (PC to external_sdcard/ via usb). Rebooted into recovery after finding out this issue, and it still shows the same files in external_sdcard. What did I do wrong?
Hi all I need a little help, I completed everything above without much problem, but when I flashed the newest twrp recovery, I did a backup first thing then when it was completed every file is in my internal storage and it's not showing up an sd card when I have a 16gb installed and I'm sure twrp is the step that caused this. I am still on OF1 rom. Thanks for any help!
The unlocking step overwrites the external (removable) SD card with a copy of the first 256 MB of your flash memory chip before it modifies the "aboot" partition.
A side effect of this is that the card won't mount correctly any longer without re-formatting it.
To be completely safe (you'll probably never need it), do a "raw copy" of the first 256 MB of the external SD card device to save the "debrick image", e.g. (as root)
Code:
dd bs=131072 count=2048 if=/dev/block/mmcblk1 of=/sdcard/SMN900V_debrick.img
This might take 20-30 seconds or so as you are reading and writing 256 MB of data.
Then, reformat the external SD card.
Separately, TWRP has a menu that allows you to choose between the output location for backups - either the internal memory, the external memory (SD Card), or - if you have an OTG cable, on an external USB device.
TWRP also has a file explorer if you want to move your saved backups to the external SD card. It's a little clunky, but it works. (You can also do this with a file explorer app with the phone normally booted as well if you prefer).
cheers
maybe you have to install sdfix since phones of the past couple years don't use sdcards, the system updates don't recognize cards

Click to expand...

Nope, you just have to reformat the card and it'll be fine.

Well i think my SD Card is acting strangely since i did the new marshmallow update
When i was still running with 5.1.1 Lollipop i was able to move all apps to sd card with no problems at all,
i did a factory reset to get rid of the root and then updated to marshmallow 6.0.1 and at first i could move apps to sd card normally like i used to do with the lollipop and everything was fine until i restarted the phone, when the phone restarted all apps that were on sd card were greyed out with a small sd card icon bellow each one and when i tap on it it says app not probably installed i knew this was a common problem and leaving the phone for a few minutes would restore it but i left my phone unused for 3 hours and apps remained greyed out so i deleted them and redownloaded them again for play store but this time when i tried to move them it would say not enough space on sd card although there is 6 gbs of free space i thought maybe some leftovers from those apps still remained so i formatted my sd card 2 time once with the android and another time from my laptop ...nothing changed still cant move apps to sd card ...and on plus on that when i connect my phone to my laptop it only reads the internal storage it doesnt show the sd card as if it isnt there
any suggestions?? Any help would be appreciated and sorry for my bad English

This has been effected by the new security feature on Android 6.0.1 firmware so as not to alter app system files. You should also check your SD file system (format) for compatibility. Also if your are running a custom kernel, Android security patch prohibits non-trusted apps from making changes to to execute as system files outside the inbuilt storage
Hello Community,
hope to be right here.
My Sony Xperia X Compact starts only in a bootloop after restart with a completely full internal storage.
The phone had about 400MB free internal storage for a longer time.
Yesterday, because of an empty battery, I restarted the phone and it had left 4KB internal storage.
So I rebooted it again, and since then it is in a bootloop. Sony-Screen, Android-screen, black screen, then it reboots again.
The phone is rooted and twrp is installed.
I tried to get access to the internal storage (to delete some data) via adb, the device is not found, only via fastboot detected.
I also tried to get access via twrp-Explorer. In the file system it shows me the Folders sdcard and sdcard1. sdcard1 shows me the file system of the external sd-card correctly, but the Folder sdcard is empty.
Choosing in twrp (backup) the backup-device, I can see the internal storage with 0MB. For the SD-Card is the physical space of the card listed.
I made a backup of the data-partition with twrp. Trying to open this backup on the computer as a .tar-archive runs into an archiv-error.
At this point, i don't know what to do to extract some data from internal storage and make more free space in the internal storage for boot.
Is it only the software which crashed, or is the internal storage defect?
Is it a completely other error?
Do you have any idea?
Thanks in advance
