Re-flash the ROM or restore that is if you made any backups, you don't have to wipe your data this will solve the problem.

[Q] How to recover from s storage mounting error

Ok I tried to flash "Mind Blown" kernel this yesterday morning and I haven't been able to mount internal or external storage ever since. I was running Axura 2.2.8.8 with the lag fix disabled and flashed Eugene's kernel and upon booting was stuck in a boot loop. I decided to try and run recovery mode but noticed that my sd card read no data. Upon an odin back to stock I realized that I could no longer mount internal nor external storgae and got the error in recovery mode I
E:Can't mount /dev/block/mmcblk0p1 (or /dev/block/mmcblk0)
(Invalid argument)
E:Can't mount SDCARD:
Once my vibrant boots it says internal storage damaged and external says missing or invalid mount point. I flashed kernels, roms and virtually everything I possibly know how to do, and now I need the help of an absolute wiz. Guys i really need your help with this one, I'm totally lost.

Cannot mount SD!

So I flashed a new ROM today, Pier's latest AOKP ROM, and I think the latest CWM6 is causing some problems with the mounting and stuff..
CWM can't read my SDCard and mounting SDCard or USB Storage just fails..
It gives Error Mounting /sdcard when i try to mount SDCard, and for USB Storage, it just gives Unable to write to ums lunfile (No such file or directory)
Can't flash, backup (Nandroid) or do anything to my phone :/
Would appreciate if anyone could help?
Is it possible if I flash an old CWM Recovery via Odin?
Thanks!
How hard is it to wipe?
Sent from my GT-I9100 using xda app-developers app
How hard is it to refrain from posting in this thread, if you're not keen to help?
try cleaning the cache of the apps that are not working. some of the data saved by the app from the previous rom maybe causing problems.
Sorry, updated op, just found the real problem!

[Q] Help wiping data android_secure error

Hi guys
I'm on cm 10.1 20130813 nightly for Galaxy s2
the folder android_secure can't be deleted
even on PC it will be deleted but once I unplug the cable opening root explorer it will show that the folder is there
when I wipe data it shows up this
-- Wiping data...
Formatting /data...
Formatting .cache...
Formatting /sd-ext...
Formatting /sdcard/.android_secure...
Error mounting /sdcard/.android_secure!
Skipping format...
so I cant format internal storage from recovery or mobile
in PC I can format it but the folder .android_secure will remain
Any solutions ???
should I have to install kernel or cwm or installing official firmware with odin
what to do ?
thank you
Leave that folder alone. It will always be there.

Won't solve anything if you format to different sd card format.

I9300 - Unable to find partition size for /boot

Hi Guys,
I'm pretty new here and hoping you can all help me with unbricking my phone.
So I have a Samsung S3 I9300, with CM 13.0 installed, I am using CW recovery v2.7.0.0
I've installed many custom ROMS to this device over the past few years without a problem, each time formatting and wiping Dalvik cache etc..
Today my phone randomly rebooted and a message came up that my phone failed to encrypt and it wiped all my data and that I had to reboot into recovery to perform a factory reset.
A bit random I thought.. So I rebooted into recovery and did a "reset to default" in CW.. this was successful, however I noticed some issues on the terminal screen...
Code:
E: Unable to find partition size for /boot
E: Unable to find partition size for /recovery
E: Primary block device /dev/block/mmcblk0p12 for mount point is not present!
E: Unable to mount internal storage
E: Unable to mount /data/media during GUI startup
E: Unable to mount /cache
Full SELinux support is present
E: Unable to mount /cache
E: Unable to mount /cache
E: Unable to mount /data/media/TWRP/.twrps when trying to read settings file
E: Unable to mount /data
Updating Partition details...
E: Unable to mount /efs
E: Unable to mount /data
E: Unable to mount /data
E: Unable to mount /cache
E: Unable to mount /system
E: Unable to mount /data
E: Unable to mount /preload
E: Unable to mount internal storage
I've tried to format but it shows failed.
I cannot install another ROM as both the internal memory and SD card both show 0MB
I've plugged the SD card into my computer and there are still files on the card.
I've had a look online and found that typing in a command into the terminal should fix it, however nothing happens..
I get an error that mmcblk0p12 does not exist.
Code:
mke2fs /dev/block/mmcblk0p12
Any help would be great! Although i'm pretty sure it's bricked
Cheers Guys!

Did you have any success with this, Chris?
This sounds like what happened to my I9300 on CM12.1. It just froze and only rebooted to Samsung logo and stayed there.
When in TWRP recovery, there's just no access to internal memory or SD card.
The terminal mentions a lot of "E: unable to mount /data", /cache, /system, storage, etc
Most TWRP options fail to do anything, because of not being able to access partitions.
No factory reset, no wipes, no installing img's. When rebooting to system, it warns about no OS being installed.
Downloading a stock firmware now to see if it flashes via ODIN, but I don't have high hopes for it.
Does anybody know what would cause this? Or is it just bricked now?

Ah well, mine seems dead too. The recovery doesn't work anymore, only download mode, but ODIN can't get anything on it...
I think the main storage just died.

Damn, I dunno what happened.. My CM was a nightly though, SO I can only assume it was unstable.
Just bizarre how my phone rebooted and gave the message that it was unable to encrypt the device and needed to be factory reset.

I was running a quite stable CM12.1 version for a couple of months now. Only had two reboots all this time.

I had a few reboots when it was working, then it just suddenly bricked my phone
Sounds like the eMMC brickbug. You need to get the eMMC replaced. All of you that face the problems.
Well, after four years my S3 was getting very slow. It was bearable with CM, but I decided to say farewell now.
Also, my microphone was busted when I dropped it at some point, so I could only call with a headset anyway.
It's not worth replacing I think, time to move on
The same happened to my Beelink GT1 S912 9377 TV-box (after failed OTA update). Will check eMMC brickbug (from TWRP) ...

internal storage failed to mount Oneplus One

I have an old Oneplus one that I would like to get working to recover some data. The phone is stuck in a bootloop. This happened out of nowhere one day while charging. I was running CM 11. I can still access twrp(version 3.0.2-0) and i can enter fastboot. The various partitions are as follows Boot(16MB), System(733MB), Data(OMB). The 0 MB in data in odd. Also the storage doesnt mount. Whenever i try to format data it says, "Failed to mount '/data'(invalid argument), unable to recreate /data/media folder, unable to mount storage". If i try to repair or change the file system, it says the same thing. Any help would be appreciated. Thanks.
