Hello,
I have a bootloop on my SGS 2 after flashing PhilZ-cwm6-ZSLPQ-OZS-3.99-signed.zip in recovery.
I had installed the MIUIV5 ROM : SGS2-3.8.23-FR-signed.zip on a Siyah kernel but we are supposed to have a new kernel for JB that is why I tried this PhilZ's kernel
the error messages are : E: failed to mount exfat /dev/block/mmcblk1p1 /sdcard
and after tweaking some more, I have a failure to mount sdcard (I had formatted many thing in the hope to clean things up but I am lost now.
Would any one have an idea to help me recover my phone ?

[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.

[Q] Q: Mounting Problems In CWM

Hello,
I just unlocked my rooted prime and flashed the newest CWM via Rom Manager.
Now I can't backup my existing rom. Also I can't install any custom rom.
When I hit backup in CWM, it sais "Can't mount backup path"
When I hit install zip from SD, there is another error "Can't mount /sdcard/
I also tried TWRP Recovery, with no success.
Code:
E:failed to mount /data (Invalid argument)
-- Could not mount: /sdcard.
-- Aborting

Just for info: My device is still running stock rom and is encrypted.
Has anyone a solution for this?
Thank you for your help.
With best regards,
B-Paul
Restore is borked in the latest version of CWM. Push 5.8.2.0 and everything will be OK.
Just tried, still the same error message

You can't mount /sdcard/ (which is a symlink to /data/media/) when device is encrypted, cwm/twrp do not know how to handle this.
edit: Looking at my Nexus, only way to step out of encryption is to use fastboot. It should work like this for the Prime as well.

When I tried to mount sdcard in Recovery mode, it can't mount sdcard. They show this error

Is my card reader chip on my s2 broken?
Go to Settings/Security/
Device Admins and see if there are any possible restrictions else try wiping cache and dalvik cache (just in case) !
oh i just read it again and i saw you posted EXTERNAL sdcard, haha i thought it was internal sdcard
well do what niku~ said. first go in security and see if there's smth and wipe cache/dalvik.
it happened to some people that flashed a theme to the Rom, and after flashing another theme, the bug disappeared...so if u flashed a theme, try it...
if it doesnt work, try reflashing Rom.
if it doesnt work too, i suggest you do a full wipe and flash another Rom.
this is probably a software issue

Error mounting /system in CWM 5

Hi!
I tried to install Android on Samsung Wave GT-S8500. I flashed FOTA and bootloader and got into recovery but since it can't mount /system (same goes for /data and /cache) I can't install any ROM or make any backup.
Is there any way to get those partitions to mount as they should?
wrong kernel. Search Kernel NAND and copy it on SD. You have Kernel SD and u need ro format SD for install any rom

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?

Hey there,
Nope the cmd I found on-line I found (above) didn't work.

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) ...
