Couldn't mount /sdcard - Android Q&A, Help & Troubleshooting

I need to flash a ROM on my device to root my VFD600, but can't flash it due to this message always showing up. How to fix it?

E:try to mount "/dev/block/mmcblk1p1" partition at "/sdcard" with exFAT filesystem
E:vfat mount failed, try to mount with fuse exfat
E:/sbin/mount.exfat failed with status 1
E:fangjun failed to mount /sdcard (No such file or directory)
-- Couldn't mount /sdcard.
Installation aborted.
Neither applying from ADB sideload or Fastboot commands other than "fastboot devices" work for me, so I can't even unlock the bootloader.

[Q] /emmc/ wont mount in CWM after encryption

CM10 recent install from CM9, which was Encrypted for work email.
Read that you can just format the partition and it will install new roms fine.
Within CM10 I can see /ExtSDCard/ and but /SDCard/ aka /emmc/ in CWM wont mount.
Going further down into CWM, emmc wont mount so it looks like it has installed the rom fine as it boots without a physical SD Card inserted? When trying to mount /emmc/ the log shows the following error "Failed to mount /dev/block.mmcblk0p11" which I assume is related.
I would like to mount and format the previously encrypted internal storage, so It could be used as /sdcard/ in CM10 so apps like Camera would work.
Thanks
Edit: Fixed English
Edit: Ok so I have worked out its /dev/block/mmcblk0p11 - cant format it ext4 then mount it using "mount -t ext4 /dev/block/mmcblk0p11 /emmc" but all the 'scheduled' tasks still think its vfat, so as a work around ill just format it as vfat.
This should be easy.... right?
busybox mkfs.vfat /dev/block/mmcblk0p11
Error:
mkfs.vfat: lseek: Value too large for defined data type
Ugh. Help me format this as vfat please
Fixed!:
Had to push a new version of busybox, which allowed vfat over 1gb.
Thanks me!

Lenovo A560 stuck at boot

A friend just gave me a Lenovo A560 which won't boot at all. I can enter recovery mode, tried reseting with no use but it seems to have problems with mounting block devices.
Code:
E:failed to mount block devices /dev/block/mmcblk1p1
E:remount block devices /dev/block/mmcblk1
E:failed to mount /sdcard (No such file or directory)
E:failed to mount block devices /dev/block/mmcblk1
E:remount block devices /dev/block/mmcblk1
E:failed to mount /sdcard (No such file or directory)
E:volume for path [/cache]
Any help would be apreciated, I am willing to try any experiments to sort it out.

Hi. I just managed to fixed problem wont boot yesterday on my A560. Unfortunately when I running recovery mode and trying to flash other ROM, it shows exactly what you write above. However below is what I did to make my phone pass Lenovo logo:
1. Download official rom in needrom website.
2. Extract the file.
3. Put the extracted file(system.img,recovery.img,cache.img,boot.img,userdata.img) inside folder you installed ADB. For me is C:\android
4. Remove battery from your phone for 5 seconds, put is inside back, hold both volume buttons along with plugging USB cable. Your phone will only show Lenovo logo(fastboot mode)
5. Run cmd.exe, type cd C:\android and press enter.
6. Copy below code:
fastboot erase system
fastboot erase recovery
fastboot erase cache
fastboot erase boot
fastboot erase userdata
paste it then press enter.
6.After it finished, copy:
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash cache cache.img
fastboot flash boot boot.img
fastboot flash vendor userdata.img
and press enter.
7. Copy:
fastboot reboot
and press enter.
8. This should reboot your phone back and enter the new flash official ROM.
Forgive for my bad English and please let me know if these works for you
Thank you very much for dedicating your time to help me. I really apreciate your help. I succeded earlier in installing the custom rom from the website you provided above and it works well. Cheers

[Help me!] Internal sd can't mount, unable to flash new rom via adb sideload

Couple months ago, I tried to flash Android 6.0 on my S2 i9100 but it only recognized the first partition (2gb ) but the rest 14gb no. [ Sure, I did wipe cache partition, dalvik cache, data ]
So, I did some format with adb shell ( I deleted FactoryFS, Data, UMS partitions and change the format type to Fat32) and copied to internal storage. When I install it ( it takes like 3-5 minutes) and get this error
|Warning: No file_contextsdetected filesysstem ext4 for /dev/block/mmcblk0p9
| mount: failed to mount /dev/block/mmcblk0p9 at /system: Device or resource busy
| detected filesystem ext4 for /dev/block/mmcblk0p9 It stuck here for a while
ApplyParsedPerms: lsetfilecon of /system/lost+found to ubject_r: system_file: s0 failed: Operation on not supported on transport endpoint
set_metadata_recursive: some changes failed
E: Error in /emmc/cm12.... (status 7)
Installation aborted
press any key to continue.
After that, I tried again with Odin, I used Stock PIT and 12gb PIT ver to install Rom, still get the error above. Even when I use Odin to flash new Rom, Odin get stopped working.
[ I have tried many versions of CWM, Philz, TWRP,... but still Can't mount /sdcard ]
So how can I fix this problem?
Thanks for reading and helping me. Also sorry for my bad English.

how to mount modem partition as r/w?

my modem partition shows as protected in flashfire.im guessing its read only? how would i mount it as r/w in adb.I have root and busybox. the mmc block is /dev/block/mmcblk0p1
adb shell
su
# # mount -o remount,rw /dev/block/mmcblk0p1?
i've tried that command, i dont know if its correct it give no errors but its still read only
Sorry
But have you found a way to mount modem partition
What is the command for it?
I accidentally erased all by flash tool
And now SIM not working
Even after flashing stock rom
I have Lenovo phab plus
And I could only install twrp recovery and root
But the recovery can't mount
It returns to default again after restart

You need insecure ADB to do that, which requires ROM modification. Or do it in TWRP, which is insecure by default.
Insecure ADB is enabled by "adb root" on your PC.
Also, when remounting, you should specify the mount point - not the block device. E.g. /modem. You can check "mount" command to find the existing mount point.
Boot into TWRP and run:
adb shell mount -o rw,remount /modem or /firmware
But you may get errors as this partition is probably write-protected. You'd need to modify your fstab to make it always read-writeable
The best way to modify is to dump the partition and modify within Linux then reflash to the device
