Format data and fully wipe

You just erase or deleted files on your internal memory. But no biggie, just flash firmware with Odin (on windows) heimdall (on Linux).

Ignore the cpefs error, it's erroneous and will be fixed.
As long as you can mount data you are good.

[Q]"I:Can't format unknown volume: /external_sd" in CTRecovery

Hi XDA Users,
Before asking help, i would like to say that I'm newbies, i'm little bit lost here, and i don't know if i have the permission to post this question here. Sorry if i make a mistake

I tried to change updater-binary(No change) and I tried to use empty updater-script: this error is not linked at a command line in my script(No change)
The recovery used is Carliv Touch Recovery porting on my device(Wiko Highway)(link: http://forum.xda-developers.com/showthread.php?t=2471479) he works without problems, but i noticed that i have some bad line in my /etc/fstab. I tried to repack a new .img whith good /etc/fstab version but my device was stay on boot image. I have restore my first recovery.img
My question is: CWM try to mount all partition in /etc/fstab at start of updater-script? And if yes, can i disable this function.
I you see something for my recovery problems, i take all tips!
Thanks for you attention,
Antoine

Ignore the key driver message - we all get it.
So you /data partition is not in a recognisable format and cannot be mounted. Please format it in TWRP or from adb use this command when in TWRP (make sure MTP is turned off)
Code:
adb shell
killall -19 recovery
make_ext4fs /dev/block/mmcblk0p8
reboot
or in the bootloader use this:
Code:
fastboot erase userdata

In TWRP, go to wipe -> advanced -> format data. This can take more than an hour, so be patient.

S6 and failed to mount /efs (invalid argument)

Hello guys,
The initial situation is a bootloop on S6 (920F). At stock recovery appears e:failed to mount /efs (invalid argument).
I tried this thread to correct the problem --> http://forum.xda-developers.com/galaxy-s3/general/how-to-fix-efailed-to-mount-efs-invalid-t2858056
So I flashed the stock rom V5.1.1 (DBT) and twrp to have access to adb. Connection via adb is established (adb shell).
But if i sent "mke2fs /dev/block/mmcblk0p3" i become this error: Could not stat /dev/block/mmcblk0p3 --- no such file or directory.
What´s wrong, can someone help.
Thanks in advance
