[Q] Failed to mount /data (Invalid Argument) Error

While trying to flash back to stock from a custom ROM, I made it to the Samsung splash logo, and got stuck there. Went into recovery and saw the following:
E:failed to mount /data (Invalid Argument)
can't mount '/data' (invalid argument)
[The Applied CSC code is ATT and successfully applied multi-CSC stuff appear in Manual Mode]
E:failed to mount /data (Invalid Argument)
can't mount '/data' (invalid argument)
E:failed to mount /data (Invalid Argument)
Now what must I do to get everything back to the normal? Please help!

Can someone really help me with this scenario? I seriously need help!

Try flashing your stock firmware via Odin. What build are you currently on?

Unable to mount storage in TWRP, unable to open '' to wipe crypto key

Hello everybody,
I'm facing an issue with my phone. I was running Fulmics Rom 6.1 on my LG G3 for a few days, when, this morning, I woke up to find my device caught in a bootloop. I had a recent TWRP backup, so I tried to restore it, but it failed with the error : "Unable to wipe System".
I tried to wipe everything but my SD Card and got :
Code:
Failed to mount '/data' (Invalid argument)
Failed to wipe dalvik
Updating partition details...
Failed to mount '/system' (Invalid argument)
Failed to mount '/data' (Invalid argument)
Failed to mount '/cache' (Invalid argument)
I tried to use "Format Data" in TWRP Wipe Section, but got :
Code:
[B]Unable to open '' to wipe crypto key[/B]
Unable to wipe Data.
[B]Unable to format to remove encryption.[/B]
Updating partition details...
Failed to mount '/system' (Invalid argument)
Failed to mount '/data' (Invalid argument)
Failed to mount '/cache' (Invalid argument)
Flashing the Rom again fails as well as it stays stuck at this step :
Code:
Install new system
Extract:/tmp/unpackbootimg
I'm using TWRP 3.0.0-0.
Any idea about what I could do next ?
Thanks a lot.

E: failed to mount /cache (invalid argument)
E: Unable to mount /cache! give up!

I know it's too late! but I have the same problem.
Did you fix it?

Me too, any news on the topic?

I don't have Droidboot any more but it still alive because I can plug it as cloverview. Now I need the debrick files. I can't find all the files in the firmware (zip/raw)!

Update to TRWP 3.4.0-0 failed - factory reset?

TWRP won't start after updating from 3.3.. to 3.4.0-0 using fastboot. Output includes "Failed to mount '/data'" - see following post.
I guess because I accidentally ran fastboot unlock although it was already unlocked. (The TWRP website fastboot update procedure starts right back with installing the tools and I jumped in at the wrong place)
Tried installing previous TWRP version but no dice.
Any ideas?
I did a TWRP backup before all this. Not exactly sure where it's located but would like to recover it if possible. Will a factory reset likely overwrite it?
