ERROR on recovery --> E: failed to mount /data (Invalid argument)

[maidmarian4]

Ok so I don't know if it is related, but for the last 3 weeks, my phone has often decided it is going to be slow OR... it has a mind of its own and without any fingers, water, or other things touching it, will type on its own, select files, attempt to change the wallpaper, etc. No matter how much I mash my fingers on it to "listen," it just keeps at it!

So, today I thought I would just do a soft reset via recovery and wiping the cache partition. I've done it before for the above problem, and thought it doesn't hurt to try again to see if it helps (I am undecided as to if it makes any difference). I did wipe the cache partition, then chose "reboot system now" and it got stuck on the ATT logo screen. I repeated this process 3 times and it doesn't change the result. Every time I reach the recovery screen, the lines below the yellow text "Successfully applied multi-CSC," it says (exactly),

E:failed to mount /data (Invalid argument)
can't mount '/data' (Invalid argument)
E:failed to mount /data (Invalid argument)
E:Can't mount /data/log/recovery_log.txt

Besides doing a full factory reset (which would hopefully solve the problem), what can I do to fix my phone?

TIA!!!

Since /data is where your information is stored there's no downside to performing a Factory Reset in Recovery mode. You might as well do that and see if the phone boots properly - if it gives you some other errors it may be time to reload the firmware.

If there's a Best Buy nearby you could take it in and they should be able to wipe/reload the whole thing.

Hello and welcome to the forums!

Buying a new phone would be a pretty drastic solution. I'd suggest booting into Recovery mode and performing a Factory Reset to see if that corrects the error.

Hello,
I have the same problem - wiped cache partition and ever since my phone is stuck in Galaxy opening pic (whatever it's called - showing the phone model).
I tried to reload my firmware using Odin (as I did several times before) but the problem hasn't been solved.
I can access recovery but not the rom, and if I try to do factory reset I still get the same result - failure to mount /data.
I suggestion or explanation to this problem?
Thanks

failure to mount /data.

No explanation really - wiping the /cache partition shouldn't touch the /data partition.

Unfortunately, when you use Odin to load firmware it usually doesn't touch the /data partition (assuming that you may want to keep your data intact). You could try using the Kies software to reload the firmware, or find a ROM that specifically wipes /data. I imagine that you could even use ADB to wipe/format the /data partition but I can't tell you the commands offhand.

I had the same problem with a Samsung Note II with custom bootloader. Using Philz y delete all partition with the option clean partition for new rom, then loaded latest samsung rom and format /data with the original recovery software several times. Finally I was able to recovery my cell and saves some money

Hello, have you been able to fix your phone?
I got the same error when I did a factory reset and then it got stuck on the welcome logo. I got to the system recovery screen, I did a wipe cache partition, then a factory reset and tried to reboot but it still gets stuck on the samsung logo.
How do you get past that? I have backed up all the info i need so i'm not worried about losing data.
I don't know anything about softwares or what odin or kies are, so a step by step solution would be much appreciated!

Thank you

This it what i do: Using mfastboot I erase all the partitions, except boot and recovery:

mfastboot erase cache
mfastboot erase system
mfastboot erase userdata

After that I enter to recovery and everything works normal.
