HTC One M7 can't perform factory reset

Someone from my family gave me a htc one m7 phone that shows: TO START ANDROID, ENTER YOUR PASSWORD after Power on. I get 30 attempts but after the first one I get: Decryption unsuccessful, The password you entered is correct, but unfortunately your data is corrupt.(I don't know the right password I just typed something)To resume using your phone you need to perform a factory reset.
Then I reset the phone and I get this:
E:missing bitmap oem_unlock_bg(Code -1)
E:missing bitmap oem_unlock_bg_yes(Code -1)
E:missing bitmap oem_unlock_bg_no(Code -1)
E:missing bitmap icon_ruu(Code -1)
Backup necessary files in data partition
E:failed to mount /data (Invalid argument).. try emmc mount
Formatting /cache…
Data wipe failed.
I also did a bootloader factory reset and got the same result.
I don't know anything about the phone, I just want to erase all and return it to the original state.
If someone could tell me what the error means and what should I do, would be appreciated.
 
I don't suppose the person who gave it to you could explain how they got it in that state? Had they tried to unlock and modify it, set S-Off (as mentioned above)? Knowing what they've done might help with fixing it.

But I think the real question is whether you can get into fastboot mode from the bootloader. Because if you can then it should hopefully be possible to reflash the phone. But we'll need some information about it to locate the right software, e.g. what country/carrier it was originally sold to and what software version it's currently running. If you can install a program called "fastboot" on a computer (you should be able to download from HTCdev.com), connect the phone to the computer via USB, put it in fastboot mode then on the computer run the command "fastboot getvar all" and post the results (without the IMEI and serial number) then that should contain everything we could need, but otherwise any info about the phone's origina and its current software will help us guess right.

I was able to enter fastboot mode in the bootloader and I was ofered the following options:
BOOTLOADER
REBOOT
REBOOT BOOTLOADER
POWER DOWN.
I guess one of these options will reflash the phone, I just don't know which one or how. Maybe a link would help if you know one.
