[HELP]Moto E TWRP error in filesystem and Boot-loop.

Im using Moto E 1st generation, Bootloader unlocked with TWRP custom recovery. I was using custom rom Marshmallow by Temasek and I thought to change the rom. Recently, I upgraded TWRP to 3.0.2-0.
I have wiped system, dalvik, internal storage, cache and data everything went smoothly.
when i tried to install Rom zip i encounter and error that causing boot loop.
HTML:
mount: failed to mount /dev/block/platform/msm_sdcc.1/by-name system at /system: invalid argument
unmount of /system failed : no such volume
Patching system image unconditionally ...
flashing Supersu..
scripting succeed result was []
update partition details
...done
when i reboot, my phone goes in boot loop.
i tried with repair or change file system but still the error is same
my file system and format
/system ext4
/Data ext4
/cache ext4
Please Help to recover my mobile thank you...
flash the stock firmware, some times it fix this issues.
flash the stock firmware without flashing the recovery partition, and flash again twrp to avoid any issue, then flash temasek

Phone works but TWRP can't mount /data

Hello, I have this problem where TWRP is not able to mount /data, although the device still works without any other problems. This is preventing me to install XPosed, unfortunately. I have a custom ROM installed, although I can flash stock temporarily if required.
I've done an extensive Google search for this, and all the methods didn't help at all. TWRP can't repair nor reformat the data partition.
Here's the full log:
Code:
[COLOR="Red"]Could not mount /data and unable to find crypto footer.
Failed to mount '/data' (No such device)
Unable to recreate /data/media folder.[/COLOR]
Updating partition details...
[COLOR="red"]Failed to mount '/data' (No such device)
Failed to mount '/preload' (Invalid argument)[/COLOR]
...done
Full SELinux support is present.
[COLOR="Red"]Unable to mount /data/media/TWRP/.twrps[/COLOR]
I'm running TWRP 3.0.2-1.
Thank you for your help.

I looked into the TWRP fstab, and noticed that the partition types didn't match, so I formatted the partition with the correct type and reflashed the ROM, and now everything is going smoothly. Thanks!

TWRP on Swift 2x: Failed to mount '/data' (Invalid Argument)

Hi all.
I'm trying to make a last backup of the stock Android of my Swift 2x before flashing LineageOS. But TWRP (version 3.3.0-0) Seems unable to use the /data partition. I got various messages like:
Could not mount /data and unable to find crypto footer.
Failed to mount '/data' (Invalid Argument)
I tried to format the partition: Wipe -> advanced wipe -> repair or change filesystem -> change filesystem -> ext4 but it didn't change anything.
What's wrong? What can I do?
Thanks a lot for any hint.
bumping this thread as I also ran into this issue.
When using TWRP, the data and system partitions can't be mounted. they also show up as being 0mb in size.
Because of this, no backups can be made and a full system wipe also yields errors.
What I did was change the filesystem to ext2 and then change it back again to ext4.
Doing this at least allowed me to flash crdroid, but making backups still doesn't work.
Whenever i go into TWRP again, it's the same thing again: unable to mount and partitions show up as 0 mb in size.
Anyone know what's causing this?
Wileyfox encrypts there data when you factory reset your device or after youve rooted your device .To get around this you need to do a factory reset using stock recovery once thats done then turn off the device. Then using minimum adb and fastboot type (fastboot boot twrp.img) that will boot your already installed twrp now erase data internal storage etc you'll notice you can finally delete stock os youll see internal storage is showing mbs available again etc worked for me perfectly.

Which twrp version have you installed. And if you can still boot into recovery follow this steps .
1. Wipe dalvik cache and data.
2. Flash android 11 rom it should give error
3. Wipe dalvik data and cache again.
4. Flash rom
5. Format data.
reboot.
