TWRP constantly crashing and rebooting back

Question

My phone (Nexus 5) is constantly rebooting to the TWRP screen where it crashes, shuts down and repeats.

TWRP error:

Could not mount /data and unable to find crypto footer
Failed to mount '/data' (Invalid argument)
Unable to recreate /data/media folder.
Updating partition details...
Failed to mount '/data' (Invalid argument)
...done
Unable to mount storage
Failed to mount '/data' (Invalid argument)
Full SELinux support is present.
Running Recovery Commands
Failed to mount '/data' (Invalid argument)
Formatting Cache using make_ext4fs...
Done processing script file
Renamed stock recovery file in /system to prevent the stock ROM from replacing TWRP.
Failed to mount '/data' (Invalid argument)
Failed to mount '/data' (Invalid argument)

What I did before I broke it:

1. Shut down the phone.

2. Booted the phone into the fastboot mode. (Pow + Vol Down)

3. On PC (through USB cable) I ran these commands:

   • fastboot oem unlock -> which asks for an agreement and deletes the whole system

   • fastboot flash recovery Downloads/twrp.img - I had the file renamed and it was located in the Downloads folder

4. Rebooted to the Recovery mode (2x Vol Up and Pow)

So what am I supposed to do to successfully flash a custom recovery if not this way?

Answer 1

I also faced with this issue and I found solution.

Go to bootolader and then execute:

fastboot -w

to wipe the data from the phone (it will erase all user data and internal storage)

after that go to recovery by calling:

fastboot reboot
