[Q] Trouble (recovey mode) with [GUIDE] Back up DRM Keys & unlock/relock Bootloader

Hi,

I am stuck with the rooting of my Sony Xperia Z1 Compact following the [GUIDE] Back up DRM Keys & unlock/relock Bootloader (noob proof) and I hope you can help me. Everything worked fine until

17. Now format /system (located under Mounts & Storage) (Important: Do NOT reboot until advised so or you will have to start again)
Error message: Error formatting /system!

When I start recovery mode and start PhilZ Touch 6 I get the error messages:
Can't mount /cache/recovery/command
Unable to create brightness sys file
Can't mount /cache/recovery/logs
....
I also found that there might be a solution for it:

While in Recovery I had to flash lockeddualrecovery before anything else so partitions would be restored properly, then reboot and repeat step 19

But what does this mean? It sounds for me that I have to install the Z1C-lockeddualrecovery(...)flashable.zip first, in the menu I go to Install Zip, Choose zip from /sdcard and I get the error message Can't mount /sdcard.

How can I flash the lockeddualrecovery? Or what else could you suggest?

Thanks a lot for your help.

-> I found the solution, I have to boot with volume down first, use the alternative recovery app to install the .zip and then repeat step 19.

Regards
Michael
