mount: failed to mount /dev/block....

I had the same issue. Flashed with nandroid backup using TWRP. Don't root if asked afterwards. Flashed correct recovery for that backup. Update and it should take.

Re
Maybe first of all you two write the steps performed for flashing Lollipop Roms? I've tried all the Lollipop Roms compiled for SXS and nor,ally I used to do this way:
1. TWRP recovery (but CWM also worked)
Install TWRP recovery in FOTA partition using Terminal apk provided your phone is running on 4.1.2. kernel supporting TWRP recovery. Flash kernel from ROM zip file prior entering TWRP (this step helps avoiding an error like "update binary...").
2. In TWRP recovery - Advanced - wipe everything but sdcard. In Mount section unmount everything but sdcard.
3. Flash the ROM and wipe Cashe&Dalvik
4. Flash appropriate GAPPS, wipe Cashe&Dalvik and reboot.
that's all

error executing updater binary

trying to flash a cyanogenmod rom onto my rooted phone with TWRP.
Everything okay up to the point on installing the new rom (a zip file).
here's what i get as an error message:
***********
E:Error executing updater binary in zip '/sdcard/<rom_name_here>.zip'
error flashing zip
updating parition details...
...done
****************
I've tried with all the recent cyanogenmod builds for the htcone m9 and I get the same error everytime. Even when i try to sideload from my computer in adb.
I've also seen this error in other forums and they have suggested doing certain wiping procedures and reboots, but I've tried them all and I've gotten nowhere.
any ideas?

TWRP and "No OS installed" and failed to mount /System (Permission denied)

As explained in an other thread i got this issue :
with TWRP-offain and original one downloaded from TWRP website i received this error message after installation attempts of different custom ROMs
No OS installed
I wiped System and Data partition on each A and B slots and then tried to install on each slots some custom ROMs
At the end of each installations i received also this error message :

You need to use this twrp. Then it will work. About twrp errors: just ignore...

I've already used also that TWRP version
twrp-installer-daisy-3.3.0-0-offain.zip
KO
