CyanogenMod stuck on boot screen Xperia Z

I just installed CyanogenMod using the instructions from the CM wiki using the latest STABLE release.
When I booted my device, it was stuck on the CyanonMod loading screen (blue looping circle). I've wiped and reinstalled multiple times but cannot fix the problem.
I used the ClockWordMod "show log" command from the advanced menu, and got this:
I : Can't partition non-vfat: datamedia
I : Can't partition non-vfat: auto
I : Can't format unknown volume: /emmc
mount: mounting /dev/block/platform/msm/sdcc.1/by-name/userdata on /data failed: Invalid argument
W: failed to mount /dev/block/platform/msm_sdcc.1/by-name/userdata (Invalid argument)
The last line probably refers to my attempt to wipe the dalvik cache
I've noticed that CWM can't mount /data

Solved by installing TWRP recovery. Apparently CWM does not support encrypted partitions.

Data recovery, how to mount messed up /data - Internal SD - sda25 in Recovery/ADB

Hi:
I've messed up my Note 9 pretty bad, such that no partitions mount in TWRP except cache - I'll need to do a data wipe, but I need to save data that I have in the Internal SD.
I've discovered via fdisk in TWRP that the media part - the Internal SD is partition sda25 - however can
t mount it in the terminal through a simple: mount /dev/block/sda25 /mnt
I get an error: mount failed: Invalid argument
I've tried: mount -t sdcardfs /dev/block/sda25 /mnt
This gives me also an error: mount failed: Not a directory
Mounting with -t vfat or exfat gives the Invalid argument error.
Anyone can help me with how to mount it, so that I may copy data off of it manually? I don't want to lose it. Many thanks.

cant you simply wipe the affected partitions(except data of course)? then flash a rom?
have you tried;
mount /sys/block/sda25 /mydata
or
mount /dev/block/sda25 /mydata
or
adb
mount -o rw /dev/block/sda25/data /mydata
in both cases /mydata is just the mount point so I believe it can simply be called what ever you want including just /data
have you read:
https://android.stackexchange.com/q...data-partitions-in-recovery-mode-in-adb-shell
edit:
by any chance when you first flashed twrp, did you forget to format data?
if yes then flash back stock AP file(original phone's firmware) in Odin AP slot only and you should be good to go.( you shouldn't loose any files in internal storage)

Question Every custom ROM I flash is stuck on their bootscreen

Hello.
I have a Redmi Note 10 Pro (8GB RAM Version) with an official unlocked bootloader.
I have managed it to install TWRP, TWRP works, that means, I can boot into it, and use it.
But if I flash a ROM ZIP file over TWRP, every custom ROM gets stuck at its bootscreen. It shows the
bootscreen of the offending custom rom, then nothing happens anymore, its just stuck there.
Does anyone here know, wht I do wrong?
Regards

Try flashing the fastboot firmware using pc so that it may fix corrupt partitions, if any.
or maybe the universe is conspiring against you

Can you tell me how I do that (Flashing over pc?)

Try to format data with yes before and after you flash a ROM via twrp

Tried to format data with yes, shows following errors:
Failed to mount `/system_ext´(Invalid argument)
Failed to mount `/product`(Invalid argument)
Updating partition details...
Failed to mount ´/system_ext`(Invalid argument)
Failed to mount `/product`(Invalid argument)
...done
Full SELinux support is present.
MTP Enabled
Done.
You may need to reboot recovery to be able to use /
data again.
TWRP will not recreate /data/media on an FBE device.
Please reboot into your rom to create /data/media [Note from the narrator: Thats not possible, every ROM stucks on boot]
