Decryption problem on TWRP - Xperia Z2 Q&A, Help & Troubleshooting

Hi
I have Mm 6.01 installed via adb sideloading from lollipop without any wipe. Somehow it worked.
The reason I had to do it that way is that phone is encrypted but when I boot to TWRP it does not recognise my decryption Pin so I couldn't flash from recovery.
I was using the seraja recovery.
Anyone got access to the encrypted partitions through TWRP? I don't know how to install TWRP 3.0.2 which might have a fix for the pin problem. Each way I try doesn't work. Any ideas?

Since you was on a twrp recovery so you made your bootloader device unlocked so you can easily install twrp 3.0.2 which maybe help you in solving your problem
To flash Twrp 3.0.2 follow this:
1- Download Twrp 3.0.2 from this link: https://dl.twrp.me/sirius/twrp-3.0.2-0-sirius.img.html
2- By using Fastboot you have installed on your PC, Put the twrp 3.0.2 you have downloaded in step 1 in the folder of ADB and Fastboot and you can flash twrp 3.0.2 by using this command: fastboot flash recovery twrp-3.0.2-0-sirius.img
If there is any question or a problem with this guide just tell me and i will help you
I hope that i had helped you.

Thanks for your response. Unfortunately, however, it doesn't work because the encryption prevents it writing to the partition.
C:\adb>fastboot flash recovery twrp-3.0.2-0-sirius.img
sending 'recovery' (11570 KB)...
OKAY [ 0.380s]
writing 'recovery'...
FAILED (remote: Command not allowed)
finished. total time: 0.403s
C:\adb>
Any ideas?

Sorry, I thought my bootloader was unlocked, but apparently not. Doh!

So your problem has been solved or not??
If not you have to unlock your bootloader which will allow you to install twrp recovery from adb command successfully.
Tell me the final result
