Decryption problem on TWRP

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?
