The device need to be converted to Unified UserData partition - Cyanogenmod I'm trying to install latest Cyanogenmod on my Xperia T. But I get the following error:



Click image for larger version

I tried to install it several times.

NOTE : In my phone the microSD card is not detectable. So i cannot copy the zip and install it from SD card.
You really should've read either the XDA thread or the CM Wiki before doing any of this...

Migrate to the one big partition for CM-13.0 :

(Optional) Backup all your data, applications, internal storage, ...
(Optional) Empty the internal storage with the old ROM or TWRP 3.0
(Optional) If wished, do a full Nandroid backup from Recovery
Flash the latest ROM zip of your device to start the unification
Read and follow the instructions from the zip if anything goes wrong
(Optional) Restore your Nandroid backup if you want to
Flash the same ROM zip for CyanogenMod 13.0


So in other words, simply flashing the zip twice back-to-back will do.
Also, ditch CM recovery - it's not required and pathetically weak in function against TWRP. That will also allow you to connect to PC with MTP and put the zip inside the storage before flashing, which saves time if anything goes wrong (you don't need to adb push again).
