I'm happy to share my TWRP 3.0.2-6 recovery, I ported it from the Elephone P9000. It's for Dual Sim only, please don't ask me for other models (Ultra inclued) I don't have enought time to build them all for now.
I think you just have to change the kernel with Carliv Image Kitchen to port it to your phone (never tested with this easy way), use my released recovery for your model as base for porting, same way for Ultra. Please report and share if working
In this version I fixed partition, you are able to backup and restore all 31 partitions ( except for Cache), all ext4 partitions can be mounted rw (be careful at what you are doing!!). And I applied a new theme (multilang).
Unlocking /data with password is not working.
Flash it with Fastboot.
See you !
