I make a port on CM14.1 for Umi Iron.
I can not test it because I do not have a phone ... but you can...
Now I will tell you what to do!
Before doing anything... Backup your (5.1.1 lollipop) rom on external sd_card
- Upload (CM14.1- Gapps) on the external sd_card.
First - Should flash (recovery.img) to see if it works?
Recovery is TWRP-3.0.2.0-MarshmallowPartitionLayout port on elefone p8000.
1. If works go and wipe all without the external SD card.
And install CM14.1, Gapps, (SU root - is enabled in developer settings)
Boot time 10min. (on my telephone).
2. If recovery does not work, you will need to go back and flash recovery 5.1.1 ,
and restore your backup rom (5.1.1).
Recovery may flash with (SP flashtool) or (Flashify) app on google play store.
Thank you matrix666.
Will fix it when I have more free time..
I work 12 hours a day and I do not have a lot of free time.
I hope you like it for the first time.
