Anyway, I've used your own auto twrp porter v1.1 and it has successfully ported twrp !
Then I flash it through my bootloader (using fastboot) and it successfully boots too.
But the problem is that : touchscreen doesn't work and I'm blocked in the Decrypt data screen (which request a password that I don't know). I can't do anything !
There is a screen shot here : https://1drv.ms/u/s!AmUA1o5VkY3XkXt1zrk4HOt2NM81
Also, when I reboot and return to recovery (either with adb or by holding vol up + power), my stock recovery comes back ! Weird right ? And I have to flash twrp again to come back to twrp interface.
