Now we will flash "Twrp" to the Moto e4:

Download Twrp image to your computer from this link:

https://mega.nz/#!pKJkiShQ!0T65Jc_a6BrQ45jGoimiwyncRu2rNpreeTNU20dNa9o

-copy the "recovery .img" to "/home" directory

-for flashing the Twrp type "fastboot flash recovery /home/recovery.img" (on computer terminal)

-twrp should start after a few seconds if not:

Hold Vol down + Power button for 5sec. until you see Android robot

Navigate to Recovery mode with volume rocker then enter with power button.

Now after few second Twrp will appear with screen "keep system read only" swipe the bar "swipe to allow modification"

-select "backup" select everything!

-backup

N.B:Don't reboot your device (after installation of the rom we will find a backup on the folder name "TWRP")

Now go back to Twrp menu and choose wipe->advanced wipe

Go to advanced wipe and check:

data,cache,system,dalvik->(wipe)

Go back to Twrp and choose install

Choose dotos rom zip file from externe sdcard and choose another time gapps file (optional)

Swipe to install

Wait to installation finish

Reboot to system (in Twrp menu)

First boot can take some more time just wait

when you are on dotos system you can now copy the backup TWRP folder to your computer using the usb cable(its about 3Go)

That's the steps i make to install dotos without root access make it on your own risk don't blame me if something go wrong , if you want to root your device search in xda forum, i read that we can install magiks for that option after installing dotos, exuse for my bad english.
