Hello everyone and congratulations for the site: the forums are really well done and the tutorials are made so that even one not very practical understands them.
I have a doogee BL7000 (mtk 6750T processor, Andoid Nougat) and I would like to get root permissions. I know, however, that to do this I have to install the recovery twrp and that to install twrp. I have to unlock the bootloader and that when I unlock the bootloader I lose the imei. Then I should backup the imei before unlocking the bootloader. It can be done without root permissions? The methods to insert them after the I tried them all, but they do not work.
Sorry, I do not speak English, translated with Google translator.

You can root without unlocking bootloader or custom recovery.
What's your phone's Build Number and do you have the firmware?

Thanks for the answer.Di methods I tried 3857724, I made the flash of the phone as many times, installing and trying programs with the antivirus disabled I had to format it 4 times ... will be the right time or I'll have to choose between a phone with root , but without imei and a telephone with imei, but without root?
This is the build number
