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?
