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 mt6750T 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.
