So im curious, I see alot of need for a stock firmware for a device i just got zte sonata 3. Heres what id like to do, once rooted, somehow (ill go on to learn if possible) make a backup of the stock rom. Once i have it, is there a way to modify boot.img to allow twrp? Or rid bootloops after uninstalling system apks and such? I recall in the past a term Loki'd boot.img. any insight? The underlining question being with root and a locked bootloader what can be done to install twrp or prevent bootlops. (I understand mare rhan basics like dont mess with system or boot.img and such, build prop as well i believe)
