[Android Q&A, Help & Troubleshooting] Kerrat:
Hi all,

Im trying to root my Doogee T3 but haven't been sucessfull so far. Seems like no one tried before or posted about it.

It has a

Mediatek MT6753,

so MTKdroidTools should work but it gives a few errors:

--->>> Connect to device <<<---

--- ERROR : --- TotalBytesPerChunk Not Found. Set default Page/Spare=2048/64 !!!

--- Unknown ROM structure, backup NOT possible!

ATTENTION! File /system/recovery-from-boot.p which restore factory recovery in case of phone switching on in a normal mode Is Found!

I tried to install twrp but it doesnt seem to work on this device. Happy if you prove me wrong.

I found a guide to root a Doogee F5, same chipset as the T3 so I gave it a shot.

(adb_log at the end, obviously a disaster)

Maybe there is a way to use the User2Root option of the MTK Engineer Mode? Like used in the F5 guide but I dont really understand what it actually does. I understand that its trying to change the linux-like persmissions and that it doesn't find anything, but thats it.

Lets skip this stuff:

-Yes, USB debugging and OEM unlocking are enabled

-Yes, I do have adb and fastboot

-Yes, I do have the drivers

-I already tried previous MTKdroidTools Versions

-KingRoot doesn't work

-RootGenius doesn't work

-Framaroot doesn't work

-I wasn't able to create a scatter file but found one for MT6753 online

adb log of Doogee F5 method:
