[HELP] [BRICKED] mt6589 device, Tecno F8, in bootloop - yaassyr - 2015-01-26
Hello guys
, i have a Tecno F8 mt6589 that got bricked in bootloop and continually reboot from the logo screen. I dont know what happened but i can access its recovery mode and the factory mode. i tried a lot of things to make it discoverable by my Windows 8.1 PC but this is what i see in the device manager: "unknown USB device (device descriptor request failed)", Trouble shooting doesn't work.When i boot into factory mode and made an auto test, the test result is:
[ x ] eMMc
[ ] Wi-Fi
and when i select the clear eMMc option it will just show formatting eMMc and suddenly, within less than a second, the phone reboot with continues bootloop. I dont know what happened with the eMMC
While in the system recovery mode i can do anything but i cant use the apply update from sd card option.
Please i need your help
Also, there's no sign of detection when i switch off and connect the phone to the PC, even if i remove the battery and replace it back. The phone only start as if its going to start charging then continue to its bootloop upon the connection
. It is only discoverable as "unknown USB device (device descriptor request failed)", when i boot into either the recovery or factory mode.

Do you have a full correct ROM for this phone?
