The normal battery icon for charging. It stays there for some time then the phone reboots but no tecno logo comes. It reboots again to the battery icon and the process repeats itself.

Hi. When i used sp flash tool to upload the preloader.bin file my tecno m3, now my phone only vibrates when i press the power button but the screen shows nothing. Now when i plug it to my comp to flash other files, my comp reads the drivers as mtk usb port instead of mtk preloader usb port which makes it impossible to flash the other files. Please help.

You installed mtk usb port instead of the preloader usb port

Тσ fix this u have тσ reinstall the driver again

1. Download MediaTek USB VCOM drivers
2. In Windows, go to Control Panel and open Device
Manager
3. Click any of the device groups you see there From
Action menu, select Add legacy hardware
4. Add hardware wizard will be opened, click next
5. Select Install the hardware that I manually select
from a list (Advanced)
6. Click next two times and click Have Disk button
7. Click browse and find where your driver's .inf file is,
then select it (the .inf you'll select is located in drivers
> USB Vcom driver > your OS) . Ensure to select the 64
bit .inf if your PC is 64 bit
8. Click Open and OK. You will see the drivers listed.
9. Select your driver there (select MEDIATEK PRELOADER USB VCOM PORT)
10. Click Next and finish installing.

N/B ..number 9 is very important ..that's where most pple do make mistake when installing this driver

Best тσ тσ this when the fne isn't connected тσ the pc

Just do as X3non instructed. Question for you, could you list all the files in your MTK backup? wanna be sure you have all needed files
