[How-To] Easily Unbrick Mediatek MT65xx Dead device

[avrilljay]

Hello!

I have bricked my Jiayu S3 3GB RAM/NFC Version during flashing Firmware with SP Flash tool. Now I can go in META-Mode when I hold Volume - and connect my Phone to PC. My Computer try to install Driver but the worst Thing is that my Phone reconnect automatically and it Shows me the Message: "Device removed" after installing Drivers although I have my Phone connected to PC. On Device Manager it shows a short time : "Unknown Device" and then it reconnect but It Shows nothing on Ports (COM & LTP) : Mediatek USB VCOM (Android) (COMx). So my Device is dead and I can not get it to work and turn it on again.
META Mode is working but it Shows nothing on COM Ports on Device Manager. I don't know what I can do.
I NEED MY PHONE. Please could anyone help me to solve my Problem! Sorry for my English

Hi have you found solution to your problem? Am having the exact same issue with my gionee gpad g2 don't know how to go about it, device manager detect my device as unknown all drivers installed don't seem to change anything. Just hope there is another solution to this problem,
