Gionee — How to unbrick my device

Hi Guys, Please I am in some serious mess and I need help. i messed up with my bootloader and now my phone seems dead. now here's what happens, the phone is completely dead and does not power on. any time i connect it to pc, it shows under device manager as USB Input device. under the tap 'HUMAN INTERFACE DEVICE (HID) the red light stays on for some time then it goes off. Actually i have all the necessary flash firmwares to kick it back to life, but the issue i am having is, my phone is not being detected by my pc. i installed Gionee drivers from the official webpage but still it won't detect my phone. it always sees my phone as 'USB INPUT DEVICE' i was told it needs to be detected under com port before my flashing sotware can recognize it. please Help PLease write to Mr. Wilson Alzate Escobar to email--> [protected]@hotmail.com
