How to Repair Boot Dead This PHone.

Code:

How can i repair it ?

you have to disassemble your phone and take pcb out. check there should be some Golden points. check these points there should be written on them Rx,Tx,GND,Vcc,Vcharge etc... check there should be written "COLO" or "KOLO" or "KCOLO" you have to Sold that point with GND After Sold Attach usb now your phone will detect with USB !! and now ready to Flash.
In some phones "COLO" or "KOLO" or "KCOLO" not written for those type of phones you have to test all points one by one Short Golden point with GND and attach usb cable which point short with gnd can able to detect your phone by pc is Force Preloader Mode Test Point !! Keep in mind Don't Short Vcc,Vcharge or any other pin which have 4.x Volts also i had tested "Colo" or "Kolo" or "KCOLO" don't have any kind of volts..
