Hi.
I have a bricked X7500. I get a blank bootloader (i see only the stripes no other info) and i guess that the only way to make it work is to find the jtag pins and repair the bootloader. Could you help me or give me directions on how i will find the jtag pins?.... Thanks! P.S. thats the X7500 motherboard (IMG:http://i149.photobucket.com/albums/s67/nicktgr15/x7500.jpg) |
