【变砖求助】手机变砖了，刷不上，大牛看看有解没~！！

imdong

插上USB以后，返回这个“Enter USB Download... Failed to receive echo command - 0x0”
然后自动往下，卡在了 “Capturing image...”

这就是全过程，论坛的两个置顶刷机包都试了。

Download port:  com4
Enter USB Download... Failed to receive echo command - 0x0
OK
Download port:  com4

"save addr=0xA0000 image=sysparm_dep_backup.bin"

image_size = 0x20000
Capturing image...

手机现在开不了机，没有任何反应~！！！手机是 OT906~！！

最后结果

Download port:  com4
Enter USB Download... Failed to receive echo command - 0x0
OK
Download port:  com4
"save addr=0xA0000 image=sysparm_dep_backup.bin"
image_size = 0x20000
Capturing image...TOOL_ReadComPortWithTimeout timeout = 10!
Error, read com port failed.Timeout

ERROR! save calibrate data fail!!!
请按任意键继续. . .

重启电脑结果照样的~！
