Check phones pull-up resistors on CMD, DAT0.
They are recently broken after soldering.

Best Regards

Sir Every HTC handset does not power on after checking EMMC in Z3X Box. I am using Moorc JTAG ISP Adaptor with my Easy Jtag.

Hi,
Please, measure real voltages of your ISP Adapter.
Some adapters have mistake in voltage text (1.8 and 3.3 are swapped).
If you solder VCC 3.3V to VCCQ 1.8 , some Qualcomm CPU can be damaged.
In this case phone doesn't start up.
Best Regards
