Repairing bricked HTC EvoDesign4G is easy with the RIFF Box. Phone is auto powered on with USB Data Cable connected to the PC while battery is connected.
Current resurrector works via USB interface thus no JTAG connection is
required. You may need to install RIFF BOX DCC Loader USB Interface USB
driver if you run this for the first time. Drivers are located in JTAG
Manager directory (Drivers folder).
In order to connect, device must be detected by system as Qualcomm
HS-USB QDLoader communication port. To force device into this mode (that
is if your device is dead but there is still no USB activity when you
connect it to PC with USB cable) use testpoint to disable the eMMC
memory – for this shortcut specified point on the schematics to the GND
during power-on stage.
Resurrector will reflash radio’s boot zones and will re-write PDA’s SPL
to 1.30.0000 version. Additionally to SPL and Radio zones, the zone
which contains Model ID is re-flashed too. Thus after resurrection phone
will have Model ID = ‘PH4410000’.
There is option to reflash BOOT and RECOVERY zones.
