Today i discovered the JTAG pins of HTC hermes.
My device got bricked and was not able to boot anymore. Not even the bootlader came up.
Anyway i decided to do some investigation, there was nothing to loose
Thanks to Lt.Cmdr.Ivan who discovered the JTAG pins on the universal hardware.
(It made the step successful!!!)

(had to make a zip because high-resolution pix
) These are the testpoints to access Hermes main system Samsung MPU and recover OS bootloader!
To get access to the GSM chipset please have a look in the second post!

See the documentation in the archive for information how to build a LPT adaptor, to use this software!
The software tool has been modified to handle the /WP issue.
See attachment MSP_HERM.zip!
What ever happens to IPL/SPL on your device, it can be recovered quite easily now, using the JTAG method!
Added Olipro's 2.10 (Hard-SPL V7) for completeness.
This is a pure binary file, ready to flash via JTAG. Thanks again to olipro for this beautiful bunch of bits!!
Thanks again to scholbert,pof, cmonex, cr2, the_dipe and the others who gave useful hints or helped testing.
