Hi, I just run qd.pl --check on my bricked Senstation XE and parsed the output according to DMSS protocol documentation

I can see that Unlock command is not supported, don't worry about it, flash device and size codes are probably zero becasue it was designed for old NAND flash chips and became obsolete for eMMC (there maybe different command for this in newer protocol version) so nothing to do with eMMC health and last the dump command seems to me have invalid parameter size - it should be 24b address and 16b size but the script sends 6B. As phone responded NAK with code 0006 it seems rather this command is probably obsolete too and replaced by some 32b variant. Anybody have newer DMSS spec than 2011? Also I'm looking for what is the right MPRG????.hex file for Qualcomm MSM8260.

EDIT: Dammit, the eMMC died again during CM reflash, I send this HTC to hell. I give up the repair as probably every Sensation will die soon on eMMC bug...
