I have sent an email to info(at)d5t5.com, hope they will come back with some help.
I have already cracked CEM PIN (it took about 5 hours with Mongoose interface / 530 atempts per second). With the rest I will work in coming day(s).
I have disconected the battery for more than an hour, re-connected (once with ICM power plug in + once without) than turn the ignition on, leave it and check. Did not work unfortunately.
It looks like the module is not fully bricked as it is responding in my version of VIDA after sending programming command (at least that is what I understand with my limited knowladge - CAN operational) by reporting on correct HW and serial number (in programing mode only). It looks like it does not start / was not flashed properly for some reason. The main problem is that I cannot see it anymore among modules (red in the overview).
VDASH did not show any error, after the last run of flashing it attempted to reboot and connect to the system and (I guess) could not read it out. Then switched to "recovering previous version" but since the module was not available (what I presume) it just quit.
