Initial version
It is possible that RM-36 (6680) device security area will get corrupted in
certain cases. Corruption gives “start up failed – contact retailer” message to
phone screen on start up. If flashing new software doesn’t work it is possible
that the root cause is corrupted security area.
Fault is very similar as in RAP3G or HELEN fault so it is very important to
check, if the problem is corrupted security area.
Do not scrap phone with
corrupted security area because this can be fixed now.
