I have a Miroir M20 which I have dumped the SPI flash from using an SPI programmer. I am not sure if this will help cracking devices without disaTest or not. The zip contains a raw dump of the Winbond W25Q16JV SPI chip as well as a strings dump of the contents and a text file containing the UPC, DiSa number and Product ID. I do not know what Product ID is, it was on the Walmart site when I went to get the UPC as I do not have the box for the projector atm. I also have another unopened projector which I can dump if needed. Assuming the projector might perma lock if the wrong code is entered too many times, I assume the flash can be restored so more codes can be tried.
UPDATE: It does not appear to track invalid code entries and the flash does not change after multiple failures.
The processor used is an RTD2668 and this uses an 8051 as the CPU in case someone wants to attempt disassembling this, so far I have had no luck.

EDIT: I added the Walmart # just in case this matters to the code, though I doubt it does.
