Creating a new firmware is an utopical ideia..i´m just exploring some ideas...
-the processor STI5518BQC, is used in many receivers (most common in american Pansat 2500)
-Ram ISSI IS42S16400B-7T, is used in some Wireless Linksys router´s
-EEPROM FLASH s29al016m90Ta101 (from Spansion), the only information i can find is from a "Media Center" device called Mediagate MG-35, and this one have a custom firmware...
Supposing that we pick up a firmware from a receiver that uses STI5518BQC, and having the commands for the FLASH, is not possible to get anything?
