I'm trying to mod the bios for the Toshiba Satellite L350D. I'm using the Phoenix tool 1.28, and the bios is an Insyde bios, version 1.70. I followed these steps: Updated the bios to 1.70 using the official update Installed the RW report version 1.4.7 Selected the ACPI tables, Ctrl+F2 to save, filename unmodified. Stored both the original bios and the rw report on a folder named "original" Opened the original bios using the Phoenix Tool, and look for the exact name for the existing 2.0 slic from toshiba (it's TOSINV) Used the SLIC 2.1 bins 7zip file from date 3-22-10 and extracted to a folder the TOSINV slic and certificate files. Used the 2.1 TOSINV slic file, and the rw report file on the Phoenix Tool, verified the certificate (verification was Ok) Without modifying any more options, I generated the SLIC bios. The file was created Ok, then I moved the SLIC bios to a folder named "Mod". I renamed the file to its original filename (so the flash utility finds the file). I modified the platform.ini file for the InsydeFlash utility to enable interactive (manual) mode. (The original configuration prevented me to flash the same or older bios versions) I flashed the bios, I installed the certificate, I used a serial number; but Windows does not activate. I used the rw report program to look at the SLIC on the bios, and while there is a TOSINV slic, all the data of that slic is blank. I saved this report to the "Mod" folder I tried to flash from DOS, I tried playing with the settings in the "Rom protection list" page from the InsydeFlash utility, nothing worked. If I open the modded bios from the Phoenix Tool, it says that the SLIC 2.1 is vallid, but I don't know if this checks the integrity of the SLIC of it only cheks if it exists. I packed the original bios and rw report, and my modded bios and the resulting rw report, the SLIC bin file and the certificate on the RAR file that can be downloaded from here: http://www.mediafire.com/?zzoz0zbnjdd I don't now what to do from here. I will thank any ideas of what's next to try.
