I have been trying to flash a Dell Inspiron 1520 from the factory 2.0 slic to 2.1. I downloaded the bios file from Dells website and used Andys tool to mod the bios with success. When I flashed the computer it was successful but when I checked it still has the 2.0 slic. I then downloaded a modded bios from here which has been verified to work. after a successful flash I still have 2.0 slic. I have tried earlier versions of the bios with the same results. Other people have reported success with flashing this model. Could my bios be locked somehow to not be able to change the slic. Any help would be greatly appreciated as I have never had this problem and I'm running out of ideas. Thanks in advance.
