As far as I know bios for dm1z-3000 is not hackable and there is no tool at present time which completely can remove whitelist restriction. Having this machine I dumped bios and tried to replace old wifi IDs to new one. After changes the main issue is to flash bios with new modified image. I tried several times with different tool: placed 01611.bin (from dump, 2 mb) instead of 01611.bin (actual, 2.18 mb) in Insyde Flash Utility folder with .bin image (archive sp50519.exe for F.03 and archive sp52331.exe for F.05) - got error wrong signature. placed 01611.bin in HP_tool/Hewlett-Packard/Bios/New and P_tool/Hewlett-Packard/Bios/Old on usb stick and tried to flash bios after startup-F2-bios management - got wrong signature error (If I place here (Bios/New) old unmodified image 01611.bin with .sig file, the utility flashes bios well) used flas**t 1.4b to flash from DOS and get netx errors: Code: C:\>flas**t 01611.bin Error: IHISI 10h fail. Internal Error 20 FBTS: Permission is denied by user and Code: c:\flas**t /x /mc 01611.bin Chipset Support : ICH8 Flash part Support : SST25VF016B Detecting Chipset...... Error: Chipset not supported As far as no one tool can help me I am asking for help, was anybody able to flash modified bios on dm1z-3000? Or may be someone could suggest another tool to try with? Thanks in advance! Help is much appreciate.
