Dell Vostro 3450 BIOS unlock!
Version A11: Advanced tab + Thermal Configuration unlocked (for Windows 7 only) - http://rghost.net/44461797 (by HairyCube)
Version A13: Same as above + Security Settings + OEM String removed - http://www.mediafire.com/?komxo57si198ltn (by TimeWalker)
Original unmodded A11: http://ftp1.dell.com/FOLDER00311153M/1/V3450A11.exe
Original unmodded A13: http://ftp1.dell.com/FOLDER00952500M/1/3450A13.exe
How to flash:
1. Open command prompt in the folder with the modded BIOS image
2. Type:
winflash.exe /BIOS /EC /SA /SV /BBL "BIOS1.WPH"
Another way to flash:
1. Run the official Dell BIOS update (V3450A11.exe)
2. Wait until it says "capsule is preparing to load into memory" and DO NOT PRESS ANYTHING
3. Go to your temp folder and replace Winflash\BIOS1.WPH with the modded file
4. Press OK to reboot and the firmware updater will flash the unlocked BIOS image
If you are experimenting with replacing UEFI modules, be extremely careful since it may break recovery mode and you won't be able to reflash in case something goes wrong.
If the BIOS you're flashing is the same version as the one currently flashed (e.g. you're flashing modded A13 over original A13), you don't have to include /BBL and /EC flags for winflash command line. Excluding these flags will prevent the flasher from touching EC and Boot block regions, which are essential for successful recovery.
If you mess up the boot block, you won't be able to recover your laptop BIOS without proper hardware equipment.
DSDT mods:
1) Fix MBT device detection. You need this to be able to recompile DSDT with iasl compiler.
2) Disable ST Micro Accelerometer. Disable it if you have an SSD or you just don't need it.
3) Remove KBC initialization check. Use if your touchpad and keyboard stop working randomly after restarting the PC.
For Intel+AMD GPU model:
For Intel GPU only model:
Same as Intel+AMD model, bit change 0xC5048C11 to 0xD9048C11.
To flash modified DSDT, you need to do the following:
1. Open BIOS1.WPH in PhoenixTool 2.14;
2. Set Manufacturer to Dell and press Advanced. On the right side, check "Allow user modification of modules", "Allow user to modify other modules" and "No SLIC";
3. Press OK, then press Go in PhoenixTool main window;
4. Once you get the message "Now you can make alterations in the DUMP directory", do not press OK. Instead, go to the DUMP directory and find the file with DSDT. In case of A13, it is 7E374E25-8E01-4FEE-87F2-390C23C606CD_1_946.ROM
5. Decompile this file using Intel ASL compiler (iasl.exe -d xxxxx.rom);
6. Open the resulting .dsl file and apply all mods you need. Note that you need to apply MBT device fix to be able to compile it;
7. Compile modified code using Intel IASL compiler (iasl.exe -oa xxxxx.dsl). Rename the resulting .aml file to 7E374E25-8E01-4FEE-87F2-390C23C606CD_1_946.ROM (for A13);
8. Replace the file in the DUMP directory with the one you just compiled and press OK in PhoenixTool. You will get BIOS1_SLIC.WPH in the directory with the original BIOS1.WPH;
9. Flash BIOS1_SLIC.WPH using WinFlash.
