[REQUEST] Sony VAIO VGN-NR300 & VGN-NR400 Series (R2060J9) BIOS Unlock

[Phantom_R]

Hello there!I'm trying to get an old mod, the same an user requested many years ago, I don't if it's possible but I'm trying everything to make this work. The reason: The laptop in particular s (SONY VAIO - VGN-NR330FE) supposedly does support 4GB of RAM, yet when I try to hook them up, Windows just crashes (Win10), but when I only have 2GB connected, then it does work. I thought it could be the frequency of the cards that are having an issue, that's why I'm trying to fix it with the mod.
Many thanks in advance to anyone who can help me with this.



The rams that I have are: 2GB PCS2-5300 CL5 200-Pin Sodimm Kingston.

Your laptop is based on GL960 chipset. It has hardware limits for memory in first slot. It can't be solved by BIOS mod.
Install 1GB in first slot and 2GB in second.

You were absolutely right. It worked that way! It's not 4 but still better than 2GB!

Big thanks

In need of a bios unlock and any whitelist removal if any exist. Need VT as I upgraded the CPU to T9500. No restriction to overclocking If possible and 800MHz ram recognition from bios as I know this board can use 800Mhz but sees the ram as 667MHz.

There is currently no official bios available from Sony's website as legacy files no longer exist.

Laptop model: SONY VAIO VGN-NR498E  / PCG-7133L
Bios model: Phoenix
Bios version: R2060J9

I have attached a bios picture for reference:

I used Universal Bios Backup ToolKit 2.0 and it made a .rom file backup.

Edit:
After much research, found out that the UBBT doesn't completely backup certain registers and because its a dump bios and not original, its tricky.
I have used SLIC Dump tool to save my BIN,Cert and key files along with SLIC.bin file. Used RW Everything to get the ACPI tables RW file.
Used Phoenixtool and it gave no errors. Everything matched and it was able to make a modified R2060J9 bios file.
I tried to flash with Winphlash (used older version and Secure Winflash version) and get the same error along the lines of:
"Corrupted interface descriptors in the new BIOS file
Part Table Signature not found in the interface
Error code: -161"

This could be correlated to how the UBBT dumps the bios file and is not an original (since it's not available officially) bios file. To get a proper dump file to work, I saw this thread on another forum:
https://forums.mydigitallife.net/threads...ios.21120/

Post#1 and #6 provide possible solutions but they are very tedious.

I even tried to flash the dumped bios file without mod and it still gives same error.

My only option is if someone knows how to properly mod the bios file to make it work or has a working bios rom for this bios version.

Will pay for your efforts if it can be done.

Did anyone ever succeed in modifying this BIOS?
