[REQUEST] Unlocking Vaio PhoenixBIOS R0174J3

[Sml6397]

Hello sharkonholiday & mhetru,

I have already unlocked this BIOS in the past. Here is a link to it.

Hi,

It's possible update bios R0172J3 to this version directly without update bios to original R0174J3? My problem is that I can't update to original R0174J3 because program provided by Sony doesn't works with windows 10.

By other side, i don't know how to boot from USB. In my Bios version, only appear this options:

Internal Optical Drive
Floppy Disk Drive
Internal hard Disk Drive
Network


Any idea?

Thanks in advace,
Dani

Hi, I own an old VAIO VGN FE31B and flashed successfully the modified BIOS, however the CPU control menu is empty, all the other things are fine, and thanks for the work done. Is there anything I can do to make something appear? That was my 1st BIOS flashing and I was scared like [censored] lol, my VAIO is stock hardware configuration, with Intel Core 2 Duo T5500 and 1 GB RAM DDR2, 80 GB HDD and Nvidia GeForce Go 7400

Sony VGN FE670g OS windows 7 32bit
Current bios version, Phoenix RO174J3
Trying to add new life to good old laptop
Would like ACHI mod enabled and 4gb of memory as well
Tried to back up bios with phlash16 from here to submit but got an error message.
Have used phlash16 before without problems. Any help would be appreciated.

Thanks Steven (Sml6397) and other Mods for your work and explanations in above posts.

However I have the same model as JS95 above (whose post confirmed success) but I could not flash the modified BIOS R0174J3.

I have followed the steps you have given to Guaruska, and below are the errors
(trial A means specified "bios.wph" as BIOS file,
trial B means specified "Templat0_mod.rom" as BIOS file;
"Error code -103" has message "corrupted interface descriptors...platform signature not found in interface",
"Error code -161" has message "corrupted interface descriptors...part table signature not found in interface",
"Error code 87" has message "failed to retrieve system BIOS info, the parameter is incorrect" ):

1) using WinPhlash v1.0.0.18-- trial A is error 103; trail B is error 161
2) using WinPhlash v1.4 build 08130--trial A is error 87; trial B is error 161
3) using WinPhlash v1.6.1.1--trial A is error 103; trial B is error 161
4) using MSDOS Phlash16 v1.4 build 57--error is 103
5) using MSDOS Phlash16 v1.6.8.4i6--error is 103
6) using MSDOS Phlash16 v1.6.8.4--error is 103

Just to recap, my model is Vaio VGN-FE21B, and I have installed Win98 and used its DOS to try the above 6 runs, using USB boot. But all WinPhlash or DOS Phlash have error codes.

Could you please help or advise if I have done something wrong or missed something? I just want to upgrade CPU from its stock 32bit T2300 to 64bit T7200 and 4GB RAM.

Thanks in advance!
