g9-593 how to rollback to default bios?

xrolexx

i am currently running the last version of bios 1.14. I dont remember what version of bios my laptop came with. I want to downgrade to the one it came with.

I'm pretty sure you can't downgrade the bios (someone correct me if i'm wrong) at least it won't allow it via normal installation, and even if it would why would you want to downgrade as the upgrades are made to fix issues not to create

Open bios exe.

It will fail.

Then dont close the exe.Before closing it, 

Go ; C:\Users\name\AppData\Local\Temp\

Search for a folder named (randomLetters).tmp

There should be a H2OFFT-W.exe and zrt.rd file in there.

Just copy this folder and close the failing install.

In that copied folder, edit the platform.ini file.

[BIOSVersionFormat]

;[nb4-version] +

BIOSVFEnable=1

VersionFormat=XN.NN

TO

[BIOSVersionFormat]

;[nb4-version] +

BIOSVFEnable=1

VersionFormat=XN.DD

The VersionFormat value now has 'XN.DD' instead of 'XN.NN'.

This will ignore the fact that 1.19 -> 1.1x is a downgrade.(x<9).

Run H2OFFT-W.exe.

That won't work as written.  I just downgraded my G9-593 from 1.13 to 1.14.  It's close but not quite right.

BIOS_113.exe is just a self-extracting archive, so it can be extracted right where it sits, rather than messing around with the temp folder.  Most importantly, the version format needs to be "N.DD". 

Here's a full set of instructions - the way I rolled back my G9-593 BIOS about 15 minutes ago.

1. Download "7zip" if you don't already have it --> https://www.7-zip.org/
   
   
2. I'm assuming you already have BIOS_113.exe extracted and ready in a folder somewhere.
   
   
3. Right click on BIOS_113.exe - expand "7zip" menu and choose "Extract to "BIOS_113\""
   
   
4. In the newly created "BIOS_113" folder, find "platform.ini" and open it in a text editor
   
   
5. In platform.ini, find line #449 or search for "VersionFormat=XN.TTDDDDD"
   
   
6. Change it to "VersionFormat=N.DD" and save
   
   
7. In BIOS_113 folder, run H2OFFT-Wx64.exe
   
   
8. Follow on-screen instructions and flash back to 1.13

My thanks still go out to Red-Sand, for putting me close enough to the right track - saved me some time.

Cheers and be well.

Downgrade 1.13 to 1.14 that's upgrade to me not downgrade either you wrote it wrong or its what I just said I'm guessing it's the first one 😊
