I've made a simple open source tool to help in the use of manually using EVGAs FirmwareUpdate.exe.
Have also included all the MCU firmwares from the start to present for RTX30 MCUs.

Disclaimer: You take full responsibility for its use, Dont blame me if you flash the wrong firmware and get a MCU boot loop.

Great!!!
Thank you

Does this tool only work on 3090 cards? I have a 3070 FTW3 Ultra and I would love to downgrade my MCU firmware to the previous one.

This is brilliant. If one bought an FTW3 Ultra (3 fans) and put a waterblock in it, would there be value in flashing to the HC firmware?

No idea, Its using EVGA own flashing program so id assume it would work if there have been any updates for your card.

Nope, MCU controls the fans and rgb which the waterblock just removes anywhere so they could be doing anything with no effect.

Thanks 👍 Yeah, it had an update recently and I would like to go back to the firmware that it had before. How would I go about getting that earlier firmware?:)

Select the first version of PX1 that supported that card and it should have the version 1 firmware in it.
Or you could always message EVGA asking for it.

Thanks. I'm pretty sure the PX1 version 1.1.3 is the one I want. Just installed the update and all is well. The last version that had this firmware version was 1.1.4 so I guess I'm stuck with it unless I want to update to the latest but I think it made my fans louder. Now I can test it out.:)
 
Thank you so much for this awesome software and your help:)
