Hello everyone,
I’m looking for all the previous BIOS versions for the Lenovo Legion T5-26IOB6 Desktop (Type 90RT).
Here are the system details:
- Model: Legion T5-26IOB6
- Motherboard Model: LENOVO 3733
- Chipset: Intel B560 (Rocket Lake PCH-H)
- Current BIOS Version: O54KT25A
- Lenovo Support Page: desktops and all in ones :: legion series :: legion t5 26iob6 :: 90rt Lenovo PC Support - Lenovo Support SV
I’m specifically looking for older BIOS versions because I’d like to downgrade from the current one.
Unfortunately, Lenovo only provides the latest version on their website, and I haven’t been able to find archived BIOS files elsewhere.
If anyone here has backups or official installers for any older BIOS revisions for this model, I’d be extremely grateful if you could share them.
Thanks in advance!
