Hello,

my Helix 2 (20CH...) has a very old Bios 2015 (1.83)... my files (update to 2.16) do not update this one.

Does anyone have files für older Bioses

1.92 (02-2017),
1.93/1.93-166 (03 &07-2017)
2.00 (06-2018)

and could manage to send them to me or tell my how to find/access those files (PM)?

Is there a tool (Lenovo), that could do the trick without intermediary?

Thanks in advance!!

Thanks,

I never had to look for very old files... and obviously i was not doing it carefully enough. Thanks to You and a TPader in Turkey, I got what I need...

But: I had to overcome some more problems, as under Windows 11/25H2 Update would not run as Windows did not like tdklib64.sys
(part of the updateprogramm. ) I had to enter Bios and end all security (Boot/Ram/TPM..) precaution, but no change...

Than I used an slightly older Win11-System and a system-ssd I had at hand, luckily, to proceed... and success I'm not quite shure, how (!) that did
work ...

Have a good an happy New Year, stay safe and well
