36.82.0.30 firmware T41 upgrade to V83
Chaps,
I am planning a gradual upgrade of my estate to V83 firmware but find i cant upgrade a t41p because it seems 36.82.0.20 will not upgrade to 36.83.0.10 and there is no rom file on the download page for 36.82.0.30 (there is on all the other t4x series)

the right answer to what might have been the wrong question formulation. ~As far as I can see 36.82.0.20 will not upgrade to 36.83.0.10 and requires the interim step of uploading to 36.82.0.30 first - All the other devices in the list have a x.82.0.30 firmware but t41p does not.

Hi Chris,

I think your assumption is not right.

As far as I know you can upgrade directly from 36.82.0.20 to 36.83.0.10. I personally never have any upgrade issues when I skip a f/w release of 1 or more. And never have to use an interim step.

Please read the Release Notes, 1. Introduction, Firmware version on page 2/27 where you can read “T41: 36.82.0.20 upgrades to 36.83.0.10”
I cannot find any notes about interim steps.

Maybe I do not understand what you mean?

Best regards,
Frank.
