Solved Grandstream GXP1628 - 3CX Updater installed unsupported (too new) Firmware

[ndom91]

Hi All,

Just installed 3CX for the first time and was in the process of installing the suggested updates.

I had added 2 of the Grandstream GXP1628 devices we have, so the updates included a firmware update.

So I thought, great - lets install that too.

Now after the install the phones show up in the "Phones" section entirely in red and under the FW column it says "Not Supported 1.0.4.82".

On the 3CX Phone Firmware page (https://www.3cx.com/support/phone-firmwares/) it lists version 1.0.4.125 as the latest supported version for the Grandstream GXP1628.

So my question is - why would it install an unsupported firmware version on its own, and is there a way now to downgrade these two devices?!

Okay so after much wrangling I was able to get it to revert (back?) to 1.0.4.125.

This can be closed
