newest firmware for T4XS units causes bootup loop
Be wary of the latest firmware for the T4XS family (verified on T46S and T48S)

It causes a boot loop when connected to the Internet.
Boot loop as displayed on phones screen:

Welcome Initializing…Please wait
Regular screen for 3 seconds
Config Updating
Update Skipped
Welcome (assuming a reboot happened)
Regular screen for 5-10 seconds (all the above seems normal)
Reboot (oops, back to top)

The fix is to set static IPs (no Internet access) and revert back to, no boot loop without Internet access.

I did try turning off auto provisioning, no change. Couldn't find anything else to try.

The 2 devices are part of a customers network, so I cannot really do much to test, I may have to buy an S model for my lab.

It’s also interesting the variance of firmware versions available on the Yealink site, and what 3CX has approved. Some 3CX phones have a higher firmware revision than what’s available from the Yealink site. 3CX likes for the S model phones.
