RE: T48 stuck in boot
i have the same problem on a brand-new T48 Phone. I've done a firmware update over auto provisioning and it hangs in the update process.
After an hour wait, i disconnect the Ethernet (POE).

Connect again and the phone is standing in the first boot screen.

i turn on my TFTP Server and try to upload the 3 Files. Jim, your links don't work. I found these Files somewhere on the Internet. Please make these files available on the Yealink Support Page. There is only the ROM File in the download Area.

now my point is, that the firmware upgrade process over TFTP also depends.
the T48 Phone loads the 2 Files up and start the upgrade process. Then it loads the ROM File an it freeze.

Could it be that the Firmware update doesn't work with POE? I've ordered a PowerSupply and will try the update tomorrow...
