T54w stuck on welcome after power fail
I have 12 T54w phones at a customer and had a power failure long enough the battery back up times out. 11 of the 12 came up without issue but 1 is stuck at the Welcome screen. I have tried to factory reset but doesn't solve the problem. Any suggestions? Is there documentation somewhere to resolve this?

You can use the recovery method explained here:

You have to make a recovery USB or use TFTP to get the files to the phone. With the files you get a manual how to proceed.

Good luck.

You should not even need to do a TFTP/USB recovery with the need for recovery files. On the new phone models (like the T54W) there is a built-in backup system that can be used for recovery:
