Hi All,
We got a bunch of used 5220 phones and are trying to get them on the same boot firmware version so our techs can configure the phones from the same instructions.
We did the regular upgrade procedure by holding down 7 while powering up and pointed them at the tftp server on our 3300.
All the 04.xx.xx.xx phones upgraded to 04.05.00.02
All the 02.xx.xx.xx phones upgraded to 02.05.00.04
How can we get the 02.05.00.04 phones up to 04.05.00.02?
EDIT: I think I answered my own question. All the 02.xx.xx.xx phone are dual mode, so I guess they run a completely different version of the firmware.
Thanks in advance
-Santi
