Phone was at 8.2(1) and with CCME 8.0 the upgrade goes to 8.5(4)
As far as the capture goes, there is not much to see. I will attach it when I can. I have had debug tftp events on and nothing from that and it is also the same on wireshark...nothing. When a working phone is reset, I do see the TFPT debog login prompts show up.
One strange item:
I disabled the router at the DHCP sever and used tftp32 as my laptop with Option 150 turned on. With wireshark on, I could see the 7941 broadcasting a DHCP request and tftp32 answering....but the 7941 would ignore the response and keeps broadcasting a DHCP request. When I turn the DHCP back on in the router, the 7941 gets its address but stops doing anything once the address is received. It seems almost as if the phone is not recognizing its TFTP server address and never starts requesting its default load.
Have you tried a pre 8.5.2 firmware?? To get to 9.x or 8.5.3 (4) you must
step through 8.5.2
Firmware Upgrade Issues for SCCP
Note For all SCCP firmware upgrades from firmware release versions earlier than 8.3(3) to version 8.5(2)SR1 or greater, you must first upgrade your firmware to version 8.5(2). Once you have upgraded to version 8.5(2), you can upgrade your IP Phone to version 8.5(2)SR1 or later.
Have been trying to reload a pre 8.5.2 load. For what ever reason, the phone does not boot properly and never tries to TFTP to the server. Maybe when I plugged it into the upgraded system without going through the 8.5.2 load, the upgrade process screwed up something within the phone boot sequence.
