Couple of things to try:
1. Connect the non working phone to a switchport where a working phone is connected
2. Factory reset

Try deleting the ITL files on these phones and try again.
1. Hit Settings button on phone
2. Select Security configuration
3.dial **# to unlock settings (Verify this from the "Lock" icon at top right corner of phone screen)
4. Scroll down to ITL File
5. Select Erase and try again.

Thank You!
I understand your PC is connected directly to the phone port of the SW?
Standard Ethernet cable or a crossover cable?
I'll try.

I'm sorry, but that did not work.
The phone also does the same thing.
By downloading the term45.default.loads, but not the other files.
The phone wait some minuts and restart again and again.
I tried the full file system format (3491672850*#) again and simple factory reset (123456789*#).
I attached the TFTP log.
I dumped on my linux the phone network trafic, look 7945tcpdump.txt.
I tryed linux TFTP, but some as for windows, phone downloaded the term45.default.loads, but no download the another files.
I tryed differenf firmware and SIP and SCCP firmware.
Thanks.

These phones I believe have a requirement regarding versioning of the software depending on the hardware revision (if it's fully back to bricked) or depending on the currently loaded revision. One results in a HC check fail and the other an auth fail - when you can see the message.
Make sure you are trying to load the proper version to the phone, otherwise once it grabs the file it will not load it up.
This is one of a few reasons that you would not want to add entering the factory default erase flash code to your list of troubleshooting, if only that you may have to go out of your way to restore the device.

Hello,
OK.
I am understand what is the ITL and CTL files. :-)
But, why don't erase this files the phone filesystem format (3491672850*#?
The file don't stored the flash?
And, how to delete this files from the blank screen dead phone?
