You first need to add all of the files to your TFTP server and then specify either at the phone level or at the device default level what FW you want to use. Then reset your phones and allow them to upgrade to the new fw
I'm going to assume you already have the files for your phones -- the following instructions won't work unless you do. Unfortunately, this only really works for small-scale upgrades. If you have a ton of phones it will take a long time...
Download tftpd32 (see the bottom of this post for the link) and install it on one of your computers.
Run the program, and enable the DHCP server in the settings. Be sure to provide option 150 in DHCP (that's what the phone is looking for).
Place your phone's firmware files in the tftp directory.
Connect the phone to the computer (with the phone powered off) one of two ways:
1. Directly to the NIC on the computer using a crossover cable. (it won't work unless you use a crossover cable!)
2. Through a hub (no crossover cable required), with no other DHCP server connected in this configuration.
Plug in your phone, and immediately hold the # key while it powers up. When you see the screen prompt about the "reset sequence", enter your reset sequence.
It's probably "123456789*0#", if not then try "3491672850*#".
Once the phone is connected to the tftp program you should be able to monitor what's going on in the "Log Viewer" tab.
Hopefully at this point you will see that phone transferring the firmware files.
It's possible that your phone is hard-coded to seek out only a specific IP address for its firmware files.
If this is the case, you should be able to determine the address your phone is looking for by downloading Wireshark (formerly known as Ethereal) and using the "Capture all" function. (You'll need to reboot the phone, but you can keep the physical setup the same.)
The DHCP requests will show the IP the phone is searching for; use that IP in your tftp settings.
If you're still having trouble, make sure that the phone is actually sending out DHCP requests (that should be recorded in the "Capture all" results). If it is not, the phone is dead and needs to be returned or scrapped.
Are you getting this error “Installer User Interface Mode Not Supported. The installer cannot run in this UI mode. To specify the interface mode, use the -i command-line option, followed by the UI mode identifier. The value UI mode identifiers...
The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
