Greetings!
Newbie here. A sister company discontinued the use of their Telenium IP which we still use, and gave us their IP 7024D (LIP-7000 series) phones. In the process of reconfiguring them to use them as remote phones, I managed to brick a few :\
The first one I successfully reconfigured, then noticed the firmware was different so I just _had_ to try out "remote upgrade". Yep. Pretty dumb move. The phone ended up in download mode unable to FTP the firmware. I figured that that would be recoverable when I brought the phone back into the office, because I could still get to the web interface (which had a form where you can upload firmware). Well. No such luck. I switched the phone to DHCP. Now it won't even get an IP address anymore (yes, we do have a working DHCP server). Loss 1.
I had brought a second phone to home (just in case it wouldn't work rightaway). Well. I was in the middle of reconfiguring IP settings and gateway when my wife asked to use the computer, so I set it aside. When she was done facebooking, and I tried to finish configuring the phone but it was locked up solid. No response. I powercycled it. Now, that previously working (but misconfigured) phone won't go past Initializing.......
Brick 2.
I tried a third one at work. In the middle of playing with it (reconfiguring IP, gateway, and mode) I have an incoming call, so I had to set my play 7024D aside. Well. Same thing. Frozen, and nothing but Initializing.... on powercycle.
Brick 3!
I was able to reconfigure the remaining phones and didn't brick any others, but I would really like to revive my freshly killed phones.
I don't have firmwares, and I'm not sure whether or not these are available to end users like us. I'm not beyond setting up a tftp server and spending some time tinkering. I had one open (because on one of them the horn switch didn't work most of the time) and noticed that there is a JTAG header. This is not super useful to me as I don't currently have a jtag cable, whatever required software to reflash, nor whatever firmware file I'd need, but it gave me some hope.
I put the board of the phone with the broken horn switch with one of my bricks and that one now works great, but I'm still left with a couple of paperweights that worked before.
Is there hope? A semi-secret combination of keypresses or a way to reflash over ethernet? The firmware on our phones appeared to be quite old. I now know that he firmware on our new phones is actually a bit more recent.
Any hints would be most welcome. And yes, you may laugh - I had it coming!
Best,
Peter.

Plug the phone in without the ip connection. Hit transfer to force it into quick start mode. Configure it, re-connect it then hit speaker to reboot.

Hello Derrick,
Thanks for the response.
No luck with that - transfer button seems to do nothing, at any stage of the boot process.
The phones stuck at INITIALIZING ... don't respond to any keypress, and the phone that I broke by trying firmware flash doesn't respond either. Eventually it times out with a message on the screen:
DHCP SVR - NO RESPONSE FAILED(3332858# ->DFLT)
