Actually it isn’t anymore. I am sure that somewhere hidden deep inside the tubes one may find the solution (not me), I didn’t feel like wasting that much time – instead I just called Grandstream.

If you are suffering the loss of a beloved GXP as well, do not fret – geekhut has the fix!

What you need :

• A router that is not currently serving you data (I used m0n0wall on an old p3) <= we will discuss that later.
• Firmware
• Sailor hat, for absolutely no reason

Procedure

1. Plug your router in as you normally would, internet access is not needed at this time.
2. Plug your phone into any one of the LAN ports
3. Configure your router’s IP to : 168.75.215.1, Subnet : 255.255.255.0
4. Plug a computer into the LAN port of the Phone (it didn’t seem to work for some reason when I plugged it into the switch…)
5. Install a TFTP server on that computer, Windows sure has a lot of shitty ones – instead I temporarily loaded my tftp.plist (I think i used -f) on my Mac.
6. Unzip the Firmware you downloaded earlier into your tftpboot directory, Leopard is funky and puts it under /private/tftpboot.
7. Statically set your Computer (the one plugged in behind the phone with TFTPD) to IP : 168.75.215.188 (same subnet as above.)
8. Cross your fingers, power cycle your phone – read the screen carefully.

* Things are strong because they matter.

I hope you now have a working phone again, you can send your love in comments.
