Verizon Onetalk Yealink Phone Migration

This is a working draft of solutions taken from the Internet. Information from this post: https://www.reddit.com/r/3CX/comments/11zmfm8/converting_a_verizon_onetalk_t57w_to_use_with_3cx/

OPTION A:

Open a Yealink ticket for the device you would like to reset. In the ticket let Yealink know the device is not starting up, they will send you a link to get the recovery mode firmware for that specific device. You may also find the recovery firmware in the "Recovery Mode Link Procedure:" below.

The zip will have 2 files in it. Extract those to a FAT32 USB. Then put the USB in the back of the phone. Turn on the phone will holding the redial key (speaker key may work here as well?), and then select USB.

The device may not do RPS, since (I think) that MAC is not considered a Yealink in the RPS system.

Notes from Forum post:

So for anyone coming in here in the future with this same problem...Here is what worked for me. I have several Verizon OneTalk T54W desk phones and wanted them on generic firmware.

It is running Verizon Firmware 96.85.21.15.

Let's start with what didn't work:

• Using ROM files from other sites such as google drive

• Using 3 files on a FAT32 USB stick

• TFTP using 3 files

• Factory resetting in recovery mode, enabling the web interface, and trying to "upgrade" the firmware to generic.

So what did work:

1. Go to this yealink support article https://support.yealink.com/en/portal/knowledge/show?id=612b5fcd8c4dcd0723922195 and download the NEW RM.zip file on the page. Extract the files and rename them to match your phone. T54W.rom and T54W.bin

2. Following the RM guide link within that support article, create a TFTP server and place the two files BIN and ROM into the working directory. Set your IP address as described below.

3. Plug your phone directly into your PC's ethernet port and set your static IP within windows settings to one off what the phone will be. Example windows settings:

• 192. 168. 8. 80

• 255.255.255.0

• 192. 168. 8. 1

1. Plug in the phone using the power adapter and hold the "redial" key immediately. This is the double arrows in a circle that almost looks like a repeat button.

2. A blue screen will appear on the phone. Select 1 for TFTP and then enter your IP address details. Example below:

• 192. 168. 8. 81

• 255.255.255.0

• 192.168.8. 1

• 192. 168. 8. 80

1. Hit the OK button, and it should start to flash the firmware.

- If you get an error here, it is likely because your Verizon firmware is incompatible with the firmware you are trying to flash. If you are on the version I described above, make sure you are using the NEW RM files, and only a .BIN and .ROM.

- If this is a super old phone and it hasn't seen an internet connection in a while, connect it to the internet and let the Verizon firmware update first. Retry the steps above once it has been updated.

I hope this helps someone and saves the several hours I spent digging and trying to get this to work.
