Title: Reflashing MiNet Firmware to 6900 phone
Post by: bigyorkshire on October 15, 2018, 08:15:26 AM

Hi all,

In order to get a 6900 series phone to work on the MiVO 250 or 400 systems, they have to be flashed with SIP firmware - no problem.

However I've been given a phone which has been flashed with the SIP firmware and need to get this back working on a MiVoice Business.

Has anyone re-flashed these back to MiNet and got any idea where to start?  :D

I believe you can just upload the MiNet firmware from the Phones WebUI.

They are stored on the MCD (under the TFTP dir) and called:
MINET_6920-enc.st
MINET_6930-enc.st
MINET_6940-enc.st

Can it be done the opposite way? The 69xx phones with the SIP firmware support Czech language however the phones with MiNet firmware do not.

I can confirm this worked. FTP's the firmware files down from the MiVB controller to my laptop. Ran tftpd and pointed the phone to my laptop using the web admin interface, flashed back to MiNet :)

bigyorkshire or anyone

Can you go into more detail as how you got to ftp the firmware files

Did you use the FileZilla software and ftp to the Ip address of the Mi Voice Business using the systems username and password?

what was your port number

or if you can the path to the 6930.st file

And what app did you use for tftp

Thanks in advance

most would use tftp32 or tftp64 and host the files on a local Windows machine.

as others have mentioned, tftdp32 or tftpd64 is a great tool. There is also Pumpkin but it is purely for tftp and sometimes fails with large transfers.
