T58A SIP to Teams firmware then back to SIP, Failed
Hi Team, I Need help.

I have a T58A with SIP rom that I flashed to the Teams rom for testing, no problem every thing worked.

I am done with testing and want to go back to SIP firmware however phone is rejecting firmware even via TFTP/USB flash.

I have then attempted to use TFTP recovery files, That I have from my distributor the .bin and .rfs files along with the rom, but this also fails.

I presume the fail is because the phone thinks the firmware is too large. the TFTP response from peer (being the phone) is "file too large" and rejects it, it will download the .bin and .rfs files no problem.

Hi Scottie,
This is Walter from Yealink Team. Nice to work with you.

We have made some restrictions on the downgrading of SFB to SIP Phone. You need to import sip license before downgrading. Can you provide the MAC of your phone and your Email address? We will apply for a license for you
Any update, please feel free to let me know.

Best Regards
Walter
