Solved Yealink T53 Failing to Update from 96.86.0.70

[FinlandTechnology]

I was running into an issue upgrading a bunch of refurbished yealink T53's that were on 96.86.0.70. Kept trying to install 96.87.0.15 to get to 96.87.0.15

Resolution was here: https://support.yealink.com/en/portal/knowledge/show?id=67ea8ab413440e4c2e145270

Interim version 96.86.0.118

Figured this would be helpful for anyone running into the same issue!
