Bug RE: V84.0.140, downgrade no longer possible?
We just attempted to perform a TFTP recovery on a T23G on 44.84.0.140 and it is also failing. Unfortunately in our current situation for this phone, this has led to it being bricked, it's now in the trash.

Yealink current v85 firmwares are broken, and Yealink frequently breaks things when they upgrade to newer firmwares that necessitates downgrades. Now testing later firmwares isn't possible since if bugs are discovered, there is no rollback.

DO NOT UPGRADE TO V84.0.140, DOWNGRADE IS IMPOSSIBLE IF NECESSARY

Sorry Yealink, it's been nice working with you. After >2000 endpoints deployed, I think it's time to pursue other vendor options...
