Hello Yealink Support,
I actually have to update the FW of a total of 250 of W52H and with the W52P-flasher, updating 1 by 1 it takes me too long.
Is there any way to Update the FW of Various W52H at ther same time?
Thanks in advance
hi ,
Yealink W52P suppot OTA , in this case, you can use auto provision feature to upgrade the handset version.
OTA upgrade capability is restricted to specific firmware versions and handset hardware
1) Handset with firmware or later
2) Base station with firmware or later
3) Handset with hardware or later
OTA is only available when meeting the above three conditions simultaneously.

for more details, please refer to below guide.
Best Regards!
