Hi,

I've purchased a Deco M4 single unit in March 2020. The unit uses lower 5Ghz channels but in my country here we need 150+ channels for 5Ghz support. After setup, none of my devices find the 5Ghz network. So I've contacted Tp-Link Bangladesh and they gave me a customized/modified firmware which is "1.4.1 Build 20200721 Rel. 24433"

Now today I've purchased another Deco M4 single unit & it has "1.4.1 Build 20200714 Rel. 47859" firmware. This firmware seems working fine with the 5Ghz band. So I search Google for this firmware but can't found it. So I've contacted Tp-Link Bangladesh for this firmware and they said from now the newer shipment Deco M4 units are ready for Bangladesh and they uses 150+ channels by default. But they said they don't have the newer deco unit's firmware that is ready for Bangladesh. I'm contacting here because I want the newer firmware "1.4.1 Build 20200714 Rel. 47859" that comes with new Deco M4 units. So that I can install this firmware to my old Deco M4 unit. Please give me this new firmware.

Note: Both my new & old Deco M4 units are V2 [US]. I've attached a screenshot for better understanding.
