Flashing ExpressLRS Backpack 1.3.0 to HappyModel EP82 "Update error: ERROR[4]: Not Enough Space"

[slash128v6]

I have an ImmersionRC Rapidfire analog module with a HappyModel EP82 VRX backpack. Building the 1.3.0 backpack firmware using ExpressLRS configurator 1.6.0 for VRX target HappyModel EP82 VRX Rapidfire Backpack for WiFi flash method results in file "Rapidfire_HappyModel_EP82_VRX_Backpack-1.3.0.bin". When attempting to flash this to the EP82 via WiFi I get "Update error: ERROR[4]: Not Enough Space".

I was able to work around this by flashing 1.2.0 first. But I had to use PlatformIO and VSCode to build because the hdzero.ini file had dots (.) in the env name which caused ExpressLRS configurator to throw errors. After building I flashed 1.2.0 to the EP82 and then was able to build and flash 1.3.0 to the EP82.

had same issue with flashing 1.4.1. needed to reflash to be sure, what is the binding phrase. Flashing 1.3.0 and than 1.4.1 back helped
