WB2S Module Not Connecting to WiFi After Flashing with BK7231 Easy UART Flasher

Using the latest BK7231 Easy UART Flasher, I'm able to backup and flash the WB2S module out of the Martin Jerry US-SS01 single pole switches I have. However after it's done, I can't see any AP from the module, and it won't connect to my router. I've tried powering off/on 5 times, and I tried entering my SSIS/pass in the OBK settings for flash write. Realterm shows only zeros (hex) when I power on, though the USB UART adapter is only connected through tx1 and rx1 (I see mention of tx2, but my module doesn't have a terminal for that.) I wasn't able to get it to get bus by powering off/on or grounding cen, but it finally worked when I checked box 31 (Enable UART command line) in the OBK config before attempting backup/flash.

The initial backup I took shows below in the flasher tool. Can't recall if I connected this device to Tuya before flashing or not.

Device configuration, as extracted from Tuya:
- Button (channel 1) on P10
- LED (channel 1) on P26
- WiFi LED on P24
- Relay (channel 1) on P8
Device seems to be using WB2S module, which is using BK7231T.
And the Tuya section starts, as usual, at 2023424
