BK7231N USB Smart Switch Factory Reset Without Firmware Flash After SSID Change

Hi freaks,
I just playing around with my new USB Smart switch.
I configured the long name to a very special one.
I delete the main SSID and password and reboot.
After this the device was not longer reachable.
Cause the long name would be taken as the SSID name for the access point. And this SSID would not be propagate. See attachment.
So if there any way to reset the device to the naked new without flashing the firmware again?

I give the attachment with the boot messages on tx2 from the device:

Which name did you set, exactly?

Well, safe mode will attempt to open AP with the name same as set by user.... it seems that you've found a way to brick device beyond safe mode recovery. I didn't expect that.

Now you need to connect UART and use BK7231 Easy UI Flasher to at least change OBK name with Read/Write OBK config tool...

Hi,

http://192.168.4.1/usb_smart_swit

Was the exact Name I gave to Long/full Name.

Yes, I only got back access to the device after deleted this Name with read/write OBK config tool in BK Flasher.
