Deta Grid Connect Lights dead with vtrust-recovery SSID after flash

Hi, the other day I was flashing 2 [grid connect](https://www.bunnings.com.au/deta-grid-connect-smart-18w-1900lm-daylight-t8-tube_p0111511) lights with Tasmota. The process went well for one of the lights (though I _did_ have to configure tasmota), but the other will now not turn on, and it's SSID is vtrust-recovery. When I connect to the network, it disappears. I have seen people with the same issue, that say to ./start_flash.sh and then turn it on, but this does not work. It starts backing up the firmware but the transfer speed drops and then stops entirely.
Thank you

Start with ./start_flash.sh and the vtrust-recovery flow, then reproduce the firmware-backup transfer stopping after the device joins the recovery SSID. The issue does not name a source file or test; done would require identifying a reproducible cause and documenting or fixing the recovery-flash failure.
