Can't connect to the device anymore

I have tried to flash a Sonoff Basic through OTA when something went wrong. First I have flashed the minimal image, which was successful. After that, I tried to continue the process by flashing the normal image using the same method, but after the reboot the LED blinked at 1/s rate

Since I couldn't connect to the device using wifi anymore, I've used esptool to erase and rewrite the flash with the precompiled sonoff.bin and sonoff-classic.bin from the GitHub releases section (v6.2.1). Neither did help. Two other devices (an S20 and a POW) flashed perfectly using the OTA method using the same images.

As a hail mary I've reflashed with the serial converter to v6.1.1 and now it's working again. I don't know how to get debug data since I was cut off from the device completely on v6.2.1

Hi

Sonoff.bin v6.2.1, from release had a compilation issue. Please try to download it again or use the precompiled bins from http://thehackbox.org/tasmota/

Thanks
