Can't get to cloud after flashing firmware (particle update)

Troubleshooting
1

Hi,

First, i run

dfu-util -d 2b04:d006 -a 0 -s 0x8020000 -D reset.bin

to reset the photon. After that the photon can connect to cloud easily, but when i check with

particle serial identify

it didn't return firmware version. I assume that the reset.bin remove the firmware. So i run,

particle flash --usb tinker
partcle update
particle flash --usb tinker
particle keys server
particle keys doctor MyID

but it make the photon cant connect to cloud.. it just fast blinking CYAN and then short blink ORANGE and also short blink GREEN and back to CYAN all time..

what is actually should i do?

The most important info I was looking for was the bootloader version 101 and your system versoin(s) 207 which seem to be OK.

I'd not recommend resetting your device back to 0.4.1, but since inspect didn't revealy any issue, I guess it's fine.

However, I'd just repeat my suggestion from the other thread

and even if your other devices have no issue connecting to the same network, just try it anyway. And to be sure, I'd also recommend to wipe any stored credentials from the device by holding the SETUP button for 10+ seconds till the RGB LED starts flashing blue rapidly and then apply only the credentials of the new (non-WEP) WiFi network.
