Firmware

Whatever i do with my photon, its coming back to safe mode blinking magneto.
At first i had a RED blinking SOS, bad hardware code. Then i followed instruction and some how got to safe mode, But after entering to safe mode ( magneto blink ), i tried to setup my photon in Particle app, everything gone well and it showed your photon is successfully setup. RGB was flashing cyan, but suddenly RGB started flashing Magneto. I tried DFU doctor mode. but my doctor is unsuccessful when i chosen Internal antenna. Please help me to sole this issue...

When the device suddenly starts flashing magenta this might indicate an incompatible Device OS and the Safe Mode Healer trying to cure that.
If it doesn’t succeede (may take a while and a few automatic resets), you could use CLI to repair that.

Make sure you have the most recent version CLI (currently 1.34.0) and then run these commands in DFU Mode (blinking yellow)

particel flash --usb tinker
particle update

After that you should have 0.7.0 Device OS on your device. To make sure that worked, put your device in Listening Mode (blinking blue) and run

particle serial inspect

(you may need to add --port dev/tty.... to select the correct port)
Once you have the inspect output you can post it here.

You have a bootloader issue. System modules v207 require a bootloader v100+ but you have v4
Since particle update didn’t cure that you need to download this and flash it via Listening Mode

particle flash --serial bootloader-0.7.0-photon.bin

I have removed you double post, since it’s just a copy of the previous one.

Can now repeat the particle serial inspect and post the result?

If the device keeps blinking green and doesn’t proceede further it can’t connect to your WiFi network.
You need to clear the WiFi credentials by holding SETUP 10+ seconds till you see rapid blue flashing.
After that enter your credentials again via particle serial wifi
