I now have two Photons that will no longer flash any (tried multiple different programs including blinky) new code from the web IDE over Wifi. The WEB IDE says the flash was successful and after the Photon resets normally, but the code on the Photon has not been changed. They will however flash corr…

I’ll have to make the notes clearer about which method doesn’t work for the bootloader, i.e., USB/DFU :slight_smile: You can only flash the bootloader OTA or YModem over USB. Try this, put your Photon in Listening Mode and run: particle flash --serial bootloader-0.6.2-photon.bin

What system version have you got installed on your device? I had troubles after testing 0.7.0-rc.2.

I did have 0.7.0-rc.2 on for a while but reverted back to 0.6.2.

That might well be the reason. Downgrading to 0.6.2 from 0.7.0-rc.2 requires youto downgrade the bootloader too - see release notes Particle Device OS Updates Thread - #48 by BDub

I guess I should have read the fine print.

Where do I get the 0.6.2 bootloader binary? I do not see it at the link you provided [image] Particle Device OS Updates Thread Particle Updates Firmware 0.7.0-rc.2 Pre-release is out on the Web IDE for Core/Photon/P1/Electron released on production servers July 14th, 2017…

I flashed over USB system-part2 -> bootloader (v0.6.2) -> system-part1 and it still does not accept new programs over the WEB IDE. New programs load correctly using CLI and DFU.

@tjtrolinger Could you put your device in Listening Mode and run particle serial inspect and paste the data here? You’ll want to see v11 bootloader, and v108 for system parts if you have successfully downgraded to 0.6.2.

Thanks for the reply The bootloader is version 100. How do I get it to V11? Thanks, TJ Platform: 6 - Photon Modules Bootloader module #0 - version 100, main location, 16384 bytes max size Integrity: PASS Address Range: PASS Platform: PASS Dependencies: PASS System module #1 - version 108,…

That WORKED! I can now flash again from the WEB IDE. Thank You for your help. TJ
