During development with the Spark Cores, I would first claim and flash them at home, to ensure everything worked. Then I’d take them to where I wanted to deploy them, factory reset them ( hold both buttons, release the rightmost button, wait until fast flashing white, release ), reclaim them, and fl…

Hi @Quentin I suggest you read this thread [image] AVOID factory reset - What to do with unexpected LED behavior on a Photon Hey everyone! TL;DR - If in doubt use Safe Mode rather than a factory reset to avoid potentially bricking your device. Just wanted to bring t…

Thanks @bko . I saw that yesterday, but only after trying the factory resets. However, my Photons were on 0.4.4 before factory reset - so at least I don’t think they’re damaged, and it looked like I was able to get them back after some effort. The goal of the factory reset was just to be able to clai…

[image] Quentin: Still, having a functional factory reset would be great ! I agree and it certainly should work and bugs should be reported (likely on github). But the design of Photon was such that "safe" mode was considered to be what you needed 99% of the time so you can reflash you devic…

Understood. I’ll do a little more diagnosis before opening an issue on Github, I’d like the full error messages. I’ll try particle setup wifi first, then Safe Mode if that doesn’t get me what I want. Thanks, @bko .

[image] Quentin: that was one of the easier ways to connect the Cores to a different network You could use listening mode, which is what it's made for. If you want to clear all credentials, simply hold the setup button, until it starts blinking blue quickly.

Factory reset on the photon will get some love. I don’t think it will ever function like it does on the core, since there isn’t room on the Photon for a separate copy of factory firmware, and right now it’s not clear to me what it should do. So a future update may simply drop factory reset altogethe…

@Moors7 : I’ll try that tonight, thanks. @mdma : dropping it might be a good idea, then. Point aside, is there a simple way to flash the factory firmware, assuming the Photon is claimed and on the cloud ?

You can use dfu to flash the binary to address 0x80E0000. Please note that this will be overwritten next time system firmware is updated.

Why exactly would you like to get the factory firmware back on it? Anything specific you like about that?

I liked the “pull out my phone and claim it in seconds” aspect, rather than having to pull out a laptop and squeeze USB cables into my prototype. Also, when I first tried claiming these Photons, it wouldn’t work via the Particle CLI. After failing a few times, I tried the Android app and it was quic…

Factory reset not working

Not exiting listening mode is a bug announced in the release thread. A fix is already in place, to be released next week. For now, just hit reset after providing credentials, or you can apply the workaround mentioned in the issue description.
