I also have the green solid state on the LED. Have tried to update the Photon with DFU, no errors there, When I hold down the SETUP and RESET button to try to do factory/ wifi reset and so on it starts to flash different colors. But when I release the SETUP button it always return to a solid green light direct.
Hi,
I am able to claim the device from within the Tinker app, but once completed the entire process, the device stays offline, rebooting results always in the solid green led.
You guys must know what the solid green means right? Could you please share that with your customers?
In case you donāt know, I really would like to see my device replaced with a working one.
@Hmbucker, The solid green led isnāt an expected condition, so itās not something we can tell our customers about. (Iād already mentioned that, in case you missed it.) I donāt think it means that your device is permanently broken, only that we need to take some steps to get it working.
Can you please try starting the device in safe mode and let me know how it behaves? Hang tight - weāll get this resolved! Thanks

@Hmbucker, I had exactly the same problem that you mention, thought that I calmed my new photon but it didnāt show up as online, got the auto update and then solid green lightā¦ Also tried the same things upgrade with dfu and so on, but nothing of it helped me. Always end up with the solid green ledā¦
But now seems to have manage to overtake the green problem. I thought that I had tried every button/ mode option that exist. But I accidently lost pressure on the SETUP button when pushing the SETUP and RESET. So Photon just started to flash magenta when I lost it, max 1 sec of magenta flash. After that LED started to flash green. Then I was able to put Photon in Soft-AP mode by holding down just the SETUP button, without the RESETā¦
@Martin, are you still having issues?
Hey @Hmbucker - Iād like to try to reproduce the problem youāre seeing on my photon. Could you please send me a full memory log of your photon? You do this by putting the photon in DFU mode and run this command:
dfu-util -d 2b04:d006 -a 0 -s 0x8000000:0x10000 -U memory.bin
With that, I will be able to hopefully reproduce the issue and work on investigating what causes it and a fix.
Also, please try Safe Mode and let me know if that resolves the issue for you.
Thanks
mat.

it seems to be solved for me 
Thanks for asking.

@mdma Hi Mat, I am also experiencing the exact same issue. Installed latest firmware, factory reset many timesā¦ every time I set up the Photon with the iOS app i get through the entire process, but the app says the device is offline and the LED is breathing magentaā¦ this is where Iām stuck. If I push a button or toggle power the LED goes to solid green. Iāve also tried safe mode. Here is a full memory log that you requested form @hmbucker above. Hope this helps.

Looks like one of the two photons Iāve received today has the same issueā¦ Initial setup via the app seemed OK, however after the setup was complete, the app stated that the photon was no longer connected to the cloud and Iām stuck with a solid green light.
Iāve reset it multiple times, I can enter dfu mode and have just flashed 0.4.3, the flash completed successfully but Iām still stuck with a green LED and a photon that I canāt do anything with.
Iāve tried to start it in safe mode but that doesnāt seem to work either, as soon as you let go of the setup button it goes green 
My other photon seems to be working fine so thatās a plus i guess !
Iām assuming that its not a F/W issue as its not affecting all photons? Iām going to email Particle now to find out what the options are for a replacement, just about counts as a DoA really as its unusable in its current state.
Hi @JohnM88 ā please try the same command that Mat mentions above:
dfu-util -d 2b04:d006 -a 0 -s 0x8000000:0x10000 -U memory.bin
And send that binary to me. 
In general Iām seeing a trend in this thread ā everyone should make sure to wait up to 60 seconds to see whether solid green gives way to some other state. Please tell us exactly what the LED was doing before solid green, what you did to trigger solid green, how long it was in solid green, and what it did after solid green. We need some very clear steps to reproduce if weāre going to debug this one quickly.
We saw this issue when entering listening mode and have fixed that I believe in 0.4.3. 
However a very similar issue has cropped up as a race condition in WICED that sometimes occurs when getting a DHCP lease. We hope to fix that one in August.
Thanks for all the help everyone!

Hi everybody, I had the same issue of youāre talking about. Solid Green light and Photon that doesnāt seem to be awake.
I tried all the āprescriptionsā I read above and around but with no luck.
So this was my procedure: I hold down the setup button for 10 seconds, after magenta/cyan blinking, yellow blinking and solid white the led become switched off for 1 second. Try to release the Setup button when the led is switched off.
The press the reset button and again the setup one. After this kind of challenge I had my blinking blue led. After that went on with the iOS app but I had to reload the tinker app in order to let the iPhone communicate with the photon (it was always āofflineā). I hope this can help.
Regards!
Holding the setup button alone won't do that. You're cycling through the modes, which only happens if you hold setup, then press reset (or plug it in while holding setup). After blinking solid white, it'll start the cycle again, starting with blinking magenta, indicating safe mode.
if you press the reset button first, and then the setup button, it will take you to listening mode at 4s (blinking blue), and erase credentials at 10s (blinking blue quickly). Having pressed the rest button before holding setup has absolutely no effect. You might as well not press reset.
That said, thanks for sharing, and I'm glad you got it working!
The one thing I noticed before mine went through the steps to update is the photon was getting really hot. I was able to get it to register and it went through the update process. After a long period say 10 minutes it went to solid green and has not been responsive since. It is also no longer hot to the touch.
In order how I remember the process.
Plugged in for the first time, solid blue.
UnPlugged plugged back in blinking blue, was getting hot
Registered with phone app, hot
Update process started, hot
10 minutes later solid green, cooled down
No longer responsive to button pushes or unplug and plug back in. Always solid greenā¦
Also have a single Photon from a batch of around 30 units used so far (ie 3% failure rate) that is in the SOLID GREEN state.
Same issues as described in prior posts: solid green, but can enter flashing yellow DFU mode. Looks to have successfully downloaded firmware 0.4.3.rc2, but made no difference.
Cycling through the modes to flashing white (factory reset), but release at this point just returns to solid green.
Memory dump here:
https://drive.google.com/file/d/0BzdAC5rcyb9kbVJaaGdrOVhxZ28/view?usp=sharing
I will set this unit aside and report back when new firmware is release to see if this overcomes the issue. Will also report back if any others exhibit the problem.
Upgraded system from 0.4.3.rc2 to 0.4.4.rc2. Unfortunately the issue remains.

Hi @UMD,
Thanks for posting your results! It sounds like this is happening to just one Photon in your batch, I wonder if the unit is defective? (Since itās staying in Solid Green after a factory reset and firmware upgrade). Iām guessing you donāt have a JTAG programmer handy to fully erase / reflash it to test, but if you wanted to email us at hello@particle.io, it might just be a unit we should RMA for you.
Thanks!
David
@Dave, thanks for advice. Would like to persist on the āself helpā track because if it can happen once, it can happen again! Asking for an RMA is the last resort.
Will go down the JTAG route and report back (could be some days).

Hello, Iām experiencing the same issue with one of me 2 new Photons. Is there any resolution to this thread?
We now have a binary dump of a photon that has this issue so we have something to investigate! Will report back with findings as they happen.
What is safe mode? The link (http://docs.particle.io/photon/modes/#selecting-various-modes-safe-mode) is not valid anymore.
