Photon has been working fine for months, suddenly stopped working. Goes into RED SOS Hard fault mode. Here is what I have tried so far.
ENTERING SAFE MODE - Tried entering safe mode, holding down both buttons, releasing on magenta. Instead of breathing purple, it simply breathes white for a bit and then goes back to RED SOS.
UPDATING FIRMWARE - I am able to enter DFU mode, so I tried $ particle update. It said the update was successful but the problem was not fixed.
FACTORY RESET - Tried getting to the factory reset option, but the LED flashing cycle never gets past yellow flash. As in, I hold down both buttons, release reset, it flashes magenta, then flashes yellow, then... keeps flashing yellow.
DOWNGRADING FIRMWARE - Downloaded an old version of the firmware, reverse flashed it (part 2 first, then part 1). Terminal said it was successful, however it doesn't fix the problem.
Any ideas? Here is a link to the SOS.bin file (dfu-util -d 2b04:d006 -a 0 -s 0x8000000:0x100000 -U SOS.bin)
