Installed brand new pan cam with 22.214.171.124 firmware, camera worked but upgrade to 126.96.36.199 failed, and now solid yellow light, tried both factory reset as well as power on/off and does not work at all.
Just to clarify, you said power on/off and factory reset. To be sure we are on the same page, are these what you did?:
If so, you might have to manually flash to an earlier firmware. Info here:
How to Find Firmware
Yes I guess, gotta find a micro sd card, thanks
