Hey, when I try to arm my quad it just beeps "di dut", the FC LED is constant (no more blinking) O3 loses OSD after some seconds and it no longer connects to betaflight configurator. When I reconnect battery it connects fine to configurator, MSP is the only disarm flag and I can spin up the motors.
Any idea what is wrong here? Is it dead?

Are all the cables connected
Yes, I also tried another 6pin O3 cable and also without O3 connected, same issue. It's an AOS 3.5 with Foxeer V4 AIO, O3, ELRS receiver and Beeper
It did flew for like 40 batteries, sometimes it didn't show OSD but was always fixed after reconnecting battery, then it permanently lost OSD, then didn't connect to configurator until I reflashed via bootloader
O3 doesn't seem to show the battery voltage in its own OSD, but everything else works?

Did it stop working after a crash or hard landing?

Did it stop working after a crash or hard landing?
Oh didnt get notification... no, no crash, it randomly didn't show OSD before and then after 3 normal flights one day it just stayed that way even with reconnecting different batteries 10+ times

Hmm, to be honestly I’m not really sure what the problem is

FC LED is constant... are you sure it's the FC LED? It could be the power LED.
My guess is that your 5V regulator is dead, basically meaning your FC can't be powered from the battery.
When you plug it into BF, that's when the FC draws power from BF, and it should die when unplugged.
If that is not the case, and the FC LED is actually solid (so there are two solid LEDs lit up on your board) there could be some funky bootloader stuff going on. Would be beyond me.
See if the bootloader button is damaged or the pad is shorted.
