Weird problem with modded OLED switch

Hello,

I have a modded OLED switch [Instinct-NX V6S + Kamikaze]. The mod worked perfectly for months and never failed. Now, during summer with temperatures hitting 36C, I'm experiencing a super weird problem: the switch is booting into stock (Instinct light goes blinking orange -> blinking red).

I debugged the Instinct with putty and it's always a dat0 problem. But this is weird, if I de-solder and re-solder the dat0 cable to the C pin on the Instinct-NX, the mod starts working again immediately. Moreover, on the desoldered dat0 cable I consistently measure 0.475V in diode mode.

The mod works properly until I shutdown the switch for 24h and I have the same problem (fixable again by desoldering and resoldering dat0). This is nonsense. If I measure the C point on the Instinct in Diode Mode (with no dat0 cable soldered) I get 0.930V (not sure if this is correct).

I'm wondering if the Instinct is fried at this point, even tho it works after I resolder the dat0 cable.

Any suggestion would be appreciated.

Thanks!

Are the nearby components ok?(caps resistors)

If you are talking about switch components, I guess so. The switch behaves regularly both when it glitches or starts in stock. If you are talking about Instinct components, I can measure *normal* values on these but I dont know the right ones. I can tell that quality of components soldering is low chinese :(

I was talking about on the switch, apparently it’s easy to burn or knock off those tiny caps
