Purple/pink screen OLED after HWFLY install

Hmm! Yeah I would probably replace it then as already suggested! Verified it’s soldered properly at a minimum. Either way I’m glad it’s turning on now.

FYI, when testing in diode mode the multimeter would not show a “k” value. It’s testing a voltage drop to ground so it should show voltage. Around .550 V to .800 V. You must have been in resistance mode still. Also you test with red prob on ground

Thanks everyone 4 your help. Yeah, the problem was the resistance, that makes me feel calmer. I sent to buy some resistances with the 4.7k value. Tomorrow that they comes I’ll remplace it. I really was scared that the problem was the emmc but still turn on normally with that resistance

Well, the problem was the CMD resistance, I fixed it making a bridge with a 4.7k resistance cause it was more bigger than the motherboard connections, yes I know it’s the most anti aesthetic thing but it works, and yes, the HWFLY works too making a bridge to the 4.7K resistor to the A point, I decide to change for a lite HWFLY and curiously that chip comes with SX software.

Thank everyone, the most common cause for purple/pink screen on OLED switch it’s the CMD resistance

Does the Switch boot into OFW with disabled chip (if you desolder +3.3V wire)? If so, reconnect the +3.3V cable, connect the chip via USB adapter to use PC, log into the chip through SSH program (Putty or similar) by connecting to the same COM port that your chip is detected by the PC. Run reset command by pressing "R" and later run diagnostics ("D"). This should give you some output of the chip behavior.

Does the chip has stock FW or did you update it?

Thanks for this. I got a purple screen with PicoFly on RP PICO. I removed it and now it boots to OFW. I'll never use RP PICO ever again. I'm all in for the tiny blue guy.
