Purple/pink screen OLED after HWFLY install

[Ganesha0112]

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

 

[Ganesha0112]

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.

hi,hope the solution works for me,i install in a brand new oled console this chip,4-5 times console start without problem,but next time get black screen and then after open the console chip only get blue light and no more start in hetake,now i get purple screen,my tech guy will change the resistor you say,really hope works because is a brand new console

It point to the emmc.

to the resistor than everybody say in the post ??, see this video,exact problem,oled with chip,purple screen,guy change the resistor and works, in our case console works 4-5 times,after that get only black screen trying to boot,then we remove the chip and get the purple screen,look


update:we change the resistor and now console dont turn on at all :-(

what’s the problem, what the console do now?

we install this version chip,console boot perfect fine 5 times,after that get fuse error from atmosphere,then drop dead,now only dont turn on and show 2 times purple screen,we remove the chip,clean all poits,change the resistor,and nothing happen,is a brand new oled :-(

The console won’t turn on after the resistor was changed? Or the purple screen is still there?

After having the error in hetake, we opened the console, without removing a single screw, only the back cover was in hetake and the screen froze, at that point the chip stayed in solid blue and from that moment only screen black, we removed the chip, we cleaned all the points, we changed the resistance and nothing, after 5 hours we connected the battery but only on 2 occasions it gave us a purple screen,now only black screen :-(

NOTE:Now I have seen 3 videos on this sthetix youtube channel, there are 3 brick levels, even the option to use a donated nand (yes i know never read cartridges again) but at least it is an option to be able to use atmosphere, BUT the console doesn't turn on at all. We don't know what else to do.

Check everything, or reconnect the chip, if the console it’s alive the chip will be run. If it run make a EMMC test. If the chip blinks purple check if there are a bridged point, check the CLK point it’s not missing or something

Today we are going to try to turn the console on without a chip, at this moment it does not turn on, it just stays black, if we can at least get it to turn on, we reinstall the chip, now if it receives voltage in the processor and the nand I mean voltage goes in and out, the technician already measured values, but we still don't know why it doesn't turn on, as I was saying if the chip corrupted the nand but at least you can use the donated nand technique at least it's something... today We are going to review in more detail with microscopes and other tools, we have installed several hwfly without any problem, the technician has experience, and we do not understand how the machine worked 5 times, after nothing else it died.

Re install the chip and check if it turn on. Picofly turns on even if the nand it’s corrupted, technically your console turn on with the damaged resistor, or check the screen conector

Some days before I got a Nintendo switch that don’t turn on without a picofly installed, like the console was dead, the voltage values don’t show like the switch have a short but look like the processor don’t consume energy. I re install a picofly and the console turn on and even can get to OFW. Just try it if you don see anything bad in the motherboard like a bridged points

well right we looking for a oled mainboard diagrams for can test all the values,but no luck yet,we want first try to start the console clean without the chip,but if no luck then try with the chip

Did you manage to solve the issue? I got purple screen too, then just resolder cmd and it worked partially. I can't boot to OFW,, but managed to copy create emummc anyway. So cfw works. OFW just black screen.

Change it for a new one. The common problem is that the resistor burn and die, actually my problem with the console it’s the resistor die, cause I re install the original resistor and the console still no works and it works when I reinstall a new one, then few months on another console Installing a picofly the resistor burns and hekate works, actually i can make a EMUNAND. But when I try enter to OFW purple screen is still there, so I install a new resistor and everything goes perfect

error.

Soo I also have bricked my switch oled with purple screen wenn booting in ofw. I tested CMD resistance desolderd from the motherboard, 4.7k. I can boot into hekate and run Emunand without problems. Nand issue? I tried stethix first video to unbrick the nsw but no luck. I'll try the second one

Did you solve it? I have the same problem. I have installed the chip, I created the emunand, and start to install Games. I tried to start OFW but stuck in black screen after 2 second of Nintendo logo. Now I am getting purple screen only if I try to start in OFW, CFW works fine. Do you know what could it be?

As the picofly guide on this forum tells you to, if you cant boot ofw then change cmd and DAT0 resistors on the modchip to 100ohm.
In the guide they show you picofly boards but the same goes for the hwfly pico boards.

You can look here wich ones to change:
https://gbatemp.net/threads/hwfly-shaped-picofly-boards-start-shipping-in-china.632179/page-8

Post 158 in that page, i have done it on several hwfly boards that could’t boot ofw without changing resistors.

Edit: I always change those resistors before installing the modchips nowdays.
