Purple/pink screen OLED after HWFLY install

[Jagovi]

@rull_bull

I have done the resistor change, my chip is the called “new oled” in the message that you said to me, but I got purple screen when boot OFC. CFW works fine. I have been reading about it but I can’t solve it. If I go to console info -> eMMC i get the image message.


In HW &Fuses I get the fuses of image.
Any idea?

Thanks!!!

Hello everyone, I install a HWFLY v4 on my switch oled and I’m sure than everything it’s soldered correctly, but when I finish the installation and turns on the switch the HWFLY led blinks on purple some minutes and then blinks red fast and then the screen of the switch turns purple/pink and starts turning on and off I don’t know what this happen but anyone know what I can do to resolve this problem?

I've experienced this, the solution at that time was, replace the SD card with a new one by installing a new atmosphere, hopefully it can help

I installed the chip on my OLED Switch. Everything went smoothly (I've installed over 50 on OLEDs). When I turned it on, it asked for the SD card, so I shut down the console. I put the files on the SD card and launched Hekate, created my EmuNAND, and started it. I installed a game and then opened Tinfoil, but I got an SSL error related to the time. I launched a couple of apps to try to sync the time. I tried starting in OFW to see if there was a conflict with the time set in OFW, but noticed it wouldn't boot. I've changed the resistors on the chip at points A and C to 100 ohms, but it's still the same. Initially, I got a black screen after the Nintendo logo, now it's just a purple screen. CFW still boots and works fine.

Your emmc is corrupt, if you have the complete backup and all the keys you could restore the emmc

@rull_bull I don’t have it. It possible any solutions? Or I have only a console with CFW.

You can mount your emuMMC to dump your prodinfo or just use tegra explorer, from there you can start rebuilding your sysNAND

Could you say to me the process? Thanks

I am facing the exact issue like as you. Did you come up with a solution? I am perfectly fine with emunand but when i selecting to boot ofw it goes purple screen. I haven't change the resistor yet.

You can test the resistor while still on the board with a multimeter. Only change if it reads out of spec.

So if it can help guys I can confirm that purple screen after a modchip install is (for my case) the cmd line, I can confirm too because I fuckedb up one side of the resistor, but thanks god not the trace, at first I not seen it but the weird lecture of the multimeter made me to change it , I had some weird measure, so it made me change the resistor and everything is ok now ...so i not saying it the absolute true, but yeah my purple screen was due to bad cmd resistor command....
I changed the resistor of 4,7khom , and everything is alllright now

ps: you have to be very relaxed lol, it's 201 size resistors, have tiny pencil tooo
so , not everybody can do this, be carefull, I have experience in modding etc but really, nintendo switch is The thing ^^ , if you not have a microscope you are fucked up ^^

It's just simple I think Switch modding gave me all the experience of tiny soldering ^^ , (before I was thinking dreamcast HD modding was hard ^^ ) huhhu, now it's finger in the nooose ^^, as I modded now maybe 30 console , oled lite v1 v2 , ^^

But so yeah, with experience you can do it all (y)

I'm having a pink screen issue as well. I can boot to hekate, but I get the EMMC init failures, and when trying to boot OFW I get the pink screen.

I am thinking it is the 4.7k resistor that somehow got burned while soldering. I tried testing the A point with the diode mode on the multimeter and I get around 0.45 (not 0.55-0.8 like others said). Is it likely to be a broken resistor? Is there anything else I can check? I tried testing the resistance on it with a multimeter and I'm not getting the right readings (that said my multimeter is quite large and it's hard to get accurate readings on such a small component).

Purple screen on a modded Oled is almost certainly the CMD resistor. The value should be 4.7k. It looks like they used 30awg which is way too thick, likely broke the resistor terminal. swap those wires for 36awg. the clk via under the heatspreader is also very brittle and the most difficult point. If they used 30awg there it's likely been ripped.

Hi everyone, hope is ok if I post here to don’t open a new thread.. I have a similar purple screen issue after a fail install of picofly, I removed all the flex cables.
IMG_9051, I had to replace this caps (red and purple circle) 0603 22uf and 0201 470nf, please correct me if I’m wrong.
I ordered the caps from Aliexpress, in IMG_9041 you can see the measurement of the 0603 cap and it shows only 14.5uf instead of 22uf and for 0201 only 370nf instead of 470nf, am I measuring wrong?
Contacted the seller (IMG_9063) and I don’t know what to belive.
In the left side of 0201 cap is a component which I burned a bit with the soldering iron till I found out I should buy a heat gun for this tiny work, I don’t know if it can cause a purple screen but if you know what it is I will replace it just to be sure.
IMG_9053 and ..54 are caps from CPU and in IMG_9052 are resistors with 4,69k and 46,9k measuring, should I replace any of this ?
Thank you!

Edit:
I fixed it.. looks like caps are ok, I think I need a better multimeter.
Used hot air gun on the cmd resistor and purple screen was gone, tried to mode it but purple screen appeared again, replaced 4.7k resistor and now everything is ok.
I finally modded my first Nintendo console.
