GG! You deserve a tip for your generous work. Ever considered getting a Ko-Fi? I'm sure someone will tip you for this.
Picofly (RP2040) OLED getting error Failed to init eMMC. But with HWFLY working fine.

I have the same issue with purple screen after installing picofly from Ali, and I understand that installing HWFLY solves the issue somehow, the problem is there are only INSTINCT clones are for sale now. Do they also solve the issue? Anyone had experience with it?

@PaulGr This is the solution, literally at the bottom of the previous page. You should read the thread next time.
I read the thread and saw this solution, but this is not what I asked. I asked about other solution with installing HWFLY.
I know that people swapped RP2040 with regular Hwfly and the purple screen went away, but v4/5 chip are so rare these day.

Ahhh, you want to fix a purple screen before trying the solution. I'm a little slow this morning, woke up an hour ago. Well, you could always try the Trading Area forum to try to acquire a HWfly from a member here. Other than that, there's eBay. Those are your best bets.

So you tested these values yourself with a multimeter? If so, then PicoFly must have put out a revision with a better resistor on board, but if you're saying that this results in a purple screen as well, then maybe that post wasn't the only solution, but a possible solution? To be sure, you are putting this in an OLED, correct? This issue only happens on an OLED with PicoFly 2040 for OLED installed. If this model is not designed for an OLED unit, or you are trying to install it in a Switch Lite, then that 238 ohm resistor will indeed cause a purple screen.
Yep, I tested the resistors with a multimeter and yes, that's an OLED model.
I've already modded 2 oled's with similar picofly boards and all worked fine. Now, the only thing that comes to mind is that those 2 oled's were 16.+ FW. And this one is 17.0.1

Uhhhh, yeah, that'll probably do it if AMS isn't the latest version and you don't disable blanking the serial in ProdInfo.Yep, I tested the resistors with a multimeter and yes, that's an OLED model.

Hi!, Rarely, but it happens, some models are not compatible with aliexpress chips. In all cases I solved it with rp2040-tiny and extra resistors in dat0 and sometimes also in cmd. Anyway, I don't remember getting a purple screen, I do remember partitions being deleted or a slow emmc.Yep, I tested the resistors with a multimeter and yes, that's an OLED model.

You might be on to something. Normally when people get this purple screen it means their user partition table vanished and the only way to retrieve it was using HWFLY.Ok, so the purple screen issue is solved!
Had to add 100 ohm resistor to DAT0, on top of the existing 240 ohm (total 340 ohm) and it worked perfect. Booting to OFW and CFW no problem.
Can't really say for sure but it seems like you found a solution to this "bricking" issue that people been facing forever.
Not sure if this is a solution for a vanished user partition table, but definitely a solution for this kind of purple screen.
My eMMC didn't init in hekate, I got "emmc init failure" error, while to see vanished user partition table, eMMC must at least pass init stage.
Btw, I modded 2 more oled's after that with the same picofly board, one was samsung eMMC and the other one hynix. Both worked fine. So yea, no clue what had happened, can't see any pattern.
If you want to help provide input to help others you could reproduce the problem (of course after doing backup and stuff).
This time you need to check your NAND table. I personally only seen this happen one time after modding hundreds of units.
According to this purple screen can mean several things one of course related to GPT table.

Yes, just placed it inline to picofly board. Replacing 238 ohm resistor can be done but there's a good chance to burn it..
Speaking of burned resistors, I recently had the same issue with purple screen on OLED model, and adding inline resistors didn't help, (tried to add to dat0, to cmd and both). Turns out replacing cmd resistor solves the issue
. Bottom line, this resistor was damaged during the soldering and it's a known issue to cause purple screen.Similar threads

Eventhough the New 3DS XL is more powerful, I still feel like the DS Lite was a more polished system. It's a real shame that it never got an XL variant keeping the GBA slot. You'd have to go on AliExpress and buy an ML shell to give a DS phat the unofficial "DS Lite" treatment, and that's the best we'll ever get I'm afraid.+1 -

@Jayro, I don't see whats so special about the DS ML, its just a DS lite in a phat shell. At least the phat model had louder speakers, whereas the lite has a much better screen.+1 -

They probably said "Hey, why not we combine the two together and make a 'new' DS to sell".

@SylverReZ if you could find a v5 DS ML you would have the best of both worlds since the v5 units had the same backlight brightness levels as the DS Lite unlockable with flashme -

A woman with no arms and no legs was sitting on a beach. A man comes along and the woman says, "I've never been hugged before." So the man feels bad and hugs her. She says "Well i've also never been kissed before." So he gives her a kiss on the cheek. She says "Well I've also never been fucked before." So the man picks her up, and throws her in the ocean and says "Now you're fucked."+1 -

anyways, we need to re-normalize physical media+1
if i didn't want my games to be permanent, then i'd rent them -

Agreed, that why I try to buy all my games on disc, Xbox anyways. Switch games (which I pirate tbh) don't matter much, I stay offline 24/7 anyways.

@BakerMan - you can still "own" digital media, arguably easier and better than physical since you can make copies and backups, as much as you like.
The issue is DRM -
@
cearp:
You can buy drm free games / music / ebooks, and if you keep backups of your data (like documents and family photos etc), then you shouldn't lose the game. but with a disk, your toddler could put it in the toaster and there goes your $60
