Hacking Hardware Picofly - a HWFLY switch modchip

[Stonehearth]

What version is the firmware?

2.74 on picofly

18.1.0 on ofw and CFW up to date everything and checked after modding correct more than 100 units

Resistor values? Which modchip? I had that same error once, and the cause was too much resistance on the CLK line (47ohm + the modchip had another 47ohm on board already).

I put 100ohm resistors in each spot. I could have sworn that’s what I was doing before (it’s been awhile since I’ve done one). When I get home from work I’ll switch it out for a 47ohm.

Just to update this for people who are interested:
I've re-done my work on the eMMC, even switched to a new eMMC altogether, because the old one has gone through like four reball cycles at this point and I wanted to rule out any issues from that. Now I only used Sn63Pb37 solder and Sn63Pb37 solder paste and made sure to clean the area around the eMMC with an ungodly amount of IPA after I was done. I also used a wire with a 0.04mm diameter for the DAT0 line. Everything works now and I've left the Switch on and in the dock while running Tears of the Kingdom for 36 hours and still, everything works fine, let's hope this time it stays that way.

Giving an update on this after six weeks: The Switch still works absolutely fine. I'd still like to learn the Kamikaze method but right now I feel pretty confident about reballing the eMMCs

Holy hell I finally got it. After rearranging things a dozen times I finally put the mosfet on the front under the shield and it glitched immediately.

There you might have the problem, 2.74 was withdrawn because it was problematic.

v2.74 + 300 mhz precision rp2040 may be not stable at 300mhz

Update your firmware on the chip to atleast 2.75 and test…

And with 100 units i would expect that the installer to atleast keep track of firmwares and atleast know about resistors and the problem to boot ofw if you use the wrong ones.
It’s all in the guide here on this forum, but it feels like some guys make a quick buck after watching youtube…

But thats just me… And i have been around modding consoles since OG xbox and ps2 days..

I use 2.75 very nice but i will use 2.80 or 2.81 firmware after know about what is new on it.

2.81 was created by someone else and should not be used. 2.80 is the latest "real" firmware from rehius.

So I was just thinking. I thought one of the benefits of doing the kamikaze method was that you don’t have to remove the board from the housing. So there must be an alternative RST point right?

Here, but it requires removing the mask to expose the via (just like CLK).

Oh man. I got all the way done with the mod and as I was closing the lcd ribbon connector it snapped off. So I replaced it using what I thought was as little heat as possible. Go to create the emmc and I get this message. Did I fry it?

 

[remlei]

well, since I don't have such console, we can only try messing with attempts and timeouts
(try 2.80)

Thanks for the attempts to fix this issue.

Seriously this issue is actually becoming more common now a days specially with brand new switch units. Its always that **= error code. if the modchip installer saw that error code, they literally gave up on it and use instict nx modchip instead.

I wish I can join the testing but my unit is already replaced with instict nx.

All firmwares should work on the whole range of NS models. I personally test on my Switch Lite

hello. do you recommend upgrading if I'm running 2.75 without issues so far?

Hi, this is my 20~th oled mod and first time having this error..

All diode value ok.. but there is no display at all when turning it on. Even when i disconnected all the fpcb (not booting to OFW)

Suggestion what went wrong and how to fix it?

happened to me but it was a short on the 3v3 line. This oled had error with the wi-fi and I tried a reflow without success. After a day I had that error and with the tester I saw the 3v3 line in dispersion practically. Luckily I solved it with a new reflow on the Wi-Fi chip zones

I just want to share the tinyfly i just install today as i receive all the pieces needed. MASSIVE thanks to @psycho-neon to share your work, the glitch is faster than hwfly clone you can find on Aliexpress. I just forget to adjust the wideness of the board when i ordered the pcb but it fits well in the case. As some people said earlier, yes it is maybe cheaper and faster to buy chips on Ali, but it is so satisfying to do all the process yourself. Moreover you have the control on the quality of every components you buy.

I have another unit with this problem again. I can help test this out before switching to instinct. So far 2.80 still doesn't solve the problem. Switch still boots ofw once in a while.

Do you use the flex cable that is included wit the chips?

I tested both the flex and wires. Made no difference.

Have you used the rp 2040 tiny with same results?
