Hacking Hardware Picofly - a HWFLY switch modchip

You're absolutely right. I did ripped the pad

Is there a way to "fix" this?

DAT0 DAT2 all need to fix prior to get mainboard works again.
FYI, CMD line right pad looks suspicious as well

I think it's a weird angle and flash that he took of a "solder peak" in the other photo, but this is their earlier photo showing Dat2 doesn't appear to be ripped.

I hope so, but who know what happened when removing the wire, no to mentioned non-solder(golden) before and soldered after

Repaired the DAT0 pad and got it working!!! Thank you very much guys!

Ps.: Other pads were ok. Just lightning on the photo wasn't good.

Got a picture of the fixed pad? I'm happy for you! XD

I didn't. Was so excited that I just finished the installation ASAP. Here's one I just took (won't chance remove the rp2040). It's a weird angle but I think it's ok to check how it went.

Edit - Turns out the batch of tinys were not the problem.

Hello guys! There's any problem in solderind points dat0,cmd,clk and rst whit 0.1mm enammeled wire?
I use 0.32 awg, but feel few dificult in any points.
I decide use 0.32 awg in 3.3v, gnd, cpu and use 0.1 enammeled wire in cmd,clk,dat0, rst.
I bought this wire 0.1 in aliexpress.

no problem at all... ground, 3.3v, Cpu using awg30. else is 0.1 enamel. Been doing that since long.

Pricewise is 0.1mm enameled.

For a more pricier you could use 34awg, 36awg, 40awg isolated wire.

You could search on @NooBziN message post for picture.
I think he made the most beautiful mod on this.
I remember he said using something like 34awg.

Hi, if you check a few pages back you can find the suggested seller as well:
https://a.aliexpress.com/_EvsZTb1

I also bought from this shop and it's ok both in shipping times and quality. I am in no way associated with this shop.

U can use 0.1mm for everything there is no need for thicker on 3.3v and and.

I used it on my first 60 installs , now I'm using 0.2mm.

But eather way never had an issue with 0.1mm

Is there a easy way to check if it's fake or not without having to install it?

Generaly the chips should have thr waveshare logo on them, but that might also be copied. Last time I checked buying the rp2040 zero/tiny directly from waveshare is cheaper than aliexpress, but it might not be the case where you live.

Yes here the same - RP2040 OLED Installation - At the NAND Backup over Hakete the screen has freeze at 83% and now OFW allways in bluescreen. The RP2040 works fine but don't start anything from SD.

CFW = Blackscreen
OFW = Bluescreen

Caused maybe by a short circuit at Dat0 and Dat1

Anyone know a picofly firmware that boots direct into hakete ? Load from RP2040 Chip and not from SD.

I got now over the ums-loader and nxnandmanager my nand dump but i still need my biskeys for decrypt it.
If I start lockpick_rcm or biskeydump both renamed as payload.bin over the pico chip i got still a black screen.

Does anyone know how else I can get my Biskeys?

Hekate, lockpick_rcm and biskeydump = Blackscreen
OFW = Bluescreen

Only ums-loader works as payload.bin maybe this only works because it is started from memory.

How many did u buy and what did u pay for I would like to get 1 or 2 off of u to see what the issue is with them

"Normally"
They should also work

Hello, I'd like your input on this, guys.
Picofly installed nicely on OLED and worked fine for a week. Now I get "eMMC slow mode" but not on the main hekate screen but when I create eMMUC.
Furthermore, eMMC tab shows the error with 0 bus speed.
OFW > purple screen.
CFW > failed to init eMMC, failed launch HOS

Do you guys think this is fixable with adding resistors on Dat0,CMD?, or is it a CMD resistor issue?, or eMMC?

An update regarding OLED going slow emmc after one week of full functionality.
The console is now working and currently being backed up

I first removed the dat0 adaptor and resoldered CMD resistor (it has the correct value) but still purple. While checking my work I noticed some flux remnants on RST, and I remember reading it is a very sensitive point. I cleaned the crap out of it and it did boot.

As weird as it sounds, that's what got it to work.

Thanks for all your inputs.

Can you try to measure your flux using ohm meter, to get a gist its conductivity?

Sure I can. Just tell me how.

It's a mechanic.

Thanks for the update. It's always good to see the solution to these weird issues.
I had a similar problem a while back (with hwfly) https://gbatemp.net/threads/help-weird-oled-issue-after-chip-installation.630850/ , still not sure if it was flux or the flex cable but after all this time now and all the info gathered from this thread I guess that flux residue might have been the problem.
