    Hacking Hardware Picofly - a HWFLY switch modchip

    Thx for tip on CMD resistor. Replaced it and now everything works, currently dumping emmc. Replacing it weren't that bad. With a microscope and some flux it went pretty fast. First time doing 0201 though.

    Hacking Hardware Picofly - a HWFLY switch modchip

    MM I actually soldered one side of the resistor to a lab board to be able to measure it better, if I measured it on the underside I got a 4.8k reading sometimes but not when putting probes on the sides or top. So my guess is that I perhaps burnt the metal. Ordered a smd sample book with 0201...

    Hacking Hardware Picofly - a HWFLY switch modchip

    Thx, tried reflowing the resistor with hot air but still 1.1M ohm. WIll have to find some 0201 4.7k ohm resistors somewhere. I guess 0201 is not so bad but this one sits in an awkward spot. EDIT: removed resistor from board and meassured I guess it's burnt. No reading from it.

    Ah ok, it's a 0201 size? It gets tinier and tinier :) May I ask the reason why it needs to be replaced? What is the supposed stock value? I meassured it inline and get 1.1M Ohm

    Replaced dat0 resistor to 133 ohm. Tested to boot into OFW but get purple screen, I guess I should replace 47 ohm CMD resistor aswell then. Hard to replace resistors on this chip they are so tiny and sit so close to each other :)

    Hacking Hardware Picofly - a HWFLY switch modchip

    AH thx didn't know. I found a couple of 0402 133 ohm resistor's in a practice solder kit. Would 133 ohm work or to far of?

    Hacking Hardware Picofly - a HWFLY switch modchip

    Get 47 ohm readings on the other resistors. Only dat0(C point) resitor which is no reading. Does not look burnt so my guess it was like this from factory. Ordering a few 0402 100 ohms resistor. Can I just disconnect rp2040 chip to boot to ofw or do I need to desolder anything?

    Hacking Hardware Picofly - a HWFLY switch modchip

    Thx didn't know. I remembered incorrectly I did this mod on a switch lite to train soldering and that one had 250ohm when I measured. (On that board it actually worked.) Measured on this OLED board and actually seems that the resistor is broken on this board, don't get any reading at all. Other...

    Hacking Hardware Picofly - a HWFLY switch modchip

    So was happy getting splash screen on my OLED but that turned sour pretty quickly when going to backup emmc. Anyone have any idea what could be the problem? Could it be "ribbon" cable below emmc? Although I got good diode reading. I belive emmc is Samsung, atleast it's not hynix Using this...

    Hacking Hardware Picofly - a HWFLY switch modchip

    Accidently chipped APU when removing "metal bar" on an oled(guess I wasn't carefull enough). Don't know if this is problematic, should i put some uv mask on and hope for the best?

    Thx, yes actually just double checked D just now and resoldered . It's now 0.492V

    Hacking Hardware Picofly - a HWFLY switch modchip

    Does anyone know what the correct diode readings for a switch lite are? Are these in the ballpark?(Meassured with GND on USB port) 3v = 0.748 C = 0.645 A = 0.545 D = 1.310 B = 1.145 GND = 0.05

    Hacking Hardware Picofly - a HWFLY switch modchip

    Decided to practice installing picofly on a switch lite.(My first smd soldering except from practice boards) Wondering if this soldering looks ok but ugly on sp1 and sp2. Sp2 was real hard to get solder to stick and also not touch cap on right. Think I got to much solder on. beep ohm readings...

    Picofly (RP2040) OLED getting error Failed to init eMMC. But with HWFLY working fine.

    Question, where do you place the extra resistor for dat0? Just somewhere inline from dat0? Replacing the 238 ohm resistor even with microscope seems pretty tough.

    Hello considering modding my Zelda oled switch, since it's the homebrew stuff I want to use it for. I have purchased this alieexpress mod chip and I wonder if anyone have had success with these on oled? From my understanding it's a copy of some other modchip kit? Have found this video which...
