While you are waiting for the v2.6, here is v2.5 with increased timeouts, hopefully should fix the Toshiba case

hi! will try this today, thank you, this includes unlock or still have to flash separately?

space constrains.

guys why rp 2040 .......usb and both reset buttons are removed while installing it in switch i mean why its mandatory ?? any reason ??

without USB & buttons it nicely fits without cutting the metal casing

I was able to fit the whole rp2040, but even with cutting I got a small dent in the case, it's pretty thick + there is no much space

Chip thickness. So that lid can close.

just regular 2.5
if you use the same chip, unlock is not erased when flashing the new firmware

hello, if I have the flex cables of the hwfly for the V2, Lite or Oled, should I still solder "irfsh8342" and the resistors? thanks for the great job btw

Someone need to build a special shield that can make you keep the buttons

Did you flash the unlock file?

Can anyone confirm the stability of the RP2040 ZERO on the switch is it better or the same as HWFLY?

rp2040 is better

Hey guys, long time lurker first time poster. Finally did the mod, it glitches and boots Hekate fine. Using 51ohm resistors because I read somewhere that Toshiba eMMC's prefer a higher resistance. I ran the picofly unlocker payload and all that and it said it flashed successfully.

Anyways, I get this error anytime I try to boot Stock or EmuMMC. I'm also seeing that my secure boot key is all F's and my Cal0 is corrut.

hey, I work on this in my free time, and this $3 shit (with mismatching 3.3v/1.8v voltage levels!!) already outperforms hardware fast FPGAs thx to algorithms.

hwfly doesn't work with SanDisk at all, and with this fix, Toshiba should be fine

gimme some time, the todo list for 2.6 is

- fix HOS auto-off code
- software update support
- remove encryption
- faster PIO sniff
- rework OFW-related things

Using logic level shifter or something?

magic. rp2040 picofly fully works with 1.8 eMMC signals at 50 MHz without any additional hardware being powered with 3.3v

Wow thats cool

so, the wiring is the same use 47 ohm resistor or without it?

Resistor 470R or 470K ??

R RESISTOR

yes, resistor only to avoid noise.

Danook28 · Mar 28, 2023

Use also 20R smd resistor on rest on chip....
