Hacking Hardware Picofly - a HWFLY switch modchip

47+47 also okay.

Thanks i will try that

hi, thanks for the replies

it was booting ok (OFW) before installing the Pico...I used the 3v from the eMMC Module...

...the eMMC can still be accessed by Hekate and not in Slow Mode...

...I might have to try going 100 ohms on the CMD as @abal1000x suggested.. though I'll have to find a 100 ohms resistor if I have one... will 47 + 47 ohm work?

Thanks

3.3v don't require thick wire. 0.1mm should work fine.

Edit: btw install looks clean. nice

the cable need some reroute for tidy and fit to the shield. To my opinion, a little too thick. and the resistor should sit on the pico board so it not touch other things

...hi again, I tried to add resistance to CMD as suggested....

..but still..

I recovered the switch with same issue because boot 0 and boot 1 are corrupted. But lets wait for more advice from others

I think you are right. We have seen this same issue happening a couple of times.

...on pico, I was initially using the 2.74 FW and tried to downgrade it to 2.73 thinking it might have an effect on it...same result

After adding the resistor but still the same, its highly probable that the partition corrupted.

Hello, does anyone know the value of that capacitor? The one inside the white circle

 

[LazarusGX4]

...even EmuMMC blackscreens...

..I already done:

- recovering sysMMC from backup
- trying donor eMMC
- re installing BOOT 0 & 1
- creating EmuMMC...

..probably it son the Hardware side now..

..already ordred eMMC Module on Ali... see if it works..

Sorry i ask a lot.
If without microsd, when nosd shows, you press vol+ and vol-.
Can it boot to ofw?

...nope, blackscreen also...

You can inter cfw???

no, only Hecate... Atmosphere hangs on splash screen when I try to load Fusee Payload...

You really do nand backup. Where you soldring picofly motherbord point???? If on mmc can i see soldring point me be soldring 3v3 wrong point.

..I have done eMMC backup after installing PicoFly...

..I soldered the 3.3v to this point on the eMMC Board...

If the backup is good and full nand for this console that safe way to replace mmc and see what well happend after.

 

[jkyoho]

Use NxNandManager to check the backup. I doubt you just backup a corrupted eMMC backup if you never been able boot up normal after picofly installed.

If temperature out of the variable, then the RST line, need to be inspect.

What one of this test points You recomend ? . Any issue if i conect to the 2 test points for solid conection ?
