yep

 

[fabjef]

yep

you can use the mod on the last page where that temper replaced the USB port by a ribbon connector, then solder the conector to a ribbon cable. or you can just put a temporary connector soldering the only 4 cables needed, +5v, GND, D+ & D-

ohmygod. my brain will explode. can you provide me a link .thank you so much !

they are isolated with uv mask

Ok that makes sense, however in this post https://gbatemp.net/threads/picofly-a-hwfly-switch-modchip.622701/page-135#post-10107313

the user @billybobxxx does not even touch second capacitor, he soldered only to the first one.

So which approach is better?

it easy, using search function:

I think he used a ps controller connector.

by the way you can buy the ps controller connection and ribbon just like this one:

better test it before u remove it, if not u still need to solder it back

Well just do it like u feel , I wanted to do it that way first to but I changed my mind so did it that way I ended up needing to mosfets so glad I did it that way

 

[icantfly]

do you need 2nd mosfet only if cap is removed?

 

[impeeza]

I didn't understand, but you need 1 mosfet connected preferably to 2 capacitors.

was talking about this where cap was removed and guy was having problems glitching with a single mosfet

its better to read the important post at top, there are several examples of correct installation.

so far SciresM has been put anything on github repo.

Seems the changes are small:

"Version 16.0.1 is out. The official patch notes state “stability” as the sole change. Internally, the bad words lists were rearranged to reduce erroneous blocking, and various words were added/removed in some languages.

"The “BCAT” system module was changed in some way, but I’m not sure how. That being said, it's probably a bug fix (or fixes?) given how difference reports show no major changes.
And… that’s it."

So... I've been following this for a while now, seeing how you all are excited and stuff made me order an Rp2040 zero, V2 hwfly cable set and a set of 470K SMD resistors and a soldiering kit... I have a V2 Mariko Nintendo switch... Hope that will be everything i need to get going

You got all that right but the resistors - They are 47Ohm not 470 and not 470k

Oh really? So these will not work?

If 47 Ohms not on there then nope. Make sure not 470 and def not 470k. I did a v1 patched erista without resistors and hekate stated emmc in slow mode yet all loaded fine ofw, cfw and emu cfw. I ordered the right resistors and waiting to see if slow mode goes away with 47 Ohms.

Can u link the ones you've ordered please?

I ordered 2 diff sizes to see what I like better

We need one guide with all this info and what pin to solder on cpu flex for all versions so the same questions don't keep getting asked and so it helps everyone out. I know there is an AIO thread just started but its still needs more info.

Oh right that... man someone need to donate an OLED to KreaktivDax so he can do one of these and Balilak011 updates his site - https://balika011.hu/switch/

They acutally secretly uploaded OLED scan but very slow loading time for each layer.
