Hacking Hardware Picofly - a HWFLY switch modchip

[raksmey1231]

Hi everyone, I lost the five pads and I measured it all on a new OLED Motherboard but it did not show any value. however, when I connected the LCD cable and measured it again and it did show value. Are all the pads have no connection or sth else? thanks

Hi @rehius , I wanted to express my gratitude for the incredible effort you put into creating this mod. Thanks to your mod, I was able to sell some modded switches and generate enough money to purchase a new MacBook Pro and Sony Xperia 1 V. I am truly thankful to you for enabling me to achieve all of this. Once again, thank you so much, bro!

measure them in resistance mode,
they should be no connection. Put on new fpc connector and good to go

Thank you @Dee87 and @abal1000x for your valuable inputs, I do have a green adaptor that I bought and will use on this. This is going to be an exciting challenge. I no longer see any reason to get frustrated when killing a console, I learn and enjoy.

@rehius that's 10 now

good luck reballing Apu and emmc

After installing hwfly boot chip end boot to red light and nex try boot same red light now console not boot. ****

Hi !!

I hack my second Oled and it work fine but now it boot on official and i have this error "=* D0 is not connected"

I see my DT0 and its ok, but i have always this error...

fixed, dt0 was the problem

What is your diode reading for DAT 0?

YSK that the green adapters have pretty bad quality on the preapplied solder balls and it may have to be reballed (on both sides) before using. On about half the adapters in the latest batch I bought, the balls were so uneven in size that some of them did not connect properly. Make sure to measure all important points after attaching the adapter, before attaching emmc. (vddi, vcc, vccq, dat0-7, ds, clk, cmd, gnd)

Thank you for this. I got the diagram ready and planning to go fully surgical on this task. Wish me luck.

Didnt work with one mosfet. Tomorrow i add a second one.

some of those aren't connected to anything and the naming in your diagram is a bit odd. use this one instead

I desolder B and C im lost.

 

[jkyoho]

I desolder B and C im lost.

Where did you solder B on HWFLY?

Where did you solder B on HWFLY?View attachment 383802

This pic after desolder.. I soldering B point on B...

what's your purple cable diode reading at that situation? More like you desolder/solder B cable to a ground point IMO

 

[cowboy619]

diode readings for all points - ps personally i don't like the flexes

I never soldring B point to ground. You want me to read B? It was two try boot but end to red light. Now not booting at all.

Multimater red on point and black on ground

Dat0 is 0.675 v
CLK is D point 0.502 v
A Point is 0.670 v
3v3 point is 0.805
B point is 0 if read red on ground and black on point is 0.414v
Ground point is 0

Hi Guys. Go easy on your boy, but I messed up on this OLED big time. I kept getting *== and I would grind the CLK more and more to hopefully get a glitch going but instead, I ended up with this: (VIEWERS DISCRETION ADVISED):

Looking at the bright side, I've always wanted to learn how to work with emmc, I'll just give it a go and see if I could solder CLK directly into it.

Notes:
I still get 0.6v on multimeter when I point it on the trace right beneath the APU (tried soldering there, no luck)
I've changed the pico and re-wired the whole thing.

For new comers:
THIS IS INSTALLER's fault.

Jesus, this is what I end up with.... ready to be soldered to.
I would say to the bad modders that you should be treating each console as your own.
A bit of respect

This is it... how do we repay him?

I'm more of a beginner modder. I don't leave my clients dry. I reimburse them with Amazon Gift cards so they can buy whatever color of their model.

A Point is 0.670 v
3v3 point is 0.805
B point is 0 if read red on ground and black on point is 0.414v
Ground point is 0

clk is a tad low and b should be around 2.9v

Would this modchip belong to this thread?

If so, I'll ask mods to move one post of mine to here...

That's a HWFLY modchip bud
