Picofly AIO Thread

Anyone know where I can find a flex for a v1 Erista? I'm interested in trying this mod but my free-hand soldering isn't the best.

select the same one as in photo

Any alternative point. For cmd and clk point. Is to hard. Coz is to near

is there an alternative point? for cmd and clk.? for being too close

Awesome, thanks, and you don't need the MOSFET If you're using the flex?

Flex already has mosfet attached

Try Aliexperss or use low cost mosfet

I'm more concerned with ruining the SoC than ruining a MOSFET, I've picked up a pair of flexes for my switches, gonna grab a pair of rp2040-one now

Hello.All videos show only chip soldering. Do I need to install something to the sd card? Or should I insert a blank formatted sd card?

This is correct?
Panasonic 47ohm, 0805 (2012M) SMD Resistor =5% 0.5w


I noticed they also have the exact same but they are +1 0.25w

Hi! My 4th picofly, have done 1 oled and 2 lites always with flex cable with no problem
Was doing a V1, measured all diode values before turn on, all good but, forgot to attach the emmc chip, turn the switch on, the chip only showed blue light and then turned off...And now doesnt turn on anymore
Did tried many things but since then I have a lot of shorts everywhere (red in image)
The cpu is dead right?

Forgeting to connect the emmc did not cause this issue.
Most likely you only have one short somewhere but now it registers throughout the whole pcb.
Try to visualy inspect all the places you soldered and see if you can spot a bridge somewhere. If not, check to see if you can see any discolored component (capacitor or power controller).
Another option is to use a rosin atomizer (check on aliexpress) and plugin the battery for short period to spot where the short is.
The easiest way would be to send it to a phone repair shop and they should be able to find the issue in no time (having the right tools helps alot)

Did you check these areas?
It looks like there is a bridge between those 2 caps.
Also it looks like there is some solder residue on the screw hole copper plate.
Maybe the photo is not so good.

Thanks @QuiTim
Yeah I have look carefully many times but cant find
The first image I've already measure and its not shorting, just checked second image seems cleared
Didn't know about that rosin atomizer that would definitely helps, I was thinking about buying a thermal camera and inject voltage like I seen on some videos. Guess I'm gonna try that option first

My install works on my lite, but it takes a long time to boot and when it does it shows a red light rather than a green one. Besdies that, its working fine and I dumped my nand with no slow mode/ any other issue, whats the cause for this?

 

[SiggiBartman]

YES YOU MUST BRIDGING THIS TWO POINTS

What can i do if i´ve broken all the normal pads? And which pins should i bridge? Switch doesn't boot, so i assume d0 is broken? Is it essential that the clock and cmd pads are connected too?

Add 33ohm to rst will boot faster / add 100ohm to dat0 it will help or try retrain chup by picofly tool

 

[zorusgb]

Why the two wires to the Pico if they both go to a single point on it?

Right. Then run a single wire from, the now bridged sources, to the ground point. And two wires from the gate points to CPU (at the pico). Got it.

Yes it is looking for a payload.bin on SD card. The PicoFly guide talks about this. You can follow any other switch cfw/atmosphere guide to allow homebrew.

This will work without issue for the MOSFETS on an OLED?

Yes I use 30awg like that for my mosfets.

Just strip the ends as usual and good to go?
