Hacking Hardware Picofly - a HWFLY switch modchip

[rehius]

so 2.5_nw then flash unlock over the top or just unlock? or flash unlock if previous fw is installed?

just flash both in any order

 

[nqtal]

fw_2.5_NW - the firmware itself, version with disabled start detection ("Non-Wait")
unlock - just a portion of data that enables HOS running (for any 2.0+ firmware)

Do I need to somehow clear the chip memory from the old firmware or just connect it to the PC via USB with the "boot" button pressed and upload the new firmware?

UPD Answered before my question, sorry)

 

[rehius]

is irfhs8342 and irs8342 mosfet the same?

yes

and where can i buy "~30gauge Kynar or enamel speaker wire"?

"wire wrapping wire" on aliexpress,
or just tear down to fibers any copper power wire for PC motherboard (SATA power, GPU power)

yes. either that, or the Hekate soft-way

Regarding the MOSFETs check the datasheet. For buying wires, here're some options: Ali (takes long time), RS, Digikey or other distributors. Try at your local repairman first

Would thanks to everyone involved and spent his time freely for the community.

Just to clarify to every noob like me that doesn't know nothing in program side.
In order to flash we only need to connect usb and drag and drop the 2 files in the explorer?
Just ordered an oled to test this, if works will try to implement everything inside the best I can.
Can we also remove usb and buttons once flashed?
Thanks again

it should work on this as well which is easier to put into consoles

the flash is very thick there. better to desolder the recommended one

Great reversing work there!
Finally all the people that complained about HOS are now satisfied!
Question though,Does it work on v1 patched consoles too?
I know the boot sequence is different on these (the block reads if i recall) so that is why i m asking.

 

[rehius]

I can say even more, due to the different boot sequence, it works much better on the patched v1

Yeah I would like to know if it works on v2 aswell

yes

how does pico differentiate between erista/mariko?

Thank you for your answer.
Now i can only keep one of these for rebuilding consoles with faulty emmcs...
I had kept a gen1 tx original for that which it now is useless.

By monitoring the boot sequence i guess!

by the different boot sequence, of course

what if emmc is empty?

 

[Phantomas77]

I've a spare CPU flex from HWFLY, should it be ok to use, or would I need thicker wiring as mentioned by rehius?

 

[vittorio]

what if emmc is empty?

hekate start

 

[rehius]

what if emmc is empty?

NS still tries to read it, in a different way in v1/v2

@rehius

Well done friend! Very well done! I guess this means my attempt is no longer worthwhile.

Don’t fret though! I plan to continue simply for the knowledge. Will you still be able to give help?

perfectly fine, use central line
