Hacking Hardware Picofly - a HWFLY switch modchip

[Dee87]

so are the picofly apu flex cables, the same cables used in the hwfly?

picofly doesnt have its own flexcable most people use them from hwfly or just install mosfets

@LogicalMadness
and everybody else who are interested in reballing emmc without magnetic stencil holder

i was trying to fix some defektive emmcs today fixed 2 out of 3 and one with slow speed issues by reballing them and is was getting quit annoying to hold down the stecil perfect all the time while applying solder mask and then heating then up so i "Built" my own magnetic stencel holder quickly.

with 4 small magnet and 3 layer of doublesided tape under the emmc for the perfect hight if u try it this way make sure u push with a twezzer i the middle when u apply heat other wise the stecil will come up while applying heat

I admire your ingenuity, I'll add that to the list of things to try in the future.

Hello. At last I have received all the necessary parts and in a few days I will try to install Picofly.

I have read many posts in this thread and there are things that are not entirely clear to me.

I am going to use awg30 cable, although they have recommended me to use 24 or 26 for the ground and 3.3 points. It is advisable?

What should I do if I get the installation to go well? I have read about backups of emmc, keys and so on. In the past I installed hekate via the jig and I seem to remember that I only backed up the nand before partitioning the MicroSD.

What pack or hekate do you recommend putting in the microSD?

I hope you help me and sorry for so much text.

Thank you so much

For the love of all things god and holy (and my sanity) do a full complete system backup (emmc + boot 0/1 + keys) then back them up

Just pointing out that so far this place has next to no orders and the original "official" store is 50% more expensive. Hopefully it's legitimate.

Open question: ignoring price, objectively is this Instinct chip better or worse than a well installed picofly?

Not sure on the seller, but the chip itself is legit and better than hwfly

Well, today I do mi first picofly installation and everything works fine, except when I try to lunch EMMC partition

What I do wrong?

actually cannot enter to OFW to

i soldered the 3 47 ohms resistors in the CLK, DAT0 and CMD points.

You need to run the unlock.bin but backup boot0 first

Oh! Yeah, I forgot that, thanks, and yeah I back up the EMMC and B00T0 and 1

dont forget your keys

u flash the rp2040 after u should get a succes color after u draged the required files in the rp2040 folder that appers and if u get green after flashing it it means u need to set rgb mode , if u get red u dont need to set rgb mode

Hello. Thanks for explaining this, but I'm a little confused with the red led part. After flashing the firmware and plugging my rp2040, I get a blue light then a purple light, no red. Am I okey with this?

I will install it tomorrow, Waiting for my flex cable

Replugging might not have the same effect. You should be getting either a green or red led RIGHT after you program.

Hello nothing installed yet and did some backreading. I know its necessary for 47ohm resistor. But is it necessary for 20K ohm resistor for RST pin? I have smd 20k lying around is it bad to attach assuming everything is fine?

20k on rst is only needed if you have blue then green success glitching but reset right after. So if you have no problems booting then you don't need it.

That's right. I tried it again and got a red led. However, I did not understand what Dee87 said about the red led not needing RGB while green does:

after u draged the required files in the rp2040 folder that appers and if u get green after flashing it it means u need to set rgb mode , if u get red u dont need to set rgb mode

I got a red color right after programming. When replugging I get a blue then white. I asked for advice here and Redius recommended I set RGB jumper, when I did that. Now I get a blue and then purple when plugging.

I'm sorry if this a silly question, but will a 47ohms carbon resistor work? They don't sell SMDs in my local store

If you get red led after programming then do not touch the rgb jumper.

47ohm THT resistor will technically work, but its likely going to be too big to close the console up and I've heard there can be electrical interference with those as they have much more mass than smd resistors.

Got it. Thank you!

I am getting some odd behavior on my V2..

Install seems to work fine on fw 2.6 (had to do RGB jumper), loaded latests HATs pack onto SD card

Booted in Hekate back up boot0/1, keys, nand

1. I can't boot into OFW, after nintendo screen it goes to what into some loading screen for 5-10 seconds then reboots
2. If I launch into CFW using EMUMMC I can't log into wifi
3. If I launch into CFW using SYSNAND wifi works fine

Card is 64gb fat32, EMUMMC is partition, sys fw is 16

When I disconnected the rp2040 the system boots fine.

Hello. I'd like to thank the devs for this great job. One question if I may: When I flashed my rp2040 and re-plugged it. It gives a blue light then white, I saw a video on YouTube where it shows a purple color, not white. Am I good or is there something wrong? Video attached, Thanks.

need to set RGB jumper

I have few rp2040 zero chips.
On one of them LED works from beginning - red after firmware 2.6 and blue > purple after connecting to PC.
On other there no LED at all. When I set RGB bridge, LED works but with different color - green after firmware and blue > cyan (white?) after PC connecting.
So I set RGB bridge to another and colors change like on 2nd chip
So I think it's absolutely normal

 

[Kiuxn]

I have a question, V2.6. Remove PR2040, OFW cannot start normally, and everything is normal after installing pr2040. Try to restore clean boot0, which is invalid.
When I disconnected the rp2040, the system started abnormally.

Interesting. your 2nd chip sounds just like mine. Please explain what do you mean by " set RBG to another" ? Did you bridge different points from this diagram?
