Hacking Hardware Picofly - a HWFLY switch modchip

[juanvlc]

Too may posts in this tread, there won't be many ppl see this warning. It's better to give the seller a bad review, put the warning in the review. It will help both seller and buyers to avoid that adaptor.

I've opened a dispute and will leave a bad review for sure, but that is useless. Seller only will accept refund if I return the goods to China so money is lost. Also, he will close the sell and will open a new one and continue scamming buyers. That's the way greedy Aliexpress sellers acts.
I prefer post this here and aware mates about this seller because people here, surely, don't buy one or two units like regular Ali buyers do.

Or stick some good links in the first post of the thread so that people have a chance to take a look at them!

Stating a fact is not you being a dick, it’s just stating facts. The reason for that many failed consoles is blue screen of death. I killed many APUs because I grined the GND point on the APU. So that failure rate is very much well-deserved for not following Standards .

Ever since I figured it out and started using the shield as ground I have not had any failures. I’m well into my 6th console with straight success.

Ahh okay that makes sense. I wasn't sure if you meant the issue was because of the Pico mod or if you had evidence it was a user error. And yeah that ground pad sucks to solder to. I started using HWFLY Flex cables and cutting the connector off and soldering to the resistor near the mosfets setups because it saves me a lot of time and you don't even have to cut the shield. I haven't killed any consoles yet (touch wood) but it takes me a very long time to do each console because I am quite obsessive and clean them a lot as I go and I spend ages curing solder mask lol. So I have improvements to make for sure. I am glad you found a method that is working now and not losing consoles.

This board has a record of damaging EMMC in my locality

This board works fine. The dat0 adapters provided with this board are horrible. The dat0 adapters are the cause of the damaged emmcs, not the board itself. I have bought from these.

Edit: Look at these adapters.
Number 1 and 2 came from a batch from a store that later shipped bad adapters. These adapter are the real deal.
Number 3 came with intinct-nx chip. This will also work fine.
Number 4 came with the board you mention. Now this is how a horrible adapter looks like. Never use something like that.

I have mostly done oled consoles. Maybe not much old switch consoles in my place. With such adapters i never had a dead console. After many installations. I also havent got any returns yet due to adapter installation.

Easy to see what is the dangerous one right? Several times discussed here
U´r wellcome

Another seller sent me those terrible adapters, can't do anything with them.

Does anyone know a good seller for the dat0 adapters?

 

[vittorio]

probably the chip they sell has an old firmware

anyone got a link to buy picofly chip with flex cable ?

guys i installed picofly a week ago.
I shipped the console to the customer, and when he received it, it always boots into OFW.
Even removing the microsd, the screen does not appear. I seem to have read some comments with the same problem, but I don't remember the solution.
It's something that happened to me in the past and I solved it by changing the rp2040-zero with another one.
Now unfortunately the conole is not here with me, can I do something remotely?

Hi all.

Soldering in legs of emmc connector I bridge 3v3 and Rst line from CPU to emmc, my bad but I cant see this in hours because bridge is under connector and from top cant see, only see with the board inclined.

Now no shorts, max77620 supply all voltages but max 77812 no.

Stuck at 120mah at boot, the question is can 3v3 and rst bridge kill the emmc or the CPU?

Tomorrow I will install picofly to see if can boot to sd or RAM.

And check emmc activity with oscilloscope.

Greetings.

Hi.
I have a v2 switch and i installed picofly with flex cable. I used the 3v point on the emmc. The console boots in to ofw, i dont get the no sd card logo. I am on the latest 2.74 fw. And the error light is =*== eMMC test failure - read failed. This means do i have to try to use 100ohm resistors instead of 47? Thank you

This is a video of failiture.

This is a video of failiture.

To me it looks like ==* CPU always reach BCT check (no glitch reaction, checkmosfet)

So check point 15 on the Pico and the connection to the mosfets / CPU cable and the caps is what I would do.

I have no chance to try, it's not with me. This video was made by the customer.
Can I reset the picofly when it's installed on the switch? Does it have to be powered or is a jumper enough even without power?

Can someone point of what I’m doing wrong, the red pointer is where I had the cpu

Ahh I see. I think the reset points are on the back of the Pico. I am not sure hopefully someone else knows.

the points are 1 and 0, I mean, does it work with the current disconnected? Or does the chip need to be powered?

I Believe your red point goes to the Drain on the mosfet,where your top sp1,sp2 solder point. You can check it with multimeter.
You should use the left side resistor as the Gate point/CPU

Do not buy from this seller, scammed me with the dangerous dat0 adaptors.
Advertise the good ones but ship the dangerous ones.
Be carefull

well its ur own fault why do u buy dat0 adapter do it the proper way and reball the emmc, specially if u offer it to customers.

these dat 0 adapter will always give u issues since there is no proper connection .
if u want a proper connection and not offer a half ass job specially when u make money on it then learn how to reball if u dont wanna do that u deserved to get scammed , as the matter of the fact even if u do it for ur self and use a dat0 adapter then its ur own fault.
A real tecnichian would never install a dat0 adapter and sleep well at night if he takes any pride on his work.

thats my 2 cents to all these discussions on the Dat0 Adapters
