It now works with the Zero. I wanted to use the PGA2040, because I was able to grind on some grinding paper until it was really small. This is bigger but this spot appears to be made exactly for this pcb. It fit very snugly. My question now is which payload I am supposed to use. I renamed the "hekate_ctcaer_6.0.2.bin" to payload.bin and tried, no success. I also renamed lockpick-rcm.bin to payload.bin and placed it in root and the payload folder. No success.

I see we are using the same chip (rp2040 one) and it’s doing the same thing (one red blink). When I swap out rp2040 for a hwfly, it work just fine. I’m wondering if it’s the rp2040 one that's the problem.

Same here, rp2040zero works but not rp2040ONE.
Do both of your installs also not boot ofw with CMD connected? If you removed cmd wire would it boot?

You will have red led and no glitch or e no boot from time to time
If properly installed and adequately secured this should not happen. Dat0 adapter works great! You must have pressure against the ball and adapter while securing down and is why adapters with anchors are preferred, i use tweezers to push the adapter in forward the Emmc solder ball while simultaneously soldering the anchors. But not much pressure, don’t want to damage adapter or break the small point on the adapter that makes the connection. I highly recommend the 4 anchor adapter.

Test value of the Dat0 in diode mode (red probe on ground). Before and after soldering down!! Should be between .420V and .800V. (Edited to correct values as my own tested at .428)

Also I would recommend people check with a multimeter afterwards to make sure it's connected.

What is your experince guys with the RP2040-Zero compared to the expensive Hwfly and instinct-nx except for the price. I mean in terms of reliability, boot times , bugs and thermals ? Has someone made a comparison that prior to this installation had one of the other two modchips?

I wonder how many less pages this thread would have if people just used the search function?

1 Big magnifying glass at the top of the page
2 Enter keywords and change drop-down to "This Thread"
3 ?
4 Profit.

It's 2023 and we've been doing 'this' for over TWO DECADES and searching is THE base to using the internet as a whole 🤯😤🫠🤡💩💀

For instance, I couldn't remember reading (another BASE concept that seems to just go over most people's heads) if the HWFly flex cables were exact copies of SX Core flexes. Searched the 2 main PicoFly threads (ew, don't really like continuing the "Fly" name when they copied SX, just IMO though) for "SX Core flex" and had my answer in less than a minute (they are).

The simple fact that these people are asking redundant questions makes me doubt their ability to perform this advanced mod, at all, which then leads to even more redundant posts. It even seems to be happening in the AIO thread, of all places...

Can we add warnings that this is advanced and should not be followed by the mASSes until further notice?

Just saw this on Ali:
US $10.28 | Newest V5 Dat0 Adapter For "D" "A" "C",work with hwfly oled chip v4v5
https://a.aliexpress.com/_mOsRTsK

Since it's preballed, should be fairly 'easy' to remove the emmc with a bottom heater and air wand (required tools, IMO), then just clean up all the pads and put everything back on. Think I'd still want to have a flex adapter to at least get a back up before fully redoing the BGA.


After thinking about it, I believe ^this would just get in the way if you ever needed to do any further emmc\bga reworking. I'm just gonna stick with the dat0 flexes.

That being said, at initial glance it looks like flexes are $10\piece on AliE. Anyone know of better USA pricing?

I'd like to buy in multiple amounts so I can pair them with the 12 PZeros I have coming. For practice, I'm going to use my SX Core flex on my V1 (replacing the SX Core chip) and use the spare V2 flex on one that's sitting here waiting for the PZeros (3 OLEDs are also waiting for me to give them the okay on bringing me their consoles). Since that leaves 10x PZeros that need flexes, I'm thinking of ordering 5x V2 flexes and 5x OLEDs?

Guidance is appreciated.
