No, I don't think it's fake, I think it's an old and flaky firmware and you got lucky for some reason we've yet to determine.

I'm not the only person that has successfully installed in here... I will install one in my oled to prove a point if I have to...

Ive also flashed this rp multiple times

Gentlemen it's useless to get lost on the diagrams, it works, it doesn't work.....everything works perfectly I'm testing it on mariko do you want my video too? the firmware is missing we have to focus on that

We know it can work, that's not in question.

Can I ask have you tried using a hwfly/sx to confirm you have installed right.

Does it still boot into OFW correctly

Originally when I installed into the lite I couldn't get the sx to load, would fail to glitch... I put the rp in and was getting the yellow led(dat0) sure enough I had accidentally grounded dat0 against the cover directly next to it.

I have a lite working, kingdede has a mariko, the only one we haven't tested is an oled... But I'm happy to pull my oled apart to test this just to prove it works if needs be.

I have a mariko I could test on aswell if its really needed.

I would find it nice if you would make an video and Show how you did it.

How I did what exactly???

I used the install picture from page 34...

And what files did you used?

Yeah OFW is working as long as I disconnect the chip, I'll do a more thorough investigation later today. Would you mind grabbing diode mode readings? That'll be helpful for troubleshooting. I'm wondering if the values would be the same as with HWFLY or if it's affected by the presence of the chip in any way.

And what files did you used?

The file is also on page 34, remove the .pdf from the end since .uf2 can't be shared directly on the forum

 

[Tafty]

And what files did you used?

The Ubuntu uf2 which is also on the same post on page 34!!!!!!!!!!!!!!!!!

Where did you get the software flashed on the rp2040 ? Thats what i meant

Page 34 like I said, the uf2 file is attached to the same post the install diagram is.
I plugged the rp into my pc in boot mode(holding the boot button) then copied the uf2 on to the rp internal memory... Job done

 

[binkinator]

I don't know guys. My jury is still out.

@Tafty could you please film yourself soldering the wires whilst wearing an England 1982 home shirt with 'tafty220223' written across the back in Sharpie?

 

[rulles]

anyone with this chip installed in mariko can inform if have space inside to put the chip?

You will need to trim the metal heatshield the same as sx or hwfly, you may be able to squeeze it under BUT there is a big risk of shorting it out as there is a voltahe regulator on the bottom and obviously exposed points on the top

in the diagrams,appear one component solder directly to cpu, i think that was the mosfet.
if i use a flex cable (v2), don´t need that right?

but if i use kapton tape, don´t eliminate the risk of shorting?

Yep the flex has mosfets on it allready, just bridge pin 3 and 4 onto the end of the flex and solder your wire to them, be careful around pin 1 2 5 6 as these are grounds.
