Guys i've a question. today I get the cpu flat so I haven't installed the rp 2040 yet. But I had flashed the 2.5 firmware. If I want to update the firmware before installing it, just connect it to the pc with the boot button and load the new firmware version right?

yes

Anyone got any good install videos?
also anyone confirmed if the pico fly glitches on the V1 unpatched

know if there is any others for the other consoles?

I can confirm, works on my following test units:
- Erista Unpatched (Toshiba, Samsung)
- Erista Patched (SanDisk, Samsung)
- OLED (SK Hynix)
- Mariko (Samsung)
- Lite (SK Hynix)
- Lite (Samsung)

Thank you, i tried 2.65 with same result
i will try older versions too

could you please give more information regarding your console?
(eMMC hekate info, DRAM hekate info, revision?)

try the firmware with x2 "fast timeout" timings, the only thing I can think of

what mosfet are you using?

I am still getting pink and ofw. Tried with 20 ohm on rst. CMD, CLK and DAT0 tried with 100 ohm and without resistors(no ofw boot in this case), but the same result - pink (rgb mode is ok, red on flash). Tried different fw includes one for think wires and the last one which was a few posts ago. Where is my trouble? May be toshiba nand? (how i can check it without hecate)? My console is patched erista.

show where the each wire goes, might be wrong connection

I am struggling to find any compatible parts online in Turkey. I have find the parts below;

RP2040-One This is available in a local shop or,
Raspberry pi pico This one is also available. Which one to chose?

Also there are no recommended mosfet I can find so far. From my research I find mosfet below;

NTMFS4119N 30V 11A mosfet with small package. Are there any specifications for mosfet? RDS resistance, max capacitance, Current, Voltage capabilities etc.

I am planning to mod an OLED I have emmc adapter for it.

Are these available for you BUK6D22-30EX ? These are pin compatible and have nearly the same characteristics but havent tested them yet.

29 - DAT0, 28 - CMD, 17 - CLK. Seems like theese points soldered correctly. Anything else? I heard on 4pda thats it may work only with 47 ohm resisters in some cases. I am not sure about cpu, but light should be cyan.

The rp2040-one fits better, try and get a flex cable from Ali if you can't find the recommended mosfet

can you upload photos of your work?

@rehius were are the firmwares being uploaded?
Thx for all you work!

I mean show photos of the board, since it's hard to see where exactly those wires are soldered to. My diagrams assume soldering directly to the eMMC board, or, at least, to its header, I am unaware of other points. Just wanted to check

In the same message you just quoted

hello sir rehius, whats the difference between the normal uf and this new x2 timeout and the previous x1 timeout-ish? the other day. i will be using v3 oled flex cable soldering both resistors


Also guys, been researching for the past 2 months, somehow i already got the gist, but what are the particular specific issues or notes i should know about? like...

-RST point is very sensitive so make sure to clean it properly without flux leaving behind and covering some tape...

-Adding additional resistors if it doesnt work...

-20k resistor for RST if it does not work..

anymore?
