You don't even need the heatsink for testing. It can run quite a while in Hekate/Bootscreen before it gets too warm.
so i just need to plug the battery in?

When you flashed the fw what color led flashed, red or green? It should be red if not solder thw rgb jumper
The brushing firmware is red, and it worked normally in version 2.64 (green).

I confirm that my 2040 colour display is normal (no RGB jumper is required)

I need help, since yesterday I have an oled board that works but when I put the screws on the bottom of the console, or just tighten it with my hand, it no longer turns on, I have already insulated the entire board thinking that it could be grounding but it's still the same Does anyone have any ideas, thanks...

I assume something is grounding that shouldn't be, do you have photos of your install?

LED must be RED after USB write. if you see green, set "RGB mode" jumper

WHITE = eMMC write
BLUE = glitch
PURPLE = eMMC boot failure, check CMD / CLK
YELLOW = eMMC write failure, check D0 / unsupported eMMC
CYAN = no reaction to glitch, check mosfet wire
GREEN = success

I already uploaded a photo of the bottom part, that is, it should be there since the damage occurs when pressing the plate, that is, I understand that it should not be at the top

Photos, more precisely of where all your joints are, where the pico is, etc; for it not to be working when you screw it up tells me it's shorting somewhere it shouldn't be.

Obviously, I encountered a colour (red) outside the list. 2040 has been replaced, and it is currently working normally.

I check the points of the chip when the console does not turn on and none of them, except for the gnd, show ground, so I think that the connections are good

My friend's switch lite let me help repair, but his data0 point is broken, the original has been installed 2.5 picofly, but now can not boot, please ask this how to continue to install picofly. thanx
DATA0 has an alternative point. But you may need to repair the damaged line.

Is mosfet installed in this way? What I know is that it requires a certain amount of current to run, and it is not recommended to install it like this.

yeah i saw someone use that point...
is there another spot i can use ??
There are too many points connected to GND. Use general instruments to detect them.

I just modded a lite with a rp2040-zero and single mosfet, worked perfectly first time. My reflections are:
- attaching mosfet directly to the cap is not a good idea. the mosfet is taller than the apu and will lead to bad thermal conductivity since the shield will cover both apu and mosfet. I put the mosfet in the space between apu and ram.

- Soldering mosfet to caps (with or without wire) is hard as hell. By far the hardest part of the mod. Absolutely not worth the extra time it takes over buying the ribbon cable.

- There is no way to fit a 2040-zero under the full body heat shield, even if connector and buttons are removed. If someone claims they did then their heat shield is bent to hell and will cause a bulge in the housing. A hole in the shield is necessary.

- single mosfet attached by wire to single cap seems to work fine.
- working with solder mask is messy and spreads everywhere unless dried enough. Maybe it's just my shitty aliexpress product though.

Thanks everyone, especially rehius!
