Hacking PicoFly D0 is not connected (=*)

[Shadow42]

I installed a picoFLy for my Switch OLED but after booting it up I got this error "D0 is not connected".
After some research I found out that people getting this error normally can boot up on the OFW as normal, but I can't.
I tried removing the D0 connector and reanchoring it again but nothing seems to work, could the chip (I think it is the NAND) get damaged?
I would appreciate if somebody could tell me their experience with this issue and how did you solve it.

Did you measure the values beforehand or just blindly solder them and start the console?

Normally the emmc ('the chip') doesn't get damaged if the D0 is not connected so it likely is something else.
There is a dedicated thread about the Picofly.

As mentioned already, first thing to do is to check some connections with a multimeter in diode mode.
If you got yourself a nice picofly board from Aliexpress, also measure your resistors as someone in China messed up the values with some boards.
If you can't find anything, just post the detailed information and pictures to the thread above.

I think it'd be best if you showed us pictures of all your soldering

I didn't at first...
I have a multimiter but dont really know how, I discovered that my issue is not the eMMC it is the screen ribbon cable
Because my touchscreen works as normal but I dont get any image, except when it is docked

What happens if values are below what they are supposed to be?

 

[MoeXzl]

If the values are below standard, there are only two main causes. No correct connection or you measured differently. Usually you measure in diode mode with red to ground. Most people do it the other way round and then get different values.

Got it, thanks.
I think my multimiter's battery is low so sometimes he gives wrong values too
Thanks again.
