hi
i was having problems with my Microsd card not reconized from 2 month's now , so i just buy a scredriver and open it and what i saw freeze my blood : (

there is a pin from the mother board mSD card reader who is not there, it's really small like 1mm.

i can manage numerous things but this is a tiny soldering or i can use glue , the problem is ;

i do not have the pro materials for this ,so i was thinking of much of solutions and you tell me !

1- replace the motherboard ! it need 70€, is the mother board patchable ,idk !?

2- can i use a nintendo switch without a mSD card (just usb perhaps) ,idk !?

3-the conector reader in the mother board is conected with biggers one's (yellow rectangle) : can i wire those points and make my own mSDreader , i dont mind put the switch in a horrible estetic way if i manage to get it working

3a- if this solution above is doable ,what pin/point of the mother board GO where in the micro sd card ?

4- do i just glue a 1mm wire (i have it) in the place of the missing pin ?

5- what this pin do/transfer ? because the switch do not reconize the sd card without.
in hekate a message in red appear and advice you to :
*failed to init sd card.
*make sire that it is inserted.
*or that sd reader is properly seated!

wich is normal at this point.

im on 8.1.0 ofw with atmosphere 8.x.x and hekate 4.10.x. but i think this does'nt matter.

i need any suggestions even the bizzare one's cuz i do not have any pro material like hot soldering....
thank you.

Your only options are

1. Get a new board
2. Solder the module using alternate points. Theres a diagram floating around here somewhere but I couldnt do it. Too tiny.

Yeah you can use the switch without it but no CFW

and thats why i hate opening the switch and having to remove the damn reader.
this stupid lego connector is so small and fragile and you don't see if you actually hit it when you put it back in and I always feel like it will break every time

it's really annoying yes,this switch was dropped a lot (childs) , but i think i kill this pin today when i clipse it 3 times ,then i figured out what the problem is.

but like a said the problem occurs like 2 months ago , desapear and re-appear.

Not only that one! A lot of the connectors inside it feels so brittle... the one holding the game cart slot is equally as bad and I manage to by mistake eject my card reader when I applied thermal paste to my Switch.

You could do that, even if you break it even more, you'll just have to buy a new SD reader module, which is no different from the situation you are in now.

Oh, I didn't realize it was on the motherboard, that makes things trickier. The connector can be replaced if you mess it up worse but it's not an easy replacement.
the trickiest part is not there , there is no pin/connector to replace ! idk where he go
i have some idea to wire the points in the yellow rectangle directly to the sd card reader , but for that i need a diagram to explain wich go where.

it's a 3.0.0 ofw switch with atmosphere , the lost is big ;)

edit : found the wiring schema ,i will try this out with prehistoric tool and see.

thanks to @mattytrog

finaly got it working, after the 2nd try ;)
it's a mess but the switch work again.
thank to the shema provided by @mattytrog in other thread.

i have never done this kind of tiny soldering before ,i was afread of loosing a my switch , but i got it working in 20mn from the switch unscrew to the happy final.

the switch was running (hekate) from the begining , i know it's not the normal procedure but i set it like that to test it really quick.

like i said before ,only with basic materials you can do it ;)

some photos :

Hi I think I have the same problem but 3 connectors are missing.
Shall I have to replace the motherboard or shall I have to add 3 wires?

Unfortunately I cannot post the picture until I post 5 messages :sad:

hi , you can post a raw link to your image ,with image hosting sites.

- if you replace the motherboard you will have perhaps apatched unit , unless you are sure it's good for CFW.

- you dont want to use a cfw ,hombrews & cie ,then you can replace it , cost you some money.

- you can solder the missing wires , i see here some guys do it ( skilled and not skilled with soldering ) including me ,who managed to get it working , unless you have parkinson syndrome, you can do it imho.

there is a more specific shema here :
https://gbatemp.net/threads/about-the-microsd-card-connector.523130/

je suis sur que tu peux le faire , un peut de patience et ne met pas trop d'ettain et ça le fera.

Thanks for your support Mitcha
Find below the picture of the 3 missing contacts

--------------------- MERGED ---------------------------

I bought a soldering tool this morning and after 2 hours of fighting with the SD card reader. The result is not good enough :angry::angry:
I don't think I will succed in the soldering on the switch :sad::(

So 2 choice for me :
- Buynig a new mother board (replacment seems much more difficult than changing the SD card reader)
- Buying a new Switch (will it be OK with my SX Pro?)

That's a huge wire for such a small connection looks like you're nearly bridging to the next pin over when its installed, not sure though, I'd highly suggest trying to find a smaller wire to do the jump, I mean it will probably work for now, and may work long term but I'd be nervous about it personally.

Edit: Ah I see, its not really close, just a big wire, zoomed in it looks like it will probably be ok, looks like the solder blob on the pin is also looks pretty big.

Some news about my problem. I found a professionnal in order to make the connections with soldering wires. He does the job for 50€ and now the switch crack works again.

Thanks all for your help and your support.
