SD card causing black screen...

If your saying you have placed the sd card in to the reader and tried a new and old card and it stops you booting, that could be a sign of a damaged sd reader port on the switch. Maybe time to replace it, may have gotten som sh&t in it and damaged the reader..

Try Format the card to exfat..

Also try placing in the old card with no files on it but the correct partition type , either fat 32 or exfat depending on your system...

If the blank card formatted correctly doesn't let you boot then you know its the reader( Prob a short )

 

Payload goes to the switch not the sd...

What i mean was, try blank sd to launch hekate, and see if it loads now..
.Hekate can launch without sd and or emmc)nand)module installed..
Also try another format rather then 32 try exfat or vs verse....

To be honest tho if its affecting the switch booting on bot sd cards, could be a faulty reader,
But like i said try a blank formatted sd card and launch hekate...

If that works its could be the files your putting on the sd card...

 

You can restore NAND with memloader and HacDiskMount from a PC. But it's not gonna fix your issue, as the issue occurs even in Hekate which is completely separate from NAND. It's likely a hardware issue.
The SD reader is on a separate board which slots into a connector on the mainboard, I've seen several cases where this connector was damaged, it could happen from something as simple as dropping the Switch if you have bad luck. It could also be bent pins in the SD slot itself if you've been rough when inserting or removing the MicroSD.

 

It could be the connector on the mainboard that's damaged. That won't be an easy fix unless you're good at soldering with a hot air station.

 

Yeah goodluck, im hoping its something as simple as the sd card reader...
The zif connector were the sd card reader meets the main board needs to be lined up correctly, and you should feel or hear a gentle Click,pop.. when connected correctly, i found to gently remove the foam pad sometimes helps locate and connect. Make sure to put the foam pad on the new one..And as always with Flexible Flat Ribbon Cable they can break easy so try not to bend them too much(Talking about the one on the sd reader board )

 

That sucks.
Whats your format method and what are you using to format the sd card ?...Let us know.

You say your having issues with two sd cards and also you replaced the sd card reader,
Im guessing your using the latest hekate so all i can say is your cards are not being formatted correctly .. or there is a more serious and deeper issue with the system

So Try a different format method, i never use windows own format method cause it never works correctly.

Use a app called SD CARD FORMATTER https://www.sdcard.org/downloads/formatter/

I like to use mini partition tool to format my stuff.
https://www.minitool.com/partition-manager/partition-wizard-home.html
Format to either Exfat cluster size 128kb
Or FAT 32

I think also if you remove all partitions, Volumes from sd card. you can place sd card into switch boot stock Ofw and it will format the sd card for you...

 

you dont have to disable AutoRCM..


Sd card is not required to launch, but is for say hekates config files.

Use hekate and launch stock. does it work ?
Whats your battery reading within hekate ? can u post .
Can you launch into OFW at all ? Problem may lie somewere else rather then SD card.
As switch doesn't need a sd card to boot ofw.

And switch doesnt need emmc module or sd to go into hekate.

Just had a thought, send the memloader payload to your switch and select SD Card option see if your sd card shows when u plug the switch into pc...

 

Format the sd card to Fat 32 and try again. please
And does the console boot into OFW without sd card inserted >?

 

Right so here goes,

Originally i thought you had said that OFW was working fine, that you can get in or to the nintendo main menu without a sd card in..

Now..
If you cant boot into OFW then sir you have bigger issues then a sd card..
The sd card and or reader maybe fine, but a bad diagnosis.

That said, its time to look at or fix nand.

Try something for me.
Remove SDcard.

And go into hekate and take screenshots or pics of the emmc information.
If it does not work. Then we need to look at the emmc module,
Could you be a little gentle and remove the EMMC module, check the pins on the zif socket.
and reseat it.. Do you get emmc info in hekate now ?

If not . Try this.

Use memloader payload but this time mount the EMMC

Then use Nx Nand manager or hacdiskmount. and see if you can load the pyhsical drive..

Im thinking now that you have Emmc issues,


Get as much info out of Hekate take pics and post, also same with memloader and or any errors you get along the way.

If you cant boot ofw, then you def have hardware short,failure or corrupt emmc or dead emmc, il say it how it is..
You was playing a game and it froze, now you cant boot ofw and your getting Weirds emmc or sd issues, Im hoping you didnt overheat and cause a cold solder joint..

I dont mean to scare ya or think oh ffs. But we need to look at nand now..
If your able to restore or not or even boot into OFW should be our first step.
You say you have a backup,? Did you backup boot0 boot1 and your system keys ?
You should.we may need those.

Also thinking about it, try sending the LockpickRCM payload also, with sd card in. See if you can dump keys Without getting errors of unable to read package 1/2 etc..

Report back. Hope i made some sence..
