Hello!

Iam working on a Nintendo switch V1 unpatched and would appreciate some help.

When I got the device it was in RCM mode and there was something wrong with the firmware, did a rebuild and got it working! The USB-C port was damaged so I installed a new one. After the installation of the new USB-C port it didn't boot, didn't touch anything else on the device. I tried rebuilding the emmc one more time, but this didn't help. I can boot Hekate, but get a fatal error when I boot CFW and a black screen on OFW.

To my understanding the device boot on a first stage, but something prevents it booting into second level stage.

Installed Android to rule out a bad emmc (Because Android boot from the SD-card) but Android installs just fine but I get a error message when booting into Android.

In Hekate under HW info the SKU is in a orange text, does this means that the CPU is dead?

Sorry for this long description, but I really need some assistance😁

You probably meant the emmc.
Just my assumption, likely Hekate pulls the SKU information somewhere from the emmc.

Sometimes the emmc connector goes bad over time.
Just opening to do a repair is enough to make the emmc stop working.
If you emmc is fine, you should see something like this in Hekate.

If you get an error message that the emmc is running in 1-bit mode, then there is something wrong with the connector.
You could try pressing the location of the connector down gently while booting.
Sometimes, people press on the emmc board with too much force and then pins bend or break.

Hekate boots without anything from the emmc.
The BOOT0 and BOOT1 partition should be valid in order to both the CFW/OFW.
BOOT0 and BOOT1 are not encoded specificly for each Switch.
If they are corrupt and you need to repair them, just make sure you have the BOOT0/BOOT1 for the same model.

Thanks for your reply! Okey, so that the text is orange ain't a way to diagnos the hardware? I can see that the DRAM ID on the same page is in orange.....

So you think the fault has something to do with emmc? I have a spare emmc laying around, I will try to rebuild that one and see if that makes a difference.
 
Have had some to check the switch again, did check that page and it looks like it's okey.... But this is the information I get from Hekate, is there anything in this information that tells me what's wrong with the device?

Using a pc, look on the micro sd card: Atmosphere/ Contents and delete the "010000000000000005" folder, reinsert SD card into Switch and reboot.

Thanks for the reply! Have done just that, didn't find a folder with that name. But I tried delete all the content

Update your overlay files?

Sorry, but tried that too...... Tried booting with different versions of atmosphere but with the same results. Booting to OFW it gets stuck on black screen, it pulls 15v and 0.5 amp. I know that the screen works and the battery charges, I can see all this inside of Hekate. Would be great if I could load some payload in Hekate to find is there is something wrong with the hardware......

This is what I did the first time, and this resulted in a functional Switch! But after a USB c port change I get this problem. Tried rebuilding a second time with no luck

I have tried the device with two batteries and changes the Fuel Gauge two times, but it still does not boot. Tried installing Ubuntu but even this freeze at the first screen, the same as Android. Seems like something is preventing this switch to boot......

Tried using Biskeydumpv9 and get this information:

How can I troubleshoot what part of the hardware that prevents it from booting anything other than Hekate?

Same here...... Have you tried to rebuild your emmc? Do you have the same result as I have?

Black screen on OFW and fatal error on CFW?

also if you updated the OFW offically then your sdcard might need to be reformatted to fat32

maybe try this aswell

Hello,

Random question but does anyone know the value of these resistors next to the DRAM on a V2 switch?

This might sound silly, but if you haven't figured this out yet, have you tried removing the USB port and boot without it? Don't just remove it, but also wick off the solder to clean all pads. Takes seconds to re-tin them if nothing changes and you want to put it back on.

But while it's off... I'd also look carefully for shorts, splatter, etc. If it still does not boot with it off, you might also go fishing for a shorted cap (in diode mode, only 1 end should beep on ground...)

I think is something about the capacity design of the battery
