Switch boots directly into RCM

Hey It's me again,

I bought another broken Switch on eBay these days and I'm trying to face the problem/s. So the console was in the mail today and like the seller described it doesn't turn on. I checked the Serial number on two websites, both claim it's unpatched. So I hooked it up to my Notebook to check if it's charging, it draws continous 0.45A which, in my opinion, is fine on a standard 5V outlet, whats more interesting is that immediately TegraRCMGUI popped up and said RCM OK!. So my next thoughts were "okay seems to be on auto rcm" but after trying to inject a payload it began to become strange, " Smashed the stack with a 0x0000 byte SETUP request!". Well isn't that a behaviour when the console is patched? I tried different PayLoads (BisKeyDump,Hekate...) but everytime it's the same 0x0000. So okay maybe this console is patched or even another mainboard inside that shell... But I'm curios whats triggering the RCM straight on boot, there is no JoyCon connected.

So my first question on this journey is: What can cause instant RCM on boot?

 

That would be worst case, hopefully it's something fixable

 

But if it's just AutoRCM it should accept Payloads from TegraRCM

 

Well well well, sounds like I should have stopped after my third repaired switch. I'll keep you posted

I think you are not correctly understanding whats the point, I can't turn off AutoRCM in Hekate cause the switch won't accept the Hekate payload (or any other) from TegraRCM

 

Are you serious, no one ever talked about a repair shop. Do you even read what I'm writing?

 

Also RCM itself isn't a 100% indicator for modding, it's just the point where modding starts. The RCM mode itself is some kind of recovery provided by Nvidia. I have to open the console to (hopefully) understand whats going on. Let's pray it's something easy, stupid and fixable. But the first signs aren't very satisfying...

 

The problem is, every emmc is married to the console, so if theres not the original emmc inside or it's broken, this switch can only be used for parts. I'm gonna open up the console the next days and check whats going on there. At the moment I can only be sure that it's charging correctly and it's pretty sure patched

 

I didn't pay a fortune but I also got cheaper ones before. But thats the risk you take when you're in electronics repair

 

Okay, this switch is unfixable. The pre owner pretended he didn't know if the console was opened up before... Long story short, no original thermal paste, the mainboard is for sure a patched one and last but not least the EMMC popped very easy of and has a slightly different color than the mainboard. So the best I could do is sell or use it for parts.
