N3DS 2 different colors please help

You updated a N3DS in safemode from 2.10, you're lucky you didn't brick. How in the hell did you even manage to fuck up?

 

enjoy getting a hardmod

 

Why? Not sure how updating from 2.1 would not brick his system on N3DS when it's known to be a guaranteed brick, so I somehow doubt he even did that while on 2.1 but instead at some other part. If his console works and if he can boot into D9 to restore a backup, then doing that would do exactly the same thing that a hardmod would.

What guide did you use? What part did you get black screens on? What FW are you on right now? Just because it's like that right now is irrelevant, because judging from your picture the console actually works. If it works, you should be able to start over. If you can get back to 2.1 and install A9LH, then restore your backup that weird problem should disappear as well. Keyword is: should

 

I guess, because of he said he booted with black acreen, he probably didnt even install a9lh

 

I encountered this when I was installing AL9H on my n3ds xl. Top screen flickers green and bottom screen was blue. It was quite difficult to read but I went ahead and followed the 3ds guide and once I reinstalled on NAND, the colours went back to normal.

 

You must have not read the guide.
From the guide:

Also from teh guide:

 

Important Question, Did you create a NAND backup before going 2.1?

 

Tell us the last step you did on the guide. Did you remember to remove the SD card when booting 2.1?
From the guide:

 

OK, did you go into safemode and stuck on updating process, but not finishing update it yet?

 

OK, that's answer why you didn't brick it yet.

 

If you didn't actually complete the system update then, power off your system, remove the SD card and power it back on. If you did do the system update then, you're bricked.

 

... yes it will.... this is directly from the guide

Do yourself a favor and read ever word on every page of the guide. EVERY WORD. EVERY WORD. EVERY DAMN WORD.
