Hacking Help me with SafeA9LHInstaller and OTPless

[Aurora Wright]

So, as some of you might know, OTPless has very rare bricks occurring, this doesn't make it unsafe, but I'd like to get to the bottom of it anyway.
The reason must be random ARM9 memory and/or FCRAM corruption in the middle of the MCU reboot, but I have never had it happen myself, so I don't know which is corrupting and how often.
You can help me test this way: get the archive here: https://transfer.sh/15yTbC/tester.zip, copy arm9loaderhax.bin and the "test" folder on the root of the SD (don't use bootloaders), press SELECT and just wait. You won't see anything but it'll keep rebooting and checking that the memory doesn't corrupt, so there isn't any operation which might cause a brick.
The screens won't power on again until there's a failure, to prevent damage.
If it fails, send me the files in the test folder and tell me how many attempts it took for the failure (it'll be printed on screen).

Guess I'll try this on my N3DS
Will report with results later.

 

[CrispyYoshi]

I'll gladly help!... Are there any prerequisites for running this? How should we report our results back to you?

 

[DarkKaine]

Btw, Is it normal that all the LEDs go off? It's like my 3DS is fully powered down now.

edit: nvm its working now.. testing

 

[Windylacine]

is it for stock/A9LH 3DS? I'd like to test that for you.

 

[Aurora Wright]

You just need to have A9LH, o3ds or n3ds doesn't matter

Okay, great! How do you want us to report results, and where should we report them?

That's good, I'm downloading it right now and test that for you.

Simple question: If there's no errors or it doesn't fail, how will we know that it done it's thing??

It won't stop, run it until you feel like it

Ok, will give you my results later,

 

[DocKlokMan]

Started now. Will run until error, the 11th or Pokémon SuMo gets leaked, whichever occurs first.

 

[cravas]

Ok, first run for about 10mn and only thing I saw was the screens flickering on and off (the backlight) so I guess no errors.

New 3DS XL on 11.1.0-34E
A9LH/Luma3DS v6.3.1 stable
microSD card 32Gb Integral

Will run it for longer when I get my charger at home.

 

[Just3DS]

Testing on O3DS XL for more than 10 minutes now, but since the backlight for both screens are flickering on and off (probably due to A9LH v1 installed) I would be ending the test. No errors so far by the way.

 

[Aurora Wright]

Yeah I'm not sure if rebooting every few seconds with the screens turning on and off is okay to the screens. I'd recommend using this only with a recent a9lh which doesn't init the screens.

 

[DarkKaine]

omg.. do not run this software when you have screeninit a9lh installed.
my backlight is fucked now, it keeps flickering. goddamnit if i knew this i would have never done it.

I could see either backlight bleed or CRT-like ghosting within the LCD screen itself only on top screen's top-left corner, bottom-left corner and bottom-right corner, (making an oval dark shape in middle) so I'm getting worried. Sorry I couldn't help you test it.

Don't worry, it's a burn-in effect and it'll be gone after some screen-on time (leave it on a game or something).
Don't use this if you have a very old A9LH anyway.

 

[cravas]

Yeah, I've installed the screeninit version (when it was 5 part guide) since I have splashes on.

Will try it on some O3ds when I return home in a couple of weeks.

pull the battery for 10 mins my 3DS did this once and that solved it
