I cannot connect to wifi at all after rebuilding my nand with choidujour. I downgraded to 6.0 and thats when I noticed no signals appearing. Ive rebooted, factory reset, completely remade my cfw on my sd card. updated through a couple of versions to see if that maybe fixed something and finally, I put Android on another sd card and booted that up to see if the problem followed me and it did.
I am at a loss, Ive scoured the internet and havent found much of anything so any help would be appreciated.

So prior to the wifi problem I was stuck on the nintendo switch logo at boot while trying to boot both cfw or ofw. I let atmosphere update itself before that. Could that be at all related?

Congrats. It's the BCM chip. I have another switch with that problem. You can check the components around the BCM chip and replace them if they're broken

Before touching the hardware, check the router if the channel is not in manual, my Switch does not find wifi if it is in a channel above 11.

Yes. This was the only way I could get it to boot after I got stuck in boot the first time. I downgraded to 6.0 and that's when I found wifi not working.

I know it's not the channel on the router because I have 2 switches and the other one is fine and it was seeing wifi before the downgrade

Bluetooth is working fine.

Oh, if Bluetooth is working it's not the BCM4356.
Maybe the WiFi antennas?
Can you create a WiFi hotspot while running Android?

Nope. I think it gave me the option for sharing my internet via bluetooth though. I tried going through all the developer settings in android to test or at least interact in some way with the wlan but none of those were working either.

EDIT: Sorry im not trying to fragment my story lol. So after I downgraded from 9.1 to 6.1 and noticed the wifi not working I wanted to see if updating would do anything so I used choidujourNX to move up to 8.0 and that worked fine but didnt solve the wifi so I moved up again to 9.0 and I got stuck on switch logo again. rinse and repeat. It worked perfectly fine before I let atmo go and update itself because I was being lazy

Well... I have no idea what's wrong with it. If Bluetooth is working fine on Android it can't be the WiFi chip.
Can you use controllers in wireless mode?

Okay I loaded up Ubuntu on my switch to see if I could get any more control over the hardware but I guess it would help if I knew more about how to use Linux. I was able to find this though..

@jrandom which version of linux you used ?
Also you can try and run lspci -vvnn and look for the adapter, there you will be able to see if there any driven loaded for it, you can even reload the driver

  • TwoSpikedHands @ TwoSpikedHands:
    yall im torn... ive been hacking away at tales of phantasia GBA (the USA version) and have so many documents of reverse engineering i've done
  • TwoSpikedHands @ TwoSpikedHands:
    I just found out that the EU version is better in literally every way, better sound quality, better lighting, and there's even a patch someone made to make the text look nicer
  • TwoSpikedHands @ TwoSpikedHands:
    Do I restart now using what i've learned on the EU version since it's a better overall experience? or do I continue with the US version since that is what ive been using, and if someone decides to play my hack, it would most likely be that version?
  • Sicklyboy @ Sicklyboy:
    @TwoSpikedHands, I'll preface this with the fact that I know nothing about the game, but, I think it depends on what your goals are. Are you trying to make a definitive version of the game? You may want to refocus your efforts on the EU version then. Or, are you trying to make a better US version? In which case, the only way to make a better US version is to keep on plugging away at that one ;)
  • Sicklyboy @ Sicklyboy:
    I'm not familiar with the technicalities of the differences between the two versions, but I'm wondering if at least some of those differences are things that you could port over to the US version in your patch without having to include copyrighted assets from the EU version
  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
  • The Real Jdbye @ The Real Jdbye:
    @TwoSpikedHands just switch, all the knowledge you learned still applies and most of the code and assets should be the same anyway
  • The Real Jdbye @ The Real Jdbye:
    and realistically they wouldn't

    be able to play it legally anyway since they need a ROM and they probably don't have the means to dump it themselves
  • The Real Jdbye @ The Real Jdbye:
    why the shit does the shitbox randomly insert newlines in my messages
  • Veho @ Veho:
    It does that when I edit a post.
  • Veho @ Veho:
    It inserts a newline in a random spot.

    do y'all think having an sd card that has a write speed of 700kb/s is a bad idea?

  • The Real Jdbye @ The Real Jdbye:
    @Karma177 that sd card is 100% faulty so yes, its a bad idea
  • The Real Jdbye @ The Real Jdbye:
    even the slowest non-sdhc sd cards are a few MB/s
