Hello.

Recently i have installed picofly modchip on my switch oled. The installation went mostly fine, i had some alignment issues on the nand side but after realigning it, it showed good resistance values. The modchip boots instantly to picofly toolbox but if i try to boot hekate then it shows low battery symbol. I have tried unplugging the modchip, nintendo logo shows up but shortly after that low battery and it shuts down. I have checked the battery, the voltage is 4.167V and that is near full battery right ? What could be the issue since the battery indicator is completely wrong ?

I have remembered one more thing, after the installantion, battery percentage was higher and it was booting to no payload.bin detected but i did not create the sd card files instantly but later.

I recall there are 2 resistors/datalines near the CPU that are required for battery information communication.
If you get no battery information in Hekate then the traces or resistors might be damaged.

The official firmware requires a good battery to start.
Afaik this is some sort of safety measure as bad/depleted batteries can catch fire.

Do you maybe know where exactly are those resistors located ?

Maybe it could be fuel gauge chip ? It also tells battery status.

    @IC_, thats why i'm staying in Twitter
  • IC_ @ IC_:
    I haven't ever used either of them, besides viewing specific content while logged-out.
  • IC_ @ IC_:
    I am not sure what to think of Bluesky. Some people are overly positive about it, some are overly negative. It popped out of nowhere when seemingly everyone who dumped Twitter had already moved to Mastodon or similar federated services.
  • Xdqwerty @ Xdqwerty:
    @IC_, not liking/doing what everyone else likes/does sort of makes me feel bad
  • IC_ @ IC_:
    I still don't get what the deal with Bluesky is, I heard it was supposed to be federated and possible to self-host like Mastodon as well, but somehow I haven't seen or heard anyone doing that. Yet people complain about community and moderation issues on the official Bluesky instance. I really don't get what's going on and how it's supposed to work.
  • Xdqwerty @ Xdqwerty:
    @IC_, Yeah most of the posts I get are either about polítics or selfies and all that

    @IC_, although I just asked on the official subreddit if there is any feed(s) with the content I like
  • IC_ @ IC_:
    Myself, I have no interest in using (having an account on) such a social media website. People are often surprised that I don't have any social media and none of the most popular IM services, especially in real life. But I continue to stand against it, even when so many people have complained about it. Even if it makes my life a bit harder.

    I don't bother with social media.

    @anotherthing, being online is one of my few ways of entertainment since I will be murdered/kidnapped if I go outside while alone

    At some point I should probably create my own blog website, so my blogs can reach more people outside of GBAtemp. Long-form blogs are much nicer in my opinion compared to this modern "microblogging".
  • Xdqwerty @ Xdqwerty:
    @IC_, I ran out of ideas for blog entries and thus I just make profile posts
  • IC_ @ IC_:
    I still have lots of ideas, but it unfortunately does take a lot more effort to write a good blog entry with photos than to write a simple post.
  • IC_ @ IC_:
    Once I finish this project I've been working on for months, I'll hopefully do a blog entry about it.
  • Xdqwerty @ Xdqwerty:
    @IC_, I have been starting making a game, I will record a gameplay of the battle system once it's relatively done

    Haven't ever heard of it, but it could be interesting. Are you using RPGmaker for it, or something else?
  • Xdqwerty @ Xdqwerty:
    @IC_, gdevelop
  • IC_ @ IC_:
    Nice, it's open-source.
  • Xdqwerty @ Xdqwerty:
    @IC_, I only use "vanilla" gdevelop since I always forget how to code
  • Xdqwerty @ Xdqwerty:
    Also lemme show you a picture of how events work in it
  • IC_ @ IC_:
    I think free and open-source software is a very important benefit to everyone, even if you're not going to study or modify the code.
  • Xdqwerty @ Xdqwerty:
    @IC_, or well here is just the event tutorial itself https://wiki.gdevelop.io/gdevelop5/events/#timedelta
  • IC_ @ IC_:
    Yeah, I guess it's kind of like Scratch, a friendly programming interface. I think there was a specific term for this kind of thing, but I can't remember it.
