chooj VS Loaders

If you're willing to dive deep into self-hosting, the open source chat protocol Matrix.org has support for an in-development iMessage bridge. Once you get it to work, there's a Matrix.org client on KaiOS devices called Chooj (sideloading guide) made by Farooq that you can use to access the chat.

I personally recommend going with a Matrix client and building a bridge to your Signal account.

My end goal is to sideload a matrix chat app on to my Nokia 6300 4G US phone. Root would be nice but I'm not sure it can be done.

We do have a third-party client for Matrix, the protocol technology which Beeper is based on. Check it out here, and you can sideload this app by following this guide.

Some guy started one here, but needs more support to keep it going.

Hmm, the Matrix.org client Chooj currently works, but only with basic functions, like one-to-one texting and calling, group/channel texting, experimental notifications and so on. It's just that the dev hasn't got time to work more on this - see the support chat at #chooj:mozilla.org. https://github.com/farooqkz/chooj

Though I am not aware of any developments on an xmpp client, farooqkz is working on a matrix client which could then be bridged over to xmpp

To root the US version I understand I'll need to go into EDL mode using a bin file (if there is one). Does anyone know how I can safely tell if I found the right file? this reddit post suggests there is one with a dead link. I found the file Here. The commit message for this file is "new loaders" and the only other reference I can find online to this file is on mobileread but I cant seem to find the post, just an attachment that isn't helpful. The site seems to be more for e-readers anyway so I'm not sure.
