I had numerous unexplained SMS and MMS related issues using OSK. Switching to the Lineage 20 GSI has fixed those and I can send and receive all SMS/MMS messages completely fine.

After two days and many hours of troublshooting, I have not only didnât make any progress, but successfully bricked my phone (canât get it connected to mtkclient and restore the backup). Man I give up.

Iâm also stuck here. When you say that you solved it by trying a few times more, what did you try?

I used fastboot flash vbmeta --slot=all vbmeta.img provided by Gemini. It allowed me to proceed. HOWEVER, after I flashed the Lineage OS (lineage-20.0-20251021-UNOFFICIAL-arm64_bgN-vndklite-signed.img ), wiped data, and rebooted the phone, I am stuck in the fastboot screen (white background with a line at the bottom). No matter what I tried, I couldnât boot into Lineage. Here is a chat with Gemini with all of my troubleshooting attempts, but none worked. Please let me know how it goes on Mac.
It would be fantastic if I could make this work, access to google services, and have a stable MMS.

Have you tried using the unsigned lineage gsi? This is just conjecture, I have very limited knowledge of the android boot integrity checks, but I think itâs possible since weâre not touching vbmeta_system, the gsi (system image) needs to be unsigned or it will trip an integrity check in the bootloader.
This is the specific rom I was able to get working; be advised, it is built with root privilege.

I just tried it, but it unfortunately still doesnât work. I think there is something systematically and fundamentally wrong with what I am doing, which is odd because I am doing the installation on a brand new phone.

As you can see above we both have the same issue: we follow all the steps to install GSI but in the end we land at the fastboot mode prompt (instead of booting to GSI). At this stage I am suspecting that there are different versions of the hardware and the steps above do not work for the newer ones. I got the phone about 2 months ago by the way.

I have read through this and am left wondering why someone would buy a specialized minimal phone and change the most fundamental part of it. I am not criticizing but genuinely want to know why.

I guess itâs to increase develoment flexibility for more tinkering for to make the phone better suit oneâs expectations with features that are not available in Mudita OS K.

If they wanted features that were not on the Kompakt, then why get it. It just seems they are destroying the whole concept of the phone. I just donât understand why by a minimalist phone and then try to make it into a fully featured smartphone?

Itâs not about turning it into a fully-featured phone. If you go across threads in this forum youâll see tiny quirks that people try to work around. Some built-in developer options do the trick, but not always. And some options are just not available.
2nd reason is Mudita OS K is based on AOSP 12 which is a bit old and there are security concerns being brought up.
Thirdly, itâs not just a minimalist phone, itâs a unique small e-ink device that someone may have an idea of using specific way because of the e-ink, not because of the minimalist paradigm.

Mudita markets it as a minimalist phone. Their product page lists them as minimalist phones. Part of the minimalism is e-ink. It all just seems strange to me, buying a minimalist phone to add apps that makes it no longer minimalist. I guess it is just me.

That depends entirely on what you mean by âminimalist.â You seem to assume that wanting a minimalist phone means having no need for anything beyond calls, texts, and a browser. That assumption doesnât hold for me.
What I want is a small-form-factor phone that actively discourages social media use and doom-scrolling, while still supporting essentials like banking apps and digital ID which both require gApps.
Whether that fits your personal definition of âminimalistâ is up to you. What matters is that the Mudita Kompakt running LineageOS meets my needs extremely well. It does everything I need, but itâs just inconvenient enough that I donât waste time on it. I only bought the Kompakt once it gained support for a GSI.

The phone is advertised as minimalist but nobody can stop you from doing with your property whatever you want. Same with drinking capuccino after noon, nobody is verifying that (unless youâre in Italy, ciao ragazzi 
).

I am not at all implying that they should be prevented from doing what they want with their property, I am just trying to understand why they they want to. It seems there are other devices out there that would better suit their needs out of the box⌠to each their own, I guess I tend to be more of a purist that way.

Please let us know which Compact phone is under 5 inches and has an e-ink display and allows me to communicate with my family via Signal or other contemporary apps that donât include the ancient unsecure SMS.
I would gladly appreciate, Iâm sure a lot of other people would love to know.
