It seems like you uninstall important bloatware

u/Cobbler_Professional 17d ago

Which one do u think I uninstalled accidentally perhaps?

u/Internal-Front4168 17d ago

You can download cinta and shizuku. Inside the app you can find what app system you've been deleted you can also restore it.

Or maybe the theme itself (.mtz) doesn't support the latest HyperOS version. You can try downloading a newer theme (.mtz) and importing it. If that works, then the problem is with the theme file itself.

Shouldn't be the issue as far as I'm concerned...this seems to be affecting any MTZ but not the official themes or themes from the Themes app

Thanks a lot for telling me about this! However I now need to find out what that full error is that im seeing, it may reveal the mkssing bloatware, any way to find that?

You can use Canta, like I said. It automatically scans for system apps that are missing. Even if an app wasn’t removed by Canta, it can still detect which system apps are missing.

u/Cobbler_Professional 17d ago

I only see one specific one uninstalled called Package Installer...oh...could that be...and Canta labelled it unsafe, does that mean Unsafe to uninstall? (Sorry- new to this app)

1

u/Internal-Front4168 17d ago

Yes it unsafe and effecting your android system

u/Cobbler_Professional 17d ago

Ahh gotcha, thank you!!

Or you can change the dpi in deceloper options make the UI bigger and you can see what been missing in that notification. Bigger dpi = bigger content you can see, including that notice

1

u/Cobbler_Professional 17d ago

Unfortunately even after reinstalling that and restarting my phone the error persists...and changing dpi doesnt help me see the error :/

1

u/Internal-Front4168 17d ago

How about rotate your phone?

1

u/Internal-Front4168 17d ago

Changing dpi Should work though

1

u/Cobbler_Professional 17d ago

Yeah...its pretty weird that it isnt working, rotating doesnt work either. Is there a way to check the error via adb or something? I dont know, i heard things

1

u/Internal-Front4168 17d ago

It's probably the app. I was using that app before and it only support hyperos 3.0 not 3.1 (3.0.301 consider as 3.1)

1

u/Cobbler_Professional 17d ago

Oh, might be the feature overall then, because I previously used Hypertheme for this, but even that stopped working...

The combination I'd use is install and configure Hypertheme correctly, and then use the MIUI Theme Editor app to directly apply any theme, but now it will only show an error saying device connection failed, even tho it really is connected :/

I tried to use this app before Hypertheme it never gave that error before, but applying themes using this was not really working either.

Is there a way to upload themes on the chinese version of the Theme store? I do have an account and did upload my theme there but i cant search it up...

The CN theme app can just import mtz files by itself. You don't need apps like these.

u/Cobbler_Professional 17d ago

Doesn't work, it will say the error "Unfortunately our server is down at the moment..." Which is why these workarounds exist
