Debloated my AirNote4C to much

[BringerOfInk]

Hey Party people!

I made a mistake after rooting my AirNote 4C with removing bloatwear. I made an error in a script and remove all apps that have onyx in them with:

adb shell pm uninstall -k --user 0 NAME.OF.APP

I did create a backup on my live boot machine but forgot to copy it off. I do have the unpached `boot_a` and `boot_b` partitions backed up but I don't think the apps I deleted are part of the boot files. Now, the good news is I have a working rooted tablet but some things don't work. For example, when I try to change refresh setting the UI crashes.

I tried two things to restore the tablet (reset it)

1. I tried manually applying a firmware upgrade by downloading the latest `update.upx` and running:

adb shell am start -a onyx.settings.action.firmware

But I get (because the app is gone):

Starting: Intent { act=onyx.settings.action.firmware }
Error: Activity not started, unable to resolve Intent { act=onyx.settings.action.firmware flg=0x10000000 }

2. I tried the enter recovery mode by holding down the power button, waiting, releasing and the pressing it 5 times that I see floating arround but the tablet just keeps rebooting as long as I keep pressing it.

Now, the two fixes I can think of are:

1. I reflash the tablet with the stock firmware, but I don't know how to do that
2. Get someone to give me a copy of the `onyx.settings.action.firmware`. That should be enough for me to initiate a firmware update which might also restore the other apps.

Other ideas are welcomee

You're melting my mind. There is no AirNote4C, it's NoteAir4C.
It has the distinction of having 3 updates currently.

Well, if I were me, my idea would be to make a custom recovery and install an update from there.
That's a BSR device (isn't it?) and I've never been able to draw on those.
Isn't it time someone gave me one for my birthday?

On the other had, pm uninstall doesn't really do anything to system pre-installed apps besides setting some flags in data.
A wiping of user data should get you back.

Terribly sorry Renate! Brain melting was not on my todo list today! Thank you for the input. Seems like I panicked over nothing. If anyone does the same in the future you can just re-enable apps with:

cmd package install-existing PACKAGE.NAME

I re-installed all the apps I deleted with:

Enter shell:

adb shell

Re install apps:

cmd package install-existing com.onyx.easytransfer
cmd package install-existing com.onyx.voicerecorder
cmd package install-existing com.onyx.tscalibration
cmd package install-existing com.onyx.appmarket
cmd package install-existing com.onyx.kime
cmd package install-existing com.onyx.floatingbutton
cmd package install-existing com.onyx.calculator
cmd package install-existing com.onyx.musicplayer
cmd package install-existing com.onyx.latinime
cmd package install-existing com.onyx.android.note
cmd package install-existing com.onyx.android.onyxotaservice
cmd package install-existing com.onyx.aiassistant
cmd package install-existing com.onyx.kreader

Hello Renate,

You seem like a knowledgeable person, maybe you can advise me.
I rooted my NoteAir4C and now I want to unroot it and update firmware.
I am curently at 2024-11-21_14-51_4.0_8e3916db7, the normal way to update fails even after I have uninstalled magisk. I tried sideaload decrypted firmware 2025-07-26_19-00_4.1-rel_0726_509651412 with adb but it returns an error: Package is for source build 235 but expected 1649.
Do you know how I can update?

As I said above, I'd have to make a custom recovery for this.
