Troubleshooting

Calls end as soon as they start​

The phone has signal and mobile data, but every call ends straight away, and Kompakt app → Diagnostics → Calls over 4G shows Registered No.

  1. Check the phone's region:

    adb shell getprop gsm.version.baseband

    If it ends in V236.P6, the phone is North American and needs the usa update package. Install it over what you have, from the recovery; no wipe is needed.

  2. Make sure the IMS app is installed and the phone restarted since: Calls over 4G.

Slow, apps without network, or the download manager crashes​

After installing over MuditaOS, or another LineageOS build, without formatting data. The old system's data is still there:

  • After MuditaOS, every app starts with its network access switched off, and the download manager crashes on MuditaOS's newer database.
  • After an older LineageOS build, such as Android 13, KompaktOS starts but runs very slowly.

Back up what you need, then in the recovery: Factory reset → Format data/factory reset, and install the package again. See Install.

The install stops with an error​

The download may be incomplete. Every release lists the md5 of each file; compare yours:

md5 -q KompaktOS-1.0-Global-GApps.zip                    # macOS
md5sum KompaktOS-1.0-Global-GApps.zip                    # Linux
certutil -hashfile KompaktOS-1.0-Global-GApps.zip MD5    # Windows

If it does not match, download the file again.

"Verify your PIN" after formatting data​

Setup asks for the screen lock the phone had before, or setting a new PIN fails with "Screen lock was already changed". That is Factory Reset Protection: the old lock is kept in a separate partition, frp, which formatting data does not touch. It only happens if the phone had a PIN or pattern before.

Erase it from the bootloader (fastbootd cannot reach it):

adb reboot bootloader
fastboot erase frp
fastboot reboot

Messages that are not errors​

Install completed with status 3. Installation aborted. in the recovery. You left Apply from ADB without sending a file. Nothing was installed and nothing is wrong.

No such file or directory from adb sideload or fastboot flash. The computer cannot find the file: it is not in the folder your terminal is in. Type the full path to it, or drag the file into the terminal window.
