open a command prompt and verify that ADB

functions: shell adb

If you get a ": / #", it works. If it says "error: no device / emulator found" does not work

If ADB works:

Open a new command prompt and type this command:

adb push HwCallRecorder / / system / app /

This assumes that the command prompt is open in the same folder as HwCallRecorder is (and HwCallRecorder is checked out), otherwise you will need to "cd" or place HwCallRecorder in the same folder as you have adb.

Switch to the command prompt with the adb shell in it.

Copy these commands one by one and paste the adb shell command prompt: (Ctrl + C then press the right mouse button to paste)

chmod -R 0755 / system / app / HwCallRecorder

chmod 0644 /system/app/HwCallRecorder/HwCallRecorder.apk

chmod 0644 /system/app/HwCallRecorder/oat/arm64/HwCallRecorder.odex

chmod 0644 /system/app/HwCallRecorder/oat/arm64/HwCallRecorder.vdex

At the end it is possible to restart the system.

aprire un prompt dei comandi e verificare che ADB

funzioni : shell adb

Se ottieni un ": / #", funziona. Se dice "errore: nessun dispositivo / emulatore trovato" non funziona

Se ADB funziona:

Apri un nuovo prompt dei comandi e digita questo comando:

adb push HwCallRecorder / / system / app /

Questo presuppone che il prompt dei comandi sia aperto nello stesso cartella come HwCallRecorder è (e HwCallRecorder è estratto), in caso contrario dovrai "cd" o posizionare HwCallRecorder nella stessa cartella che hai adb.

Passa al prompt dei comandi con la shell adb al suo interno.

Copia questi comandi uno per uno e incolla il prompt dei comandi di adb shell: (Ctrl + C quindi premi il tasto destro del mouse per incollare)

chmod -R 0755 / system / app / HwCallRecorder

chmod 0644 /system/app/HwCallRecorder/HwCallRecorder.apk

chmod 0644 /system/app/HwCallRecorder/oat/arm64/HwCallRecorder.odex

chmod 0644 /system/app/HwCallRecorder/oat/arm64/HwCallRecorder.vdex

Al termine è possibile riavviare il sistema.

Se adb non funziona, non c'è molto da fare: /

OTG non sembra funzionare (ancora) in questo TWRP. Può una volta che qualcuno ne costruisce una versione migliore.
