Uninstalling Preinstalled Android Apps without root

Uninstalling Preinstalled Android Apps without root

On my Moto G6 every Update seems to re-enable the Outlook and linked-in in apps I disabled on purpose. You can not uninstall apps that have been installed by the manufacturer via the play store or app settings, only disable them.

So far I have been disabling them after each update but I have gotten quite annoyed by it and did a little bit of research to find out how to fully uninstall them.

Prerequisites

What you need is the Android Developer Bridge (ADB) on your computer and you need to enable USB debugging on the phone.

I have used Windows in this guide but there is a great guide on how to set everything up in Windows, Mac & Linux over at XDA-Developers that walks you through the process.

USB Debugging on the Phone

If you haven’t enabled the Developer Mode on your phone yet, you have to navigate to Settings, then System -> About and scroll down to the buid number. Tap this 7 times to enable Developer mode.

Then You will find the Developer Settings in the Systems Settings menu. Go there and enable USB debugging.

ADB on Windows

Setting up ADB on Windows is straight forward. Download the latest ADB version, extract the files in the zip and navigate in Powershell to the extracted folder.

Tipp: You can hold down SHIFT when right-clicking in Explorer and use “Open Powershell here”

From here you can run the adb commands. Since we did not add the folder to the PATH we will have to preface the command with .\ to make it use the adb.exe in this folder.

If you follow this guide on a different OS or have ADB in your PATH you don’t have to use the .\

Connecting the Phone

Connect the phone via USB and double check that USB debugging is enabled.

Then you check for connected devices

.\adb devices             

                    

This starts up the ADB service and lists connected devices

* daemon not running; starting now at tcp:5037

* daemon started successfully

List of devices attached

ZY322XXXX      unauthorized

On your phone you should get a pop-up asking you to confirm the ADB connection to the computer. After accepting it

.\adb devices                                 

Should list your device now not as unauthorized anymore.

List of devices attached

ZY322XXXX      device

Listing the Apps

.\adb shell pm list packages

Prints out a long list of all installed apps. You can use this list to find the full name of the apps you want to uninstall.

...

package:com.google.android.apps.inputmethod.zhuyin

package:com.microsoft.office.outlook

package:com.google.zxing.client.android

package:com.qualcomm.qti.dynamicddsservice

package:com.google.android.setupwizard

package:eu.siacs.conversations.legacy

package:com.qualcomm.qcrilmsgtunnel

...

package:com.keylesspalace.tusky

package:com.motorola.msimsettings

package:com.android.bookmarkprovider

package:com.linkedin.android

package:com.android.settings

package:com.motorola.arselfie

package:com.qualcomm.qti.lpa

package:com.qualcomm.qti.uim

package:com.google.android.inputmethod.pinyin

...

While you can uninstall most apps like linkedin and outlook you should be more careful with system apps.

Uninstalling the App

.\adb shell pm uninstall --user 0 [Package Name]

Will uninstall the app. So in my case I just had to issue

.\adb shell pm uninstall --user 0 com.microsoft.office.outlook

and

.\adb shell pm uninstall --user 0 com.linkedin.android

Once ADB returns with Success you can unplug your device and are done.

Remember to disable USB Debugging again in your Developer Settings.

Backup dei server Windows con rsync

Anche per gli utenti Windows, il tool rsync è un’alternativa interessante e conveniente rispetto ai costosi software di backup.
Per poter utilizzare questo protocollo, dovete però installare Cygwin.
Con l’aiuto di questa distribuzione simile a Linux si possono utilizzare anche sui sistemi operativi Windows diversi programmi Linux.

Procedete così per l’installazione:
Scaricate Cygwin al seguente link: cygwin.com/index.html.
Aprite il pacchetto, scegliete i moduli “rsync” e “openssh” e installateli.
Create un collegamento nello start menu o sul desktop.

Aprite il terminale di Cygwin tramite il collegamento creato e iniziate la configurazione SSH tramite il comando:

 ssh-host-config

(possibile solo se si esegue il programma come amministratore, cliccando con il tasto destro del mouse) Rispondete alle prime domande con “yes” e alla domanda “Do you want to use a different name?” (Volete scegliere un altro nome?) con “no”.

Infine, create un nuovo account, inserendo sempre “yes”, e scegliete la vostra password personale. Avviate il servizio SSH con l’immissione del comando:

 net start sshd

In questo modo, la configurazione della sincronizzazione crittografata con rsync è impostata su Windows e il servizio può essere utilizzato tramite il terminale di Cygwin, grazie ai comandi conosciuti di Linux. Qui bisogna però prestare attenzione ai tipici percorsi di Windows, oltre che agli utenti e ai gruppi.

TUTORIAL: PHP selector for PHP 5.6, 7.0, 7.1, 7.2, 7.3 for Debian and Ubuntu (and optionally directly nginx-PHP-FPM)

Posted: Fri Jun 15, 2018 11:28 am

This tutorial will enable PHP 5.6, 7.0, 7.1, 7.2 and 7.3 to specific/desired domains.

Tutorial is for Debian and Ubuntu (but probably can give you a good direction for CentOS).

PHP will run through PHP-FPM, which is much more faster solution than other existent PHP-switcher that uses only old phpfcgid solution (because with PHP-FPM you can use opcache).

Communication to PHP-FPM will goes through Unix-sockets, which is also the fastest communication between daemons.

Second tutorial goes a step forward - it will allow you to make direct communication from nginx to PHP-FPM, avoiding Apache for desired domains (Apache is installed by default in default Vesta installation).

So, yes, you can easily make nginx <-> PHP-FPM stack even if you have Apache installed.

And yet better news - you can use it only on desired domains - so all other domains will stay untouched.

First pre-required step for Debian 9:

apt-get update
apt install apt-transport-https ca-certificates
wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
sh -c 'echo "deb https://packages.sury.org/php/ stretch main" > /etc/apt/sources.list.d/php.list'

First pre-required step for Debian 8:

apt-get update
apt install apt-transport-https ca-certificates
wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
sh -c 'echo "deb https://packages.sury.org/php/ jessie main" > /etc/apt/sources.list.d/php.list'

First pre-required step for Ubuntu:

apt-get update
apt install apt-transport-https ca-certificates
wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg

Then in your browser go to https://launchpad.net/~ondrej/+archive/ubuntu/php/
Under Adding this PPA to your system click Technical details about this PPA, select your Ubuntu version, and two lines that you get from field box below add to /etc/apt/sources.list.d/php.list

Second pre-required step for both Debian and Ubuntu:

apt-get update
a2enmod proxy_fcgi setenvif

For custom PHP CMS:

wget https://raw.githubusercontent.com/serghey-rodin/vesta/master/install/debian/9/templates/web/nginx/php-fpm/default.tpl -O /usr/local/vesta/data/templates/web/nginx/PHP-FPM-72.tpl

sed -i "s#/var/log/nginx/#/var/log/%web_system%/#g" /usr/local/vesta/data/templates/web/nginx/PHP-FPM-72.stpl

For WordPress:

wget https://raw.githubusercontent.com/serghey-rodin/vesta/master/install/debian/9/templates/web/nginx/php-fpm/wordpress2.tpl -O /usr/local/vesta/data/templates/web/nginx/PHP-FPM-72-Wordpress.tpl
wget https://raw.githubusercontent.com/serghey-rodin/vesta/master/install/debian/9/templates/web/nginx/php-fpm/wordpress2.stpl -O /usr/local/vesta/data/templates/web/nginx/PHP-FPM-72-Wordpress.stpl
wget http://dl.mycity.tech/vesta/php-fpm-tpl/PHP-FPM-72.sh -O /usr/local/vesta/data/templates/web/nginx/PHP-FPM-72-Wordpress.sh
chmod a+x /usr/local/vesta/data/templates/web/nginx/PHP-FPM-72-Wordpress.sh
sed -i "s#%web_port%#%proxy_port%#g" /usr/local/vesta/data/templates/web/nginx/PHP-FPM-72-Wordpress.tpl
sed -i "s#%web_ssl_port%#%proxy_ssl_port%#g" /usr/local/vesta/data/templates/web/nginx/PHP-FPM-72-Wordpress.stpl

sed -i "s#/var/log/nginx/#/var/log/%web_system%/#g" /usr/local/vesta/data/templates/web/nginx/PHP-FPM-72-Wordpress.stpl

This way you can adapt any other existent Vesta PHP-FPM template for other CMS.
(list of CMS templates is here - https://github.com/serghey-rodin/vesta/ ... nx/php-fpm )

This is example for PHP 7.2.
You can install templates for other PHP version the same way, just substitute 7.2 and 72 with desired version.

Now simply go to Vesta, edit WEB for desired domain and choose:

Abilitare l'interpretazione del file .HTACCESS per APACHE su Linux

Sul proprio server abilitare il MOD_REWRITE

# a2enmod rewrite

Editare il file di configurazione di Apache, nel nostro caso nella directory /etc/apache2/sites-available/ aggiungendo dentro la direttiva <Directory...> le righe

AllowOverride all
Options all

Riavviare il servizio apache

VPN configurazione su UBUNTU e connessione con WINDOWS

Installa il server VPN PPDPT su linux

Su ubuntu

apt install pptpd

Modifica il file di configurazione /etc/pptpd.conf aggiungendo le seguenti voci

localip 192.168.1.156
remoteip 192.168.1.157-200

dove localip è l'ip del server vpn mentre il remoteip sono gli ip assegnati ai client

Modifica il file /etc/ppp/pptpd-options aggiungendo le voci

ms-dns 192.168.1.1
nobsdcomp
noipx
mtu 1490
mru 1490

dove ms-dns è il dns comune che si vorrà utilizzare

Modifica il file /etc/ppp/chap-secrets aggiungendo gli utenti e le password per l'autenticazione all'accesso. le voci dovranno essere separate da un TAB

# client        server  secret                  IP addresses
pippo    *       passworddipippo  *

Ravviare il daemon con /etc/init.d/pptpd restart

Cosa importante, aprire le seguenti porte TCP sul router: 1723 TCP, 47 TCP

Connessione su windows:

• Configura nuova connessione di rete
• Connessione a rete aziendale
• Usa connessione internet esistente VPN
• Inserisci ip pubblico del server linux VPN

Conversione e migrazione file di posta Outlook PST in thunderbird

La comoda utility "readpst" su linux permette di convertire i files .PST nel formato .EML importabile in thunderbird con il plugin "ImportExportTools"

Per usare il comando readpst in windows basterà installare e usare il programma "CYGWIN Terminal"

cd /home/user/Downloads
mkdir outlook
mkdir archive
readpst -o ./outlook -M -u -w -e -b outlook.pst
readpst -o ./archive -M -u -w -e -b archive.pst

Linux CHMOD solo su cartelle oppure solo su files

Ecco una risoluzione che può tornare utile.

Mi trovo con la necessità di resettare le permission di un Wordpress che come noto ha le directories in 755 ed i files a 644.
In FTP la cosa diventa lunga e con accesso da terminale possiamo usare:

find /path/to/base/dir -type d -exec chmod 755 {} +
find /path/to/base/dir -type f -exec chmod 644 {} +

Ubuntu Remote Desktop VNC XRDP

Velocissima soluzione per connetterti al tuo server linux in modalità grafica con VNC.
Il desktop grafico scelto per il server è "XFCE" molto leggero e veloce, non mi serve altro!
Aprire il terminale e installare i seguenti pacchetti:

sudo apt-get install -y xfce4 tightvncserver xrdp

Creare il file di configurazione

cat > ~/.vnc/xstartup <<EOF
#!/bin/sh
startxfce4 &
EOF
chmod +x ~/.vnc/xstartup

Avviare il server VNC

vncserver

Per fermarlo

vncserver -kill :<numero sessione>

Le porte da aprire per accesso con ip pubblico variano dal numero di sessione aperta.
Es. sessione 1 porta tcp 5901, sessione 2 porta tcp 5902, ecc...

Vedere elenco cartelle condivise e a disposizione su un server SMB

Uso il comando smbclient

# smbclient -L <server> -Uusername

sshpass, per inserire password dentro script di comandi

Poco sicuro ma efficace, mi è tornato utile per effettuare una serie di rsync temporanei senza attendere l'esecuzione degli stessi per inserire la password di accesso successiva.

Installazione e uso

# apt install sshpass
# sshpass -p <password> rsync -av --delete   user@ip:/directory   /mnt/drive

Streaming webcam con MOTION (ubuntu 14)

Streaming USB webcam su browser con MOTION su Ubuntu 14.04

Procedura per installare MOTION su Ubuntu visto la necessità di avere una webcam di videosorveglianza

sudo apt-get install motion

Modifica il file di configurazione situato in /etc/default/motion con la seguente impostazione

start_motion_daemon=yes

Linux eseguire procedure con comando SCREEN

Il comando screen in linux permette di eseguire procedure lunghe come trasferimenti da terminali remoti senza dover necessariamente tenere aperta la shell.

Installare screen con: 

# apt-get install screen

Aprire il terminale (putty) ed eseguire un qualsiasi comando, come ad esempio un rsync, con il comando screen

# screen rsync -av /sorgente /destinazione

Ora chiudendo il terminale putty dalla "X" l'esecuzione del comando rsync non verrà interrotta ma proseguirà fino alla conclusione naturale.

In caso di verifica basterà riaprire il terminale putty e dopo il login eseguire

# screen -r

Script in PHP per cancellazione di files

Ho trovato questo script in php molto utile per la cancellazione di intere directory e contenuti, cosa che molto spesso capita di fare e che molto spesso non ci si riesce a causa di crash continui o blocchi del client ftp di turno.

Indicare a fine listato la directory da rimuovere: remove('it/');

Script:

 <?php

function remove($dirname = '.')
{
        if (is_dir($dirname))
        {
                echo "$dirname is a directory.<br />";

                if ($handle = @opendir($dirname))
                {
                        while (($file = readdir($handle)) !== false)
                        {
                                if ($file != "." && $file != "..")
                                {
                                        echo "$file<br />";

                                        $fullpath = $dirname . '/' . $file;

                                        if (is_dir($fullpath))
                                        {
                                                remove($fullpath);
                                                @rmdir($fullpath);
                                        }
                                        else
                                        {
                                                @unlink($fullpath);
                                        }
                                }
                        }
                        closedir($handle);
                }
        }
}

remove('it/'); // Questa e' la directory che verrà svuotata.

?>

Accedere in SSH senza effettuare sempre il LOGIN

Per accedere ad una macchina tramite SSH senza dover tutte le volte digitare la password bisogna generare una chiave da posizionare nella directory utente\.ssh

- generare la chiave
[utente@linuxbox1 ~]$ ssh-keygen -b 2048 -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/utente/.ssh/id_rsa):
Created directory '/home/utente/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/utente/.ssh/id_rsa.
Your public key has been saved in /home/utente/.ssh/id_rsa.pub.
The key fingerprint is:
90:98:4f:f5:69:39:57:5d:46:83:a4:a2:d6:63:3c:25

 A questo punto dovremmo copiare la chiave pubblica sul server SSH. Questa essendo pubblica può essere letta da chiunque, senza problemi di sicurezza. Per copiarla possiamo usare anche scp, programma per la copia di SSH. Ipotizzando che il server si chiami linuxbox2 e che l’utente si chiami utente2, il comando sarà:

[utente@linuxbox1 ~]$ scp /home/utente/.ssh/id_rsa.pub utente2@linuxbox2:.

Ci verrà chiesta la password di utente2 e il file id_rsa.pub, contenente la chiave pubblica, verrà copiata nella home di utente2 su linuxbox2. A questo punto facciamo il login su linuxbox2 (ovviamente come utente2), e copiamo il contenuto del file appena copiato nel file /home/utente2/.ssh/authorized_keys:

cat /home/utente2/id_rsa.pub >> /home/utente2/.ssh/authorized_keys

A questo punto basterà provare a collegarsi dall’host linuxbox1 su linuxbox2 per connettersi a patto di inserire la passphrase scelta (per quanto sconsigliabile questa può anche non essere inserita, a patto di creare una coppia di chiavi con passphrase vuota):

ssh utente2@linuxbox2
