Software Minimalism: cleaning up Android how to delete pre installed (possibly unwanted) Apps – security warning

30.Oct.2023

security warning

“To protect against these attacks, Android users should avoid downloading APK files from obscure sources or publishers they don’t know and trust.”
https://www.bleepingcomputer.com/news/security/cybercrime-service-bypasses-android-security-to-install-malware/

https://m.gsmarena.com/samsung_galaxy_a5_(2017)-8494.php

“the ARMv8-A architecture added support for a 64-bit address space and 64-bit arithmetic with its new 32-bit fixed-length instruction set” (Wiki)

Just as Apple, Samsung and many other IT entities have never heard of “software minimalism” (aka UNIX KISS aka more is not always better)

also for data gathering purposes a sh*t load of pre-installed Android Apps are clogging up the system and it’s resources

How to get rid of them to give the device a notable performance boost?

WARNING: DO NOT DO THIS ON FOR-WORK-COMPANY-PHONES!

Because if the company get’s ransomeware hacked by a phone with outdated firmware… it’s LineageOS’ or Samsung’s fault, not the user’s.

Ideal solution: Install a custom rom

pro: the user will get a newer (hopefully more secure) version of Android than Samsung would allow 😀

WARNING! ALL FILES ON THE DEVICE WILL BE DELETED IN THE PROCESS!

FOLLOW INSTRUCTION STEP-BY-STEP CAREFULL!

(checkout xdaforum.com to find a good rom if there is no LineageOS available)

search it like this: https://duckduckgo.com/?t=ffab&q=xdaforum.com+A520F

where A520F is the Samsung Model Code <- this A5 even has an FM Radio when Headphones are connectd 😀 (IMHO VERY AWESOME and a SHAME that later models abandoned that)

https://wiki.lineageos.org/devices/a5y17lte/ -> possible to Update from Android 8.0 (default stock) to Android 11! NICE 😀

howto: https://wiki.lineageos.org/devices/a5y17lte/install

hostnamectl; # tested on
Operating System: Debian GNU/Linux 12 (bookworm) 
Kernel: Linux 6.1.0-13-amd64

su - root
apt install adb heimdall-flash

# get a GOOD QUALITY USB cable
# connect the phone and issue command:
heimdall print-pit
# if device reboots that indicates that Heimdall is installed and working properly
# it also spits out a ton of info: A5120F_print_pit.txt
# If it does NOT REBOOT: try a different USB cable or different USB port

# to get into "download" mode (allow to flash recovery mode)
# 1) power off device
# 2) disconnect USB cable
# 3) hold Volume Down + Home + Power

# almost immediately a cyan screen should show up

# continue with Volume Up key

# 4) connect USB cable

# then back to terminal
heimdall flash --RECOVERY recovery.img --no-reboot

# output
Heimdall v1.4.2

Releasing device interface...

# now trickiest part of the whole process:
# booting into LineageOS recovery.img
# 5) disconnect USB cable
# 5.2.) hold VOL DOWN + POWER until screen goes black, then release keys
# 5.1.) screen black: IMMEDIATELY hold VOL UP + POWER for 3 to 4 Sec

# if the user DOES NOT SEE LineageOS LOGO
# the user is in Samsung's recovery
# and need to re-flash recovery.img

# it worked? :D congratz! let's continue!

# tap Factory Reset, then Format data / factory reset


# on the android device tap "enable ADB" (it might be under "Advanced")

# back to terminal:

# the device should show up
adb devices
List of devices attached
5XXXXXXXXXXXXXX1 recovery

# on the android device tap "Apply Update" -> "Apply Update from ADB"


# back to terminal: # let's start the flashing :D
adb sideload lineage-18.1-20231014-nightly-a5y17lte-signed.zip
Total xfer: 1.00x

# let it sit for 15min

# now tap on "Reboot device"

# if it does this:

# DO 3 MIN OF DANCE-of-SUCCESS! :D

Second best solution:

find and uninstall as many “strange” apps as possible 😀

via GNU Linux:

Enable developer mode & USB Debugging:

Android: settings -> about phone -> software -> tap on Build 10x times to enable developer mode

Android: settings ->Developer Mode -> enable USB-Debugging & OEM-Unlocking

(checkout other settings that might be of interest)

man:

adb.shell.cmd.package.txt

adb.packagemanager.pm.txt <- this is the “interactive” package manager that is accessible after “adb shell” type “pm”

via GNU Windows:

no files will be deleted in the process: but it is a Windows program from an unknown vendor: https://adbappcontrol.com/

no root access is required: but BE CAREFUL ONLY DELETE ALL “*FACEBOOK*” because some Apps are REQUIRED for SYSTEM to WORK!

on the Android device go into settings -> about phone -> software informations -> tap on build number until developer mode is activated
- it asks for PIN for confirmation to unlock dev mode
on the Android device go into settings -> very bottom: Developer Mode -> somewhere in the middle: Debugging: enable USB debugging -> ENABLE
plug Android device into a Windows enabled PC with adbappcontrol.com software installed and running
unlock Android device screen (in locked state no access is allowed)
say “yes trust this device”
