# BL-9000 Bloatware Uninstall
#
# Removes Blackview OEM bloatware and specified Google apps
# using `pm uninstall --user 0` (soft-remove, reversible via
# `pm install-existing --user 0 <pkg>`).  No reboots between
# packages — one optional reboot at the end.
#
# Usage:
#   ./batch3_bloatware_uninstall.sh [--list] [--reboot]
#
#   --list    Dry-run: show which packages would be removed.
#   --reboot  Reboot the phone after all removals.
#
# Device selection (pick one):
#   ADB_SERIAL=BL9000EEA0000102 ./batch3_bloatware_uninstall.sh
#   PHONE_IP=192.168.1.x        ./batch3_bloatware_uninstall.sh

# PACKAGES TO REMOVE
#
# All removed with `pm uninstall --user 0` — the APK stays in
# /system so a factory reset or `pm install-existing` restores
# it.  Safe to run even if a package is absent (skipped).
