Absolutely! This is totally a feasible approach—super handy for bulk app updates when you don’t have reliable network access or don’t want to mess with MDM tools. Let’s break down exactly how to pull this off:

Step 1: Prep Your USB Drive

Drop all your updated APKs into a dedicated folder on the USB drive (I recommend naming it something like APK_Updates to keep things organized, instead of cluttering the root directory)
Make sure your USB drive is formatted in a format Android supports: FAT32 or exFAT (NTFS can hit compatibility issues on some devices, so avoid it if possible)
Pro tip: Name each APK to match its package name (e.g., com.google.maps_11.2.0.apk)—this makes troubleshooting way easier if an update fails.

Step 2: Write the Update Script

Android uses the pm install command to install/update apps, so we can create a simple shell script to loop through all APKs on the drive and update them one by one.

Create a text file named update_apps.sh and paste this code:

#!/system/bin/sh

# Replace this with your USB drive's actual mount path
# To find it: plug in the drive, open a terminal, run `ls /storage` and look for a string like ABCD-1234
USB_MOUNT="/storage/ABCD-1234"
APK_DIR="$USB_MOUNT/APK_Updates"

# Check if the APK folder exists (aka USB is mounted)
if [ ! -d "$APK_DIR" ]; then
    echo "Error: USB drive not mounted or APK folder missing! Double-check the path."
    exit 1
fi

# Loop through every APK in the folder
for apk_file in "$APK_DIR"/*.apk; do
    # Skip if no APKs are found
    [ -e "$apk_file" ] || continue

    echo "Updating: $apk_file"
    # -r flag preserves app data during update
    pm install -r "$apk_file"

    # Verify if the update succeeded
    if [ $? -eq 0 ]; then
        echo "✅ Success! Updated $apk_file"
    else
        echo "❌ Failed to update $apk_file. Check if the APK is compatible with this device."
    fi
done

echo "All update attempts completed!"

Step 3: Set Up Permissions & Run the Script

Copy the update_apps.sh file into the APK_Updates folder on your USB drive.
Plug the USB drive into your Android device and wait for it to mount.
Open a terminal emulator (like Termux—you’ll need to install it from the Play Store if you don’t have one).
Navigate to the APK folder:
```
cd /storage/ABCD-1234/APK_Updates
```
(Replace ABCD-1234 with your actual drive’s mount name from ls /storage.)
Give the script executable permissions:
```
chmod +x update_apps.sh
```
Run the script:
```
./update_apps.sh
```

Important Notes

Root vs. Non-Root: If your device isn’t rooted, pm install can only update user-installed apps (not preloaded system apps). To update system apps, you’ll need root access or an APK signed with the system’s signature.
Mount Path Variations: Some devices might mount USB drives at /mnt/usb or /storage/usbdisk—run df in the terminal to see all mounted storage locations if you can’t find it under /storage.
User Confirmation: On non-rooted devices, you’ll get a pop-up asking to confirm each installation. If you’re rooted, you can add --user 0 to the pm install command to skip these prompts (use carefully!).
APK Compatibility: Make sure each APK matches your device’s architecture (arm64, x86, etc.)—mismatched APKs will fail to install.
