2.3 Security Patches and Android Updates

If your device runs Android (usually Android 8–10 based on the MT5510 era), updated firmware may include security patches, though many vendors stop support. However, custom builds of Tp.mt5510s.pb803 may offer GMS (Google Mobile Services) certification fixes.

Method 1: Android Settings (if device boots)

Go to Settings > About Tablet/Device.
Look for Build Number, Firmware Version, or Kernel Version.
If you see "tp.mt5510s.pb803_v1.2" or similar, you have the original firmware.

Prerequisites

Windows PC (Windows 10 or 11 recommended).
USB data cable (not a charge-only cable).
MediaTek USB VCOM drivers (download "MTK USB Driver" v1.0.8 or newer).
SP Flash Tool v5.2116 or later.
Backup of user data (if possible).

Method A: Flashing with SP Flash Tool (For completely non-booting devices)

Step 1: Install MediaTek Drivers

Disable driver signature enforcement on Windows (restart → Advanced startup → Disable driver signing).
Run MTK_USB_Driver_installer.exe as administrator.

Step 2: Extract Firmware Package

Use 7-Zip or WinRAR to extract the firmware zip.
Ensure the scatter.txt file is present in the extracted folder.

Step 3: Launch SP Flash Tool

Run flash_tool.exe as administrator.
Click Scatter-loading and select the scatter.txt file.

Step 4: Configure Options

Go to Options → Option → Download.
Check "DA DL All with Checksum" and "Storage Type" (eMMC for PB803 boards).
Uncheck "Preloader" unless you are certain it's corrupted (flashing preloader incorrectly hard-bricks the device).

Step 5: Connect the Device

Power off the device completely.
Hold Volume Up button (or sometimes the reset hole) and plug the USB cable into the PC.
SP Flash Tool should display a red progress bar (download agent loading).

Step 6: Start Flashing

Click the Download (green arrow) button.
The process will show purple (DA download), yellow (flash), and finally a green checkmark.
Do not disconnect during this 3–8 minute window.

Step 7: First Boot

Unplug the device and power it on.
The first boot may take 5–10 minutes (Android is rebuilding cache).

Q3: Where is the Android source code for this board?

MediaTek does not release GPL source for MT5510 publicly. You can request from your board’s distributor. For hobbyists, custom ROMs are not possible without the mediatek/config/mt5510/ kernel tree.
