Download DTB Modifier Simple Tool | To Modify GPU Voltage From DTB For Qualcomm | 2024
This guide will walk you through modifying the GPU voltage in the kernel Device Tree Blob (DTB) of Qualcomm Xiaolong devices, verified specifically on the Xiaolong 870. Although this tool should theoretically work on other System on Chips (SoCs) with similar DTB file structures, users must confirm compatibility. Be cautious with voltage modifications as incorrect settings can cause issues. The user assumes all responsibility for any consequences.
Introduction:
Modifying GPU voltage can be useful for reducing heat and extending battery life on your Android phone. However, incorrect modifications can lead to problems, so follow these instructions carefully. Ensure your device is compatible and take precautions to back up your files before starting.
How to Use the Tool?
Step 1: Extract the DTB File
- Unlock Your Phone: Ensure your phone is unlocked and has a third-party TWRP (Team Win Recovery Project) installed.
- Extract the DTB File: Obtain the DTB file from your current kernel. Do not mix files from different kernels, as this can lead to errors.
Step 2: Modify the Voltage
- Open the DTB File: Use the tool to open the DTB file.
- Edit the Voltage: Modify the voltage values. You can change either the hexadecimal or decimal representation; the other will update automatically.
- Repeat for Frequencies: Ensure you modify all instances of the same frequency to ensure your changes take effect.
Step 3: Verify Modifications
- Compare Files: Use tools like Beyond Compare to check that only the voltage parts of the DTB file were modified.
- Check Consistency: Make sure the changes are consistent throughout the file.
Step 4: Replace the DTB File
- Backup the Original File: Always keep a backup of the original DTB file.
- Rename the Modified File: Rename your modified file to match the original DTB file name.
- Replace in Flash Package: Insert the modified file back into the firmware flash package.
Step 5: Flash the Firmware
- Use Recovery Mode: Use TWRP or another recovery tool to flash the modified firmware package onto your device.
Q&A Section
Why modify the DTB file?
- Purpose: Adjusting GPU voltage can help reduce heat and extend battery life. However, reducing the voltage too much might cause system instability.
Why not change the GPU frequency?
- Consistency: The frequencies must match those specified in the kernel. Mismatched frequencies can prevent your device from booting.
Why not decompile DTB to DTS?
- Safety: Directly modifying the binary DTB file is safer and results in fewer differences from the original, minimizing the risk of errors.
How to verify voltage modification?
- Testing: To confirm your changes, significantly reduce the voltage of a specific frequency and check for instability during device operation.
Can CPU voltage be changed?
- Unknown Location: The control for CPU voltage is not known. Contributions from knowledgeable users are welcome to help identify these locations.

Conclusion:
Modifying the GPU voltage on Qualcomm Xiaolong devices can be beneficial but is a risky process that requires careful attention to detail. Following these steps can help you safely make changes to reduce heat and extend battery life.
Disclaimer:
Voltage modification is inherently risky and can lead to device instability or damage. Users should proceed with caution and fully understand that they bear all responsibility for any consequences resulting from these modifications. Always back up your original files before making changes and verify compatibility with your specific device model.
