Understanding Why Your Phone Isn’t Turning On After SP Flash Tool Flashing

The primary reason for encountering problems or a non-responsive phone post-flashing lies in potential interruptions during the process. A stable connection and continuous device connectivity to the PC are critical elements. This guide addresses the necessary steps to rectify a phone that remains unresponsive after using SP Flash Tool.

Methods for Resolving Phone Not Turning On After Flashing

1. Charge Your Phone Before Flashing:

  • Ensure your smartphone boasts a fully charged battery before initiating the flashing process.
  • Aim for at least a 50% battery charge to facilitate the initial boot after flashing.
  • If the battery level is unknown, it’s advisable to charge for approximately an hour as a precaution.

2. Keep Your Phone Connected:

  • In cases where the phone stays unresponsive after flashing, maintain its connection to the computer.
  • Allow sufficient time, as it might take a few hours for the device to rejuvenate automatically.

3. Download the Correct Firmware:

  • Source firmware from reputable and official channels to circumvent compatibility issues.
  • Prioritize checking the MD5 checksum of the downloaded file before proceeding with the flashing.

4. Extract Firmware Accurately:

  • Some devices utilize OPF file format, necessitating precise extraction with compatible tools like MABT.
  • Verify the contents of the extracted files, particularly country-specific ones, for accurate flashing.

After extracting the OPF file, carefully inspect the contents of the extracted file. MABT might separate country-specific firmware files, which you should manually select in the SP Flash Tool, aligning them with the scatter file.

5. Verify Compatible Firmware:

  • Confirm compatibility by cross-referencing firmware versions and utilizing the IMEI number.
  • Flashing non-compatible firmware may result in irreversible damage.

6. Exclude Cache & UserData Images:

  • Eliminate unnecessary files such as cache, dalvik cache, and user data images during the flashing process.

7. Exclude Verified Boot Images:

  • Skip files related to server and CDT engineering during the flashing process.

8. Flash With Unlocked Bootloader:

  • Unlock the bootloader before initiating the flashing of custom ROMs or scripts.

9. Flash With Correct Scatter File:

  • Ensure the scatter file is accurate and devoid of corruption, as it guides the flashing process.

10. Flash With Correct IMG Files:

  • Validate that all firmware image files are correctly loaded into the SP Flash Tool.

11. Edit Scatter File Before Flashing:

  • If anomalies are detected, manually edit the scatter file using tools like Notepad++ (download link) .

12. Format All & Download:

  • Utilize the “Format All & Download” mode in SP Flash Tool to clear internal memory and flash firmware files.

Caution: Exercise care when utilizing the ‘Format All & Download’ option, as it has the potential to erase all contents within the EMMC memory, including vital data such as bootloader, recovery files, IMEI codes, and other hardware-related information. Only resort to this option when there are no alternative solutions available.

13. Short Flashing Pins:

  • For advanced users with the necessary tools, short flashing pins (Test points) on the device’s motherboard may be considered.

NOTE:- Ensure you have a multimeter and soldering tools for this method. If you lack experience with these tools, it’s advisable to seek assistance from a professional.

14. Check Hardware:

  • If all else fails, hardware-related issues may be the culprit. Seek professional assistance to address potential IC problems.


While the process of flashing custom ROMs involves inherent risks, a non-responsive device post-flashing doesn’t necessarily equate to irreparable damage. This guide provides diverse methods to revive your device. Should challenges persist, professional intervention may be warranted.
