Installation Troubleshooting |

|---|---|
| Issue | Solution |
| 1) VCRUNTIME140.dll or MSVCP140.dll is missing, so the program will not run. | Watch the video guide |

| 3) I cannot power on the tablet. | Press and hold Power + Volume Up + Volume Down together for 6 seconds, then press the Power button to turn the tablet on. |
| 4) There is no compressed file inside the RomFiles folder. | ① Delete the RomFiles folder → then download the firmware again through Software Fix. ② If you see the message "Resource is unzippping...", close the Software Fix program by clicking the X button in the top-right corner. ③ Check whether the compressed file is present. (If it is still missing, repeat the same process.) |
| 5) BROM protocol error. Check device environment. | ① The cable may be faulty. ② If you are using a desktop PC, connect it to a rear USB port. (This does not apply to laptops.) ③ If the issue continues, try again with one of the recommended cables listed above. |
| 6) Error occurred, please contact tool owner | ① While the cable is connected, press and hold Power + Volume Up + Volume Down together for 6 seconds → then turn on the tablet. ② On your PC or laptop, click Read PT → then tap Restart on the tablet.
