Troubleshooting 'Prepare IDB Fail' Error on MXQ-4K Devices
If you're experiencing issues with flashing your MXQ-4K device, you may encounter an error message stating 'Prepare IDB Fail'. This issue can be frustrating, but it's not necessarily a sign that your device is bricked. In this article, we'll guide you through the troubleshooting process to resolve this error and get your device up and running again.
Identifying the Issue
The first step in resolving the 'Prepare IDB Fail' error is to identify the symptoms. If your screen is showing only the MXQ-4K logo, it's likely that you've successfully short-circuited the nand flash. This can be a good sign, as it indicates that your device is still functional.
Using Rockusb to Flash the Device
To resolve the issue, you'll need to use Rockusb to flash an update.img file onto your device. To do this, follow these steps:
1. Connect pin 8 and 9 on the nand with a needle and plug in the OTG USB cable into your PC.
2. Use the Rockusb tool to upload the update.img file to your device.
RKBatchTool Troubleshooting
If you're using RKBatchTool, you may encounter issues when trying to write an update.img file to the nand. If this happens, you'll see a 'Prepare IDB Fail' error message. To resolve this issue, follow these steps:
1. Click the restore button and upload the update.img file.
2. Ensure that the square in RKBatchTool turns blue (if it doesn't, try retrying).
Precautions
Before attempting to flash your device, make sure that there is no SD card connected. This can cause the bootloader to become corrupted, making it difficult or impossible to recover.
The 'Prepare IDB Fail' error on MXQ-4K devices is often a sign of a minor issue that can be easily resolved with the right troubleshooting steps. By following the guidelines outlined in this article, you should be able to resolve this error and get your device up and running again. Remember to always start counting pins from the edge of the chip where the small circle is molded or printed on, and use a magnifying glass or camera zoom to ensure accuracy.
