which nand pins to short to unbrick a tv box

TV boxes have become popular devices for streaming media and accessing online content. However, sometimes these devices may encounter issues or become “bricked,” rendering them unusable. In such cases, shorting certain NAND pins can help unbrick the TV box. This article will provide a detailed explanation of which NAND pins to short for unbricking a TV box.

What are NAND pins?

NAND pins are the input/output pins on the NAND flash memory chip used in TV boxes. These pins are responsible for reading and writing data to the memory chip. By shorting specific NAND pins, we can reset the device and potentially unbrick it.

Identifying the NAND pins

Before attempting to short any pins, it is crucial to identify the correct NAND pins on the TV box’s circuit board. The location of these pins may vary depending on the device model and manufacturer. It is recommended to consult the TV box’s technical documentation or seek guidance from online forums or support communities to locate the NAND pins accurately.

Precautions

Shorting NAND pins can be risky if not done properly. It is essential to take necessary precautions to avoid damaging the TV box or causing further issues. Some precautions to consider include:

1. Ensure the TV box is powered off and unplugged before attempting any pin shorting.
2. Use a non-conductive tool, such as a plastic or wooden stick, to avoid electric shock.
3. Work in a well-lit and static-free environment to minimize the risk of accidental damage.

Shorting NAND pins

Once the correct NAND pins are identified and necessary precautions are taken, follow these steps to short the pins:

1. Locate the specific pins that need to be shorted. These pins are usually labeled on the circuit board.
2. Using the non-conductive tool, gently touch the two pins simultaneously for a few seconds.
3. Remove the tool and reassemble the TV box.

Commonly shorted NAND pins

While the specific NAND pins to short may vary depending on the TV box model, some commonly shorted pins include:

• CE (Chip Enable) Pin: Shorting this pin can reset the NAND flash memory.
• RE (Read Enable) Pin: Shorting this pin can force the TV box to boot into recovery mode.
• WE (Write Enable) Pin: Shorting this pin can erase the existing firmware and allow flashing a new one.

Seeking professional assistance

If you are unsure about shorting the NAND pins or if the TV box remains unresponsive after attempting the procedure, it is advisable to seek professional assistance. Professional technicians have the expertise and tools required to unbrick the device safely and effectively.

Conclusion

Shorting the correct NAND pins can be an effective method to unbrick a TV box. However, it is crucial to exercise caution and follow the necessary precautions to avoid further damage. Identifying the correct pins and seeking professional assistance when needed are essential for a successful unbricking process. By following these guidelines, you can potentially revive your TV box and resume enjoying your favorite media content.
