According to the query of ZNDS Smart TV Network, Hayes line brush failed, and the possible reasons are as follows:

1. The burned fast boot image does not match the current single board model or Flash;

2. There is a problem with DDR on the single board, so DDR initialization cannot be performed normally;

3. If it is a security chip, you need to confirm whether you need to use a programmer for writing (Conax and Verimatrix are required for high-level types)

4. If it is a security chip, it is necessary to confirm whether the current image has been signed and whether the signature is correct. Please note that the key used for signing must be the same as the key used for chip startup verification.
