"Failed: the data packet with type(0x96) returned was misformatted"

The error message is a specific failure code encountered when using Unisoc/Spreadtrum flashing tools like ResearchDownload , UpgradeDownload , or FactoryDownload . It indicates that the flashing tool has received an unexpected or corrupted data response from the device, preventing it from proceeding with the firmware installation. Meaning and Causes

Volume Down

Ensure the device is completely powered off before connecting, or try holding the (or Up) button while plugging it in to force the correct boot mode. "Failed: the data packet with type(0x96) returned was

Inspect the Firmware (.pac) File

: The error can also mean the data packet within the firmware file itself is corrupted. Try re-downloading the firmware or checking its integrity. If packet includes checksum/MAC, recompute and compare to

To resolve the issue, follow these steps: Maintain protocol version logging : In any custom

  1. Maintain protocol version logging: In any custom client-server application, log the remote’s announced version on handshake.
  2. Use robust serialization: Avoid raw structs over the network. Use Protocol Buffers, MessagePack, or CBOR which have built-in version tolerance.
  3. Health checks for package mirrors: If you run a repository, run a daily test script that requests a type 0x96 packet from each mirror and validates its formatting.
  4. MTU discovery: Always enable Path MTU Discovery (PMTUD) in your network stack and handle ICMP fragmentation needed messages.

Ensure you are using the latest version of the flashing utility (e.g., versions like R27.23.1902 or newer) that supports modern Unisoc processors. Verify Firmware Integrity: Re-download the firmware package to ensure the file is not corrupted. Check Hardware Connections:

Delete everything in this folder (skip files that say they are "in use"). Restart the installer. 2. Disable Real-Time Web Protection
