The Data Packet With Type-0x96- Returned Was Misformatted ((free)) May 2026

The error message "The data packet with type (0x96) returned was misformatted" is a specific error (code 275) that occurs when using SPD Upgrade Tool or ResearchDownload to flash firmware onto Spreadtrum (Unisoc) based devices. It indicates a communication mismatch or data corruption during the flashing process, often occurring at the FDL2 stage. Potential Causes

  • 0x prefix: Standard notation for hexadecimal (base-16).
  • 96 hex: This translates to 150 in decimal (since 9*16 + 6 = 150).

Possible causes

  1. Sender implementation bug (wrong serialization for type 0x96).
  2. Version mismatch: sender and receiver use different protocol versions or schema.
  3. Encoding/endianness mismatch.
  4. Fragmentation/assembly bug causing packet truncation or duplication.
  5. Network corruption (bit flips) or intermediary device modifying bytes.
  6. Incorrect content-length or length-prefix in the packet.
  7. Wrong packet type value due to misrouted or misidentified message.

If you meant something else (e.g., a specific protocol like PROPER or 0x96 as a proprietary command code), please clarify and I can tailor the post accordingly. the data packet with type-0x96- returned was misformatted

Suggested Fix

  • Validate packet length before parsing
  • Log and discard malformed packets
  • Add framing / escaping if delimiters are ambiguous

4. Forensic Analysis Steps

To resolve this issue, perform the following analysis on the raw hex dump of the packet. 0x prefix : Standard notation for hexadecimal (base-16)
