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
0xprefix: Standard notation for hexadecimal (base-16).96hex: This translates to 150 in decimal (since 9*16 + 6 = 150).
Possible causes
- Sender implementation bug (wrong serialization for type 0x96).
- Version mismatch: sender and receiver use different protocol versions or schema.
- Encoding/endianness mismatch.
- Fragmentation/assembly bug causing packet truncation or duplication.
- Network corruption (bit flips) or intermediary device modifying bytes.
- Incorrect content-length or length-prefix in the packet.
- 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)
