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 

Incompatible Flashing Tool: The version of the tool being used may not support the specific device or firmware structure.

Corrupt Firmware File: The .pac firmware file might be damaged or contains misformatted partitions (e.g., the NV partition).

Locked Bootloader: Attempting to flash custom or patched partitions (like a Magisk-patched boot.img) on a device with a locked bootloader.

Driver Issues: Faulty Spreadtrum/Unisoc USB drivers leading to corrupted data packets during transfer.  Step-by-Step Fixes  1. Change the Flashing Tool Version 

This is the most common fix. If one version fails, try another, as newer tools sometimes handle packet formatting differently. 

Download and try SPD Research Tool R25.20 or the newer R27.x versions.

Alternatively, if you are using a very new version, try a stable older version like R4.0.0001.  2. Verify or Repair the Firmware File 

If you have modified the firmware (e.g., patching for root), the tool may reject the packet format. 

Flashing Stock Only: Ensure you are using the original, unedited .pac file for your exact model.

HEX Editing (Advanced): For specific devices like the Nokia G21, users have reported that deleting a specific block (Offset 00100000 to 001FFFFF) in the partition file using a HEX editor can resolve this error.  3. Update or Reinstall USB Drivers 

Ensure your PC identifies the device correctly in "Spreadtrum COM Port" mode.  UpgradeDownload/ResearchDownload - 4PDA

The error message "the data packet with type-0x96-returned was misformatted" typically occurs in the context of communication between devices or systems, particularly in scenarios involving USB (Universal Serial Bus) communications. This error suggests that there was an issue with the way data was packaged or formatted when being sent or received, specifically related to a packet with the type identifier 0x96.

In the quiet hum of a well-tuned network, data packets are the invisible couriers of civilization. They move trillions of bytes per second, adhering to strict protocols defined by RFCs and industry standards. But every seasoned network engineer knows that silence is a luxury, and chaos is a heartbeat away.

One particularly cryptic message that has begun surfacing in system logs, proprietary device consoles, and Wireshark captures is:

"The data packet with type-0x96- returned was misformatted."

At first glance, this error appears to be a fragment of a forgotten dialect—part hexadecimal, part warning. But for those who have encountered it, this message is a red flag signaling deeper problems: protocol violations, firmware bugs, or even active intrusion attempts.

This article dissects the anatomy of the 0x96 packet type, explores why a "misformatted" flag triggers, and provides a systematic methodology for diagnosis and remediation.

// Expected packet format for type 0x96
typedef struct 
    uint8_t type;      // must be 0x96
    uint8_t len;       // must be 0x10
    float wind_speed;
    uint16_t direction;
    uint8_t reserved[10];
    uint8_t checksum;
 Packet96;
bool parse_packet(uint8_t *raw, size_t raw_len) 
if (raw_len < sizeof(Packet96)) 
log_error("Packet too short for type-0x96");
return false;
Packet96 p = (Packet96)raw;
if (p->type != 0x96) 
log_error("Not a type-0x96 packet");
return false;
if (p->len != sizeof(Packet96) - 2)  // subtract type and len fields
log_error("Length mismatch for type-0x96: expected %d, got %d",
sizeof(Packet96)-2, p->len);
return false;
uint8_t calc_csum = calculate_checksum(raw, raw_len - 1);
if (calc_csum != p->checksum) 
log_error("Checksum failed for type-0x96");
return false;
// Process packet...
return true;

Type-0x96 might require a sub-type or a TLV (Type-Length-Value) structure. If the payload is too short to include the first mandatory TLV, the packet is rejected.

Attackers sometimes inject malformed packets to trigger buffer over-reads or crash parsing routines. Type 0x96 is sufficiently obscure that it could be a fuzzing vector.

Indicators of compromise (IoC) to watch for:

"The data packet with type-0x96 returned was misformatted" is not just a nuisance – it’s a signpost pointing to a specific breakdown in communication. By understanding the packet structure, methodically capturing raw data, and applying targeted diagnostics, developers can quickly move from a cryptic log line to a robust fix. Whether the culprit is a loose wire, a buffer overflow, or a protocol version skew, the principles of disciplined parsing and hardware-aware debugging remain the same.

Next time you see type-0x96 in your error logs, don't curse the hex gods – thank them for the precise clue. Then reach for your hex dump and your logic analyzer, and restore order to the data stream.

Troubleshooting the "Data Packet with Type-0x96 Returned Was Misformatted" Error

In the world of networked hardware and data communication, precision is everything. When you encounter the error message "the data packet with type-0x96 returned was misformatted," it is a sign that the communication bridge between your software and a specific hardware component—usually a biometric scanner, a security dongle, or a proprietary controller—has broken down.

This error is notoriously specific yet frustratingly vague about the "why." Here is a deep dive into what this packet type represents and how to fix the communication breakdown. What is Packet Type-0x96?

In hexadecimal notation, 0x96 (decimal 150) often serves as a functional command or response code within specific SDKs (Software Development Kits). While not a universal TCP/IP standard, it is most commonly associated with:

Biometric Devices: Many fingerprint and iris scanners use 0x96 as a "Template Data" or "Status Acknowledgement" packet.

Legacy Industrial Controllers: PLCs (Programmable Logic Controllers) sometimes use this hex code for heartbeat signals or specific sensor readouts.

Encrypted Handshakes: Some specialized security hardware uses this packet type during the initial decryption phase.

When the system says the packet is "misformatted," it means the software received the data, but the structure (the header, the payload size, or the checksum) didn't match the expected blueprint. Common Causes of Misformatted Packets 1. Driver Mismatch

The most frequent culprit is a version mismatch between the hardware’s firmware and the computer’s driver. If the hardware sends a 64-bit data string but the driver is expecting a legacy 32-bit format, the packet will appear "misformatted." 2. Electrical Noise and Interference

In industrial or desktop environments, unshielded cables (USB or Serial) can suffer from EMI (Electromagnetic Interference). This can flip a single bit in the data stream. If the checksum at the end of the 0x96 packet doesn't match the corrupted data, the software rejects it as misformatted. 3. Buffer Overflows

If the device is sending data faster than the software can process it, the "tail" of one packet might be cut off or merged with the "head" of another. This creates a malformed string that the system cannot parse. 4. Power Supply Issues

Biometric scanners are sensitive to voltage drops. If the USB port isn't providing a steady 5V, the device may initialize the 0x96 packet correctly but fail to complete the transmission, leading to a truncated, misformatted result. Step-by-Step Solutions Step 1: Power Cycle and Port Swap

Start with the basics. Unplug the device and wait 30 seconds. If you are using a USB hub, remove it and plug the device directly into the motherboard (the back ports on a desktop). This ensures the device is getting full power and a clean data path. Step 2: Update (or Roll Back) Drivers

Check your device manager. If you recently updated Windows or your control software, the new driver might be interpreting the 0x96 packet differently.

Visit the manufacturer’s website for the specific "SDK Driver."

If the error started after an update, try the "Roll Back Driver" option in Device Manager. Step 3: Check for Firmware Updates

If the software is newer than the hardware, the hardware might need a firmware flash to "learn" the new packet structure. Manufacturers often release patches specifically to address packet formatting errors in newer OS environments. Step 4: Disable Power Management Windows often tries to save power by suspending USB ports. Go to Device Manager. Find Universal Serial Bus controllers.

Right-click each USB Root Hub > Properties > Power Management.

Uncheck "Allow the computer to turn off this device to save power."

The type-0x96 error is essentially a "lost in translation" message. By ensuring your drivers are synchronized with your firmware and eliminating physical interference, you can usually restore the handshake between your devices.

Are you seeing this error within a specific software (like a time-attendance system) or while developing your own code?

Since you have not specified the hardware or software platform you are using (e.g., a specific brand of PLC, drone flight controller, automotive diagnostic tool, or proprietary IoT gateway), I cannot give you a device-specific translation.

However, based on common industrial and embedded systems standards, Type 0x96 (Decimal 150) is most frequently associated with extended diagnostic responses, timestamped data logs, or proprietary handshakes in protocols like J1939, Modbus, or UAV (Drone) telemetry.
