The Data Packet With Type0x96 Returned Was Misformatted Install !!hot!! May 2026

This error—"the data packet with type (0x96) returned was misformatted"—is a common roadblock when using SPD (Spreadtrum) flashing tools like ResearchDownload or UpgradeDownload. It essentially means the tool failed to read or communicate correctly with the firmware packet it's trying to push to your device.

Here is a blog post designed to help you troubleshoot and solve this issue.

How to Fix "Data Packet with Type (0x96) was Misformatted" During Flashing

If you're trying to flash a PAC file onto your device and keep hitting the 0x96 misformatted data packet error, you aren't alone. This error often indicates a breakdown in communication between the flashing tool and the device's hardware, often related to the specific tool version or the state of the NV (Non-Volatile) data on the phone. Why is this happening?

The "0x96" error code typically pops up when the tool is unable to proceed with the specified firmware. This could be due to:

Incompatible Tool Version: You might be using an older version of the Research or Upgrade Download tool that doesn't support your specific PAC file.

Damaged NV Data: The Non-Volatile data on the phone might be crashed or unreadable.

Driver or Connection Issues: Faulty USB ports or improperly installed drivers can lead to corrupted data packets during the transfer. Step-by-Step Solutions 1. Switch to the Factory Download Tool

Many users find success by switching from the standard ResearchDownload tool to the SPD Factory Download Tool. This version is often more robust for devices that are throwing "misformatted" errors. 2. Update Your Tool Version

Ensure you are using the latest available version of the ResearchDownload or UpgradeDownload tool. Older versions may lack support for newer "bin packet" structures found in modern firmware. 3. Refresh Your Connection and Drivers Poor connectivity is a silent killer for flashing tasks.

Reinstall Drivers: Ensure your Spreadtrum/SPD drivers are correctly installed.

Check the Hardware: Try a different USB cord or a different port on your PC.

The Battery Trick: Power off the phone completely. Remove the battery (if possible) and reinsert it before connecting it to the PC. 4. Try the Volume Down Shortcut

Sometimes the "waiting" or "misformatted" error is triggered because the phone isn't in the correct boot mode. Try holding the Volume Down button while connecting the USB cable to force it into the correct state for flashing. Final Thoughts This error— "the data packet with type (0x96)

Flashing firmware is always a bit of a gamble, but the 0x96 error is usually a software-level mismatch. By trying the Factory Download Tool or updating your software version, you can usually bypass this hurdle and get your device back up and running.

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

Protocol Mismatch: The flashing tool is unable to interpret the packet type (0x96) sent by the device's bootloader, often because of a version conflict between the tool and the firmware.

Firmware Incompatibility: The tool is attempting to flash a firmware file that does not match the specific hardware or partition layout of the device.

Data Corruption: The data being transferred is corrupted during the process, which can be caused by faulty USB cables, unstable ports, or an improperly formatted .pac firmware file. Recommended Solutions

Switch Flashing Tools: If you are using ResearchDownload or UpgradeDownload, try switching to the Factory Download tool, which is often more robust for stubborn errors.

Update Tool Version: Ensure you are using a version of the tool compatible with your processor (e.g., Unisoc T616 requires newer versions like R27.23.1902). Hardware Connection Check: Use a different high-quality USB cable.

Connect the device to a rear USB port (if using a desktop) for a more stable power supply.

Ensure the device is completely powered off before connecting, or try holding the Volume Down (or Up) button while plugging it in to force the correct boot mode.

Verify Firmware Source: Re-download the firmware (PAC file) to ensure it isn't corrupted. Some users suggest that manually editing blocks in a HEX editor can fix misformatting, but this is advanced and carries high risk.

Enable "Reparition": In the tool settings (the "gears" icon), ensure the repartition option is checked if you are moving between different firmware versions, as this can resolve "Incompatible partition" issues that lead to packet errors.

Troubleshooting the "Data Packet Type 0x96" Installation Error

The error message "the data packet with type 0x96 returned was misformatted" is a low-level communication failure that typically occurs during software installations or updates. It indicates that the installer received a data packet from a server or local storage that it does not recognize or cannot decode.

This specific error code often points to a corruption in the installation files, a interrupted download, or a mismatch between the installer version and the data being processed. Common Causes

Corrupted Download: The most frequent cause is a "bit flip" or data loss during the download process, leaving the .msi or .exe file incomplete.

Network Interference: Antivirus software, firewalls, or VPNs can sometimes strip or alter data packets during transit, causing the "misformatted" status.

Incompatible Installer: Trying to run an old installer against a newer server-side database (or vice versa) can trigger packet type mismatches.

Storage Issues: Bad sectors on a hard drive or a failing USB drive can corrupt the data as it is being read for installation. Step-by-Step Solutions 1. Clear the Installation Cache and Re-download

The simplest fix is often to start over with a fresh set of data. Delete the current installation file.

Clear your browser's temporary internet files or use a different browser.

Download the installer again, ideally from the official developer website. 2. Disable Security Software Temporarily

Aggressive SSL inspection or packet filtering by third-party antivirus programs (like Avast, Norton, or McAfee) can mangle data packets. Temporarily disable your Antivirus/Firewall. Retry the installation. prevent recurrence by:

Note: Remember to re-enable your security software immediately after the test. 3. Run as Administrator

Permissions issues can sometimes lead to "misformatted" errors if the installer is blocked from correctly writing or reading temporary data. Right-click the installer file. Select "Run as Administrator." 4. Verify System File Integrity

If the error persists across different software installations, your Windows Installer service or system files might be compromised. Open the Command Prompt as Administrator. Type sfc /scannow and press Enter. Wait for the process to complete and restart your computer. 5. Check Disk for Errors If the data is being misread from your drive:

Right-click your primary drive (usually C:) in File Explorer. Go to Properties > Tools > Error Checking and click Check. Technical Deep Dive: What is 0x96?

In hexadecimal notation, 0x96 represents the decimal value 150. In many network protocols and installer frameworks, packet types are assigned specific IDs. When the software expects a "Type A" packet but receives a "Type 0x96" (which it might not be programmed to handle), it flags it as misformatted because it lacks the correct structure to proceed.

Here’s a draft for a technical post regarding the error:
“The data packet with type 0x96 returned was misformatted install.”

Title: Troubleshooting “Data packet type 0x96 misformatted” Installation Error

Body:

If you’ve encountered the error message:

“The data packet with type 0x96 returned was misformatted install”

during an installation or firmware update process, you’re likely dealing with a low-level communication issue between a host system (e.g., a PC, embedded flasher, or update utility) and a target device (microcontroller, network card, IoT module, etc.).

3.5 Firewall or Proxy Alteration

Some transparent proxies or deep packet inspection (DPI) firewalls modify packets (e.g., injecting headers, stripping options). If a firewall misidentifies traffic as HTTP and attempts to normalize it, a binary protocol packet (type 0x96) can be truncated or padded.

Quick fixes to try

  • Force both sides to a single protocol/version.
  • Increase logging on both sender and receiver.
  • Replace or simplify the 0x96 payload to a minimal valid form.
  • Retry over a different network or directly between endpoints.
  • Roll back recent changes that modified packet serialization.

Troubleshooting steps:

  • Verify the firmware file – Redownload or rebuild it, check its integrity (hash, size).
  • Check communication parameters – Confirm baud rate, parity, stop bits, and flow control.
  • Use a logic analyzer or serial monitor – Capture the raw exchange to see if the 0x96 packet is malformed or missing bytes.
  • Update or roll back the flashing tool – The installer itself may have a bug.
  • Reset the device – Power cycle, assert hardware reset, or force bootloader mode again.
  • Try a different cable/port – Hardware faults can corrupt packets at random.

a. Verify Packet Dump

Capture raw communication (e.g., Wireshark, tcpdump). Filter for type 0x96 and compare against protocol specification.

2.2 Firmware Flashing Tools (dfu-util, esptool, nrfutil)

Embedded developers frequently see this error when flashing microcontrollers. For example:

  • DFU (Device Firmware Upgrade) over USB: The device sends back a DNLOAD or UPLOAD status packet. Type 0x96 might be a vendor-specific “busy” or “retry” signal. If the host tool expects a wLength of 2 bytes but receives 0 or 4, the packet is flagged as misformatted.
  • ESP8266/ESP32 flashing: Esptool.py uses a custom SLIP protocol. A malformed response packet with type 0x96 often indicates a baud rate mismatch or a damaged bootloader.

Preventing Future Occurrences

Once you have successfully installed the software, prevent recurrence by:

  1. Freezing the driver version – Do not allow Windows Update to automatically update device drivers.
  2. Creating a driver backup using pnputil /export-driver * .\backup.
  3. Using a dedicated installation user account with no AV or security policies.
  4. If developing firmware, always include a version field in your 0x96 response packet and pad to a fixed size (e.g., 64 bytes).
