🔔 Important Notice: OTA Update & Firmware Upgrade Instructions

Dear Carpuride Users,

We would like to provide an important update regarding the recent OTA update issue reported by some users, as well as changes to the firmware upgrade process for selected Carpuride models.

We apologize for any inconvenience this may have caused and appreciate the feedback from our community. 🙏


⚠️ 1. Recent OTA Update Issue

Recently, a server-side data synchronization issue affected the OTA update process for some devices. In certain cases, this could cause the firmware package verification to fail during an OTA update, resulting in the device failing to start normally or repeatedly restarting.

✅ Our technical team identified the issue and has completed the necessary server-side fixes. The cloud service is now operating normally.

🟢 If your device is currently working normally, please do not perform an unnecessary firmware update solely because of this notice.

🔴 If your device experienced a startup or reboot issue after a recent OTA update, please contact Carpuride Support for the appropriate recovery firmware and instructions.


🔄 2. Important Change to the Firmware Update System

As part of our latest decoder software update, Carpuride has migrated the decoder software to a new server infrastructure to improve communication stability, decoding performance, and future update reliability.

Because the new server uses an updated communication architecture, devices running decoder software versions older than the versions listed below cannot upgrade to the latest version through the previous OTA update channel.

6-inch

LT-M602PRO-S9-V4.19

7-inch

LT-M702PRO-S9-V3.28

If your current decoder software version is below the applicable version above and you need to update to the latest decoder software, a manual TF card update is required. 💾


📋 3. Models Covered

This update information applies to the following models:

For affected devices requiring an update, Carpuride currently recommends using the TF card local update method, which provides a more controlled and reliable upgrade process. 🛡️


❓ 4. Do I Need to Update My Device?

🟢 If your device is working normally and you do not need the latest decoder software:
No immediate action is required.

🔵 If you want to update to the latest decoder software and your current version is below the version listed above:
Please contact Carpuride Support. A manual TF card update will be required.

🔴 If your device cannot start normally or repeatedly restarts after an OTA update:
Please stop attempting additional OTA updates and contact Carpuride Support for recovery assistance.


🚫 5. Please Do Not Install Unverified Firmware

Carpuride products may have hardware or firmware differences between production batches.

⛔ For this reason, please do not download or install firmware obtained from unofficial websites, forums, shared links, or other users.

Installing firmware intended for a different hardware revision may cause startup problems, missing functions, compatibility issues, or other unexpected behavior.
