Jetour Traveller 2026 Infotainment OTA Firmware G7PH_018T_T1J_OS3.0_SOP_FULL_24883_260327_R.zip

Applicable Models: Jetour Traveller T1J, 8AT, Desay Infotainment Unit, Version 08

I. Core Fixes

Corrected terrain mode menu bug. The T1J-8AT (2WD version) factory chassis hardware does not support Sand Mode. The old V08 firmware incorrectly displays the [Sand Mode] option on the infotainment UI. Tapping this option causes abnormal CAN messages, distorted instrument cluster display, and terrain mode lock-up on some vehicles.

After flashing this package:

Sand Mode is removed from the menu; only driving modes supported by the vehicle hardware remain (Standard / Eco / Sport / Snow).
Fixed CAN communication matching issue between infotainment and body domain controller; eliminates intermittent instrument display anomalies and terrain-related UDS DTCs during mode switching.

II. Additional Synchronized Fixes (included in this batch of after-sales packages)

Synchronized driving mode UI: The main screen and instrument cluster refresh simultaneously when switching driving modes, resolving desynchronized display.
Fixed unresponsive terrain menu taps and occasional crashes on some vehicles.
Optimized CAN signal verification for Desay host, reducing information desynchronization between infotainment and chassis modules.
Minor optimization for 360° panoramic view switching logic, mitigating stuttering when panoramic view is triggered by steering (existing issue in V08).
Retains all original OS3.0 features. This is a full patch package for V08 and will NOT upgrade the system to a higher version.

III. Important Limitations (Key for service operation)

Only for T1J 8AT 2WD vehicles with Desay host.

DO NOT flash on Shanhai T2, 4WD T1J or T1L Freer. Hardware differs; wrong firmware flash will lock the host and trigger the Unauthorized User Access error.
Host must be Desay (NOT Huayang host).

This is a dedicated fix package for V08. It will NOT upgrade to V09/V10. The system version number remains V08 after flashing; only the menu bug is patched.
Offline full flashing via USB drive. Package size: 5.94GB. Upgrade duration ~40 minutes. Keep ignition at ON position during the whole process. Power loss or engine shutdown mid-flash is strictly prohibited.
Personalized settings (Bluetooth, Wi-Fi, sound effects) will be reset after flashing and require reconfiguration.
ADB will not be unlocked. Engineering mode password remains unchanged; system security verification stays intact.
