Ts10.2.2 Firmware Official

# On running device
cat /proc/cpuinfo
dmesg | grep -i "machine model"

No firmware is perfect. Users have reported several issues with Ts10.2.2. Here are solutions for the most frequent ones.

Most likely recovery-based OTA:

  • Rollback protection via misc partition storing version counter.

    • Example updater-script snippet:

    ui_print("Applying TS10.2.2 update");
package_extract_file("boot.img", "/dev/block/by-name/boot");
package_extract_file("system.sqsh", "/dev/block/by-name/system");
write_raw_image(package_extract_file("dtb.img"), "dtb");
set_progress(1.0);

    Wireless Android Auto and wired CarPlay were notorious for random disconnections on older builds. Ts10.2.2 includes a revised USB driver stack and Bluetooth stack (version 5.0 negotiation) that reduces dropouts by an estimated 70%.

    If you have both versions:

    diff -Naur ts10.2.1_rootfs/ ts10.2.2_rootfs/ > fw_diff.patch

    Typical changes:

    Binary diffing (using bsdiff or radiff2): Ts10.2.2 Firmware

    radiff2 ts10.2.1/boot.img ts10.2.2/boot.img

  • Enter recovery mode:

  • Navigate the recovery menu (using volume buttons to move, power button to select): # On running device cat /proc/cpuinfo dmesg |

  • Wait for the process to complete. Do not interrupt power. The unit may reboot 2–3 times. A success screen will appear.

    • Cause: Incompatible MCU (Microcontroller Unit) version. Fix: No firmware is perfect
