Hi Dasaita support,
My unit has never been updated since I bought it in 2019. Details (from Settings > About):
- Model: PX6 (1024x600), 4GB RAM
- Android: 9
- Build: rk3399-userdebug 9 PQ2A.190305.002 20190828.185647 test-keys
- Kernel: 4.4.167 #593 Tue Aug 27 17:18:43 CST 2019
- MCU: MTCE_HA_V3.40_1 (Nov 11 2019 14:45:14)
- ZLink: APK 3.3.19, channel hengchangtong, mode wireless CarPlay + wired CarPlay + Android Auto
- Car: Toyota Vios 2004
My iPhone is on iOS 27 and wireless CarPlay disconnects sometimes.
Questions:
- Which firmware can I safely install on this unit? Is HA2_rk3399_9.0_ota(20211023) from the Firmwares page the right one? (The download file is named HA3_..._9.0_ota(20211023).7z, so I want to confirm.)
- Does that firmware include a newer ZLink that works better with iOS 26/27?
- Can this unit be upgraded to Android 10 (for example Vivid 20250401, which supports iOS 26)? If yes, please send the correct Update.zip / MCU files and the steps.
Thank you!
Update: I installed HA2_rk3399_9.0_ota(20211023) from the Firmwares page (renamed rk3399-ota-eng.hct.zip to update.zip, FAT32 USB, ticked "Wipe data and format flash", MCU not updated). It worked:
- Build is now: rk3399-userdebug 9 PI 20211022.210251
- ZLink went from 3.3.19 to 4.0.32 (channel HENGCHANGTONG-RK3399), still activated
- MCU is still MTCE_HA_V3.40_1
But I would still like to run the NEWEST firmware, not the 2021 one. My questions now:
1. Can this unit (PX6, 1024x600, MCU MTCE_HA_V3.40_1, Android 9) be upgraded to Android 10, e.g. Vivid10 (20250401) or MAX10 (20230803)?
2. If yes, please send the exact files (full image / recovery / update.zip / MCU for 1024x600) and the official steps.
3. Will my ZLink activation (HWLAC02BA4) and wireless CarPlay keep working after the upgrade?
Thank you!

Hello.
The Android 9 unit is EOL.
No new firmware or MCU will be released.
The firmware you have installed is already the latest available version.
Upgrading from Android 9 to newer Android systems is unsupported.
