I read somewhere that if I erase the eMMC, the box will be forced to switch to Maskrom. I erased the eMMC using the multitool, and then restarted the box with reset button pressed then released, and connected through USB to laptop and it was detected by AndroidTool as Maskrom, and was able to flash the original Android image using FactoryTool

Thank you for your response. So, seems that if I cannot perform a HW modification, then I am stuck with Armbian on this box, and no way to go back. Few points that come to my mind: This support that I need in uboot cannot be enabled for example by building the armbian image with some specified flags? If I made a backup using multitool from the original Android image, is there a way to extract from it the uboot, and override the existing one? I have a new identical box from which I was able to dump its existing Android image using a tool called rkdumper. I think it dumped a uboot.img (will need to double check). Can I overwrite somehow the current armbian uboot with this img using multiboot?

I have an H96Max RK3318 box which I flashed with Armbian. Is there a way to switch back to Android (original firmware). With the original firmware, pressing the reset button at power connection would take the box into recovery mode. This is not the case for Armbian, so not sure how I can flash back Android on this box?

I had a V11 and was able to get Bluetooth to work by performing the following steps: 1) run sudo rk3318-config and accept all defaults. 2) Create the following symbolic link: sudo ln -s /lib/firmware/brcm/BCM43342.hcd /lib/firmware/brcm/BCM.hcd 3) Reboot sudo reboot

Thank you very much. Yes it did. After creating the symbolic link, Bluetooth is now working successfully and I am able to pair and connect to my Airpods.

This is an old thread. I made some progress by running the rk3318-config and accepting the default. Using bluetoothctl I see it works, and I can scan on. However, either it scans very few devices or none. Following is the dmesg outcome. It complains about a missing patch for BCM43342A. How can I add this patch? dmesg | grep -i blue [ 10.361265] Bluetooth: Core ver 2.22 [ 10.361501] NET: Registered PF_BLUETOOTH protocol family [ 10.361514] Bluetooth: HCI device and connection manager initialized [ 10.361545] Bluetooth: HCI socket layer initialized [ 10.361559] Bluetooth: L2CAP socket layer initialized [ 10.361607] Bluetooth: SCO socket layer initialized [ 10.432142] Bluetooth: HCI UART driver ver 2.3 [ 10.432184] Bluetooth: HCI UART protocol H4 registered [ 10.432193] Bluetooth: HCI UART protocol BCSP registered [ 10.432374] Bluetooth: HCI UART protocol LL registered [ 10.432397] Bluetooth: HCI UART protocol ATH3K registered [ 10.432489] Bluetooth: HCI UART protocol Three-wire (H5) registered [ 10.432863] Bluetooth: HCI UART protocol Intel registered [ 10.435956] Bluetooth: HCI UART protocol Broadcom registered [ 10.436076] Bluetooth: HCI UART protocol QCA registered [ 10.436085] Bluetooth: HCI UART protocol AG6XX registered [ 10.441003] Bluetooth: HCI UART protocol Marvell registered [ 10.820901] Bluetooth: hci0: BCM: chip id 83 [ 10.821724] Bluetooth: hci0: BCM: features 0x0f [ 10.823414] Bluetooth: hci0: BCM43342A [ 10.823458] Bluetooth: hci0: BCM (001.002.003) build 0000 [ 10.823836] Bluetooth: hci0: BCM: firmware Patch file not found, tried: [ 10.823862] Bluetooth: hci0: BCM: 'brcm/BCM.rockchip,rk3318-box.hcd' [ 10.823869] Bluetooth: hci0: BCM: 'brcm/BCM.hcd' [ 18.309192] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 18.309238] Bluetooth: BNEP filters: protocol multicast [ 18.309273] Bluetooth: BNEP socket layer initialized [ 18.357504] Bluetooth: MGMT ver 1.22 [ 56.740638] Bluetooth: RFCOMM TTY layer initialized [ 56.740700] Bluetooth: RFCOMM socket layer initialized [ 56.740747] Bluetooth: RFCOMM ver 1.11 The outcome link from armbianmonitor -u is: https://paste.armbian.com/qusikoqege

I am new to this. I have an H96Max Android TV box which I flashed successfully with Armbian 23.02.2 Bullseye with Linux 5.15.93-rockchip64the latest armbian image. Wifi is running fine. However, I failed to activate bluetooth. I read several post around the same topic with no luck. I am attaching several logs I collected and hope it can clarify more the case, so someone can help resolving this. =============================================== root@rk3318-box:/# dmesg | egrep -i 'blue|firm' [ 0.000000] psci: PSCIv1.1 detected in firmware.
