Hello there, I have this unit that came with my 2020 Xtrail; Allwinner QUAD-CORE T3 k2001-nwd. It only came with Spotify and Waze installed, however, I got some APK apps, such as Google Maps, Play Store, Google Play Services. At first I installed Google Play and Google Services, and when I try to launch Google Play, at first it asks me to login to my account, after that, when I try to browse apps, it closes and crashes everytime, I tried everything but Google play keeps crashing or closing. Any idea of whats happening?

Aside from that, I'd like to know how to upgrade the Android OS, can you share a suitable version for my HU? maybe that solves the Google play issue, can I follow this guide?

[Android Head-Units] bjmsam:
That's encouraging! Does the firmware update address any of the issues in this thread? Would they be willing to tackle the rest?

Most urgent to me is the ability to change FM radio presets without looking at or interacting with the screen; the steering wheel controls and the hard buttons should select the next stored preset rather than seek the next frequency. Thanks!
[Android Head-Units] Sympl3x:
I'll chime in as well. I got the Bonroad 1GB/16GB model for a Rav4 last week. It's a great unit but definitely has its issues. Last night I spent several hours tinkering and trying to root with the Kingoroot and Kingroot apps. Couldn't get either one of them to work. Also, I seem to be having a weird issue with the internal storage. I cannot get some apps to work. I downloaded HERE and Sygic offline navigation apps from the playstore, however when I try to launch either one they crash with different messages about missing internal storage. I was able to get Waze installed and it runs along with some other apps like Weather Channel, but Waze doesn't support offline navigation fully from what I can tell.

I did a factory reset from settings but still get the internal storage errors with HERE, Sygic and possibly some other apps.

Here is the error I get when HERE maps tries to open. I will try to get the Sygic error posted later tonight.

"Make sure the memory card is in your system and start the app again"

How did others go about getting HERE installed? Also, has anyone successfully updated the Maps for the iGO navigation app built in?
[Android Head-Units] bjmsam:
iGO recognized the 2016.Q3 maps once I copied over the latest global_cfg.zip file, which is not included in the RAR package but available elsewhere. I have encountered no storage errors.

Does anyone know if there is a way to boot to recovery/bootloader/fastboot or anything? I'm pretty sure my internal storage is messed up. I have messaged the manufacturer and am awaiting a response. Some apps download just fine and others have the same issue. Does everyone have 2 internal storage partitions when they go into settings? I have one that is ~3Gb that looks to contain everything, then another that is ~7Gb that shows it has 0KB of data on it.

ah, just looked at the date next to os_update, didn't check inside.

it's gonna take a while until i post it...but personally i'm waiting for next one with the fixes for the feedback i gave them.\

they messed with notif bar auto-hide and overall text is smaller, which is worse than before.

i'll stick to what u have now, unless you want RDS text in radio app really bad :) they have some fixes coming for that though in next FW.

i don't know how to revert, the default update process accepts only newer updates, no rollbacks. probably do-able with time and skill, but i'd rather prefer waiting for new FW from the chinese support i'm in touch with.
[Android Head-Units] bjmsam:
I provided Bonroad with the feedback I posted in this thread but they have replied only "I will discuss what you provided with our engineer. We want to make our device much better." on 8 March and "When we have solution. I will let you know,ok?" on 18 March. Is the firmware specific to and maintained by each vendor independently, or are these updates produced by a common supplier?

The most important things that I need a firmware update to correct are 1) the ability to change radio presets using the steering wheel controls and hard buttons without looking at or interacting with the screen, and 2) Bluetooth reliably connecting to and syncing with both my phone for hands-free calls and my ELM327 adapter for the Torque OBD connection.
[Android Head-Units] bjmsam:
New update from Bonroad:

mcu.bin (128.0K, 2017-05-17 20:20)

os_update.zip (772.30M, 2017-05-17 20:22)

It took a few tries but eventually downloaded. There are no release notes. Instructions:

With both files on the USB stick, only the MCU updated. After moving mcu.bin to a subfolder, the OS updated. According to Settings -> About, the version of Android remains 6.0.1, the Linux 3.10.65 build date changed from 7 January 2017 to 30 March 2017, the MCU version changed from 1.13.5.00-20170103 to 1.15.8.00-20170329 and the OS Version changed from BSP 1.3 IVT 170107 to BSP 1.3.3.1 170330. So far it seems to address both of my main gripes. 1) While the Phone app still lacks a Favorites panel, the Bluetooth connection seems more reliable. 2) While the radio app interface remains unchanged, the steering wheel controls now select the radio preset rather than the frequency.
[Android Head-Units] oerli:
Yeah, it's the same one I posted.

it is dated 29th of februari, so not very recent. It is definitely not the "new firmware" we were waiting for....

Below are all updates from my seller I have. My unit is C1060801A3 but these updates can be installed on many other Allwinner T3 based models.

Dec:

OS - https: / / drive . google . com / open?id=0B7Uw1oCCyOAASG1tenk3VlRuSG8

Notes: If your device has OS older than Dec you need to install this one first. Create bootable sd-card from awc8060-1.2.2.3_161224.img file using PhoenixCard tool, insert it into HU sd slot and reboot. After installing you need to remove boot partition from the card to use it for next upgrades. Next versions are installed by simply inserting sd-card with os_update.zip, mcu.bin or android_config.zip file on it into sd-slot on booted device (rename files if needed). Unit will recognize updates on the card and the updating will start automatically.

I installed this one on my Silverstrong T3 and it worked great!

I am still looking at all the changes, but Radio is now very nice with RDS working and also BT seems more stable.

Still the lame Music app though.
[Android Head-Units] bjmsam:
It's great to see so much discussion on the RPDA site. The OS from 4/19 fails to install on my 1GB unit ("unknown error" at 76% just as someone else posted here), so I am running the MCU from 3/30 and the OS (and android_config) from 4/13 with similar observations (BT and radio better, music still too hard to navigate). I am most pleased that the SWC track buttons now change the radio preset rather than seeking and hope the same change is made for the hard buttons to the right of the screen as well (convenient for the passenger when the radio app is not displayed). I also hope that the minimum radio volume issue can be addressed via firmware (level 1-7 are identical and too loud when parked with the engine off). Regardless, it's very good and getting better as expected!
