I recently bought a generic android head unit from Ali Express. It actually works well but I really need to connect it to a CAN bus and write some additional software (background: I want to replace the factory unit in a Nissan Leaf, so it needs to display some vehicle info, show the heater settings and set up the charge timer). I have experience in Android app development and embedded Linux, but I'm still a 'noob' when it comes to Android hacking (root access etc).
I'm pretty sure I will need root access to do what I want. It has 'CAN tx / rx' pins on the back, and I am pretty sure they are wired to one of the serial interfaces internally (I will need an adapter to convert UART to CAN as well). I played around with an app to access the serial ports (i.e. ttyxxx) but I didn't have permission to use many of them - probably the ones I wanted!
I don't want to re-write the existing music player, amp control and radio; I just want to add a new app to carry out my vehicle-specific functions.
I tried the root process given here but it didn't work.
Here are the device details:
Model: S07
MCU Version: MTCB-HA-V2.60
Android Version: 4.4.4_01062015
Kernel Version: 3.0.36+ [email protected] #278
CPU: ARM7 1.6G x 2
CPU/SOC is an RK3066 on a modular board. Pictures attached.
It doesn't have any physical buttons except reset - there are touch sensitive buttons for power, back and volume. It has one SD card slot for map data and no USB on the front (several on the back).
I haven't figured out how to get to the recovery console, or connect it to a PC via USB.
Any suggestions for how to root? Or get to recovery console?
Anyone else with a similar device?
Check out the Huefi thread above. It has everything you need. first page covers root. basically, download the rom you want, put it on the GPS SD card, insert it, and wait for it to ask you to update. Once you do that, it will be rooted. there is no other way to root it if it has 4.4.4. DO NOT INSTALL A MCU file for it unless it is for HA devices. HA is the manufacture of the unit, and if you use an MCU file for a different device, you run the risk of loosing the physical buttons on the unit. This can be repaired by going into recovery and flashing the HA MCU, but that is a lot of extra work
Hi! Thanks for your reply.
I was wary about installing a new image because I don't want to lose the existing radio app and amplifier controls (which are specific to the device rather than the RK3066 SOC module, if I have understood the structure correctly).
* Would a new image replace these apps, or are they actually in the MCU firmware anyway?
* Can I back up my current image first? I looked at some backup tools, but they all needed root access... =Catch 22.
Sorry for noob questions... I'm getting the hang of Linux but still new to messing with Android at a low level. I'd love to play around with a stripped Ubuntu or similar on the device, but I don't want to have to write my own software for the radio parts - at least not yet.
BTW do you know how the bootloader system works? Is it possible to boot from SD card or USB (therefore allowing some other OS to be booted without replacing the onboard image)?

I cant help with the bootloader issues, but I can with some of the others:
-Radio and Amplifier apps are the same on all units, or should I say is compatible across all units. If you were to go into the settings, then factory settings and enter 126 as the password, you can see all the settings you need to make sure your unit functions after upgrading your rom image.
-You can not back up your factory image. its not possible. You can always reach out to your seller and ask them if they will send you a copy of the factory firmware.

SUCCESS! I just downloaded and installed the latest image from Malaysk (I think?) and it looks like it is working well! Radio, music player and amplifier work, and I have root access. Woo! So far so good... Thanks!

Hi, I also didn't know the screen resolution, and it is not mentioned on the "About" screen.
In the settings menus, I found some options for recording a video of the display (I don't know why!) and the maximum resolution there was 1024 x 600. I figured that you wouldn't bother to record at higher res than the screen had, so the resolution must be 1024x600. This seemed to work!
My stereo has absolutely NO branding on it anywhere so I don't know whether it's a clone of Huifei or something else, but it worked with the "Malaysk" firmware, which I downloaded from the Huifie file repository (linked from here), under firmware->Malaysk ROM->Malaysk DualCore RK3066).
I picked the bottom one (12th Jun 15, 1024x600 with different launcher).

I just installed the same unit. Only complaints are streaming music via Bluetooth only works if you open up the Bluetooth app (probably because android doesn't act as a Bluetooth sink). The other issue is, I cannot seem to change the brightness of the screen...its a touch too dim for daylight (I have a convertible) and a bit too bright for nighttime.
Glad to see you got a custom rom working.
Hey jcolebaker, do you think you could post what the LCD model number is? Is it a Hannstar HSD070IFW1-A?

Sorry not sure what the LCD is - I don't want to pull it apart. It has a board on the back which has the following on it:
BL-TFT-V2.2(HCT)
That's soldered to another board that says:

Update question
Do I burn the update.img file to the sd card or do I simply copy it? And does it have to be my gps sd card or can it be a spare blank one?
Thanks

Doesn't appear to be an img file in the context of "burn it" so I think that answers that question (just copy it) The head unit doesn't seem to do anything when I drop it in though (either with it on when I insert it or with it already inserted during a reset). Any thoughts?

The file should be "update.zip". I used a new SD card - try formatting one with FAT32.
You just copy it to the card and insert it - I think the stock Android image automatically checks for update files that look like this, and loads them. This process worked OK for me - if not then hopefully someone here knows more about the update process than me.
HI !
I also try to root my 2din android without success... I have the same as your and I fail to get recovery and the android can't detect the update.img (or update.zip)
I have tried many tips, my sd card is in fat32, well detected by android ...
Do you have the tip to access to the recovery ?
Thanks

I think the file is "update.img" not "update.zip". Anyway I have not figured out how to get to the boot loader on mine, and I never got any recovery console. Sorry I am too much of a beginner myself to suggest anything.

Instead of flashing a new image, go to the factory settings and type in *#hct#root#
This should give you root, no need to flash a new image

Bonjour.
If you would like more than root and you're still having trouble getting into recovery with your Hot Audio RK3066 1024x600 2 DIN Head Unit, the steps below have worked for me when the system does not automatically detect the mcu or update.img.
*** Prior to flashing any OEM or Custom ROM firmware, I recommend using a backup app like Titanium to save all your existing apps and data to your external micro sd card or usb memory stick.
1) Install Quick Boot or a similar apk from the play store.
2) Attach a wireless usb or usb keyboard and confirm it is working as intended. I use a Lenovo N5902 but most usb or wireless usb keyboards should work for this task.
3) Make sure you have the update and or mcu image file on your gps micro sd card or an attached usb memory stick (not the zip file).
4) Open Quick Boot, select recovery, and the system will shut down and boot into recovery.
5) Use your usb keyboard to scroll or arrow down to the update option with correct img file location, then press enter to execute the mcu or android firmware update or both.
6) After you update the android firmware, it is highly recommended that you go into the Settings > Backup & Reset, and select reset to factory and check the box to delete all data from the internal sd card. This reset to factory and internal sd card wipe should give your updated android system a clean start and help avoid system issues due to left over data from the previous firmware.
7) Delete the mcu and or update image from your external micro sd card. Done.
Hope this helps...
Best to all,

Why don't you just flash Malaysk's ROM? It's easier and the ROM is much smoother than stock.

By your username I assume you're brazilian, right?
Where did you buy your unit?
This night I've managed to talk to a Caska sales director for LATAM and he said that they cannot give the stock ROM for security reasons. I still have problems with the clock and the startup also (blank screen). They say their engineering team is working on fixing that issue, but China has a holiday that starts today (Oct 1st.) and only ends Oct 7th. So I'll only have an answer after that day.
Maybe you can talk to your seller and see if he gives any support (I bought mine at www.rcmultimidias.com.br).
Sure I am, you are right.
I bought mine from aliexpress. I found a update.img file in some folder, but I'm not sure if it is the full image. I opened that image in a linux box and looks like we have everything, there some ext4 images, boot image and a lot of other files, but I'm not 100% sure about it. May be somebody with experience could verify that.
Another annoying thing is the music and video apps not reading files from sdcard, they only read USB and inand. I've modified the Music app to point it to the correct path, but I couldn't install it back to the unit (It fails to install without any error). At least if I could reassign music and video buttons to another app, that would be ok (VLC is working fine, just need to adjust volume).

Normally you have to boot in recovery mode, something that I still don't know how to do for this unit, and then use that update.img to restore. See this thread http://forum.xda-developers.com/showthread.php?t=2660662, there some possible procedures there and may be one of them work for the caska.
How big is the update.img file they sent to you?

Yeah. I have tried everything but could not boot. It is just a blank screen.
Here you go with the update.img.
https://www.sendspace.com/file/mjkgfj
Here I posted a video with all the problems I'm experiencing with this unit. The main problem is that I cannot setup the right time, so all Android apps are useless (they require a secure connection to their servers and this is only allowed with a valid certificate [that needs the correct date]).
I was trying to root my unit so that I could use ClockSync to fix the time every 30 seconds (it resets after 1 minute), but had no success on that.

Hi!
So, where did you managed to talk to Caska? I've tried contact with Caska Brasil with no success (they say they do not offer support for Android units), and Caska Global didn't give any answer ([email protected]).
I've downloaded your update.img, but it's for CA712 and my unit is a CA380-XLA, I'm afraid to brick it. Have you tried entering recovery mode pressing reset and power buttons the same time?

I can reassign the screen buttons in my unit. In the settings, go to the last menu: "Shortcuts". Not sure if there's a way to reassign the physical buttons without modifying the original ROM.

I'm newbie as well, but I know that you must need possible clue, since you brick your unit. I'm afraid to point you to the wrong direction, but I believe it deserves to try. I saw some threads discussing about the bootloader and connect via USB. Looks like to have to install the usb driver for the rock chip (RK3066, since it is dual core and there is a file RK3066Loader_uboot_upgrade2_4_16gok.bin in the update.img file). I don't have more details on that, but may dig deeper.

I've tried pluggin a USB to the unit and connecting it to my PC with no success, no devices are recognized. I have developer mode active but no options to enable USB Debugging.
So, I was able to extract all APKs from the file danylam hosted, and it's quite different from my unit: I have only one "Settings" menu, and in my unit some essential apps weren't installed (like HBS_Carkit_ChangeLogoUtil.apk and HBS_Carkit_SyncGPSTime.apk). I've installed them and solved one of my problems: car starting with a GMC logo. But the SyncGPSTime.apk isn't being called by any applications, so it's not starting (and I cannot start from itself).
Then I tried installing the Settings.apk that came with the ROM and ended up with a non functional setup menu, unfortunately. Since in that version most settings are changed from the "Android Settings", and I couldn't install that apk (it shows me an unknown error), I've lost some essential menus.

This is the linux tool to open the image http://forum.xda-developers.com/showthread.php?t=2257331
command:
Code:
./imgrepackerrk update.img
It creates a update.img.dump folder and the bin file should be in the update.img.dump/Image
Boot.img is compressed and if you want to see content do this:
Code:
mkdir boot
cd boot
gzip -cd ../boot.img | cpio -i -

Tried searching mine but couldn't find any *.img files. But at least I've managed to uninstall the CA712 settings from my unit and revert to the original one.
Looks like your unit is a little bit different from mine.
Hello, my device says MCU has stopped and i can't touch on my screen to make factory settings
Can someone give me some help?
What do i need to download to make the reset?
I search for hours and hours and nothing.
Thank you so much
Tried this from erisin website
E0056 ES8990G(Android 4 Core HD V2.72) Stuck in boot screen or other problem
I read the instructions, and when i start the device with file in sd card, it does nothing
Ok
Touch is working again, i download some kind of LM software and its working
But now the screen doesnt retain anymore. and most of the buttons doesnt work
Maybe i just install some kind of rom for 2 din head units
Still looking for original software to install on my unit
I email Erisin but i don't think i will get any aswer, the costumer service looks very poor
Finaly spoke to Erisin
They say that the head unit is not from their brand
What brand is this? Can someone tell me?
Installed the wrong software on it
It works, android looks the same, but i don't have bluetooth option and button to move screen doesnt work
How can i delete this " rom " ?
Here's correct firmware of not Erisin "DR7090 1 din android car head unit stereo, Android 4.4.4.'', 1024x600 resolution.
1. Please confirm the unit is in "off" condition
2. Copy all files (not folder) into a SD card root, plug the SD card into GPS card slot, turn on the radio, it will begin to update automatically...
3. After "OK", unplug SD card and restart unit.
1721831 DR7090 Update.rar
I have the same DR7090 radio with the same firmware uploaded by demiro and I still have bugs to use.
Do you know the brand or if there is already more updated firmware ??
Or if there is some alternative ROM that works better ...
Greetings comrades!

sorry for my english from google translator
device:
quad core T3 All Winner-rom 16Gb DDR3 2GB-1024x600
Kernel Version:
Linux 3.10.65-Tue Nov 13
Os Version:
BSP 2.4.4.3.12-IVT-181113
Mcu Version:
20180911-1-KC1-24
I have tried to root my device by various methods without success, until using kingroot v4.9.6.151 and in one of the multiple reboots I have alone achieved a nice bootlop since it does not advance beyond the bootanimation of Android.
After many searches on Google and being very lucky, in one of my tests I managed to enter Stock Recovery through an external keyboard connected by USB.
but even doing a wipe data/factory reset and wipe cache partition continuos with the same problem.
so the only way out would be to reinstall the firmware through Recovery but I do not have it and I cannot contact the seller.
Could someone help me or give some information about a firmware compatible with my device?
To provide more information, I leave you some images that I took before trying to root.
greetings and thank you all very much.

I solved the problem I opened the recovery mod and I installed this rom
os_update_KC1C0101-N36-2.4.4.3.12_20190502_092902_b1
excuse my English translator.
thanks for answering I will try to test the same firmware. I'm glad that aya managed to solve your problem.now i am trying to implement bootable image via micro SD card using phonix card software.
I have managed to start an image of android 6.0.1 successfully although currently nothing else works no bluethoot, no music,no radio, no wifi ...
I also do not know if it is possible to access the flash memory from the bootable image through Phoenix card to be able to flash from the terminal the Boot.img of a 7.1.1 rom since I think that the integrity of my flash memory is still intact it is only damaged boot.img partition when trying to root. so maybe hopefully if I could restore it it would reboot.
I found a firmware compilation of allwinner T3 but I can't find one compatible with my device in .img format to be able to boot with softare phoenix card link here: disk.yandex.ru/d/07ru92rb3HEh73
Edit:
I have found and managed to flash the firmware os_update_KC1C0101-N 36-2.4.4.3.12_20190502_092902_b1
but even with problems android starts well and everything seems to work except the Bluethoot and the Wifi
even so so many thanks at least I'm already closer to the stock firmware.

everything is working just BlueTooth not working
Thank you so much for your help.
I have installed it and everything seems to work except the wifi and the bluetooth.
I have tried reviewing a system.log to find the problem using the liveboot.apk program and it highlights a problem.
in the beginning of android when starting the load of the wifi controller located in /vendor/modules/8723bs.ko it tries to read the file / proc / nec / wireless
and throws "file read error" so I think some memory paths nand
they are not reinstalled with the firmware and my device has corrupted memory parts.
In the Russian forum of 4pda.ru there is a lot of information, although I cannot translate it correctly, I am trying to find some firmware that will restore the partitions completely. See if I can get everything to work correctly.
at 4pda.ru they talk about a hardware way using the phoenix suite program and a complete firmware file in .img format

Thank you.
I have tested that firmware but it gave an error of 77% and I had no way to install it.
Finally I found in another thread information from the friend Ahmed68 and thanks to his valuable information I finally found a firmware compilation from the Russian website 4pda.ru.
As well as the procedure guide to flash the firmware through the Phoenix Suite program.
using this procedure I have flashed the Rom of android 8.1 and after finishing finally !! It has started correctly and I also have Root, Wifi, Bluetooth, Radio, Sound, Gps again ... Everything seems to work perfectly now and with Android 8.1 so perfect.

Greetings to all and thank you very much. We can give the thread closed.
Hi All,
I have a 1280x480 8227l headunit.
It was running android 8.1 and I had a few problems. I found a junsun upgrade on here I thought great!
It didn’t use the ‘update android’ button in settings as the instructions were to put the bin and upd file on a flash drive and reboot.
I did all this however the resolution is all wrong I’m missing a chunk off the bottom and the side is blank. I can’t find anyway to fix this.
A bit more google provided me a couple for 8227l firmwares for 1280x480 unit.
The problem is they are just zip files and the option is no long there for update android in settings? Is there a way to manually do this or something?
