[Q] 2DIN 'S07' Android 4.4 Using RK3066 - Root?

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:
P/N:BL-7inch-7000-KB-V00 20150311

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,
R

Android dvd s07 update
Hi,
I want update my android car dvd mercedes w203 2006

Xtrons TR771L (Allwinner T8) updates (was: Xtrons TR771L Radio app freezing)

I had this unit for some 2, 3 weeks now, and while it worked great initially, all of a sudden the radio app started acting up.
It starts with some garbage displayed (e.g. 'jV!fxcj') instead of radio station name, and it is not responsive at all. If I manage to get to home screen or to anywhere else, it will just pop back up to the front, and it keeps happening constantly, Sometimes, after doing who knows what, I manage to kill it, and I can use the rest of the head unit, but that happens rarely. I also tried going to the settings -> apps, and killing the app from there, but it doesn't help.
I hard reset the unit, and the radio worked fine for about five minutes, and then it started happening again. Is there a way to at least disable the Radio app somehow, so the unit is usable in some capacity?

I have exactly the same issue on my TR771L. I got an MCU update link to load onto an SD card but haven't been able to get it to install on the unit.
The looping is really annoying especially at night.
EDIT:
Android version 8.1.0
MCU version T8.3.19-36-10-E53201-180726
System version V9.3.1_2018082.102205_MLT5

I had that problem too and did an firmware update and it seems to be ok now

This might be a stupid question, but where do you get the firmware update from? Is there a custom ROM to be installed on it as well?
I was always confused by many similar but different headunits, and was never sure if something would work on mine or not. Is it PX5? Is it MTCE? Is it none of these? Sigh.
On a positive note, it seems to work better now. I uninstalled the automate car dashboard and know it happens rarely if ever, and even when it does, a hard reset with a pen solves it.

Well, I contacted xtrons with a request for the update file, and they provided a link - https://1drv.ms/u/s!AjrY0uqbW_kBk36dRnJD4d_aaej8
This is a system update file, and after I went through the versions I have are:
Android version 8.1.0
MCU version T8.3.19-36-10-E53201-180502
System version V9.3.1_20181012.103419_MLT5

You need to extract the files from the RAR file, put them on the SD card or USB, connect it to the head unit, go to Settings -> Car settings and then scroll down and choose MCU update or System update. Depending on the file you got, it should detect the update files and ask you if you want to reset the sd card/usb (I choose no just to be safe) and it took a bit of time to update, and the start loading animation (xtrons) took a bit more time than usual, so don't worry about it.

Collection of 8227l firmware (android vers:6-9)

https://m.youtube.com/watch?v=FLe7yx3XJP8https://m.youtube.com/watch?v=FLe7yx3XJP8
click video link and comment. im not a developer i just listened to the amazon sellers directions and then searched 8227l in google and found a bunch of files, then tested them and now i want to pass the info on.
tp the guys asking if itll work?
i dont know you gotta test it like i did. they worked on my unit. and the files i donloaded came from other style stereos with android.
i just generally think they are all same firmware if it look similar to actual stereo design and ui .

This is what I have.

Can i install the 9.0? Is is real 9.0 or fake?( you know right now it has 6.0 but says it is 8.1GO)

its the fake 8.1 like always but it works so cant complain.

Is this the 8.1go or just 8.1?
Also the android 9.0 has multi screen working?
Can i safely flash my head unit with the firmware listed?

Yes u can ( always do at your own risk like me); but use one of the touch only files. I can't upload pictures yet but i tried to post a screenshot of each firmware look. If its 8227l firmware it should update/flash.

Ok i may try to flash it this few days. Btw the 8.1 is the go ver or just 8.1? What is your recommendation to install 8.1go or 9.0 which is smoother and better?

They both looked very smooth even when running on my stereo. And i have a touch & button stereo it worked flawlessly no lag no glitch.
Only error was for the firmware being for touch screen only

Hello, I would like to know if this type of software has in some menu the option of autosleep to program that it turns off completely and does not remain in standby, in other Android it exists but here I do not see it. Can this Android 9.0 image be flashed even if it now has 8.1? Is it official or is it rooted?
thanks

i have the following head unit in the link attached will android 9 rom support this head unit ? It has touch button such as back,home,volume up/down.

Hi guys! I ask for your help, a few days ago I bought an android radio unit on aliexpress, specifically the Junsun brand, with these characteristics:
Model: 8227L
Android version: 8.1.0
Kernel version: 3.18.79 (gcc version 6.3.1 20170404 (Linaro GCC 6.3.2017.05) [email protected] #57
Comp. Number: alps.mp.o1.mp5
2GB Ram
32Gb Rom
7 inch
With Canbus (ford mondeo 2007)
Its my first time with an android radio unit and I am very lost, I would like to know if I can change the firmware or update it, the one that it brings is very limited and does not let me change the brightness of the device or bluetooth functions.
Thank you for support!

Hi guys!
Is it suitable for me?

From lots of research and emails to the company, i found that these Android stereos come in many brand names but run the same 8227l system. Another company with the same unit is joying but the device name is different along with the entire UI. Please do be sure you have a 8227l unit before proceeding. Other updates for other brands can be found on google and xda forum. I will try to remember to put link for xda forum. Below I have listed 2 groups of files. One is for touch screen only android stereo and the other is for touch screen with volume knob. Please choose according to your type of stereo. And follow the steps below exactly.
1. Download proper zip for your device.
2. Extract the 2 files from within the zip folder.
3. Copy & paste the ( .bin ) & other file on to a blank sd card or usb flash drive. Make sure these are the only 2 files on the sd card or flash drive.
4. With stereo unit powered off insert the sd card or usb flash drive and power on stereo. (Note some units will recognize the file immediately during boot, and others will prompt you after loading main screen. If unit does not recognize it, power off for 40sec and when u power on tap the screen in middle repeatedly with finger until the word "detected" shows in green. If it gives a message in red saying failed please check you have good download copy and have followed the instructions exactly. Will answer questions as i am able to.

TS9 - sp9853i

Hello, I have bought a chinese head unit without a real brand but the only thing that I know are the processor type "Octa - sp9853i" and the MCU version "Ts9V.4.3-156-80-A46181-190731". I have had problem to connect the Wifi and often it didn't work properly. I sent an email to the seller and I sent me an update to the next version.... I have installed it but now my unit doesn't work anymore... it is stuck to the first "opel" screen and Android doesn't run anymore... Any idea how I can restore it? The physical reset button doesn't work. Seller is not replying anymore more. A massive thanks if someone can help me.

Not an MTCx unit, requesting thread move to Android head units.

Hi. I have received from the seller some files to restore it. I solved the problem but WIFI still not working. I read that there is an app that could fix the problem. The app is 'DF TetheringFIX' but the root is required. Does anyone know the procedure to root my device?

upload your firmware. maybe it is possible to root.

I have update the firmware but I still have problem with the WiFi in Tethering. It is so weird. Sometimes it goes very well, 30Mbs... But often nothing at all. I need to reboot and reboot times and times and if I'm lucky I can get connection... But often it doesn't work. I don't know how to solve this but it is very frustrating! Thank you

Allwinner T3 P3 headunit failed update.

Hello all, i have tryied to update my headunit to android 8 using PhoenixSuit, the upgrade process had gone right, but the headunit locks on the android start screen. And i am struggling with it for some months now.
I am unable to make it be recognized by phoenix suit again, nor make it boot to an USB or Mem card made by phoenixcard.
the only thing i could get was it to start in recovery mode, so it read files like:
51eb6df0-cad7-11e8-bf31-afdca4ac0826
52c7b3fa-cad7-11e8-8188-57adc8d05072.0
52c7b3fa-cad7-11e8-8188-57adc8d05072.1
etc.. the name of the files vary according to the "uboot" file i load on the headunit.
I have tryied lots of files gotten from russian foruns, etc to no sucess, even the original files that i got from the maker fails to start the unit.
If i had to guess the problem that make me unable to restore the original android 7.1 i got from the makers, it would be the partitions number and size, i think phoenixsuit had recreated the partitions in the upgrade process and that recovery mode does not change it... so any android that is not the version 8 (that seens to not work on my unit) does not get even to the start screen.
If someone can give me some tips on how to solve this, i had alread tried anything i could understand from the russian foruns and from here to no sucess
Thanks in advance.

So nobody knows how i can get into a "command prompt" mod where i can remake the system partitions or how i can get the headunit to boot from a phoenixcard created USB?
