As there is no custom recovery for this unit. Thus typical nandroid backups are not possible with these units. So we had to use the unix command "dd" to copy the partitions to backup files. These can be rebuilt into a typical update package, but I have not gotten into that myself yet.

Here is a DPI changing guide: HERE

Hi,

Do you have any idea how to Hard reset my R16 head unit with no physical buttons?

its stuck on the boot image.

i tried to update/reflash the firmware by coping the files to the root of my SD card unplugged the head unit and plugged it again. but it didn't work. it did update just stuck on the booting image!
[Android Head-Units] velvetpig:
From Eonon, This is for Android 6

Please download the upgrade file from this link:

https://drive.google.com/file/d/0BzzboUgP8pRta2dWdHNWYmRmdU0/view?usp=sharing

Instructions:

1. Format a USB to FAT32 first, then decompress the upgrade file and only copy 4 files to this formatted USB.

2. Insert the USB to the unit's USB slot.

3. Turn the key to ACC level.

4. Press the RST button on the left of the panel, then turn off the key at once.

Then turn the key to ACC level again after 5 seconds.

5. Then the head unit will upgrade automatically.

You can refer to this video:

https://youtu.be/oLm4o0PESSo

Attention: Please do not cut off the power and take out the USB during the upgrade. It may take a long time to do the upgrade. So please be patient. And please follow the instructions strictly.

This worked for me with head unit stuck on boot screen. I am pretty sure this is not a hard reset but it should get you going again.

If it does not go to update screen try another usb plug. It didnt work on first usb plug i tried. But the second plug did.

I have 2 usb at back of unit and a mini usb at front.

Good Luck.

Forgot to mention,

QuadCore-R16 (astar_d7)

1024 by 600

7 inch screen

The radio after bootup has no sound, I have to change band FM to AM and back, Then it works.

The hard buttons don't light up but with headlights do.

If i try a factory reset i am asked for a password, I know about the others but i have not seen this one.

Any ideas.

You need to boot to recovery mode and do a factory reset from there. Since u cannot boot to adb or terminal, u need to do the USB keyboard trick.
[Android Head-Units] pir8man:
Thank you velvetpig! I updated to the system you posted to google drive. and then installed the latest EasyConnected app and I finally have mirrorlink working on my LineageOS based phone. That is a first for me.

With that everything is completely different now, lol.

Easy Connected support was happy to supply an Android 7.1.1 compatible version. They also informed me that there was a known bug in the android 6.0 system that was affecting the programs operation. They recommended I contact my vendor for a ROM update. Which led me to testing the various ROMs I found on 4PDA forums (while waiting for a response from EONON support). Alas none solved my mirrorlink issue, but the update velvetpig posted apparently had the bug fix and when I loaded my updated EasyConnected app for testing, I was pleasantly surprised with my first phone to car stereo mirrorlink connection.

I will also note that flashing from another ROM back to EONON version caused my hardware buttons to stop responding again. I rebooted to recovery and did a factory reset to resolve the issue. Everything went smooth after that. A clean root via kingoroot. installed and updated my desired apps. I am set to learn how to use mirrorlinked setup for the next few days.
[Android Head-Units] velvetpig:
pir8man

Good to see you had success.

When you say " I rebooted to recovery and did a factory reset to resolve the issue " how did you do this?

Was this using UNIX ( will be researching ) or some method i haven't seen yet?

I can get to factory reset on the System screen but dont know the password.

Cheers
[Android Head-Units] pir8man:
as my unit was operating correctly, I installed Terminal Emulator from the Play store. Then opened a terminal windows and typed "reboot recovery" on the command line.

once booted into Recovery Mode, I used my USB keyboard arrow & enter key to run Factory Reset and Reboot.

I have not found any other way to interact with the recovery on my unit. A USB keyboard is necessary. It also makes typing terminal commands much easier. :)

EDIT: did anyone even try the posted passwords for the settings based factory reset?? Mine just reset using "7890" (developer password).
[Android Head-Units] pir8man:
It is possible you have an empty recovery partition. Ouch! And now you have a damaged data partition. That is unfortunate. I read enough to know it can be reflashed. But you are beyond my current knowledge.

Good luck!

Congratulations! Now you can install the latest firmware V7.3.2_20170826.102252_KED1-mod, after installation, make a factory reset.

Any way to enable Bluetooth from USB? I have tried 2 USB dongles now and neither are getting used for Bluetooth but the module is seen in the console and USB Host apps.

I want to use an external USB Bluetooth module for connecting to my OBD Scanner and running an OBD app I have for my car, 2016 Mustang GT.

5. The kernel is added support for running scripts from "/system/etc/init.d"

6. Added com.tw.fcam (DVR) to the system applications.

Hi, I did update my system with the regular verison not the mod one (V7.3.2_20170826.102252_KED1) and everything went fine (I had previous KED1 version from April) but I have lost Bluetooth.

Basically I don't see anymore the headunit on bluetooth from my iPhone.

Any idea about what happended and how to solve it ?

Is there any new update for KED1 (Kaier) which solve that ?

Many thanks

Actually I had the occasion to give it a try few minutes ago.

Found the right setting, just that I had to unchecked BC8 in order to have BC6 checked correctly, but after no change bluetooth still not there.

Do you have the meannings fo all these settings (BC6, BC8 and others) ?

Hi ****, thanks I saw one of your previous post explaining that, so I tried 15min before the three options without good result.

I tried as well after selecting an option to switch off and restart the headunit, check if the selected option was still there and try to look on my iPhone if I can see it or not and even vice versa using the bluetooth app of the headunit to look for bluetooth devices.

unfrotunatly none of these tries were successfull.

Well, this morning I think I have found the solution.

Even if you enter the bluetooth stock application is not really turned on, you can check if you enter in change name and password, if nothing appears is that the bluetooth is disabled

I have installed a playstore application, it is only an activator on off

when you put on and if it appears change name and password and you can connect the phone.

You know a better application than the stock, the stock has no agenda search engine and is quite basic in everything.

even if you reset those options if you have changed them, they do not change.

I read in the forum furgonvw that you have to have the options well placed, not only the bluetooth, for example, if it does not have dvd, have marked not DVD, no recorder, etc.

As I can not put links, I send it to you privately.

Then if I can upload a photo with my settings.

EDIT

So I have it and it connects well

you have to look at the options according to your unit have dvd or not, etc

Go testing, every time you change something restart
