Did you make a backup image?
[Android Head-Units] regeditaf:
No !! I don't have backup image
[Android Head-Units] kthejoker20:
Do you know the variant numbers of the machine you have?

Take a picture of the front and back of the machine with all the ports and post it for me.

Without a backup image of pretty much screwed but I'll take a look at your pictures and try and help.

If you want to donate the brick to me let me know.
[Android Head-Units] regeditaf:
do you the image
[Android Head-Units] regeditaf:
could you tell how I can enter recovery mode or wipe all data and reintall.?
[Android Head-Units] IIABODEII:
Tried that. Still not working. I am sure it's a software issue. I believe flashing another rom would solve the problem.

---------- Post added at 11:14 PM ---------- Previous post was at 11:11 PM ----------

Still not working. I did factory reset about 6 times now. Is there a way i can flash any roms to this? I don't care about bricking it or have a picture of a mustang in my SUV lol
[Android Head-Units] kthejoker20:
Your mcu settings might be messed up. That is a different OS from android, but built to operate together.

Go to settings yellow gear, then scroll to where it tells you the version numbers and stuff, right above the button mcu upgrade, place your finger on the version information, not the button, and hold it there for a bout 10 seconds. Then enter code 7890.

The other menu labled advanced has more settings, code 8861
[Android Head-Units] kthejoker20:
You have a completely different varient then being discussed in this thread. The firmware you flashed is not compatible.

The bad news...if your bricked now, you won't be able to enter recovery mode. The firmware also wrote a different recovery so that wont boot either.

There are 3 ways to unbrick it the way it is.

1. Your gonna have to unscrew and open the box. Look at the circuit board, post a picture here. Your looking for an sd card slot, ANYWARE...even check your monitor, it might be on the side or bottom. If you can find one, take a big sigh of relief. You can unbrick it. If you don't see one.... read on;. Basically, we can write new firmware to the sd card and easily reflash the system.

2. Somehow boot into the bootloader, but I don't know what your screen looks like, if you have any power or volume buttons to press to trigger that mode. If you can get into bootloader mode, you can then "pull" the backup.img from the device. Now, that backup image will not fix your problem, it will still be bricked. However, that backup image will have the original boot, recovery, and kernel. Then you can cross fingers and see if you can get someone to port a rom for you with those images.

---- The only other chance to enter bootloader mode is to connect a wired usb keyboard. Then power on machine and press and hold the "alt" and "prtscr" keys. Then press and release the "i" key. It should boot into rescue mode. Each system is different, so good luck....

3. The only other sure way to unbrick it is to find the debug port and JTAG re-write the chip. But this also brings you back to the original problem, if you can even do this, you don't have the firmware to write to it.

It is really important to read all the directions on this thread. It specifically detailed how to work with firmware. On these machines, the only way you can restore it is with a backup. There are just to many chinese wholesalers making thier own varient and finding the firmware is impossible. The only way you might have a chance at getting the original firmware is to email the seller. Otherwise, you will have to send it in for repair.
[Android Head-Units] IIABODEII:
I accessed that menu before. Tried messing with it carefully but no luck. I found two options that should fix my problems (Power key set + Backlight type) changed both options and restarted the unit with no results.

"Your mcu settings might be messed up. That is a different OS from android, but built to operate together."

This is actually very informative! I didn't know that. It all makes sense now. I thought the whole unit is only android.

I think you're right. I have a messed up mcu but i don't think it can be fixed with settings only, there has to be update from somewhere.
[Android Head-Units] kthejoker20:
to revert back to the old firmware

I'm just finishing up a test build for you to try out if you said you don't care about a brick I'll be posting it for you in a minute then you can try and see if it works for you be advised you have a super high probability of bricking your device if you use it but I need to gniuea pig
[Android Head-Units] IIABODEII:
Before i do it. Is my processor the same as the one being discussed in this thread?
[Android Head-Units] kthejoker20:
Looks good to me, slight variant but the firmware on page 1 will work.

But you do need to do a backup if you do page 1 firmware. It might break bluetooth and wifi.

This new build im posting is super experimental.

Anything could happen. Start with a build on page 1, see if it fixes your problem
[Android Head-Units] kthejoker20:
Also, put your backup of the system.img so i can extract the bluetooth and wifi to build other variants.
[Android Head-Units] IIABODEII:
Tried the stock oem shipped version in the first page, followed every step carefully. Got the prompt to install the update, device rebooted but i got (no command) screen. It stays for 2-3 minutes the reboots the unit and goes back to system normally.

Ps: it looks messy but i took the screen out of the unit for easier navigation.

I also took a backup of everything like you mentioned in red text in the first page.
[Android Head-Units] kthejoker20:
Please post your system.img backup. There are some with the same variant that didnt make a back up. Your the only one with those drivers for them.
[Android Head-Units] kthejoker20:
Try a factory reset first. Make sure every works first. Then try the upgrade again.

Its sounding like a hardware mcu is mslfunctioning.

Did you turn off usb otg in the advance menu? Both of the usb options there should be off
[Android Head-Units] kthejoker20:
You have to unzip the file, and only put the update.img file on the root or your usb stick. Also try switching usb ports.

Also, one more thing for you to try.

Install flashify to your unit. You will need to be rooted, so if not, download kingroot and root your system first.

Then install quick reboot (root) from the app store. Open flashify, and backup your current recovery.

Then download this recovery. Flash this recovery image.and then quick reboot to recovery. https://mega.nz/#!zxIgFRRY!T0XG3ZFdyE8hRyco6NJh5LmtwOR6F0JcY5xHxNeS0Lw

Let me know if the recovery loads. The robot will not be green, but a rainbow instead. If you see the rainbow robot, now try the update.

You may have to wait a minute or to for it to load, you will get a black screen normally.

If that recovery doesn't load, or you see black with flashes of white squares, power off the unit and reboot. Then reflash your stock recovery made in flashify.
[Android Head-Units] IIABODEII:
i'll post them tomorrow. My internet is very bad atm as i am using my phone's hotspot.

---------- Post added at 12:12 AM ---------- Previous post was at 12:06 AM ----------

they were on, turned them off, restarted then put the usb and got the prompt but it's still the same (no command)

i also deleted every file on the usb except the update file.

---------- Post added at 12:15 AM ---------- Previous post was at 12:12 AM ----------

i'll try that tomorrow and let you what happens. It's 2am here. gotta go to work at 8.
[Android Head-Units] kthejoker20:
Post your recovery as well. I'll see if I can patch it.
[Android Head-Units] IIABODEII:
Here is my partitions backup

https://mega.nz/#F!SVwmiDZT!bbNB5dPThVRoap1Ga-gD1w

isn't the file "recovery_backup_2017-07-01_17-19-01.tar.gz" the recovery file you're asking for?
[Android Head-Units] kthejoker20:
Ok, I got it. I'm going through it now.
[Android Head-Units] kthejoker20:
Going through your images, you have a slightly different MCU, however, you still have the same cpu and chipset.

Try the recovery I sent you, then see if it upgrades. If not, it's sounding like a hardware problem.
[Android Head-Units] IIABODEII:
Tried it. No luck. I got the same no command screen i had when i tried to flash oem shipped version. Appreciate your help.
[Android Head-Units] kthejoker20:
Just tested your images. My firmware is not compatible with yours. Don't flash anything here.
[Android Head-Units] IIABODEII:
Oh well. At least I tried :(
[Android Head-Units] regeditaf:
is there some one to help me ? please ?
[Android Head-Units] kthejoker20:
If you are asking those questions, dint mess with your radio.

This is not a standard android to flash things. There are 2 operating systems....

Thread clearly states, if you are confused, to stop and not continue. No support will be provided
[Android Head-Units] admfrlnd55:
Alright... To start off, I have not yet received my unit but I am excited for it and since I discovered this forum, I figured I would get started on following this thread.

I consider myself a pretty good modder and I have experience with Android rooting and flashing so knowing it can be done with this, I am all for it.

I ordered the 10.4" unit for my 2014 Hyundai Sonata. Since I can't confirm if my unit is compatible, I'll try keep the questions generic.

I have read through the pages on here and even on the Mustang and Fusion forum but of course they are talking about things specific features to their cars.

My first question would be about Kingroot. I've seen both not to install and here you mention using it. How safe is it and what are the benefits of using it?
[Android Head-Units] rem1969b:
Help!

Good afternoon! At me such problemma, the device has ceased to be loaded! Is constantly on the animation load and then does not load. I tried to enter the recovery mode using the keyboard, but there always appeared a robot fallen! And then again the animation, help solve the problem.

You sir, should not have attempted to do anything in this thread. I can tell you lack the knowledge simply by your picture link.

There is nothing we can do for you here. Sorry.

Hi

I am using exactly the same device but with android 4.4.2 and have some questions?

1- When i use any player app other than one shipped with device (like poweramp, MXPlayer) only front speakers work and back speakers is silent ???

2- Time is getting updated from GPS but it 1 hour past the real !

3- how can i change the desktop wallpaper?

4- and how to change the boot logo?

Regards
[Android Head-Units] spicemaster:
All these links are dead.

Someone who's downloaded these files, please share them with us.

Atleast the version 2 rom and the custom recovery

thanks a bunch
[Android Head-Units] spicemaster:
dude, please check your PM.

Have explained myself there.

now all i hope for is a a chance to try your ROM... i think my unit is compatible with your sources... so it shoudl work... even if it gets bricked , i will still be happy i tried.

pleazse dude...
[Android Head-Units] hadak:
where did you guys buy your units? Any reliable seller link please?
[Android Head-Units] kthejoker20:
the download links are broken. I'm working on fixing them
[Android Head-Units] ikuznets222:
Very nice, you're back, really as this seems to the only alive thread on the subject at this point. Is there any chance you'll be releasing your your modification procedures for those with similar devices but who're not able to flash your modified firmware directly? I'm yet to receive my unit but hopefully I can help in some way like modifying system apps.
[Android Head-Units] kthejoker20:
unfortunately, no.

However i am modding my toolbox app to include the modifications / customizations. I cant post it to the app store. Google doesnt seem like other apps deleting thier binaries....lol.

Too much danger by me posting shell commands and decompilers etc... so i will stick with the app for now.

I am working on controlled release though. There are a couple of guys trying to exploit my work for profit.
[Android Head-Units] ikuznets222:
Anyway, thanks a lot for what you've done already. If you share at least how to root this headunit without going Kingroot way, or maybe if you know how to get into the recovery on non-loading devices - that already would be more than generous (and safe in any respect I think).
[Android Head-Units] kthejoker20:
Be very careful, the recovery is not the same like other android devices, even though it may appear so.

You simply cannot just flash things in the recovery.

Once you get root, install flashfire from the app store. That is the close to a normal recovery you will get for these rockchip devices.

You can flash like normal through flashfire. Beware, if you mess something up, its not forgiving and you cannot flash an image. Very few have gps sd ports and "possible" to recover, but slim. Unless your good with a solder gun.
[Android Head-Units] ikuznets222:
Flashfire is interesting but seems only reachable if the device is fully loading to UI. What if it's not loading after modification of something critical like EventCenter.apk. What I meant was - is there any way to jump straight to standard recovery that comes flashed on device? Like holding reset or shorting key1 to ground, etc.

Black screen after update

I tried to update the head unit for my fusion but after i finished i got a black screen .. everything is working with touch but i have a black screen

I didnt make a back up and i need to revert back to stock but the links are dead ... any help ??
[Android Head-Units] kthejoker20:
help is going to be slow going. i have other priorities right now. no donations coming in and everyone wants help and updates for this thing.

Frankly... everyone says they will contribute... but there is nothing.

no motivation to really continue with this project.
[Android Head-Units] kthejoker20:
Got Dolby ATMOS, DTS, and Beats working.

Pretty awesome
[Android Head-Units] masselo:
It is great following your development and see what is possible with this unit. I have a similar unit in my Ford Focus, seems to be the same hardware inside.

I don't need new function as i'm happy with the build-in possibilities....but time problem sucks. Is there an easy way fixing this Problem? In your changelog of V2.0 i saw you have solved this problem?
[Android Head-Units] kthejoker20:
sounds like you modified your build.prop improperly

Don't mess with that. This is not a normal android system.

I keep saying it over and over but no seems to listen

You simply cant "flash" things in these devices.
[Android Head-Units] masselo:
You get me wrong. I didn't do anything. It seems to be a factory issue. They told me to set timezone manually one hour off, to solve this Problem. But it sometimes does not work.

As i saw your changelog with "time Problem fix" i thought there must be a way to solve this issue.
[Android Head-Units] crator1349:
damn, I wish I saw this thread earlier. I followed another post saying to use KingoRoot, which I did to root my device.

I was having bluetooth audio problems BEFORE the root, hence me trying to get root to fiddle around.

What are my options here to remove the root? I assume asking the re seller for the stock OEM rom is my only option?

I have the ZXW rkpx3 model, but it's a slightly different variant. pictures below

- Anybody knows the default password to access the advanced settings!?

- Anybody knows what things we can change in the advanced settings?!

- heated seats issue. anybody solved this ?!

- voice commands lost.... Any solutions?

- No actual recovery mode access.

- download links are not working !?

Any answers ! to be encouraged to donate.
[Android Head-Units] ikuznets222:
1) - Anybody knows the default password to access the advanced settings!?

If you share your firmware I can pull them out of the code. I'm not sure yours is the same as the ones I have firmware for.

2) - Anybody knows what things we can change in the advanced settings?!

They could vary depending on which customer.xml is used or which car model is selected. You'll see for yourself once you have the codes

3) - heated seats issue. anybody solved this ?!

What exactly is the issue?

4) - voice commands lost.... Any solutions?

What voice commands are you referring to? This feature wasn't advertised where I bought my unit

5) - No actual recovery mode access.

True. We must experiment to find it. Shorting KEY1 to ground or holding reset are example starting points
[Android Head-Units] jmobai:
Many Thanks

Please take a look at the attached files . you will find my info.

for heated seats, I do not have this option on my touch screen. I need to activate it .
[Android Head-Units] ikuznets222:
ОК, you have a slightly different version of this headunit. But you can try advanced settings code from my firmware: 8861. Others you can try 1688, 666888, 8888. If those still don't work I need /system/app/NaviSettings.apk from your firmware to see the code. In advanced settings you may have to change you car model to get what you want.
[Android Head-Units] Sleer:
Plz HELP!!!!!!!!!!!!!!!

if someone has working links to the specified firmware especially stock and version 2.0, I will be grateful.

Yesterday, when updating the firmware, I did not pay attention to the screen size and caught the brick. ((\

[Android Head-Units] jmobai:
Thank you

Anyone has the wiring diagram for this unit ?!
[Android Head-Units] kthejoker20:
If anyone has the old firmware, do not load it.

Those were dirty ports just to get the ball going.

I have a new build coming out. Still experimenting with my custom recovery. I'm having mount issues.

Should solve most issues with WiFi, heated seats....etc.

Major performance increase as well. That px3 chip is actually not that bad.

Time is fixed as well.
[Android Head-Units] ikuznets222:
Any clues for people with slightly different units where to start with their custom recoveries? Also how do you get into it - reboot recovery from main UI, or there's still some physical way to force it into recovery?

What were the issues with Wifi? My observation so far is that it's sometimes slow as hell but generally stable. There are drivers for other wifi chips in firmware but I haven't yet tried compatible USB wifi dongles..

A more complicated ZXW

I don't know if this thread is still active. I would like to contribute . I own a 2013 Cadillac XTS Platinum. I bought this radio. It was sold as a direct replacement. upon studying the unit its a ZXW variant. looks way different than what was posted earlier. Obviously the manufacture has engineered more complexity to the unit than what i have seen before.

10.4

1gb

32gb

Android 4.4.4 (says 6 its not)

I would like to work with ever is continuing the work here...or if i can purchase the rom, i am willing to do so.:good:

Has anyone tried an alternative method to kingroot? like Kingo root or similar?
[Android Head-Units] ikuznets222:
I used latest KingRoot on mine. It said it failed but I checked in terminal it actually succeded. Immediately without reboot I installed supersu, uninstalled KingRoot, then run Supersu app and agreed to an upgrade. After reboot I had perfectly rooted system without any trace of KingRoot.

What exactly did you do to get UI like on those pics #8 and #9?
[Android Head-Units] hgreen70:
It actually came this way. It's the console for Cadillac cue. Within the Hu there is a console apk that connects to can bus and mimics all of the original functions.

I used king root the apk from apk mirror, everyone says don't use it. But I have not had numerous problems!
[Android Head-Units] ikuznets222:
Interesting.. Up to this point I thought every firmware had the same apk listing.. Could you please point the apk name? Everything else seems to match mine, other than it's for European Mondeo, and it's fake Android 6.0.1

Console. Apk

---------- Post added at 04:24 PM ---------- Previous post was at 04:22 PM ----------

The firmwares are very similar on all of them because they are android, however there a few differences made on model.
[Android Head-Units] ikuznets222:
Console.apk - mine doesn't have it. Is it possible for you to share it? Interesting to look at the code - maybe I'll find some stuff for other cars there, the name seems generic.

Yes, sure all of them are android ) but for this one - we can be pretty sure it works on all Teslas.
[Android Head-Units] hgreen70:
When I get to my office I'll share the apk, I am pretty sure if you don't have a Cadillac it won't work, but I'll share
[Android Head-Units] pablomaes:
OK thank you very much. I'll try. I've mixed the customer files trying to get the different themes aviable; my unit only lets me choose the default theme. If this works for me ... I'll try to play a little with the apks.

Is there a way to take off system bars from top and bottom to enable full screen
[Android Head-Units] pablomaes:
I had a small problem with kingroot, after installing it and running root, it said it had been done correctly and immediately after the screen went white (not black, white) and the system froze.

I had to restart.

I checked that the system was effectively rooted and I tried to install supersu, but at the end he tells me that a process blocks it (imagine some kingroot restriction).

The funny thing is that, it is assumed that esfileexplorer has root permissions, but when I try to add a file in / system / app for example, it gives me an error. ?

Of course it does not let me uninstall kingroot with normal means.

This afternoon I will try other ways to uninstall it.

Any idea why not let me edit system files with esfileexplorer?
[Android Head-Units] ikuznets222:
Theoretically, as these limits for screen areas are only set within the launcher, you can install and use your own launcher.
