Ebay Android Head Unit won't boot - Android Head-Units

Hi All,
Wondering if someone can help me.
We have an Android head unit installed in our pajero, purchased in about june 2015, its one of the generic units that was sold on ebay at the time.
Pretty sure it was running Android 4.1.
All of a sudden it has stopped working. It powers on and the "Mitsubishi" symbol comes up and flashes, but that's all it does, will not go any further and boot up. Reverse camera still functions.
Is there a simple way i can reload the system hardware back on it or give it an update in the hope it will come good?

Anyone?
Would be happy to pay someone in Aus who could provide some firmware for my unit on a SD that would get it going again.
Cheers

Thankyou for that link.
I carried out the Recovery, factory reset/clear data/cache as per that link and our unit now works again!
For the record it has the Kitkat 4.4.4 Android operating system, was able to see that now i could get it booted up.

Hi .. what model Pajero
Did you originaly have just a radio or the MMCS GPS etc
Cheers

[HOW-TO] How to flash a factory image / return to stock / unlock / root #
It includes steps to fix the half storage issue.
If you want to check immediately before doing the above walkthrough, power off your phone completely, hold the volume down button and power on your phone to get into the bootloader. At the bottom of the screen, next to"Variant", you should see either "mako 8GB" or "mako 16GB". That tells you the storage size in the phone. In your case, it should say "mako 16GB."

Since you're new to the phone, I highly recommend reading that thread I posted a link to earlier to set everything up on your computer and phone, which also includes how to fix the wrong storage size issue.

You could try using wugfresh's toolkit to install the factory rom.
That's about as simple as it gets.
If you can't do it using the toolkit, then bring it to someone/some place that can flash it for you.
I would do it if I lived near you. The hardest part is the computer setup, imo, just getting the proper drivers installed but even that is fairly easy to do using the toolkit.
Good luck.
Can you just return to ebay seller? It's not as described and you paid for 16gb without this additional work. Possibly it's a listing error and actually is a 8gb?

It is a 16GB apparently, just the OS needs to be reflashed to fix the misreported space.
just clear the damn cache on stock recovery.

Factory image will fix it assuming you can flash it. The toolkit can do it or you can use fastboot commands. Whatever you prefer

Hello...
Read this post: https://forum.xda-developers.com/showpost.php?p=71805763&postcount=343
If your device is in the state described in this post, it is likely dead. You need to RMA your device.
Otherwise if your issue is different, answer a few questions to help diagnose the issue:
What happened..?
What did you try to fix it?
What build are you currently on?
Is your bootloader unlocked?
Do you have access to recovery yet?
Good luck...
If you aren't in a boot loop of death you should be able to fix your phone by doing a factory reset. Power down your phone by holding down the power button. Go into the bootloader menu by pressing power and volume down at the same time. Use the volume keys to find the factory reset option and select it. Good luck. I'm pretty sure all of these phones will permanently boot loop at some point because there is a serious design flaw, probably with solder that can't withstand the heat the phone generates like on the LG phones. Hopefully your 6P isn't there yet but flashing an OTA frequently triggers it.

Hello... Did it start bootlooping after a 7.1.1 OTA? So you unlocked your.bootloader? If yes, it wiped all your data... And now your phone still bootloop right?
Then reboot into recovery, press power and tap volume up when you see the Android guy laying.
From the menu, select factory reset. Try to reboot and see.if that helps.
If it still doesn't work, try to flash a stock firmware from here: https://developers.google.com/android/images#angler
And extract the zip a d open the folder
Reboot into bootloader. From here, openn the flash-all.bat and let it install the new firmware. It will reboot when it's done flashing.
Hopefully a factory reset will suffice to solve the issue. Let us know if it works... :good:
Good luck...

Hello...
Sorry to read that. Only way now seems to have your phone repaired. I don't know if you're still covered, but don't let Google or Huawei charge you if your warranty is already ended. The issue is well known and you shouldn't pay for their mistakes!
If you don't get a positive answer from the first person, tell him/her you are going to think about it and end the call. Call back one or two days later. You'll likely speak to another tech. Retry as much as needed. A lot of people who insisted have had their phone repaired/replaced for free that way. Try escalating the case to a supervisor if needed. Don't give up until you succeed, because that's all they are waiting for!
Sorry again, good luck...
My phone is out of warranty

I've seen someone saying some people send their device in China to have their SOC/processor replaced. You know those are soldered on the motherboard right? Unless you have the right equipments, it's really unlikely.

Boot loop on EONON GA7165s

Hello,
I got my Android unit to boot loop. It reboots on the "Optimizing app ..." screen.
I found out how to make it load files on boot from SD card (key combination), but I don't know what to put on the card.
The problem is that I don't know pretty much anything about the unit, except the official specs.
How I got to this point:
1. Tried to root with kingoapp.com - didn't work.
2. Rebooted successfully and worked after that.
3. From Settings -> apps -> system I disabled Google system app (foolish, I know...)
4. Now it reboots on the "Optimizing app ..." screen.
Please suggest how to fix it.
Thank you!
Here is my conversation with Eonon support.
Hello,
I installed bad app on my head unit and now it can not boot. I shows "Installing apps 15/16" and then back screen and restart.
Please suggest how to fix it.

Hi. Can you tell me what is the kye combination for this model. I have the same problems and the same talk with Eonon. They suggested to bye new radio.

It turns out that the unit has Recovery mode.
You must plug in real PC keyboard in one of the USB ports and press Alt + Print Screen + i on boot.
Try both usb ports and google the combination if it's not working, it was a long time ago I'm not 100% sure.

By the way, when mine went into boot loop I replaced it with a stock BMW Professional (with Bluetooth) and the audio quality improved significantly.

"joying" radio stops after sleep

Hello!
I am a total noob at this so please forgive me if I don't give the correct information.
I have searched for this.
I appear to have successfully rooted my ebay head unit with this firmware. It is a Sofia 3GR, 2GB ram, Android 6.0.1.
https://forum.xda-developers.com/an.../rom-gtx-joying-stock-rom-2018-01-29-t3742482
Works Great!
When I remove the key from the ignition and leave it for 2 minuets the radio will not play/resume at all.
I have to go to go settings/apps/ radio and force stop it every time I want the radio to work.
The radio just started doing this BEFORE the firmware update. I thought it would fix it.
So looks like another one of those noob posts that no one can answer.
I have done more searching and found a few options.
There seems to be a "kill app" system on standby?
But I don't know if this is possible to change.
Replace radio app with another one?
I don't know which one will work
I am also struggling to put the Joying firmware back on.
Or buy another head unit. I have done this but still want to fix this one.
But also have to wait 2 months.

2 minutes? or longer?
The Sofia takes 4 minutes to fully close down to deep sleep. So yes, if you do this within 2 minutes you might have that behavior.
If you do that after approximately 4 minutes it should behave correct.
That is on the default ROM.
The gtxaspec ROM has Xposed. Check if Xposed is active.
As far as I can remember it comes standard with the XSofia Xposed module which I wrote for the most part. If not it might have the stand-alone nokill mod.

I can confirm defiantly longer then 4 minuets as well and the radio ill not play after that.
Apologies but there is where I am more of a noob.
I do have an Xposed app on the head unit but am unsure of how to use it.

Do not underestimate your skills or overestimate mine.
By default all apps are killed, apart from a few very important ones. The radio app is not one of them and will be killed upon ignition off.
I really don't have a clue why it doesn't work for you.
You should be able to reflash the Joying firmware. The gtxaspec software uses a modified twrp recovery image, but after flashing the default Joying recovery is flashed back. Simply to make it possible to always go back to the Joying one.
- You did use the Custom.apk to prepare the unit for flashing the gtxaspec unit. Use this same app to check if you have the default Joying recovery in place. If not, use the Custom.apk to reinstall/reflash the standard Joying recovery.
- Which firmware version do you try to flash back?
- If the standard Joying recovery is in place and you have the correct Joying firmware, then please use a needle (or so) to reset the unit (RST pinhole). When the boot logo appears, reset it again. Do this 3 times. Then the leds will flash purple and your unit MUST start to reflash from usb-stick/SD-card.

For Joying firmware:
RESTORE STOCK
VERIFY RECOVERY
REBOOT (Just simple reboot to Android)
Insert Joying firmware
And if the screen stays black or you stay in a boot loop: Use the triple reset option.

Do you have the stock recovery on your system?
Did you get the purple leds? Note that the purple leds means "3 times unsuccesful boot. forced flash". It will not nicely reboot afterwards.
Did you put in the USB-stick/SD-card before reset? If there's nothing in the slots, it can't flash of course.

1. Do you mean using
RESTORE STOCK
VERIFY RECOVERY
to get it on my system? If so then yes.
Your steps helped me get further this time.
2. No purple led's installed in this head unit.
3. Yes.
Should I used another firmware?
Should I try reinstall the GTX firmware?

2. Sorry. I meant hardware buttons. They have leds which are normally set to a color, but turn purple after 3 incorrect boots. But if you do not have hardware buttons ....
Which firmware are you trying to flash? Have a link?

First of all: The first post in the gtxaspec thread mentions "you must be running Joying 6.0 firmware dated 2017_12_15 or later to install this ROM".
Were you doing that? And if so, why is your MCU version still 5.25?
If you have applied that firmware version for MCU version < 5.25, it will update your MCU version to >9.20.
I guess you can't check right now on the MCU version, but the next time you flash you need to take the "MCU version is 9.20 or more later" firmware and try that one.

Yes you're right. It was 9.20
Before that, back when. I couldn't figure out the MCU versions and what I should use. So I closed my eyes and tried both and both worked and both solved issues.
So I did upgrade to the GTX from 9.20
OK let me try 9.20.
9.20 boot loop solved!
:laugh:
Jy firmware installed!
Will currently running in inside on a test rig. Will install in the car tomorrow.
Update!
The head unit has been in my car on standby for 2 hours and the radio still works! I will test it longer and over night.
This issue happened before the GTX so I might try go back to that.
I was dumb and put 12V on the right amp channel blowing it up so looking at a replacement amp.
Thank for putting up with this one @ surfer63!!
Much appreciated!
So another update.
If I install the GTX firmware then I get the radio issue which started this post.
However the radido issue did start on the Joying Firmware.... So Cant explain that.
Not on topic.
After blowing up the YD7388 I ordered a TDA7388. This have been fitted and running well!
I then added an extra heatsink to so will perform a bit better which has helped.
I still hope for the GTX to work but waiting on another head unit so I don't have to keep ripping my dash apart.

Touch screen and buttons stopped working help!

My touch screen isn’t working tried everything reset, power unplug, battery unplug. Only works with mouse and dongle,
I want to try to reflash original firmware does anyone have?
This is the same exact model
Double din
Android 8.1
7 inch
Ac8227L
firmware zxdz_2019.18.15
mcu version cvd1810_wj_19.08.02_011
Hi, I think you have wrong PSA / canbus settings in factory menu. Do you have wheel commands and are they working ?

No wheel commands only the mouse works with Donghee plugged into usb. GPS keeps rerouting. No touch or buttons working. It’s the same exact unit in the YouTube video. Tried commenting to user but no reply.
System platform Ac8227L
firmware android 8.1 7 inch double din. zxdz_2019.18.15
mcu version cvd1810_wj_19.08.02_011
zxdz_2019.18.15 is the base for software search here, but I see it uses 8227L chipset, so in fact it can use any 8227L based firmware upgrade.
I have firmwares with android 10 , 8 I don't have. But will search for you on net.
This is your device : https://romprovider.com/stock-firmware-head-unit-zxdz-01/
Firmware and flash tools are inside ! READ CAREFULLY and proceed with update.
Try first update firmware - if it isn't working contact someone who will flash ROM, DO NOT DO IT YOURSELF as you can brick your device if you are not sure what you are doing!
(NOTE: before downloading files in most cases you must ask for permission to download firmware as it is connected to some personal account on Google drive, if not asked anything just proceed with download)
Wish you happy installing and keep me informed if you succeed.
