Hi,
I've been looking for support for a chinese headunit MCX-1705AD without luck. This unit was working fine for 3 weeks, bluetooth, radio, reverse camera was all working fine and now all the apps either open and then close or become unresponsive. I have tried to access infotainment from settings to reset it from there but the screen closes like the other apps. I have also soft reset the device from the front panel which does not do anything. I assume I need a firmware upgrade and I have tried contacting the seller who are useless. I hope someone on here han help me.

I have the same model and problems as you. I already solved the problems and the head unit is working normal now.
1. Turn off the player by turn car key to off position.
2. Frequently touch the screen with 5 fingers at the same time turn on the player by your car key to on position.
3. On your screen conner will show detected and the player go to recovery mode you have to wait for a few minutes until the system reboot.

Hi all,
since I am new in this forum I would appreciate if I am in the wrong section to raise my issues, please let me know and I will accordingly move my post. Thanks.
Following issues I face with my 2 month old UMI Zero.
1. can not make regular phone calls via speaker. my partner can listen, myself cannot hear a word. fact headset icon shows in the very top menue line, speaking via headset works fine but does not make life easy.
serveral factory resets done, updates etc. nothing worked.
2. yesterday, the next issues occured out of nothing. my touch buttons do not operate anymore at all. no function behind except the blue lights. Need to reboot if I would like to switch apps/functions.
Anyone who can help me to solve my problem or experienced same issue(s).
Thank you.

Same issue with buttons with my umi zero
My buttons stopped working as well all at once, considered as contact problem until one day they returned to respond unexpectedly.
After working fine for a while stopped responding once again.
Thinking it's might be software issue, I've installed a new rom material V 3.0 lollipop inspired 4.4 kitkat provided by umi Root joy tool. It didn't help, however, regardless to update the buttons now are lightened but not stable responsive therfore still useless.
For now used this post to enable soft keys: search Google for "enable-soft-keys-navigation-bar-android-phone"
Another free app which I found useful is called My home Button, can be downloaded from play store.
Hopefully a solution will be found soon
The only solution is to dissasemble the smartphone and connect properly the hardware components, you can dissassemble your phone with an hot air gun
Same issue and possible solution
Come on! Are u kidding?
My buttons stopped working yesterday but with a reboot everything was fine again. Until now. No signal from the buttons, light nor fucntion. I'll try flashing it and, if not, i will have to dissasemble and check the hardware.
If this doesn't work I'm thinking about downloading an xposed module that allows you to remap the phisycal buttons. I'll try remapping home, back and settings buttons into the power and volume ones. Let's see if it works.
First of all sorry for my bad english ( I'm french). For the problem with your touch bouton you can also use gravity box ! With this app you can enable the navigation bar and you gonna have touch bouton like the nexus phones. If you don't know how to do that you can ask me question in a next post.
Dear All,
Just want o let you know that after being hesitant for so long, I finally disassembled my Umi Zero and guess what? The back camera connector was not connected, and the touch button + speaker connector at the bottom was also not connected! I just connected them back, put the battery back, and touch buttons + mic were working fine. Tested with voice recorder, playing audio, and also few calls.
Disappointed though by the component assembly....most of the screws were very lose and one even came out without unscrewing. Also, the screws are of different sizes, so please please please take note where each screw goes (What I did is get an A4 paper, made a sketch of he phone outline, and placed the screws on each area where I removed them from).
Note : Most likely you will break the back glass cover so you might as well place an order on Aliexpress before you disassemble it. It is possible to remove it without breaking with lots of extra caution though.
No sound and no soft keys
I had the same problem with my daughters Umi Zero.
I found a work round for the buttons:
-temporarily install an app which emulates the keys so you can navigate. eg Handy Soft Keys from the Playstore
-enable in settings/accessibility
-reboot
-need to be rooted
-install file manager, eg ES file explorer
-in ES tools, activate Root Explorer
-navigate to local/device/system/build.prop
-drop to end, leave a couple of lines space then edit by adding: qemu.hw.mainkeys=0
-save and reboot
You have soft keys
Uninstall emulator app
Backup etc before you start
Haven't fixed the sound yet: nothing from the speaker, phone and headphone jack doesn't work.
Bluetooth does work.
Hi all,
After hooking my phone up to a car stereo, the home and recent key stopped working.
Let me explain:
I just bought a Pioneer avh-x5800dab, with a built in feature that makes it possible to mirror your android device to your head unit. When i unplugged my phone from the head unit, the recent and home button stopped working.
The recent button lights up when i press it, and i can wake and unlock my phone with the home key. Also, both keys works in TWRP. So to me it seems android has unmapped the keys.
Back key works as normal.
I am running KryxOS R1.3
What i have tried so far:
Wipe cache and dalvik.
Uninstalled all apps related to the pioneer head unit.
Dirty flashed the rom.
I would prefer not to clean flash the rom again. Any help and suggestions would be hugely appreciated!
Similar issue
Not sure what causes it but im alao having a similar issue. Home buttong sometimes works on and off but my recent windows key does not register. It recognizes when i tap it but does not work. Also notifications no longer show up at the top.
Having the same issue
Having the same issue with the home and recent buttons, but mine isn't related to the Pioneer software. Notice that I suddenly can't uninstall apps from within the app manager, so I'm wondering if it's related to a security setting. Can't find anything that looks out of place though.

Possible Fix
As I was reviewing some of my settings I got a random notification that I couldn't review a setting because my password had expired. I went into Settings -> Lock Screen and Security and set a new PIN for myself. Home and recent buttons work again and I can delete apps. Weird. Hope it continues to work.

Hi All
I have been reading these forums and generally googling day and night trying to work out what went wrong but haven't been able to solve it so far.
So by means of context I bought an android HU (Brand: Andream EW822P8QH) from aliexpress and was working flawlessly until about two weeks ago.
Details can be found aliexpress dot com /item/Octa-Core-2G-RAM-32G-ROM-Car-DVD-Player-Stereo-Android-7-1-Navigation-BT-For/32834839813.html?spm=a2g0s.9042311.0.0.3da24c4dDGESm4
It's running 7.1.2 and was running the CarWebGuru launcher, when apparently it asked for an update.
Since then, none of the physical buttons work. I've lost all steering wheel controls, so am now just reliant on the touch screen itself, so cannot control volume, etc.
Reading all forums, I understood that under Settings - Car Settings - Steering Control settings should allow you to reconfigure all the buttons once again. Unfortunately when I try to load it, the screen goes white, then goes back to the start of the Setting menu. (Interesting, I had a short cut to Steering Controls on my desktop, but again when I launch it, screen goes black then, back to the desktop
I thought there was something in Settings - Car Settings - Extra Settings, by pressing the code 123456, but once again the screen goes white and seems to go back to the start.
It just seems as though, both these settings areas are corrupted/ gone now.
Can anybody provide me with any clues on what I can get this working again?
Happy to do a factory reset, but nothing seems to happen through the Setting menu.
Was thinking is it even possible to install a new ROM etc. I would say while I've done this on my phone, never on a head unit so welcome any advice on which ROM and some guidance on steps.
Oh I can access the Settings - Dev Options by entering the code 7890 so do let me know if you want me to look at anything there. Interesting one last symptom, my navigation menu bar (by swiping down from top of the screen) no longer works., so definitely seems like something buggy is going on.
Thanks in advance to all who reply.
Hi Everyone!
I've recently installed a Chinese (Funrover) Android HU into my 7th gen Honda Accord. For the first few weeks everything worked fine. Then I tried to install the rearview camera that came with the HU. On the first try before putting the camera to it's final place I tested it and it worked fine. After I put it in it's actual place and tried again, it didn't work. The camera lights up, so power is fine but the HU doesn't switch to the camera's feed.
Next day I had some issues with the HU - the sound just went away. This still happens randomly.
And now recently the HU started turning off randomly, sometimes it doesn't even start up when I start the car. It does work sometimes though. Also it sometimes tries to power on en-route, but usually fails and goes blank again in a few seconds. I noticed that this usually happens when I'm braking and also at the same time the car's original built-in bluetooth unit (which I've never used so I'm not sure how it works) would flash it's leds as if it's getting power from the same source.
Does anyone have any ideas what to check / how to fix this?
Thanks in advance
(let me know if you need any more details)
I have a 12.3" Android head unit. It does not have any physical buttons except a recessed reset button on side. I was playing with developer options and made a stupid error that changed the resolution/rotation of the screen. I am looking to revert back, but screen is black. I can tell the screen is now horizontal as the pop up parking sensor is now on bottom of screen and I was able to press the lower right side of screen to tilt unit up and down. I can start media via the steering wheel buttons and advance music by pressing left of upper middle part of screen. No other screen functions work or come up.
I've updated the firmware from USB, but it did not change the resolution.
Is there a way to boot directly to the developer options from a USB device?
Alternatively, is there a way to reset to factory settings? I've hit the reset button with no luck. Tried to long hold reset as well.
Other option is to reinstall OS from USB, but have no idea how or if possible.
Appreciate any guidance.
Nobody knows what you own out of the hundreds of different devices, architectures and factories that make them.

You really should post the information about your unit:
Currently used MCU
Original firmware version
Current used firmware
Seller of the unit
...but one thing seems to be clear:
You flashed not the right firmware for your special unit.
Get back to the seller and ask him for the correct firmware, flash it and that should fix the issue.
These big screens have their own firmware and you should not flash any firmware if it does not come from your seller.
Apologies. This unit it from China and is a tilt screen designed for Range Rover Sport L494 Series. Has Android OS 10. I don’t know where to find the model #.
I received the firmware file from the seller. , but it appears it did not reinstall the developer tools/ options. They just sent me a different bin file to try.
New bin file reset to factory. Problem resolved. Thanks for replying.
