Ok I gave a new try to Mekede root... so flashtool.exe must be at c:\ on the computer to work but when I put AC8227_android_scatter nothing happened, all is grey, 0kb/s. I tried to connect USB on unit but impossible to recognise (I tried to enable debug USB in dev settings) drive me crazy...

Edit : I totally bricked by flashing MekedeRoot via sd card. I opened unit and saw it's MEDIATEK MT6323LGA 1831AGAH CTG39W03

I'm searching drivers for Windows to connect USB but no chance for now
[Android Head-Units] Doubletop12:
It looks like I may have come to the right place.I have one of these units from Ebay. It reboots every time power (ACC) is applied and again when you start the engine. I went back to the Chinese vendor and they suggested I do a hard reset. Now the left hand side of the touch screen X0-X200 doesn't work. Nor does any of the soft buttons on the left hand side.

I've gone into the factory settings screen and found the touch related functions; Touch Settings, Touch Test, Physical Buttons Study and debug touch.

The Factory Setting App looks similar to this guide on the Joying website dubdubdubdot joyingauto.com/blog/category/head-unit-problems-solved (I cant post links yet) particularly the Physical Buttons Study and step 3 where the X/Y deltas can be set. However, when I select 'config' in the unit I get a config file not found error.

So would it be possible for somebody to post a copy here of that file for me?

Also in the 8227L Factory settings Menu is the "export Config" option. That creates a file metazone.bin on the USB drive. Could I get a copy of that from a working system please? Mine is 1Mb but checking with GHEX it is pretty empty (0x00's). Also any clues on where it is located or how to import the data?

In /storage/emulated/0 is a file calibration.ini it has zero bytes does that have anything to do with it? A copy of that would be appreciated as well please?

Then there is the reboot problem. I have another, different, Android 7 unit in another vehicle it comes on and stays on immediately power is applied.

I have found this file auto_shutdown.sh in the root folder

I hope you can help please? I'm having trouble with the vendor etc to get any resolution or refund

I can't enter a pin with the factory setting or is there another possibility
[Android Head-Units] MusicInMe:
Press and hold the RST-reset button

Keep the RST button depressed and switch on the accessories – ignition key.

Count 10 seconds

Release the RST button

Quickly press and release the RST button two times

On the 3rd press, do not release the button immediately

Count a further 5 seconds

Release the RST button

Wait for the headunit to reboot into android Recovery mode

Once in recovery mode use the RST button to navigate (up or down) or select.

You can try to attach a USB keyboard to the headunit.

Yes I know that. But I don't want to reset the factory settings, I want a hard reset. That means I also want to reset all Android updates. But that doesn't work. If I reset the factory settings then the Android updates still remain on it.

RDS Function ???

Hi, I bought this 2 din radio on Aliexpress.

I have a problem that I am from Europe and the factory FM radio app does not have RDS display station name, artist, song. Is there any application that can run RDS? or is it a hardware problem and cannot be fixed?

Thank you for your advice.
[Android Head-Units] Doubletop12:
I don't think you can. You'd need to buy one with the correct radio chip.

I had one of these it was problemantic from the outset, every time the vehicle was started it rebooted, after the seller advised me to do a hard reset the left hand side if the touch screen never worked. I think the clue is "8227L_demo", and the test apps in the factory settings menu, a wifi MAC of 00:00:00:00 that generate different MAc addresses everytime it connects to a network. It seems to be based on some pre-production build.

After a long battle with Ebay and then Paypal I got a refund and bought another, different, unit from Aliexpress

https://www.aliexpress.com/item/32878594621.html?spm=a2g0s.12269583.0.0.730ab80eaHWBzI

If you select different options, under colour, you'll see one with RDS radio and Android 9. I got one of those and it has none of the problems of the 8227L unit.

So sorry about that...
[Android Head-Units] buckholt:
I got a 8227l android 9. No problems. Only problem i had was when i was saving settings to the mem card. So i stopped messing with settings and deleted the save files to mem card and it all went back to normal. So like they say if it ain't broke dont fix it till it is. ;)

What i have in my camaro.

8227l android Icon Packs

How to install Icons Icons packs and get them work in car launcher like CarWebGuru?
[Android Head-Units] A.S.A.T.:
radio and bluetooth and menu

Good afternoon. I bought a radio HIZPO with 8227L.

Really understand that this is not so. Android 9, the Assembly of the alps-mp-o1.mp5.

The radio is connected properly, the +B and ACC work. The maximum in my firmware is 60 minutes of waiting, after that the radio turns off. And every time I re-configure the radio, sound, equalizer, launcher menu, etc. the Most confusing thing is that the radio stations are reset from the saved, if you pull the key, put the car on the alarm, remove the alarm and insert and turn the key. The settings are almost all saved, the radio does not fall asleep, but the stations are reset! Wrote and attached a video to the seller, he said he sent it to his technical support.

And I noticed that I could hear very quietly from the speakers when talking on the phone via bluetooth. I'm heard well and I'm bad - very quiet (at maximum volume). And initially with this radio I 2 weeks it was set up. I did not want to enter the Google account, I did not want to take a 3G modem, for a long time I could not get odd frequencies.

And when you enter 8888 in the engineered menu, I change the settings there, click save, and after rebooting nothing changes!

Where can we get that firmware on my radio? Or what should I do, demand a refund from the seller? Thanks in advance
[Android Head-Units] buckholt:
I had the same problem. When I saved settings to sd card the stations would always reset. So the way I fixed it was delete the saved file from sd card and reset the settings and after that all was good. Don't save settings to sd card.
[Android Head-Units] A.S.A.T.:
Thanks. Today I will try to do so. What do you think about bluetooth?
[Android Head-Units] buckholt:
It sucks lol
[Android Head-Units] shiner88:
So you bought one of those, and they have rds? could you please ask seller for firmware? it would be nice to have firmware for testing.

if you can't get the fw, could you please copy and upload your radio apk from /system/priv-app? (also canbus.apk would be nice)
[Android Head-Units] Doubletop12:
I'm afraid that If you haven't got the correct chipset no amount of firmware is going to fix it
[Android Head-Units] shiner88:
e

Yeah, i know that, But i'm sure my HU has Rds, just the radio app doesn't show the rds info.

If I use mtk engineering, i can see rds info in radio section.

Also if i tap home while using the radio, a notification with station name is shown.
[Android Head-Units] Doubletop12:
MTK Engineering? Do you mean this screen or the Engineering test debugging screen? If the engineering test debug screen what is the PIN?

I'm not sure I've seen any APK files but when I get a chance I'll have a look. The trouble is, it is installed in a vehicle and I don't get to see it often
[Android Head-Units] shiner88:
Mtk engeeniring mode is an app you can download from from play store or you can find it also under USB settings in the factory settings menu.

For engineering test debugging screen, psw is 26959910 and it's menu for sleep mode option
[Android Head-Units] A.S.A.T.:
Thanks a lot. It turned out, now stations and other settings are not reset!:good:
[Android Head-Units] Doubletop12:
Very useful thanks. The original problem I had was the unit reset every time vehicle was started. My other units don't do that.

I had found this script but its purpose was unclear. Maybe what is hiding behind the engineering test debug screen may be a clue.

After contacting the vendor about the reset issue the vendor suggested a hard reset. After doing that the left hand 200 pixels of the touch screen did not work. I've even reloaded the firmware and it didn't fix it. It took 12 weeks of bickering with Ebay and Paypal to get a refund and I then purchased a different unit that doesn't have any of these problems.

I may get a chance to have a look today.

I can hear the radio stations just fine. Bluetooth and usb connects and shows that music is playing, but no noise comes out, anyone else have this happen?
[Android Head-Units] Gregzilla83:
I've been working with mine for 3 days trying to figure out what does, and doesn't work. For the most part, mine is... functioning. The no mac address is causing some issues, but it'll connect to wireless via DHCP. Bluetooth works fine. USB is a mystery. It connects, but neither my phone (S9) or HU can read each other. Tethering option on HU is greyed out. Both are in dev/debugging mode. If anyone figured out how to tether, let me know!
[Android Head-Units] Doubletop12:
I installed MTK engineering, there doesn't seem much related to touch screens, which is my main interest,however it does tellme I have an MT6625 radio chip. The datasheet says ithas RDS.

https://datasheet4u.com/pdf-down/M/T/6/MT6625L-MediaTek.pdf see page27

My 8227L unit doesn't do RDS either but I have found the system/priv-app folders and have an FMRadio.apk. I've also lookd on my other unit but didn't find a radio.apk. Now I know my way around I'll have another look.

One poblem I know I have is getting files out of the system folders and onto a USB stick. ESFile explorer fails, any clues how to do it without rooting the device?

BTW no CANbus.apk as far as I can see, nor anything to do with the touch screen, which is what I want to fix
[Android Head-Units] shiner88:
maybe look under /system/app for radio.apk

For extracting files, try solid explorer

Anyone find a fix for the mic?

So frustrating. Got everything all hooked up and straightened out except the daggum mic. I just bought this android head unit (the thin 9.1) and the person on the other end of the phone call can't hear me. So I plugged in the external and same. They can barely hear me when I am screaming into it.

I have got to get this fixed.

Anyone found a solution yet or know of any?

Please???
[Android Head-Units] MistStlkr:
I just picked one of these up and have so many questions. I'd start with updating it; mine came with android 8.1 go and the last security patch was Nov 2017. And how do you change the layout of the home screen/launcher? I installed Spotify and would rather have that on the home screen than the local media player, for example. So many new settings to tinker with and not the most comfortable car to be sitting in while I do :P
[Android Head-Units] Maki4u:
I have a similar unit. same problem that it resets everytime i start the car. iturns out +12v constant was going below threshold of the headunit everytime i start. to solve it i put 2x10,000mf caps and a diode at the 12v constant. all is ok now
[Android Head-Units] Eraser5:
Hi,

I have the similar problem, it does not save the settings. Weird problem: there is what save(radio station), some that didn't (brightness, volume)....

Where can I change it to not save to sd card? Is there such a setting?
[Android Head-Units] buckholt:
Not sure. but you do have to save manually. So try deleting the saved files from memory card and then save settings without the card in. on mine I have to save settings from different places.

Now i have a big problem with sound. The music on this radio stopps directly when my tomtom navigation app gives any sound and it dont comeback . Only navigation voice is on. I try a lot of things, in factory mode app there are some settings like mutex etc. nothing helped. It is very strange...if i stream music from my mobile phone to the radio and start navigation app with voice commands the app on my mobile phone stops working to. Press play it works until navigation voice goes on . What is this sh...t ?

Can anybody helpe me with this ?
[Android Head-Units] chicken are smarter then:
I know how

---------- Post added at 11:45 PM ---------- Previous post was at 11:33 PM ----------

on touch settings/config on the left side in factory settings -

you click start then say home then click the home button,

and keep going without hitting config, or close - after you hit the home button go to next one say power then hit power button,

then volume up, then volume up button, volume down then button, then you hit close when you are done it should show a list of all the buttons X and Y then hit ok. you cannot do one at a time. so when you select say home it should light up then go off when you hit the home button, then power it will light up then off when hit button. its all at once to work..
[Android Head-Units] jphilpot7:
For wipe try tapping/holding five fingers on screen while power is first turned on.

For recovery try a terminal app termux, reboot recovery. Also to get wireless adb, try wireless adb reborn. Make sure usb debugging on.
[Android Head-Units] ric69:
Thank you, a long time ago I totally bricked this item by flashing a wrong rom with sdcard, so I bought a new px30 with android 9 and you know what ? it has the same usb issue :silly: impossible to connect my phone, my computer, no dev option in settings, etc... so I don't touch nothing anymore :laugh:
[Android Head-Units] jphilpot7:
if you can get into recovery you can try to reboot in fastboot

reboot recovery from terminal or reboot bootloader.

if you just want root access, try using termux and do su @#zxcvbnmasdfghjklqwertyuiop1234567890,.

8227L_demo:/ $ su @#zxcvbnmasdfghjklqwertyuiop1234567890,.

8227L_demo:/ #

If you try to supersu it might softbrick and you would need firmware.

Just make sure you have firmware.

reverse radar not working on 8227L

Hello

4 sensors of reversing radar for French car model Peugeot Partner Tepee, are connected originally to radio but after replacing with new 8227L Android, there is no beep sound from speakers.

Beep works only with old Radio.

How can 8227L android make these sensors readable?
[Android Head-Units] SharkysRacing:
Go into factory ( 8888) go to Amplifier settings and turn it down about half way.
[Android Head-Units] SharkysRacing:
I have 3 of these 8227L units . One is a 10.2", other 2 are 9". All are 8.1 Go. 10.2" so far all is good. Both 9 " have issues. 1 of them no sound. Other one has high pitch consistent squeal in FM radio. Sometimes louder then others. Both if you plug in SDcard it mounts, unmounts in 5sec cycles. Kingoroot opens and crashes.

One i decided to explore. After dismantling found SEVERAL internal components had been removed and ribbon sockets unused.
[Android Head-Units] MistStlkr:
Hah. I actually figured it out last night. I don't know why it took so long to find that, obvious in hindsight. Thanks for the reply
[Android Head-Units] Bakelmania:
Exact same problems with my Hizpo 8227L unit. I used 9191 instead of 8888. This forced factory reset, which enabled me to then enter settings via 8888 and the settings are now saved on reboot. Everything else stayed as originally set, except FM radio tuning range changed to 90 - 97MHz only! Reset radio region to Europe, but tuning range is unchanged. This radio is a pain in the neck and it's clearly due to the vendor deliberately setting the unit to restrict functions/access. The seller just wants to sell add-ons, rather than fix it!

hey guys, im going to try to upload a video to show the head unit, its a google link, hope it works

https://photos.google.com/share/AF1...?key=N1hQbXZiRzZZcFBWOXJKV2RtWXRtSnVXOTl0Wk5R

Ive tried relearning keys, factory reset, physical reset like 100 times with the paperclip push button, nothing works, any help guys would be greatly appreciated, possibly even a root solution if thats what it takes
[Android Head-Units] SharkysRacing:
Bad firmware. Or maybe the ribbon inside came loose. But if it was only after reset. Then yea. Your firmware for the buttons are loaded After Firmware.

I have found that some of these companies has 1 guy load the boards with Firmware. Then pass them down the assembly line. Next person put the wrong buttons with the wrong buttons. By the time its gets down to testing. The last guy loads software for incorrect components. Then when factory reset. Only the stuff from the original firmware guys stuff is there.

I did find a site that seems to have ALL the drivers for these things. But i have not been able to confirm any. Bought a external HDD which ofcourse is to big until i can partition it. ( to lazy ) waiting for my 2 new flash drives thats been out for delivery for 4 days now. Lol

Found something pretty frigging interesting. I am still working on this. BUT i have been able to correct a few of my issues. Check out the following pics. This would explain why most of my features dont work. Between not allowing access or " Dummy Icons " amazing just amazing. These Guys/companies make great looking products, with great future possibilities, but yet block the options to use them, and instead enable the software/hardware to fall apart once the internal timer hits a preset hours of usage. Shame and damn shame. My unit is at 10hrs 42 min. Total runtime. Which i found on here at 10Hrs was scheduled to start acting up which is about right. And scheduled for total crash at 14hr runtime. Im gonna poke around alittle more when i get back into town.
[Android Head-Units] SharkysRacing:
I ALSO think i found a better way to be able to Root the device. Again will know more once i get home. Looks like a simple " Yes" or " No" would allow Root
