Hi! I recently received a firmware from xtrons for my xtrons PSA unit. I will share it here and maybe it wil be useful for someone. I have still not managed to update the firmware as the update doesnt start when I plug in the usb stick (I have now tried four different USB sticks, formatted to FAT32). I am asked if I want to use the device as portable storage or internal memory or something like that. It doesnt matter what option I choose, nothing happens. Any advice?

Soon I will give up my attempts with this unit. Luckily I received a full refund and got to keep the unit.

”Here is the latest firmware for this model,please factory reset the unit by accessing settings -- Car infotainment -- about device -- click the gear icon in the upper right corner and enter 8888 or 8878 and click ok -- Erase All Content ,then refer to the instructions below to update it.

Unfortunately, this is not my firmware. If you know how to find out the activation code from the firmware? I'll try to do it.
[Android Head-Units] Anton TNT:
Hm, watch out users, issue with that new firmware, it is not for everyone or for every unit,

This update is only for units produced and sold after year 2022 and with firmware marks FFKJ, XRCH, JC.xxxxx..xxxx.xxx. Other units similar and with 8227L chipsets will be experiencing ACTIVATION DOES NOT MATCH error.
[Android Head-Units] Skinny_Chef:
I was having the Bluetooth issue, and flashed a new rom without making a backup first. The rom works fine, but the physical buttons no longer work correctly. Can anyone offer help?
[Android Head-Units] Anton TNT:
Ask your seller to give you files for import for buttons/knobs, or if not given , use mine, also given by seller, but note that this are not specific for your unit and might not work or arrangment of knobs will be different , like NAVI will be button of DVD etc.

IMPORT FILES for buttons knobs

- procedure for install is to go into factory settings, then BUTTON menu and then hit IMPORT button and choose this file as rar or unzip them first and choose one at a time and install, unit will assign knobs and will wait for restart to take effect.
[Android Head-Units] Skinny_Chef:
Thanks! The seller said they no longer offer support for my purchase, but they’d be happy to sell me a new unit.

I’ll give the import a shot. I really appreciate the help!

Opracowałem prosty sposób na migającą ikonę bluetooth

1 Trzeba wejść w aplikacje adninistracyje

2 Odznaczyć opcję Znajdż moje urządzenie i najlepiej wszystkie pozostałe

3 Przejść do zakładki Wszystkie aplikacje i znaleść Usługi Google Play

4 Wyczyścić wszystkie dane

5 Kliknąć 3 kropki w prawym górnym rogu i przywrócić aplikację do ustawień fabrycznych.

6 Uruchomić ponownie radio kodem 1414

7 Cieszyć się działającym bluetooth.

Warunek

NIE WRACAMY DO APLIKACJi ADMINISTRACYJNYCH I NIC NIE ZAZNACZAMY BO W PRZYPADKU AKTUALIZACJI USŁUG GOOGLE PLAY STRACIMY MOŻLIWOŚĆ ODINSTALOWANIA AKTUALIZACJI.

Zalety

Pozostaje oryginalny system dostarczony przez producenta brak problemów z licencjami i nie działającymi przyciskami lub pokrętłami Można aktualizować aplikacje i sam Sklep Play

Wada

Po aktualizacji Usług Google Play trzeba powtórzyć punkty od 3 do 6

Instrukcję wstawiam w języku polskim PL

Google translated

I've worked out a simple way to get the bluetooth icon blinking

1 You need to enter administration applications

2 Uncheck Find my device and preferably all others

3 Go to the All Apps tab and find Google Play Services

4 Clear all data

5 Click on the 3 dots in the upper right corner and restore the application to factory settings.

6 Restart the radio with code 1414

7 Enjoy working bluetooth.

Condition

WE DO NOT RETURN TO THE ADMINISTRATIVE APPLICATIONS AND WE DO NOT TICK ANYTHING BECAUSE IN CASE OF UPDATE GOOGLE PLAY SERVICES, WE WILL LOSE THE POSSIBILITY TO UNINSTALL THE UPDATE.

Advantages

The original system provided by the manufacturer remains, no problems with licenses and non-working buttons or knobs Apps and the Play Store itself can be updated

Defect

After updating Google Play Services, you need to repeat steps 3 to 6
[Android Head-Units] dedalos91:
@szymon7805 With new firmware (posted here) you can update Google Play services normally without losing the Bluetooth icon and functionality

Note

With new firmware, I noticed bluetooth might break if you install apps that try to control it, be able to turn it off/on (like bluetooth file transfer app for example). Then you have to reset WiFi / Bluetooth from the system settings and functionality will be restored

Hello everyone, I have this car radio with the following firmware and touchscreen buttons, I have the same problem with bluetooth and system jamming that makes it unusable, I tried to put the files on page 43, but the play service won't install it for me. To solve there is definitely a firmware compatible with my system
[Android Head-Units] rohan_agashe:
Better to ask the dealer for the update files first.

If you don't get update from the dealer, try to do a hard reset first and see if that solves the firmware looks from 2019. If that didn't fix try to disable google services and see if that helps.

If nothings first try to take a backup of the existing from with SP Flash tool and then try to flash some firmware from here.

[Android Head-Units] Anton TNT:
Update to latest firmware for unit (2022 - find on earlier pages of this thread or use 2023 - the recent one published a few pages ago) , then disable Chinese playstore , then download on a PC Google playstore apk and install it on unit. It will work!
[Android Head-Units] cr4ck3dn:
How you installed this? There are a lot of files and folders not two .bin. ty
[Android Head-Units] Baban2013:
*1-Remove the suffix () and find an empty USB drive.

*2-Download the file to the computer, unzip it, and then place it in the root directory of the empty USB drive.

*3- Insert the USB drive and power it on again.

*4-The machine will automatically upgrade, and the time will be relatively long.

*5-Do not power off until the upgrade is completed.
[Android Head-Units] annejo:
My unit restarts randomly without any apparent reasons, so I search for a new firmware here and found the one post by our senior member dedalos91 at the above post and I would like to take this chance to thank him.

Have been using it for a few days without any problems, no random restarts, FM Radio, Music player, GPS, bluetooth all works flawlessly. I don't use SWC so I don't know about that. No activation code ask.

Here are some shots of the unit, it is marketed as Mirai MR-7227 in my country but it is the same Chinese head unit as Xonrich or maybe some other MCU brands.

Note: Install must be ENABLE, protection must be DISABLE before flashing.
[Android Head-Units] dedalos91:
what exactly do these settings do? for example what is this MCU type 1 or 2 or 3 etc? can you explain these options? have the options you suggest been tried by you?

for bluetooth I found this,

Difference between ACL and SCO Link in Bluetooth

Difference between ACL and SCO Link in Bluetooth - Two types of data links are defined by Bluetooth link layers−Synchronous Connection Oriented (SCO) LinkAsynchronous Connection-Less (ACL) LinkSCO is a symmetric, point-to-point link between the master device and the slave device connected via...

www.tutorialspoint.com

what is your opinion?
[Android Head-Units] Anton TNT:
MCU types : setting 1-7 - like , you tell your PC with how much freq and clock it will work , on 50% 80% or 100 %

- consider it like BIOS setting for processor and memory , but , setting 5-7 most common will fail with some units below 2GB of active memory - but gennerally improves unit response and with no lagging

As far as I understand it , Bluetooth version or BTOOTH VER option gives unit communication with bluetooth device , if your mobile device is not responding with connection to unit at lower values like setting 2 or 3 increasing it to value 4 or 5 gives means that you use software available for communication for new Bluetooth softwares in mobile phones. It does nothing more than synchronizes softwares between mobiles and head units in order to connect each other.

Option INSTALL grants user (not superuser or admin) to install all options settings and perform as superuser/admin and while PROTECTION option is OFF, units has full access to flash re-update etc.

AUTOLINK option must be enabled always , it is by default, autolink connects all third party softwares like ZLINK TLINK and other mobile phone softwares together in order to work with each other
[Android Head-Units] Anton TNT:
Works best because it is most common update (new update from 2023 for older units) for devices that are MTK based (MEDIATEK) and has older chipsets 8227L.

I have seen also that in some way corrects problems with Google playstore or unit crashing beacause of Chinese playstores (moded Google playstore) installed
[Android Head-Units] dedalos91:
thanks

so for mcu 7 means 100%? or 1 means 100%?

and what about bluetooth?

- Bluetooth SYNCH option must be ON or value SYNCH , not ASYNCH

what value is better? based on the link I give below?

https://www.tutorialspoint.com/difference-between-acl-and-sco-link-in-bluetooth
[Android Head-Units] Anton TNT:
SYNCH = SYNCHRONIZE software with mobile phone or other bluetooth device , master connection controling over other devices

ASYNCH = mobile phone or other device or software is controling bluetooth connection

MCU set - 0-1 - 90%-100% all cores (quad or octa cores)

2-4 - 70%-90% all cores

5-7 - haven't tried but heard that all cores works at 50% to prevent overheating
[Android Head-Units] Redguy37:
Hi so much thanks for firmware, this is by far the best, and i tested it all. some have bluetooth issue's or gps dont work. But is there any change you have a activation code for the android auto.

Back Camera image is only shown before Android is launched.

I'm new to this forum, so sorry if my question is offtopic, but I see experts use this thread.

I Recently bought a used car with an Alps FF5000 / 8227L Android Head Unit installed in it.

At that time the reverse camera worked well.

But I had to adjust some parameters because the previuos owner speaks different language and I may have accidentally set some unwanted things, too.

The symptom:

If the transmission is in reverse when the ignition switch is turning on, the head unit will immediately display the car's cameras. This state can remain indefinitely until the gear selector is moved out of reverse mode. Meanwhile, the Android system starts up in the background, and after that the camera image does not come back when I switch reverse again. Instead, it just becomes a black screen without any messages nor any possible interaction.

So, the car's cameras are only visible when Android is not running. When Android is on, the unit recognizes the reverse state, mutes the radio and blanks the display, but shows only a blank ow-light screen.

If I want to see the back camera image when Android is running, I have to enter code 1414 to reboot the unit.

Other functions and apps I use work well.

The car is a 2013 made J10 version of European Nissan Qashqai with 4 cameras.

The composite video sign of the cameras is provided by Nissan's Around View Monitor Control Unit - works well. It recognizes when the transmission in reverse and then powers up cameras, make a composite image of them (big back picture with auxiliary lines and a smaller bird eye view image beside). It's wire of composite video is connected to yellow RCA of HU.

The raw image is shown by hardwer well, but when Android is on, it overrides it. I tried a lots of secret codes found in the forum, but never saw any settings for parameters of yellow RCA input video format (set it CVBS, fps, 525 / 625 lines...)

What do you suggest, which item's setting from which menu to try for to which value?

If I made a factory reset would I lost every apps - including Radio, DSP,...?

By the way, which menu setting is for factory reset?

HMI: JC.D.Q.F.2.01.2020.11.18.14.30

MCU: TS907.190518(H)

MEDIA: HC_v2.0.0_200416_0930(v1.84)

Thanks in advance for your help
[Android Head-Units] Anton TNT:
Hi, if your code for entering factory mode is 8888 go to video setting and try to fix issues there along with TCON settings - enable it by checking box next to TCON settings
[Android Head-Units] YİGİT1940:
I want time and date on the home screen. Is there an apk for this?
[Android Head-Units] fifi_57:
Hi Anton,

thanks for response.

Among in 8888 settings there is a DISPLAY menu which contains TCON settings. But it's irrelevant whether TCON is ON or OFF.

What about some settings of 8888/OTHERS , maybe something there? (pictures attached.)

There is also a 8888/ATV menu with several PAL, SECAM, NTSC and RES option, without any details. I tried change it from one to other without luck.

I saw a youtube when somebody changed camera settings CVBS and AHD with different Hz.

Is not here somewhere any similar options?
[Android Head-Units] Anton TNT:
OPTIONS to change :

CAM TYPE = 1 is default or select 2 if not working

CAMERA DETECT = 1 (ON , 0 is OFF)

PROTECTION = OFF

INSTALL = ENABLE

Set your camera app again , install it and tweak

then set: LAST MEMORY = ENABLE / REMEMBER -> after unit is restarted and camera is working again

If not working again check camera wires or contact between cabble and head unit. Also try with new app that supports back camera and 360 camera
[Android Head-Units] Anton TNT:
No you cant change that, this is standard interface of device and interfaces can only be changed as themes.
[Android Head-Units] YİGİT1940:
Can I find the apk of that theme?
[Android Head-Units] fifi_57:
Thank you, Anton.

I have adapted the settings to your suggestion.

But I'm afraid I don't know which camera app should I install and tweak.

What app is that exactly? User installable or a factory installed one? And from which source can it be obtained for installation, not Gogle play, is it ?

The head unit came with the car without any manual, nor software.

The camera wires or contact between cable and head unit must be good, since the back image is shown well - before Android is launched, or after a code 1414 reboot. Some software settings in the system is prevent to show the image.

What do you think about an wild idea: to unplug the reversing camera cable from the yellow RCA input of the HU and connect it to the (currently unused) Video IN cable of the HU instead.

When I switch transmission to reverse, the car's Around View Monitor Unit provides the back image immediatelly, as I described it earlier, so I just should touch the AV_IN on home screen to see the video input. Would it be work? Will the composite video sign compatible to the expected Video IN sign?

Or make factory reset? But I'm afraid other functions go well now, will be wrong, producing more questions...

Sorry for the stubborn problem.
[Android Head-Units] Anton TNT:
You can try it your way with changing video input, rca connection might be faulty or restricted.

About video apps, you can use current default one or install other third party apps from playstore or if you have contact with seller ask him to give you app for reverse camera. He must have those kind of things.

If not you can try to install these and try with this ...

Good morning! I have a multimedia with these characteristics, I bought it a few days ago and it is listed as Android 10. I would like to know if this is really what you mentioned, that this 10 is a fake Android and that it would actually be Android 8.1. Sorry for the question: is there any way to prove what you said? If you are right, I will create a dispute with the seller who provided it to me. Have I been scammed?

[Android Head-Units] Anton TNT:
Roll back on some earlier pages of this thread and find firmware update , year 2021 or 2023 , download & unzip then transfer on USB drive two files, and update when units starts (usb drive with files must be on port when unit turns on - whit car engine on). Leave installation to end automatically and that's it.

Try installing again a default app/program called gps test / signal (I don't remember the name of this app). Procedure -> go to apps section of car settings, find that app and delete cache memory and data, then disable this app and then re-enable and restart unit.

Try that first.
