All,

Watch out! I'm one of the victims fall into buying a 7" 8227L unit with fake info in System Info.

System Info shows 1) Android 9.1; 2) 2GB RAM & 3) A7 with 1.3GHz CPU. However, CPU-Z shows OS is Android 8.1Go. RAM is only 1GB & CPU is running at 1.12GHz.

Firmware is YT9213B_00008_V003_20191028 (28 Oct 2019). It means the scam is relatively new.

Be very careful before you place an order!

Ich werde meins zurück geben.
Radio Empfang geht, aber es ist ständig am suchen und abspeichern.
Musik.... Spielt irgendwas ab, was es gar nicht soll.
Und und und..... Nur Probleme mit dem Teil.

I'm confused on how to select the correct ROM for this head unit. Can someone shine some light on this?

Sys Info says YT9213B_00008_V003_20191028, but CPU-Z reported "YT9218_00008_V003" & API Level is only 23 which means it's a Android 6 OS!

Can I use a YT9218 firmware to flash it...!?

Ja, die kannst du nehmen, wenn du Glück hast dein Laptop anzuschließen.
Ich habe es versucht, jedoch erkennt mein Laptop das Radio nicht.
Hab mich belesen hier und alles mögliche ausprobiert.

Hier ist ein thread wo alles beschrieben ist


https://forum.xda-developers.com/an...-firmware-chinese-7-head-unit-ac8227-t3931863

Hi, I don't read German, but Google does! Anyway, have you tried the "2 pins short" approach reported in the [ROM Firmware for Chinese 7" Head Unit] thread?

For me, current firmware is quite new (28 Oct 2019) & more importantly it is stable. I've managed to change start up boot logo without issue of infinite boot loop reported by others on earlier firmware.

Only missing feature I need is the speaker balance & fader function. It maybe too risky at this time to mess with firmware just to have this feature...!

Nein, hab ich probiert. Meins ist noch eingebaut.
Bau ich erst am Wochenende raus.

Also Balance Einstellung müsstest du bei den Settings haben. Bei meinem ist das vorhanden.

Ansonsten mal bei factory Settings schauen.
Pin ist 8888

Aus dem benannten thread kannst du die mcu update runterladen, auf einen USB Stick machen und aufspielen.
Die Firmware kannst du auch so machen, aber du hast ja schon eine neuere als die im thread.

My unit does not have Balance & Fader in setting. Strange!

I've managed to enter Factory Setting (see attached picture), but I cannot find an option to turn on Balance & Fader feature. Any idea?

Hi rabiat18,

Thanks for the pictures!

For an unknown reason, my unit does not have the balance&fader button in audio setting!
I'm puzzled since I have the unit installed 2 weeks ago!

Knowing the 2GB RAM is fake, I have a question on flashing ROM. Should I use a 1GB RAM version of firmware to flash!?

can you help me upgrade the android head unit from 8.1 t 9.0 attaching the screenshot of build info . I`m confused which firmware to use.
Screenshot link:
https://drive.google.com/file/d/0B-DeZ2cJS-h6UFVKSkswdExXX2NMNnc2akoydS1jcVQxd1hN/view

What you see 8.1, 9.1 & 8.1Go are all fake information! No point to upgrade...!

If you use CPU-Z to check, you'll see API Level is 23 which is telling us that our units are actually running Android 6 (Marshmallow).

okay since i`m facing issues in radio, the reception is sometimes lost and after few seconds its gained again so thought of updating the device also checked wether the radio antenna was loose or not but it had fit perfectly in the slot. Also wanted to know is there any way to set volume after startup . By default on startup the volume is set at 10.

i spent 120 on an android stereo on ebay and had the same issue. ended up being fake android 8.1 and being 1gb of ram but saying 2gb of ram and android 9. i filed a claim with ebay, the seller offered 50% off. i countered with 75% off and they took it. i ended up paying 30ish dollars for the stereo. to be honest, it works perfectly (save for the radio, but i don't use the radio so i don't care. i just use the thing as a carplay window). file a case with aliexpress, chances are they'll refund you some or all of your money, these things cost jack **** to make..

I did receive compensation from seller too. Similarly, I'm keeping the cheap unit primary for wireless CarPlay purpose. It's been pretty stable so far.

    An alle FAKE-BESITZER!!!!

    ladet euch diese Firmware herunter.
    Bei mir funktioniert sie.

    Es ist die Firmware von Pumpkin mit Android 9.
    Multi Windows Mode ist auch mit dabei.

    Auf sdcard extrahieren, einstecken und Radio starten.
    Firmware startet automatisch.

    It worked like a charm... So easy :good:
    Downloaded, createfolder in usbdisk - reset button and just had to wait.

    I didn't deleted the file "preloader_8227L_demo.bin" any problem with that?!?

    The interface looks good is it possible to change the date and time format?!

    In this site u shared (https://4pda.ru/forum/index.php?showtopic=936535&view=findpost&p=92095779) I saw FM radio APK with themes and stations name but the download link it's broken :eek:

    Which GPS should install to work in offline mode... sygic? Handed? Or stay with Google maps and download offline maps?

    Great you did it!!! Offline GPS Sygic is ok but also Here we go is good and FREE. For sygic you should pay.
