Hello,
I recently purchased this unit:

The install was a little difficult but went okay. For some reason when I try to login to login to google playstore it automatically closes. I have tried allowing app permissions and clearing storage and cache. It says it is running Android 10 API 29 (qp1a.190711.l020). It has carlink installed but does not seem to recognize my phone. I have managed to get the Bluetooth working, but I guess I should have done more research and gotten a unit that other people have. Do I risk bricking the device if I try to flash another version of android onto it? I like the DSP and some of the features but I can't even log in to google. Also could someone tell me if this is MTCD or the other? The company is responding to my questions so far but it was really late in China when I told them I can't log in to google, so hopefully they message me with a fix tomorrow. There seems to be 4 instances of an app called "Launcher 3" and an app called "App store" that says it could ruin my device if I try to uninstall so I just disabled it. This thing seemed to have all the features on paper, 8 cores, 128gb ram, 4gb rom, DSP, dash cam, rear view cam, optical audio out, 4g antenna, external sim card, gps antenna, 5 g capability... you name it. They "accidentally" sent me the 64 gb version instead of 128gb but they sent me a free dash cam and tpms to make up for the mistake (which they denied at first). If anyone knows why google would be doing this and a fix please let me know. Big let down for 450 bucks.

    Please post a picture of the system about screen for your unit, that would help determine if it is MTCD/E. You should be able to find such a screen in the settings.

    You're pretty lucky that they're responding to your inquiries. There is a chance that your head unit is not running Android 10 and may be fake in many regards (e.g. running much earlier version and "claiming" to be Android 10)).

    Thank you for the quick response. Yeah, at least they are responding. If you click the add it looks so legit with the 8 core 64 gb 4 gb ram. But my home screen looks nothing like what they advertise.View attachment Home screen.webp

    Please scroll the view up on the about screen and take another picture. It is hard to see with what looks like plastic film on the screen. Would like to see the MCU version and perhaps additional information. Thank you for posting the first picture.

    Oh and my pleasure to try to help you. We need to determine for sure what the head unit is and if it's MTCD/E I along with others here in the forums would be glad to try to answer your questions and help you resolve the issues you're having.

    The only units I could find that use that particular CPU (UIS7862) are Joying branded head units. Their units are not MTCD/E. That being said, this thread probably should be moved to Android Head Units as the discussion in that forum are for non MTCx head units.

    I will offer you this suggestion regarding the Google login issue, try opening the YouTube app or Google search app and try logging in from one of those. Alternatively locate the Accounts section in the settings and see if you can login to Google from there. That may help with the Google Play launching issue. If you can get GP to launch then you will be able to get Play Services updated and other applicable updates to make the Google apps/ecosystem work.

    Once you get Google Play working, I would suggest installing an app like CPU-Z to see what your system consists of.

    One more thing, welcome to the XDA community.

    For sure, I have heard the Joying are decent. I haven't been able to get it to interface with my phone other than viewing it as files. I cant do the mirror screen split screen that is advertised in the AliExpress ad. I tried to download Zlink apk and install it (disabled third party app restriction) and it said not installed. Maybe I need an older version than 4.0.6? Unfortunately none of your tips worked, even the google one, but thank you so much for taking the time to assist me. Hopefully the seller has a fix for this, as I am not great with android.

    Sorry that my suggestions did not work for you. I have asked the forum moderators to move this thread to the Android Head units forum where maybe someone in that forum maybe has experience with the same or similar head units as yours. Suggest searching the forums here as I'm confident that somebody has solved the Google login problems you are experiencing.

    Your head unit should just work out of the box. I would not recommend updating firmware or such major changes before getting your unit working at a minimum as you expect. Thing with that is how will you know if additional problems that you might encounter are from the update vs what you have now?

    By selecting one of the variants of launcher as the default launcher app you should be able to get the user interface to look as shown on the ad where you bought the unit. Since these devices are sold under many brand names, they often include many different launchers which is what provides the user experience seen when the system boots up.

    You should find a default apps selection in the settings where you can pick the default launcher.

    One more suggestion that might get it where you can login to Google would be to locate the factory reset option in the settings. Since you couldn't install any new apps on it anyway, not much to lose customization wise.

    I believe there is a system patch for the FYT IS7862 units. My IDoing came working so I assume it was already patched, but if you head to the Joying thread you'll see posts about a system patch. Not sure that patch will work for your unit, I think that's what you need.

    Actually, they are being pretty helpful. They just sent me an update I have yet to install (kind of afraid as it is working now and I realized I don't really need google integration. Here is a screenshot. Good to know it is a FYT IS7862 unit.

    Just for fun I went to the download page and did a screenshot of the page. I then ran the screenshot through the Google translate app. With the transition set to go from Chinese to English, the download link says "overseas system. rar".

    You could possibly run the PNG file that you attached to your post thru Google translate and maybe figure out the filenames. The picture is not clear enough to do the same as the picture resolution is pretty bad. Was hoping maybe the download filename would offer some clues about what the rar file contains.

    Maybe you could request from whoever sent you the link, an English version of the download if available. Granted they say something about English text showing up in green after the flash. I could totally understand your apprehension since you cannot read the filenames.

    I could unrar the file and try getting filename translations, might be helpful.

    Man, I really appreciate you looking into that for me. I went ahead and bit the bullet and did it and it booted up with a different theme and reset to factory settings. Seems to be dropping my home wifi connection now. I havent tried putting a sim card in the unit yet, as I only have a micro sim from my tablet. I asked her several times what we are upgrading and she said it's not the android version, but a fix to make google login work. So, I went to login to google and instead of getting hung up and crashing after the "checking info..." screen it actually had a box to type my gmail address and let me type it and press login. Then it said "Cannot contact google servers, try again later.
    This 1.4 GB file seems large for a small fix. There were like three ZIP files in the rar. Also, when I look at what is using memory on the unit there are like 10 apps I didn't open in the background. Makes me feel like the mfg. has some spyware or malware on the unit. Isn't it commonplace to completely wipe one of these units clean and install a different version of android? Why couldn't I just install android 11? Is it becasue I wont be able to find the apks for unique apps and functionality on there?

    They usually (never) provide system patches that fix one specific thing. By providing the whole system update it still makes it impossible to know exactly what's being installed.

    Unfortunately it's not so simple to go from one version of Android to another as they intentionally make it difficult to do. It kind of puts a lifespan on these units. There's always gonna be something broken or something that will eventually break rendering the unit useless or just be a flaw that you end up accepting. Plus by limiting the Android version its planned obsolescence as updates won't always be available forever.

    Maybe and it's a big maybe you can find an alternative ROM for your particular system right here on XDA. Those are becoming more and more rare because of numerous factors however.

    I wouldn't recommend logging into the head unit with a Google account that has a payment method associated with it. Maybe create a whole new Google account just in case? Also you could try going somewhere that you can get free public WiFi (e.g WalMart, McDonald's, etc). All that would do is confirm it works, for what it's worth.

    Regarding the wifi connectivity issue, was it able to connect to the same wifi before applying that provided update? Is the wifi signal strength good? It's likely connecting to the wifi but not getting an IP address and other connection parameters and disconnecting on failure. There is an advanced workaround that involves manually setting the network connection parameters (e.g IP address, etc) but you'd need to be comfortable with doing that sort of thing. Let me know if interested.

    Despite the update essentially doing a factory reset as part of the firmware installation, I suggest manually doing a factory reset. Maybe even do the reset a couple times just to be sure. Truth is that the device should just work out of the box without the extra contortions.
