Hello guys!
I have Xtrons D714A with original ROM (4.4.4) and recently I installed Car Launcher on it. The next day when I powered up the unit again it showed a screen that I have to choose the default launcher for the unit. Anyway the problem is that the touch screen stopped working and I cannot choose anything. The strange thing is that the notification bar is working, I can even dial up the settings bar and enter in the menus, but once I enter there the touch screen does not work as well (it only works in the notification bar).
I tried to reset it trough the reset button but it only resets the settings, I need hard resset to erase Car Launcher. I also tried to turn on the unit while holding all kind of combinations of the hardware buttons but nothing happened - I think that the "power" button is not actually power button because when the unit was working the only thing it did is to get the unit in sleeping mode when I hold it.
I contacted Xtrons but no answer from them by now. Also I saw that I am not the first one with this problem :

http://forum.xtrons.co.uk/forum_posts.asp?TID=143637&title=d714a-touchscreen-not-responding
Can someone help with this issue?
Thanks in advance!
Is there some script that I can upload on SD card and do a hard reset if I power up the unit with it? Or upload new ROM and install it from SD card by the same method, and if yes, can someone provide me ROM file?
@strballer try emailing Xtrons at: [email protected]. They usually reply within a day or two. They should send you a link with a firmware download as they did for my D717AL.
Thanks for your answer! I already contacted them and they suggested to turn off the main power for 15 minutes but as expected this done nothing but just reset the settings of the unit, not hard reset. Anyway I just managed to fix the problem. I connected USB keyboard and I was able then to dial the default home launcher. After that the touch screen was working again. Very strange bug...

They told me there´s no firmware available. Did you mange to have Android 6 on your xtrons D717AL? Since it is sold with this now as far as I read somewhere. I stuck on 5.0
I bought a Lemfo lem7 smartwatch yday through aliexpress. During settings I switched the screen lock option and now cant unlock the screen doing whatsoever. I have rebooted by pressing the power button to no avail. Can anyone help? How can i do a factory reset as this watch has a single button?
About the same question
I got mine ordered at Banggood 2 days ago, and tested it's feature's without SIM card so far. Last test was company email configuration using exchange account setup. All worked out fine except the required pin-code unlock to start Andoid (after reboot watch).
After a while i got annoid to use the pincode input, and liked to get rid of the exchange account so i deleted this account in my LEM7.
But next reboot, i still got this pin code input screen but without onscreen keyboard !!
So the same question as topic starter, how to restore - do a factory reset with only one physical button ?
Or using the supplied smartwatch-dock with USB connection at Windows computer.
What procedure ? Software ? How to obtain factory ROM not having any backup ?
Next i will send Banggood.com service request.
thanks for any support , Hans
Yeah. Anybody knows please respind. How to do a factory reset with one physical button?
Have anybody found the solution to rsset LENFO LEM7 physically??
Go to proboards, maybe they can help http://roundandroidwatches.proboards.com/thread/2252/lemfo-lem7-discussion-thread
Hello,
I guess you have to hold the power button in booting process. So long pressing power button for 10 second to reset watch and then during booting again long pressing power button. I guess then you will see new boot menu where will be HARD RESET option. This process is more or less same for all Android devices
Good luck,
Marek
Make a reset using your Google account!

And how would this fix a device what does not start Andriod before entering 4 numbers at the same device what does not shows a keyboard to enter these numbers ?
No, neither a solution.
Meanwhile i've returned my LEM7 to supplier Banggood, got my money including shipping costs refund. And have bought a THOR4 smartwatch instead. But i would not try to enable the security setting to input a pincode anymore neither at my current THOR4 device.
Another thing, experience of the passed weeks having a 'cheap' smartwatch with all it's features including 4G , most apps running on a small and round display and very tiny onscreen keyboard are hard to use. Or not even to install when required to tap at YES / NO the yes or no is not visible on the screen neither full round or squared display setting.
Using a 2 (micro) sim card of my provider, can only use one device (watch or smartphone) at the same time. Have to set one in airplane mode to use the other as a phone .
And have you ever entered a password at onscreen keyboard on 1.34" round display ? not easy done for shure i can say !
Do consider the smartwath as a nice gadget, practically spoken prefer to use smartphone or larger display sizes .
Best regards, Hans

Finally succeeded. Couldn't do it from my pc but the Lemfo still had bluetooth on. I paired it with my smartphone, connected and I was able to erase all. Now the tedious reinstalling except the suspect app, whuich had been ok until the latest update. You had the right solution, thanks
I have LEM11 and my my kids forgot smart watch’s passcode and currentry I can’t login.How can I do factory hard reset?
Hi all
I bought a second hand car stereo 8.1 reference 8227l Chinese without name ... see pics
I have several problems : impossible to find how to go into recovery and therefore impossible to root for now ... (I tested all possibilities: reset / power and all keys)
But more serious: impossible to have access to settings / accessibilities necessary for google maps which bug in navigation, or install a program like "velociraptor" to have the speed in real time
Cannot find out how to do a hard reset too : rolleyes: there is a reset / settings function but it does not do anything ... reboot everything stays in place
Thank you for help and good day
Usually reboot and volume +
Thanks for help but not possible with vol+. I'm not sure buttons are enabled during boot they're lightning only after android is running.
Android Head Unit 8227
Good day to everyone, ive also got a head unit 8227L from ebay, its a 7" android 8 head unit, none if the physical buttons do anything, they died after i changed the boot logo, i have tried putting it back to the original one but no help, on top of that, the touch screen dosent work in the cold, and here in the great white north, its 30 degrees below freezing for months, Ive tried everything to get them working again but no luck. I have to use a USB mouse to even do simple things like change volume, so needless to say, its a useless radio until i can get the buttons working again. Any help be greatly appreciated. Ebay just refunded me for the radio they quit trying to help, all they said was to just press the reset button, which dosent help

I do not have an 8227 unit but try to help here.
With my px3/5 and T8 units, I can remap physical buttons using either a built-in app, or Settings/Car Settings menu. You may try to find out available options on your unit.
There is a Russian forum for 8227 units and you may use google translation to see its contents: https://4pda.ru/forum/index.php?showtopic=930058 .
Thank you for your response, the touch screen works when the truck gets warm, and only when it gets warm, says on ebay listing that it only works to -10 C, and well it will be awhile for that to happen here, the real problem is the no buttons work, i went to that site you provided and google did a great job translating it, but unfourtnley didnt help my problem, also the picture provided looks different then mine, im not sure how to add photos so i cant even show you what mine looks like, but ebay item 273656041408 thats the one i have
I have an 8227 device but its a hizpo not the same as yours so I dont know if you have the same options. But on mine, when you go into the about device in settings there is a gear icon you can click on which the code 8888 works so you can access deeper settings. One of which is the buttons on the front.
yes, ive tried that option, i can key into the key learn option, but it wont program any of the keys, what i dont understand is, how would changing the boot logo affect any of the keys, it is the 8888 code as you said to get to the other menu page, there is however a slider bar at the bottom of the key study option, has Chinese writing before it, i can slide it from 0-55, not sure what it does or if thats my problem
defective gps module ?
Hi everyone.
I recently bought an 8227L chinese 8.1.0 android car head unit. Everything works well, except the GPS: it can't find any sattelites. The connection of antenna is properly made, I tried to put it in different locations, even outside of my car, but no sattelite found.
Is there any setting I can change (e.g. factory settings or so)? Maybe the GPS chip is defective ? How can I get into that ?
Thanks.
hi there and welcome here, possibly you plugged GPS ant into wrong spot, i know on mine the radio and gps ant look very similar, tho im not sure if thats even possible, it is normal for the radio to take up to 5-10 min for the first calibration. You may be correct on a defective gps antenna, if your antenna has a clear line of sight and its been on for 10-15 min, if its still not finding any satellites id go with a bad antenna, but im sure theres many more people here with much more experience then myself, hopefully someone else has better suggestions

Lucky to get a full refund. lol. Go to Car Settings, Factory Settings, enter password 8888, go to Physical button study and have fun. Remember that some buttons have multiple features like the power button is power and mute.
Btw, it is very hard to find info on these units. Weird since they are awesome for the price.

Dear, I found this procedure to root: https://4pda.ru/forum/index.php?showtopic=930058&st=340#entry82160226 .
I can't download the attachment cause I can't login due to Russian.
Did you try this procedure?
Tks.
Hi I cant login to 4pda too, and I doubt this process cause I can't even connect to my laptop (not recognise / no sound with usb)

Oh yes you are absolutely right, in settings/ others/ enable USB2 debug and save/reboot at boot I can see a line at the top (don't remember exactly ... "waiting usb" or something like that.
Now I'm really afraid to try root as I don't have any backup and it's a second hand radio :silly:
Did you try rooting
Hello yes but flashtool.exe is not working on my laptop (I tried with Windows 7 pro)
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
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
Hello evryone,
I'm a bit in a pickle here, i got a smart TV (zephir store brand) that costantly loops trough the zephir logo and smarttv logo.
As far as i know the tv fuction perfectly fine until the previus owner tried to performe a firmware update, during the update something went wrong and now we are in this situation.
Till now i have tried the following:
Turning it of and on
Un plug the power and wait for 1h
Tried to perform a factory reset via remote
Tried to perform a factory reset while holding the power button
Tried to perform a factory reset while holding the power button and the volume down button
Tried to perform a factory reset while holding the power button and the volume up button
Tried to connect an usb keyboard
tried to connect via usb to PC
Nothing of the above showed any sing of response at this point the owner has given up on the TV but i still wana try to use it as a second monitor or something, so with all of that i'm coming here to seek the wisdom of the XDA forums. Any and all help would be apriciated form jailbraking to rooting, turning it into a monitor with no android fucionality, how to access the shell file anything at all.
Alright, so I couldn't find any firmware anywhere whatsoever for the Zephir brand. Tried loading a differend brand one for the same logic board. Managed to boot it but the picture was inverted and doubled. Made it to the source selection screen. Attempted to load a different firmware. The tv crashed while loading the booter. Now it won't even turn on the power indicator LED. So I guess it's well and truly cooked.
I could find the board online for like € 40 but I'm pretty sure they come without any firmware or OS? Does anyone know if it'd be worth a try, especially without being able to source the OEM firware?
Does anyone know if there is a way of making just the screen run on an arduino or something, I only need it to run HDMI anyways, 'cause I was planning on using it as a monitor anyways. The logic board is a CV538H-a.
If anyone has a suggestion I'd be glad to give it a go, otherwise i guess I'll bin it.
Hey all,
So i have this android 8 Secaine head unit in my truck. Yesterday it booted and failed. It shows try again and factory reset as options. But none of the touch buttons will move the selection. I plugged in a mouse and can scroll up and down but it will not activate either selection. It was working fine the other day. When i press the reset button it will reboot show the navigation software logo then go to the screen i have attached a photo of in this thread.
Any Ideas ? Is this a hardware failure ? Can i use a jump drive to re-flash the mcu ?
Thanks.
Well, there are 2 points visible...
Try again
Factory data reset
Seems you need to try the second one in this case.
It is written in the yellow colored part how to switch and choose.
Yes i saw that but nothing you touch on the head unit will move the selection or allow you to enable it. The touch function on the radio is gone. I can how ever move up and down the 2 options by plugging in my mouse, but clicking on one of the options does nothing.

If you don´t have physical buttons, take some USB-keyboard and use the arrow keys and the enter key.
Going to try that this weekend and cross my fingers. I have a few MCU's that are specific to this model i can try to flash if i can get it to factory reset. Just hoping the hard drive hasnt failed or the Rom is ok. It has been hot here this week.

Just get it out of the car and on your desk, connected to a 12V power supply.
That is nothing which should be done in the car, at least not if it is hot or stone cold.
