Google maps work well in Ukraine and just awesome in Europe. Used IGo Primo for offline navigation, but Google maps even in roaming not so expensive nowadays.
thanks for the advice. I am trying the Sygic app, but unfortunately when you give me the voice information you always hear the music in the background, how can I remove it?

    Can somone point me in the right directon to buy a better gps module for my Erisin ES9791V klyde px5 ?
    US $10.69 7%OFF | 1~5PCS/LOT New original MAX-M8Q-0-00 MAX-M8Q-0-10(new version) GPS Module
    https://a.aliexpress.com/_AWofiJ

    This one suits all mainboards except rev 1.2.1. Purchased and tested by myself.

    But please note, that weak GPS signal is caused by weak connection on SMA connector in most cases. The antenna requires 3.3v to operate correctly.

    Hear you everthing on the Radio? on the Black Screen i can start the Radio app, also i hear the beep when push the buttons. I tried the 800x400 file but nothing.

    the 2nd Option to put the USB in and try to push the "OK" in Black Screen should work. But there are no effects. After Restart the Backlight from the Display was blinking.

    1st Option with the Recovery Mode doesnt work. I can´t activate the Recovery Mode. (Push and Hold the Power Button. LED is blinking. Then push the Power Button quickly. No effects.

    How can i find the other resolution Files? or can it edited from "wvga" to "1024x600" easily?

    Device works but black Screen.

    It's strange on sim4000 pictures we can see a PX6 android10 with build number 202103051220 !
    I asked to my klyde contact but she couldn't find this version ! if someone have a better link with klyde team, it could be interesting to double check !

    At first there was radio, then i tried the 800 X 400 file with the firmware update...after that there was nothing, it tried dismantle it to use the first method of shorting it, i must have did something wrong, cuz my board is dead now........ the risk is always there, was prepared before trying...

    Hello,
    I have a px6 unit and I have a couple of questions - issues, if anyone knows.
    First of all, bluetooth stops working after a couple of start ups, bluetooth name in the settings is blank and in order to get it working I have to select the bluetooth mode ( the same mode ) in factory settings and reboot once or twice. After that it works just fine.
    Also, can I use a different music player? I am used to using folders and in the embedded app there is no such option. I have installed a different app but I think I need to set it as the default player somehow?

    Try updating MCU and firmware. Also there could be a power issue. Check if the module has 3.3v.

    There is no way to set the player as default. The default music app is a part of CarUI.apk

    Thank you for your reply. I think though I have a later firmware version installed from the ones listed in the first page. I have asked the seller off course but they seem to take their time responding.

    When you say to check the voltage, do you mean on the board with the board? Wouldn't want to try that, not too familiar with these kind of things..

    New firmware:

    Somehow out of curiosity, would there be any significant benefit to upgrade for people like me whose units work well with the existing firmware except for relatively minor issues such as button binding (cannot bind multiple buttons to apps)? What would be the tangible benefits of a new firmware? Thank you so very much!

    I got an Erisin 8715V bwith A10 and updated to latest firmware with erisin launcher (thanks to the author!)

    Can i update to latest version without erisin launcher? Any screenshots of normal version? And does the normal version store fm radio names instead of frequency?

    Good evening.

    I hope I can disturb you.

    I currently have CSN2_D software on my Erisin 8791V radio. SCREEN 2

    I would like to have the latest software.
    Unfortunately I always get an ERROR. Screen 1
    I use a USB stick.

    What am I doing wrong?

    Here are a few screenshots.

      Just like me, you have a "fake Android 10" (rk3368_Android10 in the messages) on the ERISIN. I have the ES8783 and had the same error. You have to update to a real Android 10 first (see at the very beginning: https://forum.xda-developers.com/t/...2_8600_d-android-8-9-10.3912413/post-79144645). It worked great for me. You can then install any new A10. The firmware versions available here (especially the last two) seem to come directly from Erisin.

      PS: looks harder than it is.
      PSPS: the correct USB port is marked with a flag at ERISIN that says OTA :) you don't have to search long



      Hi, as I see you're from Germany, so my answer in German :)

      Du hast genau wie ich ein "Fake-Android 10" (rk3368_Android10 bei den Meldungen) auf dem ERISIN. Ich habe das ES8783 und hatte den gleichen Fehler. Du mußt erst auf ein richtiges Android 10 aktualisieren (siehe ganz am Anfang: https://forum.xda-developers.com/t/...2_8600_d-android-8-9-10.3912413/post-79144645). Hat bei mir super funktioniert. Danach kannst du jedes neue A10 aufspielen. Die hier verfügbaren Firmware-Versionen (insb. die letzten beiden) scheinen direkt von Erisin zu kommen.

      PS: sieht schwieriger aus, als es ist.
      PSPS: der richtige USB-Port ist bei ERISIN mit einem Fähnchen beschriftet, auf dem OTA steht :) da musst du nicht lange suchen

      Thanks Nicolas.

      Do you have the same Ports like me?

      3G USB and Carplay? By Cable?

      Which Unit do you have?
      no I don't have the same !
      but one of them should be an OTG one !
      you can try to search on russian forum with google translate if someone already had this kind of USB naming.

      Useful tips
      Tag [Android 8] means that it applicable to Android 8 :), the same for [Android 9]. If there is no tag, it suits both versions.


      • Factory Settings password: 126
      • If you type 888 while opening Factory Settings, the Logo changing menu appears instead of Factory Settings. Logo1 replaces "Navigation system" picture, Logo2 replaces "android" picture. Logo2 is animated.
      • Developers mode password is 237
      • Password 927 opens menu, that helps to adjust screen brightens by changing VCOM value. You can set it between 1 and 100. Be careful with that!
      • [Android 8] How to get root: Use a rooting app, alternative link
      • [Android 9] How to root
        Warning! You should be careful with that as it can brick your device once you tried to update SuperSu. Do not update SuperSu binary or the SuperSU app!!! You will get bootloop if that is updated!!! Also you have to wait until the tool completes its job, otherwise you can get no sound. If you face the mentioned problems, just re-flash your device. BE CAREFUL!.
      • Starting from android 8 January firmware there is an option "OFF" for "Power off delay if ACC OFF". it allows to keep android in a sleep mode forever. Please note that it consumes around ~9-10mA in this mode. Powered off device uses 4.8mA only (twice less than sleeping mode).
      • How to get enter stock recovery: hold reset(power) button, wait until sensor buttons start blinking, release and immediately press the button again. See video
      • To adjust the back camera brightness, just tap the screen when the camera is active.
      • Set custom logo
      • Detailed device schema

      Known issues/limitations and fix/workaround for that
      • Lost wheel key settings and radio stations in case full power loss (yellow wire). Make sure that yellow wire is not disconnected when the car is stopped/locked.
      • Sound level is 10 (12) after reboot/sleep if you was listening louder; if it was less than 10 (12) stays the same. 12 appeared in Dec 11th firmware, it was 10 before that. Not topical starting from Dec 27th firmware, now you can define default sound between 12 10 and 20 in Car Settings-->Personal Settings. 10-20 is in Jan 17th firmware .
      • buzz in speakers caused by 433MHz alarm system and USB stick remounting.
      • small buzz caused by WIFI, observed in complete silence only. Not an issue if there are no connected devices.
      • There are lots of cases when wheel keys does not work at all. The reason is in wiring. Please study the head unit manual + car wiring scheme and put the needed wire to the correct connection shoe.
      • if you have canbus adapter and wheel buttons duplicate actions (i.e you pressed next track, but 2-3 tracks were switched, the same for sound level), just flash Jan 17 or newer firmware. Also it is possible to change wiring, but the firmware is much easier.
      • if you have canbus adapter and track switching is reversed (incorrect), just go to Factory Settings --> canbus and set keys_previous_next to change.
      • Bluetooth ODBII and hands-free (calls) does not work simultaneously. At the same time ODBII and BT Music works well simultaneously. Hardware limitation, no idea for now if that can be solved.
      • Voice dialing, voice search do not work on some devices. Fixed in May 8th firmware.

      1.PX5 Firmware.
      You can combine different firmware and MCU (I.e. take the pumpkin MCU + April firmware or vice versa). MCU from Android 8 is compatible with Android 9. Mind DSP only while updating MCU.

      The factory does not provide me with a changelog! Do not ask about it.

      Android 10.


      Fake Android 10.
      It is the same android 9 firmware, but with changed launcher, radio and Bluetooth app.
      Android 9.

      The link for the most recent firmware and MCU: with DSP and without DSP. _D_ in the MCU version means that it is for units with DSP.

      All available versions of MCU are on my Google drive.

      How to update firmware on the device (without changing android version)

      I know at least 3 methods how to do that :) Use USB Stick or SD card with FAT32 filesystem for android 8 or USB Stick ONLY for android 9.
      1.
      - put the firmware (kupdate.zip + update2.bin if you want to upgrade MCU) directly to USB stick or SD card,
      - insert it while the unit is running,
      - click OK once suggestion to update appears.

      2. The same as 1, but the last point is to start update from system settings

      3. Use it, if you have a brick (bootloop)
      - put the firmware (kupdate.zip + update2.bin if you want to upgrade MCU) directly to USB stick or SD card with FAT32 filesystem for android 8 or ONLY USB Stick for android 9.
      - power off the device, insert USB stick or SD card for android 8 or ONLY USB Stick for android 9.
      - press and hold power button and power on unit by switching on ACC in your car or enable power +12V on both red and yellow wire in case you doing that on the table. On some units use reset button instead.
      - once the update is started, release the button.

      WARNING! Firmware update will remove all your personal data and settings on the device!

      If you observe the error like "header and footer of kupdate.zip does not correspond signature", just try to upgrade form another USB stick/SD card.

      I decompiled with the latest Jadx and found it will end all non-system processes, except for those in a hard-coded blacklist, which includes google maps. So it should work to move an app to system/priv-app or even system/app if it is desired to be sustained during sleep. There are apps which can do this for you on a rooted system though I have never tried them. Apparently it gets more complicated if the app to be made a system app includes libraries and I don't know if the automated systemizer apps do this for you. In my case it would be nice if Maps restarted where it left off so I may go ahead and try editing the smali.

      FYI the relevant code is below:
      It comes from com.my.manager.McuManager in MyCarService.apk. According the the manifest it was compiled with Android 9.

      Update: I was not able to successfully rebuild a properly working apk. :(

      2nd Update: With apktool set to not use aapt2, it seems to work. I commented out the call to the below function, and now Google Maps resumes directly to navigation. Somehow it didn't do the trick to remove Maps from the blacklist. :)

      Code:
       private void killAllNoSystemProcess() {
              try {
                  getAvailMemory(this.mContext);
                  PackageManager mPackageManager = this.mContext.getPackageManager();
                  Intent mainIntent = new Intent("android.intent.action.MAIN", null);
                  mainIntent.addCategory("android.intent.category.LAUNCHER");
                  List<ResolveInfo> apps = mPackageManager.queryIntentActivities(mainIntent, 0);
                  ActivityManager am = (ActivityManager) this.mContext.getSystemService("activity");
                  for (ActivityManager.RunningAppProcessInfo amProcess : am.getRunningAppProcesses()) {
                      int kill = -1;
                      Iterator<ResolveInfo> it = apps.iterator();
                      while (true) {
                          if (!it.hasNext()) {

      Upgrade from Android 8 to 9 WITHOUT disassembling.

      ALL YOUR ACTIONS ARE YOUR OWN RESPONSIBILITY!!! Nobody will send you a new core board in case of the failure! At least will not do that free of charge!

      0. All needed files are there.

      1. To perform the upgrade we need:
      - Strong desire to do that and be ready to purchase a new core board in case of total failure (~100$);
      - micro SD card slot in your unit. If the unit vendor gives details regarding the units without SD cards, I'll update this post;
      - USB stick (up to 16GB, to avoid possible problems) formatted in fat32;
      - micro SD card (again, please use not so big);

      2. Put the following things on USB stick:
      - MCU firmware that suits your device. I.e. update2.bin from the first message in thread with DSP or not depending on your unit)
      - Android 9 firmware from the first message. kupdate.zip, Again: Andriod 9!!!

      3. Do NOT plug USB stick to the unit for now, let`s make bootable SD card;

      4. On Windows PC run SDDiskTool and create bootable SD card. The manual inside of the archive, with the details, so I see to reasons to repeat it there. update.img from the archive is used there ~350Mb;

      5. Install "Android 8 upgrade 9.apk" into the unit, run it, click only the button in this application. The unit becomes a brick (temporary, till a success on step 9) - You will see only a black screen and lights on the buttons;

      6. Put SD card into a units slot, disconnect battery terminal of your car or power off the unit in some other way. Both red and yellow wires of unit should not have +12V on them !!!

      7. connect battery terminal.

      8. The unit is upgraded for the first time. Take a video of the process!!! Just in case if you fail and it will be needed to troubleshoot that. On this step you should see TWO errors of formatting metadata. YES, there should be TWO errors!! and formatting error for system.

      Video of attempt.
      The final screenshot.


      9. Disconnect and connect battery terminal one more time. The unit upgrades from SD card one more time Take a video of the process,just in case. this time there should be no errors with metadata and system!!! The last string should be "Doing Actions succeeded".

      Video of 2nd attempt.
      The final screenshot.


      10. Disconnect battery terminal, REMOVE SD card from unit, plug USB stick prepared on step 2.

      11. Connect battery terminal and the unit will complete the upgrade to Android 9.

      12. Once the upgrade from USB stick is done, the unit start running Android 9. All further upgrades will be done from USB stick without any additional actions

      Video of installing the firmware from USB Stick.

      13. FORMAT SD card on your PC, do not use it in unit until it is formatted, just to be safe.

      Been using pumpkin for few days now! Here are the few issues am facing:
      1. On connecting Bluetooth mobile, bt player opens automatically, which is quite annoying during start up when bluetooth phone is gets connected.
      2. After rooting using the root apk, I cannot check root access using ‘super su’. Even ‘es file explorer’ stops responding most of the time. Can you guide me with the root access?

      1. Try to disable option "Play on USB connect" (not sure about the exact its name, but meaning should be close to that). It is disabled for me, and I never had the case described by you.
      2. I'll capture a video, but it will be maybe next week. The tool worked on old firmware, not sure if Pumpkin is different there.

      Also I have a fresh firmware. So Mar 8th 201903081109 + MCU CSN2_03202019_103040 Stored on my Google Drive

      Works like a charm. Visible differences are in the attached pictures.
