Pionneer 8227L_Demo cannot be booted by USB

Pionneer 8227L_Demo cannot be booted by USB - Android Head-Units

I'm using a Pioneer 8227L_Demo unit with
Android: YT9260_AHD_00006_V004_20191109_DSP
Android Version: Android 8.1 Go
XY AUTO: 3.2
DDR: 2G FLASH: 32G
CPU: A7.1.3GHz x 4
MCU1: 3.1 (8227L)
I've downloaded the "Stock android 9 touch firmware version 1" and extracted to a USB Flash Drive (Tried in Root and created folder "XYAUTOGPG") but I couldn't get it load during reboot of unit (I get into the Factory Setting and hit Reboot), for sure I did try to tap repeatedly during the start up but nothing comes out. I've enabled USB Debugs and one thing I'm not sure is should I set the USB Mode "Host" in the Factory Setting?? Currently it is in "Device" mode.
Please help, million thanks.

Anyone can help

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.

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.

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.

Upgrade from Android 8 to Andriod 9 (Using disassembling method)
For now it is needed to DISASSEMBLE the unit for upgrade! These actions are on your own responsibility!!!
0. You will need Windows PC/Laptop/Tablet for this procedure, please refer to guide from Chinese engineers here.
1. Install drivers from this archive
2. Short circuit the resistor to ground (there is a picture in guide)
3. Power on the unit
4. Connect USB (use Type-A male to Type-A male cable).
5. Flash the Android 9 data from this archive
6. Disconnect USB and power. Then power on the unit.
7. Enjoy
After these steps you'll be able to install any android 9 from this thread. It is needed to disassemble the unit only once.
A few videos for the reference are there and there.

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.

Upgrade to real android 10
There are 2 known ways how to upgrade to android 10.
1. Disassemble your unit and do the same as described there using the files for PX5 or PX6 depending on your platform. Also there is an instruction with pictures in each archive.
2. Without disassembling, but using windows laptop or tablet. Quite simple, but requires lots of checks and preparations. And in worth case scenario you will have to solder to the needed pins of coreboard.
!!! The upgrade is possible on motherboards rev 1.4, 1.5.2 and 1.6 (quite possible that other revisions too, but we have not enough information for now). The mainboards of rev 1.2 require disassembling and soldering additional usb cable!!!
In order to complete the upgrade we need:
- strong desire to do that and be ready to disassemble unit in case of the failure or even purchase a new one.
- USB type A male to type A male cable
- Windows laptop or tablet
Steps to do.
1. Preparation
- check the Bluetooth module that is configured in your unit: System Settings-->Factory Settings-->FUNC-->BT Mode. Note its model somewhere. That will be needed to restore the settings after the upgrade.
- check if you can do an upgrade:
-- install terminal emulator on your unit and run
Code:
dmesg | grep "USB device" | grep using
and note the last time stamp
-- plug USB stick to the first USB (on the panel or into an extender cable)
-- run again
Code:
dmesg | grep "USB device" | grep using
-- if you see something like
Code:
[ 4781.749803] usb 3-1: new high-speed USB device number 16 using usb20_otg
you can use this USB and plug the head unit to your laptop via it using USB male type A to male type A cable. usb20_otg is vital
-- if you see something like
Code:
1-1.3: new high-speed USB device number 5 using ehci-platform
This USB can not be used!
-- repeat the action for the second unit`s USB
-- IF BOTH PORTS DOES NOT HAVE OTG YOU CAN NOT GO FURTHER UNTIL YOU SOLDER THE 3RD CABLE! The instruction is at the end of this post.
- download PX5 or PX6 depending on your platform.
- if you have a display with resolution 1280*720 , download a custom oem.img, it is suitable for both PX5 and PX6;
- extract archive to root directore of drive C: You should have C:\px6_10.0_burntools\ or C:\px5_10.0_burntools\ folder;
- install drivers from DriverAssitant folder;
- in case of PX6 go to C:\px6_10.0_burntools\AndroidTool_Release_v2.71, for PX5 go to C:\px5_10.0_burntools\AndroidTool_Release_v2.71, edit config.ini, replace Selected=1 with Selected=2. That will enable English language for the program;
- if you have 1280*720 display, put the custom file to rockdev\image folder and replace the old one;
- backup all vital data on your head unit;
2. Upgrade
- run AndroidTool.exe
- download and install this APK
- run it and click "Go to Android10", the device will be rebooted and BRICKED. APK kills loader and boot partition!!!
- connect your laptop and head unit via the discovered OTG USB
- AndroidTool should reprt "Found one MASKROM device"
- hit run button;
- wait until the competition.
The unit will be rebooted, data partition will be formated and the unit will be running andriod 10.
3. Post upgrade
- download the most recent firmware
- put it on USB stick
- do an upgrade using this USB stick
Known issues and fixes
1. Bluetooth KD6 does not work on android 10. Replace the module with IVT140 or RF210, maybe it will be fixed in new firmware. Fixed starting from 202011261850
2. In some unique cases the rear camera does not work on android 10 (we suspect that it appears on old mainboard revisions without DSP). Fix is to revert to android 9 or maybe it will be fixed in new firmware. Fixed starting from 202010141730
TIPs.
Mainboards Rev 1.2 do not have USB OTG, so you have to solder the 3d USB cable. Just solder the USB wire to connector A if the mainboard. Pins 63 and 64. 63rd stands for D+, 64th corresponds D-. Do not forget about GND. +5V is not mandatory for upgrade, you can take it from rear connector H (check pin 5 or 10 there) and make fully working USB port.

If you are talking about downgrade from, let's say, Feb firmware to Dec firmware - it works. If you are looking some exotic android like 6.0, there is no firmware with old android for these units.

Hi! Rooting app contains tools for backup, but that is rather alfa version and noone tried to flash that dump back.
Your MCU is present in very first firmware available there. I, as well as xda and 4pda users, do not have 201811021951 firmware. But I can assure that Jan 17th and Pumpkin firmwares are stable. The only noticeable difference between them is in a launcher, application appearance. Also Pumpkin does not have the option that allows to set the brightness according to the clock.
Please also share the link where you bought your device.

I just wanted to list my csn2 device that I ordered at aliexpress from seller autostereo for my Mazda 5: https://de.aliexpress.com/item/-/32913733250.html
I did not do any modification so far. But steeringwheel keys do double clicks, so maybe I will try some update later.

Added to the list of devices. The case is connected with canbus adapter and fixed in Jan 17th firmware (also it is possible to fix that by changing wires, but firmware update is much easier). If you want to keep the original launcher - use Jan 17th firmware, otherwise you can try Pumpkin.

Eonon GA9180A For Chevy/GM Trucks is running CSN2. Im pretty sure its a klyde as well.
As for the static when D/L U/L over wifi. It because the wifi antenna is taped directly to the top of the am/fm receiver and not properly shielded.
I did buy a new antenna with a longer cable. One of these days i will pull it out of the truck and add the new one in and reroute the wiring to see if it helps any.(not in a rush since it doesn't bother me to much)

Thank you @dougdude10 !
Optionally instead of using google drive to transfer the supersu apk you can just sideload it through the abd connection which for me was easier and faster.
Warning: never let SuperSu update the su binary or it will not boot anymore and need to fix via TWRP or flash recovery / update.
Once root was verified I was able to install Viper4Android using this version:

ViPER4Android FX 2.7.0.0 APK Download by Team DeWitt - APKMirror Free and safe Android APK downloads
www.apkmirror.com
USB OTA update:
- Plug in a FAT32 formated USB pen with the firmware files "8227L-8.bin" and "8227L-8.upd" saved to the root folder (email: support at eonon dot com for the updated firmware files and share with us).
- Unit should detect in 30s and update automatically.
Enter Upgrade Mode :
- Plug in a FAT32 formated USB pen with the firmware files "8227L-8.bin" and "8227L-8.upd" saved to the root folder (ask your seller for the updated firmware files).
- Press reset.
- Keep touching the screen with one finger quickly until "detected" appears in green, recovery now starts.
Recovery / Factory Reset:
- Press reset.
- Keep touching the screen quickly with 5 fingers at the same time until "detected, entering recovery" appears.
- Will enter TWRP or do a factory reset if using the stock recovery and reboot after.
I'm currently working on getting TWRP setup. Without a solid backup or having TWRP setup yet I have been hesitant on trying out other upgrade files. In the meantime I have setup Car Launcher FREE which is a great alternative to the existing launcher. I have not figured out how to access the radio using Car Launcher yet, but I haven't played with it a ton either.
I plan on updating this thread once I have both official and unofficial working updates.
Feel free to share your experiences with this headunit here.
Thanks!

Hello,
I have a GA9450A, with the same processor, and Android 10. How do you manage to activate de developer mode?
Thanks

Just a FYI- Xtrons do not manufacture, they resell/OEM.

I tried that before and did not work, as it is suppose to be blocked. I'll try again and report.

So I'm encountering an issue with the linked instructions...
I get "/system/bin/sh: su command not found" when I try to run SU. I've fiddled a little bit with setprop and though the command works, setting the various properties does not have any affect...

For this, if you go to the Apps page in Car Launcher, in the bottom left click the + and then Show All Apps. on my unit this showed all the built in apps and I was able to create shortcuts to Radio and Bluetooth apps respectively.

Is anyone able to help with the above? It seems i'm not the only one experiencing the issue on the GA9450B

Thank you @dougdude10 !
Optionally instead of using google drive to transfer the supersu apk you can just sideload it through the abd connection which for me was easier and faster.
Warning: never let SuperSu update the su binary or it will not boot anymore and need to fix via TWRP or flash recovery / update.
Once root was verified I was able to install Viper4Android using this version:
ViPER4Android FX 2.7.0.0 APK Download by Team DeWitt - APKMirror
ViPER4Android FX 2.7.0.0 APK Download by Team DeWitt - APKMirror Free and safe Android APK downloads
www.apkmirror.com
USB OTA update:
- Plug in a FAT32 formated USB pen with the firmware files "8227L-8.bin" and "8227L-8.upd" saved to the root folder (email: support at eonon dot com for the updated firmware files and share with us).
- Unit should detect in 30s and update automatically.
Enter Upgrade Mode :
- Plug in a FAT32 formated USB pen with the firmware files "8227L-8.bin" and "8227L-8.upd" saved to the root folder (ask your seller for the updated firmware files).
- Press reset.
- Keep touching the screen with one finger quickly until "detected" appears in green, recovery now starts.
Recovery / Factory Reset:
- Press reset.
- Keep touching the screen quickly with 5 fingers at the same time until "detected, entering recovery" appears.
- Will enter TWRP or do a factory reset if using the stock recovery and reboot after.
I'm currently working on getting TWRP setup. Without a solid backup or having TWRP setup yet I have been hesitant on trying out other upgrade files. In the meantime I have setup Car Launcher FREE which is a great alternative to the existing launcher. I have not figured out how to access the radio using Car Launcher yet, but I haven't played with it a ton either.
I plan on updating this thread once I have both official and unofficial working updates.
Feel free to share your experiences with this headunit here.
Thanks!

Hi @****-jones, is there any update for my T8 p1 6 cores, 7 inch screen with 800x480 pixels as the photos?
Thanks,

Unfortunately, during my upgrade process (from V9.2.2_20180120.164839_KED3-5 to 9.4.1 - T8 android 9 for Phoenixsuite: https://disk.yandex.ru/d/b1lLQ2keXM_Mvw), I answerer "YES" only once!
The radio is on bootloop. When turning car power on, pressing reset and immediately turning power off and waiting for 10 sec before powering on again, it can go to recovery update, but I can't find working files to upgrade. Is there a way to unbrick my radio? Thank you so much

I have read about another way: IN CASE OF EMERGENCY (bricked): A way to unbrick is to make a link between the KEY1 cable to the METAL BOX (ground) and to reset the headunit. An UPDATE message will appear, then release the KEY1 cable off the ground.
Does it work with phoenix suite or it's the same of resetting, turning power off and waiting for 10 sec and it's only for usb/sd card?

HU boot into Update form PC mode. Very difficult operation.... I've used a needle to ground. Now It works!

Junsun V1 2gb/32gb won't boot update

Hi all,
Trying to update my Junsun headunit with 8227L_8军灿UI03-国外11_v3_20220714 however when plugging the USB into the unit, it won't boot/recognise the .bin & .upd files.
I've tried both USB ports, both ports read the USB, and I can access the files on the headunit through file explorer, however whatever I try I can't get the unit to boot the update.
I've attempted to reset the device using a pin in the reset hole, and also tried with the unit off and turn the key but the unit just boots normally - nothing seems to be working. USB debugging is turned on in developer options.
Any suggestions?
Platform: 8227L_demo
RAM: 2gb
Storage: 32gb

Did I read somewhere that you need to rename the files to remove the Chinese characters before they will be recognized? I could be wrong but worth a try.

XY AUTO 3518C

Hello People,
I have a XY3518C auto android 9.1, currently it has the XY AUTO 3.0 version, I went through https://file.xygala.com/?lang=en, to download the updates but there was updates only for Android 6.0, and 8.1; however, I downloaded the 8.1 which had the XY AUTO 3.6 version, and then I moved the files to the USB formatted to fat32, when I insert the USB to the USB port of the stereo the usb will give signal, but when I go to the system info the "Android Update" will still be highlighted and unclickable.
I wonder if anyone has any idea how to update my screen, the current UI sucks and I would be so happy if someone would help me to update the UI, or to add themes as an option to my current system.
Many thanks for considering my questions!
