[Firmware] for the SWM8802

Hi,
Finally there is a complete working firmware (for sp flash tools) for the bricked or in bootloop hanging SWM8802.
If you're device is working wel, then is my advice have fun with it and do not flash it!!
If there is an update from the manufacturer i will update the post with it.
For the bricked or in bootloop hanging SWM8802 follow these steps:
Code:
1) Download Firmware, sp flash tools and mt8127 vcom usb drivers from the link bellow.
2) Extract the folders.
3) Disconnect the device completely from the power!! (I use a 12v adapter to connect the device at home).
4) Open sp flash tools and choose scatter-loading File (search the one located in the swm8802 firmware folder).
5) Press download button in sp flash tools.
[B][COLOR="Magenta"][COLOR="Red"]"Keep in mind that after connecting the power (in my case adapter),
you only have 2 - 3 seconds to connect the usb cable between the device and computer.
That is why you should already connect the USB cable to the computer or the device before starting to flash"
[/COLOR][/COLOR][/B]
6) Power on you're device.
7) Connect the unit to the computer with a usb cable on the front usb port of you're device.
8) If you have done all the steps right, sp flash tool will start flashing your device.

Working?
Since using this firmware update on the SWM8802, has it gotten bricked or stuck in a bootloop at all again? Or is it working 100% perfectly fine? Any issues you're aware of? Thanks!

I have the idea that my stereo is working beter, i used the option format in SP flash tools. The only thing is that i needed to find a navigation software because the IGO wasnt there anymore.
No issues or something that i have seen or feel in this rom. The only problem is, i dont like that i can not turn off the beep from the touchscreen in the settings.

my device does not work now does not turn on, Please help with another firmware for my swm8802
thank you

Hi, I have a similar problem with my SWM 8806 unit. I follow all the steps published in this thread but the SP Flash Tool can´t download the firmware (MT8127). It seems like a problem with the Drivers. I have installed the PreLoader USB VCOM, DA USB VCOM, USB PORT and USB VCOM in a Windows 7 laptop.
This is the log:

Somebody know what I´m doing wrong ?

I had bootloop but after Im trying this solution my device is dead after I was put usb A-A to front panel.

1] i Want to know the Antutu score of this unit
2] I want to know what GPU chip has. should be Mali400 or 450 i guess,
3] if it supports OTG

It is exactly the same with the original but faster.
And it is rooted it has super user su.
You can change the background of the radio if you change the backgroud of the default launcer the same background goes to radio.
I will try to make a video just give me time

Does this work on the swm 8802? just run the update?

Anyone tested this with 8802?

Thanks for this info, your english is not that bad!
If have been struggling to flash my swm8802, been following all the steps/downloaded the drivers/scatter files and flash tool.
Still unable to get the flash tool to run, could it be because my unit is still in the vehicle connected to power cord? Could it be that the drivers isnt installed correctly?(code 10 error with yellow sign on driver) or is it as simple perhaps the usb cable is faulty? When plugging in laptop(windows10) I dont see or hear any sign that a unit is plugged in, should I see something?
Sorry for lengthy Questions

To make flash tool to work you must first take out the unit from the car. Then have ready an external power and a usb cable plugged to the pc. Start the flash tool press download and then plug the power to the unit and immediately the usd. Flash tool must start downloading

Even my unit died after the procedure that seemed to have been successful. I can't even run the procedure again as it gives me a "DRAM" error (4032). Barnard27 managed to solve the problem? Who could help me? Thank you!

Help Needed xtrons PCD76oloa-b bricked

Hi I've had my xtrons headunit for 6 months and asked xtrons customer service for an update they provided me the update with full instructions so I followed them completely and now it boots into recovery instantly on power on. I can't control the recovery by volume up/down as they are unresponsive so need to adb into the system and reflash the original software. Can anyone provide the original img file for this unit or suggest a possible fix and advise me what software to use as I've only ever reflashed phones not rockchip devices.
thanks in advance

Need help resting my head unit

It is probably in a boot loop. What did you install or do to get it in that boot loop?
If you didn't do anything, you might try to rest the unit or disconnect if from 12V and wait at least 2 hours.
And edit your first post to change the title. I assume it is "resetting" and not "resting"

1- no I didn't do anything to it. It was working perfectly and I had to switch the car off and then turned it on the boot loop issue started.
2- how do I disconnect it from 12v? Sorry but I am have zero experience when it comes to cars.
3- and you are right it's resetting but I have no idea how to edit the title of thread.

2- Get it out of the dashboard and disconnect the harness or the power plug or take the fuse out.
3- like I said. Edit the first post. It will also make the title editable.
Do you have a small reset hole in the front of your unit? If so, try to reset it with a "pointy" thing like a needle or something else.

Try what surfer63 says, because he has way more experience than most of the people about Android Head Units on this board. If all else fails try what I did after having a bootlooping HU for nearly 4 months :S
Had the same issue. The HU (with 2 USB ports) was some unknown brand called Funrover loosely based on Joying firmware. What worked for me was
- Download the suitable Joying firmware : joyingauto.com/blog/post/joying-intel-sofia-android-car-stereo-software-update
- Extract it on the PC and then copy the firmware files on to a freshly (FAT32) formatted USB drive
- Plug in the USB drive to your HU USB port (1?)
- Since your HU is already bootlooping, plug in a keyboard and use the following key combination> Alt + Print Scr + tapping i (or e, both worked for me) to get in to recover
- Ideally the recovery option will detect the plugged in USB and start reflashing the firmware so that you will be able to use the HU again.

Android Allwinner T3P1 easyconn need help

Hi,
I am not sure what setting i have done or after updated system firmware. The easycon no longer working. Everytime i press the app icon, it went in and immediately kick out to the main icon screen.
Another issue is after updated the system firmware, the side touch panel lighting cannot be change colour. Floating button also gone missing.
Appreciate someone can help out.

I have t3_p1 1-16 Android 10 units. I reset it to factory settings. Screen mirror no longer works at all. Even the USB Car Play Dongle is not working. Is there a hero to offer a solution?

hello,
It happened to me when I updated my system, after system updating my air conditioner app stop working and also it's T3 P1 and I solved the problem.
The solution is to go to settings, car settings, extra settings ( pass 123456 ) then select car model or something related to model, then you will be getting into car selecting menu ( pic is attached for reference ).
Please be careful when choosing the car model, it should be exactly the same as yours.​after that you will get an APK downloading, also MCU update, system will be restarted automatically after updation, done
notice: your head unit should be connected to WiFi for the MCU updating process.
Regards,,

Use one of the updates for Anroid 10 and with correct resolution

I understand this now thanks but the problem is that I cant boot it into recovery or even get into the actual system because it is stuck on bootloop. I am going to try flashing the system in the morning. thanks again!

You don't need to bootup to update device!
Transfer offline update files to USB drive (unzip from file two files inside a zip file and put them only on USB) and next time system starts (USB must be attached to port) with car it will automatically start update procedure and finish.
After updating it must enter Android that is dependable on what update you will perform (right one).

Ok thank you I will try this right now and tell you how it goes!

hey I just tried to load the update on the usb then plug it it before the unit turns on but I still have no luck. the unit just stays stuck in a bootloop only showing the android logo. the reverse camera still works, but nothing else does it stays stuck on the android logo. I think flashing is the only way to save it.

You must detach canbus box from backside of device if you have cnbus at all, it is square box connected to wire harness.
