[Firmware] for the SWM8802

[samm000]

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:

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.

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:
MainWindow::CreateDLSetting(): Download sceneDOWNLOAD_ONLY).(..\..\flashtool\UI\src\MainWindow.cpp,472)

Somebody know what I´m doing wrong ?
tks

Upgade the firmware

Hi guys

first of all download this https://yadi.sk/d/gZvmllBw3WeoLz

then unzip it to desktop

then go to device manager and add a divice manual choozing the one from the file you unzip Windows_10_MTK_VCOM_USB_Preloader_Drivers_tehnotone.com

instal drivers media tek da usb vcom port
and mediatek preloader usb vcom port

you will not see any new device in device manager just add the drivers

now oper the flash tool and select the scater file ftom the swm8802 firmware folder

then choose format all +download

you are ready now just klick on the green download arrow

after you do that conect the male to male usb cable to pc and to the front usb port at the player and after conect the power cable

now it start to flash the new firmware.

what i found after instaling is that the player is 4.4.4 and its faster
it is rooted
and it needs igo to be installed so copy your igo to sd before upgrade

there is also https://yadi.sk/d/nPuSTzgB3U65b2 update.zip to download if you like this is very easy to flash
just copy the update.zip to sd and go to settings / about device / locale update and click update

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?

 

[SSRivery]

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

I just tell you what i have done.
i don't know what was the external power that you give to your unit it should be 12V and it has positive and negative
you must know what you do and do it at your risk sorry for your unit but i am writing what i have done

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!
