STEP1 OPEN SP FLASH TOOL . FROM DOWNLOAD TAPE CHOOSE SCATTER AND PRELOADER It is necessary to choose the PRELOADER as in the picture No. 2Hi,
I think I have bricked my alps FF-5000 8227L device
I did the following steps before this happened:
1. I flashed the HU with this firmware: 8227L_8_UI04-国外11_v1_20210421 UPDATE.zip link
2. The process was successful, everything worked fine, but the screen resolution was much bigger than the device native resolution.
3. I found a possible solution (thread) in another forum, according to that I uploaded the attaced files in the zip to the system.
4. This process was also successful but after that the system didn't boot anymore. I can see only black screen with backlit.
And yeah, I don't have any dump from the rom. No backups.
I have tried to connect to device via USB cable but my computer doesn't recognize it. Also I have to find the test points so here is the picture of the mainboard.

STEP2 FROM DOWNLOAD TAPE CHOOSE Download Only PRESS Download
STEP3 CONNECT USB CABLE (4PIN) WITH PC
STEP4 SHORT THE TWO TEST POINTS
STEP5 CONNECT THE POWER 12V TO BOARD DON'T move the short when the process starts
STEP6 AFTER Download THE The device will work again
Knowing the test point, there will be no problem in downloading the firmware to the headuint, even if it is not compatible with the headuint, it will not harm anything. You can do the test point again and re-download the firmware that is compatible with your headuint, and most importantly, it is compatible with the screen resolution. It is necessary to know more specifications your headuint so that we know the right firmware for youThanks, I'm almost in the finish line but now I get an error message:

The unit has 1g ram and 16g rom.
I absolutely undersand you.Knowing the test point, there will be no problem in downloading the firmware to the headuint, even if it is not compatible with the headuint, it will not harm anything.

(Note I downloaded your update and it made my screen black and the matter was resolved by my file attached to the previous post and the previous steps explained and it worked for me without the headuint losing anything)
MY HEADUINT IS 2g ram and 32g rom. (MTK 8227L_8) (JUNSUN V1) (FF-5000 alps) screen resolution 1024x600
I will solve it for you Do you have the same attached picture NO.1I absolutely undersand you.
However that error message appears right after my PC detects the head unit com port. I think this is because the scatter file is not compatible with my 16/1g unit, the scatter file you attached can work only with your device (32/2g). So the download process doesn't start at all.
It's good to see there is a possibility to unbrick the device but now I need a compatible scatter file or at least edit somehow :S
Awesome! Based on your instructions I was able to get the unit back to life. You're a genius!I will solve it for you Do you have the same attached picture NO.1
It is necessary to choose the PRELOADER as in the picture No. 2
Make the test point in the same way as before
I am happy for you and to be able to help you, I have to know the original screen resolution in order to search for the appropriate update or the appropriate firmware and download it to the device by SP FLASH TOOL In a previous post I shared the firmware The screen resolution is 1024 x 600 I don't know if it is suitable and we need to know your device's internal specifications to determine the appropriate firmware for it.Awesome! Based on your instructions I was able to get the unit back to life. You're a genius!
Only one thing I have to fix. Screen resolution issue:

Any advice on this?
I tried the username xyauto and today's date of 13.04.2024 and 14.04.2024 and neither password worked. Am I missing something?..yes, I just noticed that.
it seems that downloading without logging in to the site has a limited download speed..
login to the carsoft and try to download this one http://carsoft.xygala.com/index.php/admin/Download/index/url_type/firmware_url/file_id/

the link takes me to the main page. and then its like finding needle in a haystack.
a bit off topic...
Updated to MCU 2.8 - automatic acc off time delay works > 24hours...
I modded the UI2 Launcher a little bit for my personal needs.
