ROM / Firmware/ Brick Recovery for 7" Android Head Unit AC8227l YT9217 YT9218 1/16GB

[AQuirkyZ]

Hello, good day to you, thank you for reading this and attempting to help me, here's what happened:
My Tecno Phantom X slipped into the bathtub from the charging port side, I took it out, dried it, opened it dried it from the inside with medicinal alcohol, left it in the sun for an hour or so, wouldn't turn on, nor charge, so I left it open for 24h, then it started holding a charge, turned on fine and everything except that the fingerprint sensor wouldn't work at all not even show in menu, a few hours later it started randomly turn off, literally randomly, could be in 5 mins or 20, could be when the display is on or not, sometimes it would restart or just turn off OR when it's in the recovery or fastboot screen, so I figured it could be something software, tried soft reset and hard reset, nothing.. I unlocked the booatloader, rooted the phone and attempted to flash a stock rom, SP flash tool would always give me the same error "status brom cmd send da fail" so I tried with ADB, I screwed things up, I flashed with fastboot flash recovery sth.img. Afterwards, it would either show the battery without percentage, or boot into "Tecno, powered by Android" and be stuck there, SP Flash tool gives me the same error as before but still detects it, ADB does NOT detect it whatsoever, I have tried so many things, nothing worked, any help would be really appreciated
Thank you for your time and attention,

Hi,
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.

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 you
(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 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

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

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 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.
It appears from the image that the screen resolution required for you is 800 x 480
All of the above are speculations because I don't know the specifications of your device

Yes, right I have not shared it yet. Screen resolution is 800x480, and this was the original firmware version in the system (before I tried to install newer):

We have to look for an update that is suitable for a screen resolution of 800 x 480, I will look for it for you and when I find it I will send it to you, but this will take some time and it may be one of the colleagues in the forum who owns it and sees the post and helps us

I wont try this because yesterday night I was able to fix the issue by myself.

Here are the steps:
* Updated the system with this file: 8227L_8_UI03_10_v7_20210814.zip
* I loaded the scatter file and preloader only to the SP Flash Tool from the package that you shared with me (in this post)
* I added logo.bin and metazone.bin file from another package that I previously found in another thread when I looked for the screen fix (attached as 8227L-metazone.zip).

I used the attached zip but with your preloader. This fixed every issues. The system looks like a screen in the attachment.

So I can say the metazone.bin is responsible for the screen resolution.

I would like to thank you for your time and your help! I got a lots of useful information and learned a lot about this chinese HU.

Hello there guys, you are my last hope. I also bricked my device by accident. Now I need the test points to solder a wire. My pc can't detect the device.
thank you so much in advance

Hi can anyone tell me how to display the speed on the UI2? I noticed that someone posted a photo with the date and the speed. I have a 9216C with UI2 installed.

Thanks!
Here is the picture:

do you know what the difference is between ui1 and ui2?

Hi, I think I bricked my device by using the exact 8227l-metazone.zip mentioned by @bhudcser
I'm very new to using SP flash tool and playing with motherboard. Is there any other way the device can be unbricked using the SP flash tool and USB alone and not doing anything in the motherboard?

hi. is it possible to change the radio app on the 9218DH unit with a dedicated FM chip? most units (for example 9217) have a built-in chip and according to everything you can make a change. I read a lot, but there is little information about the FM app for 9218DH. Thank you
