Hi friends,

Have you are observed overheating of touch panel of your car stereo or hangs in your Android car stereo or system not responding or application keep crashing etc.

Then this video is for you. I have done this small modification in my car.

I made a small hole on sides of AC vents such that cool air blows over the heat sink of Android car stereo and two cpu fans of 12V take power supply from same connector.

Whenever the car stereo is turned ON the fans also turn ON and blow cool air over the heat sink to keep it cool.

If this was so easy...

My device works only if i do "fastboot boot xxx.img" where the image is... it doesn't matter apparently. No matter which image I boot, my radio boots just fine. I can restart and all. If I disconnect power, I need to fastboot boot again to get it to work.

Hello, I would like to ask a question to the TWRP experts, about my HU AC8227L with system YT9216C_AHD_000005_V004_20190807

I have installed the TWRP vers. 3.0.2.0, which seems to be the only one working on these radios.

I can't make a backup even of the system partition.

After less than a minute, the video freezes, the monitor wobbles and the system restarts.

Screen timeout is disabled.

Backing up small partitions like boot - lk - recovery etc does it without any problems, zip file installations ok

Has anyone happened the same thing?

Thank you all for the work you are doing.

Hello, I have a HU. I installed a Launcher, set it as default, and now it can't go to the Android menu, the Bluetooth is working fine, just a BMW logo looping. I tried to fix it, accidentally bricked it as well (deleted everything with SPF), because it's now not recognized by my laptop. I got my original firmware from the manufacturer I think (link), but they didn't really tell me how to use it. So currently the reverse cam is working, the original BMW menu is working, the Android part is a huge black screen (with black screen). I also tried to find test points, with not much luck. Can someone help me to find the test points, and tell me how to use this .img file? Only one RST button is present.

HU details (so other find it in the future)

I updated my HeadUnit yesterday. On the previous version, one from 2018 I had a dash cam recorder, chinese one, I think, that worked with my usb camera conected into a hub. After update and factory restet the app is not there anymore. Anyone knows the name of the app and where can I find it? Thanks

Hi guys just need some pointers as im confused with few things, one my HU right now has this android version: YT9218C_00005_v002_20181025_HIFI. Interested in upgrading this one as it is slow and hangs sometimes, got android auto to work on this one so my questions are.

1. Can I choose any one firmware posted via usb flash drive. also in the forum i found a smaller version of firmware which was missing the preloader and few other files. so really confused which one I use.

2. Im not sure whether my model is 1/16 GB or 2/16 gb, does that make a difference to upgrade

3. after upgrading hoping android auto and other functions becomes smoother and faster.

Hello. I bricked my Unit FF-5000 Alps AC8227L (see attached photos) and now my unit just power on, but display remain black as in the picture. I use SP Flash tools and I deleted all (I use format All + Download). But the file I have want to write is not for my unit, and now the system is bricked. Any help please!!!

I'm desperate, because I try all I know, but no result.

If anyone have these file ( pgpt, pro_info, nvram, protect_f, protect_s, seccfg, ) for making device to boot, and Preloader, lk, bootimg, arm2, recovery, sec_ro. meta, logo, misc, logo, metazone, etc... I will apreciate.

Unit seems to react on SP Tools, not want to update from that 2 file on usb/sd card (dboot.img and update.zip)because do not detect usb drive, but the red bar on SP Flash Tools go to the end, and after that, I got 4032 error. On device manager my unit it see as MediaTek USB Port (COM7).

[Android Head-Units] bhudcser:
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.

[Android Head-Units] 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,

View attachment 5592997

The unit has 1g ram and 16g rom.
[Android Head-Units] mohamed taher elbstani:
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
[Android Head-Units] bhudcser:
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
[Android Head-Units] mohamed taher elbstani:
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
[Android Head-Units] bhudcser:
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:

View attachment 5593489

Any advice on this?
[Android Head-Units] mohamed taher elbstani:
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
[Android Head-Units] bhudcser:
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):

View attachment 5593815

View attachment 5593825
[Android Head-Units] mohamed taher elbstani:
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
[Android Head-Units] bhudcser:
Okay thanks a lot. Hopefully you can find something.
[Android Head-Units] mohamed taher elbstani:
Decompress and copy it to the USB drive . Do an update And the screen resolution after the update will be 800x480

Suitable for (JUNSUN V1) (MTK 8227L_8) ( alps FF-5000)
[Android Head-Units] bhudcser:
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.

Is your motherboard the same as shown in picture? try the scatter file from 2018 memory dump .zip. you can load the memory dump of 2019 / rooted with same scatter file.
