it appears it reads the unit. im assuimg you did not read genereal directions and you hit FORMAT and/or you flashed the pre-loader. you werent supposed to do that. never hit preloader or fortmat unless you know EXACTLY what you are doing. so the next question would be...

did you at any time happen to flash the pre-loader?

did you at any time happen to choose format instead of download?
[Android Head-Units] fabiusw:
I uncheched It but first time i try i got program freeze. Now im done or can get somewhere test point for this board and revive?

Im pretti sure this happened not with flash loader but by touch, was in traffic and unit was boot looping with logo i pressed rest button and got udisk error.
[Android Head-Units] sashr123:
Can you perhaps link a guide or do a guide for this correctly ?
[Android Head-Units] adiafora:
Maybe someone had problems with sound in Android Auto? It is always very quiet when I use it as navigation. Android music plays with normal sound. But the navigation is barely audible. You can't hear it at all when the music is playing. No audio settings help. The standard navigation has a normal sound
[Android Head-Units] MrJinx123:
Thank You for uploading this! it made a huge difference. Since delivered new, the built in amp never worked right. i would have to launch the fm radio to init the sound and then audio would work with other apps. Now android auto launches automatically with working audio..
[Android Head-Units] AiM2LeaRn:
a guide to do what?

to flash from hard brick using test points?

or (fix bootloop/upgrade firmware) to just flash from the start of boot?
[Android Head-Units] sashr123:
To fix bootloop and upgrade firmware from start of boot
[Android Head-Units] sashr123:
Hi , anyone knows how to enter recovery ( bootloop ) on a ac8227l jcac10003. Has no physical buttons . Thanks
[Android Head-Units] AiM2LeaRn:
you get the sp flash compatible firmware. make sure its the correct one for your unit.

install Sp flash drivers

open sp flash and load firmware, download only (do not choose format)

dont check anything you dont understand

, youve been WARNED, ASK a question if you dont understand.

this is another WARNING.. DO NOT EVER FLASH PRELOADER unless you know exactly what you are doing.

all you have to do is:

extract firmware on pc, make sure folders and files all in same folder then load

open sp flash tool

"download agent file" (usually MTK_AllInOne_DA.BIN)

"scatter loading file" (ustually named scatter.txt)

WARNING#2 make sure preloader is NOT CHECKED

WARNING#3 make sure preloader is NOT CHECKED

WARNING#4 make sure preloader is NOT CHECKED

WARNING#5 make sure preloader is NOT CHECKED

click on DOWNLOAD button

put compatible usb male to male cable in radio usb and other end into PC/Laptop (there are usually 2 ports, if one doesnt work the other should)

reboot radio using paperclip and it should upgrade, if using windows you should hear a hardware detection sound within windows and it should beging flashing, wait about 5-10 minutes and radio should reboot into Android.

Common problems of PC not detecting Head Unit are:

Unit is possibly in a hard brick and require test point method to unbrick

Drivers not correctly loaded (if on windows make sure device manager shows no error messages)

USB cable is not compatible (very common)

Using the wrong USB port (try the other usb port)

here is a vdieo, flashing firmware is SIMILAR to flashing TWRP but instead of loading TWRP files you load firmware files

[Android Head-Units] sashr123:
Thank you so much , will try this once i get a chance
[Android Head-Units] sashr123:
sorry for being a noob , where do i get the sp flash compatible firmware and

"download agent file" (usually MTK_AllInOne_DA.BIN)

"scatter loading file" (ustually named scatter.txt) ?
[Android Head-Units] sashr123:
Nvm , unit rebooted all of a sudden and is working again , even updated to oct23 update . Thanks again
[Android Head-Units] icarome:
After I installed the oct/2023 update the option to set boot image is gone. Anyone knows how should be done now? I believe the previous version, from September 2023, was a more stable than this last one. Is it possible to downgrade?
[Android Head-Units] icarome:
Never mind... I figured it out. I changed a setting in the ivi-config.ini file and the option to change the initial logo is now showing
[Android Head-Units] sashr123:
Which setting in the config ?
[Android Head-Units] icarome:
set ChangeBootLogoVisible to true in the ivi-settings.ini file
[Android Head-Units] AiM2LeaRn:
scatter file should come with your firmware assuming you get the SP flash Tools compatible firmware and not the autoupdate packaged firmware.

MTK allineone da bin comes with sp flash tools

to get firmware you can post your system OS info on the forum and someone can probably post for you the latest SP Flash firmware for download assuming its available or you can contact manufacturer/seller. screenshots are usually preferred to avoid mis-types
[Android Head-Units] sashr123:
Thanks , the unit ended up just rebooting on its own after I took out all the usb's
[Android Head-Units] sashr123:

you will need more pictures of the unit and pcb for anyone to help because posting just the chip alone is not very helpful since many units carry that chipset. but a easier way is to just post a picture of the system and build info.

@Deepcuts

Hello, when my head unit is restarted after sleep mode, the background I sent in the attachment disappears. Can I cancel the sleep mode or I want this theme not to disappear after restarting the device. Can you help with this problem? Thanks
[Android Head-Units] Umutsss:
@Deepcuts
[Android Head-Units] Deepcuts:
What do you mean by "restarted after sleep"?

While sleeping, the HU should not restart.

By theme, you mean the wallpaper? Or you have a custom launcher?
[Android Head-Units] Umutsss:
After the device is put into 3-day delayed sleep mode, it restarts when the device is turned on 3 days later and the registered radio frequency settings are reset. No, there is no custom launcher. When the device restarts after sleep mode, only the radio background (image with red equalizer) disappears and the blue theme appears. After updating again, the red theme appears. I want this radio red theme to be permanent or have the device's sleep mode disabled.
[Android Head-Units] Deepcuts:
Which

3 days of sleep is a bit optimistic.

I am lucky if I get 2 days.

The unit does not restart after sleep. It just shutsdown and does a cold boot.

Which version do you have now? I am asking because I do not see this behavior with the last one from 23 oct 2023
[Android Head-Units] Umutsss:
Yes, it does cold boot. Does this cancel sleep mode? I use the 08.08.2023 version because I like the theme on the radio. Is there a red theme in the version you released on October 23?
[Android Head-Units] Deepcuts:
Think of sleep mode just like you computer.

The way I understand this device, it uses its own battery for sleep, not the car's battery. I am not 100% sure tho.

So, if the battery cannot hold a charge for long, even if you set 3 days, it will be out of juice fast, thus will shutdown, possibly without doing a clean shutdown.

When you start your car again, it will cold boot, taking a while to start.

WIll test the red background on the radio today and get back with info.
[Android Head-Units] Umutsss:
Yes, when the car does not start for 3 days, the device does not start from where it left off, it starts with a cold boot and the recorded radio frequencies and radio red background are deleted. I'm updating again for this.
[Android Head-Units] djratza:
Hello,

Sorry if this was already answered, is Android Auto Wireless working with this update? Can I update to this directly, or I need also the intermediate updates? Sorry beeing noob on this.

Thank you,

Razvan
[Android Head-Units] Deepcuts:
Yes, AA is working.

No need for other updates. Apply directly.
[Android Head-Units] djratza:
Thanks for the reply, system is faster and AA seems newer, better resolution, faster etc. I have an issue the GPS antenna is not working, any fix on that?
[Android Head-Units] Deepcuts:
Check online for GPS jammers in your area.

If you are up north near the UA border, you might have this issue.
[Android Head-Units] djratza:
Thanks, somehow it got fixed. Thank you all for your help!
[Android Head-Units] AiM2LeaRn:
i cant find a option to change the background. how did you even change it to that red backround theme?
[Android Head-Units] Umutsss:
Hello, there is no option to change it, I did not change it, it comes after updating. @Deepcuts would look into this and test it.
[Android Head-Units] Deepcuts:
I tried to change the radio theme to red to no avail. I am unable to find a setting for it.

Also, I have never seen the radio with a red theme. Your unit might have a custom launcher.
[Android Head-Units] mcdoofhh:
Hi, I have this unit. Because the sound is terrible I want to install viper4android.

How can I root this device?

Thanks
[Android Head-Units] oberharzer:
Mod translation: Thank you very much, my radio now works better and the sound has also gotten a little better.

If it is possible, maybe the sound can be optimized a bit. Truly a dream

vielen dank jetzt läuft mein Radio besser und der Sound ist auch ein wenig besser geworden.

Wenn es möglich ist vllt denn Klang etwas zu optimieren. Währ ein traum
[Android Head-Units] Umutsss:
no the unit does not have a dedicated launcher. There is no setting option to change the theme anyway. When you update the version published on 08.08.2023, such a background automatically appears on the radio. Could you look at the content of the file dated 08.08.2023? Maybe you can find the source of that radio theme in that file.

Small PSA for owners of this HU, the model without a fan.

I was wasting some time in my car last night trying to see if I can improve the BT call quality or volume.

After about 15 minutes with the music playing at a very low level, barely audible, I decided to remove the HU from the dashboard and take it home with me for further troubleshooting.

In doing this, I almost burned my hand when I touched the back side of the HU.

And this after only 15 minutes and with ~7 degrees Celsius outside. I don't even want to think what kind of temperature this HU runs at during summer time and extended trips with music a bit louder.

So, I decided to glue a fan on the back of it and an extra small heatsink. I used two piece glue for metal.

Testing today, even after 30 minutes of uptime the back of the HU was barely warm.

As a bonus, might be a placebo but I doubt it, audio is a lot better now.

Let me explain.

When I removed the so called factory heatsink, the CPU had a very hardened thermal paste.

On one side, there is a TDA (me thinks it is called TDA but don't quote me on that) that is repsonsible for amplification and should be cooled by the heatsink. The poor TDA only had 15% of its surface covered with thermal paste, hard as a rock also.

I have repasted the CPU and the TDA with quality thermal paste and because of now lower temps, the audio is a lot better. Until yesterday, I had a lot of songs that sounded awful, with lots of distorsions, at ~15 sound level.

Today, no matter how long I waited or what song I tried playing, no more distorsions. I blame this on the lack of TDA and/or CPU cooling.

So, if you have some time to spare, I think this mod might make your HU sound better and possibly extend its lifetime.

You can power the fan from the red and black wires on the power plug.

[Android Head-Units] Esevw:
Hi everyone, I'm super glad that I was able to find this forum. I recently bought a Chinese head unit 6.9 inch model number 6288A. I hooked it up and everything seemed to work right outta the box. Only thing is it was kinda slow and android auto worked but not in full screen. Anyways I messaged the seller and was able to get a file to install to update the unit. But after transferring it to a usb stick and connecting it to the head unit, file does not start to install. I did try the august file update someone uploaded which works but i get bluetooth that drops and is slow.

So since they sent me a file I was thinking I can upload it and someone can disect it and make a running rom with a very recent update files. Looks to me September 2023 stuff. What do you guys say?

Also want to thank all the devs on here, you do an amazing job.
[Android Head-Units] Esevw:
Here is the update file that they sent me. Check it out. Hopefully someone can make it auto start like the august update.

[Android Head-Units] uruh:

With the USB stick inserted, go to MCU update uption and click update. If the right MCU is on it, it should start updating.
[Android Head-Units] uruh:
thank you very much.
[Android Head-Units] Esevw:
Hey if anyone is interested I got the install to work. I had to rearrange some files on the .rar file. I unziped the .rar file and then I copied the "autostart" folder to a thumb drive and then I connected it to the headunit and it automatically started and installed. Waited until it said usb can be removed. Everything installed perfectly. Oh and this has some recent system and mcu update files.

Here is the file if anyone wants to give it a try. So far smooth and everything works.

In my android car radio, some audio players such as pulsar, nyx and others, in the various sections such as album and artist, see the covers of the songs, they see the number of songs, but when you open them there are no songs. Same thing if you go to the songs section. What could be the reason? P.s. if I open the song from the file manager it plays it.

For me this Bricked my radio, I dont know how to restore this Any ideas or thoughts? I did the autop Update like ive done 3-4 others but this caused the screen to start having lines on it and then it went dark, Guess i need to buy a new one. Good thing these radios are cheap

My radio was 2/32

hikity variant.

I tried downloading the psflash and cant really figure out how to make it connect I also opened up the unit and couldnt find the test points that are shown in alot of videos
[Android Head-Units] Maggz75:
So a slight update on my 2/32 hikity radio, after this update posted here it made my screen not display, it had a back light, but now i think it just died all together because no matter what i try to do the spflash tool doesnt even find the device to do anything to it and the lines and backlight has went away. If anyone Has any ideas id love to attempt them, however without any connnectivity i dont think there is much to be done.

I'm sorry to see that the update did not work for some people. The file that I uploaded was for a chinese headunit single din display. So from what I am reading it may seem that the resolution needs to be changed on the .rar file, which i don't know how to do that. That is also the reason i posted the original .rar file that was sent to me directly from the manufacture to see if any devs could check it out and maybe modify it. On my end everything works good no problems. 🤷‍♂️
