can anyone tell me that how can i get the brightness bar in notification panel
[Android Head-Units] Anton TNT:
impossible , only with some addition program app
[Android Head-Units] devil9899:
like which apps
[Android Head-Units] Anton TNT:
That is dependent of Android version you got for head unit, phone's Android and automotive Android softwares are not the same.

Newest car head units with Qualcomm processors has this abbility in notification area, older units have slider in car settings. For older units as far as I know, also it can be called by specific pin code (entered in pad in infotainment / system settings - like 8888 is for factory settings, pin code 1 - 22 are numerous codes for accessing variety of controls - except 4 this is hard system restart don't use that).

If no accessed find solution here : https://tweaklibrary.com/best-screen-brightness-control-apps-for-android/

Hello

Just got this headunit so,

Not sure if there is an update for my stereo but the one I have little to no car setting and at times the audio is very low.. any help/info would be appreciated.

Also Only when I've download Nova launcher and I got access to car setting/ logo setting but no logos. It say set path and no matter what format I create can't seem to select a logo, always shows "please select contain image directory".

I'm confused.

Much appreciated 👍
[Android Head-Units] Anton TNT:
In newer car multimedia devices Chinese merchants does not allow users to change animation or logos, car manufacturers forbids them to use their logos, that's a fact for now.

Second... Low memory is a flaw in design for this MEDIATEK chinese devices with AC8227L processor and chipsets.

You have a newer Mediatek chip device JCAC (search for JUNSUN firmwares V1 or V2), you should still find the correct firmware for your radio and install it. Firmwares for this kind of device are here on this forum and on Russian 4PDA forum (use browser translator to translate from Russian language).

See also that some application like "Google services" - apps associated with Google isn't responding well and causing low memory problems. I would deactivate some not needed Google services (DEACTIVATE in settings / Google) and then see if it become stable.

You can also update software online with this OTA update (must be connected to wifi or 4G network with active internet connecton). Saw that on one of the pics. Local update is update from USB drives - offline.

For setting a LOGO from specific folder - you can try set it thru factory advanced settings - use pin code 123456 on key pad when pressed next to HMI in infotainment settings - some kind a wheel icon.

code 8888 - factory settings

code 123456 - advanced settings

code 7890+hour of the current time - developer settings (only for proffesionals)
[Android Head-Units] DRayza:
Alright, thanks much for the information

Much appreciated.

In regards to the update- I not sure which version I have and if it good enough, plus I know it isn't android 12 but it shows 12. All the talk about updates seems a bit confusing when it comes to this and more. But I would be willing to try one with a lil assistance and guidance..

On the logo and setting though, I've tried the codes in setting-factory setup and the don't seem to work.. the only on the works for me is 1234 and it brings me to this.

Note: seller told me "because the car logo will be complained of infringement , so now all models can not support to set the car logo."
[Android Head-Units] Anton TNT:
There must be some kind of advanced system settings included (in which are all settings to configure) in unit , you must find it on net or ask the seller pin code for this to access asnd configure correctly.
[Android Head-Units] DRayza:
They claim "sorry, can not set logo" papa
[Android Head-Units] Anton TNT:
I would search the net for codes for your device, someone has it or know the codes for sure, on forum or on youtube channels
[Android Head-Units] DRayza:
Ya I'll search.. so far only found 2.

1234-factory setting

5678-settings..

Oh I just found this other on. 56789

I don't know what it's for. I check car setting below and it brings me to the same setting I had access too via another launcher.

So seems this is the logo setting.

Back to my same issue of how to set a path to choose a logo.

I've tried normal photo, jpeg, bmp, zip, PNG, eps, gif, cdr. 🤷🏽‍♂️

It always says "please select contain image directory!"

So can someone help with a way to go about this?
[Android Head-Units] MrReis:
I have an AWESAFE HU with the same specs as yours and I also am now having problems with AA (using HUR). When you say you "saw that recent units with the same specs includes a firmware with Android Auto," do you mean it has the same functionality as HUR? That is, you wouldn't need HUR to run AA from your phone?
[Android Head-Units] Dygerydoo:
Yes, some new units include android auto auto installed. But unafortunately manufacturer never replied to any of my emails. I lost a lot of hours trying to update the unit or configuring HUR without success. Ended up buying an Atoto S8 Standard and now all works like a charm.
[Android Head-Units] Anton TNT:
I changed my logo manually despite seller says it is impossible to change on new devices.

Go to FILE MANAGER app on head unit. Find folder that contains your boot image (default one - search by image you see at unit startup - it will be somewhere in ROOT/main folder three / Android / data). Now, when you found it, copy that file (it will be named logoxxxxx.PNG or something like that) to usb drive or SD card , open it on computer with some program for image editing. Download or import your image that you want to install as logo to that .PNG file and save it as this one - default one - no renaming ! (otherwise it will not recognize the file at unit startup - and first before all copy default logo image that you picked up from head unit as backup in different folder on a computer in case something goes wrong).

Then copy that saved image file back to head unit where it was, where you found it. If changed or replaced by new image unit will start with this one next time. That's all. It's tricky but only way.

Hi everyone

Please help me

I need the latest firmware for my head unit

🌹🌹
[Android Head-Units] DRayza:
Ya it is tricky, because I'm not seeing any files but I'll do more research and wait and see. Maybe someone figure it out
[Android Head-Units] Anton TNT:
Install then FILE MANAGER+ app from Google playstore and then you will see all files.

I don't think you can't see all files, native file manager app is built in every headunit to see and transfer files. Maybe inactive but it's there.
[Android Head-Units] DRayza:
I did download an alternative file manager app. X- explore.

Maybe I need to root the device in order to access it, idk, but files don't have anything of value in android/data, just apps.
[Android Head-Units] Anton TNT:
Sadly unit is not rooted so access for root folder is denied as seen in image. Ah.

Can't help anymore. Unit must have all access / root to change. Unit is limited for changing things.

Altough root procedure is somewhat tricky it is manageable.
[Android Head-Units] DRayza:
Ya I figured would have to be rooted. I'll look into it. For now I guess I'll have to settle

I downloaded and used the "

MTK 8227L_8.rar", it cannot be started after flashing, and the screen has been black. I found another available wire brush pack ready to re-flash, but I couldn't enter flashing mode. I did this, holding down the "reset" key, powering on, ATC_Flash_Tool no progress was displayed, and the computer did not respond at all. Is this completely turned into bricks?

我下载并使用了你分享的“

Any way to fix this or better to reinstall original firmware with was 8227L_8_UI03_11_v4_20220629? i read it has to with license.dat file. can i extract file from 11 v4 firmware and put ir on this 12 v2? Is there any other firmware i can try?

thanks!
[Android Head-Units] Anton TNT:
I have UI3 will paste when arrive home... Must find it. Error with ACTIVATION is common for wrong UI interface. Yours must be UI4 (2019) or UI 1 (older models 2016-2019)

It probably will work in yours, you can try it. if not revert to old one.

I have another one... https://drive.google.com/file/d/1Iphu0mS2u-flKB7nx6ogaSFLRhSdrkXO/view?usp=share_link

This one is Android 11 UI4 2021 , you can try it also, no harm will be done to unit. If not good revert to old.

If still not satisfied with either of these I will send thru mail or upload to my google disk , have bunch of this updates somewhere on my HDD, untested but will work.

Here are also some apps that would be usefull to download and install via APK tool inside unit :

[Android Head-Units] ahmed.emad20:
Put it directly into the usb stick root directory and it should capture that on next boot.

I guess you should be aware that you shouldn't have a boot image in there I guess as not to get taken into a sys update thing

Hi all, need some help!!!

Bught an Android radio, don't even know the name... already imagined that it could be problematic but still took the risk for the price.

The truth is, he has some problems that solved, more or less, but there is one annoying that can't overcome, the vendor support doesn't seem to be able to solve it either.

if any one have any clue for this issue

The radio some times on boot goes to: Detected to recovery Now.... And wipe everyting

This happens randomly, if drive the car for a few minutes and then turn it off, or if i navigate in settings and do some save and restart.

Next radio boot starts with: Detected to recovery Now.... but its ramdomly not happend always, didn't figure a pattern.

I believe this is related to not proper shutdown, i guess. Any one had this problem or any ideia to solve it?

1 - Car battery its ok

2 - Did radio reset defaults

3 - Even new firmware from vendor, but still same problem.

4 - Even Can bus disabled ( to improve radio performance)

Actualy have a new firmware .V4 but has the activation issue and did a roll back to old one .v2, it has no problem with registration but... problem remains
[Android Head-Units] DizXDA83:
try a factory reset.... or firware reinstall
[Android Head-Units] JIm_stos:
Already did, not worked. Restored old firmware still same
[Android Head-Units] Anton TNT:
Hi...

First, I would check for some leftovers of installation files - .log files or factory_settings.ini files (.ini files) or something like that in root / main directory, it must not be there. delete those files and restart. Then see if unit goes again in recovery mode.

Second, check your CANBUS (if you have any installed / attached to unit) box compatibility, some canbuses don't work with some units. Try to use new canbus with different vendor , ask seller to provide you with correct canbus for your car model / year and canbus settings for it to configure in factory settings area of the unit.

Third, check for calibration of screen - unit recognizes as five fingers touch in boot of unit as recovery mode, so it enters in if recognized - prevent this by performing calibration of screen (calibration of touch area and seting right resolution and DPI settings) , find a way or correct access for calibration of screen (usually is entered by holding all five fingers on screen when on main desktop in Android).

Try that first , fingers crossed.
[Android Head-Units] JIm_stos:
Thx!
[Android Head-Units] JIm_stos:
Thanks @Anton TNT for the tips, wouldn't have thought that approach!!

But yesterday, in desperation and after consulting the old threads in this topic, risked installing a rom that you made available for @DizXDA83

https://drive.google.com/file/d/1Iphu0mS2u-flKB7nx6ogaSFLRhSdrkXO/view?usp=share_link

And get shocked!!!!

It worked perfectly, physical buttons ok, no registration problem, only the radio stations did not get saved on radio.

Then overcomed it with developer mode access and let radio store data on local drive, it resolved the issue i gues...

Also beleave that the shutdown issue may have been resolved, the behavior of radio changed, now when remove car key or reset the radio (code 1414) it changed behavior, now looks like is doing a proper shutdown.

In a couple of days will note if it get resolved or not. :)

If resolved, have another issue that will need your precious help (can bus...) by now is disable, when configured it again radio gets a terrible delay on everything, even on physical buttons... (beleave this guy is not the proper for this radio)....

But first things first and let check if the reset thing is overcomed!!

Thx for you help!

@Anton TNT

First and foremost... Your dedication to this thread is unparalleled. Truly thank for for single handedly supporting an entire community platform that quite frankly has very little English support.

I used this thread to fix my Prius stock replacement unit and flash a different firmware that has until recently been incredible.

However. The com.ts.mainUI8 app is now crashing over and over again in intervals which is causing audio to crash and my knobs and buttons to stop responding for extended periods. My unit is rooted and recently both mainUI8 as well as otg apk started pinging root constantly.

Was working for months perfectly.

In my car I have a consistent internet connection so my head unit remains connected and I fear that one of the stock apps may have either contained some sheisty malware or something else is causing this crash.

I rooted to disable or uninstall as much as possible to speed up the device ...

...I'm in bed now but I would love to pay you for some of your time to resolve this issue - and get a more thorough understanding of this platform from someone knowledgeable as I do NOT want to get a new car any time soon... and this head unit ironically is going to be the death of me.

I'd also be down to help you finish that website you never finished.

Shoot me a DM at your convenience so we can arrange a zoom or Google meet and again - thanks for your unwaivering support on this thread.
[Android Head-Units] Anton TNT:
FIRST, THANK U FOR SUPPORT !

FIRST SOLUTION: If main UI process is crashing , there is nothing much to do except find a original or some other matching firmware (update thru USB drive) and install it again and all stock apps with it. This does not delete personal files in memory so if you have some pics or music files it will remain on disk after installation.

SECOND SOLUTION: If you somehow installed com.ts.mainUI (and this installed wrong file/process is intended to work with some other unit) process accidently and need to repair it, just install again same process thru apk installer app inside unit, you will find it on this thread in earlier pages as com.ts.mainUI8.

Try and report back afterwards...

Fingers crossed.
[Android Head-Units] Anton TNT:
I'm glad things are getting on better.

For Canbus - choose appropriate settings for your car model and year and restart unit, try also with other models and years of same car (like if car is Peugeot 308 try settings for 408 or different year of production but same model 308 and so on...). If not working with all settings tried then you must replace a canbus box with better one - use HIWORLD or SIMPLESOFT canbus boxes, they are much more stable with some units.

Play with it and report back here afterwards.
[Android Head-Units] JIm_stos:
Hi Anton, i'm so dissapointed :-(

Did again:

Detected to recovery Now....

And wiped everything, Agama, radio stations, phone paring etc.

Jut don´t have idea what is wrong, just want to stop this thing happening
[Android Head-Units] monsieurtalbot:
Thanks for the prompt reply!!

I used titanium backup to freeze unwanted apps and cleared cache for everything.... Cleared data for UI8...

In the past, clearing cache at the recovery level fixed things like this on phones... I don't suppose there is a similar feature in the recovery on these devices or TWRP is something achievable...

I spent all yesterday archiving the page numbers of posts of relevance... and archiving all the shared firmwares thus far... I fully intend on putting this all into some sort of explainer video as that's a strength of mine and I feel this community needs to understand this visually (and without having to read 35 + pages)

Let's find a time to chat! Let's get this to a point where you can monetize it because you're doing the community a huge solid.

Cheers! Will try your suggestions!
[Android Head-Units] monsieurtalbot:
One thing I haven't seen is a post about how many fingers does what to enter recovery... Tapping or rubbing up and down is how I've initiated updates but what do 2, 3, 4 ,5 fingers do by comparison... 5 I read is a factory reset?

This info is very scattered in here and it took a long time to decipher (what I think) is all of it.

Guess th
[Android Head-Units] Anton TNT:
Usually is - for fingers:

1 finger tapping on screen on boot - entering update mode by offline (from USB / SD card)

5 fingers holding at boot - recovery mode (erases everything and sets as factory default)

In Android - when on main desktop area :

Holding 1 finger at each corner or all 5 fingers (depends on unit model) on screen - calibration mode

Codes or PINs are different thing - they are entered on a pad pressing the wheel icon in system info settings

You mentioned code 5 or 4 -

Code 4 is cold system restart - MCU restart, 1414 is system shutdown (with saving all data in memory)

Code 5 - I don't know what this does , on my old unit it does not do nothing, hangs

Code 1313 I believe is a radio app reset

Code 5678 - logo set

Code 8888 or 123456 - enter factory settings or advanced settings
[Android Head-Units] Anton TNT:
Yes too much data and pages to follow and read, so I decided to put this on a single web and help others in that way , idea was to film procedures and steps for helping but that's a long shot even for me, I have work shift and don't have much time to devlop a web this size so its going to slow, but eventually it will be done (and as time goes on and new units are introduced there is so much stuff to gather and manifest it).

We will try to chat and solve your problem but as told, have work shifts and so little time (with my house works also included) so till this saturday or sunday or some other free day.

I cannot guarantee I will be available to chat, for now only thru messenger or viber apps (send your phone number at wdi.anton@gmail.com - will add you in viber conversation).
[Android Head-Units] Anton TNT:
No problem, we will solve this thru diagnostic of whole unit

There is a hardware malfunction here obviously if unit is constantly going into recovery. I think that you probably must update system. Please specify hardware info of device. HMI MCU etc.

Also , first you can install and try this hardware diagnotic program https://xdaforums.com/t/best-hardware-diagnostics-apps.3316546/ it is for phones, but head units are similar in hardware.

It will diagnose system and tell which component is malfunctioning or with errors.

This problem reminds me of my problem I had on very beggining when I bought first unit:

on my old AC8227 unit (have topway TS18 now) that I have stored in my garage and testing firmwars and stuff on it, there was similar problem with memory and whole factory settings portion of device was reset and set to "ZERO" - all configurations and settings in every menu in factory settings - it is corrected with new settings entered , in every setting, in every menu of factory settings area. RADIO AUDIO VIDEO OTHER menu etc.

First of all, Thank you for your patience and for the time you spent helping us, I know how much time it takes in our personal lives :-)

I have hope and patience and with help we will solve the problem!

In fact, the FW I've downloaded from your link is much more stable and fluid than the original one.

Question:

Can be the issue related with the stand by time scheduled for an hour? the car could cut power after X minutes and cause unproper shutdown? my Audi A3 could have this behavior to prevent battery discharge.

In fact, if i'm using radio or interior light with key in zero position the car makes power off to all after 5 minutes.

So I thought about it and put the stand by time in 0 minutes.

And for all day it seems to do shutdown correctly and had zero data wipe.

But in the original FW i've done it before and got same problem.. but this new FW as i said has a diferent behavior when shutting down.

I'll keep testing to see if I can spot a behavior that at least, makes the data wipe and then do reverse engineering and find the source of the problem.
