Remember what setting was of IC and try with every IC setting and see if radio works with other IC types.

If not resolved, revert to old one NX6686 and try those settings with DSP effects on.

Also, I see that PROTECTION value from picture is on, take it OFF in order to gain control of settings !

Hi, where can I find the factory apps for radio and mp3 player. There were somewhere in the forum, maybe in this topic, but now I cant find it

I went through all of the IC types and tried and it still only worked with DSP off. I turned protection off as well.

hi there... can someone please confirm to me what type of IC Radio chipset these units use and model? got a problem here with static noise on my Xtrons unit... been in touch with company seller they tell me it's probably IC default Radio. Problem is the shipping costs to Hong Kong Repair center are huge and not sure if it's best option or better to buy a new unit... purchased unit in July 2020 surprised that 2 years time chipset radio broke up....

I have this unit on my IX35

I contains physical buttons and encoders for volume and tuning.

Will firmwares 8227L_8工厂UIUI01-国外11_v4_20210705 8227L_8腾实UI04-国外11_v3_20210707 work on this one ?

I want to make a backup of the existing firmware but I'm unable to get USB to work with SP Flash Tool. There is One USB on the back of the unit. When plugged to PC it does not detect the device is plugged

On the other usb there is a 4 port HUB IC soldered to the board. The CPU module is 503h-v1.1 does anyone have the pin info/datasheet for the 503h-v1.1 module ?
[Android Head-Units] Anton TNT:
Same here with me, radio application blocks a few times and freezes then in next engine start get all normal, I think problem is in key ignition wire (red one), it loses memory of radio somehow, tuner sometimes resets and don't remember stations.

Otherwise IC chipsets can be in range of 6686 up to 8702, but only one is specific for every device and must work, you must find yours IC setting in factory/RADIO menu. It's trial and error...

Hi to all.

After a long time I also saw from Aliexpress an android unit for my car Skoda Octavia MK2 year 2004. in the attached photo you can see its features. Purchased from here https://www.aliexpress.com/item/1005003737664952.html (the model AC8227L with 2/32 ram/rom). System info apps tel me the unit is Alps FF5000 8227L chipsets.

Please if you can help me.

1) Not all the controls on the steering wheel work and I do not have all the car status information, I do not have the indications of the automatic air conditioning ... I changed different options from the canbus type (different car models) but I can not find exactly my own model. Can I enter the correct data of my car model so that everything works properly?

2) it has android 8 (masked android 11), how can I upgrade it and with which rom? is it good to upgrade to android 10 or 11? will this make the unit slower? and if I upgrade everything will work fine? i don't want problems with wrong rom...

I have other additional questions I will remember them in a while and I will add and I am sure you can help me

Thanks for your time
[Android Head-Units] Anton TNT:
Hi, sorry for late response I was off for a few days ...

So, as you described problem is canbus decoder and STW write/rewrite based errors.

for Nb. 1 - choose right setings in canbus PSA setting - when you choose correct PSA number other things like STW controls, lcd controls, icons etc. will activate

Problem is in programable PSA setting for specific car, if your car is like let's say PEUGEOT 308 then you will search correct PSA for Peugeot 308 "AND" probably if not working after restart will choose different for Peugeot in a list no matter if it says other model of car like 3008 408 207 307 (and year of production of your car model is also to be considered to use with settings, maybe your year of model is wrongly set like let's say if I choose a PSA setting for wrong model like I have Peugeot 308 year 2011 and in setting says Peugeot 308 - year 2015 - it's not the same model and will not work correctly), try them all and find out which activates all functions.

After choosing the correct PSA settings scroll down a little where this list of car models are and you will see some settings on the left side regarding AC climate control (activate and put it in "ON" mode), rear and front doors, back camera, AVM icon (for ATV/DTV) etc. - there you can choose and activate all options that needs to be sent to main LCD screen, like for doors that are open , various info of state of car etc.

If I am right, you could see the canbus decoder for your self phisically and read PSA settings (if came with radio unit) - it will be written for what car models are settings intended, and so try setting for each model written on canbus.

for Nb. 2 - no need to instal any new firmwares/updates while having stock firmware on unit, correct procedure will be to install theme.apk (look for it on forum on my threads for 8227L) and desired theme for unit. No new installations and updates will correct problems for units

Only choosing the right settings and tweaking "other" menu settings in FACTORY SETTINGS mode will eventually get full operation mode for your unit. I had my unit for two years now and had come across everything and tweaked my unit for best performance.
[Android Head-Units] dedalos91:
Thanks for your answer.

I am already waiting for a new canbus box from the seller and I will try for STW controls, climate etc.

Please if you can tell me what is the correct procedure that fits my device for root?

for example this procedure without PC (but maybe with files from folder "armv7" instead "arm64" of "SR5-SuperSU-v2.82-SR5-20171001224502.zip" because of android oreo) is ok? https://4pda.to/forum/index.php?showtopic=779092&view=findpost&p=58483264 (google translate) or it only works via wireless like this procedure? https://xdaforums.com/t/root-head-unit-8227l.3855054/post-80550729 and i have find more procedures...

and if you think it necessary what is the correct procedure for custom recovery (twrp etc)?

for example this custom recovery fits to my unit? https://xdaforums.com/t/junsun-v1-t...7l-android-8-1-2gb-32gb.4192003/post-83951475

I have read many procedures for many HU models that are similar to each other but I do not know which procedure to try so that I do not have problems, I have to look for my "MCU TS907.190518 (H)" ? or depending on the android version? or screen size and the shape of the unit must be the same? or what?

I have also seen so many threads that I was confused, what is the thread for theme.apk?

Thanks in advance
[Android Head-Units] Anton TNT:
There is no need to root your device in order to put it to work more efficiently, not recommended if you don't know what your doing.

THEME and PACKS (just transfer all to headunit and install thru apk installer):

Thanks.... :) I know what root means and I have relevant experience and I always do it with my phones etc just this is stuck in the car and I can not work easily and replace it temporarily if something goes wrong like a phone, so I want to do as much as much confidence as possible. Then I intend to try to make it a little lighter to use if possible ... in general I am a bit of a guy who wants to tease everything .. :D but if you think you do not need maybe to be right as more experienced in such devices...but let me try, i don't know maybe try it and remove some google apps maybe etc

so please guide me

Hello Everyone, I'm new to this forum so please bear with me. Last October I purchased a Jeep wrangler. On my list of things to upgrade was the stereo. I found this Android head unit on amazon. Claims to have android 10 etc. I've had it installed since october 2021, but for the past month or so it refuses to remember settings, sometimes it will go days without forgetting. Sometimes it will only forget on apps settings. Torque was the first app it started to affect. Now, it forgets all settings after it has been of for more than a few minutes, even if I tell it to go into stand by for an hour. I have tried resetting it without the gps antenna attatched, something I read in the beginning of this thread. I've factory reset it a few times. I've tried exporting the settings and re loading them. I tried an update file that was listed on a google drive some where in this thread, but it won't update for whatever reason. Do I have a hardware issue, or is it something that can be resolved with software changes. I really like the stereo, but it's getting on my last nerve having to set up the radio every day.

attatched are pictures of the various info screens.

Try to remove sd card and usb stick and restart the unit, after that choose your settings and restart again and see if your settings is stored ok.

It is something like that, your settings stored on usb or sd card, you can search about that
[Android Head-Units] Anton TNT:
Or if you have music and files in SD card and SD card is always in headunit go to FACTORY SETTINGS and to menu MP MODE and choose save to SD card (factory settings and system image). After that, after any restart of unit, the image will be restored from SD card.

And what about my questions?

:)... please tell me if you know...
[Android Head-Units] beargibson3100:
*****FIXED*****🤞

I had at one time tried to change the settings in the menus to fix the issue, but it didn't help. So, like you said I just transferred my music to internal drive, removed the SD cards, and reset the HU. I set it all back up, and let it set for a while powered off. It seemed to be remembering the settings. So I again let it set a few hours this afternoon, It's still remembering this evening. Fingers crossed this fixed the issue, although I am curious as to why using SD cards causes this issue. Another annoying thing about the SD cards was that the system always had a notification in the tool bar asking if I wanted to eject or setup the SD cards. I tried setting them up which would have included formatting them. However, when I pressed the format button it was as if I just clicked off of the tool bar and it all went away. It never tried to format the cards.

Thank you for taking time out of your day to help me sort this thing out.
[Android Head-Units] dedalos91:
for Nb. 1

I have already tried everything you say (I asked the seller and I have read various posts etc), but unfortunately I had no result. So I expect a new canbus box from the seller.

for Nb. 2

I understand exactly what you are saying but I have read and searched so much that I have been stubborn to find answers, but I did not find answers either because I was in the wrong thread or because it was an old thread or something else. Thank you very much for answering me. Later I will think if I will try for root etc. So if you can please tell me your opinion because I understand that you have the necessary knowledge.

I apologize for my persistence.

You must see your working temperatures of unit, they are between -10C up to +37C.

If car is heated to much I mean if internal temperature is above high, MCU of unit will overheat liike in any computers and start to freeze or fail.

Hello. Good tutorial, step by step. I tried to do so but failed. I have a black screen after the update and I can't do anything. The computer does not detect the usb port and sp flashtool cannot send the scatter file. Could you help me? Regards.

How to pass the 4th step correctly?

4 pin + usb cable i know how to connect, but usb + usb cable?
[Android Head-Units] WojtekWWW:
Please help me my friend.
[Android Head-Units] dedalos91:
for step 4 just you need to have power off the car unit and

- enable the usb debugging in developer options on car unit

- press the download button on sp flash tool

- after connect usb cable (laptop - car unit) and after that

- connect the power on car unit (start the key on car to give the 12v electric power on car unit) and then the sp flash tool go to start ROM installation

you must use the appropriate drivers, also you can try to change cable, change usb flash drive, change usb port, change laptop

maybe your device is it not compatible with this ROM (?)

for example I used the wrong preloader file and my device bricked

luckily they helped me and I discovered the test points and was able to restore it with the correct preloader file
[Android Head-Units] dedalos91:
in order for someone to help you, it is better to provide some additional information

what exactly is your device?

you are sure your device is compatible with this ROM?

if you made a mistake and installed an incompatible ROM then you need to find the correct ROM and install it

maybe you need to do it with the 'test point' method (it's a control point on the motherboard for engineers that wakes up the device when it's dead in order to install ROM)

if your device is bricked search on the forum or on Google 'how to unbrick or how to revive FF-5000' where FF-5000 is the correct name of your device...

you can also see here (and in other related topics there)

Hello dedalos91. Thank you for your interest in the subject. My radio is dedicated to peugeot 207 this is a LJANG unit with attached screen. From general information I can say 8227L FF5000 Android 8. I did flash firmware via usb, everything went ok only the resolution changed and I used 4 files to be repaired from the XDA forum from this thread a second link . These files include

1. 8227L-8.upd

2. logo.bin

3.metazone.bin

4. preloader.bin

After uploading via usb, the device did not wake up, the screen is grayed out. I tried flashtool but the laptop does not recognize usb, I installed the drivers and I think everything is ok because I have a 8227l XYAuto test disc and it detects it. I tried updating from an sd card, from a pendrive with five fingers to no avail. Maybe I'm doing something wrong with the flashtool, I'll do as you advised.
[Android Head-Units] dedalos91:
Also don't forget to enable the usb debugging in developer options on car unit
[Android Head-Units] WojtekWWW:
Unfortunately, I can't get to the main unit because it's dead :(
[Android Head-Units] dedalos91:
Yes i forgot it

[Android Head-Units] WojtekWWW:
Thank you very much, in the evening I will sit in front of my laptop and I will try, although I am already slowly losing hope.
[Android Head-Units] dedalos91:
I was in your position too, but the situation is being corrected. what I did as I described above. they helped me in the above link on 4pda, see the posts there. give a picture of the motherboard and if it's the same as mine you can see where the test points are.

also you can see the tool that i make for the test point method

But you must have the correct files for flashing

1 - prepare the the power source and the cables (from the car or at your table from a 12V charger) and prepare the motherboard (remove the screen etc)

2 - turn power off the radio (no power on mobo)

3 - connect the radio to the computer via usb cable

4 - prepare SpFlashtool and click download

5 - close the test point with a special tool

6 - turn on the radio (give 12V power)

7 - disable the test point after the SpFlashtool red line

Why would you refalsh software if has softwre working now? Is anything not working on device ?
[Android Head-Units] sheerness:
since installed every time i get in to the car and put the key in the system does not start, just a black screen, i have to pull the fuse each time for it to come back to life,

i have now found a quicker option which is to put a pin in the reset hole for it to boot/screen back to life,

the other issue i have is say that i am watching a music video say on youtube music the sub/amp sounds like a normal speaker untill i press home screen then the bass kicks in, and i can go back in to the video and will be ok till the next video. not so much of an issue just a pain, but the main issue is the black screen, so i am hoping a reflash/upgrade will fix the screen issue if not others aswell.

again thank you so much for helping me with this,

[Android Head-Units] Anton TNT:
Apparently, but untested, your device uses same 8227_demo software like mine its a CHS source android 8.1 that tell's fake android 9 or android 10 (Chinese market trick). I think this software below might work, but, install on your own risk cause I have no way to test this !

https://drive.google.com/file/d/1Ta2vL7Fc8tWmzmRxaJ-JMYGmlYYnRmud/view?usp=sharing

Download, then unzip these files and transfer on usb/sd card, put it on device, turn ignition key/ wait device to load and go in settings and hit update android. If not updated inside OS, while device is booting up(before booting put usb/sd card with new software in usb port/sdcard slot), tap with finger on center of screen till screen says "detected", then just follow install process and do not turn off anything til you see android up and running again.

Well will try this out first , if not helped or you got stuck let me know.
