Bro help!!! I bricked mi HU is on black screen, but flash tools can see and with test point I can connect, but don't have a valid firmware in .img format

@Anton TNT
[Android Head-Units] Anton TNT:
You have not bricked your device with updates, only if you install different ROM for unit.

Will paste as new link of some other firmware update and you try to install again using USB drive. Must find some old stuff firmware for JUNSUN.
[Android Head-Units] Anton TNT:
If you have canbus box that came with your multimedia unit replace it with new one and stable one. This one obviously interfere with car functions.
[Android Head-Units] camargod20:
Im a dumb, I tried to root and flash a recovery mod. with sp flash tool. and brick it
[Android Head-Units] Anton TNT:
Nice work then... you should go to other forum pages about bricking / unbricking devices. Good luck.
[Android Head-Units] ptgiuseppe:
Hi, sorry to bother you, what is the best firmware in your opinion for my 1GB RAM unit? The one dated December 7 2019 with ui4, is very light.
[Android Head-Units] camargod20:
Thanks for your help bro. 😁😁
[Android Head-Units] ptgiuseppe:
Hi everyone, a strange thing happened to me a little while ago, that is, after having deactivated the rear camera, the CD player program opens.
[Android Head-Units] YİGİT1940:
Hello, can you help me update my GPS with the following features and make it work? My GPS is not working. I bought 2 different GPS antennas and changed them. The problem is the same. I am looking for a new update in which the GPS will work. Thank you in advance.
[Android Head-Units] marchnz:
Check internal cable to gps module
[Android Head-Units] Anton TNT:
The one latest from 2023 should work fine. Find a link to this firmware somewhere in this thread, older pages, go back a few pages... You should see it.
[Android Head-Units] Anton TNT:
I would first check rear jack port of gps antenna if it is faulty. Second, try to reset gps settings via debug code (pin for debbuging mode - I forgot this one but there is a pin codes thread for 8227L units somewhere).

Also, to mention, if you have installed led lamps in your car, they interfere with gps signal if they are not having canbus for lights.
[Android Head-Units] YİGİT1940:
Thank you for the answer. I don't know the debugging code, let me investigate how it is done, GPS finds only 1 satellite. I bought 2 antennas, both of them are the same. I put only 1 satellite antenna on the front console. I put it in different places. It is still the same, only 1 satellite.
[Android Head-Units] YİGİT1940:
The interesting thing is that in the software I installed, the GPS settings are empty. I go to the settings. The folder is empty. There is nothing in the GPS settings folder.
[Android Head-Units] Anton TNT:
What firmware do you use , your HMI of device ?
[Android Head-Units] YİGİT1940:
Bunun gibi
[Android Head-Units] YİGİT1940:

[Android Head-Units] Anton TNT:
install latest from 2023, will post a link now...
[Android Head-Units] Anton TNT:
THIS IS THE LATEST PATCH / UPDATE for 8227L units dated 2023/07/14

I uploaded it and shared here for downloads.

https://terabox.com/s/1JSZCCoTvF4lTuQ3XYCMsOg

Enjoy everyone.
[Android Head-Units] YİGİT1940:
Thank you very much, I hope the GPS works. Do you have a home screen image of this software?
[Android Head-Units] ptgiuseppe:
Hi, I just installed it but it asks me that it is not activated, what can I do?
[Android Head-Units] YİGİT1940:
did you solve the problem? I will install it. Does the GPS work? Can you please share a picture of the main screen?
[Android Head-Units] ptgiuseppe:
Hi, I didn't solve it and so yesterday I installed the extrons ui3 firmware of February 2023 8.1 that Anton Tnt kindly published a few pages ago and you can find the link to download it there. This firmware works perfectly on my 8227l unit with only 1 GB RAM and does not require additional activation the GPS works great I use organic maps. Leave that firmware alone I recommend you install this extrons. As soon as I go to the car I'll send you some photos.
[Android Head-Units] YİGİT1940:
There are no bluetooth problems, right? Can Play Store be updated and programs are downloaded without any problems? Thank you.
[Android Head-Units] ptgiuseppe:
So Bluetooth works, I downloaded a few apps and they work very well. The problem with the Play Store is that once updated together with Google Play Services, my car radio slows down too much, perhaps also because I have little RAM and to resolve this I deactivated Google Services. I don't need them anyway, for the navigator I can also use it offline with organic maps.
[Android Head-Units] YİGİT1940:
Teşekkür ederim. Uygulama linkiniz var mı?
[Android Head-Units] YİGİT1940:
Thank u
[Android Head-Units] YİGİT1940:
It is asking for an activation code. What is the activation code of this software? How can I fix this problem?
[Android Head-Units] YİGİT1940:
I would like you to send me the link and main screen image of this software.
[Android Head-Units] Anton TNT:
and for

YİGİT1940​

Find a license.dat file on 4pda forum and try for activation over internet (restart unit , connect unit to internet while USB drive with only license.dat file is on and let it activate).

I have some licende files somewhere on my computer but they are outdated, probably won't work. In earlier pages on this thread someone mentioned and psted a link with license files. Roll back and search for it.

I'll paste here old licenses if any of you can't find anything but use it on your own risk !
[Android Head-Units] Anton TNT:
LICENSE FILES for download (dated for updates from 2022):

https://drive.google.com/file/d/19bcLeZ6Ul2zkGpMiF4GeaQSqNdF06DQ0/view?usp=drive_link

NOTE: "how to install" is on the word document included in rar file , also to mention - the only file on the USB drive / SD card inserted into unit and while activating over internet must be "licence.dat" file (and must not be in format 1licence.dat or 6licence.dat etc. - RENAME it to licence.dat when on USB drive or SD CARD)
[Android Head-Units] MierdaAutorradio20:
Hello, can someone help me get the external buttons on the android 10 radio code 8227l 2Gb+16Gb to work again. The touch screen and steering wheel controls work perfectly. I have restarted it, restored it to factory and it does not work. Do I need a code to activate? The seller does not give me the solution. Please, someone answer me. I have seen similar cases on the forum but they do not provide a solution. Thank you
[Android Head-Units] Anton TNT:
Ask your seller to provide you the files for buttons (later you must import this files thru factory settings / button menu)
[Android Head-Units] MierdaAutorradio20:
I have already contacted the seller and he does not give me any code. That's why I wanted to try to get help on this forum. The only thing I have been able to get is a firmware update but it has been of no use. Can you help me with this, how to achieve what you are telling me and how to do it? Thank you very much for answering and helping me. All the best
[Android Head-Units] Anton TNT:
Please go to factory settings area (with pin code) and take a pic of menues and inside button menu if you have that.

Buttons in front of device too...
[Android Head-Units] MierdaAutorradio20:
Hello, sorry for the delay in answering. I show you the photos you asked me for. The button menu (touch study) does nothing, it does not work. Thank you very much, I hope you can help me.
[Android Head-Units] Anton TNT:
Sorry, I wrote wrong name for that menu, menu KEY is for importing files for physical buttons.
[Android Head-Units] MierdaAutorradio20:
There's no menu called KEY. At least as far as I can see. Is there a way I can access that menu or any alternative to it? I hope you can help me.

Thanks in advance.
[Android Head-Units] arcatarc:
Try flashing this in flashtool: extract the zip in a folder and select MT8127_Android_scatter included as scatter file.

This is the partition conteining the hardware key buttons on my Hu that is very similar to yours.

I strongly reccomend you to keep screenshots of Menu and Submenu before proceding with flash in case the values are modified so that you can restore them.
[Android Head-Units] MierdaAutorradio20:
Hello thank you very much. Can you show me exactly the steps to make the flashtool you mentioned, please.
[Android Head-Units] MierdaAutorradio20:
Hello, I think I know what the menu you are referring to is this? When you press it, this image of the SD card and keyboard appears.
[Android Head-Units] Anton TNT:
First picture , menu is on the left side - " KEY " - go inside that menu and with press button import and import needed files in order to get buttons working
[Android Head-Units] MierdaAutorradio20:
I don't have files for the physical buttons. Do I use the arcatac thing or can you help me get it, please?Thank you.
[Android Head-Units] sharkyslro40:
Hello to all. I have full rom image for my FF5000 device. I can split ROM into file for SP Flash Tools, but on scatter file (software for creation scatter file , preloader and individual file for SP Flash Tools, is WwR_MTK_2_51), I can not select PROTECTED, INVISIBLE and BINREGION partition. That "unseen" partition not appear on normal scatter file. If I modify value to TRUE on WwR_MTK_2_51 program, on Scatter File tab, I can create scatter that have that hidden file. But SP Flash Tools can not load that custom Scatter. If anyone know how to write ALL FILE, INCLUDING THAT PROTECTED FILE, or have special software that can write all the file, please share with us/me.
[Android Head-Units] sharkyslro40:
Hello. Please send me your ROM image. I try with another ROM, but not work. Please send me your backup. militarucristian@gmail.com
[Android Head-Units] Gregm60:
I have one of these units. It's one with the MCU that shows up as TS907. It's branded as an Xtrons and like most of them, It has a case of the uglys. Also the firmware seem to be pretty seriously out of date so I wanted to upgrade. After doing a bunch of digging, I found that the Junsun V1 (not pro) firmware worked fine on the system. While it's still ugly I found a work around to be able to use the AGAMA car laucher app mostly succesffuly. Mostly, in that the stock music app does not inegrate with the laucher proplerly but I fixed that by installing a differnt music player. I was able to get AGAMA laucher working by installing a couple of the apks found in this thread....https://xdaforums.com/t/junsun-v1-start-equalizer-aux-bt-music-from-launcher.4237797/

I now have a radio that I am mostly satisfied with. If I remember right I only installed C500Music, Equilizer and C500Radio apks. A couple of those are found in the car_apk.zip file. Hope this helps someone.
[Android Head-Units] Anton TNT:
Try with rufus intaller it is good installer for windows linux and other oses and can write partiotions on single usb stick. Download from https://rufus.ie

p.s. you must turn on all linux partitions in order to boot from stick (at format)
[Android Head-Units] sharkyslro40:
Rufus is an utility software for Windows, and not for Android file system. Rufus read Windows files, Linux, and Mac OS. Is not meant to write specific partitions or system file from Android device. Im IT tehnician, and I know how to handle windows/linux partitions, but for Android file system is much harder to write/read. If you d'ont have special software for writing and the correct file system, d'ont try to write anything, because it will brick the device.
[Android Head-Units] Majkyork:
Hello. I reinstalled the firmware provided by the vendor. Well now I have a problem that I can't install the dvr camera. I still jump taulka: There was a problem parsing the package. Can you advise me what to do about it so that it can be installed?
[Android Head-Units] Majkyork:
So I solved it myself. through the settings with code 8888 I got to the advanced settings and in the settings others I found INSTAL and with the help of the code I found on this fore (3234) I changed to enable. if he helps someone.
[Android Head-Units] ramunsa:
So i bought my unit from Ebay it is 16GB. Which folder do I pick inside MTCD/ PX30, PX5, PX6?

is there a way to do a full backup before trying to mess with it? Few years ago i tried with USB cable but I could never get laptop to recognize the unit.
[Android Head-Units] Anton TNT:
Hello, this unit is similar like mine, software is lookalike.

FOR UPDATE SOFTWARE - if chinese android 10 install from : https://drive.google.com/file/d/1Ta2vL7Fc8tWmzmRxaJ-JMYGmlYYnRmud/view?usp=sharing

That is original software for demo 8227L userdebug

If you are going for clean install with rom wiped out and want superuser/root , choose from this link (and use correct MCU software, yours is probably above 3.0) https://disk.yandex.ru/d/umCvHqCDzHccr/MCU for MTCD, MTCE, MTCP, Intel Sofia3g/CHS

P.S. I saw in one pic that you have superuser account enabled, how in the world did you get that enabled while just purchased it?

Can you backup this software of yours on a stick, transfer it to computer and upload it to me on google drive? cloud ?
[Android Head-Units] ramunsa:
Thanks a lot for the guidance on which software to pick. Is there anywhere a write up the difference in Chinese roms vs clean rom's?

I did not do much to the rom, other than was trying to back it up via the laptop connected to USB cable using flash_tool. But no matter what I did laptop was not able to see the stereo. After 2 days I gave up.

I sure can back the software up just give me guidance on how to do it.
[Android Head-Units] Anton TNT:
I havent tried it yet with my device, but think that there is a way to transfer backup in hidden menu (8888). There is backup option, I saw it on my device, but havent tried it.

I dont know if exist a clean ROM, usually software is chinese branded so I dont know if it is any difference.
[Android Head-Units] ramunsa:
I will take a look if I can find the backup option. Is it under Car infotainment system (as in attached picture) or somewhere else?
[Android Head-Units] Anton TNT:
Just got into hidden menu you must go at MP MODE inside and copy settings into sd card or thru USB connection.

See afterwards if copied succesfully.

If not there , try with google cloud or disk it is in infotainment section /accounts/

P.S. I will check where is some kind of backup and if other solutions are possible on my device, as we have similar software.
[Android Head-Units] ramunsa:
how do I get to "Just got into hidden menu you must go at MP MODE inside"?
[Android Head-Units] Anton TNT:
at infotainment where mcu and other settings are click on icon wheel/settings and enter pin 8888, once inside go to MP MODE ...
[Android Head-Units] ramunsa:
here is the link for settings backup

ts8227Lfactory.bin

drive.google.com
[Android Head-Units] Anton TNT:
Thank you and on behalf of other users in need. This may help them.
[Android Head-Units] ramunsa:
I hope they find it useful.

I am still afraid to update my stereo without having a backup. No matter what I do flash tool does not see my stereo. Most of the videos shows to short 2 pins on the motherboard, but my motherboard does not have any :(
[Android Head-Units] Anton TNT:
There must be a way there is on aliexpress lots of cables for that if you know how to look for it
[Android Head-Units] ramunsa:
here is a picture of my motherboard. all the cables connect to the top right side. There is an open 4 pin connector. Could that be for the USB that would be able to read flash? there is also another similar connector. What about test pads. can anyone spot them? What is the name for that 4 pin connector?
[Android Head-Units] Anton TNT:
You can only get it from seller... also there is similar zip file for import at 4pda Russian forum, I don't remember where it is, I cannot find it, but you should search for it there if seller doesn't respond.
[Android Head-Units] MierdaAutorradio20:
Hello, the seller does not send me those files for the buttons. I have only gotten a firmware update that does not solve the problem. ☹️😡 What Russian forum are you talking about? The one that appears in this forum? Thank you
[Android Head-Units] MierdaAutorradio20:
I can't find anything on the 4pda Russian forum. ☹️
[Android Head-Units] Anton TNT:
I have those files for import but probably when you import it it won't work because buttons are on wrong places on unit. Will try to find you a match ... and by the way your seller must have those files or ask their technicians / providers of units for it.
[Android Head-Units] MierdaAutorradio20:
Thank you so much! I have asked the seller and he says he has nothing more than a firmware update file. And I have insisted that he get them from the factory or tell me where, but nothing. Would the files provided by Arcarco work to do what I need or would they be incompatible?
[Android Head-Units] arcatarc:
Ok....try this way:

Ok...try this way:

Go in Settings-Car Infotainment-About Device and in menu insert 5555 code (not 8888)) put an empty Sd on the HU and save your actual configuration (to keept as backup) to sd then remove the created file from it and save on your pc.

Now put the ts8227Lfactory.bin i provided you in this post (it should have the same name of the one you created) on the sd,and click Import, then reboot.

NOTE; If backup process don't work i higly reccomend to take screenshos of all submenu so that you can reinsert yours previous values because this process will raplace all them with those from mine.

When you finish remove file from sd or it will continue rostore every reboot.
[Android Head-Units] MierdaAutorradio20:
Thank you very much, but it doesn't work. Reactivate only the volume knobs and move forward. But remove the volume, the other buttons do not work and change the language to Italian. At least we confirmed that I need the correct button file. Thank you so much.
[Android Head-Units] arcatarc:
Ok...last chance is to contact your reseller and ask him if he can send you the backup obtained from the 5555 menu from an identical HU.
[Android Head-Units] MierdaAutorradio20:
I have already tried that and I have asked the seller again, but he says he does not have those files. Let's see if our colleague ANTON TNT can get it. It would be fantastic.
[Android Head-Units] arcatarc:
If your reseller don't have this file he can create one by using the 5555 code from an identical HU...
[Android Head-Units] MierdaAutorradio20:
If anyone on this forum has the same model and can give me a copy of the file, that would be great. Thanks for everything.
[Android Head-Units] Anton TNT:
Please share a picture of your buttons knobs...
[Android Head-Units] Anton TNT:
https://drive.google.com/file/d/1Z8oJnaxya2ATl2WR7jKCcoMP4mzmyyVG/view?usp=drive_link

This link above corresponds for ALPS FF5000 units with 8227L chipset, it may work but buttons will probably be in incorrect places (like NAVI will be HOME etc., Volume knob will be the same)

Here is image of default unit (my old one from y2020 - ALPS FF5000) with physical buttons visible, most likely it will set buttons like that.

HOW TO INSTALL those downloadded key files: unzip and transfer files to a blank USB drive and put it in port of unit, then click on IMPORT button on upper right, next to SAVE button, on menu KEY in factory settings.
[Android Head-Units] Anton TNT:
Also to mention those 4 files inside can be edited and tweaked to match any 8227L unit buttons.

Download program for opening .bin files and tweak configuration buttons if buttons or volume knobs are having incorrect functions.

See this program for program editing .bin files... https://www.ultraedit.com/products/...aj3-MF95gafvW8mtO7wiDqgMKo4vwbIkaAnvgEALw_wcB
[Android Head-Units] MierdaAutorradio20:
This is the picture of my buttons:
[Android Head-Units] MierdaAutorradio20:
What a pity! The buttons will not match. Thank you so much.
[Android Head-Units] MierdaAutorradio20:
Thank you very much for the information and help. But I don't think I would know how to modify the file to make it work.☹️
[Android Head-Units] MierdaAutorradio20:
This is the exported file from my android radio with the buttons issue. I'm uploading it here, in case it helps to edit it and fix it so that the buttons work, please.
[Android Head-Units] Anton TNT:
I can't do much with this ts factory bin file it does not contain any of the button files. Correct procedure next would be that you obtain it somehow thru alps device manufacturers , contact them and explain situation and do send them this front side pic of your unit.

Website is https://www.alpsalpine.com/e/common/inquiry/

P.S. you can try also obtain a clean copy of a original ROM installed on your unit, but low chance is that the seller will give you one. You must search this forum and contact some expirienced people that have done rooting / ROM erasing and then install with help of proffessionals original software firmware that was on this unit.
[Android Head-Units] MierdaAutorradio20:
Hello, what a pity that the file I uploaded is of no use. I have contacted a member of the forum who seems to have a radio similar to mine and they can send me the file for the buttons. But I still haven't received a response. Thank you very much for all the help and your advice. I will try contacting the Alps device manufacturers to see if there is any luck. Getting a clean copy of my unit's ROM from the seller is going to be impossible. With how easy the solution is, and how difficult it is to find the right files...☹️Thank you very much for your help. I hope I can solve it somehow.🤞

they have not helped me and the seller insists only on sending me a firmware update. I also can't find anyone who still has the same radio as me who can help me with a copy of its settings. Such a simple thing and so difficult to find.☹️☹️
[Android Head-Units] cr4ck3dn:
Hi friend,. I'm sorry if you have this problem. If I found somewhere an device same as yours I will tell you.

Have you tried the normal 4 keys import file?

Extract all 4 bin files to flash drive then go to 8888 menu , keys and click button to import keys. Try it.

You can download the file here:

keys.zip

keys.zip

View and download from Yandex Disk

disk.yandex.com

Tell to your seller to send you update file then send me link to check.
[Android Head-Units] MierdaAutorradio20:
Hello, thank you very much for your help. It would be great if you find a device like mine. 🤞🤞I have not tried the files you tell me, my device has more than 4 buttons. I can try it to see if it helps. My seller's update is this:

https://www.dropbox.com/s/jdkw3jru5id4ujn/Firmware 4 core.zip?dl=0

Greetings and thank you very much.
[Android Head-Units] MierdaAutorradio20:
Hello, I have tried the normal 4-key import file and some keys work with a different function than the original and others do nothing. It's something. The truth is that the problem would be solved with the correct files.

Thanks you.
[Android Head-Units] MierdaAutorradio20:
I have tested these files and they make some buttons work with different functions than the original ones. No idea about modifying the function with the program.
[Android Head-Units] Anton TNT:
you can try learning the buttons with touch study menu in factory settings, it might set up correctly some buttons
[Android Head-Units] MierdaAutorradio20:
I will try it, thanks.
[Android Head-Units] MierdaAutorradio20:
Unfortunately, it doesn't work. Touch study does nothing.
