@surfer63 Thanks for all of your work! This is great!

Maybe now I can downgrade carlink or figure out a way to change the resolution because with the latest Joying update Carlink 2.0 is HUGE with android auto, it's stuck in 480p and I have the 1920 x 1200 screen.
[FYT Android Head Units] surfer63:
The 6GB is indeed a setting also in the specsheet. I never understood that with 64bit chips. I know that the theoretical 16.8 million terabytes can't be used as we are currently limited to 8 terabytes due to cache and bus limits, but these units should easily address 8-16GB. I assume it was simply a builtin limit as they are actually for light embedded devices. How will you ever put so much memory in a phone, unit or even pc.

The 7862C is the latest version. Maybe that one is now limited to 8GB instead of 6GB
[FYT Android Head Units] surfer63:
I updated post 2 (More about Firmware(s) and added a paragraph VIII: Flashing a Full firmware, an AllAppUpdate.bin or a new system/kernel/core from another reseller

In case of unclarities let me know.
[FYT Android Head Units] surfer63:
I haven't looked at the carlink app (why use Android auto if you have a full fledged unit in your car), but this sounds like they forgot to pack the hdpi resources into the app.

(Or they think: Which ***** uses Android Auto on one of these great full fledged 1900x1200 units? We will not even add the hdpi resources for such a unit ;) . Using Android Auto in such a unit is like building a very old fm/am radio into a very expensive Tesla, Mercedes Maybach, BMW, etcetera)
[FYT Android Head Units] DreadfulDrummer:
Wouldn't the resources be on the phone running Android Auto, not on the head unit running the receiver app. Said app would have to report the display resolution to accurately present the projection from the phone. And the main reason people would use Android Auto is because the interface is designed for safe use while driving and "glanceability" which the tablet layouts for apps like Maps and YouTube Music just don't provide. (The AA apps could do a helluva lot better, mind you)

Another reason might be they just think it looks pretty 😅

Or perhaps they like to continue their music in their headphones once they've parked up and want minimal interruption in the soundtrack to their life, which is there to keep the demons and intrusive thoughts at bay. Maybe they have tinnitus like Baby Driver... My point is you never know with people. 😌
[FYT Android Head Units] surfer63:
I like your comments :)

Coming back to the above: The previous version displayed correctly.

And having AA perform so badly would immediately have resulted in a storm of AA bugs.

I therefore think it is the carlink 2 app. Somehow it is not reporting something correctly. And I agree with you: it is more logical to expect it doesn't report correctly to AA then that it's hdpi/xhdpi/xxhdpi resources are missing.
[FYT Android Head Units] DreadfulDrummer:
Hey man,

I'm just making my way through the OP. Loving all the info (even if it is a bit of an overload of such 😁 you always provide, my dude) particularly the link to Mekede's firmwares. I've had no luck getting the seller to cooperate and send me even the currently installed firmware on my unit. However, I have a K200S, for which there doesn't seem to be any firmware. The page advertises a K-series unit up top, with the knobs below the capacitive buttons either side, but there appears to be no downloads for these units. It seems the M200S runs identical software but I don't want to flash the wrong stuff and gimp my knobs 😏

All I'm really looking to do for the moment is change sys.fyt.bluetooth_type

Can this be done without the firmware?

Cheers🤙
[FYT Android Head Units] DreadfulDrummer:
I've just seen your instructions on where config.txt is located on the device 🙄

I'd always thought it had to be extracted from the firmware! So a simple script could be made to change that 1 to a 0, right?

Any help achieving that would be appreciated, if I could be pointed in the right direction (never made such a script before)

Thanks again, @surfer63 🤙
[FYT Android Head Units] DreadfulDrummer:
Alright, last one, I swear! 😊

My unit is uis8581a2h10. Do I need a different binary?

I've found your Replace_configtxt.zip which contains three different binaries and three different scripts, one of which is 8581lsec.sh so I'm guessing I could use that.

Is /storage/sdcard1 in that script referencing the USB drive on which the modified config.txt and binary would be placed or should I modify that?

Sorry for all the questions (but hey, that's why we're all here, right?)

Also, I'm in New Zealand so apologies if you wake up in the morning inundated with DumbandDummer replied/mentioned/quoted you notifications. I'm trying! 😅

Thanks again
[FYT Android Head Units] surfer63:
That was a very short brain disfunction.

You can flash a new config.txt to your unit by only copying that config.txt and, in your case, the lsec6316update binary onto a clean USB-stick. That is enough.

See my newly added Q17 in the post #1 Q&A about the binaries and scripts. And I mentioned flashing the config.txt in post #2 VIII.
[FYT Android Head Units] DreadfulDrummer:
D'oh! Completely missed that handy table in Q17. Good stuff; well organized. I just got excited and tripped up on all the new incoming knowledge.

So only the lsec6316update and config.txt? No need for 8581lsec.sh?

Hi Everyone,

I bought my first android head unit in my life, which is Mekede M300S type 3/32 9 inch with Car-link 21.0910.1741 I only want to update the system (as I read there should be Dec update, my unit is on Sep system) of the unit with the files that are available here and add in some lines into config.txt:

#for mic boost
persist.sys.zlink.mic.vol=9.9
persist.audio.mic.senstivity=1
persist.btmic.gain=10
persist.btspk.gain=7

#should fix native wireless aa support and recognize bluetooth obd2 device.
sys.fyt.bluetooth_type=0

I have been reading and following the topic for a few days, I may come up with some questions about doing this.

Thanks in advance.

edit: I can not download the files from the website as I can not sign up: "Can not complete as account is limited. Please do not retry." If someone has the update it would be appreciated to upload it somewhere.

edit 2: is this package compatible with my unit?
[FYT Android Head Units] nagibo77:
Hi friend very very good work thank you very much.

my question when I try to Buckup the unit give me this message ( 8G DDR ! use Isecxxxupdate file after 21-09-2021 ! ) as in photo attached my unit as in photo2 attached

could you help me please .
[FYT Android Head Units] hanichl:
Hi, its your turn to get the right package for the right unit on your own.

problems with downloads from manufacturers websites are also not concerned here.

compatibility of packages has to be checked by the downloader ....

first download your right package and install / update native STOCK firmware.

then you can go on with fiddling and modifying the firmware.

good luck

[FYT Android Head Units] roti86:
Yes, okay. I managed to update. I installed this , thanks to @surfer63. First I did a backup by using his script, then I installed the new files, but before that I modified config.txt with notepad and put the values that I needed and wireless android auto also works with updated carlink. I have not installed the unit to the car, I am waiting for the frame and proper cable, but hopefully bluetooth calls with external mic will be better and unit will be compatible with my bluetooth obd2 dongle.

Hi all.

Has any way been discovered to run a "normal" BT stack on these units so i can connect to bluetooth GPS for example?

Would happily sacrifice the phone integration.
[FYT Android Head Units] marchnz:
No. However no issues pairing BLE devices such as a radar detector on my type 116 (sold by mekede)
[FYT Android Head Units] farhanito:
Within UIStyle i used (forgot which number) there's an app/shortcut icon named "BT-2" which launched 'standard' android Bluetooth setting. I can pair my Bluetooth remote buttons through it. I think it runs independently besides Bluetooth phone connection.

There's also a mod app/shortcut that will launch standard android settings. Try it.

Like this one from @mariodantas
[FYT Android Head Units] stealthee:
When I press the power button on my Mekede 7862 it just turns off the screen. II would like it to shut off the screen and the radio maybe show the date and time. But id settle for a shut-off radio like any normal radio would do when you press the power button on the volume knob.
[FYT Android Head Units] Kwen:
Btw, in order to support 8GB of RAM, you need to use a newer lsecXXXXupdate, the backup script wouldn't run otherwise.

I have installed latest kernel 2022-04-07, any issues if I also flash the AllUpdate.bin from Joying on an EKIY (FTY ID=1)?

[FYT Android Head Units] homarci:
Hi All,

I have a UIS7862 head unit with Raise FORD-RZ-09 canbus adapter.

I believe the wire loom i received is incorrect - could you please help if my assumption is correct?

Attaching the current wiring. ACC and reverse detection cables were removed as suggested by the seller and connected directly.

Canbus box documentation - based on this I believe I should add CAN_L and CAN_H connecting to Quadlock's A11 and A9 pins. Also as I see the current wiring, I should move the white cable from Pin14 to Pin16 at the canbus box. (The two with cables at P13-P14 currently are connected to the canbus port of the head unit)

Currently I am missing functionalities (e.g. climate control, door open notification, compatibility with the car's built in screen), buttons working fine on the steering wheel - this why I started to check. Also reached out to Raise and the seller of the head unit but no meaningful update so far.

Thank you

[FYT Android Head Units] surfer63:
@mariodantas delivers a kernel, not a complete firmware. So the application layer with the canbus software has not changed. Theoretically mario's kernel should not do anything (!) to the app layer.

The only thing I can suggest is to look again to your CANbus settings.
[FYT Android Head Units] surfer63:
Search !!

You did not even look one page back (19 posts back) where another user asks exactly the same question.

[FYT Android Head Units] surfer63:
I see. You have an empty 360res folder and inside the aw360D folder everything that Mekedes have inside the 360res folder.

I just rewrote the script to make it an all purpose script. It functions but still gives an error message. I do not understand yet why.

Please try it and let me know the listing from the AllAppUpdate.bin.

Hi guys

today, i forgot to put on the windscreen sun shade, so I thought i should measure the CPU temperature using Aida64. I was shocked when i started the car at 1 p.m. to find that the CPU temperature was 100° at the start and then it dropped over the minutes (thanks to the fan i presume).

Is 100° a real value!!! What are you using as a measurement app?

Do I risk anything if i forget next time to put on the sunshade when the car stops knowing that the city where i live experiences very high temperatures during the summer and which are around 50°
[FYT Android Head Units] surfer63:
It is definitely not good, but not terribly bad.

If the CPU gets too hot, it will throttle down and eventually switch itself off to prevent damage.
[FYT Android Head Units] AviationPhotographer:
I've got a weird one. On my Toyota Prius (2013, base model, stock), I have the Canbus hooked up and the steering wheel functions work great except one thing... the volume up and down buttons are reversed. So pushing the volume up turns the volume down. I've tried to change the vehicle and Canbus style to all sorts of different Prius ones, but no matter what I choose that works with my Canbus, the volume buttons are still swapped. Any ideas on how to switch them around?
[FYT Android Head Units] Renval:
go to settings, factory, look for "volume inversion". You can swap the volume keys there

Thanks for checking on this. These files are symbolic links. 7zip can't deal with symbolic links. You can force-zip them, but they will be restored as normal files, not as links.

I did not add the logging option as users mostly provide a simple screenshot.

Maybe I should still add it, and maybe I should add a readme explaining that when these errors are encountered, it is not a problem.

Thanks anyway. It is always good to think it over again and maybe come to something better.

I need some help with my headunit...

Its got stuck in the boot loop, eventually showing a sideways error message, below:

I understand that I need to reinstall the firmware, but the seller isnt cooperative at all.

This is the one that I bought:

I've been reading this forum and as far as I understand, I should be able to flash over the 2023-05-09__FYT7862_FW_MD_EDITION_WITH_MAINSERVICE firmware (please confirm), but I dont have the 360 app.

Is there any suggestions on how to solve this? I have no idea what the manufacturer ID is...
[FYT Android Head Units] Battoussai:
Hi there.

Does your unit have a RESET hole? Usually is at the front of the screen.
[FYT Android Head Units] danielsdian:
Yes, its an RST button

I tried pressing it, it just boots the unit again
[FYT Android Head Units] surfer63:
What did you do? Did you flash some firmware? And from which reseller?

Or did it just start doing this? That might mean a faulty emmc disk. So how old is it and can you get a refund?

Please first answer these questions before you think of doing below.

I don't think the mario dantas kernel is useful in this case, as your error shows that it boots normally, but doesn't have an application layer to continue.

So either you flashed something incomplete, or your unit is malfunctioning.

If you want to flash it, and you don't get support from your reseller just take a 2000x1200 firmware from Mekede, with or without 360. That doesn't matter. If you don't have the 360chip built in to your unit, it is just another apk with libraries that can't be used on your unit.
[FYT Android Head Units] danielsdian:
The unit was shutting down randomly after some time and wouldnt turn back on.

I pressed the RST button while trying to diagnose if it was an wiring issue on the car installation and everything went kaboom.

Its quite new, but Im after the refund period on Aliexpress, however the seller says that there is a 1 year warranty.

This is the listing I got it from:

https://pt.aliexpress.com/item/1005004380873669.html?spm=a2g0o.order_list.order_list_main.17.58a7caa4AbUof6&gatewayAdapt=glo2bra

The 360 cameras plug directly into the unit, I think the chip is built in, with no additional dongle. Its not USB.

The DVR camera is USB.

Do I just go ahead with the Mekede software?

Is there any way to regain the use of the 360 cameras after?

Here is the single piece of instructions that I got with the unit:
[FYT Android Head Units] surfer63:
I forgot one step: Your system is still bootable, so please first try my getinfo script. So not the HWGetInfo.apk, as you can't fully start your unit, but the getinfo script. It is the second but last script in post #1 of the "General FYT based Spreadtrum uis7862 (unisoc ums512) - Q&A, Mods, tips, firmware" thread.

Unzip it so a clean FAT32 formatted USB-stick and use it to "flash" your unit.

As your unit boots, but is somewhere stuck, we need to first get all the info we can get: manufacturer id, bluetooth id, corrupt or not /oem partition, no launchers anymore, etc..

The script will save the info on your usb-stick in folder "FYTget_info" and in a compressed tar file named "FYTget_info.tgz".

Please share that. It does not contain any private info at all. And if you don't trust me ;), send it to me as PM.

If that doesn't work we need to blindly flash a Mekede firmware with 360 and for 2000x1200, but please wait with that.
[FYT Android Head Units] danielsdian:
Im attaching the TGZ file here...

The unit managed to boot after I ran the script, but I dont think its stable at all. Can I do anything to get any more info from it?
[FYT Android Head Units] surfer63:
The tgz looks absolutely normal.

The one thing I forgot is that the fytmanufacturer and sys.fyt.bluetooth_type are set when the unit is active. The getinfo script can't do that, but needs to copy a few files to include the info. I never needed that before.

I just added that to the script and uploaded a new version.

To get to know this, and be able to reflash your unit as stable as possible, if you want to, I need to ask you to download the new script and run it again. The new script will also copy the fyt.prop, fyt_build.prop, config.txt and Ver file into the tgz.
[FYT Android Head Units] danielsdian:
Something is wrong with the headunit. Now the screen wont show anything, is just black.

I tried disconnecting the battery of the car, still nothing.
