Thanks for answer

Unfortunately I'm a very 0 on this matter.

Can you kindly explained me step by step how to do?

This script will permit to Google assistant to work fine?

And at last, existing a firmware mod, to permit to have an android without buyer locks on sinosmast 7862(s)?

Sorry for english
[FYT Android Head Units] faria:
Sure, it will be later when I get home, unless someone else takes over the task .😃

@papero1159

Goggle assistant will not works as it does in an android phone, the only thing you can do with it is ask questions as far as i know.

You will not be able to use it to launch any apps or commands like "play music etc,navigate home, launch youtube,etc"

This is not a problem with google assistant but one with Chinese units.

The reason it does not work is because android is just the platform that this manufacturers use to build their own custom layer on top ie (.allupdate.bin)

If you ask google assistant to increase volume it will ,but only the android Media volume, this does give the desired outcome because the unit only responds to fyt layer volume commands.
[FYT Android Head Units] surfer63:
"This script will permit to Google assistant to work fine?" if it is installed: yes, otherwide install it.

I have no idea what you mean with "And at last, existing a firmware mod, to permit to have an android without buyer locks on sinosmast 7862(s)?

Sorry for english"

Create a folder lsec_update.sh on your usb-stick.

Save the code from @faria in the file 7862lsec.sh inside that folder (if you are on Windows, use a good ascii-editor like notepad++, not notepad. And you might change the "desabled" in "disabled" ;) )

Copy the lsec6315update binary from your firmware in the root of that usb-stick (so not in that lsec_updatesh folder).

Nothing more!

Stick it in your unit and it will automatically reboot and remove (rename) the apks.
[FYT Android Head Units] papero1159:
Thanks Surfer63

I'll try. As asked before if you know a firmware for 7862(s) , without buyer locks and conf, that can directly installed I'll be very happy because will be most easy for me.

Thanks again

I'm little surprised because on the Dasaita installed on my wife car , googlle assistant perform call, open app, answer to questions as meteo etcccc...perhaps this "inconvenient" is linked to specific brand?
[FYT Android Head Units] Ragpuss:
Basically, what I am trying do do is to put together the very best firmware that I can, I have read a great deal on this terrific forum but I still have many gaps in my knowledge. I have flashed my head unit several times now trying different and updated kernels but there always seems to be a problem. One kernel will fix one thing but something else will then not work as expected, such as the volume mixing, satnavs, music and reversing beeps, I almost have it and then I check something else and BAM!! something else is not as good as it was before.

It would be great to just be able to build a full firmware update including all of the apps that I use for one effective and fully working system.

Members such as @faria , @mariodantas and @surfer63 all have been especially helpful, the write ups and how-to's are brilliant and have taught me a great deal, I just wish I had all of their knowledge myself, maybe one day, haha !!

I'm likely asking much to much from an Android setup but the closer to perfection that I can get the better :)

From studying this forum and the many great topics, I have learnt a lot about what I can do to build it but as my unit is a no name Chinese module made for a 2014 Jaguar XF I thought that another and better allappupdate.bin file might work better along side a new kernel, rooted and all of the other update files written as my Tesla style vertical head unit requires.

The main problem is with the files that I find they tend to be for the normal wide screen horizontal units so are 1280X720 or higher whereas mine is 600X1280 and I don't have enough knowledge to know if this will still work.

The other thing that I just cannot get to work is Google Assistant on the head unit. I have an iPhone so I would normally use CarPlay but I would really like to just have Google Assistant working for voice control on the actual herald unit for calls, music etc'.

Maybe I'm getting too old, (actually I am), lol but I have read everything that I can find on this and similar topics here and I still have problems in trying to put it all together in my head for the best working firmware.

Any further help would be very appreciated such as a step by step in selecting files for the full firmware flash following a complete wipe.

Thank you everyone for all of the help and information given so far.
[FYT Android Head Units] faria:
Welcome to the dark side! I know right!:ROFLMAO:

Thanks!

I for one actually love helping people here, as long they are genuine and diligent .

My background is windows Mobile, lol, and android but i stopped developing about 10 years ago hence my

title.

Most of my knowledge from those days are gone.

I do still compile my asus custom router firmare,(ASUSWRT)

I bough my device a few months ago and knew nothing about fyt but knew a bit about PX5 units.

I'm currently on version 23 of my custom room and this is only Allupdate.bin ,i haven't even decompile the kernel.

So far i can build the rom as i want like integrating updates,rooted bootloader,mods,add apps,remove useless stuff without breaking **** (that alone took 4 versions)

i can now also restore files etc while flashing a fresh rom.

my latest achievement is restoring all fyt settings automatically after a fresh flash, (this one is not ready for the public)

When it comes to apks im sh*t, cant make heads or tales of the smali crap, sure i can edit view but that's all.

I supposed the background knowledge helps but most of it Is from reading and a lot of trial and error.

I got give give credit to @surfer63, his writeups, they have started me off, thanks man!

Sometime i finish something a 10 pm and i go to the car to trie! OMG i need Help.:LOL:

I been thinking of writing a tutorial how to build a modest custom rom but so far i haven't got the time, there is allot to go over, perhaps around xmas, next week im away for 4 weeks doing a job for Toyota franchise and will be 7 days a week 12 hours a day.

Don't you just hate it when life gets between you and your toys:ROFLMAO:

As for getting old... :whistle::LOL:
[FYT Android Head Units] Ragpuss:
Lol, I'm glad I'm not the only one, haha
[FYT Android Head Units] faria:
I forgot the best part....

Awhile ago was struggling with a issue in my perfect rom at the time ( gestures kept being disabled)

Eventually i got it after a few iterations.

later that evening i pluged the usb drive into my laptop, the folowing day i went back to finish the rom, but the usb drive was not detected, upon close inspection a noticed the drive was bent! someone moved the laptop and banged it against something and broke it, i later found it was my daughter.:mad: (No touchie!)

5 minutes later and a soldering iron and i was back in business!

So i put another usb drive into the laptop to make a copy, this new drive required formatting, guess witch drive got formatted?! :sick::sick::sick::sick:o_O:eek:
[FYT Android Head Units] Ragpuss:
Sounds a lot like me and my two grandsons , lol, the amount of thumb drives, SD cards and SSDs I have had ruined from sticky fingers, orange juice and cordials spilled or wiped all over them just as I had them saved and finalised. All good fun though haha.
[FYT Android Head Units] surfer63:
Yes, We all have been in these circumstances once or more often.

Not so long agao on one of my first attempts to clone marios's work on the kernels, also something like that happened to me.

I work on linux and needed root access and did a listing of a folder from the root and decided I could empty the folder.

I did not do a "rm <folder>/*", but did a "rm *" and already wondered why it took so long. So I had an entirely empty partition.

**** happens.
[FYT Android Head Units] Gymnae:
I searched for this, but haven't found a related question or answer:

Are there apps or magisk modules which could mimick an OEM navigation system?

I have an head-up-display and a digital dashboard, which can display navigation hints, but only with the OEM nav unit. Which would've been 5k EUR extra and sucks. CarPlay or Android Auto are not able, at least in my car, to utilize these additional displays.

But since these head units and their hacked together firmware talk directly to the car, maybe there's a way to pretend being a built in nav system.
[FYT Android Head Units] Matt Devo:
your updated 1.1 backup script is broken -- the AllAppUpdate.bin it creates has all the files nested inside an 'oem' folder, which not only fails to restore properly, but also prevents the copying of the config.txt file (since the destination doesn't exist), leading to a very bad non-booting scenario. I'm surprised no one else has run across this.

It's also throwing a bunch of broken symlinks in the zip, AFAICT.
[FYT Android Head Units] surfer63:
Thanks for reporting. I tested it of course and had not seen this myself. I will immediately look into it this evening.

The broken symlinks is "by design". It should not follow the symlinks, but I will have a look at that too.
[FYT Android Head Units] Matt Devo:
to be more specific, the AllAppUpdate.bin created by the 1.1 script is an archive containing a single folder, oem, with everything in the /oem partition in it. When used with the updater script, everything is restored to /oem/oem/...

I unpack, strip, inject, and repack the file myself so I realized this pretty quickly :)
[FYT Android Head Units] surfer63:
I understand what you mean. I had completely overlooked the leading /oem folder and had not tested the restore.

I thought I could easily fix this by a "cd /oem" first and then zip the current folder, but it also tries to zip the entire /dev folder and because of the special structure in there (black devices, character devices, locks), zip crashes.

Hi, where you found the firmware? I search the sinosmart website for this but I not found. Can you explain how to receive the firmware?

Thanks
[FYT Android Head Units] rockman18:
Hello @papero1159, I have ask the seller directly on AliExpress for a new firmware. It is the lastest firmware available. I have requested for a new firmware last week but they don't have a newer version to share.

To update, download the zip from my link, extract the content to the root of a USB stick et put it in your FYT. The update will start automatically. Wait until the end.
[FYT Android Head Units] hanichl:
Settings in own apps will be deleted and other curiosities happen when /data/data is erased ( e.g. WiFi will be disabled, but the WiFi settings will remain).

Can AllAppUpdate.bin be modified to remove the erasing part ? Should this coding part be replaced wit hex00 or with '#' instead ?
[FYT Android Head Units] mariodantas:
You're right, with AllAppUpdate.bin, the data/data goes away (in fact wifi disables but acces point data untouched) like Android settings going away with update !
[FYT Android Head Units] hanichl:
Hi out there, has anyone succeeded in patching the AllAppUpdate.bin NOT to clear /data/data ??

Great rewards are promised for this heroic action, but will never be paid ;) :D
[FYT Android Head Units] mariodantas:
I think it all depends on the lsecXXXXupdate file when it detects the AllAppUpdate.bin file it formats /oem and maybe delete data/data because AllAppUpdate.bin is a bunch of apks and some settings (I didn't see nothing inside the files commanding a format of partitions)
[FYT Android Head Units] mariodantas:
A "crazy" idea will be "RE" lsecXXXXupdate and search for actions, modify then compile again, or looking with an HEX editor, but the file is maybe obfuscated (never took a lok with HEX editor in that file)
[FYT Android Head Units] mariodantas:
There's a rm -f /data/data inside the file

@surfer63 is it possible to you to take a look ?, I tried to modify "/data/data/*" by "/data/_ata/*" or by "/data/data/nothing" but.... as expected, the file does not boot at all, maybe signed ?
[FYT Android Head Units] surfer63:
I already did and found the same pattern and modified it. It doesn't work, like you experienced as well. I think it has an internal CRC check, like nowadays the CRC from the BlueTooth apk is checked as well by the system to prevent BT modifications.

And I think it is due to the dynamic partitions where FYT chooses (again) the simplest solution. Any AllAppUpdate.bin causes the entire partition to be rewritten, which is not necessary.

@gordgelin made a mod which uses the old partitioning. He compared a couple of the first firmware relases, which used the old partioning, with the newer firmwares, which use the dynamic partitions. A very nice job. That makes it possible to make partial 6315_1.zips and partial AllAppUpdate.bin flashes. This makes it also possible to use all twipe options.
[FYT Android Head Units] gordgelin:
it has nothing to do with AllAppUpdates.bin contents, if AllAppUpdates.bin present - lsec6315update wipes /data/data

you can not change lsec6315update that easy, it is protected image so it will stop working after you change anything
[FYT Android Head Units] mariodantas:
I saw that.

One day we have to meet someone working for FYT and get that damn source code LoL
[FYT Android Head Units] surfer63:
If you really want to be in control you make a modded ROM like @gordgelin did. It is a lot of work and not simple, but doable if you have the knowledge of the new and older firmwares. If you understand what I wrote in the first posts of this thread about the firmwares and look a bit beyond the standard (dynamic) partition structure, you can do it.
[FYT Android Head Units] mariodantas:
Too much work for an older Android version !

In my case there's nothing more to do with this FYT 7862 units, will leave it as-is, no more mods

Was looking into Android 12 for Raspberry Pi (I compiled the aosp for that) but this will be another thread in this forum as not FYT 7862 related
[FYT Android Head Units] surfer63:
You mean the Android 10 on a uis7862?

For me it is just too much work for my uis7862 unit. I am a very simple user (radio app, music player app and navigation) now using a nicely working Mekede. Why put all this time in it?
[FYT Android Head Units] hanichl:
BTW, did anyone look in the glass bowl and can say if there ever will be a stock firmware of any manufacturer with Android 11 ( for UIS 7862 ) ?¿¿??
[FYT Android Head Units] hanichl:
@surfer63 : may I ask which apps you use for the basic functions ?

I would say for radio : Navradio+ . Lets us know what you are using for music and nav.

-- so mine is Navradio+, Poweramp and Sygic.
[FYT Android Head Units] mariodantas:
Say only fakes (build.prop) Android 11, still API29 (10)
[FYT Android Head Units] mariodantas:
I use Magic Earth for offline maps, Poweramp for music and Navradio+ for radio
[FYT Android Head Units] surfer63:
In the first post I wrote where this thread was for:

This thread is NOT meant for:

buyers advice (is this one better than that one?)

4G providers, DAB+ modules or DAB+ software (see here for DAB-Z by @realzoulou), Navradio+ (see NavRadio+ ported to UIS7862-FYT devices by @KoTiX2 , sub-woofers, OEM cameras, OBD devices, TPMS or other peripheral devices.

ABSOLUTELY NOT for posts about "what is/are your favorite app(s)?"

I prefer to keep it that way as it is such a personal question of taste, even though I unintentionally might have hinted for users to mention their favorite apps in post #331 when I mentioned that I am a basic user.

[FYT Android Head Units] yokala:
I might have briefly talked about this a few years ago but maybe it can interest the 3 or 4 people in the world like me who have the 11,6 inch Joying unit mounted permanently in vertical position.

I've always find the stock UI for the reverse camera is ugly AF and such a waste of screen space as it uses only a third of the screen to display the video feed of the camera.

I came out with a dirty alternative for that. The goal here is to have a better UI for this, and as I always use split screen mode, I wanted to use this feature when needed.

It cost me less than 20€, some hardware and software hack but I think it's worth it.

The parts :

AHD camera (6€ on Aliexpress)

HDMI capture card (5€ on Aliexpress)

BNC to HDMI converter (6€ on Aliexpress)

RCA to BNC adapter (1€ on Aliexpress)

small USB extension cable

automotive relay

(You can even make it much cheaper and simpler if you don't absolutely want an AHD camera, in that case you'll only need a standard camera, an RCA capture card, the USB extension cable and the relay)

Camera --> RCA to BNC --> BNC to HDMI --> HDMI capture card --> USB extension hacked with the relay --> HeadUnit.

AHD capture card seems to exist but it's quite expensive (around 45€) and I haven't tested it, it might work.

I used the relay with the reverse trigger 12V to close the circuit on the red wire inside the USB extension cable, so the capture card would be connected to the unit only when the reverse gear is on.

On the software side, I use the app USB camera (you can use the free version, but I use the paid)

A few firmware ago, when a USB device was plugged in to the unit, there was the traditional android popup asking to authorize the device and what app to run with this specific device and it was just perfect, you only had to select the USB Camera app, check 'remember my choice' and you were good to go.

Unfortunately, this doesn't work anymore, the popup is missing now so the unit doesn't do anything when the capture card is plugged in. To fix that, I used the app Automate from Llamalab and I'm rooted.

I've created a very simple flow with 2 bricks, a 'file monitor' witch looks if a file is created in the directory '/dev/bus/usb/001' and a App launch brick.

When the capture card is plugged in, a new file is created by android in this directory, so the app in ran.

Of course it's a crappy solution and it works well for me because I don't use any other USB devices on my unit.

Of course it will run the app on whatever device you plug in (the name of the file is a number and it's incremented every time a device is plugged in so it can't be predicted, that's why I'm looking for any new file created).

BTW, if someone more clever than me have a better solution, I'll take it :)

But in the end, I think it's much better than the stock UI because it's a regular app, it doesn't take over android and you can do whatever you want with it : close it, use it in split screen, etc.

Now, has anyone had experience with such headunit? It is Kunfine brand, 64/4 gb model, this radio module is one I see first time so idk how will radio reception be. Sound processor is good I assume? Eyeing this unit specificaly because of lower price + supporting showing data on MFD and dynaudio OEM amplifier, for 160euros I think I can't make mistake, but I already changed few headunits and none had supported those 2 features.
