it runs ok but lacks some common car brands/models, and it has many "dlc" purchase options to unlock its full potential
i have found on youtube someone showing this device rooted unlocked and able to run any software, but absolutely zero details on how he managed to do it.
video here :
i would like to try the same to test to run other obd software, like torque for example hoping it is more "complete" for my use here in france with local car brands
so far i get it runs on android (version?) , it has a usb3 port, wifi (i managed to get the mucar update OTA) and a sdcard reader and a file explorer, where i can see and launch an apk from the sdcard but the apk install auto close automatically and it send me back to the original device interface.
can someone coach me on what to do /what to try please ?

I dunno. I'd rather lose the device and use either a OBD-II/Bluetooth or OBD-II/USB adapter and a stock Android device.
Me? My vehicle is 28 years old and uses OBD-I (a/k/a ALDL)
I use my own µC to go from OBD-I to USB and I have a custom Android app.
In another decade I might own a vehicle with OBD-II.
thank you oswald. sorry for not posting in the good place, i thought "hacking" was appropriate.
renate : i understand what you say : less trouble getting it to work. but since there is a video showing it is possible with my device, i want to try, if i can get a little help here.
anyone : some hints ? should i treat it like a locked tablet ? what are the methods - steps to investigate ?
edit : some info found online :
Android system: 6.0
Running memory: 2G
Storage memory: 16G
Screen size: 4 inch IPS (480×800)
CPU: MT6580 CORTEX-A7 1.3GHz 4 cores
can this point me towards some unlocking/rooting methods ?
Me, I'd see if there is a UART running console inside there.
Is ADB enabled?
I'm all for hacking/rooting a device for all access, but if they have paid tiers I wouldn't hack that.
By the same token, I wouldn't buy a Kindle with ads then defeat the ads.
OTOH, I wouldn't buy a Kindle anyway.

Can anyone please tell me how can to fix the fake google play protection warning shown in the apk while installing the app.
I have tried signing the app with android debug key and also i have tried signing the apk with my private key(whose apk is present in playstore) but still i used to get this warning.
I dont want to disable the play protect(as this is not the solution)
PS: when i make clones of the same apk for eg making 10 clones of 1same apk and every apk with new unique package name out of those 10 clone i used to see the play protect warning in only 4-5apks and rest apks used to be good (its not the issue of the package name)
Everything was working good but i started facing this issue of google play protect warning since Nov2021.
I have also tried to sign the apk with apkeasytool but still the same issue.
IT WILL BE BIG HELP FOR ME TO IF SOMEONE WILL FINDOUT SOME WAY TO FIX THIS PROBLEM

Hey, noob developer here. I'm trying to make an app as a privileged module because I need to access a few files on the device that I can't access using a normal app (with no privileges and permissions). I have an android.mk (its located at {packagename}\app\src\main) with the command LOCAL_PRIVILEGED_MODULE := true in it. I'm not sure how to include that into my gradle.build file so that I take in that command and hopefully spits an apk which is a privileged module. I'm using Android Studio Chipmunk (2021.2.1).
I'm sorry if i missed any details, I have recently started developing android applications so I don't have a lot of knowledge and experience, please ask any clarification questions and I'll try my best to simplify my problem for you to understand.
EDIT: I did a bit more research and added this to my gradle.build file

the code builds successfully but i still havent been able to access files in the /data/ folder. Any help would be greatly appreciated. TIA!

Sorry for my english.
Hello
I have a problem
I have had my phone for 11 months
after half a year it started to reset
application windows sometimes extend beyond the outline of the screen
gestures started to fail, I can't exit any application only reverting to the desktop
I already reset the device
and hence the question:
how to install ui 3.0 from scratch or custom firmware, if you have anything please reply

Hello,
I've got all the ROM from sp flash tools, when I repack the folder where I unpacked everything gets a smaller size than the system.img file, when I repack, I also get a smaller size even that I use make_ext4fs with the correct size.
So when I flash the system.img the phone goes straight to bootloader and doesn't boot.
How can I fix this?
Also, I want to add system apps to the system.img, how can I do that?

Hi there! I am trying to learn the same thing as well! I feel down the rabbit hole a year ago trying to get "tools" to work, and was not successful, maybe someone can teach us.
I can however, share with you a theory of different way of doing what we are trying to do that might? work for you? Depends if you have working firmware or not.
If you are able to flash your firmware and then preinstall your apps, you can pull the partitions.
It seems not all the partitions are the same on each device, so you would have to poke around to figure out what all is what.
running command df - h in adb shell can give you some clues. If you are able to install magisk and watch it in twrp, it can give you another clue about your boot.img partition.
I have all the commands and stuff I worked out in this comment as well as what I have tried and worked out. Maybe this can work for us!
Just note your mmc blocks- what they actually are- is likely different than mine
Also maybe someone can elaborate more, I just learned how to do this yesterday and it worked for me to not bootloop with the modded boot.img, just trying to find the right partition for my system now.
Thanks for your answer, I'm gonna try that, but I can't get the new system.img to boot on the device, I'm using a basic device that doesn't have TWRP.
Also, when I flash the edited system.img the device doesn't boot, I think its because of the size, any clue to fix that?
I know there is a command with it, one of the tool kits that carries the individual exe or bins whatever os you are running had it in there but I cannot think what it was but it could capture the original file size and amend the new one, I remember manually doing it by hand and not with a all in one tool. Your line of thinking is right, maybe check out some of the old toolsets on here. That is likely where I found it.

It was something like this, I tried running these in cmd and reading their help files but I didn't see what I was looking for, but some toolset like this on this site has the exe or bin (if linux) you need
I used make_ext4fs but I'm still getting smaller size
I got a TomTom go 500 and i tired to install someting called "tomplayer" (didnt work), i put in an micro sd card then i fomated the sd card with "trips" it was an 8 gb microsd card i used a 128gb one for maps but that data is encripted, and i plugged it into my pc and then there was an folder called "android" and ".android-secure" android-secure was empty but in android there was "data" -> "com.tomtom.navkit" -> (empty), i wonder does the device run android and could you put something like lingage os on there the device is really secured down like you cant access the devices memory and it showes up as an network card in device maneger, i cant log on with filezilla ima include pictures here. the date is probably wrong becuase im indoors and there it cant get an gpssignal and
