Help Connect to ADB

[chaimtg]

I have an mp3 device running android os on it but there is no option to open developer options. when pressing build number nothing happens. when connecting it to ADB on a computer and typing ADB devices I'm getting a message
List of devices attached
0123456789ABCDEF offline

is there a way to connect this to ADB?

what device do you have? what android os is it on? without usb debugging enabled in developers option, you will not be able to communicate with adb. what exactly are you trying to do?

im trying to install and uninstall more apps via ADB

are these system apps? if so the device will need to be rooted......unless you are trying to do this https://www.xda-developers.com/uninstall-carrier-oem-bloatware-without-root-access/

if so, then you need usb debugging enabled. but your device does not have a developer's option to do this......so you are pretty much sh!t out of luck.......sorry

is there such a thing that there is no option to open developer options on an android device

Yes, that can be done. A manufacturer can chose to disable, or remove the developer options in their various builds of Android for their devices. And they can securely lock Android down completely, so it only does what they intended, and nothing else. Which is probably what they've done with this media player device.

Android is open source, so it can be built and customised in anyway one likes.

When android is used as the underlying platform for a specialised device (audio player, ebook reader) it's not unusual.

I've seen Android been used as the embedded OS on quite a few different devices, like treadmills in a gym, in-flight entertainment on Boeing 787s, information kiosks on trains, electronic whiteboards in classrooms, payphones, etc. Of course on applications like these, they don't want punters messing things up, by finding things like developer options on them.

So there is no way to flash a regular version of android on this device? Is it locked for good? There is nothing to go around this?

One thing, there's no such thing as a regular version of Android, as Android must be built to suit a device's exact hardware setup and configuration.

Your device seems have a very restricted and locked build of Android on it, that can only do what it came with. There are other Android media players, like Sony Walkmans, that are more similar to smart-phones, but without the phone part, that can install and remove apps no problems. I think the device you've got there, has more in common with those Jpay prison tablets, i.e. it's a very customised(lobotomised) version of Android on it, that has no way in or go around....

You get what you see, and that's it.



Android is distributed as the AOSP(Android Open Source Project). The hardware manufacturers take the AOSP code to build and customise it for their devices and requirements, whether they be phones, tablets, media players, smart-TVs, electronic whiteboards, in-flight entertainments, kiosks, etc. etc. There's custom ROMs, but devs can only build those for the devices they have and know about, usually popular phones, like Samsung Galaxy or Google Pixel.
