Hi guys, i have a problem with unknown devices.

I have 2 same ROOTED devices, so i was trying to change /system/build.prop and i didnt have permission, so I was trying so much things and i got device that wont boot :)

Device is custom tv, very unusual, android board model is ad500a , cant find informations about it on net.

So, when i power on device, it only shows boot image, my pc doesnt see it, adb devices shows nothing.

Is there any way to clone or whatever nand from the same device? I have .ab file from it.

Thank you so much

Never heard of a .ab file, so no idea whether that helps.

If you have a custom recovery on both you might be able to back up one and restore the backup on the other. But for something as obscure as this I guess you probably don't have a custom recovery - they need to be built for the particular model, so it's unlikely that anyone has built one for a niche device.
 
So unless your ROM building skills are up to the job, you have a brick on your hands.

Maybe possible, if you got the correct technical information and tools required. But if there's nothing on the net, and nobody knows about this particular "custom TV"....good luck with that!

Was it bought cheap online from China or something?
 
What kind of technical infos i need? I have one correct device, and one broken.

There should be a download or fastboot mode you can access from the bootloader. If you had the official firmware and whatever flashing tool this device uses you could reflash the device, but you say you can find no information.

What exactly is the ".ab" file you mentioned?

Otherwise, if you cannot communicate with it how could you copy files to it? Fastboot cannot be used for that, only for flashing images to partitions (or erasing them), so you would need the images to do anything.

Well you basically need the manufacturer's information and any of their tools that might be required. But if it's bricked and unresponsive to USB connections, it might need the manufacturer's JTAG rig. But we don't know anything about who made the thing.
 
There is a reset button, but when i press it, display only turn off and turn on, no usb notification on my pc.

I got .ab file with adb shell backup.

Thanks

Ah, ADB backup. That probably won't have backed up the system files, and anyway you need to have an ADB daemon running on the device to use that, which means you need to be able to boot android on it. So I'm afraid that won't help you.

Absolutely no technical information for that whatsoever. "Actions" is only referring to the processor manufacturer, Zhuhai Actions Semiconductor Co. Ltd.

Many of the Shenzhen backstreet companies who actually put these things together tend to be very anonymous, often no websites or anything. And only advertise their business in a local Chinese trade newspaper.
