no devices/emulators found

Hi

Sorry for what is probably a stupid question, but adb returns error: no devices/emulators found - where can I find the drivers for windows 10 for this tablet?

Thanks for the help

Edit: Never mind - found how to enable USB Debugging.

@said2200, you need to install something to disable dm-verity. You said you rooted it, but it doesn't seem that you have. You only have temporary root. Installing Magisk will disable dm-verity.

Any chance we can get an unofficial ROM Port? This thing with lineage oreo or pie would be incredible? I do not have the technical prowess, but is there any way I can help with that development?

You have it installed in your patched boot image, but not on your internal storage boot partition. That's what I mean by temporary root. It's not booting because you have modified some files in /system and now it's failing the integrity checks. You have to use Magisk Manager, under temporary root, to install the zip directly to your device.

So you don't want root anymore? To get back to stock:
  1. Reinstall the firmware zip package through either the stock recovery or TWRP.
  2. Boot to temporary root and run the unlock tool again and select the lock bootloader option.

Here is my story. I had successfully done the root. But after the last update, normal boot always stuck at ASUS logo. I have to boot from the laptop using fastboot and patched boot file.

What options I have to go back and unroot? Since there is no custom firmware available, I prefer to go back to the original state.
Unlike Google products, I don't see an image available for this tablet to go back to the factory.

Guys, if your tablet is able to do tethered boot with a patched image, but unable to boot on its own, the fix is very simple. Just open Magisk Manager under temporary root. There will be an option to install root to internal storage. Use that. This only applies to unlocked bootloader.

If you don't want root, then boot to recovery (with 'adb reboot recovery' for example). Fiddle with the keys at the android image to get to the menu. Install a factory zip package that you have put on the SD card. Done.

So the official unlock tool is just gray and wont let me press it.

Do i need to disable lock screen\encryption or something first?

edit: you need to scroll the text down to the bottom.. I did not even see that the text was scrollable...

    Tool to Unlock Bootloader in ASUS ZenPad 3S 10 Z500M (P027)

    This software essentially unlocks the bootloader in your tablet. I've developed a way to switch a Mediatek bootloader into an unlocked state using root privileges. Luckily, the Z500M does give us temporary root access to run this tool. The result is an "Orange State" boot mode, which disables boot partition verification. As a bonus, this procedure does not erase your data like a typical unlock routine does. It also does not require a PC except to start the temporary rooted image. Note that your tablet will still lack fastboot flashing functionality. But flashing by other means is still possible.

    WARNING: Running this tool should be pretty safe. But I don't encourage anyone to try this. Before trying this out, consider the risks and drawbacks involved. By unlocking, you are essentially giving up the security of your device. It's also possible that a future firmware update will relock the bootloader or become incompatible with this tool.

    This software is only for ASUS model Z500M/P027. Do not try it on any other device. It will not work. Support for other Mediatek devices may be added in the future. (That's why this is posted in the general forum rather than the ZenPad 10 one.)

    And by the way, I don't own this tablet. :)

    DISCLAIMER
    This software is for educational purposes only. Anything you do that is described in this post is at your own risk. No one else is responsible for any data loss, corruption or damage of your device, including that which results from bugs in this software.

    REQUIREMENTS
    • A ZenPad Z500M tablet upgraded to Android N
    • A rooted/patched boot image such as one made by Magisk Manager (method 1)
    • Temporary root with Magisk or other superuser manager installed (method 1)
    • TWRP image (method 2)
    • Knowledge of adb/fastboot and of basic Linux command shell

    INSTRUCTIONS
    Method 1
    1. Read all of these instructions and make sure you understand them before starting
    2. If you don't have an offline patched boot image, use Magisk Manager to make one from the stock boot.img of your current firmware. Transfer it to your PC.
    3. Reboot your tablet into fastboot mode--either hold vol. down + power to power up, and select Fastboot. Or run 'adb reboot bootloader' while in Android.
    4. Connect your tablet to a PC and run fastboot boot patched_boot.img to start the rooted image in tethered mode
    5. Download the tool zip file to your tablet.
    6. Extract the zip to your /data/local/tmp folder.
    7. Open a root shell with adb shell, then run 'su'
    8. Change your shell current directory to that folder (cd /data/local/tmp)
    9. Run this command to unlock or lock the bootloader
      Code:
      sh unlockbl.sh
    10. Follow the instructions on the screen and type the requested confirmation into the prompt.
    11. Check for completion or any error messages. Report them here.
    12. If no errors, you are unlocked and may modify your boot partition (e.g. install root).

    Method 2
    1. Read all of these instructions and make sure you understand them before starting
    2. If you don't have TWRP for your tablet, download the latest image to your PC from this thread.
    3. Download the tool zip file to your tablet.
    4. Extract the zip to your /data/local/tmp folder. (For this method, most other folders should work as well due to permissive selinux mode)
    5. Reboot your tablet into fastboot mode--either hold vol. down + power to start up and select Fastboot, or run 'adb reboot bootloader' from Android
    6. Connect your tablet to a PC and run fastboot boot twrp-*.img to start TWRP in tethered mode
    7. At the TWRP welcome screen, do not select to modify the system partition and touch Keep System Read-only instead. Doing otherwise will render your tablet unbootable.
    8. Mount system in TWRP in read-only mode. Mounting in read/write mode will render your tablet unbootable.
    9. Open a shell with adb shell on your PC or open TWRP's built-in terminal
    10. Change your shell current directory to the folder that you extracted the tool zip into (cd /data/local/tmp)
    11. Run this command to unlock or lock the bootloader
      Code:
      sh unlockbl.sh
    12. Follow the instructions on the screen and type the requested confirmation into the prompt.
    13. Check for completion or any error messages. Report them here.
    14. If no errors, you are unlocked and may modify your boot partition (e.g. install root).

    New version uploaded. This one should have pretty universal compatibility because there is no more kernel module. Everything is done in userspace. It's a pretty significant overhaul. It might even work with other devices. ;)

    By the way, guys, you can now skip dealing with the whole patched boot image part. Now that we have TWRP, you can use that to run the tool. Just boot it with 'fastboot boot twrp-xxx.img'. Mount System inside TWRP. Then open an adb shell on your computer and continue as if you were running a rooted image. I will update the instructions to include this later....

    New version

    A new version of the tool has been posted that's compatible with patched images from FW 14.0210.1711.30. But it doesn't work with older releases. So pick the version that matches your image....
