So, suddenly my phone started showing, unfortunately, google play music has stopped and it did the same for almost every app..and restarted on its own...and after some research, I came to know that it went into a boot loop because it is continuously loading...and does not start after that.

Android version: 6.0.1

With zero knowledge of android and two days of google search, I tried the following things, however, nothing has solved the problem and my phone is still not working.

I tried:
1. ADB sideloading: I switched the phone to recovery mode, and selected apply update from ADB. I found the firmware file for my model from the official Asus site and executed the following command from my pc -
adb sideload UL-ASUS_Z010-WW-

However, it showed the following error:
sideload error

I was not able to find a solution to the error.

2.Secondly, I tried flashing the boot image available in the extracted firmware file as follows:

flash boot img

Even after that...it kept on loading with the logo on the screen and never started properly.

Maybe everything that I have said and done is wrong, and I am sorry for asking such a silly question. Please help me, to get my phone working properly.

  • I think this is a misunderstanding. The boot image is just a very small run-time which is executed at the beginning of the boot process. If it is finished it loads the system or the recovery. I assume that the installed bootloader works without problems, but your installed OS (containing the kernel and the system partition) is still broken. I would recommend to flash TWRP recovery via fastboot, boot it and then try to sideload the image you have. Alternatively search for a custom ROM with a more recent Android version for your device.

  • So, for me to do anything, I am not able to unlock the bootloader...it says access denied, even with the unofficial method. Can you suggest me any method? Apr 1 '20 at 13:10

Aside from ADB sideloading, there is a direct option on the phone called "Apply update from SD card" after entering fastboot mode. Maybe, you should try that.

  • Enter fastboot mode by pressing the Volume down and Power button at the same time.
  • Once you reach the main menu, look for the above specific option.
  • On the SD card, the correct firmware zip file required for your phone should be present. Do NOT rename it or alter it.
  • After entering the option, locate the firmware file on the SD card and select it, apply the changes.

If the problem still persists, I think you should dig deeper into how to unlock the bootloader of your phone.
