Hello Zebra Community,

I'm exploring options to unlock the bootloader on the TC520k for potential development and customization. I understand these devices are typically locked for security purposes, but I'm curious if there are any official or unofficial methods available.

Has anyone had success unlocking the bootloader on the TC520k or similar Zebra devices? Any insights or guidance would be greatly appreciated!

Thanks in advance!

Hi there,

Unfortunately we do not share anything public on how to unlock the bootloader of our devices and as you mentioned it's strictly for security purposes.  We do however provide ways to temporarily do it in case the system or any partition for some reason is getting corrupted blocking the normal booting sequence of a device - And in that case you'll have to flash separately each partition with fastboot.

Hello,

I have device that we did OS update (A10 > A11) from card and after update device boot, but it just stuck on "Zebra" logo screen.
Eventually it display "<!>"  ..... corrupt.... .
I fastboot mode checked device info and notice that Verity mode is false.

Is there a command from fastboot level or zip file from recovery menu that can fix verity mode to be "true"

Hi Daniel,

Thank you for your prompt response.

I appreciate the clarification regarding the security protocols. Given the situation where the system or any partition is corrupted and blocking the normal booting sequence, could you please provide more detailed guidance on how to temporarily unlock the bootloader? Specifically, I am looking for:

  1. The steps to temporarily unlock the bootloader.
  2. The commands to flash each partition using fastboot.
  3. Any precautions or specific instructions that need to be followed during this process.

I have a working TC520k device and another one that is stuck in fastboot mode. Any assistance or detailed steps to resolve this issue would be greatly appreciated.

Thank you for your support.

Best regards, Forhad
