How to unlock HMD Nokia Phones Bootloader (for Windows) - HikariCalyx/OSTRemote GitHub Wiki

This tutorial is an updated version originally published on HikariCalyx.com. If you are a macOS / Linux user, please refer to the old tutorial: https://hikaricalyx.com/2018/05/30/guide-how-to-unlock-bootloader-qualcomm-t3769930/

Once you have the unlock key, go to the releases section of this repo to download the unlock tool: https://github.com/HikariCalyx/OSTRemote/releases/tag/1.0.0.u.milestone4

Where hmd_qualcomm_unlock_en_1.0.0.m4.exe is the English version.

We assume that you have already installed the relevant driver. If it is not installed, please download and install NOST: https://github.com/StollD/NOST/releases

Please open hmd_qualcomm_unlock_en_1.0.0.m4.exe, and here's the source code of it. Due to the use of Bat2Exe, it may be considered a Trojan, please allow it.

After reading the instructions, press any key to continue and disconnect your phone to connect to the computer. At this point the phone should be automatically placed into Download mode. When there is a certain chance, you will encounter a shutdown charging animation directly on the mobile phone. Please keep the phone's volume down and the power button to turn on when you keep the phone connected.

If the phone enters Download mode and the interface shown below appears, it means the computer has recognized the phone. If not, please check if the driver is installed correctly and the tail plug is loose. If necessary, it is recommended to contact the after-sales replacement tail plug and then operate.

To unlock the bootloader, enter 1 and press Enter to continue. After the prompt shown below, place the unlock key in the same directory as the unlock script. Allows you to use [your phone's serial number].bin or unlock.bin or unlock.key file names. The unlock key that is finally selected is based on the top of the three, and then press any key to continue.

If you are using Nokia 2, 5 or 6, just wait for the tool to tell you that the unlock is successful.

If you are not using Nokia 2, 5 or 6, then the tool will ask you to see the prompts on your phone screen. After the operation on the phone is complete, you should immediately return to the computer and press any key to continue, and wait for the next prompt.

If the unlocking encounters a problem, the tool will tell you why. For Sharp phones, if you don't encounter the error message shown below, your computer and Sharp's driver are not compatible. Please try to replace another computer or use the virtual machine to try to unlock.

If you need to change the slot, after returning to the main menu, enter 2 and press Enter.

If the current-slot is A, you should enter b and press Enter. The tool will switch the slot to B and re-enter the Download mode. At this time, you will try to return to the main menu and unlock again. On Nokia 2, 5 or 6, this feature does not work.

Overall, this should be much simpler than the previous unlocking method.
