@shivmahar83 Try sudo fastboot oem unlock then sudo fastboot reboot bootloader.

@Lakotaubp I also used it. One its show unlocked but after rebooting bootloader its again locked.

@shivmahar83 When it is unlocked, what happens when you run the Ubports installer?

[Lakotaubp]

@Rondarius Good idea

[shivmahar83]

@Rondarius The installation process stopped and below error shown through picture came.

@shivmahar83 Sorry for the late response. Try to reflash your phone to stock rom Android using this guide:
https://android.gadgethacks.com/how-to/complete-guide-flashing-factory-images-android-using-fastboot-0175277/
When you have installed the phone DO NOT REBOOT ANDROID use the Ubports installer instead while in bootloader.

@Rondarius Respected sir the above said factory image installation needs bootloader unlocked & my phones bootloader is locked and my phone is corrupted also. So I can't enable USB debugging and without USB debugging it is not possible to unlock bootloader.

Hi @shivmahar83 download the factory img: https://developers.google.com/android/images#hammerhead extract the archive, in the folder, there is a file called flash-all.sh, run it and see whats happens when you have unlocked the phone.

[shivmahar83]

@Rondarius Dear Sir I tried it already. I downloaded the factory image from google developer website, unlock the bootloader, and run the command flash-all.sh but installation stopped because of bootloader unlock problem. Because in reality bootloader didn't unlocked it only show unlocked. If I restart the bootloader it again shows in locked state.

@shivmahar83 said in OEM unlock problem:

bootloader.

Reboot your phone to the bootloader.
Run the following command whilst in the bootloader

fastboot oem unlock

Then, on the phone, select the "unlock" option.
Now, boot back into the bootloader, and run ubports installer.

Hi @shivmahar83 Do like this and see whats happens.

In the N5 factory folder there is this image-hammerhead-m4b30z.zip, extract it, in there you have another set of images.

right click an empty space in the folder, click 'Open terminal here', run these commands in terminal:

sudo fastboot oem unlock

sudo fastboot flash boot boot.img

sudo fastboot reboot-bootloader

sudo fastboot flash system system.img

sudo fastboot reboot-bootloader

sudo fastboot flash cache cache.img

sudo fastboot flasch recovery recovery.img

sudo fastboot reboot-bootloader

In bootloader run the Ubports installer
