OEM unlock problem

joe

@joe Did you try the following command in your terminal? : "sudo fastboot oem unlock" 1rst of all be sure you've got fastboot package installed (sudo apt install fastboot) and adb (sudo apt install adb).

@shivmahar83 There must be something wrong with your description, if you did not unlock your bootloader then it cannot show unlocked.

Anyways, you can always go to fastboot mode, unlock the bootloader and re-install the Google factory image or continue from there with the UBports installer. It is virtually impossible to brick a Nexus 5...

Just for more info what was on the device before you started. Stock android or something else? Is there a chance the partition sizes have been altered. That will stop UT installation. As Flohack said something is off in some way. I know you have tried before but does - fasboot devices - show your device when run.

@joe Dear sir I try many times "sudo fastboot oem unlock" command in my Ubuntu PC but one time its show unlocked but again it shows unlocked after rebooting bootloader.

@shivmahar83 can you please try just fastboot devices and let us know the result. The more info we have the easier it is to help.

shivmahar83

@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.

shivmahar83

@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.

Rondarius

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.
