[Verizon] Help locking bootloader

[xboxkid]

I need to get a warranty replacement for my phone. So I flashed a stock rom and unrooted (using this app https://play.google.com/store/apps/details?id=com.universal.unroot&hl=en). Now I am trying to lock my bootloader. I am using the adb commands but it is not working. This is what happens:

C:\android-sdk-windows\platform-tools>adb devices
List of devices attached
01498A000C01B008 device

C:\android-sdk-windows\platform-tools>adb reboot bootloader
(this works fine and the phone does what it should up to this point)

C:\android-sdk-windows\platform-tools>fastboot oem lock
< waiting for device >

And it just gets stuck there.

Please help. I am completely lost here.

Hey there,

Happy to try and assist.

Is the fastboot utility located in platform-tools?

 

[xboxkid]

Yes it is

If you type fastboot devices in the command line, does it return a device id?

 

[xboxkid]

nope, its not returning anything

 

[jhawkkw]

Then it sounds like the fastboot drivers aren't set up properly. I would try reconfiguring them.

 

[xboxkid]

How would I go about doing that?

Open up the device manager while the phone is connected in fastboot/bootloader. You should see and unknown android device or an adb bootloader interface driver listed. Right click on it and choose update driver software. to manually update, click browse and then click select from a list of drivers. You should see a list of samsung drivers and you want one of the more up to date ones. Let it install, and then retry the fastboot devices command. If it returns a device id, then you should be set to try locking it again.

That worked. Thank you so much!

Cool, I'm glad that it worked out for you. Hopefully you get a good refurb.

Thanks for stepping in Hawk. I was on some potty training duty. Glad it worked out!
