I tried the manual version through ADB and the "fastboot flash radio radio-toro-i515.ek02.img" command kept erring out.took the cdma, but not the base... gonna try with this and see how it goes...


Well I finally just gave in and used WUGs utility and I now have a stock phone again... NOT FOR LONG... LOL

I had to seriously do some hunting on this one... your directions should read... fastboot flash radio-cdma radio-cdma-toro-i515.ek05.img

Just so ya know.

The instructions worked perfectly on my unlocked gnex with 4.0.4. Thanks for the guidance. FYI: I was unable to download the script to try it.

I'm unlocked, but not rooted. Can this still apply? I think I need to exchange my phone.

All you have to do is reboot into fastboot and use adb to lock the bootloader.

If I may ask, why would you be unlocked, but not rooted?

It took some guts just to unlock my boot loader, so I just kept putting rooting off.

Can you please provide for specific instructions for using fast boot and adb to re-lock the boot loader? Will it be enough to turn my phone into Verizon?

I should add that I have Android SDK installed.

Trust me, you have to relax. I understand the anxiety, these phones ain't cheap! However, this is a developers phone and was meant to be played with. No matter how bad you think you may have jacked it up, it can almost always be restored. Sometimes the methods are harder, but the end result is the same. I have rooted, flashed about a dozen times, restored to stock, went to Verizon for service, rooted about another dozen times, went back to stock, had Verizon look at my device again and now I am on my 5th flash. These things are very durable.


Now, back on topic. If all you did was unlock the device, all you have to do (provided you have the necessary drivers for ADB) is follow the last two steps of the first post. Open a command prompt (hold down windows key and letter "R" and then type "cmd" without quotes and press enter) and navigate to the ADB folder ex. type "cd desktop\New Folder" without quotes and "New Folder" being the name of the folder you created on your desktop with the ADB files. Your command line should look like this: C:\Users\username\Desktop\New Folder>

Then:

Type - "fastboot reboot-bootloader"

Press enter (the phone should reboot to the Android Guy)

Type - "fastboot oem lock"

Press enter

After that, when you reboot the phone you should see the white Google logo and nothing else. If you still see the white unlock symbol at the bottom you did not unlock it correctly.

Good luck!

This message has been lingering for 10 minutes or so and I've tried a couple of times, restarted my phone, computer, with no success. USB debugging is enabled too. Any other ideas?
