[Q] dont know if i have to unlock bootloader first - Verizon Samsung Galaxy S III

i recently switched to teamwin and i was wondering do i still have to use ez unlock to unlock the bootloader???i was using cwm with ez unlock and ez recovery..i go through goo manager and hit reboot recovery from there it goes into teamwin,do i have to use ez unlock first then go into goo manager?? please let me know..thanks..

You only need to unlock the boot loader once. As long as you didn't specifically lock the boot loader or flash back to the stock image then you still have an unlocked boot loader.

thank you for the reply

LOCKING BOOT LOADER
You need ADB so follow these steps.
To lock your boot loader you definitely need to have a proper connection between your device and computer.
To re lock your boot loader you need to:
1. Turn off your device
2. Hold your volume down button and press the power button. (KEEP HOLDING YOUR VOLUME DOWN BUTTON) You will see a white screen with fastboot written on it.
3. Navigate with your volume up or down to fastboot and press the power button to select it.
4. Connect your device with your computer,
5. Open the terminal in your computer and type in 'adb devices',
6. Type in 'fastboot oem lock' without quotes and your device is locked again, you will see relocked.
but i don't know the status of my bootloader.. if i have bootloader unlocked, i can re-use the zip to back to stock, that it includes relock bootloader
and if i have bootloader locked, i will unlock it
how i can know if it is unlocked or locked? thanks!

You could try flashing a custom recovery to it. If it works, then your bootloader is unlocked.

Only try to flash a custom recovery. If it works, you have unlocked bootloader.
Remember that locking back your bootloader can brick your tablet, and that locked bootloader is not needed for the updates.
I unlocked twice my unlocked bootloader and notting happened, it said "it's already unlocked" or something similar, but do at your own risk.
i dont flash a recovery yet but.. i can enter to android system recovery <3e>
does this mean that i have bootloader unlocked?
thanks!
EDIT. i flash twp2 and it works.. so i hadn't have my bootloader locked..
sure, i'm gonna flash ICS.. no more JB now

[Q] The warning won't go even after relocking bootloader.

Hello guys,
I have a Moto G, Dual Sim variant.
I decided to lock my bootloader, but even after i locked the bootloader back, the warning on the boot screen won't go
Can anyone help?
Thanks in advance!
Fix
Im assuming you're talking about the screen saying "Warning Bootloader Unlocked"??
If so, unlock your bootloader, get a custom recovery like CWM or TWRP.
Follow the instructions over here:
http://forum.xda-developers.com/showthread.php?t=2548530
Download the second zip in the OP, "logo.zip"
Go to your recovery and flash it.
Your Warning Screen should be gone

This will remove the unlock message but if you check on the fastboot screen your phone will still say locked. code 2 Once unlocked you can relock the bootloader but you can never get back to a locked code 0
Forgot to mention that. What he said. Once you unlock your bootloader, it will never be 0. If you try to go for warranty or something like that, I'm assuming that's how Motorola or whatever will know you unlocked your bootloader and hence, voided your warranty.
Thank you everyone, I just wanted to unlock the bootloader because i am giving my Moto to my brother

I'm not sure I completely understand you. When you try to unlock the bootloader does it stay locked? Or does it unlock?

Do a factory reset in the recovery.

Sounds like you have a bad emmc. You likely need to send it in for repair.
