Rooted samsung galaxy s4 using odin& CF Auto root. Then flashed CWM using rom manager. Now I can go to CWM recovery mode (using power+volume up+ home) . I can get NAndroid backup. Does this mean that I have unlocked my bootloader? After a lot of googling I think I should use ADB 'fast root in order to unlock bootloader. but since I'm already booting cwm in recovery mode others say I'm alreay unlocked!!! the method I used from http://autoroot.chainfire.eu/ isn't for unlocking its for rooting. please explain Thanks. actually now that I read the instruction in chainfire website don't understand why rooting worked for me he has a warning that using those auto root files on a locked bootloader will brick the phone!!!

  • Welcome to the Android Enthusiasts! If you want to add details to your question, please don't do so via comments; you can always edit your question ;) Apart from that: Was that you asking the same question yesterday? CWM installed does it mean bootloader is unlocked? – Izzy Aug 30 '14 at 13:19

  • No reason to re-post as duplicate. You can always contact staff asking to have that account "merged" into your current one. If you can provide them the registration details (to prove it's yours), they usually do. – Izzy Aug 30 '14 at 13:26
  • @Izzy can you read the question again please? I have changed it – Sam Aug 30 '14 at 15:30

Not necessarily, just because you rooted your android device doesn't mean that you unlock the bootloader. You must understand that is very different root from unlock bootloader and they have different uses too.

Root your phone means that now you have the sudo permission(admin permission) and you are able to manage your android as you want. Remove stock apps, edit the system files (that is dangerous if you doesn't know what you're doing!) and lot of new possibilities.

boot unlock your phone means that you can install a custom recovery boot, like the most knows: ClockWorkMod (CWM) and TeamWin Recovery Project. And also be able to install a custom ROM like CyanogenMod, Paranoid, or other Android Open Source Project (AOSP) ROM.
As different devices have diferent methods to unlock the boot, it should search on google with your exact model and how to unlock it. But most devices uses fastboot as the unlock method (Sony, Nexus - Samsung not, I used odin too).

Yes, it can brick you phone if you don't make it right. The tool CF-Auto-Root explicit alerts:

UNLOCK BOOTLOADERS If you have locked bootloaders, flashing one of these will probably brick your device - with the exception of Nexus devices, which will usually automatically "OEM unlock" and wipe your data !

How to check if your device is rooted:

How to check if your device is boot unlocked:
Please check search on google for tutorials, because change for each brand and model. But note that it is more an advance feature than a simple root and easily could get you phone wicked if somethings went wrong.

  • "boot unlock your phone means that know you can install a custom recovery boot, like the most knows: ClockWorkMod (CWM) and TeamWin Recovery Project" I'm using CWM so I should be boot unlocked right? I did alot of googling to confirm that I have boot loader unlocked but didn't get the answer (using Samsung Galaxy S4 SGH-I337M) – Sam Sep 1 '14 at 2:17
  • @Sam Sorry, but so I didn't get so what are you asking for. I read again, but It is the same I has thought you asked... – lcsvcn Sep 1 '14 at 2:24
  • ok I understand that rooting isn't same as bootloader unlocking. I want to know that if I installed CWM with rom manager successfully does it mean that I am already boot unlocked? – Sam Sep 1 '14 at 2:33
  • I didn't find any method to check bootloader for my device no one said how I can confirm if it is unlocked or not. – Sam Sep 1 '14 at 2:37
  • I think you should not be able to unlock automatically, as the site warn you to be careful. And I explained in the answer that to unlock the bootloader you should search on google for methods for your device as it change for each model. – lcsvcn Sep 1 '14 at 2:45
