So , reading about how to install Ubuntu on my Nexus 7 ( on ubuntu install - official website ), I found this :
If the device is already unlocked, skip to Step 3. These steps will wipe all personal data from the device.
- With the device powered off, power on the device by holding the Power button + volume up + volume down.
- The device will boot into the bootloader.
- Plug the device into the computer via the USB cable.
On your computer, press Ctrl+Alt+T to start a terminal. Type sudo fastboot oem unlock, followed by Enter
- On the device screen, accept the terms of unlocking.
- Boot the device by pressing the power button (pointed by an arrow with Start on the screen).
What makes me anxious is that 'sudo fastboot oem unlock' that makes me wonder : is it reliable ? Should I unlock my bootloader using that method ? ( considering my tablet is still stock and haven't unlocked / rooted it ... ).
What do you think , guys ? Or is that available only if you are going to install Ubuntu right away ?
Also , the other methods - like wimme's one - come with that ' superuser installer ' included ...
Is anyone able to explain me this things ?
I only used tools ( for my acer and for my defy ) to unlock bootloader and root the phones - never used terminal...
