First unlock boot loader because it wipes everything

 

[aviral sangal]

Yes i did read that on XDA. So i will first unlock bootloader and then proceed with other stuff

Obviously if one needs to install custom roms and recovery the boot loader has to be unlocked!

Boot loader unlocking is not required to install recovery & ROM. Boot load unlocking allows playing with your ROM (system files) and the space it occupied in your internal flash memory of the phone ... You could shrink the ROM and get more space in your internal memory! that you could install more apps. But it's a fail and not widely used, because now power users mostly share their external memory with their internal to get more space internally ...

Though I haven't played around with my phone much, pretty sure you need to unlock the boot loader in order to install a custom recovery.

Yup bootloader unlocking is surely required to use the 'fastboot flash' command to flash imgs.

I have no such issues at all. Maybe because I completely wiped my phone and flashed the factory image just to start afresh :smile:

http://android-revolution-hd.blogspot.in/2013/06/do-we-really-need-s-off.html You can't unlock bootloader without S-Off Some other facts: You don't need S-OFF to flash custom recovery image onto your device.

S-OFF is an HTC specific thingy. No such crap on Nexus devices.

First of all, S-OFF stands for "Security OFF" and S-ON for "Security ON". It's a term specific to HTC devices (and refers to digital signature checking on the bootloader "hboot"). Retail devices always come with SHIP S-ON locked bootloaders.

fastboot oem unlock - To unlock bootloader (wipes data).
fastboot oem lock - To lock bootloader (not sure whether it wipes data).
As simple as that.
