I installed the B927 rom on my Ascend. Since I found it really slowed down the phone, I decided to use the V6 Supercharger script, which required to root the phone.
My mistake was when I used unlockbootloader.exe : although I just needed to root the phone in order to get the script to work, I also clicked on the "Unlock Bootloader" button, and so I guess I unlocked the bootloader. I've understood doing this is necessary to use clockworkmod , but I don't need this (unless I'm missing something).
I read that unlocking the bootloader may void the warranty of the phone, and that's why I'm a little worried, I didn't intend to go that far into modding the device.
It seems easy to unroot the phone ,but is there also a way to undo the unlocking, and do as if I did'nt do it?
