Hi,
I have a Motorola U6 (PEBL) which I need to unlock. I have searched the internet and it seems that RSD Lite will work. However, I cannot find a downgraded bootloader which works with my phone.
I have another U6 which has been unlocked. Is it possible to retrieve the Bootloader from the unlocked U6 and use it to unlock the new U6?
Any help would be grately appreciated.
Thanks.
