hello,
I have noticed that my otb 1.12 have less range with bl 3.9(hw unlock) unlocked with anysim 1.2u than 1.12 bl 4.6 unlocked. that's little strange. i have double checked if something has been broken inside the phone but everything is good attached.a bootloader 3.9 phone will loses more rapidly the network than a 4.6.everyone said that bootloader will not have any influence your phone, but then the manner of unlock perhaps?would it be possible to update to bootloader 4.6 as same as you downgrade to 3.9 only with other files?
