i have read for a long time and try some roms who didint say req bootloader unlock but all stops on sonyericsson (bootloop) maybe it is here someone who try and work with a specific rom ...
Maybe they aren't saying that you need unlocked bootloader, but if "kernel" is mentioned, then you need that kernel and kernel flash need unlocked bootloader.
Practically every custom ROM needs it's own kernel, so I'm afraid you'll have to unlock your bootloader.
My manual said that only if defects were caused by custom software, I'd might have to pay for the reparation.
Yes i know but i come from Htc where it was easy (root and redy to install everyting) and now i`m stuck but i don`t give up my garanty for this it maybe later it will apear some roms only with root
tnx all

[Q] Prerooted image without unlocked bootloader?

Is it posible to flash a prerooted official image with digital signature (if that exists) without having the bootloader unlocked?
my problem is that i can't unlock my bootloader because of my phone company, but i recently flashed the new ICS to my phone and it worked perfectly. this wasnt a problem apparently because it was signed by sony or something and the bootloader didn't complain. so, does there exist a rooted but official image i can flash without unlocking the bootloader?
Thank you all in advance. im really frustrated by not being able to root my device :crying:
hope somebody can help.

[Q] 3 questions about bootloader, custom rom, sim unlock

1) the bootloader unlock allowed :no?
i have managed to root but i wanted to in stall custom roms.
2) if i cannot unlock does that mean i cannot install zips or install a custom recovery?
3) is there anyway to sim unlock the phone to all networks
Xperia u - ST25i
thank you for your help
2) Of course you can but just ROMs and Mods for locked Bootloaders. The thing you can't do is for example flashing a custom kernel to install KitKat, Jelly Bean or other Android Version above 4.0
3)yes there is own. Ask your provider for that. He can give you proper informations. But as far as I know it's pretty expensive to unlock the SIM Lock. Telekom in Germany wants 100€ for that..

2) yeah I managed to root and custom recovery. Apparently I'm not allowed to unlock my boot loader so I'm stuck on 6.1.1.B.1.54 :/
Is there a list of ICS locked boot loader ROMs?
3) Wowsers.
And thank you

1- Have phone replaced by Sony, not all countries' service centers are willing to do so and you must generally have it SIM unlocked first
