Hello,

Are you sure, that the Methode with Flashing Xperia Relock Bootloader over Flashtool works on Arc S? Many People mean, that i doesn't work on Arc S. Thanks in Advancd

i am sure friend
i have flashed it via flashtool ( Arc S)
also do check the replies in the thread, results are in front of you

And your phone was't destroyed/ any Bugs?

Because anyone say: Dont use on Arc S

My Android Version is.2.3.4 and my Build-Nummer .69... You've the Same?

Than i will Flash, if you can say yes xD and Sry if you don't understand me, im German and im at the age of 12^^ Better ask me, if you aren't sure what i mean

[Nabeel]

i don't have but i had the same ( build 0.62) did you understand me ??

i was earlier on 2.3.4 but now on 4.0.3
its totally your wish to continue
if you don't relock your bootloader then also you won't be able to get ics from sony as your bootloader is unlocked and you still need to use flashtool to relock it

but why don't use the flashtool to get the ICS ??

now i am on ICS-

and i completely understand you , don't worry :smileygrin:

Because i haven't got Much Know about that, i wait untill i get official ICS, and recieve Updates easily over SEUS... I've allready paid 50€ for repair my Bootloader.... In a bunch of Days xD (3Days Or smaller) ics is avaible in Germany and People have apready ICS in Germany and i hate my Bootloader xD sry for.my Fail English, bunch a smaller is completely wring, i doesn't Know Better...

this means you must relock your bootloader instead if you are not willing to flash using flashtool

then relock your bootloader
