Bootloader unlock: no? Theres some trick to unlock it. Dont know if it can be done on :no tipo as we have yet to find tipo testpoint. For :yes tipo just use easy method in xda.
Now using:
Sony Xperia tipo ST21i
stock 4.0.4
11.0.A.4.22
(rooted, locked bootloader)
Current problem:
Cant get past installing flash drivers in xp.
Even testpoint requires unlockable bootloader.. Advantage is we can retain DRM keys.

I have updated Xperia J from ICS to JB. Its bootloader unlock allowed says YES but its not unlocked. The phone is in warrenty. I want to go back to ICS 11.0.A.7.5 as rooting is hard in JB.
I have some questions:
1. If I flash with flashtools, is it necessary to unlock the BootLoader?
2.After flashing ICS, in future If I want to flash JB with Flashtools, will then I have to unlock the BootLoader?
I dont want to unlock BL as the phone is under warrenty.
Thanks....
As far as I know Flashing ftf file using flashtool doesn't require boatloader unlock bro. And it won't unlock your bootlader. So if you flash ics, the boatloader will still be locked. And you can use flashtool at any time to flash jb ftf.
Hit the thanks button instead of telling it....
thank you

Hello, Do i need to unlock bootloader to downgrade via Flashtool? Sticky threads say yes, but I'm using Flashtool since 2010 series and never had to unlock bootloader just to downgrade, or flash stock ROM. Another question is ROM 11.0.A.7.5 Central Europe from this thread willbe good, or i need other rom? http://forum.xda-developers.com/showthread.php?p=44115119
I'm on latest JB now 11.2.A.0.31 and want to downgrade to latest ICS 11.0.A.7.5
You can via Flashtool via flashmode

if you wan,t to flash stock firmware then no need to unlock bootloader.
cause you flash firmware (*.FTF) using flash mode not fastboot(bootloader).
so you don,t have to worry of unlocking bootloader.
ok, thank you for your reply!
