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.

stock 4.0.4
11.0.A.4.22

[Q] Question regarding the Xperia J

Right now I have the 4.0.4 Android( stock version) of the xperia j with locked bootloader and I've rooted-it and I've also installed the CWM.
I would like to install Cyanogen Mod 10.1 but since I have the 11.0.A.7.5 firmware I have locked bootloader and I can not flash it.
My question is if I can flash an older stock firmware and by doing so will I be able to unlock my bootloader?
From what I understand right now since I have a locked bootloader I can only flash stock ROMs so if that is correct than can I just flash an older stock ROM, one that will allow me to unlock my bootloader and than flash CM 10.1 on my Xperia J?
And another question- I know that by unlocking the bootloader I will also loose my warranty but from searching the XDA forums I saw that I can make a backup copy of my stock ROM and flash it to relock the bootloader again. Is that accurate ?
Thanks in advance for your help!

First is your bootloader unlockable. Then you can unlock on any firmware via sonys website. I dont think there's a cm10.1 released for j. If you unlock your bootloader you will loose DRM keys forever even if you relock they will still be gone that's how Sony will know your bootloader was unlocked.

It is not unlockable, that is why I wanted to flash another version of a stock ICS.
Won't that allow me to unlock the bootloader ?
From what I understood right now I can only flash stock Roms with the locked bootloader, is it correct or since I have the "NO" status at the bootloader I can't even do any of that ?

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!
