I am very new to this forum.
Can i use the flashtool to flash this firmware WITHOUT unlocking bootloader/voiding my warranty?
Odp: [Q] Flash with locked bootloader?
Yes. You can install all of the Sony fw. But it must be original firmware. You won't loose your warranty and you don't have to unlock your BL.

Hi I recently bought the sony ericsson WT19i (Live), now I want to flash cyanogenmod but i don't know how. I read something about unlocking bootloader bu I can only find tutorials for Xperia range phone's also is there a way to backup my current ROM and EFS partition?.
I have alot of expirience with android so just some links should do.
Also is there a way to Re-Lock the bootloader?
You must unlock bootloader first. Then flash custom rom, and install cm using update zip.

Thanks but unlocking avoids warranty and no official updates. Is it worth it?
From what i understand with a locked bootloader you cant boot into recovery, right?

Ssory my english is bad. I am russian user.
With unlocked bootloder you can not oficially update you device.
You can install cwm to locked stok rom and boot into recovery.
Unlock bootloader only need to flash modded kernel.
after unlocking you can lock bootloader. Drm key's not restore

I have SE Live With Walman, and it's rooted with doomlord's rootkit, however my phone doesn't allow bootloader unlocking. So, i was wondering if there's any rom that doesn't require unlocked bootloader and costum kernel.

is there any other option i can try...plzz lemme know

If you are using stock. 54 tft file, it doesnt matter if your bootloader is locked, it will work on both. If you want to use Rom for unlocked, then you need to keep bootloader unlocked all the time you are using the Rom. If you flash unlocked and then relock it, you will get bootloop.

If it is Sony stock tft file, then yes, its working on both, locked and unlocked.
If its customized Rom based on stock, then read the OP.

Do you have a ST25a or ST25i? If you're installing an ST25a on a i you should exclude the base band in flashtool and the other way around. I don't know if this causes the boot loop, but it might be worth the try.
Yes... But a boot loop isn't necessarily. It's the best probability. Maybe... Just vibrate and nothing else.
Hi guys!
My Xperia Z Ultra is on the 4.4.2 firmware, but I want to go back to the 4.3.. Can I go back without unlocking the bootloader? Does it work just flash the 4.3 firmware or do I have to unlock the BL?
Thanks.
You can flash 4.3 using flashtool. You don't need an unlocked bootloader. However, you may have to check "wipe data" for this to work.
