You can't run a custom kernal with a locked bootloader it must be stock. If you want to relock your bootloader and restore drm keys you need to flash stock kernal. If you want to stay on custom kernal and restore drm functions, have a look in the cross development section for the drm restore mod.

no, usually the rom contains the root, do u mean custom kernel?
what rom are u using? stock rom go with doomlords v6
custom roms go with what the dev provides u with
I'm a bit confused.
Please go read the Android Dictionary here, (Clickie!)

Hey guys, I'm gonna get a brand new Xperia X10 Mini Pro in a few days. I wanna install MiniCM7-2.1.9, and to use that rom I also need to install the nAa kernel, which requires an unlocked bootloader.
So my question is, say if I need to revert everything back to stock (rom, kernel, lock bootloader), for warranty purposes for example. Well, I know that the kernel and rom can be flashed back to stock using flashtool or SEUS, but what about the bootloader?
If I remember correct, you have to lock the bootloader first or else an unlocked bootloader won't work with a stock rom & kernel, which will result in a hard brick right?

Bootloader cannot be locked again. So if you are unlucky, you will get brick and lose garanty. =)

Yes, sorry, i am used outdating info((
ya I did my research and S1Tool can re-lock the bootloader. But am I correct though? My question wasn't really answered...
You have to flash back to stock rom and stock kernel if you want to re-lock your bootloader. Just when you're on stock rom/kernel, then you can safely re-lock your bootloader.
Hello everybody! I'm about to buy an Xperia U, and I have a few questions about bootloader, CWM and phone models.
I used to have a SGM which didn't have bootloader, locked and unlocked stuff, so i'm kinda lost here.
1-I see that there are some tutorials to unlock bootloader. Ok, if I unlock it, will there be any differences? Is it really needed?
2- There is CWM for locked bootloaders, but if i'm gonna flash some ROM, it will have to be for locked bootloaders or I can use any ROM after having CWM?
3- CWM backups Stock ROM?
4- Any physical differences between St25a and St25i? Can I flash a St25a ROM in a St25i phone?
5- If I update Xperia U from GB to ICS via official sony software, I can unlock bootloader after updating or I need to do it while on Gingerbread? Or I'll have to unlock bootloader while on Gingerbread and then flash official ICS ROM via Flashtool?
I guess that's it, if I remember something more i'll ask.
Thanks in advance
Sorry for my english
EDIT: Wait, Titanium Backup doesn't work on locked bootloader?

1.Unlocked Bootloader is not needed unless you are to install custom roms,kernels and stuff.It doesn't make difference in performance.
2.NO,you can only use roms which are for locked bootloaders.
3.It backups all the data of stock rom.if you want to revert to stock rom again you will have to flash it.
4.Don't know about physical diff,and also not sure about flashing st25a on st25i.it may harm your handset.but only difference is in baseband.
5.you can unlock whenever you want.But I guess once you unlock bootloader you can't use pcc or sus.(pc companion and sony update service) for updating your phone.But again,you can relock your bootloader anytime.
If you are going to flash it via flashtool you will need to unlock the bootloader first.
Told you all I know.if I helped anyhow hit thanks.
I am also a noob.so,if I am wrong anyone can correct me.

1. Leave it locked, safer until you get used to messing around with the device.
2. You can only use Rom's for locked bl.
3. Yes, with all your apps and data.
4. I have st25a on my st25i, no hardware difference.
5. Unlock bootloader on 2.3 or 4.1, you can only root with ICS afaik.
Also be aware that most sim locked Xperias cannot unlock bootloader ever, get yourself a sim free device if want unlocked bl.

Hi!
I have only a little question. I have CyanogenMod 9 on WT19i (LiveWithWalkman). Of course I have unlocked bootloader. I want to go back to stock ROM and unlock bootloader. I have to only flash old ftf .62 and flash relocking file or it is more complicated?

No you don't... You don't have a locked bootloader...
I don't think there is any CM ROM for Xperia active with locked bootloader...
If it exist do you mind passing the link for it
BTW running CM on stock kernel too bad

You are mistaking with the meaning of unlock/locked boot loader. Phone comes with locked boot loader then it is unlocked for full throttle. If u want to go back to stock u dont have to relock the boot loader again. Just flash any ics kernel & then stock rom. Or u dont have to flash a kernel if u are gonna flash a ftf
Sorry!
Sorry. Very stupid mistake . UNLOCKED

Yes just flash the ftf and if you want to root, just flash a prerooted kernel for gingerbread, but stock kernel will be flashed with the ftf :good:

Hi,
It's easy. First flash stock ftf via flashtool.(Check xperia M device forum for ftf file.)
then restore TA partition and voila..done.
EDIT: flashing ftf will wipe out custom rom so don't worry about it.
