I want to relock my bootloader to have the feel of Stock ROM once again. But I'm scared s**tless that I may screw up my neo. Currently I'm using Xperia Pureness ROM with suave kernel. What are the steps I should do to make sure that everything will go smooth. Your advice will be greatly appreciated.
No need to relock bootloader to use stock rom.
In case you really want it, for some unkown reason, flash stock rom and then relock your BL(depending on how you unlock it of course).
Do not relock your bl while having custom kernel in it.

The important thing which madyfish mentioned is "do not lock your bootloader with a custom kernel".
Exercise caution.

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.
Bootloader of my X10MP is unlocked right now. Will the bootloader be locked if I reflash stock 2.1 android using SEUS.
Please help: Urgent
No it wont be relocked unless u do it manually.
Note: if u are flashing back to 2.1 with SEUS u are on stock kernel or else u may hard brick ur phone.

Thanks a lot for the info....!! That means, once my bootloader is unlocked, I can anytime flash custom kernel with flashtool and install custom rom and if in the anytime I want to go to stock, just flash via SEUS....right!!

Yes.. and seus will install the stock kernel and rom in one clean install, so you don't need to flash another kernel or rom first.
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 everybody!
I need an help. Sorry for my bad english, I'm only 16 and I'm Italian.
I have an Xperia Mini, it's my first android phone, so I'm not very good at android modding! I downgraded it from ICS (Official) to Gingerbread (4.0.2.A.0.42 build) and I rooted it. Then I installed ClockWorkMod recovery. I don't have an unlocked bootloader, but I want to flash a custom ROM based on gingerbread. If I flash it, can I go back to stock rom with CWM's restore function? And If I can't, can I use flashtool to flash it (I have the .ftf file that I flashed for downgrading)?
Thanks very much.
Welcome to our forum
You can flash a gingerbread custom rom for locked bootloader with cwm, but be sure it is for locked bootloader!
If you take a backup in cwm, with backup/restore -> backup before you install the custom rom, you can restore this backup to go back to stock. Flashing the stock ftf will also work, you have to decide if you want to restore or flash, but if you take the backup in cwm it will backup the whole firmware with all apps etc :good:
Thanks! :good:
But do I need to flash a custom kernel? Or can I keep the stock kernel?

For locked bootloader custom roms it's the stock kernel :good:
For unlocked bootloader roms you need to flash a custom kernel, but this is only possible on unlocked bootloader

Normally it should work, but the problem is there's not specified if it is for locked or unlocked bootloader. It's stock based so it could work on locked, but it is recommend to flash a kernel. You could try it, but it could be you get a brick
When it's bricked, (mostly) you can't boot in recovery so you have to flash the stock rom with flashtool
Another little advice: If you install an ics custom rom on a gingerbread phone it could end in a brick. I had this when I was on locked bootloader, so I updated to ics (while keeping root, how to do this is in my rooting guide) and installed it again.
You can try an ics custom rom on your phone running gingerbread, just install it. But if it won't boot, flash the stock gingerbread rom and update it with root to ics
Ok. But before installing a rom, I have to do a full wipe, and wiping all will delete the CWM recovery?
I think I'll first upgrade to ICS officially. Can I use pc companion? or I have to flash the .ftf file of the stock 4.0.4 firmware with flashtool?

Read the instructions in the thread, generally you have to yes as it avoids any conflicts.

1.) make nandroid backup
2.) factory reset/wipe data
3.) wipe cache/partition
4.) format system
5.) wipe dalvik cache and battery stats.
6.) flash ROM
7.) flash supersu fix, there are lots of links out there just incase you have problems with root. this will solve your problem if u have locked BL
8.) if you lose CWM, you can use led deletes x-recovery tool to install cwm after you boot your rom
BUT TAKE NOTE THAT THERE ARE CERTAIN THINGS YOU MUST DO IN "SOME" Custom ROMS like Hasa(flashing lockscreen after 1st boot)
MAKE SURE TO READ THE THREAD's INSTRUCTIONS FIRST
Ok i read all the guides...now I'll update to ics and root it. Then I'll install a custom rom.

hi, im a bit of a noob at this unlocking bootloader stuff. Anyway, i unlocked my bootloader and put doomkernel on D6503 Z2. i want to relock my bootloader and remove doomkernel. i read this post: http://forum.xda-developers.com/showpost.php?p=45496437&postcount=2 . I dont get what it means by "before u relock bootloader u have to be on pure stock kernel (flash only the kernel.sin using flashtool)". Where can i get the pure stock kernel and how do i flash it with flashtool?
thanks.
