If u don't relock bl don't forget to relock before sending back to Sony (your warranty will be voided) if not though, u may aswell leave it unlocked

[Q] Help re-locking bootloader on sk17i

I have a xperia mini pro with unlocked bootloader and nerodroid rom. Now I want to turn back to the stock rom and re-lock the bootloader. Can you tell me which is the easiest way to do that?
*When i unlocked the bootloader I said "ok I will flash the stock rom with Wotanserver when ics will be released"(I know ics has not been released yet) And now I see that I have to pay to flash the stock rom with Wotan
**Sorry for my bad english;$

I recommand to download flashtool -> download .ftf file to relock BL -> flash with flashmode -> then update phone with SEUS (not PC Companion).
EDIT:
Many times (about 6 xD ) I use this method to relocking BL and flashing back to stock with SEUS.
OH.. I'm not responsible for any damages... Just for safety

yeah, back to stock den flash any ROM yhu wish to use via CWM!
I think PCC will not update/restore firmware because when unlock BL with fastboot damage DRM so PCC will not provide firmware.
I read this on the formu, but can't remember the thread name and I'm not sure that is true. Also I don't try restore via PCC.
is sure use SEUS to go back to stock kernel?
sorry my english
yhu can try SEuS but i know for sure PCC will work too provided BL is locked.....!

Regarding Bootloader Unlocking: Urgent

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.

[Q] Stock rom from CM

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:

For sure, you can flash with SUS or PC Companion, BL must be locked.

Currently I have a custom Kernel and Rom.
So if I relock my BL I can download and flash the stock rom and kernel with SUS or PCC?
Do these apps even recognize my phone without the original kernel?

Yes they'll flash relocked BL, in SUS you select the type of phone you have, I don't know for sure what will happen with custom rom because my BL is unlocked but I have relocked and repaired with PCC before.

Doesn't work.
Both SUS and PCC tell me that the software on my phone has been modified.
Edit: ok, I think I got it. Relocked the bootloader first with flashtool.

[Q] relocking bootloader

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?
