Hi,
you won't get back your warranty just by flashing the original SE software and relocking your bootloader.
If you want to go ahead: As I am not allowed to "spam the forum" by link to an site... ask google this: arc relock bootloader
and take the first link.

[Q] R800X How to tell if Bootloader Unlocked

A month or two ago I unlocked my bootloader and rooted my R800X on 2.3.2. Ever since 2.3.3 has came out, I've wanted to update, but I cannot due to my bootloader being unlocked. Thanks to some very helpful instructions by a fellow XDA member, I did the instructions to relock my bootloader, but I am still rooted. Is that normal? How can I check to see if my bootloader is locked? I really want 2.3.3
You can check it by trying to use fasboot. If your locked, fastboot commands won't work (they'll come back with "you need root first" or something like that). Also, I think you need to do something to get rid of root and put the rom just like it was stock or the install might fail. Might try a factory reset. Good luck!

No if you root your phone that's all that will happen

I think it would be best if you flash your stock firmware to your phone first....as i have seen i lost both root & bootloader unlock after i did so...

I bought an xperia arc s two days ago..and I want to unlock bootloader/root/install CWM and costume roms..but some friends advised me not to do so and keep on stock status..because thsey claim that I may not be able to update the phone to the supposedly so near almost on the door ICS of android..is it true?and if I did the unlcok bootloader and rooted..won't I be able to revert back to stock and update to the ICS when it comes?what do u think guys..?thx in advance
If u unlock bootloader, u cant update through pc companion. However, u can always relock back the bootloader, allowing you to update using pc companion.
However, in my opinion, having an unlocked bootloader doesnt bring any downside (except losing drm) coz u can still flash ICS using flashtool or flash it as .zip coz the devs at our forum will surely modify it or something...
However,its all up to you

I think it doesnt matter which rom r u on to relock it as long as ur on stock rom. But I recommend using fw .42 to relock cause that was the firmware I usually use to relock.
Im right now using xperia s beta rom 5, doomkernel v19...

I think you can relock any baseband if you unlock the bootloader with the official se method. If you unlock it with a testpoint methode you cant relock it.

Unlocking bootloader

Hi!
I want to flash new kernel but earlier I must unlock bl. I will do this with official metod but i'm afraid that Sony and my operator(T-Mobile) dont wanna repair my phone when for example: my vol up button will destroy of using recovery, cause of unlocked bl. Can I lock bl when I will give my phone to warranty. Also I wanna know that, they wont be able to check that I unlock bl earlier?. Sorry for my bad english

They should repair all hardware issues so wouldn't worry about relocking it, any software issues can be repaired here.
When I will have software issue I will repair it by myself When I hear that Arc S wont have JB and any updates I decide to unlock bl. And last question. Can I relock my bl when I want and after that unlock again?
