I have Xperia Arc LT15 with GB 2.3.2 before & found out using *#*#7378423#*#* that I cannot unlock bootloader. I was disappointed as I was using CM7 & CM9 on my HTC Wildfire & ZTE Blade. So I decided to go with the official ICS update. But when I checked after the update it says "Bootloader unlock allowed : Yes". So the question is can I unlock bootloader now & install CM9 or other custom ROM using this (http://wiki.cyanogenmod.com/wiki/Sony_Ericsson_Xperia_Arc:_Full_Update_Guide) method?
Yup, you can unlock your bootloader.

Testpoint it and dont loose drm data. Easier to relock also.
Typed down from the sky with sexy LT15i
+1 for the testpoint method of unlocking. It is the safest and best.
Testpoint method advantages:
1. You keep DRM keys
2. OTA updates with S1tool unlock, I'm unsure?? It is safe with SEtool (paid) testpoint unlock, coz I've done an OTA myself after getting SEtool unlock done by jinx13.
3. No warranty loss.
4. Even carrier locked phones can be unlocked, although this is usually a paid service using SEtool instead of S1tool.
Sony official method might be free, but it is terrible because:
1. You lose DRM keys
2. You could wind up with a bricked phone if you are on an official Sony rom and install an OTA update.
3. It borks your warranty.
4. Carrier locked phones can't be unlocked at all this way.
Bootloader unlock allowed : Yes
it mean you can unlock your phone
Whaaaaaat?!!nofake? Updating the arc with official ics unlock bootloader?! Do it works for all the arcs?
Was it a piece of luck?
Plz respond quick I using jj's rom so I wont test before I ll be sure that it works...

Hello! If i unlock my bootloader on my xperia neo and then lock it again will i lose my warranty?(i want to root my phone and seems that OTA update is not working so i want to try the method wich implies unlocking the bootloader)Thanks in advance!
Yes you will, unlocking bootloader deletes DRM certificates so even if you relock, sony will be able to tell i beleve the payed method of bootloader unlock does not delete the certificates though

Hello.
To root your phone you just have to downgrade to a 2.3.2 rom with wotanclient, root with gingerbreak and do an OTA update (no danger during the update as long as your bootloader is locked)

Is DRM keys the only big issue? If so, I can see that that can be worked around. I asked Sony about this today and they said that a lot of issues they see with their phones are as a result of modding, so if the BL is unlocked, you lose your warranty. I don't want to ruin a 2 year warranty on new phone. Yet, as Doomlord pointed out, Sony offered users to test the ICS which involved BL unlock...I'm confused.
OK, I updated My Arc to a .62 Latest Firmware via SE PC Companion.
Can you tell me how to root it now?
There are options available right?
I have a Locked Boot Loader and Dont wanna unlock it.
Thanks Alot!
it aint possible without an unlock. Get a pro to unlock it for you. Costs about 15 quid warranty and drm remains intact.
Downgrade to .42 or .58 firmware with Flashtool and root it using the zergRush exploit.
@somedude67 - My DRM can be saved even after unlocking my bootloader??
How??
Any free way?

No, there's no free way, contact e.g Jinx13.
Hello, I'm new here, with a new xperia arc.
I have .42 firmware and I want to root, but i have a question about it.
My phone is stock, locked bootloader, untouched...plain stock; If I root with doomlord rootkit I void warranty or it's safe?
I've seen that it is a un-rooting kit there, but it works well in case i want to unroot?
And if I root now, and update via pc companion the future ICS 4.0, it will be ok with the phone and all right?
I just want to root but not to void my warranty, or unlock the bootloader, or to flash another firmware or system.
Thanks in advanced
It won't void the warranty - but not 100% sure as I don't really about warranty
And yes, you can update to 4.0 later

Thanks, I still have 2 years of warranty and i just want to be safe
So, can someone confirms that this tool Xperia 2011 Easy Rooting Toolkit [v4.0](zergRush Exploit)( http://forum.xda-developers.com/showthread.php?t=1320350 ) don't unlock the bootloader and don't change the phone except giving root privileges? As I said, I want this for the warranty and stability of the phone
(had bad experiences with my former LG GW620 phone last year :-<)
Thank you again
planning to unlock boatloader of my Play, but according to the Sony method, warranty will void, and even faulty hardware itself will not be covered by warranty.
found another way to unlock boatloader using the point-test thing, but seems to be kind of risky too.
may i know most of you guys here used which method to unlock your boatloader?
in a great dilemma now!
why not unlock and relock.
You can unlock and re-lock your bootloader.
Unlock using: http://adfoc.us/423185576865
And relock using this : http://adfoc.us/423185576880
I'm not 100% sure that sony can test that it was unlocked after re-locking but it does indeed work with SEUS after you bootloader is locked back.
I did search the forum, and found methods for Arc, but none for the Arc S.
Is there any way ?
Also what are the disadvantages of losing DRM? Read somewhere TrackID and Timescape won't work. I can live with that. Anything more ?
timescape work fine in my lt18i with an unlocked bootloader
They use the same methods.

As i know you can't unlock your bootloader at the moment without lose the DRMs.
Use the offical way.
You can unlock bootloader without loosing drm via testpoint paid service with setools

You lose the ability to use things like Trackid
Read from somewhere, that test point method is not supported on Arc S, but is supported on Arc. Someone tell me more.

Official method only works for generic, unbranded phones. If your phone was purchased through a carrier, its bootloader cannot be unlocked.

SETool1 doesn't support the arc s (LT18i), only SETool2 which requires hardware and paid credits.
Frequently Asked Questions about the bootloader:
In short, with the available methods, i'll lose DRM on my LT18i if i unlock the bootloader, right ?
i heard that it isn't possible to unlock the bootloader after the date 12w11.. mine is built in 12w36 so no way to unlock the bootloader.
if i use this video (unlocking via testpoint) it works? Because in description is standing if there is standing bootloader unlock allowed: no you have to root it at first!?
mine is rooted and there is still standing no so can i unlock my phone with testpoint!?
A friend has the xperia arc (lt15i) and a guy from Handybörse (so it's called in germany) unlocked his bootloader but at phone were standing 12w24 !?
i dont know how he unlocked it but it works and before there were standing no and now there is standing yes??
So i can unlock my lt18i with this video (sorry its in german but i think everybody know what this programm is and what it means)??
Thank you guys
Hope for fast answers!!

No, you are one of the unlucky ones, who can not unlock bootloader at all.
Removing sim-lock/branding does not allow you to unlock your phone, because fastboot is disabled and only way to enable is via test point method, which is impossible at the moment for the phones manufactured 12W11.
ohhhhhh...
but it worked at the arc from a friend...
there was standing unlock allowed no and he disabled sim/netlock and there stand bootloader unlock allowed yes..
manufactor at 12w14 :/
so i dont know

Mine is also after 12w11 and I unlocked official but I had a badblock @Sahaab also couldn't unlock his bootloader so dude face we are stuck with a locked bootloader if you want a newer android version buy a more recent phone

the bootloader isnt the problem. but i want to flash any kernel to overclock my phone. but i think this isnt possible on my device so ill forget it. i dont want a better android version. i only want to use my gingerbread roms faster and use all of them. thats why..
im happy enough if i can flash kernel
But to flash custom kernel, you need to unlock your boot loader, which is impossible unless you get rid of the carrier lock.
