Hey,
I would like to unlock my bootloader. In all the guides I've read, it says I will lose all my data.
I was wandering whether its possible to perform a Nandroid backup before bootloader unlock and then restore that data after bootloader unlock.
Could someone please tell ne if its possible?
BTW, I use a Sony Ericsson Xperia arc.
Thanks
Testpoit it. Its easier and you dont loose anything and not the DRM keys too. Easier to relock it too, as original

How would I relock my Bootloader?
Is unlocking a bootloader the same as making it simlock free?

No. Bootloader unlocking is not the same as sim unlocking. Bootloader unlocking allows you to install custom roms to your phone.

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.
Well It looks as if I Cant remove unnecessary apps on my Arc without rooting.
But here is something i wanted to ask before I go ahead with doing That
Q1) Is it necessary to Unlock My Boot Loader for Rooting or Rooting can occur without Unlocking it aswell?
I mean that I have read rooting without unlocking it but will it be the same locked or unlocked?
Q2)Unlocking My Boot loader means a 100% surety that my warranty will be Nulled right? (I Live in India, Rules don't differ here or in UK does it?)
Q3) If I have Rooted and NOT Unlocked my Boot Loader, Can I still update my Phone software through SE PC Companion? And Is my Warranty Still Safe?
Because I read that ICS will be available for Arc in the first quarter next year so I want to update my phone using SE PCC and NOT by flashing even though I know the pro's of flashing
Thank You so Much!

1. No you dont have to unlock BL to root your arc search for doomlords easy rooting toolkit
2. As far as I know yes
3. Yes you can still update with SE PC companion but I think updating via PC companion removes root. And your waranty is safe
You can use zegrush to root without unlocking bootloader. I live in India too. U can still update after rooting but not after unlocking. Rules apply everywhere.
Xperia Arc (rooted)
Thank you sooooo Much!!!
One more question
@Tatit1011- in reply to ur question 1, are dere any pros/cons of rooting after unlocking BL and. Rooting without unlocking it??

If you unlock your bootloader you CAN: flash custom roms, kernels(for overclock), and generally anything.
You CAN'T: upgrade via se, either pc or ota via the phone. Plus drm is lost, as is your warranty, but you can re-lock it
Generally, if all you want to do is remove system apps and use apps like titanium backup, root explorer etc then just root. If you want to try custom roms(there's only one you can flash over stock kernel, I think) then unlock the bootloader.

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...

you can unlock your bootloader by 2 methods
1)doing it thru official sony website
2)test point method...
when done using official sony website, you lose your drm keys(useless) but thru test point method you dont lose those..however, relocking bootloader can only be done on sony unlocked bootloaders to gain your warranty back.....
hit thanks if i helped.

First of all Many many Thanx for reply, Because i was waiting for reply many hours...
Actually i have unlocked xperia pro boot loader without any safety knownlodge but know i relise...
So relocking bootloader will back warranty again??ARE U 100% SURE????
is there any danger from deleting drm files to warranty?
i m going to hit thanx button on ur reply, please reply fast
see drm keys are used only for stupid purposes like trackid and othr utterly useless stuff drm keys never cause problems for warranty because people who use their phones normally can also lose those drm keys...
and yes, relocking a bootloader will give you back your warranty(thanks to sony who does not keep a record of unlocked bootloader phone's imei number)
but remember that relocking can only be done on bootloders that are unlocked using the official method...
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.

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 ?
