You can unlock it but you have to pay for it, something like 25 bucks and unlocking it that way with the testpoint you won't lose your drm and ota updates won't brick it

Regardless of firmware, your Arc 's bootloader should be unlockable, unless stated otherwise.

You got a unloxked bootloader
Download superuser.zip from their site. Put it in sdcard
Hotboot a kernel with CWM
find it in dev selection. Put it in fastboot folder on your pc
Fastboot code
Fastboot boot YOURKERNELNAME.IMG
Phone reboots. Press volume down on blue led.
Install zip from CWM menu

Going back to full stock

Hi
I am looking to fully reset my arc to orignal sony Ericsson fw
so can someone point me to the latest stock fw (preferably India fw) and the guide on how to flash it
My bootloader is unlocked and i am using CM10 right now
Sent from my Xperia Arc using xda premium
If you want to get country specific software best way is to restore via Sony Update Service, but you need to relock your bootloader to use that method. For unlocked bootloader you can use flashtool to flash a ftf file but I cannot guarantee that it is India stock firmware.

Relock ftf : "C:\Flashtool\firmwares\X10_V1_BLRelock.ftf"
u dont need to unlock your bootloader just:
Download ftf file from here: http://www.qosmodro.me/2013/01/all-xperia-2011-official-stock-firmware.html
and flash it via flashtool.

If that website did not have the ftf file he will need to relock the bootloader to use SUS. SUS will determine his location and let him download the specific firmware for his phone since he was looking for Generic India firmware.

SUS is noob friendly and you don't have to find the files on the internet. The program will download it for you.

If you know how to use flashtool, you can download the ftf file from the link from the previous post and flash using flashtool. If you're not sure how to use it then use SUS, but relock the bootloader before using SUS.

Look here if u want to unlock your bootloader - http://forum.xda-developers.com/showthread.php?t=2650510
And no you don't have to flash the ftf right after unlocking bootloader, you can do it anytime... Unlocking bootloader and flashing ftf are two different things

Hello Kaml,
Im not sure if rooting "by unlcking bootloader" is the only option you are considering but you dont need to unlock bootloader to root 4.3.
I rooted my Xperia on 4.3 following this thread: http://forum.xda-developers.com/showthread.php?p=51730927
If you want to unlock bootloader anyway, please, make a backup of the TA partition first: http://forum.xda-developers.com/showthread.php?t=2292598

Rooting with locked bl is too complex i didnt get it clearly and didn't used these tools before :/
Can someone please explain it to me clearly what to do
Sent from my C1904 using XDA Premium 4 mobile app
Hi Kaml.
Yeah, it's a bit confusing when you first go to it. If you dont like the adrenaline/fear/expectation mix, better is to ask someone else to do it for you
You say that's too complicated to root with a locked bootloader. That’s not always true, it’s relative. The post I linked to you is very clear and it’s not complicated at all, but you will need to start from a 4.2.2 rooted ROM, maybe that’s the complicated part for you.
Anyway, I suggest you to confirm if you can unlock your bootloader. Did you checked it already? It may save you time by knowing it beforehand.
To check, go to the dialer and type: *#*#7378423#*#* then go for Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you are able to unlock it. This is from thread http://forum.xda-developers.com/showthread.php?t=2484622
Read that thread, especially when it says “before unlocking please take backup TA partition from here”. By backing up the TA partition you can restore it later if need and then you have some chance of not losing Sony warranty if you ever need it.
Im not aware of other methods for rooting 4.3 besides the link I posted on my first reply, take a look and you will find other methods (probably).
Anyway, if you are interested in backing up the TA partition, it’s only possible if you have a rooted phone already and that’s kinda of a chicken/egg problem so that’s another motive of seeking for rooting methods without touching the bootloader at first. One way to solve it is to half root your phone, enable USB debugging and Unknown Sources from development menu, then run the script to backup the TA partition.
