[Q] How to Root Xperia Arc LT15a 2.3.4 Build: 4.0.2.A.0.62

Decided to root Xperia arc, but don't know where to start.
I searched the forum and saw many posts on how to root 4.0.2.a.0.62 2.3.4, but these root guides were for the Lt18. I have the LT15a and from what I understand, Lt15 and Lt18 guides are different and are not to be interchanged.
Can anybody point me to the right direction? Thanks for your time.

I'm in the same boat as the original poster and want to be able to root my LT15a and install latest ICS but have been googling round in circles coming across lots of dead links and confused by some of the material I've come across - you need to unlock the bootloader/ no you don't. You can't root version 62 / yes you can etc.
The second post above goes to http://forum.xda-developers.com/showthread.php?t=1330314 but the thread is dead as are the links.
I have unlocked the bootloader but thats as far as I've got.
I've also downloaded
1) flashtool-0.8.0.0-windows.exe + flashtool-update-0.8.x-0.8.6.0-windows.exe and installed but not installed C:\Flashtool\drivers\Flashtool-drivers.exe as it contains 9 drivers and not sure which to use.
2) DooMLoRD_v1_Xperia-2011-ICS-ROOT-emu-busybox-su.zip
3) CWM-Install.rar
4) not managed to download an ICS image due to dead links or just not downloading.
There should be a straightforward guide somewhere.
Think I've found something here that allows install of official ICS (no mention of 4.0.2.a.0.62 just 2011 and 2012 Xperias) and then a follow up way of rooting. Digesting content but at the moment puzzled by statement that comes after ICS install "Its your wish if you want to stay on it but i suggest you to repair your phone software using SUS. It will reinstall the original ICS software in your mobile". This makes not sense to me i.e. why "repair" phone and why does it say, "It will reinstall the original ICS". The posting to use SUS 1(by 00rabh791) has "Here is how to backup firmwares..You need to reinstall the firmware". Possibly all makes sense once you go through the process but prefer to know exactly what I'm doing first.

Thanks for the info pren22 but I've only resorted to posting here because I've explored shed loads of 4.0.2.A.0.62 tutorials and got no where. A few links to these tutorials, that do not in themselves contain dead or unusable links, would be very much appreciated.
My aim is to install the latest official ICS

Xperia Arc lt15i Root Fckin` problem :|

Hi guys... 1 week ago i got my first android phone : an SE Xperia Arc lt15i ...
Ok .. So i updated it to ICS 4.0.4.587 with Sony PC Companion... Still no problems yet
I decided to root my phone because i wanted to use some apps that required root...
I started with this How To Root Xperia Arc/Arc S and running ICS Android 4.0.4 [4.1.B.0.431+4.1.B.0.587] ( from youtube .. i cant post links)
I mention that i`m a newbie at this chapter :angel:

Download the Sony Update Service and flash your phone with that software. It's easy to use, run it and you will see all the instructions

Did you get an error message on flashtool or did it just stop? If there was a message post it, if not retry with flashtool, it should still work even if the phone appears dead

Bro,I am new to xda.I've got one of this lt15i.Its on stock 4.0.4/4.1.B.0.587 and unlock bootloader says yes.
Does everyone here need to download Android SDK prior to flashing or rooting their devices?And when one does download the android SDK and run it on pcx64 it prompts to download java as well.Now I've got to files.So I double click on SDK and keeps prompting to download java.How do we overcome this as I believe it a must have application to connect both pc and device.I am stuck with these two downloads not knowing what to do next.
If there was a way kindly open a thread for newcomers to go into a post on how to get started on pc and then their device.
Thank you.

Hello, before I begin, I just want to thank you for your post is actually what finally gave me the final push to get an account here at xda. I know how it feels when you can't get a quick reply, or even worse, when you end up resorting to trial and error and brick your phone. So, I decided to create a new account to help people stuck in similar situations as well as to relieve the more experienced members of some of their load. Answering the same old questions can get pretty boring haha.
To answer your questions:
1) No, you will not require SDK if you're only seeking to root or flash your phone. Though, I have read some guides where they recommend you do so because you can also get the required usb driver files from there, though this is also not necessary.
2) I'm not too sure about your problem with Java, however, you do need to get it fixed because it is required for certain applications like flashtools. Have you tried uninstalling and reinstalling it. I used to have similar problem with Java, albeit for other programs. Perhaps one of the more experienced members around would be of more help if the problem persists.
To end off, I'd just like to express that I do agree with your final sentiments. I also started on my android journey alone, and it was a bit of a hassle figuring stuff out, especially after I unlocked my bootloader and couldn't rely on SEUS to save my ass. Well, feel free to ask if you have any questions. I'm pretty sure I'll be able to explain some details in an easier-to-understand manner.

[Q] Xperia Arc S LT18A root help 4.0.4

Hello everyone this is my first post so I'm glad to have all the help I can get as I am completely clueless on rooting(Real Noob on this really).
Ok so the reason why I want to root my Xperia Arc S is because I want to be able to completely put apps in the sd card and keep downloading apps without worrying about deleting app data/cache or even whole apps to get more apps installed. The Xperia Arc S's internal memory is really annoying. Even though you can move an app to the sd card part of it will still be in internal memory which will eventually fill up. So basically having apps on this phone without custom rom or being rooted is very limited.
Yes I've watched the user registration agreement video thing. I have been looking for 2 days now on how to root my phone but unfortunately because of my phone's model(LT18A) and it being 4.0.4(which I kept reading is unrootable), it is extremely hard. It's like, I am the only person in the world who has an Xperia Arc S LT18A ICS 4.0.4. I've found very few articles on how to root xperia arc s LT18A 4.0.4. I think first I gotta downgrade it to 4.0.3? Even if I find one, it's for LT18i(like 95% of all the xperia arc s) and most of the links for LT18A don't work anymore
So how do I root it? I got flashtool but the only firmwares I got are the one for LT18i and x10.
Xperia Arc S
Model: LT18A
Build number: 4.1.B.0.431
Android Version 4.0.4
Kernel version: 2.6.32.9

Read some sticky guides in general
If you want to unlock bootloader, rooting is veryyyy easy then.

Ok now I finally got to unlock the bootloader of the Xperia Arc S LT18a which I found really hard. Now I understand this enables you to install custom ROMs but the phone still needs to be rooted which I haven't done as I've tested with ROM manager.
So.....What does having it unlocked really do? If I have my phone rooted but the bootloader's locked, then I still wouldn't be able to install custom ROMs? Is that it?
Also, now with my bootloader unlocked, will I be able to access recovery mode like how people used to do with the Sony PSP?

Now to the hard part. To root Xperia Arc S 4.0.4 LT18A.
4.0.4 - Unrootable and have to downgrade. The problem is finding ftf files is really hard only because I have an LT18A model which is like being a unicorn..
I'll spend one more entire night looking for that rom and I'll let you know how I'm doing.

Getting started with Arc S rooting

Hi guys. Although I rooted my own Samsung ages ago, I haven't had to root anything in ages and my bro in law has asked me to look into rooting his Arc S.
What I seemed to be noticing is the need to unlock the bootloader first but I'm not sure where to start.
Is there some sort of 1-click method at all? He does want to stay with the stock OS so it is only the root he wants.
Thanks guys.

There are many possibilities to root without unlocking bootloader. Searching would have exposed you with many guides.
First of all - What are the Android version and build number of the phone?

Hi. I have posted earlier a working version of how to do it.
You can find it here:
http://forum.xda-developers.com/showpost.php?p=49240275&postcount=1378
This post shows how to get Ultimate HD on your Arc S, but has working links to programs and ROMs, so you can use that.
I personally do recommend Ultimate, because it is just so much smoother. My phone was lagging and all the programs were slowing it down, but now it's super smooth and I always have space in the ROM.
Soon I'll post a complete recommendation on how to get the most out of your Arc S.
Hope this helped.

thanks guys.
the android version is 4.0.3
the build is 4.1.A.0.562

These 2 topics will help you. Both root your phone, which one you will use, is up to you (which ones seems easier).
http://forum.xda-developers.com/showthread.php?t=1601038 - this one works only on 4.1.A.0.562
http://forum.xda-developers.com/showthread.php?t=2219711 - should work on every firmware

Hi, im a new member to this forum and im actually tryna find some help on how to root my xperia S (lt26i) phone. Im running the 4.1.2 version and although i found some guides, they are all made with different ways. I need some help on how can i root the phone because i have completely no idea about this stuff. I dont even know what means ice cream sandwitch, jellybean, kittkat, flashtool, Bootloader, kernel and all these terms i just wanna root this phone for better usage. Could someone show me a newbie way to do it? I havent done any change/configuration to my phone ever, i only typed a code on my dialpad and i found out that its "allowed" to root my phone.

I suggest You read up those terms first and then root. Even just searching those terms on Google and xda would do a lot good.

Download iroot >> www.iroot.com/
Install to pc
In Mobile allow > usb debugging (Setting>developer options>)
Connect with usb cable
Click root
Done

Try to root program like last comment also you can use kingo root. If it does not work,first you should check your firmware version.
generally Xperia S devices has 6.2.B.1.96 firmware version. This version has a problem with root and you can find how to root this version form xda

I used iroot and I says I've successfully rooted my phone. But it seemed very easy, is this a real root or I need something more?
