[Completed] [Q] Help request- Rooting Sony Ericsson Xperia Arc S LT18A - XDA Assist

I have an old smartphone (model specified above), which I have tried to find a root for it (like FOREVER), and misrebly failed. I think that the problem is that I own the LT18A model, while every single root I found was worked for the LT18I users (as it seems in the comments).
I want to root it so I can uninstall some of the build-in apps that I dont use (such as facebook, youtube, and out-of-date & un-updateable operator apps.). They function poorly, take up space, and worst of all: they run in the backround (and on old phones such as this every megabyte of RAM counts.) Please help me.
Is there something I'm missing? A vital step a skip or something? Do i need to unlock the bootloader to root?
I probably have a custom ROM of the operator this phone was originally purchased from, does it make any difference?
If Anyone can explain to me step-by-step what and how to root, or point me to a usefull guide, i will be forever thankful.

rooting without flashing on xperia neo?

hello xda,
First, congratulations for a great work that you are doing here.
I am a newbie in android, and my son bought my wife a Sony Ericsson Xperia Neo, OS GingerBread fortunately upgrade to Ice Cream Sandwich is available, so I upgraded it.
My question is, is it possible to root this phone without flashing?
The reason I'm asking this is because I cannot play music from external sd card, only the default music and she don't like the list.
I have transferred more than 150 song to it but cannot play it.
I have downloaded some folder app but i can only play music one at a time.
I have read somewhere here that i need to root in order to be able to play music and not the default one.
Can someone please help or guide me to this problem, or maybe anybody can recommend some apps that I can download so I don't have to root?
Thanks in advance.

Help Rooting/Installing JB Rom on Sony Xperia Tipo

Hello everybody,
First of all, I'd like to apologise if I'm posting this in the wrong thread, I'm kinda lost, as I'm new to this website and the smartphone world in general.
See, I've just bought a Sony Xperia Tipo ( http://www.gsmarena.com/sony_xperia_tipo-4718.php ) in the UK, and I moved back to my country (Peru), so my warranty is already voided.
What I wanted to do was to root and install a JB Rom (admittedly, I haven't found much information about this, and even the beginner guides I found confusing).
I was thinking on doing it without asking by following this tutorial on how to root a Xperia Tipo ( http://androidadvices.com/root-sony-xperia-tipo-st21a-android-phone-tutorial/ ), then I found this other one in the XDA forums http://forum.xda-developers.com/showthread.php?t=1890478 and http://forum.xda-developers.com/showthread.php?t=1971370 but the comments were somehow discouraging and the instructions were more than confusing for my slow working brain (sorry!).
Then I read that Sony Xperia Tipo does not support the unlock bootloader function ( http://2e0b66ea.yyv.co/ - from the official sony xperia website), does that mean I won't be able to install a cuztomized JB ROM?
Now, I've also searched through the forums and found http://forum.xda-developers.com/showthread.php?p=28929562#post28929562
Having said that, I would very much appreciate a rooting guide for dummies for the Sony Xperia Tipo (or should I just use one of those tutorials i posted?)
Will I be able to install the JB ROM I mentioned on my Tipo?
Thank you guys so much in advance for any future replies and I apologise for the stupidity of my question, but I had to ask before bricking my phone.
P.S: Needs to be said that I just bought the phone, so I didn't make any configurations or anything, was waitign to see if I can root my headset first.
you can unlock boot loader for tipo
as it is confirmed by sony official website
check it out...............
they updated there website..........

[Completed] [Q] Help request- Rooting Sony Ericsson Xperia Arc S LT18A

I Know I aleady posted a thread like this, but it was closed before a found a solution, please dont close this one too!
I have an old smartphone (model specified above), which I have tried to find a root for it (like FOREVER), every single root I found wasn't able to do the job. Either the program alerted me that the phone is not supported , or tried to root and failed. I have looked into other threads with the same problem, and they either didn't have a solution, or simply directed me towards stickys with rooting programs that also didn't work.
I want to root it so I can uninstall some of the build-in apps that I dont use (such as facebook, youtube, and out-of-date & un-updateable operator apps.). They function poorly, take up space, and worst of all: they run in the backround (and on old phones such as this every megabyte of RAM counts.) Please help me.
Is there something I'm missing? A vital step a skip or something? Do i need to unlock the bootloader to root?
I probably have a custom ROM of the operator this phone was originally purchased from, does it make any difference?
If Anyone can explain to me step-by-step what and how to root, or point me to a usefull guide, i will be forever thankful.
The file attached is a example to one of many failed roots.
