[Q] How do I upgrade to 4.0 with a LOCKED Bootloader? PLEASE HELP =)

Hey guys! As the title states, Just trying to figure out a step-by-step way to upgrade my Arc to 4.0+ whilst having a LOCKED BOOTLOADER.
I am unable to unlock the bootloader and understand this causes quite a few problems.
I already "bricked" the phone once..had to repair it to get it back to stock again. I don't want to go through that again..
So, it would be greatly appreciated if someone could kindly direct me to, or outline here, a step-by-step guide to installing ICS on my Xperia Arc.
Thanks for all your time and help!

Use flashtool to flash the official ICS release.

Hey thanks for the quick reply. Do I need to have root before upgrading? And also, do I need CWM recovery?
Can I just use flashtool to flash the ftf file?
Thanks again for the help. Much appreciated

Just flash using flashtool, it flashes the kernel too. I think Binary has added a root file too.

There is an update you need to apply to flashtools if you have version .6 you need version .7 look in stickies for flashtools... Info in that thread.

If your phone is Xperia Arc(LT 15i) I recommend you to wait the official update of ICS for arc, at this moment ICS is available for Arc S. I have Xperia Arc but i use a custom ICS rom with custom kernel, and bootloader unlocked.

Thanks everyone for the info.
My Xperia is LT15a, but I recently got it repaired and now it says LT18a instead. =S
Android 2.3.4
Baseband: 8x55A-AAABQOAZM-203028D-64
Kernel: 2.6.32.9-perf - [email protected] #1
Build Number: 4.0.2.A.0.62
Bootloader is Locked
Can I still upgrade?
Thanks again for your time and help!

huh ? i do not understand... is it okay for the repair shop to do that ? . . . there are several h/w differences between last year's model and this year's model to 'require' the new internal s/w to properly talk to the new h/w ( drivers... )
.
please correct me if i am wrong.

[Q] How to get root access on Xperia Arc LT15 i build 4.1.B.0.431

Hi All,
I have currently updated my Xperia Arc LT 15i to build 4.1.B.0.431. I haven't rooted my phone till now. Its my first time and I want to know step by step procedure to root my device.
Thanks,
Saurabh Malhotra

There's a thread dedicated to rooting 4.0.4. Find it.
Next time ask your question in the q&a forum before a mod locks this and you don't get an answer
Edit: Well it got moved without being locked.

There is thread dedicated to rooting flashed 4.0.4, not stock 4.0.4, so I am also wondering how to root my device!

There is a working root for 4.3 if u want update phone OTA to 4.3 then root or if you can't OTA u will have to flash the 4.0.4 method.
The mod will lock this so please view the forum dedicated to this.

By stock do you mean updated through pc companion or seus?
ATM there's no way to root without flashing
Sent from my LT15a using XDA

So many threads about rooting ICS, if you come from 4.0.3 rooted then you must do the OTA (over the air) to update to 4.0.4 and you will keep the root, very simple and indeed there is not yet a root kit by Doomlord so ne patient and not posting tons of threads how to roor 4.0.4, right uppercorner stands...SEARCH
And is that not possible to do the ota flash then a costum rom

By the way Sony has released an update for the 4.1.B.0.431...so now its the 4.1.B.0.587 which is the newest update...i would recommend you update it to 587 from 431 and then root it

I have followed everything to a tee, the guide and stickys and still can't do it?

Build 4.0.2.a.0.62 cannot be rooted, you have to downgrade to build 4.0.2.a.0.42 using flashtool and root that,then update over the air to build 0.62

[Q] Root LT18i 4.0.2.A.0.62 ?

Hi guys, i have flashed LT18i 4.0.2.A.0.62 to my Arc S, it works fine but i Wanted to clear the bloatware so I need root for that.
I couldn't find any direct method (forund the one to downgrade o .42 then to root, but it's too much hassle), can it be done?
Also if easier and anyone knows which ROM i can flash with any Stock 2.3.4 without bloatware + CWM etc... i just don't like custom roms, as it
turns default works just fine for me.
So:
1. How to root stock LT18i 4.0.2.A.0.62
2. Link to pre rooted 2.3.4 (LT18i 4.0.2.A.0.62) stock kernel + cwm - bloatware

You can not root. 62 it is no hassle to use flashtools to flash The.42/.56 root then update ota ( only if bootloader Is locked otherwise you will brick your phone)

Flash Doomlord kernel v22 (with corresponding Wi-Fi modules) and voila - you got root access!
