[Q][Update] Some Basic-newbie Questions

Hi everyone, i just bought a Xperia Arc and its currently running Android 2.3.2
My questions are:
1 - Which is the latest version update for Xperia Arc ?
2 - I tried to look for an update using the "Sony Ericson PC Companion" but it says that there is no avaible update. Why is it happening?
3 - The fact that my carrier is "VIVO" (From Brasil) means i can´t update my Phone?
4 - Is there any "Safe" (I know every way may brick your phone,i´ve flashed tons of custom roms on galaxy phones) way to update it to the latest version (or at least to 2.3.3 where i´ve seen some cool features) without breaking my 3G connection with my carrier ?
5 - I Know ICS is going to be released for our phones,but,will the update be Global or Carrier-by-Carrier like ?
Thanks in advance for any help/answers.
I will stay tuned here !

Flash with flash tool.
Debrand it with generic 2.3.4

Can i flash a "Global" Rom that works in every country,with every carrier ?
That would solve my issue,if theres any 2.3.4 (Which i found to be the latest version) rom (STOCK ROM,not CUSTOM) that i can flash safely.
Waiting for answers.
Where are you developers ?

Read the stickys.

Search for flashtool and read how to use it.
Then search for 2.3.4 generic world and flash it with tool above.

Thanks,again.
Last one,do you mind linking me a "how to" guide so i can follow it?
I´ve found this on on Youtube,but im not sure if its the same step-by-step: http://www.youtube.com/watch?v=JmmThXTWu74
Also,Flashing this global rom,will prevent some apps from SE like TrackID to work or whatever ?
I´ve read it here : http://forum.xda-developers.com/showthread.php?t=1133650

Look in general and devs section, there are tutorials.
Im on phone so i cant copy/paste link to it.
Someone will give you link,or ask flo95 for it.

But I dont want to unlock bootloader and lose the warranty and OTA update

I did it just few minutes ago and no need unlock BL
1. Flash to 42 or 58 firmware by flashtool. I download from below linkhttp://forum.xda-developers.com/showthread.php?t=1357841
2. Root ur phone by flashtool again.
U can change the CDA before use US or PCC then back to orginal 62 FW.
Cheers
PS.sorry my poor english

Solved
1. Unlock the Bootloader
2. Install Doomlord Stock Kernel 1.6 ( Pre rooted)
3. Install .62 stock Kernel from .ftf file (Root remains from Doomlord Stock Plus Kernel 1.6 even after installing .62 Rom kernel agian)
4. Re-lock the bootloader with the help of Flashtool.
5. You have Stock ROM rooted and with locked bootloader.

Download Arc S LT18i (4.0.2.a.0.62 Offical ROM) : http://www.mediafire.com/?6fs6iry9spv78mb
You can install Arc Rom on ARC S by some tweaks but it makes your ARC S slow as the default CPU speed in ARC is 1 Ghz and our ARC S is 1.4 ghz by default.
Download the .ftf file from the above link and install it through Flash Tool.

@jaipurwasi80 Thank for answer and help.
I think the problem(arc s as arc(cpu)) can fix with overlock and upgrade 1,6 or 2,0 ghz,cant it?

I have used the same file for my Arc S( LT18i) and its worked fine for me along with the Latest Flash tool. I hope you are using the .ftf file in Flashtool and your phone in flashboot mode.
OR
Go to www.wotanserver.com and download its client on your PC to Install any Offical Sony Ericsson ROM. You need to make a free account on the site and while installing you can choose to install 4.0.2.a.0.62 offical ROM.

[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] Installing ICS on xperia play with 2.3.2 (rooted locked bootloader)?

Can I inctall ICS on my xperia play with 2.3.2 (rooted locked bootloader)? Some websites say you have to have android 2.3.4 (latest update) in order to do so. Thanks

I wanna say that you would need an ICS kernel , which you would need to unlock your BL for.. and the system on your phone wont matter, since ICS isn't official on our plays your will need to instal a custom Rom which will overwrite everything anyway

Thanks

Well I did some reading and I think you will need an unlocked BL and at least be on the .42 firmware, 2.3.4 like you originally posted. I know there are a few ICS roms that work in the developer section. But I think for the official beta release your gonna wanna follow what Sony said.
Edit: looks like you have to fastboot a boot.img and userdata.img and system.img

You'll be able to get ICS without an unlocked bootloader once the official update is released, since the official releases can be made into files for flashtool.
Aside from the fact it'll be done through SEUS.

New Arc S firmware [4.1.L.0.8]?

Apparently, a new firmware was just certified in PTCRB.
Does anyone have any info on this?

Wow, more updates!
Does anyone know what is the update for?
Sent from my LT18i using xda premium

hope this one will be as smooth as GB.

hmmm looking forward to see what new features fixes does it have. hopefully it is not a regional framework only.

looks like it is a carrier/region specific update..btw one update for arc s is on its way..

It,s the same 4.0.4 but for a carrier in the UK

I'm not have update ?

I believe it's the 4.0.4 ICS UK update for 3.
At least that's what was reported by one of our other members.
Sorry if that dashed your hopes. LOL!

How will this work as I am on 3 and my Phone has officially updated to 4.0.4

The .431 kernel is not root-able. I think you meant the the 4.0.3 kernel

My phone is branded to `3` and to concur with xtacy above , it recently updated to this firmware .

Hmm. Does this only occur on unrooted? I am on 3 and it just says I have the latest software if I check in PC Companion?

did u flash an ftf to update ur phone or get it through update official ?

I used PC Companion to flash then ran Doomlord root bat file. I take it I won't get any official update unless I remove root (probably have to do repair to do that though right?).

I have a notification saying FW 4.1.B.0.431 Is now available. Anyone know what it is? Don't want to update if it's just a few fixes for 4.0.3.
