[ROM] Official Sony ICS 4.1.A.0.562 NCB Generic + ROOT [Update: 15.04.2012]
- Thread starter Bin4ry
- Start date
Until today, I still hard to decide whether to update my Arc S from GB to ICS or not. Though I have read several posts and topics on the advantage and performance of ICS, ICS still not yet be rooted unless unlock bootloader. And I don't want to go for that unlock bootloader only to mess up the device.
Still I need some more advice from you all, if possible in simple details around this ICS. As some idea said that ICS use up more RAM and CPU while my device has only 512 RAM and a single core. Also I have many applications and huge games installed, which would make me lazy to reinstall everything from scratch. Moreover, those applications are always up to date.
Thanks for reading my post, and I'm waiting for your all advice.

Install v6 supercharged update 9. It really a big help for ICS on my Arc S.
now my Arc S almost as smooth as GB.
Have you tried to root by using the OP method? It's simple.
just extract in a folder and connect your phone and run the RunMe.bat
for the memory management, v6 supercharged really helps.
Do I need an unlocked Boot Loader and Root to Install or will an unrootd Arc S with locked Boot Loader be able to Install, as I'm itching to get The Official ICS ROM?

you can just flash the ftf file with flashtool 7.0 without unlock your bootloader.

I don't understand why some are getting crazy screen control. My device had that on GB but since ICS update mine is perfect now. Very strange. My thoughts were the screen has been fixed. Also I noticed if you have a screen protector on that can cause the touch sensitivity to go off the rails. If you do try removing the protector and see if that helps.

Ok, sot the ftf file and Flashtool acts like the Installer packages that you can download and install for HTC headsets?

Guys!
I flashed the ROM and it worked like a charm, with no errors while flashing or what so ever.
I have:
Xperia Arc S LT18i
Locked bootloader
Unrooted
BTW: This is my first flashing experience EVER! I'm a noob and never tried those thing before.. I just couldn't resist the temptation of ICS and could't wait any-more.
IT"S VERY EASY!
Here are the steps precisely (I followed the steps from http://www.xperiablog.net/2012/04/1...roid-4-0-ics-update-to-your-xperia-arc-guide/ )
And they are as the following:
Downloaded the ROM from: (they are 2 parts)
http://www.mediafire.com/?c3iklzhze6tlr11
http://www.mediafire.com/?rv37jysrbl1rg6a
Note: This whole thing does not require you to root your handset and it does not require you to unlock your bootloader.
1) Install drivers for the Xperia arc
The very first step is to make sure that your PC has all of the necessary drivers installed for the Sony Xperia arc. The best way to do this is to install PC Companion or Sony Ericsson Update Service (SEUS). Make sure you connect the Xperia arc to the PC before starting the process to download the necessary USB and ADB drivers. If you have any problems you will find the necessary drivers once you have installed Flashtool in the following location: ‘C:\Flashtool\drivers’.
2) Switch on USB debugging on your handset
Switch on the debugging option on your Xperia arc. Go to Menu –> Settings –> Applications –> Development –> Tick ‘USB debugging’
Also tick ‘Unknown sources’ under Menu –> Settings –> Applications
3) Install Flashtool 0.7.0.0
You must ensure you install Flashtool version 0.7.0.0 for this process to work. The older versions of Flashtool do not have the command to handle the new ICS partition resizes.
As the official Flashtool site is currently not allowing a download of the necessary file, you can download it from our mirror here. The zip package includes two files: 1) Flashtool 0.6.9.1 and 2) an update zip file.
a. Install the ‘flashtool-0.6.9.1-windows’ application.
b. Once complete, unzip the ‘update’ file. Move and replace all contents of the zip file to C:\Flashtool.
c. Once you have done this, launch Flashtool. The log window should show that you are using ‘Flashtool Version 0.7.0.0 built on 2012-04-14 11:34:01′. To make sure of this you can always go into Help > About to see what version you are using.
4) Download the Generic Nordic ICS Xperia arc S firmware
Download the Generic Nordic ICS Xperia arc S firmware from here (377MB). This is firmware version 4.1.A.0.562 which will update your phone to Android 4.0.3.
OR, in case the download is slow, you can go from here (as described above):
http://www.mediafire.com/?c3iklzhze6tlr11
http://www.mediafire.com/?rv37jysrbl1rg6a
A note of warning: Some browsers like Opera will rename the extension of this FTF file as a zip file when trying to download it. Make sure that the downloaded file has a .ftf extension rather than .zip.
5) Place firmware in correct location on your PC
Place the FTF file in the C:\Flashtool\firmwares folder.
6) Launch Flashtool
Open the Flashtool application on your PC. Click on the lightning bolt symbol. Select Flashmode and click OK.
7) Select firmware
Select the correct firmware in the left column (LT18_4.1.A.0.562_NCB). Check the boxes (‘Wipe User Data’, ‘Wipe Cache’ and ‘No Final Verification Check’ all need to be ticked).
8 ) Connect Xperia arc to PC
Turn your phone off. Press and hold the back key while plugging the USB cable into your Xperia arc.
9) Flashing process will start
The flashing process should now start. Once you see the “Flashing finished” message in Flashtool, remove your handset from the PC and wait until the phone reboots (this may take some time so don’t panic).
10) Your Xperia arc should now be running ICS
Congratulations, your Sony Xperia arc should now be running Android 4.0 Ice Cream Sandwich!
That's it, guys!
Thanks for posting this very useful walkthrough on how to flash the ICS Update. I've flashed before but on the old X8 and my Wildfire S always ad updates OTA.

OK, I surrender with this ROM, I don´t know why after a while using it with no problem, and after rebooting a couple of times, my phone doesn't get mi SIM card, it says that its invalid and I loose signal. WIFI works ok, but not sim card.
If I go back to Baseband 64, the SIM card works partially... Invalid Sim card, but signal works.
What a Stupid issue

Is this a problem with Arc LT15a variant? I saw another member who complained about the exact same issue after updating to baseband 70 and even reverting to baseband 64 was causing the same issue.
Loving my Arc LT15i after flashing ICS, its very smooth, I have more free memory, the battery lasts longer, the interface is refreshing nd new but the best of all is the stock browser, its smooth nd fast nd the screen not jumping around while scrolling up or down
Just one problem as i cannot repair my firmware with PC companion. My phone is stock LT15i and i live in India

i'm new with unlocked bootloader. jz 1 silly question, how do i root with the script provided in post 1? kinda blur.. flashed custom kernel to get rid of the 0% battery that has been bugging me for days. the only thing now is rooting it.. don't wanna screw up again
I don't know where Sony get the idea that the ICS Update will mqke your phone run slower than on Ginger Bread, it's running just as fqst as Gingee Bread but with the added bonus of more App Memory, better battery life, better Widgets apart from the Facebook & Twitter
Widgets for the Official apps are the same old Widgets from when I was running Eclair on my X8. Also now I can disable the Office Viewer 6 app as it's the only stock app that is none unenstallable (as I use Documents To Go).
It's still taking some getting used to the new Settings layout but a big improvement over the stock GB ROM, and Google Chrome has got to be the best 3rd party browser there is.

Regards36I posted this in a different thread but I feel like posting it here:
FlashTool showed an error too but I ignored it and continue flashing. Voila, the device boots.
Here are very extra careful steps to get it working:
- Start up FlashTool.
- Get into Flashmode.
- Choose the ICS ftf and use these settings:
- After that, flash again with these settings:
- Finally this:
- Unplug device, turn it on.
- Enjoy ICS!
Tested on arc (LT15a). Ignore those errors because they show up after flashing a sin file.
26Small Flashtool update
Flashtool Update to be applied over vers 0.6.9.0 or 0.6.9.1
When applying it, replace any files from your installation with the ones in the update.zip
Once applied, in Help -> About you will have 0.7.0.0 version.
To flash ICS ftf, check the "No Final Verification Check" box. Check this box only for ICS bundles as I don't know how it would behave with GB bundles.
