Hi, i need some help.
My LT15i is now unlocked, rooted and flashed with cynogenmod 7.
I want to install the official ICS.
So the only thing i have to do is put the 4.1.B.0.431 Generic global world file on my SDcard and install via recovery?
Firmware: 2.3.7
ROM: Cyanogenmod 7.1.0.1 xperia arc LT15i
Kernel:2.6.32.9-FXP [email protected] #4
Or do i have to do more?
Please help cause my phone is now very unstable.
Thanks.
No, for that you need to use flashtool.

.ftf files need to be flashed by Flashtool.
Recovery is good for flashing ROMs but it can't change the kernel or the baseband.
The .ftf contains all this stuff so you just need to flash it with Flashtool.
And just FYI, .img is flashed using fastboot.
Cheers!

Thanks for the clear answer!
I now understand that a .ftf contains also kernel and baseband.
I flashed the file and till now everything seems to be ok.
Installing app-, contacts-, sms- backup and again ready to go.
Thanks again

Hey guys, my phone is currently at 4.0.2.A.0.62 and it is boot loader unlocked. But I have complete no idea how to root my phone. And after I root, I would like to have my phone's UI look like the Ice Cream Sandwich look, but not the actual firmware, because I heard that Xperia Arc cannot handle ICS from the official sony ericsson website. So if anyone of you guys can help. It would be very helpful. Cheers
You can't use tools to root .62 firmware coz sony did something not being able to root it.. As you mentioned that your bootloader is unlocked why don't you flash a custom kernel like Doomkernel and a smooth rom like Arconium and it'll do wonders for you.. Then you can install themes to get the ICS look.... Because, i have done all of these and presently using this setup!

Hey yeah thanks mate. But where can I get the kernel from, can you post the link? And I've got the flash tool software, so do I just flash the kernel from there? Cheers

Above s the kernel link, download both the kernel and the libraries.. Yes you can flash kernel using flashtool..Copy the .img file to pc, Get into fastboot mode by switching off the mobil, then press the menu button and connect to pc.. Flashtool will say that device connected in fastboot mode.. Now go to flash option and select fastboot mode, from the toolbox select kernel to flash and point to the img file.. The kernel will be flashed.. Now go into recovery and flash the libraries you downloaded from the kernel thread or else wi fi wont work! Get it?

So I've been trying to root my Arc for a while now.
Tried downgrading to GB, rooting and upgrading back. Didn't work.
Tried flashing a 4.1.A.0.562 FW, using 3 different files: LT15i 4.1.A.0.562.ftf - Flashtool failed at the start.
LT18 4.1.A.0.562 Generic & Nordic - Both caused my Arc to stuck on Sony screen, or loop.
I figured I might need a proper 4.1.A.0.562.ftf for LT15i, but can't seem to find any.
Any help?
I flashed the .562 LT15i on my LT18i make sure you are on ICS and Wipe do not exclude your Kernel. Use the flash tool tick Wipe Data, Wipe Cache and leave the rest untouched. Use No Final verification
What do you mean by "use no final verification"? How do I do that?
Which version of Flashtool are you using?

Thanks. Finally managed to root it.
Downloaded a Lt18 4.1.A.0.562 UK firmware. Flashed it with the settings like you described, then rooted with DoomLord's rooting toolkit.

If you want to install custom rom, you have to unlock bootloader and root the mobile.
Unlocking bootloader will void the warranty.
Steps to be followed to install custom ROM.
Warning - It clears all the user data (msgs, contacts, etc.,). Please take backup.
1. Unlock Bootlaoder.
2. Root mobile.
3. Download fastboot and flashtool and install flashtool.
4. Install requires baseband using flashtool.
5. Download cyanogen mod.
6. Flash the kernel using fastboot.
7. Flash the ROM using CWM.
If anything goes wrong you should download the Generic ROM (.ftf) and flash the ROM using flashtool.
Search in this ROM for each step. Then you will get all the details.
Hit "Thanks" if anyone helped you. :good:

What have you done before? Have you tried to install a custom rom? But that's no problem, first you've to reflash the firmware, by doing this:
Download flashtool (can be found in dev section)
Download the firmware .587 (http://forum.xda-developers.com/showpost.php?p=24467321&postcount=1)
Install flashtool
Put the downloaded ftf file into the firmware folder of flashtool (C:\Flashtool\firmwares)
Then start flashtool, click at the flash button, choose the firmware, check "No final verification" and click on Ok
Follow the instructions
If the firmware have been successfully flashed, turn your phone on
Optional: Then you can root it again and install CWM if you want
When you've got a question, just post it :good:
can you please advice how do i update my firmware from .431 to .587?
one post above yours - there is a solution for intall .587

Hi guys!
I have an Arc S (Lt18i) stuck on Gingerbread and I would like to have the latest stock ICS version, which I think is 4.0.4.
I understand I have to use a program called flashtool.
Will I be able to flash the ROM using flashtool if my phone isn't rooted and the bootloader is locked?
And could someone point me to a link to download the ROM?
Thank you very much.

No you cant flash kernels whrn your bootloader is locked...
You must unlock & root your mobile 1st.
You can only flash firmware(ftf) files with above configuration...
Press thnx if I helped.

Locked bootloader can flash stock kernel, you cannot flash custom kernel. Locked bootloader does not mean cannot flash kernel.

Ok thank you very much! so I've looked and just to clarify:
I put this file in the "firmwares" folder in c:\flashtool,
press the lightning icon and choose Flashmode,
select Wipe User Data,Wipe Cache and No Final Verification Check
Will I loose all my apps? and if so, can I do it without wiping user data?

Flashing via Flashtool will always wipe data. Unless you have a nandroid backup, it's not possible to keep apps and their data.

Wrong. Flashtool does not require unlock or root to flash stock firmware/kernel or any other part of the FTF file.

At the moment, stock kernels can only be installed via FTF file.
