If you spent those 3-4 hours on XDA instead of scouring the net, you'd be a much wiser person. LOL!
But frankly, you searched for so long but didn't find anything? Unbelievable! Perhaps you should brush up your googling skills. :-\

see dude ill give u a step by step guide..
Download DRIVERS & Flastools from http://forum.xda-developers.com/showthread.php?t=1653188 (Under DRIVERS & SOFTWARES Title)
the easy but little long way....
1) back up contacts(click menu,click backup contacts, then click memory card) to sd and save the file(which will be in sd/system/PIM folder to pc)
2) copy/paste all images, videos, music, etc to pc .
3) download Generic Trade Central Europe 1 (2.3.4) (1254-2716) from here >> http://forum.android.com.pl/f308/oprogramowanie-dla-sony-ericsson-xperiaa-arc-s-147007/
4) download atleast flashtool Version 0.6.8.0 (google it or search threads)
5) download doomlord_v4_root-zergrush-busybox-su (for root) ( same google it or search threads)
6) open flashtools and drag Generic Trade Central Europe 1 (2.3.4) (1254-2716) ftf file in flashtools. A pop-up will come telling u same as i am telling u in 7th step .
7) switch off your phone, hold the “Back” key (key at the bottom left on your Arc s), and then connect the USB cable to your phone. Remember you’ve to hold the “Back” key while connecting the USB cable to phone.
Once the phone gets connected — Flashtool will automatically start the flashing process. (once the process starts u can unhold the back key)
Keep an eye on the Flashtool’s screen.
And once the process gets finished, disconnect your phone from PC and switch it ON.
Don’t freak if it takes longer to boot (that’s normal) as the phone has to build the cache again after flashing.
once you get .42 gingerbread, enable usb debugging and unknown sources from in phone settings, connect phone to pc via usb and run doomlord_v4_root-zergrush-busybox-su(runme batch file)
your phone might restart, disconnect from pc and then check you will have root.... then update your phone via wi-fi as u will recieve .62 update, once its updated first boot will take time. Then you will still have root in .62 firmware of gingerbread
Shew!!

well it was to download first 4.0.2.A.0.42 Generic Trade Central Europe 1 (2.3.4) (1254-2716) not .62, u have to root with my steps told being in .42 then update via wi-fi to .62 .......... (u will find .42 little down in the list on that website)
i told u in my steps on the earlier post that "once you get .42 gingerbread" then enable usb debugging and unknown sources from in phone settings, connect phone to pc via usb and run doomlord_v4_root-zergrush-busybox-su(runme batch file)
and so on ..... maybe you missed it, its ok if u didn't do it this way and instead downloaded the .62 ftf file
just do it this time correctly n it should work....

[Q] Went from Gingerbread to ICS 4.0.4 -Issues! Help?

Hey guys,
Been a long time creeper of these forums, haven't gotten myself stumped until now so I figured I would request some help from the guru's. And yes, before making this thread, I have been searching for about 3 days straight trying everything I possibly can.
Current settings/specs:
Phone: Xperia Arc LT15i
Android Version: 4.0.4
Kernal version: 2.6.32.9-perf
[email protected] #1
Build number: 4.1.B.0.431
Bootloader is not unlocked
CWM not installed
Problem:
I went from an old custom rooted Gingerbread ROM directly to the new ICS 4.0.4 (4.1.B.0.431) using the latest version of Flashtool. Now that I have done that I am finding it impossible to get CWM installed, unlock my bootloader, root, or really do anything I need to get this done.
What I wanna do:
Ultimately my goal was to get this ROM installed MooDeD ICS 90.2 LRS Edition! If I cannot do that I at least would like to find a way to either downgrade to an older FW/Kernel and start "fresh" so I can take the proper steps to get that ROM installed OR at least find a way to root this version so I can get Titanium Backup working and re-install all of my apps.
While I am not a total noob when it comes to this stuff (I've modded several other phones and gotten ICS running on my HP Touchpad) I am thinking I am in over my head here. If you guys need anymore information from me please lemme know!
Thanks a ton everyone.

Hmm, so your main issue is that you can't root your phone.
What you need to do is download the 4.0.3 kernel (.562) which is rootable using DooMLorD's Rooting Toolkit. The 4.0.4 kernel is not rootable.
Either download the entire fw (.562) and flash just the kernel excluding everything else in Flashtool or just download the kernel alone. Root it and once that's done, flash back the 4.0.4 kernel. (You've already got it in the .431 fw. Just make sure you exclude everything other than the kernel). That's about it.
Once you've got root, you can install CWM by installing pvyParts's Xperia CWM Auto-Installer from the market. Titanium Backup should now work since you've got root.
And as long as you've not got a branded device, you can unlock your bootloader at any time via the official Sony route.

Thanks for the reply.
I tried doing what you recommended (flashing just the kernel for .562) and I get the following error:

Is that because I am just using a bad .ftf file, or is it something else? Is there a particular download you would recommend (whether it would be just the kernel or the whole fw). Something I did notice when I'm doing the Firmware Selection in Flashtool under 'branding' it just shows up as a bunch of squares, not sure if that means anything.
Thanks again!

Make sure you tick/check the No Final Verification box.

Double checked and it was ticked. Basically everything is ticked except for 'exclude kernel'.

dude only tick no verification box..untick everything else

Even if I am just trying to just downgrade the kernel alone?

So I have been playing with a few options and can't seem to get past this error, does anyone have any suggestions as to what should/shouldn't be checked if I only want to flash the kernel, or do I have to flash the whole FW?

You have a problem with sin header.
I suspect the file was damaged ( maybe in the download) or the bundle creation wasn't done successfully.

I have tried downloading a few different ftf files but they all seem to do it. I'm currently downloading one called LT18_4.1.A.0.562_NCB, was debating trying that one. I assume it doesn't matter that I have a LT15i (based off what I have read). Do you have any suggestions?
Thanks again

Hey everyone,
So some great news, I got it rooted! Wouldn't have been able to do it without all the above help.
In case anyone ever has a similar problem I will explain. What I ended up doing was downloaded a different .ftf file, the exact one was called 'LT18_4.1.A.0.562_NCB.ftf'. I then flashed just the kernel (unchecked wipe data and cache, excluded everything but kernel, and of course checked no final verification)
Once I did that basically all I did was follow the steps in this video.
After I did that and had it rooted (yay!) I did what xtacy mentioned and installed pvyParts's Xperia CWM Auto-Installer from the market to get CWM running, and that's it!
I assume now I am good to go and install MooDeD ICS 90.2?
Once again, thanks you guys!

Hi !
Glad you got it working though i visit this topic for the first time. Wish i could help sooner.
Anyway, i did also the same by flashing an Arc S ftf (LT18i) on the Arc (LT15i).
So far i didn't experience any serious issues except maybe the fact sometimes, my phone requires me to reboot itself. It happens once every 2-3 weeks on average. It's confusing at first but i got used to it.
Actually i also use an LT18i as workphone and i don't have the same reboot message as for the LT15i.
I don't know if the following can help but i would discourage to upgrade to .431 and remain in .562 if you like modding your phone. When I flashed to .431, the Xperia S Power Widget i had modded to .562 didn't work properly and brought some notification bar vanishing symptoms for some 20 seconds or so. This, for me, was unacceptable. Therefore i came back to 4.0.3 in .562 for both devices.
If this can help any reader ...

Install Miui on xperia arc Lt15i locked bootloader

Hey guys,
So i have been rounding the forum for weeks and i still cant manage to install MIUI on my xperia the thing is its has lockedbootloader and i have no ideia how to root it and CWM on it.
I have found some threads but most of them with broken english and i just dont get it.
I want to change my rom badly since i find xperia stock rom horrid.
Big hug

Here are the steps to rooting your phone and installing CWM
1. Download Flashtool and flash a rootable arc or arc s rom (if you're using arc s, here's one). You can usethis tutorial to help
2. Download and extract this
3. Put your phone on debugging mode and connect it to your computer
4. Run the 'runme.bat' from the extracted folder
5. Download x-Parts from google play and it'll install CWM on your phone.
Done! :highfive:

Thanks alot! i still cant find a rootable arc rom i'm using the normal one arc LT15-i

Okays that's fine. Flash a normal arc Lt15i rom, and then flash this, and then root it, and then flash this
You should be fine now

I guess thats no problem flashing with lt18i kernel?
(sorry for my ignorance noob here)

Ok so now the thing is i encountered a lt15i root ready rom i began flashing and it gets stuck at 14%

This is Damn Frustrating ... CAN'T UPDATE VIA PC COMP/ SEUS

I don't understand what is wrong. First of all I don't seem to understand actually what model I brought?! I am damn sure i brought a Xperia SL. But there is no specific forum for SL in XDA. When i browsed around, i found out The Xperia S has model number as LT26 and has two models LT26i and LT26a, and mine is LT26i ! But in settings it shows MODEL Number as LT26ii (double i ??? )
So can someone tell me what Sony product I have actually brought?
then, when i connect to PC Companion, it says a new update available - 6.1.A.2.55 [Mine is 6.1.A.2.45].
And when I do all the process as stated by it says
"UNABLE TO DOWNLOAD YOUR PHONE SOFTWARE. PLEASE CHECK YOUR INTERNET CONNECTION AND TRY AGAIN"
Even though my internet connection is perfectly working.
Then I tried to update using SEUS.. I followed all steps .. Switch off phone, wait 30 secs, hold back button and connect usb, after everything it displays "THE PRODUCT COULD NOT BE IDENTIFIED".. what the hell ?!
I have attached images of both the errors in the attachments. Please help me out.

LT26ii is an SL
Its effectively the same software etc as an S just yours runs @ 1.7ghz
Not sure why pc companion etc won't work. We use flashtool on here. But you'd have to see if they're are ftf files available for the firmware update you want

Nopes. Its good as new.:good:

Ftf files we use for Flashtool (firmware flasher for Sony Devices) if u r unable to update via Pcc or Update Service u should use it. And your problem about internet connection error is common for updating sony. Its from sony server to reduce overload you can try again after day or two it will start work. Had the same problem wen I was updating to 4.0.4 from GB.
