Do the drivers work?
Now is the problem updating the firmware?
If that is the problem now, can somebody with an 800i help out, i have the 800x and we don't have such things as MTP

Extracted = installed? Cuz you need to install them on your pc.
Some people have had issues connecting in MTP mode. If you have installed the drivers then try to unmount the sdcard prior to connecting the phone to your pc.

Sorry man now it recognized like a camera dammm android drivers. Any suggestions?

@fast_forious69 i just reread your first post. If you just want root then you should use flashtool to flash the UK generic .184 FW. Then root with gingerbreak and then without doing anything else update OTA to the newest 4.0.A.2.368 (2.3.3). The only way to preserve root when updating is OTA.
Further more you won't be able to root the new firmware if you upgrade without doing the above, unless you also unlock you bootloader. If you just want root there's no need for that imo. You can can always unlock later if you want to do other mods like custom Rom/kernel etc.
Anyway download flashtool and extract it to your desktop. Then install the drivers that comes with the tool (ggsetup.exe). Then download the UK generic .184 FW, extract it and put it in the firmware folder that came with flashtool. Hit x10FlashTool.exe. In the window that opens press flash and choose your FW and then tick 'wipe data' and then ok and just follow the instructions. This will wipe all userdata on the phone apps, bookmarks, sms, saved games states etc.
If you're already on .145 or .184 (2.3.2) then just download gingerbreak and root and then strait after boot update OTA. (I take that you bootloader is locked otherwise don't do any official updates hence it will brick your phone).

Lol then it must be me. Well I'm a guy aswell...
Anyway mate you'll end up with the newest FW update if you follow my guide above (xLoud, themes etc. You won't loose warrenty for using flashtool on the other hand afaik you will when rooting or unlocking bootloader. That can be ereased by unrooting and locking again. Then nobody should know. Atleast i got my device serviced under warrenty that way
Either way you're welcome and you choose what you'll do. If you can't make pc companion work then you'll have the flashtool way to do it...
Regards Dousan...

Hi mate Dousan, i've read your advice but not sure if i'll try to do it the phone is about one month, i've try the firmware way with Pc compainon it says my phone is with the latest update firmware ?!?!?! 2.3.3 wich i confirm in the menu of the Xperia now i'm in a dilema if is really necessary to flash it with the tools you recomend and loose my info contacts, etc... because i cant update the damn phone with sony ericsson OTA backup ! it only backup the bookmarks !!! don't backup my contacts calendar etc.
i've even reinstall Windows XP nothing now is a digital camera (MTP mode) only works acess the phone in MSC mode so only acess the SD card, a bit weird this android phone i've talk with some other guys in another foruns they say windows 7 it's better but my money now is not enough to buy a new pc, just don't no what to do .... maybe take the mobile to the store a see what's better.
by the way is the new things good Xloud new themes etc. ?
thx mate

The xloud is cool, the speakers are nice, loud and crisp now. Good sound. About the themes.. Meh, I only se the background change really, it's not like cm7 theme chooser nor the one I know from HTC. There's some other stuff too, apps and small tweaks. Haven't really gone through the phone and compared.
Well the work lies in flashing with flashtool, then root and then OTA. For me it's no biggie, but then again I've flashed my phones for the last three years now and things has been more complex than this and also easier. All is relative and what is easy for me could be difficult for and vice versa
If you don't feel comfy about doing it then don't. Take it to a certified SE shop and let them do it for you.
Regards Dousan...

Ups....messed up users.
But if bootloader is OPEN/UNLOCKED. Then use flashtool in development section..
This will do this job fine.
If bootloader is LOCKED/CLOSED, then use official update method..if 1st flash unsucsess...then reflash agent.

Going by what I understand, you've downloaded an ota upgrade so, if you haven't unlocked your bootloader, then use the se pc companion to update your firmware, even if it says you're up to date. Or seus to repair the phone.

This can be helpful for anyone whose ROM isn't working. It is directed to noobs who accidentally ruins their custom ROM so they can start over. Also the reason why I'm doing this is because I searched the forums and I could not find a guide that was simple for noobs to understand, which would always work no matter what you did wrong. I've used this method so many times and it has saved me countless times. I thought the least I could do was to share.
I hope I answered your questions.

Why why why do People use uploaded.to links, and feel the need to rehost files to it. Just link directly to the flashtool and use mediafire for anything else.

I understand this reply is far too late but for people in the future:
You cannot upgrade to ICS when your bootloader is unlocked. You can easily lock it again using this small FTF file. When the upgrade with PC companion is complete, you can continiue modifying your phone with custom ROMs etc.

It is very hard for me to know what is causing this problem. Some minor modifications to the flashing procedure can potentially fix it. Try doing it like this: Open FlashTool, drag the FTF-file and drop it in the dialog box. Press ok and wait for the instructions to pop up. When they do, connect the USB-cable FIRST to the phone and after that hold back key while plugging it to the computer. If the battery of the phone is too low I think it can cause problems, try to charge your battery (if possible) and try again. Also make sure to flash the appropriate FTF-file, accordning to your model.

Please help me with this issue

i have bought an Xperia Arc S (LT18i) and it have been performing well and I have been updating it regularly using PC companion
but now the battery is suddenly draining to 0% and when i put into the charger it doesn't take more than 5 minutes to find that it is CHARGED
and when i remove it it doesn't last more than half an hour until the battery low alarm
and i don't know anything about flashing or rooting
does any one know how to fix this ?
and here are the phone software information:
-Android version : 4.0.4
-Baseband version : 8x55A-AAABQOAZM-203028G-77
-Kernel version : 2.6.32.9-perf
[email protected] #1
-Build number : 4.1.B.0.587

Try another battery
Sent from my LT15i using xda app-developers app

Have you tried repairing it with PC companion? But it more than likely is the battery, though they shouldn't go suddenly.
Another option is to take the battery out for an hour or so. Probably best to give this a try first, it doesn't cost any money or mess with any apps

+1 to this...
Repairing via PC Companion, or full flashing via SEUS (SUS now) are your solutions.
If problem persists, then your battery is defected probably.

and what is the best way to make it ?
sorry but i am new to the android OS
and i also experience heating in the upper zone after a short wi-fi usage for 30 miutes or maybe after a long phone call for 15 minutes

i power off my phone at 70-80% to save power and when i start it again it suddenly turns out to be 1%

but this is for those who downgraded from 2.3.4 to 2.3.2
is this problem caused by updating to the 4.1.B.0.587 and if so does downgrading to GB solve this or there is some hope with ICS :crying:
before i updated last time the phone was amazing but now it is doomed

Can you try installing a generic .587 firmware?
You can download it here:
Generic Trade Central Europe 1 (4.0.4) (1254-2716)
https://hotfile.com/dl/167361348/43349db/LT18i_4.1.B.0.587_(1254-2716).ftf.html
You can flash this using Flashtool, if you need any help with it I will write you short and easy to understand instructions.
But first download the Sony Update Service and flash your phone over the official software. It's easy to use and all the instructions are within the software so you dont have to search for them. If the problem doesn't go away with sus repair try to flash a rom with Flashtool.

You can flash this using Flashtool, if you need any help with it I will write you short and easy to understand instructions.
