[Q] downgrade problem with flashtool

Hi guys,
I am new to android os. I wanted to root my phone which has os 2.3.3 installed. I was following this guide http://forum.xda-developers.com/showthread.php?t=1133650. It says first downgrade with flashtool to 2.3.2 then root it then upgrade to 2.3.3. Downloaded 2 firmwares, global versions 2.3.2 .181
First of all when I click flash button in firmware selection screen firmware content tab only shows simlock.ta but in videos which I watched there were many files listed. If I open usb debugging mode and connect my phone flashtool cannot find driver and ask me to choose manually how ever I copied LT15.sin file to loaders folder. If I turn off usb debugging mode (unknown sources are open) and follow screen instructions, flashtool starts flashing and immediately stops and tells me to remove usb, open phone and open unknown sources and usb debugging on. I did not try resetting my phone to factory defaults. I think problem is my computer, running windows 7, and cannot see other file than simlock.ta in flashtool's firmware selection screen firmware content tab. Any help is appreciated.

It should work no problem.
Did you have both PC companion and SEUS installed on your comp? You need both for the drivers.
Some people have trouble using the lastest beta flashtool, so you might want to use the older one (the one before the lastest beta).

Usb Debug mode and unknown sources are open.

Have you tried re-downloading the ftf file you wish to flash?
Because it seems that there's some sort of issue with the file you have.
Also, what version of Flashtool are you using?
Because I've never been prompted to choose what model of handset I have.

I downloaded ftf file from different sources (different sites). I used both 2.9 and 2.8 versions. Does factory reset wipes data I want to try with factory reset and then remove phone's drivers from computer remove companion and seus start from beginning

I had similar problem before, but it was my mistake. I did not put the files in the firmware folder seperetly, I put the whole folder instead and that was wrong. Hope this helps?

I put ftf file directly into firmwares folder.

Stupid question, but did you un-zip the firmware files?

I unziped ftf file (one file) and pasted it directly into firmwarares folder. I think my problem is with java, eventhough I removed and installed java to solve problem it did not work. In flashtool flash section, firmware contents tab there was only simlock.ta is saw. I tried with flashtool 2.4 version and it showd all sin files in firmware content tab. 2.8 and 2.9.1 is not working for me. Tried desktop and laptop pc both have same problem. For people who will face with my problem my advise is using Wotan servers. I flashed 2.3.2 and rooted then OTA upgraded to 2.3.3 with Wotan servers.
Thanks.

Bricked my arc, tried everything. Please help.

Hi 2 all,
I know another thread about a bricked xperia?
Yes I'm sorry.
I've tried 20 different methodes, searched the internet, read a zillion pages but it all didn't help.
This is the case,
I wanted 2 install cm7.2 on the arc. it said lt18i baseband was required so I downloaded and accidently flashed the whole lt18i firmware on my lt15i.
now the phone does nothing. I can still use flashmode but when in fastboot mode I get a need root error.
The phone was unlocked and rooted.
heres the log file:

This is after trying to flash a loader.sin.
Thats where the problem seems to be becouse thats the file that can't be flashed, other files where flashed in an attempt to flash back to lt15i firmware. ( stock lt15i btw )
It states : SEC_LOCK_STATUS="LOCKED"
perhaps thats something.
I flashed my renoir, omnia 2 and sgs2 without problems and I like to do thing myself but I just can't figure this one out.
I've been at it for a total of 8 hours now and realy I've done all I can do before asking for help. ( I hate to do that, this is the first time )
Any ideas are welcome otherwise my gf will probably castrate me for killing her phone and paying service center fees.
Loads of thanks in advance.
Btw I tied all the unbrick methodes and read and tried all "I bricked my xperia" threads here.

have you try with flashtool?

Thank you for your reply.
Yes, I've tried flashtool.
Flashing lt15i stock firmware but the loader.sin can't be flashed and it stops halfway when flashing system.sin.
I've also tried fastboot but I get a "need root" error. The phone was previously unlocked and rooted so I don't understand the error.
Edit : I found that I accidently flashed play loader.sin
In windows devices the phone is named S1boot. Thats play right?
I feel so stupid, is there a fix or a way to force the loader.sin
Sent from my GT-I9100 using XDA Premium App

I think the problem is now flashtool see your phone as lt18 :try to put your lt15 bin files included loader. sin inside the lt18 folder and try to reflash....

Thanks for reply, thats a great idea! I was so stuck. But in lt18i folder? How do you mean? What folder. Thanks again!

did not work for me...
it simply doesn't see the phone.
friend of mine tried to flash with ftf files (because yesterday we stuck with SONY LOG) BUT somehow he flashed "mk16i_4.1.B.0.431_ready to root" and now device is shown is EXPERIA PRO (mk16i) .....
we can't flash any other ftf files e.g. "LT18i_4.1.B.0.587_(1254-2184))" or "lt18i_4.1.B.0.431_ready to root" - phone gets into flashmode but if we try to flash it shows ERROR and stops flushing.
Any ideas?...
p.s. Settled down activated finally.

Press and hold the volume up + power combination until you get 3 vibrations. Then try connecting your phone in flash mode and flash the latest firmware using Flashtool.

Can you please describe the problem in detail? If you're having driver problems, then go to the drivers directory in Flashtool's folder and open the driver installation exe file and install the drivers for xperia s.

Is your boot loader unlocked? If yes, then you should be able to connect your phone in fastboot and flash a custom kernel so that you can access cwm and flash a rom from your internal storage.
If your boot loader isn't unlocked, then download Sony's official software called Sony Update Service and do a re-install of the phone's software. Installing SUS should take care of all the driver problems too.

Device connected with USB debugging off

my xperia t2 ultra dual is with bootloader unlocked. i want flash the rom stock in flashtools, but the debug is not identified when connected in flash mode. Someone Know like solve this problem?

For connecting in flashtool you have to switch off your phone and press volume down for flashmode and volume up for fastboot and connect USB and se confirmation on flashtool for connecting. I think it will helpfull for u..

I did that before of to open the posts. the problem is that, the flash tools not is identifying like debugging on. the program shows this message "For 2011 devices line, be sure you are not in MTP mode", but i tried of every forms of connection usb, with debugging on, even so i didn't have success.
the smartphone is with rom CM11, with recovery clockworkmod and bootloader unlocked. The flashtools program, just identifies like debugging on, when my phone is connected . when i do try connect in flash mode, the program shows this messages "For 2011 devices line, be sure you are not in MTP mode" and " Device connected with USB debugging off".
i would of one original kernel, without recovery. if someone has. send me please.
