[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.

Wait if you are just rooting you don't need to do that. What model is your phone?

Check if your bootloader isn't locked and you have unlock it first.
Rooting methods like Zerg rush not working on 2.3.4 software.

Thanks, but i havent figured out exactly what my bootloader is.
I have the Xperia PLAY R800x and gingerbread 2.3.3.
I just tried Flashtool and that didnt work either because my phone wont go into

You have to flash a previous firmware, since November 2011 update, zergRush xploit doesn't work

Ok only thing is i need proper instructions cause the videos for that are messed up and old.
I also need a link for the previos firmware.
But last time i triedd i could only go into flashmode.

I need good instructions

What I would do is flash back but at first check if your fastboot is actually not working.
Turn off the device and check it, take out the battery and put it back in then hold search button and plug in usb if you have a blue light then fastboot is ok.
You also need Android ADB drivers which you need to have the Android SDK to get them or if you have flashtool there is a drivers folder which is the simplest method to install ADB bridge.
Then using flashtool (if it worked) flashed the DoomLord Kernel, if it says you have no permission to do so then you need to unlock your bootloader.

Ok I will most defenetly install the adb drivers once I know where to get them. How do I know if I have the android sdk?
I have the flashtool but when I downloaded it it came with 3 programs and no folders.
Can you give me the link to the folders or to the flashtool that has the folders with it when you install it?
I also need the link to the doom kernel which I might have and instructions on how to flash it.

You should first download flashtool. Then use flashtool to flash the verizon firmware. I will provide a link. Then enter flashmode by turning your phone off completely. Hold the back button, and plug the usb in the computer and then into the phone while still holding the back button. A green light should appear on the top. Then flash the firmware and there. Then use superoneclick to root

Luckily you have flashtool so you do not need the Android Sdk. There should be a drivers folder in your flashtool and an executable inside that will install like a normal program. This contains all the drivers you will ever need.
On every time it installs one it will prompt you to install or not install jusf click install and you will be asked this about 20 times for each driver.

If I remember correctly, the xperia play 4g was R800at and not R800x. Well anyway you have to download the firmware for your phone. Then place it in the firmware folder inside the flashtool folder. This should be the correct firmware for your phone. http://www.mediafire.com/?qqvtl484nlz3gq0 just place the ftf in the firmware folder. Start flashtool, click flash, then choose flashmode. Select the firmware.There should be instructions on how to plug in your phone and there it should flash.

I haven't had an in depth look, but I'm guessing you could just extract the ftf and .sin then push them to the phone unsure if other steps are needed.

will be great to have,or if you have a solution!

If your ftf files are valid you should check your language&regional settings it should be U.K or something if you are coming from another regional settings.
After that you can flah via flashtool.

Thanx but...
i changed that but no go.If you mean it to change on PC!?

Sorry been busy don't have time to do it, but try extracting the .ftf then use flashtool to to extract the .sin and finally mount the yaffs2 files and just push them to the phone. Then in cwm make sure you run fix permissions.

[Q] Arc S got stucked on sony logo

Hello everybody,
Let me tell you what happened with my arc s. Few days ago i tried to install Xperia Ice Bean 4.2 on my Xperia Arc S. I was successful to do so. My cell phone was far more better than ICS 4.0.3. Yesterday i found new version of Ice Bean 4.3 and i tried to install it.What i did was i just followed the update process posted on http://forum.xda-developers.com/showthread.php?t=1863036&page=2 . I downloaded the ROM file copied it to my SD and installed the ROM. It said installation was complete. And i tried to reboot, and then i got stucked with sony logo. I totally don't know what to do as my phone doesn't gets detected by PC. My arc is locked one. So if anyone of you know the fix for this problem, please help me.

N always remember to take backup in CWM before flashing anything..

I have done all that you listed above but my phone doesn't go past the connection step. It sees my connected phone in fastboot but nothing else happens.
btw my phone is only showing the Sony Logo after a failed attempt to load a custom Rom.
phone is a Xepira Arc S. was Rooted and Unlocked Bootloader...
please help.

When screen states device connected in flashmode ,Click the lightning icon again and you'll come back to earlier page.Now reclick No verification and press OK again.The unplug pluggin visual will pop up again but this time do not do anything and let it follow thru.It will start flashing automatically.

My ZL bricked.. please help

it's been just two days since I got my new ZL
Cause: It happened when I changed 'build.prob' and saved via Root Explorer.
As soon as I saved the file, phone automatically rebooted and fell into boot loop.
I believe something is wrong with permission (for build.prob)
My ZL
does not have unlocked bootloader
thus , does not have recovery to fix permission.
ADM does not work since usb debugging was turned off
is rooted
is able to go into FASTBOOT but can't flash since it's not unlocked bootloader.
I believe it can be fixed by changing permission for 'build.prop' to 644
spent like 3 hours til 6 am here and no luck.
Is there is any method I can fix permission? recover or do factory reset?
I was following 'MUST DO' list for ZL. it happened when I tried to remove navibar.
Any comment will be appreciated.

Run into same problem. So volume down+usb to PC when flash?

Install flashtool on your pc and there is a 'driver' folder under 'flashtool'
Install the driver file select xperia z and flashtool driver.
Then launch flashtool and flash ftf file.
It will tell you how to enter flashmode.
