Xperia S Fastboot problem

So I was about to root my Xperia S and started reading a guide, it said that I would need to load some files into the phone using fastboot. After a while I figured out how to fastboot and managed to get the popup on my computer once, however, I didn't install it that time and now when I try to fastboot again I get the blue LED on my phone, my computer makes some noises indicating that something unusual have been conected, nothing happens and the phone shows the Sony logo.
Does anybody know how to fix the problem and get the popup on the computer to re apear.
I run a 64 bit windows 7 home premium.
Thanks.

Hi HugNikanor..
When I Unlocked The Bootloader and Was Going To Start Root Process.. I had The Same Problem..
If I remember Correctly It Was a Driver Issue..
In FlashTool Folder There Is Another Folder Called Drivers.. Have U Tried Installing The Fastboot Drivers From There..?

I don't have anything from flashTool. The guide I used is this: AddictiveTips . com and searched for Root xperia S (it's the one that doesn't say gingerbread.) if that can help in any way.

Ok.. You Are Trying To Root Using Fastboot Mode..
I Assume You Have Already Unlocked The Bootloader.. Which Firmware Version You Are Using.. Is It Sony ICS 6.1.A.0.452..?

So for Unlocking Bootloader You have to use fastboot mode.. ok
and after that, for rooting it should be done using flashtool in fastboot mode..
so here is the thing.. Download The Flashtool first And After extracting the files You'll Find a Folder Named Drivers.. first Install The Fastboot Drivers Even To Unlock The Bootloader..

Got that part working now, now just to fix to problem with the phone going out of fastboot mode way to fast. But I think I have seen a guide for that somewhere else.
I will report back after future succes or failures with the project.

Got bootloader unlocked!
Thanks alot for the help with Flashtools. All the guides I found just asumed that you just knew a lot of things which kinda complicated it for me.
Again, Thanks!

No Problem My Friend.. I am Glad I Helped You..!!!

neither fastboot nor flashmode!!!!!
Hi,
I can't connect my phone in flashmode nor in fastboot mode. Whenever i connect it in flashmode/fastboot mode my PC stucks(hangs) and i have to restart it again i have installed all the drivers for all devices but still the problem exists. Any help in this regards???
Also to mention i'm using Windows XP SP3 and flashtool version is 0.9.1.0.
I have also one more issue when i connect my phone to the charger when it is switched off the phone does not charge at all it simply shows me the sony logo and keeps showing it again and again but never charges. In short when my battery is complete i cannot get it back to life due to this problem but thank god that i have installed CWM on my phone.
Thanks for helping i'll also post this in the development section also.

I have no idea to your problem, but I would guess that it have something to do with you using xp, or maybe some damage on your phone.

Hello I have an Xperia S, with bootloader locked and recently installed a ROOM in order to get the 6.A.1.2.55 with root.
Installed from a ZIP from recovery mode following this post:
http://forum.xda-developers.com/show....php?t=2009672
Now when I try to do step 7 (flash kernel and Baseband) Using Flashtool, Im unable to enter to the mode; when the windows prompts me, I turn off the phone, press and hold Vol up connect the USB but nothing happens, only the Sony Logo and then the icon of charging battery, I also tried to turn off the phone while holding Power button + Vol up (at the same time) and get the 3 vibrations, but the same result when I connect, the logo and the charging animations/icon..( no LED of any color or anything)
Im using the latest Flashtool version (0.9.9.0) with the drivers intalled (even though Windows security constantly pestered me about not being able to identify the source and signture) on Windows 7 64 bits..
Thank you..

while the phone is off connect it to pc, open Flashtool in fastboot mod. Flash a stock FW.
If that doesnt work open PC companion it should ask u to repair it if u follow istructions.

@deniel: It doesn't connect neither PC Companion or Flashtool. It doesn't enter in flashmode.

Have you pressed the menu key while connecting phone to computer?

bricked phone have to be OFF(remove battery and put back if necesaary if it's stuck at sony screen), prepare flashtool ftf and follow onscreen instruction and the flashtool will revive the phone.
Or maybe you could show the error msg from flashtool.
you are really bold in trying the untested bootunlocker, this definitely is a hard brick. hope you get out of this one.

I tried with all.

Sorry for asking again: You started FlashTool (v0.9.8.0), clicked on the flash icon, selected "FlashMode", chose a firmware for your Arc S, activated "No final verification", clicked "OK", pressed the back button on the switched off phone WHILE plugging in the USB-Cable? No green LED - nothing? Did it work before?

Sorry if we repeat the same thing, but it must work like this: you hve the phone off and unplugged. You open flashtool, select the flash icon (flashtool), select the FW, and it tell u to plug the device to pc while holdin back button.
Sure u hold the the backbutton while pluggin in? and after have selected the FW ?

You've to select the firmware first before plugging it in.

LT18i
Locked Bootloader
Root access
Had CMW via Xtools, so when I replaced the rom that disapeared!
The problem is that I've forgot to run the 2nd part - device optimization, and now the touchscreen simply doesn't work...
Can't do nothing - USB Debugging is on by default (never forget that I can't touch the phone)
Can't upload another rom via flashtool, the only thing I'm able to do is change the kernel with the 1_lt18i_4.1.B.0.431_kernelDowngrade
If I try to put the uptodate kernel, flashtool stops on "Reading Device Information"
Already try to restore it with Pc companion, but no luck
USB device is detecting LT15 on windows!
This is a total mess, I'm lost, and I've googled and tryed dozens of things all day long.. I'm tyred, exhausted, and my 2 day old ARC S is bricked!!
Can someone point me a way out??
Remember:
- USB debbug of (have no access to activate it)
- CMW disapeared when installed this rom, so have no recovery menu
- Bootloader is locked
- Can't flash rom via flashtool
I'm devastated!!
Thanks in advance,

First charge your phone for a while, then download flashtool and sony xperia s official firmware.
As your phone is switched off, press and hold volume down button and connect it to the pc, green led will turn on,then flash your phone with flashtool.
I always use this method when i brick my xperia s.

Try installing PC Companion or/and Sony update service and maybe you could use one of them to recover and install stock rom again
Or if you can't install it using PCC or sus, try flashtool again, because the two sony programs will install drivers , too

I have exactly the same problem with 2 of my xperia S'es. I really want to fix this issue, because it's beginning to be expensive to buy one after the other. Always going into this without really knowing why.
Neither PC Companion, Sony Update Service, or Emma work to recover....

Z1C won't stay in flashmode

Ok so I've been trying to get flashtool to work with my xperia z1c but I can't get the phone to stay in flashmode. The green led lights briefly and flashtool detects a device in flashmode but after a short time it just drops out of flashmode and boots normally. I originally blamed windows 8.1 but have tried 2 windows 7 machines with the same results. Have tried the Sony z1c drivers package and the latest flashtool drivers - same result. I've searched on Google and found people with the same problem on different xperia devices but has anyone else had the same problem with their z1c? if so has anyone solved it?
Sent from my D5503 using xda app-developers app

So what is the problem? If the phone does not stay long enough in flashmode, try this:
Open flashtool
Click flash, and set up everything (firmware, wipe, etc.)
Now click on flash
After 30 seconds plug in your phone in flashmode.

Happened to me too. I just flashed it before it rebooted, once it starts flashing it wont reboot it'll finish the process. So no worries everything worked out fine.

Thanks for the responses. I'd previously tried to flash an ftf by putting the phone into flashmode first then pressing flash and it always rebooted before the files were prepared so assumed there was something wrong. If you prepare the files first then put the phone into flashmode then all is okay. Thanks again.

how do you boot into flashmode?
the right way is: turn off your device, open flashtools, choose flashmode, choose your ftf you want to flash and wait until finished,
push Vol- and hold it, then plug your device via usb to the computer, then flashtool does its job...

Plz test can you get in flash mode(bootloader mode)..... press and hold the vol down key for a few seconds then connect the usb cable now(For the first time, windows will say installing flash drive driver). Then run flashtool and see if you can flash .ftf firmware, it can also wipe the TA. Make sure you installed PCC or Xperia driver set, and quit PCC before you run flashtool.

Just to clearify:
What exactly did you do with your phone?
Does "stuff" mean you tried to root it?
Which tool did you use? Easy Root Tool?
I can't really see what could go wrong there which could cause a brick...

Used easy root tool. His phone rooted fine and works. The problem is I restored back to stock on my phone and there's a chance I used his TA by accident. Everything was fine until I rebooted the phone and nothing happened. When unplugged, nothing will happen no matter what. When plugged in, the light blinks and that's it.
