[Q] Bricked Sony Xperia S - Help a noob out!

Hi all,
The wi-fi connectivity on my Sony Xperia S died a few days ago and it's been irritating me so I decided to root and upgrade to JB to see if that would sort it. Unlocked the bootloader, no problem. Rooted the phone, no problem. But then CWM couldn't identify my device and wouldn't install Recovery. I decided installed Flashtool and flashed a stock kernel, and now it seems like I have bricked the phone.
When I boot I get the Sony splash, and the Fastboot (blue) LED which then goes out leaving just the Sony splash. Pressing the volume keys does nothing during Fastboot. I can do a hard reset and get the three vibrations, but the boot loop is just the same when I power on again. In this state Flashtool says the following:
1/039/2013 14:39:48 - INFO - Device connected in flash mode
11/040/2013 14:40:32 - INFO - Device disconnected
11/040/2013 14:40:37 - ERROR - Drivers need to be installed for connected device.
11/040/2013 14:40:37 - ERROR - You can find them in the drivers folder of Flashtool.
Naturally trying to install the drivers does nothing.
Anyone got any suggestions? I really don't want to have to fork out for a new phone!
Cheers.

Make sure you have closed PCC & SUS.
Then try to flash again.

As cities516 has said, first make sure that all those Sony services and update programs are completely shut (be sure to check the status bar near the time and date too). When you power on your phone, the blue led blinks for some time and then fades away. This blue led does not indicate that you are in fastboot mode. So here is what you must do:-
1) Press and hold the volume up + power button until you get 3 vibrations.
2) DO NOT START THE PHONE.
3) Prepare flashtool to flash the stock ics ftf file
4) When it prompts you to connect your phone, hold the volume down key and connect the USB cable.
5) A green led should light up and the flashing process should begin.
6) Once the flashing is complete, disconnect the phone and turn it on normally.

That's great stuff, thanks. All working now! Although I do feel like a moron, I hadn't realised that the PCC was open in the system tray!

[HARD BRICK] can't get in CWM or turn off sony xperia S LT26i

Hello guys, I have a Xperia S LT26i in the Italian official version of software 6.1.a.2.55 rooted by E-Root v1.0.14 ( locked bootloader )
i wiped battery stats (after wiping data...cache ...all what we can wipe, mount and unmount every thing from the clockworkmod )
i reboot the mobile from the recovery then it crash in the Sony logo it crashes in the sony logo which stays a long time i forced restart by pressing Power button+volume(+) ( tried one viration and three vibrations )
Then the sony logo appeared and won't go away.. I cant boot anything. doesnt respond to hard reset (3 vibrates)
PC wont recognize my phone.
then the same thing happened until nothing displays on the screen and the notification led litghs red lights red when I connect with pc or AC power
then the mobile doesn't turn on or start on recovery mode again and is not recognized by Windows on Flashtool or on the SEUS
i tried to remove/insert battery, waiting to battery drain, charging the mobile without results
what should I do?

hold vol - when phone is powered off and connect usb cable (led should become green), than use flashtool to reflash any stock ROM

When I hold vol(-), connect the phone to pc led become red most times and once in a way it become green for a short time then comeback to red not the time to do a full repair sony update Service or full flash with flashtool i did a successfull repair with the Sony update Service but stopped in the middle and then continued they said that's the phone is repaired successfully but i still have the problem ( won't turn on won't start recovery )

Can you try with another cable? Maybe the one you used is damaged. The phone normaly doesn't exit flashmode when recovery / repair is started.
If this doesn't help give it a try with newest flashtool, get a ftf file for stock fw .55 or any other version you want (would prefer any ICS version). Prepare everything in flashtool until you're told to connect the phone in flashmode than do so ( hold vol(-) ..., or do a soft reset and hold vol (-) with connected usb cable. If your phone enters flashmode (green led), flashtool should start flashing immediately.

[Q] Xperia Arco S stuck at boot logo

I was surfing my fb suddenly it hangs about 2 min so i decided to force restart after restart the phone hangs in the sony logo and wont run for about 10 min or longer i can t do nothing even log in to CWM
i installed FreeXperia Cyanagen Mod 10.1 FXP238 android 4.2.2

attempt to do a hard reset
hold power + volume up + volume down
for approximately >30 seconds
if that fails then use flashtool to reflash the correct firmware for you phone
(flashtool works on Locked nd unlocked bootloader)

That is not possible
Reason: The fact that the phone still turns on with the sony logo means that flashtool will recognize it it FLASH MODE
How to obtain flashmode?
1) charge phone for a little bit
2) Force shutdown using the method i stated above
3)Open flashtool
a. select the thunderbolt icon
b. select the correct ftf for phone
c. when told to enter flashmode on the diagram that flashtool will display
4) with phone OFF (via method above)
a. insert the mini usb into phone WHILE holding down the Volume-Down button.
5) Flashing will start after that

[Q] Xperia Ion Lt28At Bootloop

Hello all.
I hate to post this, but I cannot find an answer anywhere. I've scoured the web for 4 days now, and cannot find an answer.
I have an Lt28at that had Cwm on it. I flashed a rom (which I later found out was a Jellybean rom) and needless to say, I'm in a bootloop.
I power on my phone, it displays the Sony logo, black screen, reboots back to the Sony logo, and so on. Cwm is gone, I've tried powering on while holding back, while holding Volume Down, while holding Volume Up, and even trying Cwm again.
I've read where people talk about flashmode, but I can't seem to get access to this if the Lt28at has it.
There seems to be no working method for me and I think I may have a paperweight.
If anyone happens to know what to do, I'm all ears.
Thanks!

I'm having the exact problem as you with the same phone. The thing is even when you hard reset the phone, when it starts charging again, eventually will start boot looping again and its impossible to put the ION in flashmode that way.
Can you take apart your phone and disconnect the battery from the mainboard? I just bought the tools for that I'm and waiting for them to ship. I don't think I'll have any luck for what I said before though.
What might actually works is charge the battery outside the phone (A ultra pain) and then use SEUS to recover the phone. I have not tried to see if SEUS recognizes my phone when it's boot looping. I will install Windows XP on a spare partition and try that out.
Will subscribe this thread, please help us people!

Dude,
I have bootlooped loads of phones in my time and its easy to sort out.
How to fastboot flash boot img
1) Download from XDA minimal fastboot and ADB drivers – from here http://forum.xda-developers.com/showthread.php?p=42407269
2) Install and run as admistrator – this will open a command window
3) Connect phone in fastboot mode, turn off the device, hold volume up and then connect your usb cable, the phone should he be in fastboot mode
4) In the command window enter the following – fastboot devices – this will show if your phone is connect by returning something like the image attached
5) Now you need to extract the boot img file from the rom you want to install, do this using winzip which can be downloaded from the internet.
6) You then need to open the location of your fastboot file and paste in the boot img file
7) Enter the following command into the command window – fastboot flash boot boot.img
8) Then use the command – fastboot reboot
9) Your phone should now boot up correctly with no error.

Our bootloaders are blocked thanks to AT&T, so that will be impossible! I cant even enter in fastboot mode

I see,
This is going to be tricky then, do either of you have a working recovery?
Is the phone recognised when connected via USB?
Sent from my Xperia S, made awesome by XDA.

It seems like no, just boot loops displaying the sony logo and thats all!

Hmmm,
ok this is the only other thing I got but its pretty hardcore.
First download flashtool and the latest Tft for your phone.
and the process goes like this !
1.open flashtool !*
2.turn off your phone and remove the battery !
3.click on the flash button on the flashtool.
4. at MODE SELECT --- select FLASHMODE --- click OK*
5. FIRMWARE SELECTION --- select SOURCE FOLDER ----- [....] will help u browse to the file location select it then !
6. WIPE ---check both WIPE DATA and WIPE CACHE
7. the click OK
8. After few sec it will ask for usb connection so PUT YOUR BATTERY BACK AND CONNECT YOUR PHONE TO COMPUTER BY PRESSING VOLUME DOWN BUTTON ON THE RIGHT !
9. wait till the process is over
10. unplug your device and wait it will take some time to boot up don't worry just stay calm*
Your phone should then be fully working

Thanks alot for your help! I'm waiting for my tools to ship, i hope to get them by monday and do that, but unplugging the battery isn't the same as hard reseting the device?

EMERGENCY Brick!

hi,
any help is hugely appreciated.
I wiped my phone in recovery with the option to wipe for new custom rom, this worked fine. when i went to install custom rom it failed and then turned itself off. now the phone just gets stuck at the Sony logo. the only way i can turn it off is via the red button in the sim slot.
I am unable to connect to the computer at all, no fastboot. I'm also unable to boot into recovery to restore.
Please help. Hope i haven't ****ed it up beyond fixing
Thanks

Flash a stock ftf with flashtool (in flashmode). You should definitely get into flashmode and fastboot, otherwise there is a problem with your computer.

Funny, I didn't even know there was a red button Holding Volume Up + Power for a few seconds always worked for me, no matter in which state the phone was.

Hi all,
I've exactely the same problem !!!
My phone stuck to Sony logo, and not reconyze on my 3 PC.... before that, usb connexion work fine on all PC, but now.... nothing
I've just POWER + and VOL+ (its power off the phone), i've no led color light
I've try flashboot, but not detect my phone

PS : the red button is in the SIM slot, but i think is same POWER + (VOL+).... its power off the phone

Because you're doing it wrong. Vol+ enters fastboot mode, you have to press Vol- to enter flashmode. Then use Flashtool to restore the firmware.
