[Q] recovery mode???

i've tried time and time again to get this thing (TL) into recovery mode holding the volume up while powering in many different ways but i just cant get it into recovery, any special trick here???
Have you installed recovery yet? I think not if you have the TL as you need to unlock the boot loader to do that

In case you do have recovery, it's a matter of timing.
On my T with the advanced stock kernel installed, it works like this: Turn on *vibe* Sony Logo *vibe* LED turns purple -> now hold Vol-Up. It will then boot into recovery, eventually.

[Q] Xperia Z possible brick

After searching around I couldn't find anything related so here's my problem.
After succesfully unlocking the bootloader of my Xperia Z it continues to work fine.
It prompted the initial startup screen (enter language, account info ect.)
I turned my device off and on... this is where the problem starts..
This is what i get
Sony brand logo>
Xperia brand logo>
5 repeated cloud animation of xperia logo and at the last one it stalls, Phone reboot and back to 0.
This goes on repeatedly until a hard poweroff or complete discharge ( I suppose)
So I know im kinda screwed, is relocking the bootloader any option? Contacting Sony atm for some sort of software replacement/flash anything..
Cheers, Geert
Try the safe mode,keep pressing vol down with power until the phone boot completely.
If the phone boot to safe mode than do a factory reset.

Welcome to XDA
you should go to the recovery thread in my signature. Read the first 2 posts.
Hope you recover your phone.
Hi everyone !
I have the same problem as GeertNool. My Xperia is stuck in the same loop. I have tried everything.
- Flashboot : stuck at 0% when i try to flash
- Pc Companion and SEUS = dead ends
- Safe mode : cant make it work
I read the recovery thread. It seems that the Kernel is malfunctioning but i dont understand what should be my next move. Am i supposed to let the phone reboot endlessly untill eventually the battery dies ?
Thanks a lot for your precious answers.

Yes.
When the battery dies the phone should reset itself.
After the loops end plug into a charger, not pc for now.
You should get a red led indicating low battery level charging is working.
After the red led you may get Sony boot screen or bootloops.
If you get Sony and then the charging battery icon, then charge to over 50%. Then use pc companion or flashtool to restore.
If you get bootloops then read my 2nd post from the recovery thread in my signature for bootloop tricks.
Please let me know if it works. I am looking to add the Xperia Z to my recovery guide.
If there are any questions about my guide please ask in that thread.
Thanks

Try this: hold power and VolUp for about 15 seconds. The device should vibrate 3 times in a row. It should now be off. Don't plug it in anywhere.
Download the correct flashtool beta for xperia z http://forum.xda-developers.com/showthread.php?t=2162907
Download a known-to-work firmware ftf
Put it into C:\Flashtool\Firmwares
Open flashtool (flashtool64 if you run 64bit Windows)
Chose Flash (flash arrow button)
Chose the ftf you downloaded
Enable "Wipe: Data, Cache, Appslog"
Click flash
A new window opens with a "press back button" animation
Now plug in the device while ONLY holding VolDown. Only VolDown, no Power. The LED should turn green.
Don't interrupt the flashing process. It will take a while.

i will try to flash it using flashtool. thanks for your help mate
had the same problem and i managed to fix it just showing sony sign by installing the sony update programme on the sony update website
all you do is put phone into flashboot mode.
on mine i had to hold up and power button untill it vibrates 3 times then press down volume button to get it into flashboot mode
takes a few atempts but it worked.
takes around 20 mins to download then install another 10.
i couldnt get flashtool to flash firmware as my phone is locked on 3 mobile firmware locked bootloader
i hope this helps you
update:
schaggo method works. i can breath now. thanks to @gm007
This worked great for unbricking mine !!
P.S. don't waste time for Sony's Emma flash, they do not send login credentials in real time, site says they do manual user validation ...

I have the same issue here, the phone suddenly dead. Charge it using AC adaptor and wall socket and the red led flashs for about 2 hours, the orange LED never turns on. Try your advice and got this:
1) Vol up + Power not work (no vibration, nothing)
2) Flash with flashtool 0.9.10.2 beta6 with no lucky, indicated "device disconnected" after animation gone.
3) regress to flashtool 0.9.10.1, device connected and then stuck at "flashing data.....", the progress bar stay at 0% and then nothing.
P.S. bootloader is still locked but phone is ROOTED so I'm affraid it's out of warranty. Just got the phone as a birthday gift from my wife yesterday! She'd kill me if she knows that.
Update:
1) Power + Vol Up works now. The sequence does matter, I found I have to press the Power button first and then Vol Up, it dosen't work vise versa.
2) flashing still doesn't work for me. And I noticed that the LED turn green and then turn off immediately. I'm not sure if that is the cause. I'm sure when in fastboot mode (connect to USB port when pressing Vol Up), the LED turn blue and stay blue. Is my flash mode corrupted?? That's really bad!

Try sony update service or remove flashtool and install again and use another firmware(maybe the first one is corrupted).

Returning to stock
Hey guys,
I've flashed [ROM][JB 4.2.2][CM10.1][AOKP-MR1][PananoidAndroid 3.15] PAC v22.1.1 - Update: 0508 from http://forum.xda-developers.com/showthread.php?t=2208249&page=65. It's working, but I'd like to try another ROM, specifically Xperia Z Revolution™ from http://forum.xda-developers.com/showthread.php?t=2175903. This requires to install stock 10.1.A.1.434 firstly So I downloaded C6603_10.1.A.1.434_Generic DE, NL, world. Flashing with Flashtools 0.9.10.1 always stucks at 0%.
BL unlocked. Does anyone have any idea how to get stock 434 in the phone? Originally there were older one 10.1.A.1.340, if it's somehow important to know...

Phone bricked

Hey guys.. i think i have bricked my phone
I have the c6602 model and have a unlockable bootloader but left it locked. I have rooted it using goroh_kuns method
http://forum.xda-developers.com/showthread.php?t=2186368
then put CWM for locked bootloaders on it using this
http://forum.xda-developers.com/showthread.php?t=2187363
then flashed this stock based kernel ROM through CWM without wiping the old one
http://forum.xda-developers.com/showthread.php?t=2175903
but now my phone starts up, and reboots automatically, resulting in a loop. I can not go into the CWM recovery anymore because you have to do it through pc everytime while your phone is on.
Personally i think its Superuser from the previous rom and SuperSU from the new rom mixing up and resulting in the loop boot
Can somebody help please..?

Did you try to enter to CWM recovery by pressing volume key while booting to see if the recovery is working
yes it does not work, the led becomes blue after holding power + volume up it vibrates thrice x 2 then i continue volume up and the led turns blue but nothing really happens, i think its the download mode?

If you have the blue led working this means that it has the fastboot mod working - press VOLUME UP + PLUG INTO PC(not power)
try to switch off the device then press the VOLUME DOWN button while connecting to pc = flash mod
If you have one of theese working you can always repair your device

[Q] Phone soft-bricked, please help!

I flashed CM 10.2 using CWM on my Xperia TL (LT30AT) and when I rebooted it, the phone wouldn't turn on. The screen stays black, although the orange LED comes on when I plug it in. When I press the power button if it's unplugged, the LED flashes orange twice and turns off. I tried using Flashtool to flash the stock ftf, but it doesn't stay in flashmode long enough for it to flash it completely. Please help, I need this phone!

have you unlocked the bootloader?
If not then repair with pccompanion.
If you have flash a stock kernel first then flash with a stock ftf in flashtool.

My PC won't recognize it, and it won't stay in flashmode long enough to flash a stock kernel.
Now it's looping the Sony startup screen..
The bootloader is locked.
Then that's your problem,
You cannot flash cm on a locked bootloader.
Charge the phone for 24 hours then use pccompanion with the correct drivers to repair it

Hey,
Were you able to solve this issue. I have the same issue and I was trying to load pacman ROM on to my phone. The phone vibrates sometimes when pressing the power button. On long press of power + vol up, it does 3 vibrations and thats all. I tried "Emma" (the Sony flashtool) and it recognized my phone. But, the ATT model of xperia TL's bootloader cannot be unlocked and hence was not able to use the flashtool. the PC companion too detects the phone, but when i try to repair, it starts the process but says there is not update for the model. Is there any other manual way in which this issue can be resolved. Any thoughts would be much appreciated.
Thanks.
Use sony update service

Actually, the problem could be the same as for the Xperia T.. the cm 10.2 boot.img are corrupt.. I had the problem yesterday and needed to flash a boot.img from 11. november out of a nightly to get the 10.2 RC1 working.. You should try with fastboot. On an Xperia T you should force a shutdown with power button and volume up button pressed until it vibrates 3 times, and the boot into fastboot. I got it working but was not convinced with 10.2 RC1 cm.. I had the same bug as in an 10.1.3 stable : freezes when tilting the screen in graphical apps..

Xperia T lt30p Not able to enter in flash or fastboot mode

Its embarrassing because i've been using android for 2 years. I rooted my phone unlocked bootloader & used many custom & stockbased custom roms. I was flashing a mod, mistakenly i chose wrong file. It wiped my system. then I rebooted & saw sony logo after that black screen. No led light. No charging. I tried pressing power button+Vol up key. It responds & reboots & again comes sony logo & black screen. I tried getting it in flashmode & fastboot mode. But its unresponsive. I think I should turn off my phone first then boot into fastboot. But how can i turn off? it only reboots. Please help.
Last Rom Used: Ultimate BlackXT v1
