[Q] Xperia T Boot-Loop after Update

Heyho!
I searched almost the whole day & web to find a solution for my problem, and you are my last instance.
My 1 day old Xperia T got into a Boot-Loop, and only the Sony-Logo shows up after starting the phone.
Previous procedure:
I installed the Sony PC Companion 2.1 and updated to 7.0.A.3.195, after this the phone went into the loop.
Now i can't flash any other software because USB-Debugging is off, and i didn't root the phone yet.
I tried to flash back to LT30p_7.0.A.1.303_Generic DE (found it here) but without Debugging = no flash.
Do you have any idea how i can flash or use any other FW without Debugging or Root?
Flashmode and Fastboot mode work in Xperia Flasher!

If you can stand loosing your data you could try a factory reset via recovery.
Info on how to access recovery menu is in the all-in-one thread.
If I helped, hit Thanks!

If you tried this via the official PCCompanion you could always take it back to the shop.
But i do suggest the following
1) Uninstalling pccomapnion
2) Redownload and install PCCompanion
3) Repair phone via PCComapnion. (You do not need USB debbuging for this)

I can't even enter Recovery because it immediately restarts after the Sony Logo!

The PCCompanion doesn't even recognize the phone because it always restarts. There are only 2 modes: loop or off.
I will return this brick to the shop, thank you for the proposals!

Your phone needs to be turned off for PCCompanion to flash it....Just go through the steps to update software and choose repair

I know what you mean, but when i plug in the USB-cable, the phone automatically turns on.
The menu is like this: SEARCH -> CONNECT (i plug in the cable) -> RECOGNITION -> at this point the phone is on for a few seconds
but it turns off and aborts the update!
This error appears: "PC Companion could not connect to the phone... please read the document troubleshooting".
But no point in this document helps me. There are only proposals like:
-use another USB port
- turn the phone off and on again
- Use another USB-cable
Seems like Sony bricked it with it's own software

Take it back to the shop then

Did you try :
while device is power ON
Volume Up + POWER (for 10 seconds) -> resets the battery, its like removing the battery and putting it back in [device will vibrate once]
Volume Up + POWER (for additional 5 seconds, total 15 seconds) -> will power off hard, device will power down [device will vibrate thrice]

You don't have to. You have to put the device in fastboot or flashmode which you reach by holding either vol-up or vol-down BEFORE respectively WHILE hooking the phone up to your pc.
But as greg said, undplug and completely power off your device and put it aside. Then start PC Companion and chose repair. PC Companion will then guide you through the steps necessary to get your phone to a state where it can be reflashed.
because it always restarts. There are only 2 modes: loop or off.

Not true, it does not restart by itself in either flashmode nor fastboot mode
As pointed out above, theres fastboot mode and flashmode which bypass the failing OS bootup
I will return this brick to the shop, thank you for the proposals!

You obviously have no clue what a brick is. You have a bootlooping device which is nowhere near a brick. But that's probably a detail you're not interested in.
Try to follow the steps above to repair (=basically a full on, clean reflash in Sony vocabulary) your phone and get rid of the bootloop.

Hi guys.
first ever post in here!(because nearly all of the time i've found an answer here!! cheers!)
i've had exactly the same problem and been looking all over for a solution as i also have the boot loop problem occurring. tried the repair options in pc companion and also SUS. if i'm right the battery has to be above 50% to update and i'm pretty sure it's drained. i remember when flashing my htc one x when that was stuck in bootloop with low battery that to get enough battery I made a battery loop batch file which charged the device. however this was in fastboot mode and i don't think i have that option on my Xperia T. is there any way to charge the battery so as to attempt another repair?
Thanks in advance!

Just leave it plugged in. But i have used pccompanion when the battery has been as low as 10%.
I think you could try a hard reset. (Volume up and power button for 5-8 seconds, and then keep it pressed for a further20 seconds, untill it vibrates several times) Then try flashing a stock .303 file from the all in one thread via flashtool

leaving it plugged in just continues bootloop. sorry should have mentioned i've tried hard reset. i did try flashtool (0.9.9.0 version?) but it was not picking up the device.

why are you flashing an x10 relock bootloader ftf?
Choose an xperia T stock generic ftf from the all in one thread and place that in the firmware folder of flashtools and choose that when you hit the flash button

tried the flashtool with the relevant ftf file but after an initial connection phase it kept bootlooping back out of 'connected mode'. however i left i (trial and error) and it did start to flash the ftf but initially it stopped around 40% then re-bootlooped. i messed around with vol- connection to usb and power plus vol+ shutdown method (which incidentally did not vibrate) serval times left it plugged in and each time it started but stopped flashing around 92-94% complete. having got frustrated i just thought what the hell and left it to attempt to charge overnight (i say attempt as this method never seemed to charge the device once i had this problem). Anyways i must've done something right (or not!:silly as i tried it again but today there must've been some charge applied as it flashed on the second attempt i tried (the first resulted in another aborted flash) it flashed my T no problem!:good:
thank you guys!:laugh:

Glad it worked out for you.

But you activated USB-Debugging before your phone started looping right?

Press the power button and volume up for 10 -15 seconds.
it will vibrate once, that is like a restart
If you continue to hold for another 10 seconds it will vibrate 3 times. That is like pulling the battery.
Try turning it on after that

Have you flashed anything to the phone?
Have you rooted it?
Have you unlocked the bootloader?
If you dont know what these mean then you will not have done them.
Please plug the phone into the wall charger and leave it for a few hours then try the power and volume up button again. It is essential you leave the phone alone in this time.
Last question, when you press the power button and the phone is on charge does the red LED come on?

OK, try what I suggested. There may be other things that can be tried but if my phone behaved like that straight out of the box when I had not tampered with it I would take it back to the shop and demand a new one. Even we were to "fix" it via doing something on this site I would always be slightly worried I had a defective device.
Is it possible for you to return it?

What kind of shop is that? What country are you from? Thats terrible customer services!
Oh well, dont worry.
Have you installed PCCompanion on your PC? If not google it, download and install it. Also, look in the first thread in the development section for a thread called flashtool. Follow the links in that and download and install flashtool. We will need them if we are to save your phone. Also, they are good to have for pimping your phone later...

Last thing to try tonight
Download flashtool
Goto the installation folder and then into the driver folder.
Run flashtool drivers
Choose nx for ICS
tx driver
flashmode driver
fastboot driver
Then try again with pccomapnion.
If that does not work, download a stock FTF file from post 3 in the first thread of the Q&A section.Choose any file for the xperia t.
Open flashtool
Once downloaded, drag and drop the ftf file into the open window of flashtool.
When prompted attach the phone in flashmode (press volume down when attaching the usb cable)
Thats me for thenight now.
Let me know how it goes, but I wont be back untill the morning

[ STRIKE]Just to add one thing, before you try connecting it in flash mode, do power plus volume up till you get 3 vibrates. That way you know for sure your phone is off. If your phone isn't off it won't enter flashmode[/STRIKE]
Never mind, as Greg said I just didn't read good enough.

[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

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!

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).

Thanks for response. Finally flashtool 0.9.10.1b works for me!

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...

Is my Z1 bricked?

I was on the .270 FW but lost root and the bootloader got locked as upgraded using PC companion. So i downloaded an older fw 534 and downgraded my phone. Then rooted by phone. Till this point the phone was fine. Later i installed the latest dual recovery and unlocked the bootloader using the adb method and then. I had created a 270 pre rooted rom using the prf creater which had the latest dual recovery flashfile and supersu and flashed it using the dual recovery. Then i tried to wipe the device but it kept saying that unable to mount system. Then i rebooted but my device never started.
No led, no screen light, no vibration when using all keycombo. let the phone charging for 12 hours. Now i see red led blinking - for 3 sec the red led will be on and for 2 sec it goes off. Is it kaput or is there a way to revive the phone?

You will have to try and downgrade to the 108 firmware located here: -http://forum.xda-developers.com/showthread.php?t=2469191
You cannot upgrade to 270 from android 4.2.2 which is your 534 firmware this is probably why your phone will not turn on.
Get firmware 108 for your device
Using FlashTool to flash 108 to handset
Then root and install Recovery
The install pre-rooted 270

When using Flash Tool, when you have loaded the 108 firmware it when it asks you to plug your phone in, while your phone is turned off, press and hold the volume down button, and connect your phone to the USB cable which is plugged into your PC.

When I get to step 6 nothing happens. it's like I can't get into Flashmode. It just repeats connect your device. No matter how many times I do it or how long I hold the button. It's not recognizing the device. PC companion doesnt recognize it either.

Yes. I broke the charger connector thing in the phone. I had it repaired and it was working. I honestly think the place that repaired it messed with the phone to get more money out of me.
They fixed it and when I took it, once it ran out of battery it started to do the same thing again. I cant figure out what it is.

it seems that they didnt fix your phone at all. I suggest you go to a more reliable store or even if there is one near you to a sony repair store

VOL UP (Blue LED) is fastboot. This is working . Thats a good thing.
1. Turn the Handy off
2. Press and hold VOL+UP
3. Connect the cable
4. Wait till the LED is blue and take your fingers from the phone
The display will indicates nothing in this mode.. It's normal.
Now you can Download TWRP Recovery for C6603.
Have you got an open bootloader.
which rom you wanted to install? stock? custom?
1. Download the boot-twrp-v2.img from (please take the right version for your phone):
http://forum.xda-developers.com/xpe...t/recovery-stable-twrp-2-4-3-0-touch-t2182112​2. Make your PC available for adb+fastboot:
http://www.android.gs/install-android-sdk-adb-windows/
&
http://www.chip.de/downloads/Minimal-ADB-and-Fastboot_62500183.html​3. Go in folder with "fastboot.exe"
4. Press "Shift+Mouse-Right-Click"
5. "open command windows here"
6. C:\Flashtool\adb>fastboot.exe flash boot boot-twrp-v2.img
Go in Recovery and wipe/factory reset (or flash a new rom, ...)
Should work. Good Luck.

your solution is not going to help because its a hardware problem and pc companion wont help since the phone wont even boot up

in a similar (or worse) problem :
was just using the phone when it hangs .. Instead being smart and patient, I tried to hard-reset it .. the screen goes dark, my android wear disconnect .. but then I literally got nothing ..
tried to put it to the cradle, connect the USB to computer, no lights, nothing
fastboot mode : volume up + connect USB, no lights, nothing
hold power button : no lights, nothing ..
the phone feels cold, so the procs seems to be sleeping ...
any ideas ?

believe me hard reset didnt do that. Either your battery died and now you need a new battery or you phone died and now you need a new phone
