[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.

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...

XPERIA Z red led blinking

hi all,
i have an xperia z c6603 lcoked,
i successfuly installed cwm on it, after that i tried to install a custon rom on it,
i enter recovery, wipped data/cache and installed from zip the zip
it wrote installed successfuly, without poping up the aroma installer (maybe this is my first problem, maybe i broked the stock rom )
but now when i'm trying to turn on / enter recovery nothing happend, only a blinking red led even when i puted it on charge
how can i fix this problem

Hold volume up + power for 10 seconds, then release them. Now, hold volume up and plug it into a PC via USB. You could probably use Flashtool now to flash a FTF file of your region. That should fix it.

thanks for your answer,
i have the blue led but usb not detected as debugging mod, will this work ?
should i worry about the led blinking ? i was on flashing roms on my old S3 , sony is more complicated ...
thanks dude

Thank you very much "Zorua", after trying to flash a Rom, I stayed stocked with the red led, without being abble to boot or access CWR, and you suggestions worked!

[sos] xperia z not booting

Hey guys! My Z has been awesome these past few months and w the recent 4.2.2 update, its been PERFECT. I finally rooted it last week and installed CWM for locked BLs. However I haven't been able to boot to recovery so I downloaded an app called Quick Boot (Reboot ). The thing is, when I selected "boot to recovery", my screen went black and now I can't start my phone!
The LED also does not light when plugged in, and I've tried every possible button combination with no results.
Please help! Thanks!

Try holding power and volume up. You should feel a vibration and the phone should restart.

You could try flashing a stock rom with no wipe with flashtool.

Your phone doesn't need to be booted to use flashtool. Just give it a try. If it doesn't work, you could try doing a repair with SUS - http://www.sonymobile.com/in/tools/update-service/
As for that app, I doubt it has bricked your phone. Any app that has a 'reboot to recovery' option will not work on our device as we do not have a recovery partition. There is a fix for this in the original development section that allows 'reboot to recovery' to function properly.

This is very strange. When you held power and volume up, how long did you wait? You have to hold them for around 15 seconds IIRC.

What the hell, I'll try help. If you're in windows 8 you need to install the fastboot drivers booting without driver signing, what os are you on? if you need more help reply or check my profile for my skype user.

Try to push pwr + vol down to enter into flasboot.
You should also try pwr + vol up until the phone vibrates 3 times. That's a hard reboot.

fastboot is vol up + usb while device powered off. FLASH mode is vol down. What exactly do you get from the device? Any feedback at all? Backlight? Vibration?

Make sure your Xperia SP is Switched off. If pushing back button doesn't help then keep the back yellow button pressed for sometime and along with that keep pressing volume down button and you will boot into CWM Recovery
After that either reboot or shut down the phone and just simply reflash it.
Hope I helped

The yellow button part has already been mentioned...
Furthermore, who says he/her has recovery installed? He/her didn't so your suggestion is rather worthless at this time.
I notice you're trying to help allot of people lately, but try doing so by giving correct instructions rather than telling people what you would do to your own phone in similar situations.
First question should be if he/her has installed any custom ROM or kernel.
If he/her unlocked her bootloader or not and if a recovery is already installed.
The answer to the above questions will decide on how to approach this problem.

If you see properly you can see that he has already been advised to flash 4.1 stock kernel THAT MEANS HE HAS UNLOCKED BOOTLOADER, and if someone has unlocked Bootloader he would definitely have roott access and recovery installed (common assumption)

He has been advised to flash a kernel, but did he do it? You can't know for sure, Mr. CAPITAL!
