[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 won't turn on!

So my phone will not longer boot. It started like this: all of a sudden it wouldn't work properly when in a phone call, I could hear the other person but they wouldn't hear me. So I just turned off my phone and when I tried to turn it back on the triangle icon wth wrench and screwdriver appeared as seen in the image below (I had around 40% battery). I left it like that for almost an hour and since it wouldn't turn back on I did the power+volume up but it would load back on to the triangle. Then I removed the micro sd and power+volume up and it loaded the sony logo, then the xperia logo, then this sony colored waves/smoke started and the 3rd time this "wave" crossed the screen, it just froze and began a never ending loop of sony+xperia+waves+restart... over and over again :S It stopped only after long pressing power button + volume up. I tried pluggin it on my pc and starting the Sony PC companion but doesnt recognizes the phone. I read in another post that they fixed this issue by connecting the phone to the PC and launching sony's pc updater. But I don't know what's this "sony pc updater" thing, if they mean PC companion Ive tried it out and doesnt work for me.
Thx in advance for any help! (btw, my xperia z is with the latest update installed)

Possible Solution :
Install the STOCK ftf file of Xperia Z into Your Phone Using Flashmode.
What You will need is
1. Flashtool
2. Ftf file for Xperia Z (Download the ftf from your device thread)
Flash The ROM ftf file.
You should be running the phone by the time you finish.

I fixed it!!

As dwarkesh2492 said (thx a lot by the way), all I did was download a stock rom (I found the italian unbranded version here http://forum.xda-developers.com/showthread.php?t=2293794) and flashed it with flashtool beta 6 ( tutorial on how to do it here http://forum.xda-developers.com/showthread.php?t=2240614). At first it wouldn't start flashing but I tried several times plugging and unplugging my phone while holding volume down and it finally flashed It was the 1st time I ever flashed a ROM or anything so I'm sure anyone can do it.
I hope it helped.

What method exactly worked for you?
I'm having the same triangle screen, I interrupted it by pressing vol up + down + power, and after that it just showed the Sony logo. The battery died and when I try to charge it now, the only sign of life is the red LED and "SONY". I won't go into flashmode (yet) so flashtool is not an option. I'll try to charge it whole night (am in the Netherlands) and try flashtool again tomorrow.
Btw. I am on RomAUR which is nearly stock .253 and this means I have root too. Locked BL. The problem appeared after rebooting the phone because I suddenly didn't mount the external SD.
Any help appreciated, thanks!!

okay it appears to be constantly stuck in flash mode, flash tool is finding it and verifying it in flash mode without holding the vol button down..
also pcc does not let me repair my software, it tells me it has been updated
also phone keeps bootlooping from flash mode to sony screen making it bounce out of flashtool

You are lucky that it is a soft brick just hold the reset button for about 10 seconds.
The phone will vibrate 3 times do NOT release before 10 seconds have passed because you would only "take the battery out"
This will erase your Internal SD data and hard reset the phone.

Thanks for your reply mate, I somehow managed to fix it. I flashed firmware with flashtool. Even though it didn't finish, it hung on reading phone information. I unplugged my phone and it came on.
I can only assume that flashtool at this point had frozen, And there for had somehow flashed it. Either way it's working fine, so happy days

[Q] Bricked Xperia c6603 that can't shut down

So the thing is, I decided to buy this phone from another person a few days ago while it was still working but it had this one problem where the owner told me about how the phone can't be shutdown unless the battery runs out of power. Any time you shut it down, it simply reboots instead. I thought it was most likely a problem I could fix after flashing, so I decided to buy it.
Using Flashtool I was able to see that if timed pressing the buttons and plugging it into my computer right before the reboot started, I could boot into flashmode. This phone came in the 4.4 KK firmware and the 10.5.1.A.0.292 Generic NCB build, so I flashed an older kernel and rooted it using Towelroot before reflashing the 10.5.1.A.0.292 Generic NCB kernal. After rooting (and testing if root apps can shut it down which didn't work either), with a locked bootloader I installed the XZDualRecovery using the method here because I was finding it so hard to unlock the bootloader and Flashtool wouldn't do it either. It automatically booted into TWRP recovery menu but when I tried to flash a ROM (existenz Ultimate 3.5 to be precise), it simply made the screen go black for a second and took me back to the recovery menu. So figuring it was a bad download, I downloaded a smaller ROM but when I rebooted I accidentally went into PhilZ Touch menu instead. Deciding to do the usual wipe before flashing, here's where I messed up like an idiot. I saw an option along the lines of "Wipe CLEAN for flashing ROM" or something and trusted it so much despite it saying it's gonna wipe the system partition clean as well (I still don't know why I accepted even when warned of that).
So basically now I have a system that boots the SONY splashscreen and then goes black with the back light still on unless the battery runs out. I can't shut it down no matter how long I hold the power button and if I restart, it boots back to the same thing. I have no recovery menu now thanks to my genius idea of wiping the system, and the only thing I can enter is flashmode. So when I try to flash an FTF firmware (I tried every firmware I could get) back into the phone with Flashtool, it would simply say "preparing for flashing" for about a minute before it says "device disconnected" because the phone decides to exit flash mode and boot normally. I have a locked bootloader (with bootloader unlocking allowed), so I can't flash recovery menus. When I try booting by holding the VolumeUp key and plugging it in, it enters flash mode only with the red LED on and I still get the same results on Flashtool.
Was wondering if there were any ways around this that I might have missed before deciding to open the phone and change the hardware? And if it comes to that, what would I need to change (have always been a software guy when it comes to phones)? Any tips and advice would be appreciated.
TLDR: Have a bricked c6603 from wiping the system, that can't shutdown and keeps rebooting and refuses to be flashed.

If you have time before the phone reboots, hold Volume UP and the power key for 15 seconds. The phone will vibrate once at 10 seconds. Keep holding the keys until you feel 3 vibrations. This will hard power down the phone.

^I've tried this and it simply boots back up again.

Hmm. That should definitely shut the device down, not restart it.
Sounds like there could possibly be an issue with your power button. I've heard of issues with the power button after water damage. Have you checked the water ingress indicators under the flaps? If any are red, it points to earlier damage from water.

Seems like you're right, I just checked it and it indeed has a faded red color on it. Do you think if I take the phone apart it the power button could be fixed or should I swap something else inside this from another Xperia?

I experienced this problem
Pls hold down volume When u connect your phone to pc via flashtool,
It will connect in flash mode
After that , just flash 0.230 kernel via flash mode ( kernel not rom )
Then disconnect your phone
Turn it off ( hold power button and volume up till it vibrates 3 times )
Then before it turn on again , hold down the volume down and connect it to pc via usb and this time flash 0.283 Rom ( not kernel )
This worked for me

Hard bricked xperia z1 - please help

Hi Guys,
I really need your help unbrick my Xperia Z1 C902.
Here's what happened:
I tried to flash a custom rom that wasn't compatible VIA AROMA ( I had MiUi 7 custom rom ) and it is now dead. It won't boot. No sign of life. No Vibration when pressed vol up+Power . Hard reset ( via sim slot ) has no affect on the Phone. No recogniztion to USB on laptop ( tried other USB cables as well ).
I have left the phone be charged overnight assuming the flash took a toll on the battery ( it was about 30% when I flashed the phone )and in the morning there was a red LED. Assuming the battery had enougfh power I tried to turn it on, connect to Laptop, Fast boot mode, flash mode but with no luck.
Day2:
Left the phone connected to the stock charger for about 20 hours or so.
No LED lights. No vibrations. No sign of detection on the laptop.
Sony Companion will not detect my phone via fastmode as well.
This phone is out of warranty so I was hoping you can help save some bucks before I take it to the Sony centre.
I looked through XDA all day but nothing has helped me bring my phone back to life.
EDIT:
I have downloaded India Stcok ROM via Xperifirm and tried to flash it but the flashtool does not detect the phone. Fastboot and Flashmode both does not detect the phone. Strange thing is, when I plug the phone to laptop holding the Vol down button, a red LED blinks for few seconds but the fastboot does not work ( as my phone has bootloader unlocked )
ADB does not work - No devices connected.
If there is anyway I can flash or install TWRP recovery ( or any for that matter ), I have the old working MiUI rom in the external SD card.
I will owe you a beer or two and a dinner if you 're able to bring my phone back to life. Please I am desperate.

Hi.
You have flashing led that means there is some hope first press and hold hard reset button for 15-20 seconds under sim cover then realizes it. Now plug in charger and dont touch the phone before 4-5 hours. Let it charge even though red led comes on.
After that disconnect your phone and don't turn it on wait for 5 minutes.
Also do check if the flash tool drivers are properly installed (window 8 and newer needs you to disable driver signature enforcement) use flashtool version 0.9.19.0, dont know why but this version works best for me.
Flash *.108 firmware (available in xda) also do always check hash after downloading.
Now try to flash the firmware as normally we do and hope for the best. This method worked fine for me many times.
Good luck..! [emoji111]

The flashing Red LED is bringing back some really bad memories of my own Hard brick. Try what kathanpatel suggests first - holding the reset button down.
Are your symptoms identical to this?:

There is a link to a post with instructions on recovering from the hard brick. Good luck.

The red button in a sim slot won't have any effect unless your phone is connected to the charger (not computer). Connect the charger, press and hold the red button for about 10 seconds until there is vibration. Then immediately push and hold the power button for a few seconds.
