Bootloop, no CWM, no Flashtool = Z Lost ?

Hello dear Community,
the prehistory ... about 2 weeks ago I get rid of my S2 and switched to the Xperia Z and I`am completely satisfied.
Because of my pre-"experience" with the S2, various Customrom's, Root and CMW I chose this day for these steps in the Xperia Z .
Got this in the course of the day and I Rooted the Phone and installed the latest CWM Recovery (bootloader locked). So far everything is working fine right after installation, I done a backup of my current StockFirmeware, if something goes wrong to have a backup ready.
After the Backup I Flashed this ROM
[ROM] [XZ] [07/03] Xperia KA02.2 Z Revolution ™ |
... via CWM, before the installation of course I wiped the Z, that nothing can go wrong ... I thought (backup?) ... The installation went smoothly, rebooted from the recovery and all i got was a .... Bootloop.
And here I am hanging tight since noon today.
Phone starts ... xperia logo appears, restart ... xperia logo appears, restart etc, etc. I thought I might still'm coming back into CWM, but None, no green LED on boot, if this is so, one should press on to the Volume + button to get into CWM ... doing nothing but looping again and again.
So i waited all day long until the battery was empty. After that i connected the Phone for hour to the charger. After an hour of loading time i tried to turn the phone back on ... But still no green LED .... Bootloop continue.
So i let the battery empty iself again. This time I connected the Phone via USB without switching on. Started the Sony Flashtool pressed the Volume- key and the Xperia connected to the Software, but due the Locked Bootloader i can´t to nothing.
That´s what i have been tried to bring this thing back to Life ...
Hope that anybody can help me get rid of this Silly situation
and BTW: SORRY FOR MY BAD ENGLISH !!!

You can try Sony Update Service.

Thank´s for your fast reply,
git my Problem solved
Wrong version of Flashtool was installed, so i downloadet the beta2 out of the Forum and now .... my Phone is back Alife

For those who have the same issue, try too re-flash the firmware following the procedure below :
1/ Follow the procedure for flashtool
Tick erase data if it still does not work
2/ Wait for flashtool to tell you to conned your Xperia Z
When it does get ready to connect it (step 3)
3/ Wait for you bootloop cycle end
--> Wait for the screen to turn black
--> Once it's black press and hold volume down
--> Connect your Xperia Z to PC
Step 3 must be done really quickly before the bootloop cycle restarts.
Hope this helps !
if it does press thanks button

Thank u
I did this procedure and it worked
My xperia z connected to pc in flashmode in step 3
And i flashed kernel and rom after that
Thank u very much

PHONE STUCK-white triangle with a screwdriver in it and a blue bar below (resolved)

hello all!
my phone was working properly (rooted but not boot unlocked)
pc companion told me there were a new version availlable (.253) I accepted, install, reboot, everything was fine.
I tried to backup my data in order to change the sd card to a bigger one...then it told me there was a problem while backuping so I did a reboot
this is where the problem begins:
now I have a white triangle with a screwdriver in it and a blue bar below it with an animation inside and it's stuck there...what does it mean for a start?
can you please help?
I'd like to recover it in order to get back my data (photos and video I wanted to put on the new sd card)
tried flashtool but it doesn't recognise the phone...
note: before doing all that, free space was low on my XZ internal storage (like 300 megs)

Unplug your phone from the USB cable and then start, see if that helps

This is exactly what I've encountered, can't find much help in the web, re-flash with wipe cache no joy, in the end re-flash with wipe data boot normally, last backup was 4 days old, restore and lost 4 days game progress...
Sent from my C6603 using XDA Premium HD app

That's strange.
Also had the same.
I updated to the .253 ROM and firmware etc and everything working fine.
I then rebooted after removing some system apps and got this.
I left it for a while and still stuck there.
Pressed a few buttons and still nothing then it suddenly rebooted (not sure if related to pressing the buttons or not) and everything was fine.
Then when it booted up it did the NFC firmware update so maybe related to that.
Not had it since and rebooted a few times.

thanks for replying guys.
problem really is that I can't use flashtool, for some reason I can't go in flashboot mode (green led right?)
and in fact I don't know all the key pressing procedures (if someone can post them all)
...but I think I got the press down and connect right, problem is that I have the green led for less than one second and then nothing...

Hi,
I also encountered this when I tried to use the old root method of .253. (yah, stupid of me but managed to salvage)
Just let it run for like 20 minutes or so and it will reboot subsequently. (As long as the progress bar still move, you should be ok)
Seems like a self-recovery process in place I guess.

yeah I guess you're right , but the first time was so long (more than 20 minutes ) so I thought it was dead...it is obviously some kind of self repair,
because now after a lot of reboots it suddenly started correctly after 5minutes of this blue bar moving....and now working? WTF?
things that I did in case it could help:
-used flashtool beta 4
-flashed a base .434 in blind mode (choosed xperia Z in the list)
-went into flashboot (press down and then plug usb) I had the green light for just a second...(I also installed EMMA drivers from sony , don't know if it helped)
-reboot then wait (I put it also on the docking bay , don't know if it helped as well but it made the blue bar go faster it seems, not sure tho...)
I used "hard boot" also : just jkeep pressing up and the power button until it vibrates 3 times.
maybe just puting it on the dock and then wait (quite some time) is enough (and makes sense)

I just had the same issue - WTF!!!
I just let it sit there for a while and it automatically started.

This is f*** crazy smart (stupid) phone.
DOn't know exactly what my wife did, but I doubt she flashed anything:laugh:
The battery died, she conncted to the charger, most probably with pushing some of the volume buttons and phone booted into Triange mode. Now it's stuk in this mode since an our.
I did Hard reset, but after phone is plug into wall charger it automatically boots in Triange mode.
This is in stock ROM without any modifications, unlocking, anything.

Just wait - sometimes it takes a while but it'll eventually boot up.

I think [NUT] said somewhere that this is a repair of certain permissions by the phone itself. I've only ever had this for some minutes - but it is possible if the battery an out it could invoke this. Shouldn't be anything to worry about.
And I think fastboot is blue led - you could try flashmode.

I tend to do lots and lots of flashing and mods so I've seen it several times. The first time caught me by surprise and lasted for a long time...now I'm just used to it ..

In my case waiting in triangle mode did not helped. Was waiting 5 hours at work. I flashed with flashtool again stock ROM without wiping data and still no response.
FInally flashed with wipe and phone is running but all data gone. What a crap.

Boot Loop - How to turn off the phone?

I tried to unlock bootloader and got a boot loop.
Then i flashed the 343 FTF but it continue and now i dont have recovery to shut down the phone.
I think the battery will go 0% soon.
how can i at least shut the phone down? pls..
Sry to create a Thread but i dont have much time to search more :/
EDIT:
I finally got the phone to start, so i'll tell the "history" here to people that get the same problem as me, and ask some question before do anything wrong again.
History:
1- I was on .343, rooted, bootloader locked. Decided to install the 1.253 rooted version with dual recovery. Everything was fine, working great.
2- Then i passed to unlock the bootloader. Followed that thread... everything seemed normal again... disconnected the phone and powered it up.
3- The boot loop started. Got the sony logo, the lights flowing, and restarted... again, again, again
4- I entered TWRP tried to do a factory reset, got a error message... can remember what, but something about mounting...
5- Shut down the phone using TWRP. Opened flashtool and flashed the .343 TFT, Everything ok again, unpluged the phone and started it. (Didnt choose to wipe data and cache).
6- The phone boot loop again. That time without recovery. I got desperate and posted that topic.
7- Finally got the phone to shut down.(thanks boyob32). power button+volume up until it vibrates 3 times.
Basically is that.
SOLUTION:
Searching more calmly i found that thread. Used the Flahstool again (that time wipping data and cache).
The phone finally started up!
Now some question to not make myself a fool again.
1- What could i made wrong?
2- I'm a little scared to try to unlock bootloader again... Since i got no error when doing it first time, is it already unlocked?
3- when i was using flashtool with the phone in bootloop got some errors messagens regarding drives. Before that everything was OK. Should i install them all over again?
4- Can i unlock the bootloader before update to .253?
thanks again. you guys are great!
PS: I can't edit the topic title, sry for that.

Hold the power button and volume up together, after a while it will switch off.

XZ in continious bootloop, no matter what i flash/do

Hi guys,
Device info:
Model C6603, Unlocked bootloader
So i have the following problem, my device is in a bootloop and i can't figure out what the exact issue is. I'm out of options at least.
First a little background on how it came to be: (scroll down for short overview)
Before official lolipop came out I've been on CM12.1 for a few months, cm-12-20141221-INFECTED-yuga to be exact. When official lolipop came out I installed C6603_10.6.A.0.454_Customized_HK-Rooted+Xposed Modules for LB following the instructions, although i see the thread has been modified (name, updated etc.) the instructions are the same. I did not install Xposed yet, because i wanted to try stock+root first.
After a few weeks of normal use, i used google maps navigation. This worked fine but when i arrived at my destination and picked up my phone closed google maps app but then my phone crashed. It rebooted to the point where i had to enter my pincode, but every time i was entering my pin it crashed and after a few tries it dind't even got to the lock screen but only showed the sony logo and rebooted(bootloop). I noticed my device was getting hot and left it alone for a few minutes, after that i started my phone again and was able to use my phone again. Until I started google maps again for the way back and enabled gps it crashed again, the same thing happened the phone would reboot when entering my pin, the phone wasn't hot this time. I left the phone alone till i got home, put it on the charger and the next day my phone worked fine again.
A few days later i was outside in the sun whatsapping, when the same happened my phone crashed and rebooted when entering the pin or slightly after. The phone was feeling hot, also because it was exposed to the sun for a while, in TWRP recovery it showed temperatures around 70 degrees celsius (i don't know if this is too hot?). After i had left the device alone for a while and try to boot it up it got stuck in a bootloop (sony logo), after a night of charging it got to the point of entering the pin code again but crashed and got stuck in a bootloop again (sony logo). And since then i'm not able to get rid of this bootloop. However i could still get into recovery (TWRP).
First i tried to reinstall the rom, factory reset and flash via recovery: C6603_10.6.A.0.454_Customized_HK-Rooted+Xposed Modules for LB
This worked, and the device booted up but after a while it crashed and got stuck in a bootloop again (sony logo).
So all summed up:
cm-12-20141221-INFECTED-yuga
>> C6603_10.6.A.0.454_Customized_HK-Rooted+Xposed Modules for LB
>> Google maps navigation >> overheated >> bootloop (sony logo) >> charging night >> working >> whatsapping in bright sun >> overheating >> continuous bootloop (sony logo)
What i have tried:
- Tried booting without sim card, withoud sd but doesn't work
- Flash same rom via recovery C6603_10.6.A.0.454_Customized_HK-Rooted+Xposed Modules for LB : Worked once, but then crashed and went back in bootloop, now when i flash this only Bootloop (sony logo)
- Flash updated version of http://forum.xda-developers.com/xperia-z/help/lollipop-5-0-2-10-6-0-454-pre-rooted-t3116205 via recovery : Bootloop (sony logo)
- Flash kernel via fastboot http://forum.xda-developers.com/xperia-z/development/kernel-unlocked-bootloaders-t3114234 : Only recovery works
- Flash stock kernel via fastboot: boot (sony logo) one time then turns off
- Flash stock lolipop (with and without bootloader unlocked) via latest Flashtool : Bootloop (sony logo)
- Flash stock lolipop via xperifirm (C6603_10.6.A.0.454_KPN Mobile NL) xperia (with and without bootloader unlocked) via latest Flashtool : Bootloop (sony logo)
- Flash stock kitkat (with and without bootloader unlocked) via Flashtool: Bootloop (sony logo)
- Relock bootloader and Sony PC companion restore latest firmware : Bootloop (sony logo)
- Restoring serveral backups from TRWP and Phillz touch but they all result in the same bootloop, while at the time the backups were made there were no problems.
I'm pretty much out of options and begin to thinking something was damaged when the device overheated or a bad partion of a kernel is still stuck in the devices kernel.
Does anyone had the same issue, if so how to fix it? Or another option i could try, maybe someone spotted anything i did wrong?
Current state:
Locked bootloader, stock lolipop 10.6.A.0.454 flashed via Sony PC Companion recovery
Boots into setup, after a few reboots I completed the setup. But still randomly reboots when trying to use some apps or in general leaving it in standby for a while (might be due instability).
Thanks in advantage,
Jonathan

So the only things that you do that do not result in a bootloop are flashing a kernel. Try flashing a Stock kernel with Flashtool --> open flashtool >choose the flash button at the top left > flashmode > choose the firmware > check cache and data above and below check Only Kernel. Post result here...
Good luck

Don't do this. It will wipe your data and flash everything but the kernel, therefore losing root etc.
If you want to flash a stock kernel, you must leave everything in the "Wipe" section unchecked, and check everything but "Kernel" in the "Exclude" section.
I don't think this will help anyway, being that you're already on a stock firmware flashed via Flashtool.

Thanks for your fast reply, I think you meant: check everything but leave kernel unchecked (as kingvortex replied at the time of writing)? Since it is an 'Exclude' list. I flashed stock kernel, it shows the Sony logo and then shuts down. I used stock lolipop kernel from 'C6603_10.6.A.0.454_KPN' Mobile NL, and i also tried 'C6603_10.6.A.0.454_Customized CE1'. both have the same result.
I've got the most "life" after i restored my phone with pc companion to 10.6.A.0.454. Then, after being charged via the wall charger for a while, it boots up normally and goes into setup, since it is a complete restore. But crashed around the setup screen for wifi. The other options i tried do not come any further than showing the Sony logo, this stock one shows Sony logo >> android logo >> boot animation + sound.

I'm thinking it might be a case of a dead battery or battery controller of some sort. Because the phone only boots up normally, with stock android .454, when the phone is connected to the wall charger. Whenever i pull out the cable the phone crashes and reboots, also when not connected to the charger it gets stuck in a bootloop. However when the phone is connected to a charger and working for a while it still randomly crashes when using the device, sometimes these moments are suspicious because it sometimes reboots when enabling gps, wifi, mobile data or when starting an app, phone call or synchronizing accounts for instance. On a side note sometimes the battery percentage drops about 6-9 percent when rebooted one time or when crashed, also when i connect my phone to the charger the status led is red but when done showing the sony logo and when charging it turns green (or yellow, depends on battery percentage). This is why i think something internal is not working properly whether it is the battery or the battery controller, i don't know.
I still find it weird that the phone was in perfect condition before flashing .454 stock lolipop, it might be due to overheating that some components where damaged. At least i'm guessing this is the case because i know no other reason why it would show such behavior. Is there someone who has experienced something like this or another solution i might try?

In the mean time i bought a Z3, my XZ is definitely dead now after the battery has discharged and i can't charge it because it's constantly rebooting. However flashmode and fastboot are still working. Thanks for the replies. I might repair my XZ if i can get my hands on a cheap (broken) second hand and replace the internals, but i'll see.

Hi, i have the same problem... i cant charge and the constantly rebooting... and in my case also... when i try to flash any ROM, flashtool and Fastboot are stuck for 1 hour when try to flash system.sin (system.img)
i stop flashing after 1 hour... not sure if could finish after 2 hours :/
Cant use PC Companion because dont have charge in the phone (locked bootloader)
Any suggestion?

need help, regarding xperia T lt30p cant turn on

hello everyone!
i have a few questions. and i have done my research yet i still find no solutions so i will ask here
this is my story...
-root,unlock bootloader,flash cm12 android 5.0.1, ran cm recovery
-running fine for around 2 weeks.
-in those 2 weeks there has been times where phone drained to 0 its battery, then charged it then it was fine
-suddenly one day. charged it after it drained completely. then wont turn on.would boot up to 'sony' screen then repeatedly reboot and do the same thing again.
-could enter recovery, but when trying to reflash rom, phone would reenter boot loop
-have tried charging for days.
-have tried removing battery, same thing
-then used flashtool, relocked bootloader, reflashed stock firware, now cant get into recovery, flash successful, yet phone still cant turn on pass sony screen.
is it a battery problem?

just to add, ever since the first time it started having this problem, i could never get the phone to turn on at all without plugging it in .

Hi Jetdin
had the same problem with my XT a year ago, when a powerbank somehow "nuked" the battery-logic... After that, I had the pleasure to know what a deep-discharge feels like :-/
To revive my XT, I had to replace the Firmware... I did it this way, maybe you can try a "factory reset", maybe it already works out for you...
1. loading it (turned off) 24h with original recharger (don't try to turn it on)
(1a - if you can reboot it to save apps, data, files - do it)
2. reboot into TWRP - and do a factory reset
...and try your XT; with luck, this already solved your problem... if not:
3. get the new image of your choice - i downloaded whiteneos 12.1 - works like a charm... and copy it to an sd-card
4. after (re)loading the XT - boot into TWRP - and install the new image...
...reboot and hope this solved the problem...
Good luck!!
Edit:
that it only stops at the sony-logo sounds like "operating system not working" - maybe a "higher" OS-version will do the trick?

Thanks for the reply theunlucky.
I have tried most of those.
The cm12 was on Android 5.0.1
The stock firmware for the Xperia T only goes up to JB huhu

unlock your bootloader again
1. download whiteneos cm
2. extract the boot.img and flash it via fastbootmode
3. reboot
4. if you see a led hit vol + ( or vol - ) several times until the led color changes
5. now you should be in recovery... try to flash cm12.1 from whiteneo and reboot
