[Q] Won't turn on - Xperia Z Q&A, Help & Troubleshooting

Hi!
Yesterday i think i may have installed/flashed a kernel for 4.2.2 instead of 4.3 as my phone was running(if this makes any sense).
I am new to android and kernel, ROMs and rooting, so I don''t know exacly whawt I did...
Well, anyways... Now, if i charge my phone, it starts up to the Sony logo and shuts down, starts up to the Sony logo and shuts down, untill the battery is empty..
If I connect it to the pc, it connects, disconnects, connects disscontects and so on..
Any ideas of what I can do?
(sorry for bad english, but try to understand )

Try to connect your phone in fastboot mode.
Choose in flashtool fastboot
connect your phone while holding the volume up key
what happens?

Just flash proper kernel with proper fw via flashtool
Downgrade from 4.3 to 4.2.2
also will stuck in bootloop.
Flash 4.3 firmware exculed data partition, or flash 4.2.2 including data partition to start phone.

Soft - bricked my xperia T, need HELP (SOLVED)

Hi guys, this is my first time posting here in xda,
I have a problem with my xperia T, it boot loops (starts up by showing the manufacturer logo, then shuts down, then starts up again)
and i didnt unlock my bootloader, and i didnt install CWM, no backups either
I only rooted the phone for the sake of chainfire, and when i installed it, it asked me to restart the phone and from there on the problem started.
I tried fastboot mode, but after 3-4 secs, the blue light disappears and the phone starts boot looping again,
I need help from you guys,

How do i do that? Sorry, im a newbie..
I think the pc companion cannot restore my phone since it cant recognize it. It starts up, then it shuts down after 3-4 secs
Also i dont see a back up and restore menu on my pc companion,

I would think that it would be the battery? give it a 10 minute charge and see if it starts
you do not need to turn your phone on for pccomapnaion to work.
Run pccompanion and run the software update and choose repair.
Only connect the phone when it prompts you

Serious Xperia Z WiFi + Bluetooth problem!

Hi. My xperia z froze at a game's loading screen and was stuck until I hardreseted it by holding power + vol up. After that, the boot time became extremely long. When the phone finally started I were about to connect to my WiFi, but the WiFi won't turn on! It just says activating, and stays like that. The same thing with bluetooth! Everything else seems to work, but the boot time is still really slow. I've been thinking about flashing CM10.1, if I will need to do a clean restore to fix my wifi, should I flash CM10.1 instead for stock rom?

Do a internal wipe (factory reset) under settings/back up and restore follow by a repair through pcc or sus. If it doesn't work it could be your router.

Hi , sorry for reviving old thread, i have the same problem with my Z,
official firmware, bluetooh and wifi couldnt turn on.
been digging xda and other webs, to no avail.
Hope senior members here could help.
Did you try to reset your phone or to repair it via pcc?
done both, no help at all...
downgraded to 4.2 same issue, the wifi just wouldnt turn on...
bluetooth is the same
I too got this problem suddenly, did resetting the phone, flashed using flashtool & repaired using Sony PCC but to no avail.
Is it a hardware problem ?
Help me guys.

[Q] Xperia Z Refuses to go into flashmode

Before posting that I'm idiot and I should have searched for the solution myself I want to say that there was no actual solution to my problem!
A month ago I decided to install CyanogenMod 10.2 because of more camera options so I backed up my TA partition, then unlocked my bootloader and installed CyanogenMod 10.2 that was perfect for me, but as official 4.3 is going to be released I decided to migrate to stock android and ran into a problem, I downloaded many FTF's for my C6602, downloaded new flashtool also all drivers are perfectly installed but when it came to loading phone into flashmode it refused to do so, I'm holding Volume down button and connecting USB into the main USB port on the PC, first I see red LED then suddenly it changes to GREEN for about half a sec and then turns off, as for Fastboot mode it works perfect I even tried flashing different kernel but it did not help, I also tried and successfully installed Android 4.4 KitKat OmniRom without problems but I still can't get into the flashmode, also I was unable to use EMMA because I did not receive confirmation e-mail. Please help... Thanks in advance.
I managed to reflash to stock .67 firmware with new flashtool but the led was not green during the installation it was off but it still got flashed, now when I reflashed my phone, I rooted it and restored my TA partition , so now I want repair it with SEUS but the problem still exists phone wont go into flashmode !!!!
Once green led goes of and screen is black, you ARE in flashmode
Make sure flashtool prepares files BEFORE pressing volume down and plugging usb cord in.
There is no persistent led or visible screen in flashmode.

Yea you were correct for some reason when I started updating phone with SEUS it just restarted and started update, so it seems that it really was in flash mode, but what's wrong with the led? It was always on once in flashmode ...
Forget SUES. Just flash a stock FTF for your region. Sony won't know the difference. There's plenty out there. Which one do you want?
Edit; In flashmode, Led stays on until flashing starts then it turns off while system is being flashed.. In the case of PC companion or SUS, it will take considerably longer while files are downloaded, but with flashtool, the files are already in place, so it goes off almost instantaneously

Thanks again, no I just wanted to get BE back Thanks to guy who invented TA partition backup : )

That's a brilliant tool.
Just be sure to be on stock, rooted, with USB debugging on, and superuser accepting adb shell command while restoring:thumbup:

Just wanted to say I was a bit worried my xz was not in flashmode the first time I flashed un-branded firmware as the led did not stay lit..
When I used to flash my old Arc S the light would remain on until flashing finished...
Thanx for confirming this !!
Different Problem with Flashmode
Can someone please help me, When I unlocked my bootloader (Xperia Z) I didn't use flashtools. I used SE Bootloader Unlocking, this software worked well for my Tipo and S. What happened is that my bootloader got unlocked but my flashmode got corrupted. Fastboot works fine. But when I try to get into Flashmode, the green LED blinks for like a second and nothing happens. Does anyone know how I can fix this? Please Please help me? I can't update my Baseband to go to 4.3.
I wouldn't mind relocking my bootloader to go back to stock, but I need flashmode to this as well!
That's how it works on The Z. Nothing to worry about
Just let flashtool prepare the files , then plug in to pc holding volume down

[Q][C6602] Kind of a bootloop

Good evening everyone,
I'm having an issue with my C6602 lately, I updated it to latest firmware through OTA, a day later, it just wouldn't boot up and got really hot.
I tried flashing another firmware with flashtools, succeded, but then, whenever I turn it on, I have 5 seconds max, and it reboots (unless I turn the screen off, this way it'll work, but will eventually reboot if I turn on the screen.)
I looked in the forums, and tried most of the solutions, I even reset it using sony companion.
Now I'm stuck with kind of a brick, the phone doesn't turn on, but if I plug it to a wall, it boots up, but gets stuck on lock screen (irresponsive), reboots after a while, gets stuck, reboots, then gets stuck for as long as I keep it plugged in, then turns off as soon as I unplug it and starts bootlooping until battery dies.
Anybody got any idea ? Please do ask if you need any more details.
Thanks in advance.
Before you updated you was also on stock ROM?
So flashtool recognize your phone without problems?

Yes, phone is recognized by flashtool, now the issue is as follow (edited the first post too).

Try to repair with Sony Update Service(SUS).

If I remember well, the phone must reach 50% battery to be repaired with SUS, but this just wouldn't happen, when the phone gets stuck on lock screen, it gets really hot, and even if I let it sit there for an hour, the battery percentage won't change much. I'll try it again anyway, there is no other method than SUS ?
Edit: It says I have the latest version installed

Since you get your phone recognized by SUS make sure battery is more than 50% charged and try the repair option.
SUS and flashtool is your friend i guess..

Repair option, hum, I just tried the update thing.
I'll try to leave it plugged for night (and hope it won't blow up), and then try to repair tomorrow.
I'll let you know either way.
Thanks

And if it stucks on lock screen, does it turn off if you hold power and volume up(12 seconds i thought you have to hold the combination, it have to vibrate 3 times)?

Yes it does, then it reboots, then gets stuck again (Sometimes it even gets stuck while there's the wave animation after the xperia logo).

just download an ftf and flash it via flashtool
open flashtool and connect your phone via usb cable while pressing the volume down button to enter flashmode

As I mentioned before, flashing an ftf didn't fix the bootloops, nor the freezing

If you flashed correctly with flashtool and SUS doesn't help also, I would say there is a hardware problem. Because more or less you can solve every software problem with your phone with a clear flash.
You don't have a recovery, right?

No recovery, no.
Im unrooted, and bootloader is locked, guess I'll have to take it back from where I bought it for a fix, it looks like a hardware problem (leaving the phone plugged for the night didn't change a thing)
Your battery has a problem, anyone would say. Try a fresh FTF install with wiping data. Also try repair. For that you need to charge your phone when it is turned off. And make sure FTF version is newer or at least same with your latest firmware worked fine.
