[Q] continuing restart after update

Hi,
i have a x8 with 2.1.1 A06 (ithink), cyanogen mod and rooted. I just updated to 2.1.1 C00 with sonys pc companion tool, which worked perfectly. But after the update the system always restarts at the ericsson logo.
I already tried the reset to defaults by using the left and right hardware button on startup but it doesnt work.
Anyone has an idea, what i can do to start my x8?
Remove battery, wait 2 minutes, insert it, leave phone turned off. Reflash stock rom using SEUS.
thank you
Thank you,
it worked.

[Q] HELP! Xperia Z wont boot past Sony screen after flash

I tried to flash the 4.2.2 update to my xperia because i didnt want to have to wait for my carrier to release it. I used flashtool but i flashed the wrong ftf file. now my device will not boot up past the Sony logo screen and it keeps restarting it and each time it only gets to the sony screen. I have tried to flash a different ftf file and the phone connects to flashtool but when it is going to start flashing the device switches on and thus is dissconnected from flashtool. it is the c6603 version and it is rooted but not bootloader unlocked. any suggestions?

If you hold power button alongside volume up until the device vibrates, it should turn the phone off. Now it won't reboot anymore, and you'll be able to boot in flashmode.

SUS says i have the latest software and the phone doesnt stay on long enough for PC companion
Have it sorted! I didn't do anything differently to be honest I was almost throwing in the towel but I tried using flashtool one last time and it worked. Thanks for all the help

This forum is for Xperia Z, not Z Ultra
Anyways, you'll need to give us some more information. Did you flash your divece? Is it rooted? Which software are you using etc.
If your bootloader is still locked you could try to repair your phone using Sony PC Companion.
If not please report back.

Xperia SP bootloop

Hi everyone,I restarted my Xperia SP because it didn't show the volume (I changed the design) bar and now it's stuck in a bootloop and it also gets very hot (sometimes you see the lockscrenn but it restarts again).
I tried connecting it to PCC but it isn't recognized. Pressing the OFF button on the back also doesn't work.
The bootloader is locked, there's no custom recovery and it's not rooted running stock Android 4.3.
I hope you can help me.

I just 2 week ago also failed to root and having this bootloop.
what i did is
you using the SUS to reformat and reinstall your stock rom
Or if your phone can be detect by Flashtool,
You may try use the flashtool to reflash the rom/stock.
Or if your phone still can go into CWM (If you got any)
also can try from CWM
For some reason the themes cause a bootloop (some of them at least) so be carefull when using one

I see sony sign and it boots again...
So I've tried flashing the rom again tried using the tool in PC Companion
Still no luck and bootloop continues.
Anyone know whats wrong and how to fix?

try reflashing stock rom using flashtool

Can't turn on my Z3+ After Sony Logo it has black screen after nothing! Please help!!

Hi all,
I already try everything to phone turning on, and working again!
Flashed it with flashtool, the result the same.
Tried flash twrp and another boot.img in fastboot mode, but this also unsucessfully.
PC Companion say no available software for it!
I don't know what can I do with it to working!
Flashtool flash is okay, flashtool said unplug and turn on, but when I turned on it just appear the Sony logo, after it has black screen!
What can I do yet with it to working?
Please help!!
Possibly the battery died?
Because I charged it 2 hours, after I use flashtool and fastboot mode to 20-30 mins, after I want to turn on the phone, but I get the picture from low battery.
Sorry for bad English!
Did you do a full wipe? When you flashed your fw on flashtool
Yes!
