Do you have developer options enabled / can you do adb logcat while it's starting up and see if it outputs anything?

try power off then turn on by pressing random hardware button to boot in safe mode & if u lucky enough, can solve it.
else there is no other way. reflash data partition using flashtools.

You could try downloading the FTF and then flashing via Flashtool without wiping data. Might or might not solve the problem.
What were you doing before the bootloop happened?

since OP is unrooted, i doubt the prob is caused by other than data partition. no harm trying anyway.

i've got the same problems bros

X8 big problem, HELP pls

Okay, so it's like this:
It looks like I've got something very screwed up....
I was trying to crack PowerAMP, and in process it was written that I have to delete this file: data/data/com.maxmpz.audioplayer databases/folders.db. And so I did, I deleted it. And than I tryed to reboot my phone, and that the moment was when it got f#cked up.
I can't do anything, all the time I have errors like "The application app name has stoped working", and when I press force close(have nothing else to press), the new error same like that one comes up, and so all the time. And it finally reboots, it reboots from FLOYO logo, and then again I have those errors, and so all the time.....
I have tryed to access xrecovery but I can't. As much as I remamber, I can access it by pressing back while SE logo - yeah, that's what I'm doing, but nothing....
PC Companion repair my work but I'm kind of afraid cuz the phone is rebooting all the time.
Please help, I rly don't know what to do.....

my brother updated his xperia tx to jelly bean using flash tool before 3 hours... nothing showed in flashtool or the phone about any problem in flashing
in the last hour the phone started to restart & freeze

can a factory data reset help?? also we have a backup on PC companion so is it recommended to return it on the phone??
Try repair option in PCC.
Tapatalked from my TX

which one! I asked if you repaired or restored a backup.....
If you repair the phone it should be exactly like a factory shipped phone.
My only other thing to say will be have you got anything in your sd card (Both internal or external) that may be causing this? Any init.d scripts that reduce voltage etc...try deleting the contents of the sdcards and repairing again. (Obviously back anything up you want to keep)

i did repaired twice from PC companion and did once i think from the phone itself, and i don't have Scards its only the phone internal storge..
when i did it first in flash tool it didn't give me any error and then i did repaired it twice from pc companion however whats strange in ICS i never had the reboot problem
and if i remember correctly it only delete the programs etc, but the photos/music etc it never left the phone with both options i did...
so you suggesting to also wipe internal storage and repair to see if it reboot or not? i already have back up for all stuff so it won't hurt to try
thanks alot really for helping and sorry for my bad english ^^;
If you have a backup then try it.
Have you got a bootloop or do you have some reboots? What i mean is, does the phone actually boot up and only reboot occasionally or is it just bootlooping?

Wifi never connects

Hello, I hope someone can solve me the following problem:
I've been with Validus and RR CM ROMs and one day my wifi stopped connecting to any network, I thought reinstalling the ROM would work, but not ... Today I've been doing full wipes and was the same. So my last chance was putting a STOCK but has not worked, so I do not know what else to do ...
When I try to connect appears:
- Connecting ...
- Disabled
- Saved
But never connected.
Thanks to that I can help with anything ...
Regards

Try few of these.
have you tried connecting to different WiFi routers?
HAve you recently unlocked bootlader unofficially?
Yes, I have tried and the same, I unlocked months ago... Sometimes it connects (few minutes), I have tried to clean saved networks, wipe Google , recover WiFi from titanium backup... Now it is in authentication problem...

That's exactly what I thought and that's why I have asked you about your bootloader status. At times, you can lose your bluetooth and wifi while unlocking the bootloader which is more common if you unlock it unofficially. So if you can recall, when exactly the problem started. How long after you unlocked your bootloader ?
You say by reverting back to stock, it has not helped ? How did you revert back to STOCK. Try using Sony companion to repair your phone. That might help.
If that doesnot work, try relocking your bootloader on stock and see
Well, at times weirdest things seem to work!
I suggest flash STOCK which is device specific. i understand there is variation in Xperia Z models and thus I suggest you use the one which is device specific and report back,
By the way, is any Sony Care centre near your place ?

I don't think it is because of unlocking because was officially and I have being using and changing ROMs and there wasn't any problem.
Maybe it could be when I flashed cm-12.1 (RR ROM). Then, I flashed stock one with flash tool to fix my WiFi, is there any different with companion? I can't go to Sony I am travelling in few days, and I need a phone soon!!!

The only reason I'm referring you to Sony companion is that it might fix the issue as it is official way to do it.

I am afraid I do not own an Xperia Z . I actually answer questions that no one answers in different forums.

Please help: Phone freezes and reboots

I have a problem, hope someone can help me.
First time i haven't rooted my phone lol. Since update my phone randomly freezes and reboots, sometimes it just turns off, which means it doesn't shut down but screen turns black and its off. I wonder if someone else has the same problem and could solve it or if someone knows how i could track this error to get rid of it. Some sort of logging program i could use for example but as i said phone is not rooted. Appreciate any help. Thanks
try clearing the cache or if that doesn't help manually download the firmware (on a stable wifi connection) and flash it again.
when did you get the phone?
share the phone's model number and the software version running please

well a factory reset will clear your cache for you but if that not where the issue lays you'll still be in the same predicament.

Question Mi11 stuck on bootloop

Hello guys. Hope y'all are doing fine. I'M NOT ! I've got a problem with my Mi 11. So, at first, my phone was telling me that there was too many files on it and that there was no space anymore to add more things on it. Which is okay. Then, to resolve that problem, I tried to uninstall an app which made my phone go black and then got to that ''Recovery Menu''. I tried everything ! I triedd Rebooting, so I go on Reboot but then it goes back to Recovery Menu. I tried removing the SIM card, I tried to ''Connect with MI Assistant'' but the app won't recognize my phone. I tried to go on Fastboot with the Volume and On/Off button but it stays frozen on that image of the russian rabbit. I tried holding the volume buttons while the phone was restarting, doesn't work. I tried to "Safe Mode', but it doesn't work. The volume buttons are working well. I even tried cleaning my phone to see if some dirt got stuck in it. I tried tapping on my phone. I've tried to put it in the freezer. I tried to let it lose its battery and then plug it in, still didn't work. I don't wanna lose my data... There are extremely precious things in there that I cannot afford to lose... I'm begging for help, friends ! Please help me !
)I know there has been many topics like this one, but I've already tried everything I've read
I'd like to make Mi PC suite work so I can save everything... Or I'd just like to get my phone out of this recovery mode.
Thank you for reading guys. I wish you a nice day

You cannot perform a Backup as long as the phone is in bootloop, if the wipe works you can only recover the data saved previously.
