Try What?

Try using your phone without SD card and sim card. Msybe these cause the reboots

Hmm coincidence it is that I have the same name.
Back ot:
Try removing 1 or both and see if the reboots are still happening. I had the same issue with mine and it is a factory stock phone. No provider brand and non rooted.
And magically after the 4.3 update it began with sudden reboots(with the message sim/USIM removed). Within a matter of days 2 or 3 they became that frequent that I removed my sim and that's also when the reboots stopped.
Called the provider and told them my sim caused the phone to reboot somehow after it got updated. They sent me a new one @ no costs.
Put the new one in and till today no reboots. Think that is about 1 or 2 weeks ago.

Just tried with only sim, then only sdcard, and without both of them. Still reboots. I REALLY DONT KNOW WHAT TO DOOOO!!

Have you treid diffrent FTF files? 4.1.2 (.145) for example? Or 4.3 (.199 or .205).

I tried all 4.3 firmware versions, still reboots itself... 4.1.2 not yet will try tomorrow..

If you've tried different firmwares, and android versions. With/without sim/SDcards. You may have some faulty hardware.
Is your bootloader unlocked, have you tried any AOSP derived ROMs?

So how can i solve if it is so? I didnt tried 4.1.2 and checked the problem. The bootloader is locked, and never tried any AOSP roms.

Try a 4.1.2 firmware for a few days, if the problems persist then it must be hardware related so you'd need to send it for repair.

remove sim and then have a try.I just had the same problem three weeks ago.

Weird.
So let me get this right:
Android 4.3:
reboots with stock
reboots with stock + no sim
reboots with stock + no sdcard
reboots with stock + no sdcard + no no sim

Android 4.1:
It turns off randomly
When charging it doesn't do either

Also your bootloader is locked, correct?
And all these tests have been done on 100% stock? Root? Xposed? Any mods?
Did you try what @Darkierage said a few posts up?

Yea. Always been locked bootloader. Tried this with testing this without root (i think), because this rebootings happened when i had root, then i flash 4.3 stock thinking that flashing another fw will delete root also, am i right? Before this rebooting problems i had tried some xposed modes and made some soft reboots, dont know if it is that the problem.

If you read my previous post, i didnt know what he meant with that app?

That should be the first thing you do now. Flash it back to stock and check if it's working. If so, reflash CM again and you'll see what the problem is.

Have you tried:
1. repairing completely with PC Companion;
2. re-rooting?
you should do a
repair with SUS followed by a factory reset (internal wipe) under settings then try rooting it again.

[Q] Downgrade to .434?

Hi,
My first post here on XDA! I have a Generic NL .253 Rom (without root, BL locked) flashed on my Z. I want to downgrade it to version .434 so I can root my phone. The problem is, everytime I try to flash it with flashtool, whenever my phone boots up, I get a message saying it's upgrading NFC, then it suddenly reboots. This happens over and over (kind of like a bootloop). I have tried several .FTF files. Also, I don't want to do a clean flash, I have made several backups but I'm afraid they don't live up to my 'backup'-standards. Does anyone know a fix for this?
Thanks in advance!

Hey, thanks for you reply. Yes, I can. I reflashed my old .253 Generic NL software in between trying other .434 files and it still works fine.
The problem with the .434 is that my phone does boot, but it never properly boots, you know what I mean? It keeps on resetting, and displaying the 'NFC updating' message. Any ideas?

I'm actually having the exact same issue. I would like to downgrade so I can regain root. I have a feeling to fix the boot loop we would have to wipe the phone. I'm just deciding if I want to try that yet as it sucks redoing everything and the phone is running so good.

Yeah exactly, the backup options are fairly limited since I haven't rooted it yet, and I kinda feel there should be a way around this loop
without having to wipe all my data..
i suggest wipe. it should work when downgrading.. i hope it will work on you both as i downgrade my z after updating to .253 and i dont have any bootloop issues...

.434 can be rooted either bin4ry or doomlords method.. and .253 can achieve root using nuts method or wawyed..
So it's possible to root .253 without having rooted before? Did not know that, I will look into that, thanks! This must be new since like today or yesterday, haha

Pre installed backup and recovery works great if you're not rooted. Just make sure to check all boxes to backup. Store backup on computer, wipe, flash, root 253 then restore.
Sent from my C6603 using xda app-developers app
I had exactly the same problem and the only solution was downgrade to .434 with a full wipe!
Everything else I tried ended in restart because of the NFC update.
I could restore my system, because I rooted .434 after the clean install,
updated to .253 from [nut] and restored only the data partition from my last nandroid with recovery.
Then everything was as before and works fine.
But trust me, the only solution is downgrading with a full wipe! :good:
Did you try flash kernel/ otakernel from the .434 with flashtool if not try then
I will skip that update (cannot even get it from Sony PC Companion) so wait for 4.2
I dont use NFC and don't need whitebalance calibration.

My update keeps on failing.

I need serious help here guys. I have now updated my phone twice to the new Jelly Bean 4.3 ending in 136... every time I used PC companion and every time everything seemingly went well.
Every time it did a long boot and every time it said it was successful, but it still has the version ending on 290 when I go into my settings.
Ive reset and tried switching it off for a while it just won't change.
What is going wrong? Thank you!

Hi there... right so I have first tried to repair my phone, but still the new update just will not load.
I am now going to try your advice, but I have never flashed a phone in my life. I am reading how to do it now. I have downloaded the Emma flashtool, but now have to unlock my bootloader - I have heard previously that this breaks the camera... will my camera break when I do this?

You have to use Flashtool v9.14, not Emma, and flash the latest .136 FTF from Here for your Model only, you don't have to Unlock Bootloader, you phone will be just fine and your Warranty will not be voided.
Turn Off your phone, keep pushing volume down and connect via usb the phone to PC, keep holding volume down all the time, let windows install drivers for flashmode, open Flashtool, before that put the FTF .136 in flashtool folder, now click Flash on flashtool and select the right FTF, uncheck everything except Wipe Data, Appslog, Cache, now click Flash, Hold volume down until the green bar of the process will start at the bottom, now you can leave your phone alone. Done.

By clean install i mean that i have wiped data via flashtool and also in recovery before i installed the fw itself(deodexed one). So at first i used the new 199 over the last one without wiping, and i thought the reboots were caused by data mismatches. So I did a clean install. I flashed via flashtool the fw, flashed a kernel with recovery and did a factory reset there too, then istalled the deodexed zip via the same recovery. So i got to have the kernel flashed also. I am clearly not a noob. Now I have to check my apps, cause if you dont have it then the ony thing that is different on mah phone are my apps. I havent accepted any root premissions whatsoever on my clean istall, but i removed bloatware using TitBak. maybe I have deleted a system app that is nececery. But I was carefull this time. dunno mate
I get the random reboots as well but only when my phone is idle and it will reboot every few moments while idle...it happened after I flashed the 199 ROM from 4.1.2 (maybe I should had done one after the other) and get the won't charge bug from time to time (change to a cheaper USB cord let's it charge) random artifacts as well on the screen like a flash of text. So lots of bugs
