Try another root explorer like root file manager app from store.
If you insist the fixing problem on the app which you are using,

i had the same issue, i posted a new thread asking about this but all i got was some funny solutions like reboot your phone, blink with your left eye ... etc.
so here is what i did to fix it
1- restore (the normal restore from backup & reset option on the settings) the whole device again after backing up all my data and removing the external SD card.
2- with the root still exists i rerooted using this method (Root MANY ANDROID!)
3- i installed all my apps and settings again manually to assure that there is no conflicts with the previous backup.
4- everything went well now

[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 can start up my phone with .253 firmware, but not really with .434 ('semi-bootloop due to 'NFC update')

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...

Which backup do you think is the best? Pc companion/the pre installed 'backup and recovery' app/Carbon/adb full backup? Does any of these guarantee a full backup? I want to be sure before I try..

.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.

[Q] Can't root .434 after downgrade

Hello!
This is my first post, and I hope I'm not starting with posting a question already answered millions of times. I Tried googling and looking around on this forum, so if it is a double post I'm counting on forgiveness
I have a C6603 Xperia Z that I managed to screw up my root after updating it. After starting to miss my root I searched the web and ended up here. I used the guide called [GUIDE] [ROOT] xperia Z .253 fw [Locked&unlocked bootloader] and flashed my phone down to .434 with the file C6603_10.1.A.434 AU_Unbranded.ftf.
Wiped everything, data and chace included just to start fresh. Tried using the EasyRootingToolkit by goro_khun like the guide I found said, and it was the one I used to root my phone without any hiccups when I first bought it. Now then, here comes the hiccups that have stopped my fun this time.
It won't root my phone, and I have no clue why. The easy rooting toolkit runs just like normal, and it concludes with my phone being rooted. If I check my phone with a "root checker app" they all end up with the conclusion with my phone not being rooted. Only thing I found that changes when I run the toolkit from a fresh install of .434 is that the "bootloader unlock allowed" in the service menus changes from yes to no.
So please help a n00b with this stuff, otherwise I can't continue on my path to getting a rooted .253

Try this root method

Tried this method, and no luck. Only thing I see that looks out of the ordinary is that one of the steps in the root program seems to fail.
it says
"Cleaning up
rm failed for /data/local/tmp.su, No such file or directory
Ok rebooting lets hope it worked!"
(after it have installed busybox and everything, like my cut out says its when it starts to clean up).
Other then that I don't get any error messages or anything. Anyone have a good idea on what I can try? Any logs I can cut n paste to help you guys out figuring out what I'm doing wrong?
I'm using option number 3 on this root program, since it says it's the one for xperia Z, counting on that one to be the right one.

Unable to update .244 from OTA for my Xperia Z

Hi,
I am not able to update my XZ to the latest .244 firmware. Here are some info of my Phone.
1) locked bootloader (it is unlockable)
2) current on .423 firmware.
3) rooted
4) install superSU (with survival mode on)
5) install OTA rootkeeper.
I saw some post stating that they are able to keep root after OTA, so i am hoping to keep my root too after OTA.
please advise.

I have exactly the same problem. Cant do OTA and im states scared to update through PC companion since my friend bricked up the phone.

Are you running stock .423 odexed? I had this issue when I flashed a deodexed ROM then tried OTA update
Sent from my C6603

Hi,
It is not possible to do a OTA Update after deleting one or more system apps (even stuff like partnerbookmarks).
There are, however, 2 ways to get the Update.
1.) Follow some of the instructions here like this: http://forum.xda-developers.com/showthread.php?t=2287149
There are some other ways posted here at xda. They use the flashtool to flash current firmware.
2.) Use Sony PC Companion, this will work ALWAYS,but: Root will be gone. U can use Doomlords rooting method to get Root again:

PC Update will never fail, the only thing is that you lose root access, which can be easily recovered though.

Hi mate, dont panic. Just follow the instructions on how to flash a stock firmware with flashtool. This is already described here at xda, try searching for it. It will repair your phone but data may be lost.
