managedto get some sort or root but seems only temp root and wont let me flash a recovery because of this aaahhhh
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.

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...
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.

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.

As @gm007 said, it is advisable that you do a repair using SUS before doing anything else.
After that, if you're still on an older firmware (going by your signature) download any full .253 ftf (Find it here) and flash it in flash tool.
Ensure that you wipe everything when flashing.
Once you've updated to .253, root it & install 2.4 release dual recovery.
Then follow the instructions from here to update to .423.
If the instructions are unclear, just ask, I'll elaborate on whatever you didn't understand.

I think the problem is not the rom cause now i am on 4.2.2 leaked but this happened on others updates official
@kgs1992
Not to argue with you, as you seem like a helpful person, but why advise to update to 253 first, when they could just jump straight to 423 and root it with Doomlord's tool if they require root?

I'm not sure if there is a full ftf for update to .423, that's all.
And @[NUT] had advised an update from .253 or .307, but it seems the guide now says that you can also update from .350 or .434
I'm limited by my own knowledge, sorry.

Nobody needs to be sorry for helping others
There are quite a few 423 ftf available in the general section.
I used this version - http://forum.xda-developers.com/showthread.php?t=2336874
There are a few more for different regions/customisations posted in that section

OP is on neither of those firmware versions, but yes, using a full FTF for .423 there shouldn't be any problems coming from .407. The only potential problem could be if the ROM you're coming from contains a different NFC firmware and the destination ROM doesn't flash a compatible version. But since .423 does do this there shouldn't be any problems in this case
So i should install .423 via flashtool?

I'm not sure how the FlashTool process works. Does it wipe the data partition? If so there might be an option to not wipe it, I don't know. But if your device is rooted you can just back everything up with Titanium Backup (make sure to backup to external SD card) and restore the data for those crucial apps afterwards.

So far I've gotten 3-4 unexpected reboots on the new 4.4 firmware. Using different apps and the phone suddenly stops responding. Nothing works, not even the hardware buttons. Then after some seconds the phone just reboots.
Anyone else experiencing this?

I did. I had unlocked the bootloader and was running Cyanogenmod before. Did a complete wipe (data + cache) then re-locked the bootloader in order to let Sony PC Companion "repair" the phone by doing a complete reset.
If this keeps up I'll go back to Cyanogenmod.
Did you restore apps using titanium backup or any other app?

Hi.
I was running AOSP but I just wanted to go back to stock, so I followed a tutorial (http://forum.xda-developers.com/xperia-z/help/guide-how-to-revert-phone-cm-aosp-aokp-t2458530).
I'm currently on DoomKernel v18, Android 4.2.2 (10.3.1.A.2.67).
My bootloader is unlocked but I do not have backup of TA partition, is it still possible to re-lock bootloader?
Yes. Flash a stock kernel then use the BLU mode of Flashtool to relock the bootloader.

Would the C6603_10.3.1.A.2.67_Generic ES.ftf work?
and if it does i can update OTA after re-locking bootloader?
Yes, as the kernel is the same in all .67 roms. Just exclude everything but the kernel and don't wipe anything when flashing.
Edit - You should be able to update OTA, providing you haven't modified your software in any other way (deleting system apps, for example).

Okay, I noticed my wifi hadnt connected so i went into settings to turn it on. I press the little switch it goes blue then back to grey almost immediately, and then it says Turning on Wi-Fi but wont turn on. Bluetooth works fine and so does mobile data/service. not sure what happened but its a big issue as i only use wifi.
You shouldn't have any problems. I did exactly what I told you to my own phone with no issues.
Did you flash fota kernel from the FTF?
If you did, try flashing the FTF without wiping data. That will wipe /system and reflash it and should solve any problems. Note that you will lose root and any other system modifications if you do that.

I'm not near my PC at the moment, so cannot check, but when you're choosing what to flash, there should be an option to exclude fota kernel. Don't select it.
If all else fails, just do what I suggested and that should fix your issue.

There are check boxes that you select to wipe data and appslog. Make sure they're not checked and flash the whole FTF. That should fix the problem.
