[Q] Downgrade to .434? - Xperia Z Q&A, Help & Troubleshooting

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.

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.

You do realise that if for example your phone had TMobile ROM on it it will download the TMobile ROM in that tutorial. I have done it myself. I am with Telstra (in Australia) and I followed that tutorial and as soon as I flashed the ROM I downloaded I saw the Telstra splashscreen.

Just to clarify further. It would be three firmware. Three would be pised off if sony unbranded everyone lol. They have carrier agreements. So your ftf would be three branded

I am afraid I am a noob here on that. I had just followed the tutorial to the T and created a FTF that can be flashed with flashtool. Been using this for the past two weeks when ROMs can't be rooted/CWM can't be installed.

All I'm saying is that I followed the tutorial word for word and VipeR lx is right when he clarified things up that if your XZ is branded you would still get the downloaded ROM branded, just like what happened to me. Luckily there's a unbranded ROM for Australia which made it possible for me to de-brand my XZ. I do have the Telstra ROM saved so if ever I had to send it away for warranty repairs I can always flash the Telstra ROM back.
Me too. I used the update services software to download. After downloading the file and flashing with flash tool, there is no indication that this firmware is linked to any Telco.
Maybe if someone can flash and report?

Strange, bro.
Did you even manage to get into the setup? 5 steps to setting up your phone? I had that demo video. but after setting up the phone, all is well.
I had tried this firmware a few times after installing ROMs that are based on the 434, as somehow, I lose 3G with these ROMs. I couldn't even root the phone with the method described.
So I flashed back to the stock 350 firmware and root the phone and install the CWM recovery in the phone again.

I wanted to debrand as mine is attached to SingTel. I flashed this over my existing setup and didn't do a wipe. Now it has screwed up that I can't turn the screen off at all (finally I killed that some demo application and off now). Luckily didn't loose data except the home screen setup.
I will have to reinstall the whole thing tonight.

U did flash with flash tool and not recovery right? If you do flash with flash tool, all data is lost.
I think this is unbranded as the apps from M1 which I got this phone from is not present in the FTF after flashing with flash tool.

Who knows maybe the M1 apps in your phone was not integrated to the ROM and it was only installed on top. I can't really tell. I just know that when I did the tutorial I still got the Telstra ROM.
Also using the Flashtool you have a choice of wiping data if you don't untick the boxes before you flash.
EDIT:
There is the
(FTF) C6603 10.1.A.434 Cust ID 1270-1412_R6A Singapore available in that thread. The handset apparently is from M1 so I'm not sure if it's branded or not.

No don't remove the thread. If you didn't get M1 apps after following that tutorial then the M! apps must have been installed on top of the ROM that's probably why you never got any M! apps when you reflash.

I flashed with flashtool and there is option not to wipe.
This firmware is confirmed not the generic as I have seen this SI/CDA number in the demo set. Retail sets (so far I've seen) begins with 1270, but if you notice this begins with 1272. Moreover, none of the retail sets will run the "demo" video when you start your phone and worst is that it won't let your phone to switch off the screen.
I don't know how you ended up with this firmware on your handset!

Alright I am new to the XZ, i use to have the X Play a long time ago, but havent messed with BL unlock, flashing, rooting or anything in awhile. I had a question, if i unbrand my TMobile XZ to an unbranded version, will i then be able to unlock my BL? Or does that remain unlockable regardless?
Hi before you do anything make sure to perform a backup of your DRMs via Backup TA. Then you are free to do whatever you want.

you should do a

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.

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

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.

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.

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:

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

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.

[Q] XZ Re-lock Bootloader without TA

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.

Should I root first
No. You don't need root to use Flashtool.

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.

No, It flashed
kernel.sin
rpm.sin
loader.sin
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.

same issue :/
didnt really understand what you meant with the without wiping data thing, sorry.
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.
I'm not sure what has happened, as I have done exactly what I told you before and my WiFi works fine. :/
