[Xperia Z1 General] Robert_1968_:
ta backup file corrupted, copy lost

here's the thing

I backed up my ta partition on my laptop and made a copy on an usb stick. The problem I ran into is that the backup file got corrupted somehow ( yes yes i tested it at first on a dry run), and I accidently formatted the usb stick (wrong one :().

now by trying to generate a new back up file it creates a ta backup file and on a dry run no errors found so it seems to be okay but I have serious dooubts about that

I unlocked the bootloader using the official way by sony

installed I hackers 4.0 beta with the doomlord kernel.

the big question is what about this newly created ta backup file

any thoughts or advice is welcome

:eek:
[Xperia Z1 General] SrMoure:
Sometimes you need to lose the data when downgrading , or when upgrading again. On top of that is the time you need to install 2 roms. Much easier to have a method as the one used for rooting 4.2.2 for 4.4.2 . Samsung phones are also easy to root. Therefore , I wouldn't consider easy to downgrade, root and then upgrade when there could be other methods as the one used to root 4.2.2. or methods used for samsung phones.
[Xperia Z1 General] gregbradley:
No, it's easier this way than trying to find an exploit, plus you do not have to install 2 roms, just one. The whole process can be flashed in 5 minutes.

If you unlocked them you last the drm keys on your TA partition. Any backup after that will not have them, so you have lost them forever.
[Xperia Z1 General] fer2503:
so if we unlock the bootloader in 4.4.2 (.757) what we lose? x-reality? bionz? other?
[Xperia Z1 General] 301stSpartan:
Just those two as far as I know. Just back up your TA before you unlock in case you ever want them back (or want to use your warranty)
[Xperia Z1 General] fer2503:
I read that with 4.4.2 we don't lose the x-reality
[Xperia Z1 General] 301stSpartan:
Not sure... haven't read that, but could be. There's also a thread for a mod to get it working again after unlocking, as long as you're in a stock based firmware. I use AOSP ROMs only so not really a concern to me personally
[Xperia Z1 General] ccelis:
Hi all just bought the z1 a few weeks ago and I'm planning to root. Just a question, will I be able to turn down the dpi on stock rom or will I get a bootloop? If yes, what's the best dpi on our phones? Thanks.

Sent from my LG-F240L
[Xperia Z1 General] 301stSpartan:
Yeah, once you get full root you can modify the dpi no problem. Personally I like 370

Latest kitkat fw doesn't break X-reality when unlocking bootloader. Confirmed by Sony
[Xperia Z1 General] [Fenix]:
Hello guys :)

I decided to unlock the bootloader of my Z1, but before I wanted to make a few questions

I apologize if they have already been answered, but I wanted to be 100% sure...

Before unlocking the bootloader I'm going to create a TA Backup: I have to do it on a specific firmware version? (I was going to prepare my phone with the latest version 4.4.2, 757, of nut)

For example, if I make a backup on 4.2.2 then, can I restore the same backup on 4.4.2?

To relock the bootloader, I must be on stock rom: so I will flash the entire ftf, for example the one prepared from nut to downgrade to 4.2.2, to be sure to have stock kernel right?

Thanks, hope someone will give me answer

Best regards
[Xperia Z1 General] gregbradley:
you can restore it on any firmware

No you can restore on any version, but unless you are running a stock KERNEL you will end up in bootloop, but that's not an issue, because you just flash a stock KERNEL to sort it

No, just flash a stock kernel. Flashing an entire FTF will do that, but that is overkill, just flash the kernel.
[Xperia Z1 General] [Fenix]:
Thanks bro now all is clear![emoji106]

Sorry i forgot something...if i unlock the bootloader will i lose some feature like camera or x reality?...i've heard of people that with a UB take bad quality pictures, is this real?

About x reality i know that it wont work on non stock based rom, but if i return on stock rom, it will work again?

[Xperia Z1 General] 301stSpartan:
If you restore the TA partition once back on stock, you will get all features back. Picture quality on ULBL is also quite good, though maybe marginally lower quality

I just rooted my phone and I'm a bit of a newbie here but getting a message saying it will power off after 15 mins of inactivity any idea how to deactivate?
[Xperia Z1 General] cingolat:
are you sure of this???? source???
[Xperia Z1 General] :
I forgot where my sources are but I've tested it. Trust me.
[Xperia Z1 General] cingolat:
so now with 757 firmware there are no difference with locked and unlocked bootloader? we don't lost any features?
[Xperia Z1 General] :
I know that we won't lose X-Reality. I'm not sure about the rest.
[Xperia Z1 General] 19manu91:
Sorry for the insecurity.. I'm on not rooted .534 Xperia Z1.. Can you confirm that i'll get root access simply installing the DualRecovery with option 3? I must use only the file "Z1-lockeddualrecovery2.7.121-BETA.installer" and not "flashable" right?.. After the installation of the recovery i need to install SuperSU simply found it on the market or in internet?.. Thanks..
[Xperia Z1 General] gregbradley:
Yes, google SuperSU.zip from chainfire and flash it in recovery (Or you can flash a prerooted ROM of your choice to update to 4.3 or even 4.4)

Please tell me how you were going to use the flashable version before you installed recovery?
[Xperia Z1 General] 19manu91:
Befor install a prerooted ROM i must get root access on .534.. right?.. maybe you mean that i can:

1) install DualRecovery with option 3 (--> so get root access)

2) install a 4.3 or 4.4 pre rooted rom (with SuperSU already in) ?

actually I have explained myself badly.. I wanted to say, i must use only the "INSTALLER" and not, first INSTALLER and after, with recovery installed, the FLASHABLE.. Thanks
[Xperia Z1 General] gregbradley:
I believe that's what I said....

Yes, just use one or the other, the flashable ones are to update dual recovery to a newer version if you have already got one installed.
[Xperia Z1 General] 19manu91:
I've got another problem with the installation. I'll connect the turned on phone with USB Debug and when i start the installer.bat, the program do all itself without ask me to press one of the 3 options (like the attachment image). Obviously the recoverys are not installed at the end of the process... what is the problem?..

UPDATE: It was a problem of my computer. putting the folder of dualrecovery in C:// it will be OK. I'll install the recovery and get root access. Now i must update to the last 4.4.2 KitKat.. can i direct upgrade to this or i must pass from the previous release? Thank you!
[Xperia Z1 General] gregbradley:
go direct to the latest version

2 step "fastboot.exe -i 0x0fce oem unlock 0xKEY" ----> it says FAILED remote: command did not succeed, But if i try one more time it suddenly says FAILED remote: Device already rooted. Any tips?
[Xperia Z1 General] andyjrobinson:
Have you by any chance unlocked and locked again?
[Xperia Z1 General] colors:
Yes, several months ago... did a reset thrue sonys software... so i had installed OTA updates after that.. 2 times and one time thrue computer. would be weard if something is from that time? or?
[Xperia Z1 General] andyjrobinson:
Well I had unlock and locked using flash tool, and now I get the same problem as you for a month or so now with no help or useful information so far.

Good luck looking for a resolution to this.
[Xperia Z1 General] colors:
Hmm ok :/ tried to downgrade now and root again with vroot. success.. but still no unlocking of BL
[Xperia Z1 General] gregbradley:
DO NOT USE VROOT, this information is all over xda, it seems your imei to China.

There are two possibilities, one, when you say reset, what do you mean, because resetting does not epoch your bootloader

2

Two, you need to set up a correct fillet path in flashtool to force flashmode unlocking not Fastboot, I will find my post about this when I get to my pc

If you have relocked your bootloader and want to unlock it again then please read this thread if you are having trouble

any ideas on this one,,,,,

I suggest relocking again using your TA backup and rechecking the service menu

Please tell me what it says
[Xperia Z1 General] colors:
tried to relock thrue flashtool and now mobile says "unlock bootloader allowed : yes"

Ta backup thing would be next attempt.. be back with results
[Xperia Z1 General] gregbradley:
No need, just do this
[Xperia Z1 General] colors:
Thats what i exactly did.. And Then i could unlock / relock thrue flashtool. But get stuck in trying tog Flash boot.img and If i does this step To unlock i get "rooting status unknown"
[Xperia Z1 General] gregbradley:
OK, restore your TA and try to unlock using fastboot and the instructions from the sony website
[Xperia Z1 General] colors:
It worked! TA backup did the trick.. having a unlocked BL now with root and omnirom 4.4.2. =)
[Xperia Z1 General] andyjrobinson:
So am I perhaps screwed as I accidentally deleted my backup and can't restore it?
[Xperia Z1 General] homer285:
use recovery software you should be fine.
[Xperia Z1 General] gregbradley:
Did you try the method of checking if you had the correct fillet structure and file.txt that I mentioned?

---------- Post added at 06:02 AM ---------- Previous post was at 06:01 AM ----------

Please read the whole conversation, this in no way will solve the issue this user has...
[Xperia Z1 General] Kyrius:
i have a rather strange problem with rooting:

After flashing NUTs 534 or any other stock 534 i can't root. Vroot says it's not possible, bin4rys get stuck right after checking if debuging mode is on.

It's really confusing for i had root before.

Even unlocking is now not an option because i can't backup TA.

Any ideas what could be wrong?
[Xperia Z1 General] gregbradley:
NEVER USE VROOT

If you read more you will see it sends your IMEI number to an ip address in china.

Once you have flashed 534 FTF, install dual recovery, then flash SuperSU.zip from chainfire.

You will then be rooted
[Xperia Z1 General] Kyrius:
i know about vroot.

Can't install recovery. Hangs at connect USB cable now. Doesn't matter where i plug it in (USB2.0 or USB 3.0). I'm on windows 7.
[Xperia Z1 General] andyjrobinson:
Hi,

Yes I have the file structure you mentioned and by accidently deleting backup I mean of the TA :(.
[Xperia Z1 General] gregbradley:
Uninstall all android/adb software from your PC

Then just install PCCompanion again and flashtool (Latest version)

Goto C:/flashtool/drivers

and run drivers.exe

Choose the drivers for flashmode, fastboot and for the z1

Then reboot and try again.

Let me know how you get on

Well, I think you may be screwed, but there is a new version of flashtool out, so try that,
[Xperia Z1 General] andyjrobinson:
Tried 1.16 that is what the log file is from on the other post

Also, make sure no other adb devices are connected

Please also post the last 5 settings in

[Xperia Z1 General] Kyrius:
Yeah, i know about adb. I always check if it's running and force close it if it is.

Attached are screenshots.
[Xperia Z1 General] [NUT]:
I know it can be a hassle but try doing that on a different pc, just for the sake of it. It could be the drivers are buggered. Are you able to test any other android device on this very pc? If so, try to use adb with that...
[Xperia Z1 General] andyjrobinson:
Would doing a software repair help me out with this?

Or is there no alternative methods to unlock consider the phone says unlock is allowed?
[Xperia Z1 General] homer285:
I think you cant.
[Xperia Z1 General] kingchristy123:
Can someone tell me if I can delete the ftf zip file from my SD card if I already installed it through recovery?
[Xperia Z1 General] gregbradley:
Of course, when you flash it, it pushes the files onto the system partition.
[Xperia Z1 General] dschneider:
I'm trying to downgrade from stock 14.3.A.0.757 to 14.1.G.1.534 so I can get root before upgrading back to 757.

However I'm getting the following error in Flashtool when I try to downgrade:

I've tried several 14.1.G.1.534 including the downgrade FTF in the first post as well as the FTFs found in the FTF Mega collection but still getting the same error everytime. If it makes a difference, the bootloader isn't unlocked and I have verified that using Emma. Any ideas?
[Xperia Z1 General] gregbradley:
update to latest flashtool
[Xperia Z1 General] dschneider:
I'm already using the latest flashtool from flashtool homepage which is v0.9.16.0.

After digging around, its mentioned in http://xdaforums.com/showthread.php?t=920746 that Xperia Z devices needs flashtool 0.9.13. Does that still apply?
[Xperia Z1 General] gregbradley:
Which phone do you have? The Z or Z1?
[Xperia Z1 General] dschneider:
I have the Z1. It's weird, I'm getting the exact same error message on both 0.9.13/0.9.16 Mac/Windows version with different 534 FTF files.

It always abort with error 0x80080012 when processing system.bin. I have no problems flashing stock 757 using Sony's recovery tool though..
[Xperia Z1 General] gregbradley:
Sony recovery tool?

You mean EMMA? That only works with unlocked bootloaders, but flashtool works with both locked and unlocked so thats not a problem

I suggest you uninstall all android stuff from your PC, re-download the latest flashtool from flashtool.net, install drivers and try flashing a re-downloaded version of a 534 FTF, they should work

Before you do that though, reboot, re-open flashtool and try again. then copy and paste the entire log from flashtool here please.

Don't connect the phone until it prompts you.....
[Xperia Z1 General] dschneider:
Nope, the recovery tool in Sony PC companion. Right, I will use another PC with zero Android stuff and try again. If it still fails, will get back to you with the entire log, thanks for helping to look into this.

Cheers
[Xperia Z1 General] neonboy:
Seriously, the only way to root Z1 is downgrade and then use that chinise crap?

Why back up the TA?
[Xperia Z1 General] Techpenguin5:
Nice tutorial thanks :) but is it possible to skip the rooting steps if you are on the latest fw(4.4.2) and unlock the bootloader. Then flash the boot.img from an aosp rom afterwards flash a aosp rom on top. If wanting a stock rom flash a stripped ftf.

just want to know wouldnt this above procedure work

[EDIT] Whoops im sorry i didnt realise you need root to backup TA
[Xperia Z1 General] lelinuxien52:
Backing TA partition is only necessary if you want unlock the bootloader. (with unlockable bootloader).

It allows you to backup and restore the original bootloader for warranty purpose for example or retrieving DRM keys.
[Xperia Z1 General] gregbradley:
I know that.

I was asking why the instructions given in the Quote said to backup the TA when there was no need to unlock the bootloader....
[Xperia Z1 General] ILikeTheWayYouMove2:
Install English version before you delete Chinese one as you need to give English version su rights, install what it tells you and exit

And done

I froze the Chinese one before uninstalling to be on the safe side

But it's been working good for me the past 4 days
[Xperia Z1 General] gz023247:
NO! The other way around mate, install English version and allow it to have rights etc, once done then remove the Chinese version ;)
[Xperia Z1 General] andymg350:
I was having trouble getting SuperSU to keep root after removing the Chinese super user, I've just tried again with kingo root that was mentioned in an earlier post and SuperSU seems to be working as it should now :D

Searched a bit around the forum for Kingo Root and in the Xperia Z forum it got some good comments and has apparently worked fine.

Tried it with my Z1 and it worked splendidly English regular SuperSU installed and working as it should.

If anyone else wants to try, here it is:

[Xperia Z1 General] RotteRotte:
Thanks for the tip -- actually what I needed. However I think I will wait rooting for a couple a weeks till things settles down a bit so exclude all risk for bugs, etc. It's a little scary that many people here experienced bugs and problems (read through the entire thread)..
[Xperia Z1 General] gregbradley:
There is no issue with rooting. Plus you can always unroot if you don't want it afterwards...
[Xperia Z1 General] RotteRotte:
Really? But what about the mentioned problems in this thread? Can you direct me to a guide for unrooting, please?

Thanks and cheers, mate.
[Xperia Z1 General] gregbradley:
I just re-read this whole forum and saw no mention of problems that were not caused by rooting. Only by those who did not know how to root or remove an app after installing it

As for unrooting, just hit the remove root button
[Xperia Z1 General] RotteRotte:
Ok, thanks for your help. Much appreciated. Any clear advantages for this over vroot? Anyone heard of Kingo Root before? Scared of them installing stuff on my phone I don't know about :)
[Xperia Z1 General] gregbradley:
Its in English and install SuperSU in English so you do not get the annoying Chinese notifications.
[Xperia Z1 General] Frakatchoo:
Kingo Rocks !
[Xperia Z1 General] SleemLDJ:
Sorry for a noob question guys.

I'm new to Sony after coming from HTC.

If I get this right,

1. Will I be able to root my XZ1 without unlocking boot loader?

2. Will I be able to flash recovery without unlocking boot loader?

Root apps such as titanium backup will work?
[Xperia Z1 General] gregbradley:
1 yes.

2 yes, but it doesn't work properly yet.

3 yes
[Xperia Z1 General] RotteRotte:
Point 2: I don't understand this :) Sorry for being newbie. What does flash recovery mean and why do I need it without unlocking the boot loader? Is this Kingo Roots problem?
[Xperia Z1 General] nobnut:
It has nothing to do with root.

In the 'old days', you would flash a recovery in order to flash ROM zips and other flashable elements, such as themes etc. In order to do this, you would have to unlock the bootloader.

HOWEVER, there are efforts ongoing currently to have a modified recovery (dualboot into CWM or TWRP) on the Z1 which does not require the bootloader to be unlocked. You will see from the thread that it is not fully working yet. This method has been used on other devices such as the Z.
[Xperia Z1 General] RotteRotte:
Thanks a lot nobnut. Btw, do you know if it's possible to check exactly what Kingo Root does with my phone? Check for bogus or possible exploit files, etc? Don't feel 100% secure :)
[Xperia Z1 General] nobnut:
I've no idea I'm afraid. Someone would need to decompile the exploit. I really don't think that there is anything to worry about. Just use common sense and caution when you download apps from unknown sources. If you wanted, you could install one of the various privacy tools to restrict certain app permissions (like location etc). Or you could even install Avast or similar. I don't bother with any of that stuff.

As far as root is concerned, like anything you flash, there is always the potential for risk. Nothing I, or anyone else can say, can ever fully reassure you (unless you produce your own root exploit). So, you either need to be prepared to live life with a little excitement, or just stay stock :)
[Xperia Z1 General] RotteRotte:
Ok. I tried with vroot instead and everything works. However, I want to uninstall the chinese Superuser and use SuperSU instead (like I did on former phones). People in this thread said I could uninstall via Google Play, but I can't find it there. How can I fulle remove it?
[Xperia Z1 General] nobnut:
It is easy enough, but for me it didn't work first time...

Basically, what you are trying to do, is to install another SuperUser app (English language) and once that app has root privileges, you want to uninstall the Chinese version.

So, whilst you are rooted (Chinese version). Download one of the other SuperUser apps from Google Play (I chose Chainfire's SuperSU). Then install it and open it. You will need to grant it root permissions (via the Chinese app) and it will probably nag you to update the binary. Follow the prompt.

Then in theory you should just be able to uninstall the Chinese app (using titanium backup etc). What ended up working for me was rebooting, having granted Chainfire's app root. Then I froze the Chinese version using Titanium. Then I checked root using another app (e.g. Root Explorer). Once I knew I had root, I then uninstalled the Chinese version.

No worries :)
[Xperia Z1 General] gregbradley:
Just use kingo root.

I have, its fine.There are no problems with it.

I don't know how else to tell you this...
