FlashTool 0.9.16.1 Ubuntu with kernel 3.11.0-26

phone is brand new as said, nothing installed/done yet.

I already tried redownloading the 14.1.G.1.534_NUT, didn't help.

The phone is starting with the 'tutorial&accept our stuff' after rebooting...

Anything I'm missing?
[Xperia Z1 General] gregbradley:
turn on USB debugging.

Also, just update to the latest 4.4.4 firmware and then root it.

I suggest you just repair the phone using Pccompanion. If it updates to 4.4.4 then just root it using the newroot tool. If it does not update to 4.4.4, enable usb debugging on the phone, install drivers on your computer and flash a 4.4.4 FTF and then root it

[Xperia Z1 General] kefi999:
I need help,i did all things above work perfect and since we downgraded to 4.2 i can root and back and NOT unlock bootloader,i went to sony site and they tell me there i need minimum of 4.3 android i tried upgrading thru update service but it doesen't work and they say if i unlock it earlier version like mine i wont be able to use camera what to do now ???
[Xperia Z1 General] gregbradley:
Use pccompanion.

All variants of the xperia Z1 have an official update to at least 4.3
[Xperia Z1 General] kefi999:
will i lose root ?
[Xperia Z1 General] gregbradley:
Yes,

but then you want to unlock the bootloader so you will get root back when you do that and flash a custom kernel

Otherwise, what's the point in unlocking the boot?
[Xperia Z1 General] kefi999:
tnx bro ITS DONE !

Hey, I have found a way to unlocking band for our phone. Currently I only tested with 6902, not having 6903 or 43 so anyone want to test PM me. If my process was right, you should have option to choose which band works for your country, dont need to buy other variants (Except 6902, no lte :v ):D:D:D:D

I have made a thread in General section to post my guide (If my process was right and work for all variants) so this commment is for tester invite only

Does Somebody knows something about unlocking bootloader unoffically?
[Xperia Z1 General] gregbradley:
Yes, it is impossible
[Xperia Z1 General] :
sad

Then somebody knows, how i can boot custom kernel with locked bootloader?
[Xperia Z1 General] gregbradley:
No,

It says no because you are not allowed to do it, and since there is no unofficial unlock you can not do it

anyone unlcoked bootloader of sony xperia devices by kingo ?
[Xperia Z1 General] gregbradley:
No, kingo does not touch the bootloader.

The only way to unlock the bootloader is the official method (Or use flashtool which automates the official method for you.)
[Xperia Z1 General] Jounsa:
Hello,

If I was to unlock my Bootloader and then restore my ROM from a nandroid backup, would my phone's bootloader be relocked?
[Xperia Z1 General] dedei:
If you re-unlock using flashtool, it's possible to relock the bootloader using the TA image and stock kernel of the nandroid backup, I did that numerous times already.
[Xperia Z1 General] gregbradley:
Restoring the TA image obviously relocks the bootloader. Restoting a nandroid backup does nothing to the TA partition so can have no effect on the bootloader status

Hi there

I have this annoying problem with unlocking bootloader.

bootloader unlock status is allowed, all drivers installed and reïnstalled, tried it with command line and with flashtool but no success

command line fastboot -i 0x0fce oem unlock unlockkey gives me remote command did not succeed

fastboot devices gives me my device id

getvar gives me 0.5

trying with flashtool gives me a unlock ok but it isn't when trying to flash a kernel it says remote command not allowed, when trying to hotboot it gives me too many links

searched the internet but couldn't come up with a solution for this issue, I know there are more people having those issues.

can anyone think of a solution.

thanks in advance.

Help a noob with rooting Xperia Z1

Hello,

I am trying to root my Xperia Z1 and afraid of bricking the device. I checked some posts and videos but I am looking for the latest root information, since I was unable to find relevant and complete information. I also downloaded the EasyRootTool kit v12.4 but when I try to extract it I get this error message: The archive is either in unknown format or damaged.

I also watched this video: [NEW] Xperia Z1 ROOT solution for Locked Bootloader Android 4.4./2/3/4 (C6902,C6903,C6906,C6943) by SHEM (Przemysław Orawiec)

But the files have been removed. I would appreciate if someone experienced and professional can help me in rooting the Xperia Z1. Here are the phone details:

Model number: C6902

Android version: 4.4.4

Kernel version: 3.4.0-perf-gaee6e5a

Build number: 14.4.A.0.157

Any help will be appreciated, thanks

Vroot for Android

If we search on internet about rooting apps, we will found unlimited apps which hold large numbers of fan following and on also hold the top position on google, but it is difficult to choose the best one. Sometime most applications which are on the top of google search results include with suspicious threats, therefore before choosing any rooting app be careful and read almost all the stuff which is include in the article.

Before applying rooting apps on your mobile phone, never forget to take backup to keep safe your mobile stuff. If your mobile is on warranty, don't ever think about to root, because after rooting your mobile, you will not be able to claim your mobile warranty.

I also shared different rooting apps on my blog, but here i am sharing APK file Vroot. Which i think is the best to root. You need to just download the APK file, after downloading, locate on your mobile phone and launch. Just follow onscreen option to complete installation.

Root your mobile easily with a simple click. Just go with this link.

If Superuser have any setting files or log files anywhere else, please tell, so that I can remove everything.
