Hi, how to uninstall the Chinese version of SU, and install the English?

Ok. Problem solved. He helped SuperSU. Root I need to link Folder. Works.
[Xperia Z1 General] Laleschland:
Until now i haven't flashed with flashtool except my HTC Flyer, so i don't prefer this method.

My XZ1 is rooted but the bootloader is locked. Actually i just have to plug in my phone via usb and reinstall the firmware via Sony update Service, am i right?
[Xperia Z1 General] Chillout:
I guess the original post needs some updating to make it all clear...

- VRoot doesn't work on .290

- Bootloader unlock DOES work on .290
[Xperia Z1 General] Ferranza:
does kingo root work on 290?
[Xperia Z1 General] gregbradley:
OMG.....Apart from the fact NO, try reading or try doing it yourself.....FFS
[Xperia Z1 General] Ferranza:
Many thanks Master for your fast and NOT kind reply... I will read your thread..................oops it's closed
[Xperia Z1 General] gregbradley:
Yes, I closed it. I am working on it. Remind me not to help you again.
[Xperia Z1 General] Ferranza:
Thanks, this is the right spirit from dev to noob! You must be proud of you!
[Xperia Z1 General] Snaqejack:
So what's the plan, to release a flashable zip, or some kind of program to root our phones?

Thanks for your hard work by the way!
[Xperia Z1 General] gregbradley:
The plan is to work on the current kernel. When the sources are released it will help, a lot!! In the mean time a root method may be found but it seems unlocked bootloader and advanced stock kernel is the best hope so far.

Please be patient..

waiting for 4.3 rooted

Hope we have root on 4.3 before Xmast :)
[Xperia Z1 General] ravi_buz:
We already have root. It's just not a straight forward one yet
[Xperia Z1 General] rodpgfx:
Hey Ravi I noticed you commented that we already have root for z1 with .290 update........Is it in this forum? I can't find it.

I tried the vroot and the Root with restore, doesn't seem to work for me

Is there another one?
[Xperia Z1 General] gregbradley:
Look in the development threads
[Xperia Z1 General] patwang0311:
Yes, confirmed root method from development thread works. Basically just unlock boot loader (no, won't break camera anymore with 290 firmware), flash a kernel with recovery (I opted for stock with Philz recovery as I am using pure stock Rom), flash supersu zip and that's it. Very trivial.

Double checked kernel having exactly the same build signature as stock. After couple of reboot still able to update hosts file with adaway, my backup root still runs on schedule, Android firewall can still apply rules, widget locker can still hide away the navigation button pane, .... ---> root still works.
[Xperia Z1 General] reposed:
Here is a very good break down of what is needed to root 290 firmware:

techbeasts.com/2013/12/19/install-cwmtwrp-recovery-root-sony-xperia-z1-c6903-running-latest-14-2-0-a-290-firmware-how-to-guide
[Xperia Z1 General] rodpgfx:
Can anybody confirm that this works with 6906 also? Or do I need a different kernel than the one here?
[Xperia Z1 General] RHBH:
Try it, but exclude the baseband, and in the end flash the baseband only from a C6906 .290 FTF (I saw one from generic Canada).

Has anyone had any success rooting DoCoMo Xperia Z1 (SO-01F)?

---------- Post added at 03:01 AM ---------- Previous post was at 02:55 AM ----------

What harm might be done to my DoCoMo Xperia Z1 (SO-01F) if I were to attempt to flash a "global" firmware via FTF?
[Xperia Z1 General] RHBH:
I don't recommend, you may harm your device permanently.

Japan devices usually have different ROM and Kernel from the global devices.
[Xperia Z1 General] undecim:
Thank you RHBH. I was afraid of that. Your advice is sound and solid.
[Xperia Z1 General] VyZard:
Hey guys, I just bought an xperia z1 3 days ago, coming from an iphone, and since i live in France the OTA for 4.3 hasn't arrived yet I flashed a nordic .290 firmware, working perfectly, but now I"d like to root my phone cause I want to install the romaur custom rom. But apparently he prefers a "phone rooted with cwm", so I've done some research but couldn't find a way to root it without unlocking the bootloader. So here's my question (since I can't post in a Dev thread): do you think rooting with cwm is an absolute requirement? Or can I use another method, and not unlock my bootloader? If so, which one works with the current firmware?

Thanks guys, hope I'm not bothering!
[Xperia Z1 General] gregbradley:
Welcome to the real world

There is a reason for that!!

Yes, you need to be rooted with CMW, but if you want that rom you can downgrade to 534, root, install CMW then install that rom. You can do all this without unlocking the bootloader.
[Xperia Z1 General] VyZard:
The sarcasm is expendable, but thanks for your answer.

So if I dont want to.downgrade I'll have to unlock the bootloader, or am I stikl gonna need to downgrade?
[Xperia Z1 General] gregbradley:
The installation instructions are on the OP of the ROM.

You need to be on a ROM with recovery, so you have 2 options

1) Unlock your boot

or

2) Downgrade and root
[Xperia Z1 General] VyZard:
Thank you for your answer and time. I'll unlock later, maybe Ican unlock, root, and relock... Or not. I'll see. Thanks.
[Xperia Z1 General] gregbradley:
that can be done but you will lose root, the point of unlocking is to flash a custom kernel with root, once you relock you cant boot on custom kernels, you will end up with a bootloop until you flash a stock kernel
[Xperia Z1 General] timberwolf60:

I see. Well I dont have much of a choice then. So why is it that previous versions didnt need cwm root and you could use vroot or else? Simple curiosity.
[Xperia Z1 General] DefunctiO:
They promised us peace and love and what did we get? Vietnam...

Well, those FW are quite new and one click root has not been developed yet. Why? There are different expoits (old ones were patched up) and it seems like it is harder to find this one click wonder solution now.

Or, they are just lazy and don't care about Z1...

disclaimer - my opinion only... (humble)
[Xperia Z1 General] fqarrieta:
Hi, I have a question, when you unlock the bootloader on 4.3 still loses something? since the camera works well.

Excuse my English.
[Xperia Z1 General] VyZard:
I see... Well reading I understand that if a one click root was to be released I could use it instead of cwm... But do those root methods install dual recovery?
[Xperia Z1 General] abbychauhan:
Dear All,

Sorry for noob question.. I have updated my Xperia Z1 to 4.3 via Sony Pc Companion.. But Now What?? I mean I want to root now.. Can someone tell me how can I Root now step by step.. Really like to enjoy Custom ROM'S also I like to backup my TA Partition.. But for all this I have to Root.. Can someone enlighten me with the knowledge.. Thanks in advance..
[Xperia Z1 General] gregbradley:

I think you are very confused and you should try to read a bit more. Cmw is a recovery, root is different.

[Xperia Z1 General] rodpgfx:
Guys I might be a little off what you're talking about right now, but I am a junoir member, thus not allowed to start my own threads....

I have the xperia z1 which i am flashing the .534 ftf file to right now.

In the service part of the phone, it says i can't unlock the bootloader. Am I stuck with this factory rom, or can i still flash custom ones, and custom kernels?

Thanks guys for all the help and especially those who I have been PM'ing
[Xperia Z1 General] abbychauhan:
Dear Sir,

You guys are very advance, half of the Quotes you guys are saying i am unable to understand.. Can you Tell me STEP BY STEP procedure.. Like download this then do this.. then press that button.. then go to recovery by pressing this button.. you know something like that..

Sorry in advance for my NOOBNESS.. and thanks in advance.
[Xperia Z1 General] dlads:
Apparently you won't be able to unlock your bootloader, youre in the same boat as me as i'm also unable to unlock mine too.

Custom kernels and the like will not work on your handset and a few other bits n bobs, plus there was a problem with 4.3 roms and locked bootloaders and full root access.

If you do root and upgrade, i'd personally stay a 4.2 rom until it's made stable.
[Xperia Z1 General] abbychauhan:
Well thanks for the reply atleast Someone is truthful..
[Xperia Z1 General] gregbradley:
I don't see that information, he may well be able to unlock, he has not said what his bootloader status is yet

---------- Post added at 07:29 PM ---------- Previous post was at 07:27 PM ----------

I have been truthful as well, just fed up with answering the same question 30 times a day
[Xperia Z1 General] alankstiyo:
Cant root with vrooton 4.3, is there any other way to do it?
[Xperia Z1 General] dlads:
Spotted that, soz about it, was talking to someone else at the same time, i ment to write "May not be able to" so apologies for that [MENTION=5618877]abbychauhan[/MENTION]

I've noticed that youre a bit short in all fairness Greg, you can be helpful and nothing wrong with answering posts but if it gets your back up then why do it?
[Xperia Z1 General] gregbradley:
I am asking myself that more and more recently.

I enjoy helping people learn (in real life I am a teacher) but is so annoying to see people just asking the same question that has been asked and answered several times already in the same thread.

There is also a lot of people giving wrong information that's not helping.

I have been on these forums for 3 years helping and I have never known it this bad.

You have to remember I get dozens of pm's a day as well. I am a great believer in enabling people to learn, not just giving them monkey see, monkey do instructions.

That way people learn more, this is after all xda developers not xda customer services.

I will post a link later that explains it better about what this site is about.

I think I may take a long break from the Z1 forum and just support the other Xperia devices where things seem a lot more sensible
[Xperia Z1 General] dlads:
Yea i'm with you there, i don't often give wrong info, I was at work and busy and rushed a reply, i'm kind of like that myself with helping people, just check out the s3 forum and you'll see what i mean.

I think the influx of people not knowing what to do is because of the Z1 itself, for the sony faithful it's a normal day in the office but the Z1 is a different breed compared to anything i've ever used before and it's the best i've seen from Sony in years, hence the change, i mean i've got my head around it now but i can understand how people could get confused.

Take it with a pinch of salt, no point getting down about it, just plod on an smile ;) It's easier, either that or i'd be going mental in the job i do, the public generally have very little idea what to do with a phone and literally 90% of the people i see have never even heard of XDA / Rooting, a good chunk of them leave their phones exactly the way they were bought, which kind of defeats the object of getting an android handset.

It annoys me but it's just not worth getting bothered about. :)
[Xperia Z1 General] gregbradley:
Yes,

I was not referring to your previous post about mi-information, there are several people on here who clearly do not know what they are saying and just giving out wrong information.

As for the purpose of what we are here to do please read this. It sums it up nicely.

I have been fortunate enough for my efforts on this forum to be recognised, hence the title of "Recognised Contributor" but currently its hard to wade through the garbage posts to actually be able to Contribute anything worthwhile.

EDIT

And the success of the Z1 is part of the issue, the fact that the phone is so good is bringing people who have been Samsung and HTC fans to the Sony Xperia lineup, and Sony phones are very different, but the information is there.

See you all in the New Year.
[Xperia Z1 General] digitall1982:
can someone confirm that root is still available after OTA update from 4.2. to 4.3 ?

i will not update via pc companion if that is true

tnx
[Xperia Z1 General] abbychauhan:
None taken.. i know you guys are helping only.. and i said you are truthful because i searched all internet just to find proper ROOT procedure for Z1.. People are telling do this and do that but they should know people like us who dosent have such knowlage are unable to understand and we cant do that Tricky work on our Phone(Due to Lack of Knowledge).. So I like the Answer "That Apparently you won't be able to unlock your bootloader," because its better not to f**k up my phone and leave it be for some time till better solutions come..

Whatever thanks for Everything
[Xperia Z1 General] AhhEff:
OTA Update from 4.2.x to 4.3 and keeping root is a fairytale at this point.

4.3 is rootable. But its a little bit tricky at the moment. Includes unlock bootloader and other stuff.

I did it and it works fine but i only know a good "How-to" in german language.

Xperia Z1 Vroot Asking Password

Hey. Thanks for the post. But I have a problem with the VROOT. The software recognize the phone (Sony Xperia Z1 C6902). When started the root process, the phone display start to smoothly flashing, and then, a screen saying that some software has requested for full recovery. Ask weather allow or not, including a password field. Then 2 buttons saying dont recover, and recover now. While, the vroot shows a similar screen and specifying that press the recover now. Although I press it, nothing happens, then the root process fails in the vroot. Apparently there is a button that says something like retry, but the problem is still there. Could you please tell me if you have face this problem before? And how to solve it? Thanks for the post and the help.

I'm stuck

Hi guys, first time posting, just got an Xperia Z1 with the intention of rooting it and installing CM. However, I've run into a small problem.

Right so in my understanding, the TA partition is pretty ****ing important. I've updated to the latest software on my Xperia Z1 which is 14.1.G.2.259. Now with this software, I can't root my phone, and because I can't root my phone, I can't backup my TA. The only other way to root my phone is to flash an old update, but that will rid my TA partition. So is there a workaround or something for this because I've been researching all night and I haven't found a solution to this problem of mine.

Thanks guys
[Xperia Z1 General] gregbradley:
That is the way to do it. It will backup your TA correctly on whichever version FW you are on.

Downgrade, root, backup TA, unlock bootloader, flash doomkernel*, flash CM.zip

* Or any stock based kernel with recovery, this step is only included so you can get a recovery, there are other methods
[Xperia Z1 General] Frewy:
So to be completely clear I will not lose my TA on downgrading to a rootable firmware? And where can I find a guide for that?

Thanks man
[Xperia Z1 General] gregbradley:
No, you wont lose TA (Your phone MUST have it and it is outside the system partition)

To downgrade is as easy as installing the flashtool from flashtool.net and flashing a .534 FTF file that you can find in the mega collection thread
[Xperia Z1 General] Frewy:
Alright, thank you very much for your help :)

Unable to root with VRoot.

- Running 4.2.2, 14.1.G.2.257.

- Tried both MTP and MSC.

- USB Debugging is on.

- I am on Windows 8.1.

- Drivers are installed properly as VRoot can still detect it.

- The other root software won't bother installing because my PC is in English.

Any ideas? I really want to root so I can back up my TA so I could unlock my bootloader. Thanks :)

Nah. I'm just gonna reflash to the latest 4.3 after backing up my TA. Then i'll unlock my bootloader, flash Doomkernel and then flash root.
[Xperia Z1 General] VyZard:
Hey guys! first: merry christmas to you all ^^

got a little problem here: i tried to flash monxDIFIED rom for 4.3, FW.290, got a locked bootloader, never rooted my phone etc.

I was a little confused on which steps to follow so i took the ones that were closest to my situation (steps below). But there's also a "locked and unlocked BL" section that says other things...

I followed the steps and got bootloops, must've read something wrong so flashed .534 again, everything working, and did everytthng once again, TO THE LETTER:

"LOCKED BOOTLOADER

BACKUP any critical data to microSD

Copy this rom zip package to microSD

Flash stock Sony's firmware (FTF) 14.1.G.1.534 using flashtools if u r not currently running on this fw version

Root using any available method (VROOT recommended)

Install ONLY THIS recovery (TWRP) unpack & read readme.txt for instructions | check for superuser prompt (if any) [vroot is using its own supersuser app]

Reboot in recovery, do factory reset & install rom until finish

Skip (x) steps if u already running same base firmware with latest monxDIFIED base rom. Else, proceed.

(x) Turn off device. (Hold power button + vol up until vibrates 3 times) [or use recovery turn off device option, if any]

(x) Flash latest Sony's firmware (FTF) matching current latest monxDIFIED base rom using flashtools. Uncheck all WIPE options and exclude all EXCEPT KERNEL & BASEBAND to get latest matched kernel & baseband.

(x) Turn on phone. Done. "

I unchecked all wipe options and checked all under "exclude" except kernel and baseband. I used a ftf that I know was working cause i have been using it for a week, waiting to flash a custom rom.

On flashtools, everything seemed to work, no errors etc.

Now, the phone won't turn on again... so please guys, help me :-/, really sorry for the inconvience.
[Xperia Z1 General] TagEHeuer:
== Downloads ==

- Download flashtool for you operating system from the official FlashTool site: Download FlashTool

- Download the XZ1 device folder I created: Xperia Z1 device filesWill upload this later

== Installation ==

- Run the installer or unpack the archive for Linux and Mac

- [Optional] Windows uers can go to C:/FlashTool/drivers to have a nice wizard to install fastboot & adb drivers and also drivers for other devices

- Copy the downloaded device file archive to C:/Flashtool/devices

- Open up flashtool, go to "devices => manage => import" and choose the device file you downloaded

- Installation finished!

Regarding the red parts;

Obviously the download link hasn't been supplied, if you use C:/FlashTool/drivers to try and download any drivers to add to the FlashTool on WINDOWS 8, it will not allow you. Microsoft have restrictions where it won't allow the drivers to copy over from the tool. There is NO way round this as far as I have found.
[Xperia Z1 General] VyZard:
Can somebody help me...? :-/
[Xperia Z1 General] Frewy:
Right, so I've downgraded, rooted, backed up my TA, unlocked the bootloader and then installed the generic australian 4.3 update to fix the camera, but now im clueless on what to do for the Doomkernel. I've looked around but nothing has made much sense nor can I find a download link for "Doomkernel" any ideas?

Thanks
[Xperia Z1 General] caqo71:
For windows 8/8.1 you have to restart windows with digital signature for drivers turned off. There is some posts explaining this procedure and flashtool works very well. Don't say that it's impossible, or there is NO way round. By the way, I have windows 8.1 have no trouble with flashtool

cheers. :o
[Xperia Z1 General] :
There is a way. I'm on Windows 8.1. If you really did Google, the first option has the answer. Plus it's from XDA too.

-------------------------------------------------------------------------------------------------------------------------------------------

Click here for DooMKerneL. Download link is at the bottom of the post. You'll see it under [ downloads ].

You'll need fastboot or flashtool to flash DooMKerneL. Just Google it.
[Xperia Z1 General] Frewy:
Does my phone need to be rooted? Because I can't root 4.3, and I tried before to downgrade to a rootable firmware, only to get stuck in a boot loop. I restored it to 4.3 with no problem.

Tl;Dr does my phone need to be rooted to flash doomkernel?
[Xperia Z1 General] :
No. Your bootloader needs to be unlocked. However unlocking bootloader means losing your TA. I recommend you to downgrade and try to root again. Then backup your TA. Go back to 4.3, unlock bootloader then flash DooMKerneL.
[Xperia Z1 General] Frewy:
Ah yes, my bootloader is unlocked, and I backed up my TA, did that before upgrading to 4.3. So after I install doomkernel, do I just continue with the CM installation as per usual and then restore the TA?
[Xperia Z1 General] :
If you want Cyanogenmod, then all you have to do is flash the kernel located in the zip file of Cyanogenmod. Then flash the Rom and Gmail though CWM. DooMKerneL is for stock Roms. You can't restore your TA. I heard it'll brick your device. Only restore when on stock.
[Xperia Z1 General] Frewy:
Alright then, but what's CWM?
[Xperia Z1 General] :
It's a recovery. Most custom kernels have them. You boot into it and using the vol button to navigate through the menu. With a recovery, you can flash Roms or mods that are in .zip files. Google for more info. Currently eating.
[Xperia Z1 General] Frewy:
Can I install CWM without root if my bootloader is open?
[Xperia Z1 General] :
Some kernels have CWM installed. So you can install CWM without root by flashing kernels. However you need root if the kernel use have doesn't have CWM. Stock kernels don't have CWM. Only Custom kernel and most stock-based kernels.
[Xperia Z1 General] Frewy:
How would I know if my phone has CWM?
[Xperia Z1 General] :
When you boot up, there's usually a vibration or led indication on the boot logo (SONY logo or a custom logo). Then repeatedly press the Vol Up or Down (Can't remember) and it will boot into CWM or TWRP. TWRP is basically CWM but allows you to use the touch screen to navigate.
[Xperia Z1 General] Frewy:
Yeah none of those worked, pressing down put it into safe mode. So I have to root the phone to install CWM yes?
[Xperia Z1 General] :
If you have unlocked bootloader, you can just flash a kernel that supports your rom and has CWM. You don't need root.
[Xperia Z1 General] Frewy:
But my phone doesn't have CWM?
[Xperia Z1 General] :
So flash a kernel that has CWM. DooMKerneL has CWM.
[Xperia Z1 General] Frewy:
Ok so flash doomkernel, then install CM through CWM.
