You want CM? Okay then download CM. CM have their own kernel in the .zip file. It's the boot.img. So flash CM's kernel. Don't use DooMKerneL.

In other words, DooMKerneL is for stock-based rom. It won't support CM. That's why CM have their own kernel in their rom file.
[Xperia Z1 General] Frewy:
So how do I go about doing that? I'm sorry for asking so many questions I'm just trying to make sure I don't **** up my Xperia
[Xperia Z1 General] :
- After you download the latest CM Rom, extract the boot.img from the zip file. The boot.img is the kernel you need.

- Put the Rom (.zip file) and Gapps into your SDCard

- Flash the kernel with Flashtool.

- Once done, reboot into CWM. (When there is a vibration or led light on the boot logo, press the volume up/down repeatedly. Don't hold. Press repeatedly)

- Wipe data/cache

- Flash the CM Rom (the .zip file you got when you download the CM Rom)

- Flash Gapps

- Reboot

Don't understand how to flash? Just ask. We're all here to help.
[Xperia Z1 General] Frewy:
What if I don't have an SD card? Can I just dump it on the phone?
[Xperia Z1 General] :
Yes. Internal memory works too :)
[Xperia Z1 General] Frewy:
Awesome :)

Final question (God I sure hope so), I goto the Cyanogenmod website and I can't find a download for the .zip file, instead I get a CMInstaller.msi. Where do I find the zip file for CM, for an Xperia Z1 C6903? I've tried looking but I can't find an download link, just news articles about CM and Xperia. -.- "Useless Web"
[Xperia Z1 General] :
Use this for CM10.2 (4.3) or this for CM11 (4.4)

CM11 hasn't receive any updates so I suggest CM10.2.
[Xperia Z1 General] Frewy:
I only see a download for Z1 for the model number C6902, mine is C6903. Will it still work?
[Xperia Z1 General] gregbradley:
[MENTION=5349287]BloodLust012[/MENTION] you have the patience if a saint [MENTION=5628247]Frewy[/MENTION] good luck, but it looks like you are trying to run before you can even crawl, but have a go and see what you can do yourself we will be here to pick up the pieces for you.

:)
[Xperia Z1 General] VyZard:
Can somebody help me ?
[Xperia Z1 General] Frewy:
Thank you both [MENTION=5349287]BloodLust012[/MENTION] and [MENTION=3843529]gregbradley[/MENTION] you've both been really good help :)
[Xperia Z1 General] :
Yes. It works for me. Mine is C6903.
[Xperia Z1 General] Frewy:
Awesome, and does the camera still work?
[Xperia Z1 General] :
Based on this quote, I say it's not
[Xperia Z1 General] gregbradley:
You said you have not rooted. You must root in order to get recovery working.

Put your phone on charge for a few hours then use flashtool to flash a stock FTF for your phone, or use PCCompanion to repair your software.
[Xperia Z1 General] Frewy:
****, I assume there isn't a work around for it then? :/ And I thought the 4.3 update fixed this problem anyway?
[Xperia Z1 General] VyZard:
Thanks!

Yes I have rooted, I needed to, first to back my TA partition, and to install recovery, it was working since I got to fnstall the rom from sd card, then I flashed the .290 ftf... I dont know what I did wrong.

But do you think your solution will still work? Cause pc doesnt seem to find it, flashtool either. Well I'll put it to charge and doNload pc companion, then get back to you. Thank you for your help!
[Xperia Z1 General] :
Camera fix is for stock 4.3 not CM 4.3 lol
[Xperia Z1 General] Frewy:
I'm at this step, how do I flash it exactly after putting the ROM zip file, gapps and the boot.img on the internal storage?
[Xperia Z1 General] :
Checking if we're on the same page. Did you download the Rom from here and Gapps from here? If yes then continue.

- First you need to get the Flashtool from here.

- Then after installing Flashtool, install the drivers from C:\Flashtool\drivers (Select Xperia Z1, fastboot and flashtool drivers)

- Now make sure you have the Rom on your SDCard. That is the CM.zip and Gapps.zip. boot.img will be needed on your PC.

(boot.img is in the CM.zip. Extract it from there)

- Open Flashtool.

- Turn off your phone. While holding the volume up button, connect your phone to your PC.

- Now press the 'Electric' button on flashtool.

- Select Fastboot mode and click Ok

- Select kernel to flash

- Then select the kernel boot.img (Note: Make sure to change the file extension from .sin to .img in the kernel chooser. It's above the open and Cancel Button)

- The flashtool will flash the kernel. (Move aside the fastboot toolbox window to see if it's successful)

If it's successful, reboot.

Once you see the FXP logo, repeatedly tap the volume up/down (not sure which, I usually press both) when there's either an LED Light or a quick vibration.

(Quick lesson: Volume up to go up, Volume down to go down, Power button to select)

- Once inside CWM, wipe data/factory reset. (Optional: go to mounts and storage and format /system) (Optional 2: go to advanced and wipe dalvik cache)

- Then head over to install zip, choose zip from sdcard OR external sdcard (depends on where you put both CM.zip and Gapps.zip)

- Flash CM.zip.

- Flash Gapps.zip after flashing CM.zip.

- Reboot and enjoy.

Any problems, don't be shy to ask.

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

As for you, the only thing I can suggest from my opinion is to unlock your bootloader. Since you've backed up your TA partition. After unlocking bootloader, flashing a kernel will be much easier and have less problems.
[Xperia Z1 General] Frewy:
Right, thanks I'll hang on to this information, I'm gonna wait it out until they sort out the camera functionality problem associated with installing CM, because I need my camera. When they release a CM update that fixes the camera, I'll refer back to this information. Thanks again :)
[Xperia Z1 General] :
No problem :) If you have anymore questions, feel free to ask. You can also try and search for answers.
[Xperia Z1 General] Frewy:
Just so you know, according to http://xdaforums.com/showthread.php?t=2461282&page=13 the new CM 10.2 has the camera working and showing an image, but it can't focus or take a photo. So hopefully in a few days there might be camera functionality on CM.
[Xperia Z1 General] :
Yep hopefully. The FXP team are reliable. Been using their Roms since Xperia Arc S. Then the Xperia V and now waiting for a stable release for Xperia Z1.
[Xperia Z1 General] TagEHeuer:
THANK YOU to both of you, I actually did more research and found it on the FlashTool website (will post link when I'm allowed)

Just to note, I didn't say in general it was impossible, but that I hadn't found a way so it was impossible for me. Sorry for any confusion. :good:
[Xperia Z1 General] VyZard:
Hey, so there's some progress, now the red light is blinking when I charge it, or connect it to the pc (blinking slower when on pc), I tried flashtools, it seems like it detects it, but tells me the usb debugging is off, so I dont know if I can use it. I downloaded PC companion, it detects it for a few seconds and then tell me it doesn't. So I don't know what I can do. I've put it to charge a bit more. I still cant boot it or get to recovery, I tried going into flashmode but doesn't work much. But the flashing light gives me hope. I had read about a recovery mode for pc companion but I don't remember how to get to it. So, do you have an idea/advice?
[Xperia Z1 General] :
I suggest you use Update Service. PC Companion don't work for me if phone is off.
[Xperia Z1 General] VyZard:
Hello! Thanks, yeah, trying it right now, tells me to push volume-down button but nothing happens
[Xperia Z1 General] :
While connecting?
[Xperia Z1 General] VyZard:
Yes, while connecting, like I did with flashtools.

I also waited for the light to go out before plugging it in again, but no luck.
[Xperia Z1 General] :
Ergh.... That sounds like a brick to me. I'm not sure. Never experienced a brick before. Have you tried reinstalling drivers?
[Xperia Z1 General] mpmaheshbabu:
Couldn't install 360 root

Supports only chineese OS
[Xperia Z1 General] VyZard:
That's what I'm afraid of... But this little light gives me a little hope, plus PC companion detects it a little so... What we need is big guns! haha (I'm still crying inside T_T) Thank you for your help anyway, I'll try posting in the rom thread and let you know. =)

SO 4.3 doen't support rooting yet? I just update mine. First time Android and Sony users here.
[Xperia Z1 General] laochek:
Hi I was on 534 rooted, OTA updated to 257 and preserved root. Now updated to 290 and lost root.Just wanted to ask if I unlock bootloader now do I restore my TA from the backedup TA on 257? When i relock just use Flashtool? I am still very caustious about unlocking bootlkoader. Thanks for any input
[Xperia Z1 General] gregbradley:
Yes, that TA backup is fine, however, once you restore the backup it relocks your boot and you will lose root.
[Xperia Z1 General] laochek:
Thanks for the info. By the way since imei is required in unlocking sony will know of my unlocking. Even I relock they will have a record? Coming from htc the bootloader is relocated and not unlock status leaving traces behind
[Xperia Z1 General] gregbradley:
They will have a record that you requested the unlock code, but they cannot prove you have unlocked after you restored your TA. You can argue that you requested the code but did not actually go through with the unlocking process
[Xperia Z1 General] jader13254:
About unroot... Just to make sure, is it also possible with PC Companion as it was back in the arc days? :D

Finally I got the courage to unlock bootloader. Flashed recovery and super Su and rooted. Stock kernel. I thought unlocking bootloader will lose the X reality engine? It is still present. So I tried Restoring TA but my phone cannot reboot!! In the end used flash tool to unlock the boot loader again. Otherwise I cannot boot phone. Very confused.
[Xperia Z1 General] Hate Android Lag:
tap build number 7 times in about phone
[Xperia Z1 General] :
Aa long as your bootloader is locked then it's fine.
[Xperia Z1 General] xasbo:
I am having an absolute **** time trying to root a C6906. I believe it's Canada sourced with BL unlock not allowed (:mad:). I received the phone and OTA updated to 290 before knowing about the complexities of rooting 4.3.

I flashed back to the generic C6906 257 found in [FTF] C6902 & C6903 & C6906 & C6943 FTF Mega Collection and both vRoot & Kingo still fail to root correctly. With each, I see the prompts for the MtkCamera install and the restore toast messages, but either the phone reboots a few times and or it just hangs out doing nothing. I'm trying to source a generic 534 FTF but not having much luck there (and I don't want to use the Rogers branded one). The bin4ry method is ineffective on 257 (hangs waiting for uevent_helper). 360root won't install on my laptop because I don't have a Chinese system and the APK doesn't seem to do anything before failing.

Can anyone point me in the right direction? This is my first Sony after using Samsung gear for years, so I'm a bit out of my element.
[Xperia Z1 General] jluiscc25:
hey i'm trying with both systems and in one nothing happends (vroot), and the second (360) tells me that only spports chinese OS, and don't will open, what can i do?
[Xperia Z1 General] RushNReady:
has any one tried this way of rooting before with success http://www.oneclickroot.com/phone/sony-xperia-z1/
[Xperia Z1 General] jluiscc25:
well i just download it, and starting the installation when the program just abort the download
[Xperia Z1 General] shem2409:
You need to downgrade to .534 to root.
[Xperia Z1 General] RushNReady:
what you mean ?
[Xperia Z1 General] shem2409:
Xasbo tried to root with vroot on. 257 firmware. You need to be on. 534 for the software to work.
[Xperia Z1 General] RushNReady:
sorry shem i meant this comment
[Xperia Z1 General] jluiscc25:
well, the problem is not the phone, the problem is that the program ask for download information (phoen has not been connected) and pop up the message of "download failed"
[Xperia Z1 General] xasbo:
Thanks - any idea where I can find a generic? I found a Rogers 534, but don't want the branding. I don't know of a way to use my generic 257 to keep root, is that even possible?
[Xperia Z1 General] shem2409:
It's a tough one as there isn't one in the ftf thread. Maybe check out the branded one, with root you could always remove all the bloatware anyways.
[Xperia Z1 General] xasbo:
I had no problems running the PC software, but it was not able to root a C6906 on 257 (which may be a separate issue entirely). Keep in mind that like all closed source solutions, you should be wary of the true nature of the application. I sandboxed the app on my PC, but it didn't set off my AV software nor did I find anything particularly malicious related to the site on google.
[Xperia Z1 General] RushNReady:
Thanks for checking it out. In just really nervous about rooting. Don't know what to do and if it really worth the risk
[Xperia Z1 General] mitchy1690:
I just tried it and it failed
[Xperia Z1 General] xasbo:
When in doubt, hold off. Either something stable will be figured out aand documented, or we're all SOL. I've been trying to get root to use TiBu, but that's not a huge inconvenience. I can't BL unlock for the moment, so I don't have as much to look forward to anyway.
[Xperia Z1 General] suleiman.aql:
Tried it and it didn't work.
[Xperia Z1 General] amm009uk:
Can't answers all your questions but..

root doesn't cause any side effects and it's only availible to apps you allow. I'm running no Sony apps as I don't need them. I removed a whole bunch of stuff from the ROM before flashing. Still on RomAur 3.1 runs fab all round. I can't really compare against stock as I flashed right after I got the phone. RAM has never been a concern for me may cause I don't play games or such on the phone.
[Xperia Z1 General] darkwaste:
Excellent!

Thanks for all the useful information!!
[Xperia Z1 General] tdthd:
I have cast a backup of the partition ta, with the .534 version and a locked bootloader. Yoigo is purchased from Spain.

I will release and send it to sony, so let me unlock the bootloader.

I wonder if when sony send me with open bootloader permission, if the backup of the partition ta, would serve or have to redo it again and if so, to which version of the rom would have to. Because the .290, to make root, unlock the bootloader and would lose the partition ta.

forgive my bad English.
[Xperia Z1 General] xasbo:
This is a good question for Sony, you're the first person I've heard of going through this process. Since unlocking the bootloader normally clears the TA partition, do not lose your current backup. Make sure to also back up the rest of your data (the SD card may be wiped as well).

Who did you contact at Sony to arrange this unlocking service? I have a C6906 in the US and would like to unlock my bootloader.
[Xperia Z1 General] tdthd:
sony second, I have to unlock network z1, be able to use any sim.

then I have to send an email, you sending them my ime and unlock code network.

they send me an e-mail response, saying that if the unlock code is correct, I sent a parcel agency, to collect z1, along with the invoice to confirm that is purchased and not stolen.

but I have the doubt that if the backup partition that I have ta, will serve after that.
[Xperia Z1 General] Hate Android Lag:
ok, so i decided to root my z1, download greenify, undercloak cpu, tweak governor, remove bloatwares & flash a better equalizer. but i can't decide whether i should flash a custom rom & kernel, is the stock rom & kernel good? but the thing is im afraid that if i root, i wont be able to update system & apps OTA. OTA is important to me cuz the pc companion gives lots of problems. the OTA updates are cool cuz it updates my walkman, camera, album & other updates might roll out in future. after rooting, is OTA possible?
[Xperia Z1 General] whoosename:
I'm on .290 generic central europe, rooted and unlocked BL. Update Sony apps like Walkman, Albums etc via OTA without problems. Other apps update (play store) without probs too.

Because of unlocked BL, I think ugrade to 4.4 KitKat via OTA will fail. I'll see soon
[Xperia Z1 General] Hate Android Lag:
guess i'll have to wait until kitkat is out. but i dont think its soon cuz 4.3 is out days ago on OTA. what u think bout the stock kernel n rom? need a custom one?
[Xperia Z1 General] whoosename:
It's been said that KitKat will come in january 2014, so I'm optimistic that Sony will release up to the end of month:laugh:

I'm pleased with stock rom for now, maybe a custom one when KitKat is out. For to unlock BL I neded to install a custom kernel with a recovery.

I've choosen lzyllp's CWM Recovery from here: http://xdaforums.com/showthread.php?p=48576380
[Xperia Z1 General] Hate Android Lag:
gosh its probably just awesome if they skip 4.3 as 4.4 work on lower budget devices. anyway, who wants 4.3 when there's 4.4? anyway now i realise sony has this promotion um, buy a z1 on christmas till 1 january 2014 & u'll get a free gift. is this international? cuz im not getting the gifts from the shop on the christmas when i bought the z1. did the shop cheated me? i got this red xmas package instead of the normal one. i have contacted sony mobile on fb, but thy havent respond yet, probably busy.

You are probably on .257 firmware version. You will need to downgrade to .534 first before you can root.

[Xperia Z1 General] XSilentCobraX:
I tried reading up on this, but didn't find an answer, if i root xperia z1 i can still update it via either pc or OTA? i only want to root so i can install xposed framework:)
[Xperia Z1 General] xasbo:
Only up to .257. If you upgrade to 290, you will lose root because it's Android 4.3 and you will be unable to re-root unless you have an unlocked BL (and only partial root at that). On 4.3, full root is possible with unlocked BL and partial root is possible with locked BL. Xposed will work with partial root.
[Xperia Z1 General] XSilentCobraX:
Im already on android 4.3:) so i might face problems when 4.4 kitkat is available?
[Xperia Z1 General] xasbo:
Presumably, yes. We won't know until it's here.
[Xperia Z1 General] XSilentCobraX:
is this the only way to root? im facing problems with Vroot, nothing happens after i clicked root, and 360root wont install on my desktop due to it not being chinese :S
[Xperia Z1 General] xasbo:
You didn't read what I or a lot of other people have been saying, in this very thread. Your problems are not new.

* Only 534 can be rooted.

* After rooting, you can only OTA up to 257. Root is lost when upgrading to 290.

* 290 can only be partially rooted if you have a locked BL. Full root is possible with unlocked BL.
[Xperia Z1 General] XSilentCobraX:
I did read through this tread, but apperently i missed these, but thanks for helping out, i guess ill just wait until another solution comes up:)
[Xperia Z1 General] shem2409:
This last statement is wrong.

*.290 can be fully rooted only on unlocked bootloader. You can however have a partial root on locked bootloader with no system write permission, Xposed Framework will work on partial root as well.
[Xperia Z1 General] xasbo:
Thanks for the correction. I edited my posts.

[Xperia Z1 General] shem2409:
If you have unlocked the bootloader, all you need to do is flash a custom kernel to regain root.

Do you think that if i restore to factory i would come back to 534?
[Xperia Z1 General] shem2409:
Most likely never, because there is no point for developers to waste time on finding another root exploit if this method works just fine.
[Xperia Z1 General] klankpulse:
Okay, I have read through the lion's share of posts in this thread, but I am unable to root my phone. I will list all of my specifics below, in the hopes that one of you might be able to help me!

Computer OS: Windows 7

Root Software: Kingo

Phone: XPERIA Z1

Android version: 4.2.2

Build Number: 14.1.G.1.534

Developer mode enabled

USB debugging enabled

I can connect to the computer, but when I try to root my phone with kingo, it does not detect that USB debugging is turned on. I have re-isntalled kingo, and rebooted my phone, as well as switching USB ports.

If anyone could help me, that would be fantastic!
[Xperia Z1 General] jluiscc25:
Try to re-install the drivers, work for me, when i was on 534
[Xperia Z1 General] klankpulse:
Which drivers, and how would I go about doing that? Thanks for the quick reply by the way!
[Xperia Z1 General] jluiscc25:
on the sony web, google sony z1 drivers, and you'll find the way home :D
[Xperia Z1 General] xasbo:
Grab a generic 534 FTF for your region and use flashtool to downgrade. Then you can root and update to 257. However, root will be lost if you decide to update to 290 and you'll have to go through a separate rooting procedure, which I linked above.

However, full root is possible on 290 if you can unlock your BL, partial root if you cannot. It depends on your goals whether 534 root is worth it.

Are you using the OEM USB cable? Believe it or not, this can make a difference. Unfortunately, I don't recall what I did for drivers, so I can't help you there, but googling Xperia Z1 drivers will almost certainly find your answer.
[Xperia Z1 General] jluiscc25:
well, right now "Telcel" release the 257, i think they will release the 290 in a day or 2, may be till monday, and if i can root the 290 well, i'll wait, thanks for the replay ;D
[Xperia Z1 General] klankpulse:
Will the drivers change my phone's firmware from .534 to a newer, unrootable version, or should I be fine?
[Xperia Z1 General] xasbo:
The drivers you install on your computer have absolutely nothing to do with the firmware on the phone.
