Hi guys, I'm getting a z1 tomorrow
Should I get c6902 or c6903 ? I don't need 4g but I want a device that has many mods/ ROMs. That's all I need.. Second, what is lb and UB ROM? Third I want to install ROM on new device, the steps of installing ROM is something I don't understand.. My experience with grouper nexus 7, unlocked it, flashed it.. But z1, how to do that? Can someone explain basics to me?

- depends. Is your device that you've ordered support LTE? If yes, then you'll get C6903
- LB = Locked boot loader. A state where you can't flash custom kernel
- UB = Unlocked boot loader. A state where you've unlock your boot loader, so you can flash custom kernel.
- which steps?
- there's ROM which can be flashed even your bootloader still locked. So, it depends on what ROM you wanna use.

OK thanks for replying , so let's see.. How can I flash monxdified on a completely new device? I think the device is c9602 since I don't see a 4g on the package..
What is the best custom for this device? What's new on Sony kitkat ? Can we have it for Christmas eve?

1. Backup your TA partition (just in case you want to roll back to 4.2.2, and get back your DRM key)
2. Check for updates using OTA or Sony PC Companion
3. If there's update to 4.3, apply the updates
4. Before we step further, I wanna ask you, do you wanna keep your bootloader unlocked?
Well. We don't know when exactly 4.4 update is available. Let's hope we'll get this in December.
Hi
For me it doesn't matter if BL locked or not, I read there is no problem in that in 4.3 regarding camera issues.. But I have zero knowledge on how to deal with rooting and flashing the z1.. Im not going back to 4.2 for me its either aosp 4.4 or Sony ui 4.3. As I said I have zero knowledge so if you can elaborate more about how to do it that would be highly appreciated
hi

There is no better way than follow this steps on Page 2, Post #16 http://forum.xda-developers.com/showthread.php?t=2588331&page=2
No body here was clever at the first time so just read carefully. This is the only way to get the full root on your device.
If this help click on thanks.
Well, I found that out through YouTube.. I downgraded my c6903 to 534 fw and rooted it, installed the recovery dual and flashed ihackers 2.1 , yes I did ta backup but I didn't unlock the bootloader. I dunno what's the benefit of doing so, although I emailed Sony and I got the unlock code on my email as they replied... I'm only missing an app that control the led color of notifications led and Google now since I'm not in the US region.. That used to work fine on 4.2.2 but no worries.. Thanks guys. You really helped me a lot and I think this is a great device, I have been using it since Tuesday. And I rooted and flashed it this morning. One problem is that I dunno how to enter recovery so I flashed the ROM right after I flashed the recovery.. I understand now that there is a flashable zip? Things are much easier with the nexus line

All the FTF have to be flashed on your device via Flashtool v0.9.13 compatible with your device and they are not zip. Recovery is in zip and all what you flash from recovery is in zip file.
Yeah I did that.. It had 257 fw, I flashed 534 with flashtool then I rooted by vroot, then ta backup with some bat file through computer and USB debugging, then installed recovery by bat file as well, which rebooted to recovery, I did factory reset/wipe, and flashed aroma ihackers 2.1 without custom kernel then switched off and flashed baseband and kernel by flashtool and rebooted, done..
Just like that. And you should be the one without knowledge?
Well, I put my mind to it.. And when I do that I usually succeed... But I still have unanswered questions, like what are the benefits of unlocking bootloader? How can I control led light color for different applications notifications.. I tried light flow and illumination bar, both didn't work.. Lastly I haven't got used to the camera ui as I haven't used it much and I already applied xposed 20 mp mod.. Lastly,, I like to thank you for all your attention and care and everything ... I really appreciated it
as i know the unlockbootloader is the only way to flash custom karnels.
i dont know mutch more then that, just switched from ios so i'm new to this.
I forgot to backup my TA does that make an issue and if, what kind?

Yes, it's a problem, without TA you lost your DRM keys permanently which are needed to re-lock your bootlader. You also lost the warranty of you device definitely.
yea i know the waranty and drm
but what does the drm keys do i lose some functions?

Yes, Bionz, X-Reality and probably Bravia Engine or something like that but your phone still working properly. Some users do not notice the difference with or without this features.
Ok I tried gravity box, can't find notifications led settings... Can you be more specific on this? Thanks...

Hello,
Coming from a Galaxy S2 flashing and rooting is not new to me but for me there are some questions for the Xperia Z1.
When i bought the Z1 it was on 4.2.2, and offcourse i wanted root the same day
After trying numerous times with Vroot i gave up.
After some more reading i read that i had to downgrade and then flash an older version, then root and flash teh correct version and so on.....(cant find the correct topics anymore )
After doing that my phone wasnt working properly and i connected with PC Companion and it gave me the update to .290 JB 4.3 and everything was fine except foor root.
Did some more reading and found the solution,
Now I'm reading that if you are on .290 4.3JB that root isnt possible(correct me if im wrong).
I want to share how i did it because for me it went very easy.The hardest part was getting the drivers installed correctly hhaha
First i unlocked the bootloader and then i flashed a CWM with root and recovery.
I followed the steps provided on this links.
http://techbeasts.com/2013/12/18/how-to-unlock-bootloader-of-sony-xperia-devices-guide/
http://techbeasts.com/2013/12/19/in...ng-latest-14-2-0-a-290-firmware-how-to-guide/
Al of this went so easy that i'm startin to wonder if its me who did it wrong and dont understand it or if you didnt know about it,
The only thing i forgot was a TA backup :angel:
to MODS....if its in the wrong section please replace it.
Actually it is the official way. Unlock -> CWM -> Root with CWM (Notification)
Rooting 4.3 isn't impossible, but morr difficult than on earlier versions. Google wanted to improve the security of android. Most of the ways which "make" the opportunity of rooting are malware-ways too.
You don't need to backup your TA partition with .290 and above, because the camera will work after the BL unlock.
The big question is if root for unlocked boot loaders will ever be available for 4.3! I really doubt it.
Sent from my C6903 using xda app-developers app
You mean Locked Bootloader, i think?
Question about CWM, does it function the same as it did with my S2? So, back-up and restore with CWM?

I have heard from @shem2409 that a partial root on LB for 290 (4.3) is possible, but I have not figured out how to do it yet. I think you can pull it off with the insecure ramdisk hack, but to install that, you need to install XZDualRecovery; to install XZDR, you need to be rooted; it's only possible to root 534 LB and when upgrading to 290 root is lost. So, it seems to be a chicken-and-egg problem to me at the moment. I think I must be missing something.

That's why I do not rooted mine phone yet. Partial root is not worth to do, full root is what we really need but still under testing and also Unlocked Bootloader is needed. Unlock bootloader we lose the DRM keys which we need if one day we want go back to stock and not lose warranty but to do that we have to Buckup TA. To Backup TA we need root, but I updated to 4.3 and I can't. It's to early to fully rooting 4.3. We have to wait. Developers are working on that and I hope a full root come without unlock bootloader. I hope so.

If you want to backup TA now, you can - flash back to any 534 FTF, root, make your backup, then upgrade back to 290.

This is what I don't want to do. Unlocking Bootloader on 4.3 will also compromise few features like Bionz and X-Reality. I don't think I really need them but for me will be good enough to have Full Root with Locked Bootlader and Apps to SD. I don't ask to much, so I wait.

You just took those words from my fingers. The wise way here is waiting and cheering developers to figure out how things work with Z1, 4.3 just came a few weeks ago and (hopefully) we will get 4.4 soon, so for that time you'll have to do that trickery again to keep your phones rooted.

I mistakenly took the .290 update as well and I'm now looking for a way out. This whole backing up the TA thing worries me because I'm afraid I'll lose those DRM keys and bravia etc..... Are you saying that I will be fine and all the keys will be intact if I follow this guide?
Is it possible to downgrade the firmware instead?
What would you suggest?
Thanks

Ok, so here is a little clarification
You need to downgrade to .534, root, install recovery and then flash a prerooted .290 rom from (http://forum.xda-developers.com/showthread.php?t=2572988) or one of the stock-based custom roms such as monxdified (http://forum.xda-developers.com/showthread.php?t=2463675) if you want a partially rooted, locked bootloader 4.3 firmware on your Z1. There is an instruction on how to install on locked bootloader in the thread.
Rooting on the newest version of Android 4.3.3 isn't impossible on the Xperia Z1, it just takes you more steps than normal to actually get full root access. I have a locked bootloader as well but I was able to get a rooted version of Android 4.3.3, specifically the iHackers 2.0 ROM running Android 4.3.3 with full root access. Here's how I got full root access on the iHackers 2.0 ROM:
1) Download the .ftf file named C6903 14.1.G.1.534 Global 1277-2880_R4A from the compiled FTF thread at this link: http://forum.xda-developers.com/showthread.php?t=2469191
This is a version of the original Stock Rom that the VROOT program will actually work on when trying to ROOT your phone.
2) Flash the ROM you downloaded using Flashtool (steps on how you can go about doing that should be in the Xperia Z1 General forum.) and now, you're ready to root your phone with it.
3) Download, install and run VROOT to root your phone. Again, more information on how to properly root your phone using VROOT can be found in the Xperia Z1 General forum. For me, I just turned on USB Debugging on my Z1, connected my phone to my computer while VROOT was running and clicked the green button until I got root access. It's extremely easy.
4) With Root Access, now you can download and install Dual Recovery for the Xperia Z1 on your phone.
5) Download the latest iHackers 2.0 ROM from the Xperia Z1 Android Development thread and copy it to your phone. This is hands down, the best ROM for the Xperia Z1 right now in terms of battery life. With the latest 4.3 update, I'm able to get over 2 Days worth of battery life on one charge. Battery life is much better on the new iHackers 2.0 ROM running Android 4.3.
6) Download the flashable Locked Dual Recovery for the Xperia Z1 here. http://nut.xperia-files.com/
The file is called XZ-lockeddualrecovery2.7.63-BETA.flashable.zip (8.48MB), download it and copy it to your phone, preferably the same place you copied the iHackers 2.0 ROM. To make things easier for yourself, create a new folder on your phone or SD Card in your phone and name it iHackers. Copy both the iHackers 2.0 ROM and the flashable Locked Dual Recovery.zip file into this folder.
7) With both files now copied to a folder on your phone, you're now ready to go into recovery to flash the iHackers 2.0 ROM. Boot into recovery and once you're there, do a Wipe Data/Factory Reset before Installing the ROM.
The rest of these steps are now taken directly from the iHackers 2.0 download thread on the Xperia Z1 Android Development forum.
8) Install the ROM and THEN Dual Recovery. Don't make the same mistake I did, once the installer is finished, DON'T REBOOT THE DEVICE. Uncheck the "Reboot Device" box and go back to recovery to install the flashable Dual Recovery.zip file that's in the iHackers 2.0 folder.
9) Switch Off Your Phone (Do Not Reboot). Select No to Disable Flash Recovery Confirmation.
10) Install Kernel.ftf for C6903 (.290) or Kernel.ftf for C6902 (.290) with Flashtool to get compatible Kernel and Baseband. To download the kernel.ftf file, go to the original iHackers 2.0 thread to download and flash the kernel using Flashtool. You should be familiar with Flashtool at this point since if you make it to this step, you've already used Flashtool once to flash the .534 baseband version of Android.
11) Reboot and Enjoy. Now you're running the latest version of Android 4.3 on your Xperia Z1 on a Locked Bootloader WITH full Root Access. Sure, it's not the stock version but the iHackers 2.0 version of Android 4.3 is just as good, if not better. This will certainly do until there's a better way to simply root the newest Stock Version of Android 4.3.
I've been looking into unlocking my bootloader to install custom kernels on my Z1 but the battery life and performance on my Z1 with a locked bootloader is already pretty impressive. I can't imagine how good it could be with a custom kernel.

No, if you Unlock Bootloader you will lost the DRM keys permanently with Bionz and X-Reality, even with Android 4.3, if you do not do a backup, but the difference from 4.2 is that your phone will still working properly.

Thanx man. I appreciate the time you took to explain the process step by step. One step very important you forgot to mention, Backup TA, never forget to mention that.

The instructions didn't say to unlock the bootloader, which is the only sure-fire way to lose your TA partition. However, I would agree there's no good reason *not* to back it up anyway. Better safe than sorry!

Sorry, no. In his instructions, UB is not necessary because XZDualRecovery can be installed on LB. The reason skipping the TA backup is okay is because the instructions do not unlock the BL.
Hi guys this is my first post here so be gentle! I'm trying to get cyanogen mod on my Z1.
I have followed the guides on this forum, my appreciation to all involved here great job!
I downgraded to 4.2.2 from 4.3. I then rooted my the phone. I then unlocked the bootloader.
All went ok. I then downloaded C6903_14.2.A.0.290_1276-0875_Generic UK.ftf and flashed it. The phone then wouldn't turn back on.
So I downloaded C6903 14.1.G.1.534 EE UK 1276-2219_R9A (I'm on EE) and flashed that and I got the phone working again.
I then flashed DoomKernal to get CWM. DoomKernal went fine.
Somewhere along the line I think I got confused and thought DoomKernal would give me CWM and I flashed C6903_14.2.A.0.290_1276-0875_Generic UK.ftf again to upgrade back to 4.3.
Same problem...Phone wouldn't turn on so I repeated the EE branded 4.2.2 flash.
Now DoomKernal seems to be taken off. So my questions are as followed:
Do i need DoomKernal to get CWM?
Do i need to be on 4.4 before I install Cyanogen mod or can I do it straight from 4.2.2 with DoomKernal?
If I'm being a total noob I apologize!
Thanks.

Accidently gave you a thank lol
I actually don't know about branded phone, but I can tell you that your step has gone wrong. You will always lose root
if you flash a sock ftf file.
So you are saying you unlocked bootloader on the 534 rom? Your camera is probably dead now, check it if you can boot.
Unlocking bootloader before getting on 4.3 or 4.4 will result in disabling the camera. You did it now anyway, I can't help you. Maybe flash 4.4 now and see if your camera works again.
Flashing cyanogen is not about root but unlock bootloader, people would recommend you to root first becoz you will be able to do TA back up with root
(TA backup is a way to backup drm key, so you can restore it in the future and restore locked bootloader exclusive feature like X reality and better quality camera. Seems you don't know what I'm talking about and already unlocked the bootloader before you even ever heard about TA. Sorry can't help you to save this part, you may continue anyway)
So on 4.4, you may have to unlock the bootloader again since the bootloader itself maybe relocked itself when you flash a sock ftf file. ( doesn't mean you restored DRM key is back)
So maybe unlock it again and start to flash cm.
Personally I wouldnt recommend a newbie in Android to unlock bl so fast since it's too easy to mess up serious things up and it's not so easy for turning back. Well you started messing them up anyway, continue then
Thanks for the reply.
I did do a TA back up before I unlocked the bootloader....If i restore from this will it get the camera working?
I have tried to flash Cyanogen mod but it fails error 7. It thinks my Z1 is a Togari (Z ultra) which it isnt cant find anything on this!
Ok so, i'll try and get on 4.4...
I have a UK Z1 C6903.
Can I flash to C6903 14.3.A.0.681 Global 1277-2880_R5C (this is 4.4 right?)
OR does it have to be a UK one I cant seem to find a uk 4.4?
So after a bit of stress and the phone getting stuck in bootloop I have installed 4.4.2 using .681 commercial.
I hope it will be smooth sailing now to install cyanogen mod
Oh and the camera works again!

until now I used several roms, like iHackers, CM, PA, slimkat etc and never lost root; today I updated to the newest stock rom, via sony emma, to see all the changes they've made and lost my root access.
is there any chance to get root again without the downgrading process again? I only did it once and this is a long time ago. I am not a highly advanced user but always curios to learn new things.
I really appreciate your help.
data:
lollipop 5.0.2
build: 14.5.A.0.270
xperia z1 c6903
germany
additional question: is xposed already working on lollipop? only had JB and KK so far

If your bootloader is unlocked, it's possible for you to root without going back to Kitkat. Just go to Xperia Z1 Android Development, and look for 270 kernel...
If it isn't unlocked, you have to go back to Kitkat and use any pre-rooted 270 ROM.
By the way, you posted in the wrong place.. You should post in Xperia Z1 Q&A, Help & Troubleshooting :laugh:
Good luck!

Sorry for posting in the wrong place.
Bootloader is unlocked with newest TA update. I will look for the kernel, thank you for replying.
As you unlocked your bootloader, you can gain root using two different methods:
You can search for an autoroot kernel for the 14.5.A.0.270 firmware as said above
or if you would like to not mess around, you can also just boot any kernel with recovery without flashing it using
Code:
fastboot boot boot.img
and then sideload the latest superSU zip via adb using
Code:
adb sideload sideload.zip
You can grab the latest superSU zip here
That's the way I personally like the best, as it keeps the stock kernel
Xposed works in parts as far as I know. The installation is still a quite experimental procedure and not all modules may work properly.

Hello folks!
I know my question has been repeated thousand times here.
I have tried to understand by myself and read as many threads as i can but to save some time and data bandwidth i want to know the shotest and safest procedure to downgrade my z1 c6902 from lollipop 14.5.A.0.270 locked bootloader to kitkat and try some custom kk roms. I have already rooted lolllipop using kingroot app. Recovery is not installed yet.
Do i have to flash kk ftf before doing anything?
Or i can directly flash dualrecovery and start flashing cm roms?
Also want to confirm wheter i have unlocked my bootloader to use cm based kk roms?

since ur already rooted ur lolli better to run the executable NUT's dual recovery and then back up the system to ur external.
answer to 1st question, yes u have to flash KK ftf if u want to downgrade.
u can flash directly the nut's dual recovery and flash custom rom like rockz1 and dstrikers rom
3rd bootloader is required to unlock if and only if u wanted a modified kernel like trinity..it depends on custom rom's requirement..better read it
