Which country are you from?

No need to do any of that if your boot loader is unlocked. Just flash a custom kernel.

For downgrading firmware version? That's not really a good choice, flashing with a tft file is clearly better, flashing a custom kernel can hard brick your phone, avoid your warranty and can't be restored with SUS and PCC...

No, he asked how to root. If he has already unlocked the bootloader then the simplest way to root is flash a custom kernel. Warranty is already broken and what is the point in unlocking the bootloader unless you are going to flash a custom kernel anyway

Yeah but flashing a custom kernel is not necessary for having root on the latest firmware.

No its not, but its the easiest way to get root if you have already unlocked.
And please tell me the point of unlocking if you are not going to flash a custom kernel.
Its harmless as long as you flash the correct kernel. It carries the same risk as flashing anything.

You have downgraded in order to root then to do an OTA upgrade back to .257 if I am right.
In which case, do not worry that the camera does not work in .534, just root it, and upgrade OTA.
Then try the camera.
EDIT
Also you need to clear the data in all camera related apps

my questions on the z1

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
so i got the c6903 now... i cant root it and i dunno why
its running on 4.2.2 .257 fw official
i tried vroot it didnt work and 360 root cant be installed it says chinese only os.. how to do that now?

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

bsmstar said:

Click to expand...
Click to collapse
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...

Look at the root. 266 thread for unlocked bootloader..
It's exactly the same, the only difference is u have to flash the. 201 kernel again after finish rooting to experience improvements in the update..

Just a few questions please help. To keep our phone's warranty, we need to back up first the TA partition before unlocking right? I read and watched tutorials on how to back up but it needs a rooted phone so i search again on how to root, but unfortunately it requires unlock bootloader. Am i right guys?

Problem rooting Xperia Z1 (KitKat)

Okay .. So I'm running ver. 14.3.A.0.681 on my Z1 and I want to root it .. I heard of a method in which the phone must be downgraded, then rooted, then reupdated again using flashtool .. But every time I try to downgrade I get stuck in a boot loop .. I have managed to fix the boot loop problem by reflashing the 14.3.A.0.681.ftf
Please guys how can I downgrade without having this problem? And does this rooting method work? If not, what should I do?

Hi ralph97,
Here is what I did (although I was on .257 to start with)
1) Flashed C6903 14.1.G.1.534 Generic from here - http://forum.xda-developers.com/showthread.php?t=2469191
2) Install dualrecovery from here - http://forum.xda-developers.com/showthread.php?t=2261606
3) Flash SuperSU (via recovery) from here - http://download.chainfire.eu/282/SuperSU/
4) Update to NUTs .681 from here - http://forum.xda-developers.com/showthread.php?t=2687443
Each time I flashed an ftf, I cleared everything, so I made a backup (I just copied the stuff such as music, photos etc to my pc)
I hope that this helps.
PS - all cradits to helping me to @gregbradley

If you open the BL there is no need to make all the way back to 534.
You just have to open the BL install a recovery, on the 680 ftf, and then install the supersu.

Yes this is true, but you may want to backup your TA partition before unlocking the bootloader and this needs root, so you have to downgrade to .534 anyway.
So, yes technically you can do this, but I DO NOT advise it.

Well, the first time you do it, probably it shoud be done as you say. :laugh:

i also do that...its work..dont need to downgrade..

You need root to do it, so it has to be done BEFORE you unlock.

Please remind to People the consequences in doing this! Like the Warranty, after Unlock Bootloader, will be Voided and even before that, like @gregbradley already said, Backup TA to not lose DRM Keys. The short way isn't the best all the time.

You do not reupdate by flashtool.
Only with the recovery.

You still need to flash SuperSU to get full root, but in step 4 just flash the ROM of your choice.
