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

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?
sorry for thread steeling

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...

[Q] Confusion on TA Partition backup with the latest stock firmware

Hello!
I have searched various places about rooting my SP. I am about to root my SP, it was newly bought (2 months old) so it would be better if the TA Partition is backed up. After inspecting several articles and stuffs, I was advised to back up my TA Partition before attempting to root my phone.
As of 12.1.A.0.266 update, rooting requires unlocking the bootloader. Which doesn't follow the rule to back up the TA Partition. As one may know, a phone must be rooted in order to back up the TA partition but at the same time, such bootloader must not be unlocked
I've searched everywhere I can, however I can't find any solution. Forgive me if there are any articles or thread created regarding the same topic.
Any immediate help would be extremely appreciated.
The phone is running latest stock firmware and had no customisations so far.

Use a pre-rooted rom (PureXSP, eXistenZ)...Not sure if it will work!Don't try unless a person with higher android knowledge skills answers!

How about you just FTF flash an older firmware?

flashing ftf won't require unlocked bootloader isn't it? I do thought of downgrading then root and then backup such TA partition.

No it wont.
For the Sony features like Bravia Engine etc you need the TA partition. Flashtool will (or should) work without the TA partition. It will only tell you that your bootloader is unlocked

I was in the exactly the same position as you few days ago when I decided to customize my Xperia SP
Here is what I have done...
I was on the latest .266 OTA updated FW and then ... ...
I downloaded and flashed with Flashtool "Xperia SP (C5303)_12.0.A.2.254_Generic_DE.with_loader.sin.ftf"
Then flash XperiaSP_C530X_12.0.A.1.257_KernelOnly.ftf
Now you can use DooMLoRD_Easy-Rooting-Toolkit_v18_perf-event-exploit.zip
and then flash back XperiaSP_C530X_12.0.A.2.254_KernelOnly.ftf for your current FW
Now that you have rooted your phone you can use Backup-TA-9.10 tool to backup your TA partition and save your precious DRM keys
And when you have your TA partition backup safely archived somewhere
you can go to Sony site to request code for unlocking bootloader.
When your bootloader is unlocked use FASTBOOT to flash any kernel that have custom recovery
(like Nayak03 or DoomLord's V05 or DoomLord's advanced STD .266)
and then when you have custom recovery you can install pretty much everything you find around here.
If you need more details or want me to put links to threads and files I've looked and download just say... :cyclops:

It is not about Flashing, it is warranty.. My phone is 2 months old and there are 8 more months for valid warranty.

Wohoo thanks! Yes, I do thought of the same way, however, I am looking forward to use the stock sony .266 FW after rooting the older 254. Any tutorial you can give here or any links I can get on how to actually "install" the .266 firmware?
Yes I do would like some links on downloading those stuff except Flashtool, I did have it already. If you don't mind posting them..
By the way, since I see that .266 FWs have different versions for each region on this world respectively, may I know how to get one that is international or south-east asia specific?

Hi there guys!
I want to root my Z1 c6906, unlock the bootloader and flash custom roms, but im kind of confused right now because i have read a lot of different guides and im not pretty sure which one to follow now. I also learned on one thread that i should do a TA and DRM Keys backup because they can be lost forever if i don't do a backup. Also the IMEI. So im not pretty sure how to do that. Also saw a thread about bricking the device, and kind of got scared. Btw, i have plenty of experience working on Android devices, unlocking, rooting, flashing roms, etc. I have used Android since the G1, but im kind of confused right now about how to proceed on this device because this is my first Sony and my last phone was a Nexus 4, which was virtually unbrickable. Can anyone help me out here?

Quite simple process actually, just flash .534 ftf with flashtool and root with bin4ry or use nuts dual recovery installer. To backup your ta before unlocking bootloader, simply use the Backup TA tool

Sorry for bringing back this thread. Now i got time to start trying to unlock the phone and flash custom roms, was extremely busy before with work.
New problem: After i downgraded to FTF .534, rooted and made the TA Backup, i check if the phone was "allowed" to be unlocked and surprise, it says it can't be unlocked. Tried unlocking with Flashtool and it said the same thing. Can the phone be unlocked or is there a way to flash roms without unlocking?
Right now im feeling really depressed with this phone. If i can't unlock it, i most likely will sell it and get something that can be unlocked.
One of the reasons i want to unlock is because on 4.4, Google prohibited the phone to write on the Ext.SD and i want a way to overcome that prohibition and use it like i was able to on 4.3.

If it says it cannot be unlocked then it cannot be unlocked
However, you can still sort out the issue of writing to the ext SDcard by rooting and following the instructions in this thread
http://forum.xda-developers.com/showthread.php?t=2687966
In order to do that, you only need root, not to be unlocked

Another question: How i root.757? I was able to root .534, but not sure how i need to proceed now. Do i need to download generic .757 and apply any root method? Or the root will still be there if i flash it over my current rooted .534?

1) Flash a stock 534 FTF (Ignore if you are already on 534)
2) Install dual recovery (Find files and instructions in the XZ dual recovery thread in the cross device development section)
3) Flash a prerooted 757 rom (Find files and instructions in the development section)
Done, 3 easy steps

If your bootloader is unlocked you can flash any rom from the development sections or the original development section
But if your bootloader is unlocked you do not need to do any of this to root.
Just flash DooMKerneL or [NUT]s XZDR kernel
If your bootloader is locked, you have to downgrade and root that way. Then you can flash any stock based rom, look in the development section for them

Oops. Im sorry. I meant locked. Was doing something else and wrote that fast. Thanks for the answer. Will check. Got the DualRecovery installed now and will try to install a prerooted .757 later.

[Q]Just to be sure about rooting.

To get my device on a 4.4 rom with root i need to take the following steps:
- Downgrade to .534 with flashtool (I got [nut]version)
- Install latest Dual Recovery (z1 beta .123)
- Flash Prerooted firmware through recovery (Monx for example)
- Flash Stripped Kernel with flashtool (Nut .757 for example)
No need to backup TA then?
It look so simple, but it seems very complicated to me on the other hand.
Thanks for answering.

I'm not going to unlock the bootloader, thats why i asked about the TA backup. If i'm doing that in a few months, i can still do that then right?
And can i put the flashable firmware onto the sd card before downgrading? Or will the sd card be wiped?

Hi everyone,
I bought this phone these days.
I've update it to Build no. 32.1.A.1.185, Android 6.0
There is a method to root this version of firmware? I need only root, for now no recovery or xposed..
Someone can help me?

use this http://forum.xda-developers.com/xperia-z4/development/rootable-kernel-sxz3-ivy-marshsmellow-t3336607
it works with 32.1.A.1.185 version,
dont forget to flash drmrestore to have xreality, bionz etc back

Thank you very much for fast response.
But, a method like "kingroot" on marshmallow don't work? I mean, a root method that don't cause lost of DRM, functionality and so on?

It is not possible to root your device without unlocking bootloader for now.. Afaik you have to backup your TA by downgrading FW to LP, Then update to MM, Unlock bootloader, Flash Rootable Kernel, Flash Super SU, Flash DRMrestore..

Thank you very much for your attention.
So, for now, no root without unlock bootloader...
Thanks for the information...
