No, we don't. I'm also living in India currently and bought my phone here.

You're thinking of locked to a carrier which is true, this doesn't happen in India. This is completely different then unlocking your bootloader which will always come locked by default with this phone. You can't install a custom ROM with a locked bootloader unless it has a stock kernel (means no AOSP). Sony helps us unlock the bootloader but it voids your warranty and until there is a fix it breaks the camera (until you restore your TA partition which fixes the camera but re-locks the bootloader).

For phones that are locked to a carrier, the only difference is that Sony often won't let them unlock the bootloader. In India you can unlock the bootloader, but again it won't come this way.. you have to do it.

I would suggest you read up a lot on this thread and do some Google searches to learn a bit more about rooting and bootloader unlocking before you try installing anything on your phone.

Yes Sir, that's the correct version and operates on LTE Band 4.

The C6906 will work with both T-mobile and AT&T LTE (Band 4 and Band 17), but it's not out yet.

I couldn't wait, so I ordered the C6903.

Help

May be out of luck from what I have been reading. Is the TA backup specific to each device? I have unlocked without the TA backup and of course cam doesn't work. Can I use another TA partition from another z1 and if so, is anyone willing to share?
[Xperia Z1 Android Development] crazymister:
if you use another persons TA you will HARD-BRICK your Phone, turning it into a paperweight.

Wouldn't recommend you to do it ;)

I tried 360Root but this software is unable to install in Windows 8.1 ;( It states that "Only support Chinese OS"
[Xperia Z1 Android Development] cajunflavoredbob:
Downgrade to .534, root, then install a pre-rooted .257 or this ROM directly.
[Xperia Z1 Android Development] crazymister:
Or install .534 DK ftf, root, and do ota to 257. Worked fine here for my buddies phone.
[Xperia Z1 Android Development] cajunflavoredbob:
I'm surprised the update doesn't remove root in the process. That's very interesting.
[Xperia Z1 Android Development] crazymister:
Only ota works. Via pc doesn't. That's because the ota update is incremental, and the pc update isn't.

Plus its less of a hassle, because you don't have to install a recovery or download another update.zip. You can just let your phone do the work
[Xperia Z1 Android Development] cajunflavoredbob:
That makes perfect sense.
[Xperia Z1 Android Development] vodanhdaisu:
Can you please give the download link for the .534 DK ftf

Thank you

[Xperia Z1 Android Development] dlads:
Hi all,

Coming from a long line of HTC devices and a single Samsung device, i'm a little lost here, i'm reading through the posts made and i have all the tutorials here in place and all files besides the ftf file needed for firmware.

The problem i have is that the noob guide which i have to follow is for so many devices i'm not sure which sections i need to stick to or not.

So as far as i'm aware, in order, I have to:

Use the flashtool to flash a firmware (i have no idea which one or where it is)

Root the device

Back up TA files for DRM

Unlock bootloader

Restore TA files then that makes the camera work again.

Flash a custom rom <-------- basically where i'd like to be

Apologies for being a noob but like i said this is my first Sony.

Even more apologies if this is completely the wrong section to say all this, i've had a long day in work and i'm just trying to get this sorted.

Many thanks in advance for any clarity on any of this. :)

And again, sorry if in the wrong place. :(
[Xperia Z1 Android Development] 301stSpartan:
To answer, it depends what custom ROM you want. If you want AOSP, then there's no way to have a working camera currently. Sorry. If you want a stock based ROM then you don't need to unlock the bootloader.

Restoring the TA partition (to fix the camera) also re-locks the bootloader. So if you restore the TA partition then you can't use any ROM that doesn't have the stock kernel (so no more AOSP).
[Xperia Z1 Android Development] dlads:
Quick response, cheers for that, crazy that the camera gets broken, i've never known it on any device i've had.

It's fine that i can go for a stock rom, just need root access really, i've got a shed load of apps itching to get on this device from titanium.

But as far as you can see I can go ahead and go through what I wrote? Minus the bootloader unlock right?

Thanks for replying by the way, i appreciate it.
[Xperia Z1 Android Development] 301stSpartan:
Kind of depends what version you're on now. If on 534 or earlier you can just root. If on 257 you have to flash a 534 ftf, and then root.

To get from a rooted 534 to a rooted 257 you must either:

- upgrade via OTA (PC Companion won't work to keep root)

OR

- install a recovery and flash a pre-rooted 257 ftf

OR

- install a recovery and flash a stock based custom ROM (I'm on monxdified and love it)

You're welcome :thumbup: Going to bed though, but hope you have what you need or else someone else should be able to answer.
[Xperia Z1 Android Development] dlads:
I'm on 518 and i went and did a risky thing and rooted anyway using the vroot method, i've also backed up my TA files onto my computer so i guess i'm pretty much set.

So i need a recovery now and a rom.

Cheers m8 :)
[Xperia Z1 Android Development] shubh_007:
First of all I don't have an Xperia Z1.

I think you could simply do an OTA update. That'll let you keep root and also update the phone. If you can't do an OTA update you'll now be needing pre-rooted 257 rom and recovery. Or recovery and stock based rooted rom. :)
[Xperia Z1 Android Development] dlads:
Sorted now, what i did was, grabbed an FTF file for 534 because updating it to 257 broke root, so went back to 534, then rooted, then installed custom recovery, then installed custom rom, then flashed only the kernel and baseband from a 257 rom.

All is well again. :)

Cheers.

Any user have EMMA login?

Need 14.1.G.1.534 of 6943 Z1 version. (device was unstable after flash without wipe data\system\app log and lost digital tv)
[Xperia Z1 Android Development] gregbradley:
You do not use EMMA for this

You need to download the original flashtool from http://www.flashtool.net/

then use it to flash a FTF from the mega collection thread in the general section
[Xperia Z1 Android Development] Luhccas-X10:
I know dude.

I want to download the older version for the 6943.

We can do this only with EMMA.

Sent from my Xperia Z1
[Xperia Z1 Android Development] gregbradley:
Which version? FW is FW, if you want 14.1.G.1.534 then any of them will work, or flash the new version again and this time wipe data etc.

And EMMA is only for an unlocked bootloader....
[Xperia Z1 Android Development] Luhccas-X10:
EMMA isn't for unlocked bootloader. It's the official Sony program of service center.

There you can choose which version to download and flash using it. (i just want to download a version)

The files are the same of Sony Update Service or PC Companion to make a .ftf bundle.

And,don't. With any other version I'll loose some functionalitys like digital TV and some regional apps.

This is why i'm asking ;)!

[Xperia Z1 Android Development] cajunflavoredbob:
If you didn't follow the instructions that said to backup your TA partition BEFORE you unlock your phone, then you're screwed. You cannot use anyone else's backup, since they are specific to each device. If you do restore someone else's backup, you will brick your phone.
[Xperia Z1 Android Development] gregbradley:
You are wrong, Emma can only be used on boot loader unlocked devices, a quick Google search will show you I am correct. And the Z1 is not supported by Emma yet anyway so even if you have unlocked the boot loader you cannot use it on your device.

---------- Post added at 08:17 PM ---------- Previous post was at 08:16 PM ----------

As I said before, I can upload mine, but if you use it you will PERMANENTLY HARD BRICK YOUR PHONE.
[Xperia Z1 Android Development] Luhccas-X10:
The question isn't about being right or wrong man...

I just ask about who have EMMA user.

If you think that a simple google search will solve "my mistake",well...

Ok,then :)

Six years working with db20**,db30**,db31**,A1**,two years as Sony Ericsson employee makes me know what i'm searching for.

If you can't help just say "i can't help you". It's the right way of behavior and friendliness.

By the way,thank you.

Being that you worked for Sony Ericsson, wouldn't "you" have a login for this program?
[Xperia Z1 Android Development] gregbradley:
I can help, you are going about this the wrong way, Emma will not help you doing what you are trying to do. You need to find someone with the FW you want and they make the ftf using pccompanion/sus files and the original flashtool program.

By correcting your error I am helping you. I don't have the ftf you require but an Emma login won't help you either...

EDIT

http://developer.sonymobile.com/services/flash-tool/

1)Please note the line that says "This flash tool can only be used by Xperia™ devices having an unlocked boot loader."

2) Please note the link for supported devices, click on it and see that Xperia Z1 is NOT on the list

3) Please note the warning about using EMMA, in that it wipes user data, so you may as well try my original suggestion of flashing the 257 for your phone FTF in the original flashtool and wiping data to avoid "Laggy OS"

4) Please read this and note what the moderator says in the first post

So you actually do NOT EVEN NEED A LOGN AND PASSWORD.

I am/was being friendly, I am helping you by pointing you in the correct direction.

You do not have to listen to or like my answer, but it is the correct one.
[Xperia Z1 Android Development] Luhccas-X10:
It's NOT the flash tool...

It's the service software that you use at service center.

The one who have a proper login and password and inside it you have lists of a lot of stuff.

It's something to use with a dongle if necessary. (not the case here)

Just forget it.

You don't understand what I mean but I appreciate your effort trying to enlighten me.

For the last time,thank you.

[Xperia Z1 Android Development] gregbradley:
If this is the case and you have a copy of this, then since you are an employee, and have rights to use it, you should have your own login and password. If not, then ask your colleagues for theirs, I don't imagine anyone here would have or share one.

You asked for EMMA login

Hi guys - please be patient with my - I am coming from i9100 where odin made things really simple -

I get my new z1 tomorrow, from all that I have read I understand that my new device will probably come with 4.2.2 so to get root and flash custom kernel/rom I need to take these steps:

check bootloader is unloackable

root using vroot

update to 4.3.1

back up TA with TAbackup - not sure if this is necessary now?

unlock bootloader using flashtool (will this allow me to re-lock in case I need to claim warranty repairs?)

install doomkernel with flashtool

flash custom ROM in recovery

Any help very much appreciated :good:
[Xperia Z1 Android Development] westernmg:
You don't need to root the 4.2.2, just update to 4.3.1 and unlock the bootloader.

TA Backup is not needed since we have Sonys fix in the 4.3.1 ROM.
[Xperia Z1 Android Development] 301stSpartan:
I think you should back up the TA to be safe. 4.3.1 fixed the camera issue but I think the bravia engine isn't fixed for unlocked bootloaders. I could be wrong, but better safe than sorry.
[Xperia Z1 Android Development] Jsilver73:
Can you tell me, if I unlock the bootloader using flashtool does this negate the need to obtain unlock code from Sony and thus leave us free to relock the bootloader and thus regain warranty? Is there a way to unlock bootloader and still keep warranty?

Thanks
[Xperia Z1 Android Development] 301stSpartan:
If you back up the TA partition you can restore it and relock the bootloader and you should be fine on the warranty. Doesn't matter how you unlock. Even if you request the code from Sony, once you restore the TA then they won't know if you ever used it or not. There may be a counter or something, I'm not sure, but from experience and from reading on here, warranty is fine if you relock the bootloader.
[Xperia Z1 Android Development] Envious_Data:
Since unlocking your bootloader wipes your TA partition (i think) wouldent that wipe your drm keys and thus stop the camera from working or is that no longer the case with xperia Z1 anymore?

Also to you would there be any use building aosp or Envi-OS Touch for xperia z1 or is that something that should be left for the uber pros?

And again is xperia z1 simple to work with like xperia s or is it more complicated and has alot more that you have to work around just to do any one thing?

(kinda like a samsung or something)
[Xperia Z1 Android Development] 301stSpartan:
To answer just your first question, the camera breaking on ULBL bug was fixed by Sony with the 4.3 update. You still use other DRM enabled features though, such as the Bravia engine
[Xperia Z1 Android Development] Envious_Data:
Hmm

Ok only bravia engine or is there any others to add to the list because bravia engine i dont care for

Also could you spesify build number please (thanks)(future uses)

You don´t have to unlock your bootloader to install iHackers ROM. However you need unlocked bootloader to install custom kernels.
