I am a bit surprised about the UK here: You mean that there's no independent retailers beside The Phone House that sells unlocked phones on all carriers, with the ability to get a contract with monthly installments on the unlocked phone?

In Sweden, the contract is seldom tied to a specific branded device, it is therefore possible to get unlocked products on contract with monthly installments that varies with the price and how much you want to pay per month. Then there's the possibility to buy from a carrier, some of them offers unlocked devices (Tele2).

I had the impression that a similar situation prevailed in the UK, i.e. that contracts isn't necessarily the same thing as locked and branded, unlike the US.
[Sony Xperia Z Ultra] baileyjr:
You are correct, and I was just as surprised as you to find out this is not the case with the Xperia range of devices. Every Android phone I have bought off a UK Carrier in the past has been able to be bootloacker unlocked. But there seems to be a specific issue with Sony Xperia Devices being locked.

You only have to have a look around the normal Xperia Z forum to see the problem exists. The Sony Xperia range seems to be the exception rather than the norm.

Sergey, you are wrong. And quoting epitomes of licenses applicable to certain parts of the Android source code found on Wikipedia isn't going to make you any less wrong.

Sony no Recovery partition！
[Sony Xperia Z Ultra] maquan:
I though that this topic is talking about root and how to root. But I post my question here 2 times and still being ignored.

I follow all the step correctly to unlock my bootloader, flash stock FW, fastboot system.img and flash again (all exception ticked) to wipe. But my phone always hang at Sony logo. Only flash again the stock FW make it boot normally, but also lost the root

I even try to relock the bootloader and unlock by flashtool (last time I unlock by Sony offical way) but still no success

How can I do now, please help
[Sony Xperia Z Ultra] ShALLaX:
Are you sure the stock FTF that you are using matches the version of the system.img that you are using?
[Sony Xperia Z Ultra] maquan:
I'm using all file from your link

stock FW is C6802_14.1.B.0.475_GENERIC Hong Kong.ftf

But before that I did upgrade to 475 via Bridge. Unlock bootloader by Sony offical way. Follow from step 33 and got Logo hang

I flash again the stock FTF, follow from step 21, logo hang

I than relock the bootloader and unlock again using flashtool, follow from step 21, logo hang

I did try on Window7, windows8 and Mac OS, all result in logo hang :(

What should I do now?
[Sony Xperia Z Ultra] ShALLaX:
Okay. Try skipping the last step (the wipe part). Get a clean stock ROM booting, then fastboot flash system system.img then try booting.
[Sony Xperia Z Ultra] maquan:
the same, still hang on the logo

---------- Post added at 09:52 AM ---------- Previous post was at 09:49 AM ----------

I know that the first boot will take about 5-10 minutes. So I also wait but over 15-30 mins it still hang on the Sony logo. How long is your first boot after flashing?
[Sony Xperia Z Ultra] epulrevo:
U make my day, i laught a lot. :D
[Sony Xperia Z Ultra] E90 Commie:
Could it be a problem with the USB ports or cable?

It seems like your computer somehow causes a corruption when it flashes the system.img.

I would try to download everything again and use a completely different computer, with a different USB cable just in order to eliminate those factors.
[Sony Xperia Z Ultra] maquan:
As I said, I tried on 3 different computer (win7, win8, Macbook) but still got the same situation

I also try to download the system.img file on other host (shared on Chinese website) but still the same. The stock FTF I can flash and boot normally so I think there is no problem with it.

Don't know what to do now :(
[Sony Xperia Z Ultra] GOF007:
Seem very strange indeed.

Mine got root successfully by just doing ONLY steps 41 and 42 :P
[Sony Xperia Z Ultra] maquan:
you unlocked the bootloader by offical way or by flashtool? I'm start thinking that my phone is defective or something T___T
[Sony Xperia Z Ultra] ShALLaX:
Get someone to md5sum the system.img and then compare it to an md5 that you generate.

That scares the f.....crap out of me, I'll hold on until an easier method has been found, hopefully there will be.
[Sony Xperia Z Ultra] crippenx:
Are you saying we can skip the long procedure Shallax had outlined and now follow your shorter steps?

We don't need to create our own system.img in linux, can download it from somewhere ... ?
[Sony Xperia Z Ultra] maquan:
Finally T___T I download again the system.img, check md5 with correct number, fastboot, and now it IS ROOTED !!!! I'm so happy. Thanks for your support hahaaa. Maybe the system file I downloaded last time is broken :)

but by using that guide I get the BLU LED color not the green one. Why?
[Sony Xperia Z Ultra] crippenx:
Where did you download the system.img file, maquan?

In Shallax' instructions is sounds like we created ourselves inside of linux distro --- then in the shorter steps on this page, it sounds like all of this can be downloaded ready-made? confusing.

Step 4 is not correct, the light will be blue (in fastboot mode) not green (flash mode)

And I recommend using Mac OS to root, because it did not require any driver installation as on Windows platform (that may caused errors or not compatible etc.)

Weirdest thing ... got my phone rooted after step 7. Rebooted it and downloaded SuperSu and updated the binary and was done. Didn't have to do step 8 at all nor did the HK version of ftf ever come into play .. how bizarre is that? I was already on the OTA 475 if that makes a diff ...?
[Sony Xperia Z Ultra] ShALLaX:
Yes, if you're already on 475, you don't need the FTF, nor do you need to wipe anything.

---------- Post added at 02:54 PM ---------- Previous post was at 02:32 PM ----------

It works!!! My Z Ultra is rooted, and bootloader is still locked! :)

All you need to do - is just enter some Chinese proxy server in Windows Internet Configuration, and after three tries - root!

Here are some working proxies.

Now to save TA partition... And our device will be ALWAYS rootable, with every firmware - because 475 kernel is, and we can just flash it - root it - and then update to newer one.

:) Great.

**Update**

Backed up TA partition with DRM keys intact, using DevShaft's tool 9.7. Everything works as it should. Root is complete, with System dir writable.

**Update 2**

Installed SuperSU 1.51 from PlayStore - it successfully updated SU binary, then pushed itself into System, replacing chinese Superuser. Busybox installed without any problems as well.

I wonder what rooting gurus like DoomLord or ChainFire would say about "360root" utility - it seems to use some completely new & unknown exploit. It would be great if they can learn this method and put it to good use - for example, to root Toshiba's newest tablets or other yet non-rootable devices.
[Sony Xperia Z Ultra] avetny:
exactly ! this is not just a root. It's smart root !

btw I just removed 149mb of garbage apks and root 360 apk is also there :P
[Sony Xperia Z Ultra] Andrewtst:
Don't have laptop now, try out tomorrow.

And ya, the new exploit is cool.
[Sony Xperia Z Ultra] corrado85:
so if we already rooted our phone using initial method, could the bootloader be relocked?
[Sony Xperia Z Ultra] avetny:
yes

---------- Post added at 10:53 AM ---------- Previous post was at 10:52 AM ----------

Drakosha if I will do factory reset my phone will be rooted ? Or I need to do all process again ?
[Sony Xperia Z Ultra] Drakosha:
corrado85, yes, but it won't do any good - DRM keys, once lost, are lost forever, so neither relocking, nor new FW flashing will ever restore Bravia or X-reality :(. Phone is basically damaged on physical level.

Root survives reset, if Supersu is moved to system. The only thing root doesn't like - is FW updates.

Can someone who knows DoomLord or Chainfire tell them about this new exploit?

P.S. BTW, it also means that the upcoming Honami is already rooted before it will actually hit the stores :)

I just check gfans (Chinese forum) - http://bbs.gfan.com/forum.php?mod=forumdisplay&fid=1329

Can double confirm Bravia Engine still working for image via at Album?

I ask this as someone mention at gfan forum where the one click root is unlocked - root - locked. If this procedure is real, then high possible the Bravia Engine / X-Reality no longer work.

But I also doubt about it, as I know.(at least in my previous Z), first unlocked need visit Sony site first.
[Sony Xperia Z Ultra] hoaianh2007:

[Sony Xperia Z Ultra] corrado85:
not a big concern. the screen is great as it is. but here is to hoping that future custom roms could allow us to enjoy x-reality? :)
[Sony Xperia Z Ultra] avetny:
It will not work if you unlocked bootloader.

(nothing to do with the root );)
[Sony Xperia Z Ultra] corrado85:
but as previously stated, even if you do lock bootloader again, the DRM keys are gone hence no more x-reality/bravia engine
[Sony Xperia Z Ultra] avetny:
:) 360 root didn't touch bootloder DRM keys partition at all. My bootloader still locked :)

[Sony Xperia Z Ultra] avetny:

[Sony Xperia Z Ultra] Andrewtst:
You all misunderstand me.

I ask this as someone at gfan site said one click root silently unlocked, root, relocked.

Even though I doubt about it as in my previous Z, if unlocked need visit Sony developer site and given them IMEI code to unlocked it.

So to 100% confirm it, checking Bravia Engine of working or not will know about it.

---------- Post added at 12:28 AM ---------- Previous post was at 12:23 AM ----------

Hi, can you check out the Bravia Engine to double confirm. Appreciate much.

Just untick Bravia Engine, view image at album, screen capture.

[Sony Xperia Z Ultra] Drakosha:
Andrewtst, you've frightened me pretty well, so I spent 10 minutes analyzing photos & videos precisely, using only Sony Album & Sony Video. I can confirm that Bravia Engine is definitely still there, and works great. Its effects are especially strong with cartoons, where there are large gradients & clean, vivid colors. So - no, bootloader unlock is not the case here.

[Sony Xperia Z Ultra] corrado85:

I requested sony developer site for unlock boot loader key and then root it originally.

[Sony Xperia Z Ultra] Drakosha:
GOF007, corrado85 - people, you REALLY should consider getting a better monitor, if you don't see the difference in color vibrancy & contrast. The upper picture is without Bravia. Both taken from fixed-mounted Galaxy S4.

And these screenshots, BY THE WAY, are NOT from "My little pony" series, these are screens from fan-made music video "Children of the Night" - wonderful & magical piece of art, not kiddie movie.
[Sony Xperia Z Ultra] corrado85:
I was just kidding <3

:good:

I agree with you, I do spot the difference as you're stating
[Sony Xperia Z Ultra] Andrewtst:
Just screen capture. Screen capture is showing the different. A lot people did before, not only me. Screen capture of Bravia on or off can see different. No need photo taken.

[Sony Xperia Z Ultra] unk_damnation:
It is a bit hard to differentiate those two pictures, mainly because the artifacts from the camera itself..

[Sony Xperia Z Ultra] LordManhattan:
Yeah, someone should tear that thing apart and see exactly what it does. I just find it strange that this thing just "showed up" and does magical things that no one understands.
[Sony Xperia Z Ultra] Drakosha:
Hi.

Interesting new info. During my experiments with Bravia Engine, I found out (and can confirm to 100%) that it works not only with Sony apps, but at least with MX Player also. That means, BE is indeed implemented on driver-level, and will be used by any hardware accelerated player. Same, I'm sure, applies to the upcoming X-Reality - so consider twice before unlocking bootloader.

Any sufficiently advanced technology is indistinguishable from magic (c) Arthur C. Clarke. Before 360root, there was "Perfect Event" exploit that did the very same magic, before it - there was "Motochopper", before that - "Zerg Rush" etc. Nothing to be afraid of. :)
