Someone to help me? Ot the only thing I can do is hit the phone on the floor and throw it away

Now I regret very much not to buy Note III. There are very good developers and here I will have a very expensive brick to hit my head with it.

If I go to sony service they will see that my phone is modifies and dont have guarantee.
[Sony Xperia Z Ultra] jnocomski:
Yeah, what I was thinking as well. Plus I got the C6802 version and then somebody bricked theirs. Now I'm scared to even consider doing it! :eek:
[Sony Xperia Z Ultra] baileyjr:
It's not complicated, flashing zip from recovery is by far the easiest and most reliable way to achieve root. You just need to make sure you are bootloader unlocked.
[Sony Xperia Z Ultra] jnocomski:
Yep, I've flashed a lot of custom ROMs from recovery on my previous phones (HTC One V, Samsung Galaxy Tab 2, Nexus 7, Nexus 4, Note 2), I'm just thinking twice with Sony as I've only recently moved to one and I'm not yet accustomed to using flashtool. :good:

What about Emma Flash tool for Xperia devices did you try it

[Sony Xperia Z Ultra] hykhleif:
me to i miss the old exciting note 2 days as all here it is mumbo jumbo
[Sony Xperia Z Ultra] natispain:
I need good entire firmware to rescue my phone, I dont find it anywhere.
[Sony Xperia Z Ultra] chemcup:
so you try Emma? Doesn’t work!

You phone is unlocked!
[Sony Xperia Z Ultra] baileyjr:
I think there is an even easier solution for those with unlockered bootloaders.

Step 1: Flash the new firmware ftf using flashtool. Theres a fully working ftf for c6833 here: http://xdaforums.com/showthread.php?t=2489892

Step 2: Flash the new V4 kernel and recovery from this thread : http://xdaforums.com/showthread.php?t=2426739

Step 3: Reboot the phone to CWM mode and install the UPDATE-SuperSU-v1.65.zip found here: http://xdaforums.com/showthread.php?t=1538053

Step 4: Reboot and enjoy.

EMMA

I have to wait thry to aprove my registation. But is too long.
[Sony Xperia Z Ultra] Blacklistest:
after Step 1 then go to Step 2.. it mean u install CWM.. as i know CWM need to be rooted first bro..CMIIW

i think OP already wrote easy method to understand
[Sony Xperia Z Ultra] baileyjr:
No your wrong you don't need root for this CWM, you do however need unlocked bootloader to flash zip from CWM to gain root.
[Sony Xperia Z Ultra] Blacklistest:
have u u try it bro??

read at : "navigate to the resulting directory and look for

If you have SuperUser installed on your phone: superuser.bat

If you have SuperSu installed on your phone: supersu.bat"

how u get SuperUser or SuperSu installed before rooted? i know we can installed it but u dont have binary inside..n how to get CWM permission inside adb if u dont get rooted???
[Sony Xperia Z Ultra] baileyjr:
Damn your right.... I forgot about that bit lol My bad.. I take it all back... :o

In my head I was thinking of sending the kernel/recovery via fastboot.
[Sony Xperia Z Ultra] abuihsan:
came from .532 and then unlock the bootloader, ran step 1 and then step 2

on step 2: I flash v5 kernel using this method->

I download the adv-stock-v5.img file, then I put it in the sdk>platform-tools folder on PC, then

connect the device with fastboot mode, then

opened the (folder on PC) sdk>platform-tools and then (SHIFT+right click) and choose 'Open command window here', then a prompt will popup like this:

... \sdk\platform-tools>

on the blinked cursor I type this: fastboot flash boot adv-stock-v5.img

and I got CMW recovery (...install superSU zip, flashing ftf - only the kernel, and I got my device rooted)

the question is: is actually the device already (or still) rooted after step 1? or (if not rooted), so the CWM can be flashed without rooting the device?
[Sony Xperia Z Ultra] baileyjr:
The CWM can be flashed via fastboot without being rooted as long as you have unlocked the bootloader.

You weren't rooted until you flashed the SuperSU.zip

Now that you have root you flash this to get custom recovery back http://xdaforums.com/showthread.php?t=2426739
[Sony Xperia Z Ultra] chemcup:
You don't have to register or get validated for EMMA

Did you Copy the Customization.ini file. You find it in the Flash_tool_for_Xperia_1.zip. and Paste it into the installation folder.

Windows 64 bit is: "C:\Program Files (x86)\Sony Mobile\Emma\"

or Windows 32 bit is: "C:\Program Files\Sony Mobile\Emma\"
[Sony Xperia Z Ultra] natispain:
Finally, I return yo 532, root with Vroot and will wait to apear better root for new actualizations.

I revived my phone but I tried so many things and I dont know hiw I did this.
[Sony Xperia Z Ultra] nihal1983:
works well for me
[Sony Xperia Z Ultra] maquan:
I will wait for a method that's not required boodloader unlocked. I'm fine with 532 now :D

[Sony Xperia Z Ultra] dyepnoodle:
Question here. Im about to do this process and i want to relock my bootloader by restoring TA, here's the process ill try. Backup ta, unlock, install recovery, flash supersu, reflash stock 257 kernel then restore ta. Will this process work? Will the device stay rooted? Sorry this is the first time i deal with a locked xperia. Been unlocking xperia phones since the X10 days.
[Sony Xperia Z Ultra] Reb0rn:
Sounds about right. Should work brilliantly.

[Sony Xperia Z Ultra] keithleyson:
my phone get's stuck in the boot animation. I can get into CWM - not TWRP - but cant boot the phone normally.
[Sony Xperia Z Ultra] baileyjr:
You need unlocked bootloader to root using this method.
[Sony Xperia Z Ultra] keithleyson:
my bootloader is unlocked. It's just that the .532 kernel with CWM will not boot .257.
[Sony Xperia Z Ultra] nihal1983:
flash the 257 kernel

if you read the op is that after you flash the 532, you need to relfash the 257 kernel via flashtool, for this select all the other options except kernel in the EXCLUDE section
[Sony Xperia Z Ultra] keithleyson:
Yeah. that's what I did and it works. What I was thinking was maybe I can still keep the 532 kernel so I can have CWM even with the the 257 fw.
[Sony Xperia Z Ultra] nihal1983:
nah unfortunately not yet.
[Sony Xperia Z Ultra] clubtech:
Yes this works. I've done it myself. Obviously u need to make sure u have your TA partition backed up before you unlock bootloader.
[Sony Xperia Z Ultra] dyepnoodle:
Dude one last question. How can i verify if i have successfully backed up my phone's TA?
[Sony Xperia Z Ultra] iBuzman:
I've just managed to "mash" together a deodexed rooted 257 rom that is cwm flashable and recovery is maintained :)

I'm not a dev and wouldnt publish a copy-paste of [MENTION=4340984]krabappel2548[/MENTION] 's work - but maybe we should ask him nicely for a port of it to stop all this stuffing around with multi-step flash processes :)

I still get boot loop :S

Oh well, I will wait.
[Sony Xperia Z Ultra] JadHusin:
Hi! I'm so very sorry if I sound so dumb. But I really don't get this. Can you please give me a step-by-step guide to root Z Ultra (C6802). I know for the latest update, .257, to root it, we have to unlock BL. But, that'll cost us the X-Reality and DRM stuff. There's a guide to do a backup but how to restore after unlocking BL?

How to unlock BL?

I rooted my ZU before but I just used vroot.

Help, maybe?
[Sony Xperia Z Ultra] LordManhattan:
Downgrade to 532 again and root it. Then install OTA Root Keeper and update through OTA. No unlocking of the bootloader is necessary.

Yeah, I saw it but I wanted to make sure that someone could verify it. Fortunately I found a post in a German forum of someone who tested it. After that I tried it myself and I can confirm that OTA Root Keeper can help you to keep root if you do an OTA update.

[Sony Xperia Z Ultra] JadHusin:
Did not work for me. I downgraded to .532, rooted it, installed OTA RootKeeper, backed up the root, updated to .257, opened OTA RootKeeper and no restore root option. I tried twice. How did it work for you? :confused:
[Sony Xperia Z Ultra] chemcup:
are you updating using computer, is not going to work ! the RootKeeper works only when updating via OTA.

[Sony Xperia Z Ultra] Dean-O:
So I'm on the new firmware... and don't have a TA backup that I'd like to have before unlocking the bootloader in case I decide to revert... which requires root to obtain... so I'm stuck for now? Is there a way to obtain temporary root?
[Sony Xperia Z Ultra] baileyjr:
Doengrade to 532 firmware usen flashtool the root using vroot. Then you can backup TA before upgrading the firmware again.
[Sony Xperia Z Ultra] Dean-O:
But isn't it advised that I backup TA before flashing anything? E.g. http://xdaforums.com/showthread.php?t=2428590

Jeeez I am confused. Right guys, can we just make this very simple please, I will even start a new thread if needed.

Can we very simply explain , without references to threads of 14 pages which subreference to threads back to another thread.

Everyone is confused including me and I have like many others, flashed android phones for last four years or so starting with ZTE blade (long time ago)

Ive been trying this thread and got lost now. My phone boots, can get into CWM or TWP , but after a cold start it reboots before getting into the welcome screen.

Confused !!

1. I was on .510

2. So, I downloaded a tool (god know where - I cant remember its been that convoluted) which backed up my TA

3. I used Sony site to unlock my bootloader.

4. Downloaded FlashTool and drivers - installed drivers.exe in the drivers folder [after unzipping]

5. Downloaded version .257 and flashed this using flashmode in FlashTool - all ok. 257 from here https://mega.co.nz/#!jFMX1bCS!d2kA1AezDnXK6g8ZWrXN2DnLkTExaj9un96P0Dge4nA

6. Downloaded combined kernel/recovery file called adv-stock-v4.img and flashed this in fastboot mode using FlashTool selecting fastboot mode and clicking "Flash Kernel" - all ok

7. Rebooted to TWP by holding volume down when SONY logo appeared - purple LED - entered TWP - all ok

8. HAd UPDATE-SuperSU-v1.zip on my external SD card (again cant remember where I sourced this, got lost in that many threads)

9. Used TWP to install the SuperSU zip - all ok

10. Put the phone into flashmode by powering off and holding volume_down whilst connecting usb to pc.

11. Fired up FlashTool, selected flashmode and used the same file as in 5 above but this time excluding everything but the kernel, flashed - all ok

12. Reboot - get to welcome screen, set up phone, try SuperSU - phone is rooted. Great!

13. Reboot - cannot get into CWM or TWP - lost them

where have I gone wrong - how do I get CWM or TWP back?

phew!!! thanks

EDIT:: WORKS! Had to download XZU & Z1 Recovery v4 for Windows from the 1st post in this thread http://xdaforums.com/showthread.php?t=2426739

Unzip and run the run.bat file

Now all is okay. Dual Boot, .257 latest firmware, rooted! Great.

I have no idea how I did this, spent last two days all over XDA threads cross referenced, but if anyone would like me to edit/improve this post, let me know what info you need.
[Sony Xperia Z Ultra] LordManhattan:
Just reinstall them. It only takes a minute. There's a short guide and download link in the original android development section.

[Sony Xperia Z Ultra] Ciex:
A question. Do you loose the TA file if you do this process?
[Sony Xperia Z Ultra] LordManhattan:
No.
[Sony Xperia Z Ultra] blueether:
because you have already backed it up before you unlocked the bootloader (see beginning of OP - using the unlocked bootloader)

I think the other thread works for locked bootloaders
[Sony Xperia Z Ultra] Reb0rn:
This works on the new C6833 14.2.A.0.290 firmware too. Just so you guys know.
[Sony Xperia Z Ultra] LordManhattan:
Have you done it yourself? Also, do you have recovery?
[Sony Xperia Z Ultra] techpal:
If I can get C6802 ftf will follow this procedure.I am on unlocked bootloader.

[MENTION=614742]Reb0rn[/MENTION] : is the C6833 14.2.A.0.290 fw the latest 4.3 one? and is there a ftf available anywhere? please advice. thank you!
[Sony Xperia Z Ultra] Reb0rn:
I'm having some issues with SuperSU and 4.3 update. Its like i have root but not really... Like half root :eek:

Im able to freeze system apps but not delete them. (Titanium backup)

But terminal gives me root access.

RootExplorer is unable to mount system as R/W

ADB gets full root too...

Something is fishy here...

EDIT:

Oh ****z i think i know why... The kernel i used was a 4.4 kernel with cwm. Then i tried a stock but those are 4.2 with cwm...

Im gonna try with cm10.2 wich is 4.3 kernel with cwm before reverting to original stock kernel.
[Sony Xperia Z Ultra] abuihsan:
hi.. did you use supersu v1.65 or the newest v1.80? thanks!
[Sony Xperia Z Ultra] Reb0rn:
OK here goes.

Ive tried with 3 different CWM Kernels (Stock 4.2. Krabappels 4.4 cwm, CM10.2 CWM)

And tried 3 different SU's (SuperSU 1.80. Regular Superuser. And Koush Superuser)

I get some kind of partial ROOT but not full root. I am able to freeze apps /With titanium backup\ but not able to mount SYSTEM as WRITE in any way. I restored my TA partition and that partition has full read/write and could lock and unlock my bootloader and restore TA.

Its like it has root but not on the /System folder.

How is that possible??

As of now im out of ideas... we must wait for a special root tool. As it seems, not even OTA will work on this...
[Sony Xperia Z Ultra] abuihsan:
Ok I am waiting the ftf.. will just try with supersuv1.65

maybe also with v1.85 which has these changelog:

15.12.2013 - v1.85

- Fix su to non-root user on 4.3+

- Fix su permission reset on 4.4 (will not be an issue until Samsung comes out with stock 4.4 ROMs)

- Fix am crash due to external storage not being defined

- App now offers to install backup script if ROM supports it

- Expand trust system setting to include all higher-than-shell users

- Added credits display

- Completely removed nag capability

- Lots of code changes

^^ ah well, worth a try - instead of updating and then trying to root I'm attempted to build a rooted rom, so I'm a little way off testing which method may work.

Yup if we update with superuser binary root totally gone.. At least with only supersu165 I am still be able to restore apps and data with TB, also few root-needed-apps still works.

No luck here after all. /system seems to be locked write-only all the time, even if SU is installed. Tried even SU from CyanogenMod. Looks like SONY locked that with the kernel or something.
[Sony Xperia Z Ultra] LordManhattan:
I find it strange that Sony hasn't made it easier for us to root. They served some AOSP goodies for some Sony devices last week (not GPe), and the Free Xperia Project (FXP) is a collaboration between Sony Mobile and XDA devs. They let us unlock the bootloader, so why can't they do the same with rooting?

I am hereby going out on a quest for easy rooting.
[Sony Xperia Z Ultra] YrrchSebor:
I am getting the sense it has more to do with Android 4.3 than anything Sony has done?

http://www.androidcentral.com/android-43-and-beyond-root-going-away-stock-roms
[Sony Xperia Z Ultra] LordManhattan:
Sure, but imagine if Sony had a simple tool/instructions like their bootloader tool to root? We're voiding our warranties when we unlock the bootloader, and it's the same story for rooting, so why not? Only devs and XDA people would use it (i guess), so it's not like the average dude on the street would delete his system folder :p
[Sony Xperia Z Ultra] YrrchSebor:
heehee, yeah, we here all have to have root! it sounds to me like Google is trying to make the OS more secure, since there have been plenty of reported malware and security holes in Android. of course the result is less freedom for us hackers/modders/fiddlers! it sounds like we might have to have custom kernels in addition to simply flashing su. i could be wrong, this is just my layman's understanding from what i've read so far :p

After reboot its back to common "partial root". The problem is in the kernel, as i can understand.

As i know, we need a custom kernel to run init.d scripts.

Anyway, we need a custom kernel now, for that time i can wait with this temporary decision. Xposed working great, no need to do anything more for now.
