[Sony Xperia Z Ultra] IchiGoQc:
I have a c6806 from Bell and I don't mind testing that method.Is there a chance to hard brick my phone with that method !? I don't mind ending up with a boot loop, I just want to be sure that I will be able to enter flashmod to flash .FTF file if something went wrong !!

EDIT : NWM I tested and it doesn't work with c6806 from Bell, no sony's logo or whatever only a vibration when attempting to turn on phone.

I was already on .532 rooted and XU Dual recovery. So I download Dogg Rom 4.4 for c6806, wiped data from recovery, flashed rom, flashed XUrecovery zip file. Then I went to advance settings to power off the phone, I started FlashTools with only Kernel selected from .290 official rom. Then disconnected from computer, attempting to start and nothing happen .... loolll. I tried to enter flashmode (cross fingers) it worked, flashtools said device in flashmode. So I flashed .532 rooted, installed XU recovery and proceeded with restoring previous nand backup.

Was I doing something wrong !?
[Sony Xperia Z Ultra] IchiGoQc:
I also tried the OTA update but fails when attempting to flash, phone reboots and when back to OS says could not install. I verified the CDA seems ok to me, tried factory reset before OTA, same thing, tried to unroot device while on factory reset same thing. I'm kinda out of idea on how to get 4.3 via OTA, I want to try to keep root while updating to 4.3.

Is it verifying customerid ?! Cauz mine has 4 digits instead of 3 of what I seen on other thread !
[Sony Xperia Z Ultra] blueether:
I dont know if OTA and rootkeeper will ever work for going to 4.3, but you shouldn't need that if you follow the guide in the OP, unless you are on a carrier locked phone (I'm looking at you Bell).

Thanks for testing, a shame that it didn't work on the Bell version

I'm wondering if someone could test it missing out step 14 to see if it will boot doggrom with a stock kernel? You will end up with a partly rooted phone without write to system if it boots...

[MENTION=4642591]hamdogg[/MENTION], you have any ideas?
[Sony Xperia Z Ultra] hassanmahmood:
Thanks so much for testing that - I was going to try and find the balls today - on some level I'm glad that you tried and failed instead of me, lol.

I can't believe that though; no matter what method you try employing it seems that Bell has thrown a wrench in the works.

It's really ****ing ludicrous.

It seems there just isn't a way to have root on .290 on a C6806 - (I don't know anyone who has this version of the phone that is not on Bell)
[Sony Xperia Z Ultra] blueether:
I cant see why it's not working, if it will boot with ZU recovery on .532 ???

I'm wondering is the stock kernel didn't flash or if you need to flash the boot stuff as well on th 6806??
[Sony Xperia Z Ultra] jackie099:
dont worry! i will try to make a stock c6806 flashable rom with root tonight.
[Sony Xperia Z Ultra] hassanmahmood:
Look forward to it.

Thanks a lot!
[Sony Xperia Z Ultra] IchiGoQc:
Ya I'm looking forward to it. I want to be on 4.3 it was a smoother experience than firmware. 532 which I'm stuck to because we can't have the. 257 ôta update anymore since. 290 was released well for me loll and without root it's no go can't live without root. Next time I won't take a phone from a carrier I hate ducking hate being restricted. I bought that phone so I should be able to do whatever I want with it.

Thanks a lot all for your help :)
[Sony Xperia Z Ultra] Jordicf:
Could anyone confirm does it work for locked bootloader 4.3 firm? I only wanna flash when locked bootloader be free, but LTE not losses too. Thanks for your work since Catalonia.

[Sony Xperia Z Ultra] IchiGoQc:
Looks like it works for 6802 and 6833 models but not for C6806 from bell not sure if the us version is working. Your best guess is to try trust me the worst thing thats gonna happen your phone won't boot ;)
[Sony Xperia Z Ultra] android_myan:
Thank Jackie099. Your C6833 Rom make my ultra back to LTE. :)

C6833 Rom run smoothly now.:good::good::good:
[Sony Xperia Z Ultra] jackie099:
I am uploading for C6806. Anyone wanna wait and test?
[Sony Xperia Z Ultra] hasablack:
can you explain me the steps for 833? i tried to make it, but my cell just reboot and reboot
[Sony Xperia Z Ultra] jackie099:
are u sure u completely follow the guide and wipe everything correctly?
[Sony Xperia Z Ultra] jackie099:
https://mega.co.nz/#!MsETnaoY!CVex3l5-Ta4e8Ob-FYFeuiBS1FM3wxrLPhs68zuZjcY

try if it works
[Sony Xperia Z Ultra] IchiGoQc:
I DID IT MOTHER****ER ..... loll I didn't try with your file though but many thanks for your help. What I did is as follow : Wipe DATA from recovery, Flash Doggrom whatever version it is now I think 4.5 is coming I didn't flash XURecovery, power off the phone, flashtools .290 FTF from sony official ROM excluding ALL except BOOTBUNDLE and Kernel, reboot enjoy DoggRom rooted :)

Thanks to everyone who helped, really appreciated.
[Sony Xperia Z Ultra] blueether:
Full root? I would have thought you would need to flash th XU zip from recovery to disable RIC.
[Sony Xperia Z Ultra] IchiGoQc:
Ya maybe I don't have full root since I can't mount /system as RW lolll

---------- Post added at 04:12 PM ---------- Previous post was at 04:00 PM ----------

If I flash Xu from recovery and then flash the bootbundle from Sony firmware will I loose the dual recovery?!
[Sony Xperia Z Ultra] blueether:
Do what you did but flash the XU zip after doggrom, I wrote a guide earlier in the thread that works for useing [MENTION=4642591]hamdogg[/MENTION]'s rom and getting full root with a locked BL - even has recovery.

I dont think you need to flasg the bootbundle, just the kernel. if it doesnt work just flash the boot boundle from flashtool. If you lose recovery it is ok as you will have full root in doggrom to run the XU script from the PC to re-insert the recoveries.
[Sony Xperia Z Ultra] Justin^Tan:
do we have to go back to 532, or can skip that and go straight from .257 rooted?
[Sony Xperia Z Ultra] blueether:
As long as you are rooted it should work
[Sony Xperia Z Ultra] IchiGoQc:
The problem is that I didn't have full root the first time I had to flash the bootbundle and I had supersu in dogg tom but wasn't able to enable re in / system so root was incomplete and no recovery.

So I switched back to. 532 excluding baseband rooted and then I did it again and this time I flashed the recovery zip file and in flashtools I excluded everything except kernel and it works this time without the bootbundle. Now I have full root I tested I can mount /system in rw.

Thanks again
[Sony Xperia Z Ultra] blueether:
Yes I knew that would be the case, that is why it was preceded with "Do what you did but flash the XU zip after doggrom, I wrote a guide earlier in the thread that works for useing [MENTION=4642591]hamdogg[/MENTION]'s rom and getting full root with a locked BL"

Read what help people post and life will be easier ;)
[Sony Xperia Z Ultra] IchiGoQc:
I read ahah but you suggested to try without step 14 which I did and I though that with root anyway I could install recovery at later time but thanks again

---------- Post added at 07:55 PM ---------- Previous post was at 07:53 PM ----------

The first time I followed your guide and it didn't work I ended up with no Sony logo or whatever ;) I'm glad we made this through
[Sony Xperia Z Ultra] hassanmahmood:
So you have full root on a Bell Xperia X Ultra?

Is there any way to have full root on a stock .290? Or must it be the custom ROM you are using?
[Sony Xperia Z Ultra] IchiGoQc:
Maybe if you use jackie009 technique but I only tested with dog's room which is pre-rooted. But it is stock rom from what it's look like he just improved it. I'm really satisfied with 4.3 until now, it's way smoother than. 532.

So ya I'm 4.3 full root now
[Sony Xperia Z Ultra] hassanmahmood:
You're on Bell right?

Do you have fully functioning 4G/LTE?
[Sony Xperia Z Ultra] IchiGoQc:
Yep I'm with bell you won't have network until you add manually bell apn but that's not an issue once you do you will have LTE.
[Sony Xperia Z Ultra] hassanmahmood:
Does X-Reality work?
[Sony Xperia Z Ultra] IchiGoQc:
I don't know butting guess I see the option and it's checked
[Sony Xperia Z Ultra] hassanmahmood:
I'd still rather have stock 290 with root if it is at all possible.

Although, could someone tell me, what's the difference between Stock 290 and DoggRom?

---------- Post added at 11:49 PM ---------- Previous post was at 11:28 PM ----------

Now that I've actually done a little reading up on the matter, DoggRom sounds better than going stock.

If it isn't a huge pain in the ass, could someone consolidate what I actually need to do from rooted .532 to get to a rooted DoggROM?

And also - should I be going the C6806 4.4 or 4.5?

I am confused by the whole half-root and then full-root thing that [MENTION=4591949]IchiGoQc[/MENTION] went through - just want to go through this process once and have a rooted version of the best Dogg Rom - and CWM would be nice too if that's part of the parcel.

---------- Post added 13th January 2014 at 12:12 AM ---------- Previous post was 12th January 2014 at 11:49 PM ----------

And what did you do the second time around that was different from [MENTION=3534362]blueether[/MENTION]'s list of steps that originally got you no boot?
[Sony Xperia Z Ultra] jutley:
If i do this on C6833 will i loose 4g
[Sony Xperia Z Ultra] lemmon:
Yes It works !!!!!!!!!!!!!!!!!!!!!!! THANKSSSSSSSSSSSSSSSSSSSSSSSSSS

My only concern is to know if I still have 4G

Do you know if there is any way to check it without being connected to a 4G network. I do not have access to 4G networks in my area

Thanks
[Sony Xperia Z Ultra] jackie099:
u shoud get 4g. its based on us retail version. check network option in settings if there is LTE
[Sony Xperia Z Ultra] hassanmahmood:
Still hoping someone will put up a step by step fully working process for Dogg ROM 4.5/4.4

I'm not accustomed to the flashing process at all - nor have I installed recovery on a phone since back in 2011 - so any assistance would be greatly appreciated. :)

As a refresher, Bell C6806 with locked bootloader - hoping to get to a ROM that still keeps X-Reality and LTE.
[Sony Xperia Z Ultra] IchiGoQc:
I take no credit for this procedure, credit goes to [MENTION=3534362]blueether[/MENTION] :

Flash .532

skip setup

settings

- enable dev settings

- enable usb debuging

Root with this tool: http://xdaforums.com/show....php?t=1886460

- Option 0

Run http://xdaforums.com/show....php?t=2426739 to get recovery

Download DoggRom for C6806

Download ZU-lockeddualrecovery2.7.71-BETA.flashable.zip (7.57MB)

Save both to SD card

Download .290 ftf for the C6806 - Save in flashtool firmware folder

Now comes the tricky bit

Charge phone - I used 40% of the battery while doing this

Reboot to recovery

Wipe Data

Flash DoggRom last version for c6806 from recovery - DON'T REBOOT

Flash ZU-lockeddualrecovery2.7.71-BETA.flashable.zip from recovery

POWER OFF the phone - don't reboot

Start flashtool

Select flash

Select Flashmode

Select the .290 ftf

[Top Box] Uncheck everything

[Middle Box] Check all excludes except bootbundle and kernel, (may need to flash baseband as well if you endup with on imei)

Flash

Reboot phone when done
[Sony Xperia Z Ultra] hassanmahmood:
Thanks a lot.

My question now is, when you did this the first time, you said it would not boot.

What did you do differently the second time?

Or what mistake did you make the first time?

I'll freak if mine doesn't boot once I'm done, lol.

Thanks a lot.
[Sony Xperia Z Ultra] hassanmahmood:
Also - are you able to access Bell apps like Mobile TV? I don't want to risk losing my Mobile TV - but I don't see why the ROM would affect that necessarily.

Have you noticed that if you start the Bell DRM - it request SuperUser for root access?

I think it's very weird that software Bell provides asks for SuperUser access - but yet rooting is technically not allowed.
[Sony Xperia Z Ultra] pTeronaut:
Confirmed on the 40% battery loss during the procedure, but this was the only one that worked for me.

[MENTION=2686480]jackie099[/MENTION], I have an unbranded C6806 and following your procedure using the C6806 flashable and the C6802 stripped ftf, and I am faced with a bootloop during the "plasma effect" boot animation.
[Sony Xperia Z Ultra] vodanhdaisu:
I've followed the instruction but I got bootlop now. I can not turn the phone off at the moment. Please help :(

Mine is C6802
[Sony Xperia Z Ultra] android_myan:
Press power and volume up together to force shutdown.

And follow procedure as per OP.
[Sony Xperia Z Ultra] jackie099:
can u do adb logcat too see whats the error?
[Sony Xperia Z Ultra] hassanmahmood:
[MENTION=4591949]IchiGoQc[/MENTION] Bump bump bump. :P

Or if [MENTION=3534362]blueether[/MENTION] cares to take a stab at it?

Maybe even [MENTION=2686480]jackie099[/MENTION]
[Sony Xperia Z Ultra] pTeronaut:
I managed to get it to boot by following the process that I quoted in my previous post, then flashing your C6806 zip, and then using Flashtool to flash only the kernel & bootbundle.

As I now have a working phone with rooted 290, I don't feel like going through the process again, however, my situation does lead me to think that it was due to something like:

There's a difference between the c6802 & c6806 kernel & bootbundles which make them incompatible with ROMs created for the other.

or that your C6806 rom is missing something that is in the dogg rom, and is not removed when flashing your pre-rooted ROM.

Either way, I have 290 stock rom with root on a locked bootloader, thanks to you for the zip, and blueether for the route to get it to work. :)
[Sony Xperia Z Ultra] Paulcook:
Confirmation please?

Jackie099, can you please confirm which method I should use (on NON Bell, unbranded C6806) to properly implement your file mentioned above? I apologize in advance for the super redundant question, the thread has gotten a little confusing and I just want to do this right the first time. Other than the file already mentioned, what are the other files that this method is dependent on? And again I apologize for any redundancy, but this will still allow for use of LTE and the Xreality engine, correct?

Hopefully I'm not alone in being a tad overwhelmed with all the information in the thread and I'm sure that some concise directions for the C6806 would be appreciated by many. :D

Thank you for all of your hard work and dedication to ZU Development and not to mention, all of us requiring your assistance in this thread.

Regards,
[Sony Xperia Z Ultra] crookx:
Will this work on a 4.3 bell xperia z ultra?
[Sony Xperia Z Ultra] z87365968:
thanks a lot！
[Sony Xperia Z Ultra] pTeronaut:
It should do.

The process that I used for my unbranded C6806 is this:

Download Jackie099's C6806 pre-rooted flashable zip.

Download latest DoggROM zip.

Place zips in external SDcard.

Download FTFs for 290 & 532

Downgrade (Use Flashtool and a .532 FTF for a C6806) YOU WILL LOSE YOUR IMEI, IT WILL RETURN WHEN A 290 ROM IS PRESENT.

Root using RootkitXperia

Install DualRecovery

Reboot into Recovery. (I used TWRP)

Flash DoggROM (4.5)

REBOOT INTO FLASHMODE

Using Flashtool, flash 290 FTF with all options in the wipe section UNCHECKED, and excluding EVERYTHING EXCEPT BOOTBUNDLEand KERNEL.

REBOOT.

Re-install DualRecovery

Reboot into Recovery

Dirty Flash (no wipe) Jackie099's zip.

REBOOT INTO FLASHMODE

Using Flashtool, flash 290 FTF with all options in the wipe section UNCHECKED, and excluding EVERYTHING EXCEPT BOOTBUNDLEand KERNEL.

REBOOT.

In retrospect, lines 10 through 14 might have been unnecessary.
[Sony Xperia Z Ultra] vodanhdaisu:
Thank you for your tip. I've followed then re-flashed successfully :)
[Sony Xperia Z Ultra] crookx:
Do i need to have a unlocked bootloader?
[Sony Xperia Z Ultra] blueether:
The above is almost a copy of what I tested as working on a locked bootloader to get DoggRom running. See post #34 for my tested and working instructions, but much the same as above.
[Sony Xperia Z Ultra] crookx:
Thanks! sorry i should of read before posting lol ill give it a shot tomorrow
[Sony Xperia Z Ultra] blueether:
if it all goes pete tong then just flash a ftf and start again

Have a fully charged phone and use the latest flashtool
[Sony Xperia Z Ultra] hassanmahmood:
I think I'm going to try your method tomorrow - was waiting for a reply to see why he had a boot issue the first time around, but I don't think he's going to reply.

Should I use doggrom 4.5 or 4.4?
[Sony Xperia Z Ultra] Rox598:
Hey people I just want to make sure i have the procedure right before i try it. i'm not new to rooting/CWM but this phone seems like a task to say the least lol

I have a C6833 on .290 4.3

the guide on page 1 says to make a backup but I can't due to no recovery cause my bootloader is locked. i mainly want root first to get those DRM keys backed up before I do anything

how do i flash things with no recovery? (step 5) :S probably being stupid and not reading it properly knowing me -_-

so put C6833_14.2.A.0.290.jackie099.flashable.zip on the storage and the C6833_14.2.A.0.290_Stripped.ftf in the flashtool firmware folder which i've done already but then to prevent bootloops it says ti flash that other FTF that's not for my phone? seems a,lot of work just for temporary root to get my DRM keys lol
[Sony Xperia Z Ultra] blueether:
I would read the sticky about getting the phone ready for flashing thread, and the TA one

You are going to first downgrade to .532 and root that so you can then back up the TA partition

After you have a backup of the locked TA then you can unlock the bootloader, if you can unlock the bootloader then I would follow the guide in the thread I mentioned above as it is less work than this thread - if you cant unlock the BL you have to use this method.
[Sony Xperia Z Ultra] Rox598:
yeah I have been reading them just not sure yet as to what im exactly to do. i tried downgrading to 532 but lost my IMEI suppose i could root that and get the TA partition then just flash the FTF file of 290 and unlock the bootloader from there. should work shouldn't it?
[Sony Xperia Z Ultra] jpeps:
.290 a lte. Version. For c6833
[Sony Xperia Z Ultra] techpal:
Ya that should work.But you have to root .290 again.
[Sony Xperia Z Ultra] Rox598:
trying it now but that root program listed in the thread isn't working :( i don't mind having to root 290 again as i'll be able to unlock the bootloader after getting the keys

EDIT: finally managed to get it sorted! TA partition backed up now to unlock this sodding bootloader
[Sony Xperia Z Ultra] hassanmahmood:
I know how to root and get recovery, I just don't know what exact steps to follow after that to have a fully functioning, rooted 290 without risking a boot loop or the device not booting.

I don't have a backup device to use If I get stuck somewhere, so I want to be as sure as possible the method will work completely.

Thanks so much.
[Sony Xperia Z Ultra] pTeronaut:
It is, I quoted another member's procedure which I paraphrased in my most recent post here, which thanked credited you, and I thanked you in another post which I made in response to Jackie099.

---------- Post added at 03:54 PM ---------- Previous post was at 03:48 PM ----------

Blueether's method that I posted earlier works, and did twice. Trust in @blueether for this.

Jackie099's C6806 ROM will not boot unless it is installed over the top of a DoggROM (I used 4.5, and cannot say whether 4.4 will or will not work for this.), and then flashing the Bootbundle and Kernel from a 290 ftf.

Also, once you are up and running on rooted 290, and you re-install a recovery, (again, I used TWRP) you will be able to restore from a 290 backup without messing with flashtool to restore the kernel and bootbundle even if you have downgraded.
[Sony Xperia Z Ultra] hassanmahmood:
Thanks a lot.

Where do I download the .290 FTF for the C6806?
[Sony Xperia Z Ultra] izzat aizat:
since I already have the official 14.2.A.0.290 firmware from pc companion, what will happened if I just directly root my XZU using VRoot and ignore the other procedure like flash the firmware, and backup etc??

thanks..
[Sony Xperia Z Ultra] hassanmahmood:
VRoot does not work on .290 - it works on .532.
[Sony Xperia Z Ultra] izzat aizat:
owhh...I see. I thought that VRoot has update to work on. 290.. mean, is this the only way to root XZU. 290 without unlocking the bootloader??
[Sony Xperia Z Ultra] blueether:
That may have come out wrong, as I know that you thanked/credited me earlier. Maybe I should have said "..should work as it is more or less what I tested earlier in the thread..."

Anyway this is OT, and I'm happy to help where I can

Good to see that you are making progress, anything above 14.1.B.1.532 is un-rootable via exploits as of now so we have to work our way up with recoveries and flashing pre-rooted roms or have unlocked BL and then root via flashing SuperSU.zip etc

[MENTION=5672599]izzat aizat[/MENTION] and [MENTION=4418141]hassanmahmood[/MENTION] DONT USE VROOT.

[MENTION=5672599]izzat aizat[/MENTION] You are posting in a thread for gaining root on a locked BL on .290. Follow either the OP of my instructions depending on where you want to end up - Stock or modified Stock
[Sony Xperia Z Ultra] izzat aizat:
okay..i'll not use VRoot.. I want to root my XZU which currently hv. 290 official from pcc with locked BL.. and I want my stock. 290 firmware.. can I gain it??

sorry for asking such of question..

thanks for answer.
[Sony Xperia Z Ultra] blueether:
I have edited post #34 in light of the continuing bricked Z1

New instructions look like this:
[Sony Xperia Z Ultra] hassanmahmood:
After reading the post you've referred to and the continuing brick issues I'm quite scared to try.

I completed downloading all the files I need about two hours ago and was waiting for 100% battery to start...

Not sure if it's worth it anymore.
[Sony Xperia Z Ultra] blueether:
I have flashed my phone up and down dozens of times last week and this testing a few things, locked BL and not, often from below 70% charge, and not always flashing all the bits I edited - and haven't had a problem other than windows playing up one day.

Of course YMMV, and I place no guarantees on what I have written. I edited it to be on the safe side - I think we have only seen one dead Ultra from flashing FTFs
[Sony Xperia Z Ultra] hassanmahmood:
What would the advantage have been to the original method over the additional flashing of the new method? Just out of curiosity.

What is the major difference between the additional check marks?
[Sony Xperia Z Ultra] blueether:
On the Z1 thread it is hypothesised that there is a conflict somewhere in the partitions that aren't flashed from a rom .zip

I think that step 18 may be needed again with the flash of bootbundle, not sure though.

EDIT You will have the tick beside System as that is what we are excluding
[Sony Xperia Z Ultra] hassanmahmood:
I understand why it is suggested we do it now, I'm just wondering why people weren't doing to begin with?
[Sony Xperia Z Ultra] jackie099:
Sorry for replying late. Now you can check later posts in this thread. [MENTION=4663180]pTeronaut[/MENTION] figures out the way for C6806. And yes, it keeps LTE and Xreality engine, dont worry.
[Sony Xperia Z Ultra] hassanmahmood:
What do you recommend regarding what to keep checked and what to keep unchecked keeping the Xperia Z1 hard bricking issue in mind [MENTION=2686480]jackie099[/MENTION]?

Everything checked except system?
[Sony Xperia Z Ultra] jackie099:
i dont know what caused issue yet. some used previous version of flashtool, but some say they got bricked by using the earliest one. so i dont recommand flash 4.3 by flashtool.
[Sony Xperia Z Ultra] hassanmahmood:
So I shouldn't root 4.3 with a locked bootloader at this point in your opinion?
[Sony Xperia Z Ultra] hassanmahmood:
I wonder if a couple of people ended up bricking their ZU's and that's why they are no longer replying to this thread...
[Sony Xperia Z Ultra] Nicotine+:
Too much Headache to Root then Keep Root.
[Sony Xperia Z Ultra] blueether:
That would depend on how highly you value root
