My apologies if this is obvious to you all but ive been roaming back n forth over all the threads trying to find the best course of action. I am looking to root my device (c6903) to 4.3 rooted. I am currently running 14.1.G.2.257 I understand that this firmware cant be rooted and i need to downgrade to 14.1.G.534.
Q1 do i then wait once rooted for the OTA update or do i then backup my TA and flash a rooted generic 4.3 using flashtool?
Q2 is it better to just update to 4.3 generic unrooted and wait for this firmware to be rooted which i believe is being worked on. I have noted that my device can unlock the bootloader if this helps?
Thank you for any advice im a bit confused on which course to take

This is for my curiosity and many other users who I know are wondering the same thing, I've searched for this, but can't really find anything that answers it to my satisfaction.
So I'm running 4.3, with build number .290
I want to root my phone, but I know I need to flash .534 back to my phone. As far as I know, THIS will stop my sim being recognised by the phone. Do I then need to ROOT the phone, and then flash .290 again for the sim to work again.
So which .290 flash will I use? Just the normal FTF file for .290?
Thank you, I'm an active contributor to the forum, but I like to be super sure about what I'm doing before I do it, and I gather many other users do. The reason I'm asking in such detail is because my phone was rooted before, I updated (by mistake) to 4.3 and then flashed back to .290 where it stopped my sim working. Took me a few hours to work out how to fix it, as the pccompanion wasn't working for me!
Thank you!

why don't you unlock your 4.3 rom and flash a recovery to root it ? would be easier

If you want to flash the firmware you have, follow this guide from part B to part C, then you will have a ftf copy of your current firmware.
About the root thing, downgrade to .257 then .534 so you don't have the IMEI and signal issues. Then root and OTA to .257 and then, if you get OTA update to .290 go for it, but some people said that you will only get partial root access.
So you will have to either flash a prerooted firmware or unlock bootloader and turn off Sony's RIC and then root the normal way.
To unlock bootloader, just follow the instructions here but don't forget to backup the TA partition using this guide.

Hello,
I have an Xperia Z1 - C6906 with a locked bootloader from Bell Mobility in Canada, I am wondering if there is any ROMs that support this model, and if so is there any caveats that I need to be award of for this model when flashing something that isn't an officially released version.
Regards
I'm using Monxdified 4.2.2 version (not 4.3) on my Bell 6906, no problem at all. Just follow the instructions.

I keep seeing you need to flash the firmware and kernel for your model, that isn't separate/done after flash - you just flash with the official firmware and then exclude it in flashtool?
I don't think its really worth it in my mind. If flashing custom roms, especially kernals is something you want sell your locked z1 c6906 and opt for one directly from Sony.ca which will be fully unlocked. If we can ever get root on locked bl and 4.3 then you can just "trim off the fat" apps with titanium and make it alot lighter running. I'm in the same boat as you with a 6906 from Bell. Was totally unaware of the locked bootloader lockdown before I bought it and I am suffering the consequence now. 6906's are still going for anywhere from $500-550 locally here so I think I am going to put it up for sale.
Anyways, just thought id share my thoughts as I'm in the same situation as you.
Cheers

Yeah, what I did was downloaded .257 Canadian version and after I flashed monxified ROM in recovery I flashed Kernel and Baseband of canadian .257 version in flashtool.

I am currently on .290 unbranded (I flashed it previously), I don't have the option right now of selling or changing phones so I am stuck with the locked boot loader at the moment. I am wanting to flash Pure Stock so I can get rid of all the bloat.
However the instructions state that I need to be on .534 to get root and install recovery. A couple questions - a.) the only 906 version of .534 is branded Rogers - would this cause any issue with my Bell phone. b.) as I am on .290 with a locked boot loader is there any issue with flashing to an older version?

Nope no issues with Rogers .537 at all. I've been flashing that ftf all the time. However, I would suggest staying away from .290 ROMs for now, because my first Xperia Z1 got bricked badly with ihackers 2.0 (.290) ROM. I had to buy a new one until this gets fixed (cant stay without a phone). I'm enjoying .257 ROM (with full root access) at the moment and not looking to jump into Rooted .290 unless I'm %100 it wont brick my device again.
So I've been playing around the last week or so with my 6906, and a 6806....
I've been able to root and install the recovery easy enough on a the generic .534 build that is in the FTF thread. I believe it's the rogers one... So it does seem to pull some of the bell crap out... Putting the twrp backup data back on, gives me some of the apps back, but it doesn't seem quite as bad. At least you can then uninstall it if you don't want it. <G>
However, I've been trying to get up to the .290 builds that Nut has been providing. However, on every attempt I've been getting to a soft brick, when I use the flashtool to put the Kernel and baseband on.... Reflashing the .534 build at that point, gets me up and running again without any issue.
There is a generic 290, and new 132 build for the canadian 6906 that have been posted, but no root.... If you want stock and no mods.....
I haven't tried anything else at this point, since I'm still getting my feet wet.
Hey guys I hate to resurrect this thread but can you point me in the right direction on finding a stock Bell FTF. Even any old ones that I can upgrade to after. I tried a generic CANADA one but for some reason its still show as a US after a flashtool. I need to go back to stock to send my 9606 in for warranty and dont want them to blame the firmware for hardware issues.
Any help would be greatly appreciated
thanks
So.. I was on 14.2.A.1.136 (4.3) stock firmware.. I wanted to root and I had to downgrade to 4.2.2 then root then flashing 14.2.A.0.290 (4.3) firmware.. Thanks to @shem2409 and @[NUT] for this method.
Anyway.. After rooting and flashing and all of that.. I received an OTA update for the stock 14.2.A.1.136 firmware.. And I was really surprised because what I know is that you lose the OTA updates and pc companion updates capabilities after you root your phone.
So my Question is.. If I updated the firmware OTA will I lose thr root? I can't afford to root it again for at least 3 weeks because my laptop is on the maintenance right now ..and I need the root privileges.

Hi
Did the same thing for my phone....however I did not update back to 4.3 via ota but instead downloaded the pre-rooted firmware version for 14.2.A.1.136 pointed out bh someone to me on xda. I'd suggest you do the same as I havent lost root access after finishing this.

is it the same firmware ?? I mean .. is there any differences between the pre-rooted version and the original ?
and I read about that there is a chance of hard brick the phone after doing this .. did you face any similar problem ?
No... I had no issues.... Yeah the same firm ware...
Hi guys this is my first post here so be gentle! I'm trying to get cyanogen mod on my Z1.
I have followed the guides on this forum, my appreciation to all involved here great job!
I downgraded to 4.2.2 from 4.3. I then rooted my the phone. I then unlocked the bootloader.
All went ok. I then downloaded C6903_14.2.A.0.290_1276-0875_Generic UK.ftf and flashed it. The phone then wouldn't turn back on.
So I downloaded C6903 14.1.G.1.534 EE UK 1276-2219_R9A (I'm on EE) and flashed that and I got the phone working again.
I then flashed DoomKernal to get CWM. DoomKernal went fine.
Somewhere along the line I think I got confused and thought DoomKernal would give me CWM and I flashed C6903_14.2.A.0.290_1276-0875_Generic UK.ftf again to upgrade back to 4.3.
Same problem...Phone wouldn't turn on so I repeated the EE branded 4.2.2 flash.
Now DoomKernal seems to be taken off. So my questions are as followed:
Do i need DoomKernal to get CWM?
Do i need to be on 4.4 before I install Cyanogen mod or can I do it straight from 4.2.2 with DoomKernal?
If I'm being a total noob I apologize!
Thanks.

Accidently gave you a thank lol
I actually don't know about branded phone, but I can tell you that your step has gone wrong. You will always lose root
if you flash a sock ftf file.
So you are saying you unlocked bootloader on the 534 rom? Your camera is probably dead now, check it if you can boot.
Unlocking bootloader before getting on 4.3 or 4.4 will result in disabling the camera. You did it now anyway, I can't help you. Maybe flash 4.4 now and see if your camera works again.
Flashing cyanogen is not about root but unlock bootloader, people would recommend you to root first becoz you will be able to do TA back up with root
(TA backup is a way to backup drm key, so you can restore it in the future and restore locked bootloader exclusive feature like X reality and better quality camera. Seems you don't know what I'm talking about and already unlocked the bootloader before you even ever heard about TA. Sorry can't help you to save this part, you may continue anyway)
So on 4.4, you may have to unlock the bootloader again since the bootloader itself maybe relocked itself when you flash a sock ftf file. ( doesn't mean you restored DRM key is back)
So maybe unlock it again and start to flash cm.
Personally I wouldnt recommend a newbie in Android to unlock bl so fast since it's too easy to mess up serious things up and it's not so easy for turning back. Well you started messing them up anyway, continue then
Thanks for the reply.
I did do a TA back up before I unlocked the bootloader....If i restore from this will it get the camera working?
I have tried to flash Cyanogen mod but it fails error 7. It thinks my Z1 is a Togari (Z ultra) which it isnt cant find anything on this!
Ok so, i'll try and get on 4.4...
I have a UK Z1 C6903.
Can I flash to C6903 14.3.A.0.681 Global 1277-2880_R5C (this is 4.4 right?)
OR does it have to be a UK one I cant seem to find a uk 4.4?
So after a bit of stress and the phone getting stuck in bootloop I have installed 4.4.2 using .681 commercial.
I hope it will be smooth sailing now to install cyanogen mod
Oh and the camera works again!

Hello!
I am new to this forum and i have rooted my xperia z1 (c6903) using this guide
I have not unlocked the bootloader yet
However it required me to downgrade to a lower firmware.
I have downgraded the phone and rooted it but now i want to go back to the latest firmware but i want it to still be rooted.
I dont really know what to do.
