[Q] Generic vs Branded rom - Xperia Z1 Q&A, Help & Troubleshooting

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!

[Q] Clarifying question about 4.3 root.

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.

Rooting .290 JB 4.3

Hello,
Coming from a Galaxy S2 flashing and rooting is not new to me but for me there are some questions for the Xperia Z1.
When i bought the Z1 it was on 4.2.2, and offcourse i wanted root the same day
After trying numerous times with Vroot i gave up.
After some more reading i read that i had to downgrade and then flash an older version, then root and flash teh correct version and so on.....(cant find the correct topics anymore )
After doing that my phone wasnt working properly and i connected with PC Companion and it gave me the update to .290 JB 4.3 and everything was fine except foor root.
Did some more reading and found the solution,
Now I'm reading that if you are on .290 4.3JB that root isnt possible(correct me if im wrong).
I want to share how i did it because for me it went very easy.The hardest part was getting the drivers installed correctly hhaha
First i unlocked the bootloader and then i flashed a CWM with root and recovery.
I followed the steps provided on this links.

http://techbeasts.com/2013/12/19/in...ng-latest-14-2-0-a-290-firmware-how-to-guide/
Al of this went so easy that i'm startin to wonder if its me who did it wrong and dont understand it or if you didnt know about it,
The only thing i forgot was a TA backup :angel:
to MODS....if its in the wrong section please replace it.
Actually it is the official way. Unlock -> CWM -> Root with CWM (Notification)
Rooting 4.3 isn't impossible, but morr difficult than on earlier versions. Google wanted to improve the security of android. Most of the ways which "make" the opportunity of rooting are malware-ways too.
You don't need to backup your TA partition with .290 and above, because the camera will work after the BL unlock.
The big question is if root for unlocked boot loaders will ever be available for 4.3! I really doubt it.

You mean Locked Bootloader, i think?
Question about CWM, does it function the same as it did with my S2? So, back-up and restore with CWM?

I have heard from @shem2409 that a partial root on LB for 290 (4.3) is possible, but I have not figured out how to do it yet. I think you can pull it off with the insecure ramdisk hack, but to install that, you need to install XZDualRecovery; to install XZDR, you need to be rooted; it's only possible to root 534 LB and when upgrading to 290 root is lost. So, it seems to be a chicken-and-egg problem to me at the moment. I think I must be missing something.

That's why I do not rooted mine phone yet. Partial root is not worth to do, full root is what we really need but still under testing and also Unlocked Bootloader is needed. Unlock bootloader we lose the DRM keys which we need if one day we want go back to stock and not lose warranty but to do that we have to Buckup TA. To Backup TA we need root, but I updated to 4.3 and I can't. It's to early to fully rooting 4.3. We have to wait. Developers are working on that and I hope a full root come without unlock bootloader. I hope so.

If you want to backup TA now, you can - flash back to any 534 FTF, root, make your backup, then upgrade back to 290.

This is what I don't want to do. Unlocking Bootloader on 4.3 will also compromise few features like Bionz and X-Reality. I don't think I really need them but for me will be good enough to have Full Root with Locked Bootlader and Apps to SD. I don't ask to much, so I wait.

You just took those words from my fingers. The wise way here is waiting and cheering developers to figure out how things work with Z1, 4.3 just came a few weeks ago and (hopefully) we will get 4.4 soon, so for that time you'll have to do that trickery again to keep your phones rooted.

I mistakenly took the .290 update as well and I'm now looking for a way out. This whole backing up the TA thing worries me because I'm afraid I'll lose those DRM keys and bravia etc..... Are you saying that I will be fine and all the keys will be intact if I follow this guide?
Is it possible to downgrade the firmware instead?
What would you suggest?
Thanks

Ok, so here is a little clarification
You need to downgrade to .534, root, install recovery and then flash a prerooted .290 rom from (http://forum.xda-developers.com/showthread.php?t=2572988) or one of the stock-based custom roms such as monxdified (http://forum.xda-developers.com/showthread.php?t=2463675) if you want a partially rooted, locked bootloader 4.3 firmware on your Z1. There is an instruction on how to install on locked bootloader in the thread.
Rooting on the newest version of Android 4.3.3 isn't impossible on the Xperia Z1, it just takes you more steps than normal to actually get full root access. I have a locked bootloader as well but I was able to get a rooted version of Android 4.3.3, specifically the iHackers 2.0 ROM running Android 4.3.3 with full root access. Here's how I got full root access on the iHackers 2.0 ROM:
1) Download the .ftf file named C6903 14.1.G.1.534 Global 1277-2880_R4A from the compiled FTF thread at this link: http://forum.xda-developers.com/showthread.php?t=2469191
This is a version of the original Stock Rom that the VROOT program will actually work on when trying to ROOT your phone.
2) Flash the ROM you downloaded using Flashtool (steps on how you can go about doing that should be in the Xperia Z1 General forum.) and now, you're ready to root your phone with it.
3) Download, install and run VROOT to root your phone. Again, more information on how to properly root your phone using VROOT can be found in the Xperia Z1 General forum. For me, I just turned on USB Debugging on my Z1, connected my phone to my computer while VROOT was running and clicked the green button until I got root access. It's extremely easy.
4) With Root Access, now you can download and install Dual Recovery for the Xperia Z1 on your phone.
5) Download the latest iHackers 2.0 ROM from the Xperia Z1 Android Development thread and copy it to your phone. This is hands down, the best ROM for the Xperia Z1 right now in terms of battery life. With the latest 4.3 update, I'm able to get over 2 Days worth of battery life on one charge. Battery life is much better on the new iHackers 2.0 ROM running Android 4.3.
6) Download the flashable Locked Dual Recovery for the Xperia Z1 here. http://nut.xperia-files.com/
The file is called XZ-lockeddualrecovery2.7.63-BETA.flashable.zip (8.48MB), download it and copy it to your phone, preferably the same place you copied the iHackers 2.0 ROM. To make things easier for yourself, create a new folder on your phone or SD Card in your phone and name it iHackers. Copy both the iHackers 2.0 ROM and the flashable Locked Dual Recovery.zip file into this folder.
7) With both files now copied to a folder on your phone, you're now ready to go into recovery to flash the iHackers 2.0 ROM. Boot into recovery and once you're there, do a Wipe Data/Factory Reset before Installing the ROM.
The rest of these steps are now taken directly from the iHackers 2.0 download thread on the Xperia Z1 Android Development forum.
8) Install the ROM and THEN Dual Recovery. Don't make the same mistake I did, once the installer is finished, DON'T REBOOT THE DEVICE. Uncheck the "Reboot Device" box and go back to recovery to install the flashable Dual Recovery.zip file that's in the iHackers 2.0 folder.
9) Switch Off Your Phone (Do Not Reboot). Select No to Disable Flash Recovery Confirmation.
10) Install Kernel.ftf for C6903 (.290) or Kernel.ftf for C6902 (.290) with Flashtool to get compatible Kernel and Baseband. To download the kernel.ftf file, go to the original iHackers 2.0 thread to download and flash the kernel using Flashtool. You should be familiar with Flashtool at this point since if you make it to this step, you've already used Flashtool once to flash the .534 baseband version of Android.
11) Reboot and Enjoy. Now you're running the latest version of Android 4.3 on your Xperia Z1 on a Locked Bootloader WITH full Root Access. Sure, it's not the stock version but the iHackers 2.0 version of Android 4.3 is just as good, if not better. This will certainly do until there's a better way to simply root the newest Stock Version of Android 4.3.
I've been looking into unlocking my bootloader to install custom kernels on my Z1 but the battery life and performance on my Z1 with a locked bootloader is already pretty impressive. I can't imagine how good it could be with a custom kernel.

No, if you Unlock Bootloader you will lost the DRM keys permanently with Bionz and X-Reality, even with Android 4.3, if you do not do a backup, but the difference from 4.2 is that your phone will still working properly.

Thanx man. I appreciate the time you took to explain the process step by step. One step very important you forgot to mention, Backup TA, never forget to mention that.

The instructions didn't say to unlock the bootloader, which is the only sure-fire way to lose your TA partition. However, I would agree there's no good reason *not* to back it up anyway. Better safe than sorry!

Sorry, no. In his instructions, UB is not necessary because XZDualRecovery can be installed on LB. The reason skipping the TA backup is okay is because the instructions do not unlock the BL.

[Q] C6906 - Supported ROMs?

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

[Q] Locked bootloader , can i downgrade to root.

i recently bought a bell xperia z1, went on to the sony website to unlock bootloader to find that mine is locked, unlike the international version which has an unlockable bootloader.
ive updated it to see if the updates would unlock the bootloader but alas they did not, now im running :
model c6906
android 4.3
build 14.2.A.0.209
Main question :
Will i be able to downgrade and bypass the bootloader?
ive rooted a S2/Htc HD/ Desire Z in the past im just worrying about bricking my phone that ive had for less then a week.
and all other guides ive seen are for different versions, ive heard of flashing the 6903 stuff but that makes me worry way to much.
so pretty much want to know is it possible to do via downgrade to achieve root or should i just wait till a safer method becomes available.
sony bloatware is annoying
Yes, you can get C6906 Rooted with Locked Bootlader. First you have Read a bit more about it, starting with this thread and also watch the Video Tutorial.
You have to use Flashtool v0.9.15 to downgrade to .534 using Rogers FTF for your model from here.
When you are on 4.2.2 FW .534 Root it with Bin4ry Method, then Install Dualrecovery, SuperSU and Upgrade to your favorite latest Android Pre-Rooted, like KitKat Here or JB 4.3 Here.
Done.
Good Luck!
you sir are the man, followed the video and got root, now to find a rom to use.
edit : went to install a rom + gapps and had to do the whole process over again. right from flashing nuts custom. got stuck in a sony logo boot loop. zz
so attempt #2 with a different rom.
edit 2: was able to update to 4.4 kitkat so now i hope i can update my rom. since i was trying to do a 4.4 rom on the 4.3 firmware ?
edit3: nope stuck on sony logo so went back to nuts again... hrmm well atleast i could upate to 4.4 going to try boot to cwm and see if that works
Before I flashed mine I was reading for weeks, You did in few hours and I think to quickly. If the phone stuck in Boot logo, I think you did something wrong but I don't have the phone with me so I cannot tell.
Now you have to go back to stock, keep pushing Volume UP and Power, 3 vibrations, phone in off, keep pushing volume down and connect to pc in flashmode, flash a Stock FTF for your model from the link I give you. Now you phone should boot. Repeat the process to get Root and be careful.
Remember to Wipe Data, Appslog, Cache, every time you flash a Fresh Installation is recommended.

You should not connect the phone to the PC until the PC prompts you after flashtool has prepared the files for flashing

4.4 will need a 4.4 kernel.

Ok, that is why I saw in Flashtool Disconnect and Connect my device few times but never had a problem. Good to know.
i was able to go back and use flash tool to flash nut's ftf
so im on 4.4 kitkat rooted which is good.
but when i flash any custom rom trough any recovery it boot loops im guessing its because locked bootloader.
so im guessing any rom i want to flash has to have 2 parts. The flashing process in recovery and the flashtool flash firmware for that rom.
unless like you said update my kernal

[Q] Anyone downgraded from 5.0.2. to 4.4.4

Hello, I have upgraded to 5.0.2. via OTA a few days ago. My phone was RetEU .23, and the update notification that 5.0.2. became so annoying, so I decided to give it a shot. Lollipop is a disappointment for me, battery drain issues, lagging all over the menus, slow dialer, the phone was running better with KK installed, so I want to return back to 4.4.4.
Unfortunately there is no clear opinion whether this could be done, some say that when you have 5.0.2. bootloader installed with the OTA, you cannot go back, others say that it is no problem to do so. Really confusing.
Anyone tried to go back to 4.4.4. after getting the OTA? Could you please share how did you do so? Unlocking the bootloader and flashing one of the 4.4.4 stock ROMs from the General Section?

Hello,
i actually switched from 5.0.2 back to KK 4.4.4 from Pizza_dox
when your bootloader is unlocked and you have TWRP installed
follow these instructions
1, go do a factory reset
2, go to advanced wipe and select :dalvik cache/system/data/internal storage/cache
when you did that there is no system on your phone so when you restart you will be going into an endless bootloop.
3, go press install and select the Microkat.zip file from Pizza_Dox
when that is done you have agian kitkat on your device
i think there some other methods but this is how i did it succesfully.
Also dont forget to make a backup because you will lose everything.

Thanks for your comment. I actually plan to go back to the stock 4.4.4. I have a basic idea of bootloader and things but not deep into this and have never done it before. From what I have read , I will have to:
1. First I need to unlock the bootloader, as per the instructions in the Moto website.
2. Then I will need to do a factory reset. (settings-secuirity-factory reset or some other way of doing this?)
3. Download 4.4.4 firmware + script.
4. Start up with Power+VolDown buttons and have bootloader menu on screen
5. Run the downloaded script from its .bat file.
6. Wait for some time for the flashing to end, then have stock 4.4.4
Please correct me if something is wrong or missed.

What i did...
Download the correct kk stock rom
Setup my drivers and mfastboot correctly (simple fast boot works too)
Unlocked bootloader. (Voids warranty coz gives bootloader status 3)
Reboot in bootloader now...
Flash all files of kitkat except gpt.bin and motoboot.bin (they never flash for me lol )
Flash all other files (i typed filenames manually)
Fastboot reboot
Ps - no matter what i do..i have not been able to lock my bootloader once i downgraded from 5.0.2 to 4.4.4
Locking bootloader works well on 5.0.2

well guess im gonna try - but no need to do, as makes no difference except to downgrading.... So best off unlocked
simply use the 4.4.4 link in my signature and pick firmware 2 or B called DSDSALL to go back to 4.4.4 .23 ret(xx)
So, it has been confirmed by several forums that when you have officially received the 5.0.2 OTA download update, you cannot go back to KK.
It has something to do with the new L bootloader. I guess that there is no way of doing this, up to now at least. Don't know if someone has tried and succeeded.
When you have flashed the 5.0.2. OTA however, you can have KK installed back, as most of the users on xda.

Successful downgrade from 5.0.2 to 4.4.4
Dear All,
Pls help me in downgrading from 5.0.2 to 4.4.4 on my XT1068 Dual Sim Indian Version.
I need to know whether we can return to 4.4.4 without unlocking bootloader and is rooting needed.
Pls let me know your experience in a noob friendly way.
TIA... :angel:
