Can I root my Z1 having the 4.3 version without downgrading? If so please tell me. I downgraded yesterday and ended up not having having any signal and my imei was a bunch of zero's.
If you know a fix for the downgrading problem that is fine too, as long as I can root it preferably tonight.
Thank you in advance

Whilst downgrading, you have to downgrade to .257 and then to .534. The problem with disappearing IMEI happens only if you downgrade directly to .534.
If you have an unlockable bootloader you could unlock your bootloader and then flash a custom kernel.
If you are on locked bootloader or would prefer to not unlock the bootloader, the only way is to downgrade all the way to .534, root, install recovery and then prerooted firmware.
Could you walk me through the process of downgrading twice without unlocking the bootloader, thanks.

Thank you for your answer, is there a way to do this if I don't have an SDcard?

I made the mistake of doing this last night and now my phone tells me I have an invalid sim... anyone one know how to solve that?
I solved it by flashing back to my stock rom, the . 290 one.

Many thanks, I'll give that a try once I find a generic UK 290 ftf. Can only find the 534 and 257 at the moment...

So I found this post: http://www.xperiablog.net/2013/04/01/debrand-your-xperia-z-tutorial/ look very nice and I would like to try it out. Then I found this ROM for my own country: http://forum.xda-developers.com/showthread.php?t=2200945
Then I read the thread and saw people saying it would be easy to root it also without having a custom ROM. So i went to the recommenden post for it: http://forum.xda-developers.com/showthread.php?t=1886460
Now I have one question: Does this unlock your bootloader? I want to be sure it doesnt! And when I update my phone again after I rooted it do I need to root again? (with rooting there doesn't come another rom over it in this case, right?)
Thank you for your time!
BTW I have an Sony Xperia Z C6603 branded by T-Mobile
Flashing stock firmwares or custom rom doesn't change bootloader status.
After updating you have to root again.

Ok, thx. So when I use the root guide I actually flash my rom again? Or how does it work?
Sorry but i didn't understand what you mean?
Rooting guide is to root your phone so you can access system files,it's not like changing roms or flashing.

You should really use the search button, there are 100's of threads about this.
http://forum.xda-developers.com/showthread.php?t=2439328
That should help. Good luck.
If the 4.2 you're talking about is 14.2.G.2.257, then it's unrootable. You need to downgrade to 534 and then root, then OTA to 257 and you will keep root.
Can the apps from Z2 be put onto non rooted Z1 at all?
Sent from my C6903 using XDA Premium 4 mobile app
Just a few ones, like the live wallpaper MAY work. You need root to enjoy Z2 apps and many other goodies like the Xposed Framework.
Any more word on these apps working without root?

Just use the FTF provided by NUT in Post #3 here. Then use Bin4ry Method to root, Install SuperSU, XZDualRecovery and update to 4.4 again form http://forum.xda-developers.com/showthread.php?t=2687443.

Yes, dualrecovery you have to have to install 4.4 from .zip file then stripped from Flashtool. It's an easy installation and you will forget even to have it but is really important because you will do a full backup of your System and if something go wrong you can restore it.

I'm not sure to understand but you can root your phone in 4.4.2 too
Also be sure to have the latest Flashtool version.
BTW i'm not agree with augie7107, there is no major problem to downgrade by flashing a FTF file with flashtool.
There is no root method for 4.4.2 without unlocking the boot

Yes but you can flashing a pre rooted rom, that doesn't need to unlock your BL, i'm using the 4.4.2 NUT ROM with locked BL.

Hey guys and girls i've had my Xperia Z C6603 since it came out and I had rooted it since it was realeased to be able to but the other day I went to flash a custom ROM and bricked it. I then used the Sony tool to put the latest OFW on and reset it and then tried many different rooting methods with no luck.
I have the
C6603 on 4.4.2 and the.bootloader is not allowed to be unlocked.
Is it possible to flash a custom ROM and root it? And if so which method will work?
Its on 10.5.A.0.230 build :/
Thanks people.

If you're going to keep posting that, you should also advise people that it requires unlocking the bootloader and therefore invalidates warranty.

Indeed it does require an unlocked bootloader.
In your situation, the only way to gain root is to downgrade to a 4.2.2 firmware, root and flash a prerooted KitKat rom or a custom rom of your preference.

As the post is not in noob section its assumed that the poster is aware that it will invalidate the warranty.

It's the Q&A section. If people knew everything, they wouldn't be asking for assistance here.
Please stop posting incorrect or incomplete information and replying without reading the question properly and I won't need to keep correcting you.
I'm sorry that you appear to be upset, but if you're going to reply to almost every thread here, then you should at least try to provide correct information.

You're correct. There's no way to unlock your bootloader.
Yes, you will need to download a 4.2.2 firmware and flash it using Flashtool. This will probably require that you wipe your data, unfortunately.

Thats perfrctly fine, I had backed up all my data with Helium Premium to Dropbox before I bricked it but now need root to get it all back lol

1. Download a 4.2.2 FTF - Download.
2. Flash it with Flashtool.
3. Install XZDualRecovery using the unrooted method.
4. Install a prerooted KitKat rom, such as this or a custom rom of your choice.
If you need any help with Flashtool, then just ask.

When updating to a new ROM eg, one at 4.4.x do I really need to upgrade up each build version? I looked at the requirements and one requires the next down, and then again and I think I would need to do it like 4 times.
You shouldn't need to, as most custom roms provide everything you need. The zip sometimes contains everything or sometimes you have to use Flashtool to flash a supplied FTF for the kernel and baseband.
If you're unsure, you could ask in the specific thread for the rom.
