This is my understanding too. Bear in mind that as soon as official updates are released a developer here will make it available on xda. This means you often get updates before you would normally (because they are rolled out at different times depending on carrier and region).

also i saw lots of mods need deodexed rom, can i deodex my stock rom or do i have to flash another?
Once you install CWM, you can deodex your stock firmware without any problem :good:
No need to flash another ROM to do that.

Odexed roms work faster than deodexed. If you don't plan to modify your rom don't deodex it. Though there are many mods for odexed roms too.

The SP is pretty powerful I think it won't make day to day difference.

I'm on 257 firmware.
How can I update to 284?

The update is only for c5302 Sp models.... If you update your c5303 modern with .284 you will lose 4g connectivity but not much else.

You didn't do anything wrong, but currently Android 4.3 cant be rooted. if you want root, you have to flash 257 then 534 then root and OTA update to 257. and if you get OTA to the 290 android 4.3 you might keep root.
Do you know when root will be available for 4.3?

You can root, but you need to flash custom boot.img first. Just follow steps on http://forum.xda-developers.com/showthread.php?t=2573921

One of the 1st rules in XDA: Don't ask for ETAs
You must follow the threads and see, if one dev find a solution to root locked bootloader for 4.3. But take a look in the Xperia Z1 Android Development section. Or this thread, there a lot of hints and howtos for root.
Sorry I'm new! thanks for the tip!!

[Q] Rooting xperia sp

Hey guys,
I know i've asked this question before.
But now i really want a serous answer,guys i want to root "12.1.A.1.201",
Without downgrading,losing DRM keys and/or flashing custom ROM.
I want to be able to revert my phone to stock to get warranty when needed easily.
So i request @DooMLoRD to update easy rooting tool-kit to 4.3.
Or you guys suggest to in this matter.
Thank you in advance.
yeah DooM, please update easy rooting toolkit
I don't think that's gonna happen, because there isn't an exploit for .266
yes i have same request please @DooMLoRD

what is going on is this a joke ?
i asked a simple quesiton and i saw these replies ?
my question is my boot loader locked ?
okay from the first comment i can see there is no root for this version yet
but i can downgrade this version right and then root this device from jelly bean ?
If your on nc2 there is no root and no going back to jellybean. Bootloaders are locked. So you pretty much stuck on the official kitkat like the rest of us. Even though not for long. I read somewhere that an exploit was found that will permanently unlock the bootloader but it won't be available till August some time. So we need to be patient.

[Q] Able to Root anymore?

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.

As far as I was aware I couldnt unlock my bootloader if it states it wasnt allowed, and do I just need to use the Flashtool program to install a previous firmware? Im not up to date on rooting as left my mobile the same since I girst

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.
