Problem rooting Xperia Z1 (KitKat)

Okay .. So I'm running ver. 14.3.A.0.681 on my Z1 and I want to root it .. I heard of a method in which the phone must be downgraded, then rooted, then reupdated again using flashtool .. But every time I try to downgrade I get stuck in a boot loop .. I have managed to fix the boot loop problem by reflashing the 14.3.A.0.681.ftf
Please guys how can I downgrade without having this problem? And does this rooting method work? If not, what should I do?

Hi ralph97,
Here is what I did (although I was on .257 to start with)
1) Flashed C6903 14.1.G.1.534 Generic from here - http://forum.xda-developers.com/showthread.php?t=2469191
2) Install dualrecovery from here - http://forum.xda-developers.com/showthread.php?t=2261606
3) Flash SuperSU (via recovery) from here - http://download.chainfire.eu/282/SuperSU/
4) Update to NUTs .681 from here - http://forum.xda-developers.com/showthread.php?t=2687443
Each time I flashed an ftf, I cleared everything, so I made a backup (I just copied the stuff such as music, photos etc to my pc)
I hope that this helps.
PS - all cradits to helping me to @gregbradley

Alan

If you open the BL there is no need to make all the way back to 534.
You just have to open the BL install a recovery, on the 680 ftf, and then install the supersu.

Yes this is true, but you may want to backup your TA partition before unlocking the bootloader and this needs root, so you have to downgrade to .534 anyway.
So, yes technically you can do this, but I DO NOT advise it.

Well, the first time you do it, probably it shoud be done as you say. :laugh:

i also do that...its work..dont need to downgrade..

I hoped you backed up your TA....
You need root to do it, so it has to be done BEFORE you unlock.

Please remind to People the consequences in doing this! Like the Warranty, after Unlock Bootloader, will be Voided and even before that, like @gregbradley already said, Backup TA to not lose DRM Keys. The short way isn't the best all the time.

You do not reupdate by flashtool.
Only with the recovery.
Damn my thread got locked.

Guys thank you very much, but i went with the safe way and downgraded, then rooted using v root .. but there is still one problem, everytime i try to flash the dual recovery (on cmd), i get:"adb sserver error killing..."
"unable to open daemon"
What should i do??

Sorry if I sound stupid(own a samsung GS2, which was rooted within 10 minutes ), but can I flash a rooted rom(like ihackers for e.g.) after I install dualrecovery instead of flashing SuperSu and than updating to NUTs .681? I can live with jellybean a few more months

You still need to flash SuperSU to get full root, but in step 4 just flash the ROM of your choice.

The process is incorrect.
You can root up to version .254. You can't root .201 or .266. by the method you stated.
To root .201 or .266, you can install one of the customised roms (see android dev section)
Some roms required unlocked bootloader. Others do not. So read the instructions carefully.
I am current on rooted 201 using this ROM:http://forum.xda-developers.com/showthread.php?t=2658043
(version 2.1 - you install v2 then update with v2.1 on top).
You will still need to downgrade to older version so that you can get root and recoveries before you can install the above rom
Good luck

Not sure what 284 is (probably global ftf of version 257), but the last version before 4.3 was 254. You can try though.
Answer to your last question:
As stated: YOU CANNOT ROOT 4.3 (266 OR 201) with doomlord's exploit- PERIOD.
Once you flash the 4.3 kernel, your phone will go into a bootloop.
You can only use doomlord's exploit for version 257 up to 254.

Hi, i already with 4.3.3 and roted,but when i turn on the Phone not apears the ligth of recovery :s. is a bug or i need to install aggain??

isn't there any way to root .201 without downgrading and without losing drm keys?

You only lose DRM keys if you unlock the bootloader, not through rooting.
The downgrade to older 4.1.2 will not cause the loss of the keys...

You didn't say how you rooted your device.
If it is through other roms, these roms would usually include a set of recoveries.
I have not tried (because I got both root and recoveries through customised roms for 201), but you can try dssmex's files to install your recovery. http://forum.xda-developers.com/showthread.php?t=2649923

O.k. Rooted my phone by downgrading to .254. If I use Flash tool to install .266 tft will that destroy the root?
EDIT: NVM answered the question myself.

[Q] Issues flashing roms. "Failed"

Hi there.
I have a UNLOCKED bootloader.
I have downgraded my firmware using Flashtool and enabled USB debugging, used the .bat to install the recovery and used the Chinese windows app to gain root, using an app from the Google Play market I checked and it said I had root.
The phone after installation of recovery rebooted into recovery fine and I flashed the flashable recovery as said in the guides. if I install any rom it will say it's checking the MD5 (or whatever it is) and then displayed "Failed", which will then cause the phone to go into a boot loop and lose root, it's really bugging me.
Any pointers on what may be going wrong?
Thank you

This is the Worst way I ever saw here to gain Root and you really messing with your phone.
1- If you unlocked your bootloader, why are you downgrading?
2- Why do you used a Chinese app to gain Root, which it is? What is the name of that App?
3- Why you dodn't read the instruction of how to gain root? (it's a fact you didn't as you explained wrong steps)
Flash Stock FTF vie Flashtool in Flashmode, then Flash an Advanced Kernel with recovery implemented via Flashtool in Flashmode, then boot into recovery and install a Pre-Rooted latest NUT Rom or any Custom one, follow the instruction to do that.
Done.

Sorry I was reading the sticky and following that in the General, which suggested using the Chinese app. Please would you suggest me the advanced kernel with recovery? Many thanks

Flash first .136 FW to clean up and wipe everything, then install this HERE, then you can upgrade to any rom you want.
---------- Post added at 11:35 PM ---------- Previous post was at 11:18 PM ----------
..the kernel i posted actually have to be installed via fastboot, you have to install adb drivers first, boot in fastboot and install the Kernel...

No, he should flash a 757 FTF, then flash advanced stock kernel or doom kernel via Fastboot. That's it, you have root.

Actually there is instructions that saying that Kernel, which I posted, working on .136 only, so I am not sure if will be fine on .757.
If he will use different kernel then yes, he can flash .757 FW and a Doom Kernel, done.

Agreed with this post from @gregbradley, this is a much better way of carrying this out Kudos (Y)

OTA will always fail when you're rooted, as signature checks will fail. You need to flash a pre-rooted 157 after wiping system and caches (not data).

Install a non-rooted, fresh copy of 157. Close Sony Updater tool(s).
Flash the 108 kernel using Flashtool. Close Flashtool.
Root using XperiaRoot. Close XperiaRoot.
Flash the 157 kernel using Flashtool. Close Flashtool.
Install XZDR Dual Recovery, and use TWRP from now on. CWM is old and should be killed with fire.
Send me $50 and a large pepperoni pizza.
Files are available here.

hi all friends how to install cwm or twrp or philz on sony z1 c6903 runing 5.1.1???whit out unlocking bootloader
its for my brother i haven't z1 so i dont know how to install it.

OK you can install recovery without unlocking bootloader by using Nut Recovery for locked bootloaders
But you must be rooted with SuperSu not kingroot
If you are not rooted or rooted with kingroot u can use Thread to root or replace king user with supersu

Are you sure your custom recovery is installed? What did you do to install and enter it?
