Hello.
I searched some but i could not find the answers so hopefully i can get them in this post.
Well what i was wondering about is: I have unlocked my bootloader the official way. Let´s say i wanna relock it again, flashing a stock kernel.sin and using flashtool to relock it.
What method is then used to Unlock it again if you would wanna do that ? And i dont want guesses here i want solid facts of what works and not.

I just use FlashTool to unlock and relock after officially unlocking it the Sony way. I haven't experienced anything odd or harmful doing it this way. Seems to be nice and safe. Currently my Z1 is rooted, stock kernel, dual recovery installed and bootloader locked and it's working great!
dual `?

Dual installer recovery ?
Im kinda newb but wont root go away if you apply stock kernel ? what kernel are you using. had a hard time finding stock ones. Unless you mean to just extract from a ftf file.

On Locked Bootloader you can use Custom Roms with Stock Kernels as it is the only one kernel what you can use on Locked Bootlader.

Ye but do you extract stock kernels from the ftf´s available or will it just wipe the kernel if you flash a ftf from the big ftf list ?
Before flashing JUST the kernel from the Global Generic FTF posted here I flashed (in recovery from ADV Stock Kernel) NUT's dual recovery for Z1 from here: http://nut.xperia-files.com/
Then after stock kernel flashed I relocked bootloader in FlashTool and still have access to recovery if I need it (say I lose root) and can always reflash Update SuperSU from recovery and booyah!! Root restored though I never lost root but if I do I can get it back super easy!!

I don't know what exactly you mean. If you want to keep your kernel you can flash any Stock FTF and exclude Kernel in Flashtool, that will wipe the system but the kernel will remain the one you have, it's called Dirty Installation.
If you have Custom Rom with Custom Kernel and you want, for example, relock your bootloader then with Flashtool flash the Stock Kernel only, how? Just use any Stock FTF, put it in Flashtool folder, select the FTF and exclude everything and leave just kernel clicked, it will flash just the Stock Kernel from the whole Stock FTF.
Done.
Xperia ZR • Pre-Rooted Stock 10.5.A.0.230
Hi everyone!
Today, the first 4.4 build of Sony for the Xperia ZR rolled out.
So, I've use DIY Guide by @[NUT] to build an pre-rooted version for you. (Me, I'll go back on custom ROM after testing that for you. ^^)
It's available for LB and UB.
Let's go!
Features :
Based on the firmware 10.5.A.0.230 (4.4.2) (Taiwan location for C5502, Nordic location for C5503)
Pre-Rooted
Built-in Dual Recovery @[NUT] 's"XZDR"
Needed files :
For both (C5502/03) :
UPDATE-SuperSU-v1.94.zip (→ Paste it on sdcard)
ZR-lockeddualrecovery2.7.124-BETA.flashable.zip (→ Paste it on sdcard as well)
For C5502 (3G) :
Xperia ZR C5502 • Pre-Rooted 10.5.A.0.230 by Thibou.zip (→ Place on sdcard)
C5502_10.5.A.0.230_Stripped.ftf
For C5503 (4G/LTE) :
Xperia ZR C5503 • Pre-Rooted 10.5.A.0.230 by Thibou.zip (→ Place on sdcard)
C5503_10.5.A.0.230_Stripped.ftf
Installation :
If you coming from on 4.3 :
Flash 4.2.2 FTF or 4.1.2 FTF
Root your firmware with VRoot/Kingo etc (for 4.2.2) or with Doomlord's one (for 4.1.2)
Install Recovery
Boot to Recovery
Wipe cache partition, wipe Dalvik cache and wipe Data/Factory reset
Flash Pre-Rooted Rom .zip file from Recovery
Flash "UPDATE-SuperSU-v1.94.zip" from Recovery
Flash "ZR-lockeddualrecovery2.7.124-BETA.flashable.zip" from Recovery
Switch off your phone
Flash Stripped FTF with flashtool
Reboot your phone
First boot will take longer than usual boot.
You're done!
If you have LB with 4.2/4.3 and Recovery or UB :
Go to Recovery
Wipe cache partition, wipe Dalvik cache and wipe Data/Factory reset
Flash Pre-Rooted Rom .zip file from Recovery
Flash "UPDATE-SuperSU-v1.94.zip" from Recovery
Flash "ZR-lockeddualrecovery2.7.124-BETA.flashable.zip" from Recovery
Switch off your phone
Flash Stripped FTF with flashtool
Reboot your phone
First boot will take longer than usual boot.
You're done!
If you have trouble with recovery, delete the folder "XZDualRecovery" and reboot to recovery with the app "NDR Utils".
Please... Backup your data before starting.
And don't try dirty install. Make clean install to avoid lot of bugs. So, make all wipes.

1.yes, it is rooted after flashing this.
2. If you mean your phone may become a brick, I can say that is very very unlikely. In case things go wrong, u should still be able to recover it to original condition. So the risk is really really small.
3.To do this, you must have your phone's bootloader unlocked, and that means a good bye to your warranty, of course. But if u use Backup TA (search in this forum) and a recovery tool, u can recover your phone and even relock the bootloader and warranty comes back
4. Bravia Engine remains with you. This is an update, it can only be better than before, no way disappeared.
5. Honestly I don't know. But since Folder Mount supports 4.4, it should work here as well.
6. You should check your model if it is C5502 or C5503. If it is 5502, then no problem. If 5503 (in other words Egypt has LTE) I think you can't no longer use LTE in that case you should wait for someone making a prerooted version for C5503.

Then you have to wait, or learn to DIY. Because it's harder to make it prerooted in locked bootloader, and also not many people out there worry about unlocking, so
LB versions always come later than their UB counterparts.

Ok cool so how do i flash it do i need a custom recovery like samsung or what?
another question
is there any thing bad will happen if i unlocked bootloader ?? and btw iam c5502
Ok guys, I had connection problems. It's uploading now.
I've build the pre-rooted version for C5003 too.
Concerning locked bootloader (LB), actually it's possible to install this pre-rooted version but it's complex. I'll tell you what to do for LB.
As I said in OP, you will have the links today or tomorrow. Be a little bit patient. It's a question of hours. I study during the day...
thanks

ok and thx for pre-rooting
My C5503 is locked and I installed a pre rooted 4.3. I downgraded to 4.1.2, rooted with doomlord rooting kit, installed dual recovery, then flash a pre rooted 4.3.
Will test the 4.4 once it is uploaded

BOOTLOADER: UNLOCKED
hi guys, need help here
since there is now a safe way to root 4.4 on Xperia Z, i am thinking on updating it and give it a try
however, due to the unlocked bootloader, i can no update the firmware ofcoz
so i've been doing a bit of research, but at the moment very confused
just hope if anyone can point me the right direction plz
from my understanding, using the newest Flashtool, i can relock the bootloader using this method
http://forum.xda-developers.com/xpe...bootloader-t2153261/post38124976#post38124976
how ever, DooMLoRD also states that
1. DO NOT USE ANY FTF TO RELOCK BOOTLOADER! THOSE OLD FTFs DO NOT WORK FOR THE 2013 DEVICES!!!
2. be on pure stock kernel (flash only the kernel.sin using flashtool)
i am guessing what DooMLoRD is saying is that
all i have to do is simply flash the KERNEL.ELF file, and nothing else
before i start with the relocking procedure?
with in the post http://forum.xda-developers.com/xperia-z/help/flash-stock-kernel-relock-bootloader-t2748769
Ben Ling provided a download link for the KERNEL.ELF

Hello folks!
I know my question has been repeated thousand times here.
I have tried to understand by myself and read as many threads as i can but to save some time and data bandwidth i want to know the shotest and safest procedure to downgrade my z1 c6902 from lollipop 14.5.A.0.270 locked bootloader to kitkat and try some custom kk roms. I have already rooted lolllipop using kingroot app. Recovery is not installed yet.
Do i have to flash kk ftf before doing anything?
Or i can directly flash dualrecovery and start flashing cm roms?
Also want to confirm wheter i have unlocked my bootloader to use cm based kk roms?

since ur already rooted ur lolli better to run the executable NUT's dual recovery and then back up the system to ur external.
answer to 1st question, yes u have to flash KK ftf if u want to downgrade.
u can flash directly the nut's dual recovery and flash custom rom like rockz1 and dstrikers rom
3rd bootloader is required to unlock if and only if u wanted a modified kernel like trinity..it depends on custom rom's requirement..better read it
1. hi all i wanted to ask for ur guidance/procedure on how to recover from bootloop if recoveries aren't functional after u've flashed a custom ROM.
2. what will happen if we flash kernel to LOCKED BL?
plz exclude flashing the stock FTF file, i need other options aside from reflashing.. i knew it already.

1. You are sure you did it this way as said under point 2?
2. It depends.
As far as I know - most base of all base rules is to stick to proper kernel.
Locked BL requires kernel for locked bootloaders.
All parts of ROM has to be consistent together. system, boot, kernel ...
Either for locked or for unlocked BL. Mixing stock and custom ROM parts is very unhealthy.
I think you need to know if the device enters in flashmode, next would be flash a new stock rom ftf with flashtool.
If the steps are OK you should have your device fixed, and have the bad xperience mixing lb ub Kerns could be....
Hope 2 have helpd you
