[Q] questions about ...unlock bootloader, root, update rom

hello, I am a software developer but not Android, I'm sorry I can not give no contribution for now. I have a razr_i (Retail GB) with stock ICS 4.0.4 and I'm pretty good especially with the consumption of battery. I could install Jelly Been with OTA. but first I want to be sure I can, however, at a later time to install a cooked rom any optimized. I have read several threads interesting of which I can do after you've installed the root Been jelly with OTA. http://forum.xda-developers.com/showthread.php?t=2123369
what is the procedure? example install jelly stock then root the phone. Then later I want to install a cooked rom. and to do this I have to unlock the bootloader and install a better recovery CWM or TWRP.
I am not clear what are all the steps after installing Jelly Been stock or whether they should take some steps to ICS Stock.

If you are still on Ics i reccomend you to first unlock the bootloadet for prevend future bricks
Second, i prefer upgrade to jellybean with the homemade versions, cause are fully stock but are rooted
And after that, instal cwm or twrp

Hit thanks if i help you or you like my style

sequence:
1) first I have to unblock the bootloader (ICS)
A) then install a new CWM recovery or TWRP (I prefer the latter)
B) then the root
2) Install jelly Been stock initially or later if possible a cooked rom JB
the second (2) step is not clear how I implement it. you can always do the upgrade with OTA after the first step without any problems or special measures are required, and then the fastboot must be compatible with jelly Been stock? there is something not clear to me. thank you for your answer. the devil is in the details

Well the steps are correct but first install the ota update before root, cause if you root on Ics its gonna lose it when you upgrade so
1- Unlock bootloader
2-Install ota update before cwm (cause the ota update needs the original recovery)
A- You are now on stock jb with unlocked bootloader
3- Install Cwm or twrp
4- Root it whit the root pack for jb on development section

[Q] Downgrading on locked bootloader

Hi guys!
I have searched the forum and I DO have got a lot of answers. But still I want to get some things clear before I go on.
I just got myself an Xperia Z. It was already updated to 4.3 .569. The phone has a locked bootloader and I found out that it CAN´T be unlocked. So there I´m stuck.
I was first thinking about following this guide: http://forum.xda-developers.com/showthread.php?t=2590088
But then I got some more questions.
If I downgrade according to that guide... since I get a custom recovery, can I flash any custom ROM that is made for locked bootloader? Do I even have to use the 4.3 .569 used in the thread above or can I just downgrade and root then choose the ROM to my liking?
Thanx for all your help!

Downgrading
Dear friend:
1-the easy way::laugh:
2-Flash 4.2.2 with flash tool
3-Root on locked boot loader
4- Install Dual Recovery follow
5- Install 4.3/4.2 Pre-rooted or any other rom of your choice.

Once you've downgraded, rooted and have a custom recovery, you can use any rom you like, as long as it's a stock based rom for locked bootloaders.
You cannot flash anything based on CM/PAC/AOSP/AOKP etc as they require a custom kernel and therefore an unlocked bootloader.

[help] need infos on latest rom and latest root method

hello I am an old Z user , but it got stolen 6month ago...
I just got a new one, I'm not a noob but I'm lost on what is the latest rom to install and the proper way to root it as I'm sure old methods aren't working anymore...
from what I roughly understood, you need to unlock the bootloader now?
if yes I would need help on that!
(I heard about some "framework" stuff to install as well)
thanks for helping !

latest ROM is 4.3 - build number 10.4.1.B.0.101
You only need an unlocked bootloader if you want custom ROMS such as CM, PAC etc with custom kernels. Cant flash custom kernels if on locked bootloader
Unlock bootloader - http://forum.xda-developers.com/xperia-z/development/tutorial-xperia-z-zl-bootloader-t2153261
To root you will need to be on a 4.2 ROM, once rooted you can install a recovery then you can install a rooted 4.3 ROM or custom ROM
Follow this method to root on stock rom - http://forum.xda-developers.com/showthread.php?t=2327472
(additional guide - http://forum.xda-developers.com/xperia-z/development/guide-how-to-root-101-firmware-lb-t2656698)
Follow this method to gain recovery - http://forum.xda-developers.com/xperia-z/general/ub-lb-xzdualrecovery-xperia-z-qa-thread-t2477769
Should be ready to flash stuff

thanks a lot!!!
was lost into all the new infos...
so to install 4.3 - 10.4.1.B.0.101 no need to unlock, right?
(I only need the sony rom)

Correct, you do not need to unlock the bootloader if you are going to install the 4.3 - 10.4.1.B.0.101 ROM.
You can either do this on flashtool by flashing a 4.3 FTF or you can root and install recovery and flash a rom zip file

Cannot Install Custom Rom Xperia Z for T-Mobile (C606)

Hello,
I have been trying all day to install a custom rom on my Xperia Z for T-Mobile. I have succeeded in rooting it and installing the recovery, but it looks like the bootloader needs to be unlocked. I have followed this guide and have rooted and installed the recovery but when I install a custom rom, such as paranoid android lollipop, it gives me an error and I cannot reboot into a rom so I have to run the Sony PC Companion tool and repair the device. I now have a completely stock Xperia Z and wanted to know the best way to install a custom recovery and flash a rom. I have tried unlocking the bootloader but it says bootloader unlockable no when I dial service, even after installing root and recovery. I have tried anyways and it says operation not permitted when I try to cmd the unlock code into fastboot. I was hoping someone could help me and guide me on how to fix these issues and finally install a custom rom.
Thanks

T-mobile Z bootloader cannot be unlocked, therefore you cannot flash custom kernel, therefore you cannot flash a ROM that uses anything other than stock kernel. Look for the "LB" tag in the ROM title, these are for phones with (L)ocked(B)ootloaders, and should be STOCK based ROM's.
Just make sure you follow proper procedures when upgrading to different versions of Android.
