[Q] Custom Roms for Xperia Z Ultra C6833 locked bootloader help - Sony Xperia Z Ultra

Hi
I am a noob when it comes to android but i have managed to get root access on my device and i have installed CWM recovery, my question is how do i now install a custom rom, my device is bootloader unlock allowed No, so i am aware that the kernel can not be modified and this will limit the roms that can be installed, but after hours of searching i have found a hand full of roms that say they will work with locked boot loaders but stop the phone booting. am i installing them wrong?
Thanks
Josh

You can only flash Roms with locked bootloader, like modded Originalfirmwares, you download it copy it on SD Card and go in CWM flash the Rom and then do a whipe and restart and enjoy

I am trying to install http://forum.xda-developers.com/xperia-z-ultra/development/rom-stoneui-hd-118-t2952024, i have root and cwm i install from my sd card and reboot but it just shows the sony logo untill i hard reset and reflash 14.4.A.0.108.

Xperia Pro recovery mode to install CM ROM questions

Hi,
I've Xperia Pro MK16i, with stock 4.0.4 ROM, boot loader unlocked and rooted.
I really want to install recently released CM9-RC1 ROM but have been unsuccessful probably due to CWM recovery.
I was only able to install CWM auto installer which would only boot into recovery if i do it from within booted stock rom, but not manually when i reboot and try to go into recovery mode. i tried all key combinations like volume key down/up when at reboot sony logo flashes bright and led turns blue for a second.
Nevetheless i tried to install CM90RC1 by following official cyanogenmod instructions in which i failed when the guidelines states to fastboot and flash boot.img extracted from CM9-RC1.zip file and then reboot from fastboot. it just stuck there and would not even flash sony logo.
I relocked the bootloader and installed the stock ROM through Sony PC companion repair option.
Now i have again unlocked the bootloader and rooted. but not sure how to proceed now.
I guessed may be i need custom ROM with CWM recovery builtin. i came across this site
http://forum.xda-developers.com/showthread.php?t=1315904&highlight=108
kindly guide me if the link above will help me installing Cyanogenmod ROM and does it come with CWM recovery built in.
Also whats the difference between multiple downloads on the above link like FXP129 and CM9 baseband?
What files do i have to download now, to install Cyanogenmod ROM?
Regards

No, you can flash CWM straightaway.
And don't forget, YOU CANNOT RUN CUSTOM KERNELS ON A LOCKED BOOTLOADER. YOU CAN ONLY RUN STOCK OR STOCK BASED ROMs.
say no to Drugs and ICS!

You can install CWM Recovery without unlocking bootloder but you have to root your phone first.
If you unlock your bootloader, you can flash any custom kernel which is built fir your device which will have CWM Recovery in it. i.e, you don't need to install CWM Recovery separately.
Once you have the CWM Recovery, you can install any custom ROM.
& don't worry, ROMs are built in large packages so that they're compatible with a number of devices. It doesn't mean that whole package will be copied as is to your root. Instead, you'll have some more free internal memory....

Happy Flashing!

tnx, so what do you recommend, unlock bootloader-----flash cwm-----and rom. Kernel and rom are in same file everything could be flashed from device, cwm ?
tnx again
First decide whether you want to unlock your bootloder or not. I recommend you to unlock your bootloder but it WILL void your warranty but you'll be able to do alot more than Locked Bootloder like using custom kernels & you'll be able to flash ANY available ROM built for your device.
So 2 options for you:
1. If you want Locked Bootloder:
Root Your Phone > Install CWM Recovery > Flash any stock based ROM using CWM Recovery.
2. If you want Unlocked Bootloder:
Unlock your Bootloder > Flash any Custom Kernel (Which is compatible with ROM you want to install) > Install the ROM using CWM Recovery.
For unlocking bootloder & other information, follow this link: http://forum.xda-developers.com/showthread.php?t=1590383

Rooting Orange Z2 with locked bootloader

Hello, I recently bought an xperia Z2 from someone that had it from the french operator Orange.
Running on a heavily bloated lollipop 5.0.2 with a build number of 23.1.A.1.28 D6503 with a locked unlockable bootloader
Being a samsung user all my life, this seems a new territory to me, I first wanted to clean everything up and have it running on CM12, that seems impossible because of the bootloader lock.
Then I failed rooting it and got really confused. the device also doesnt boot into recovery AT ALL
Can you please help me root the hell out of it and clean all the crap that Orange put in it? and also would you please suggest a debloated clean stock rom(kitkat is preferred)
Thank you so much for your time, I'm looking forward for you replies
Use KingRoot for rooting,install BusyBox, then install custom dual recovery with XZRecovery finally flash SuperSU zip with recovery , here's a link for all the files needed http://www.mediafire.com/download/894tuibsb2a75bm/wts.zip
Well, my dear friend, I failed twice doing that, now im running a clean factory reset and going to try again, will let you know
Flash android version 4.4.2, root this version and then flash the firmware of your choice via recovery (make sure it is a prerooted one, that comes in a Flashable Zip form)
As I know, Sony devices doesn't have accessible stock recovery
You can boot into recovery only after installing custom recovery like :
TWRP - CWM - Philiz Touch
If I Helped, Leave A Thanks ?

Can't access anything

So, I think I finally did it. I broke my phone.
I wanted to flash the new Existenz Rom 6.0 and the flashing worked fine. The phone started and it got stuck in the Xperia logo. I than downloaded the Bootloop Fix. To make sure nothing goes wrong I wanted to do another factory reset. Somehow, my phone uses two roms (Philz custom recovery or something like that (I flashed the rom with this) and a TWRP Recovery). My phone booted into the TWRP (which it usually doesn't do) Recovery and I thought "Well, I can do a factory reset here". So I did the advanced reset but after restarting I can't access anything! When I turn it on, there is still the Sony Logo but if I press up and down I can't access none of the custom recoverys. I'm truly desperate and I can't afford a new phone. Can someone help me how to fix this?
@DerDokktor
XZDR and similar recoveries for locked bootloader reside in /system partition , when you wiped your system you also wiped the recovery...
You'll need to flash an .ftf firmware with flashtool to recover your phone. If you want root and a locked bootloader flash a KK or LP ftf (as MM is not rootable yet), then root it with kingroot or something else you like, install XZDR from your computer and then you can go to the recovery again and flash existenz rom or any prerooted rom you want.
You could also flash a MM .ftf directly but then you won't be able to root it without unlocking your BL.
If you need help with flashtool follow this guide:
http://www.xperiablog.net/2015/03/1...peria-lollipop-using-xperifirm-and-flashtool/
Edit: the first steps of this guide are to create your own .ftf , if you already have an .ftf downloaded you can go straight to the "Now that the FTF firmware file has been created, you need to flash your Sony Xperia device." section of the guide.
