[Q] Keeping Root exploit on different roms. - Xperia Z Q&A, Help & Troubleshooting

Hey guys, with the no bootloader unlock exploit, i could obtain root without unlocking the bootloader.
However, i just want to ask, will the root still be kept if i flash on a different rom, or flash on the new FTF 434 firmware?
Thanks :3

Can you flash roms on locked bootloader devices that are rooted?

It is possible to flash roms on locked bootloader devices. Wait till the devs support it. The xperia s has roms for locked bootloaders.

there is already a locked bootloader CWM recovery available. so i would imagine that you can flash stock based roms..

Im not sure what the advantages is to unlock the bootloader then obtain root, now as there is a way to root without unlocking bootloader..

So read under android development
At a guess unlocked boot loader will allow installation of custom roms
Root will allow running software that requires root like root explorer

Are there any ROMs worth installing yet? I feel like its a lot of bloatware that I dont need are installed with it so it would be nice to clean it
i think everybody that even visits xda know what root is, but unlocking BL vs locked prior to root?
if it`s only the custom roms that cant be installed I`m keeping mine locked and just gonna root. im quite happy with the stock rom.

You can install stock based ROMs with a locked bootloader, as long as you stick to Sony's kernel.

[Q] Buying Xperia Z need some questions answerd

Hey there!
I'm about to buy a Xperia Z but I do have a few questions first:
1. Whats the difference between locked and unlocked bootloaders. I mean if I root my Z with locked bootloaders will I be able to flash every Custom Rom or are there Roms which will only be working with unlocked bootloaders?
2. What exactly can the Flashtool do? Is it a bit like ODIN for Galaxy Devices? Does the Z have a Download mode like the Galaxy S3 so I can flash a Stock firmware anytime I want?
Thanks for ur answers.
1- custom roms for locked bootloader are few and limited.
You need unlocked BL to flash custom.kernels,cm,aopk roms....
2-Yes flashtool is same as odin but with many more features,like rooting,unlocking the BL,flashing stock roms.....

Locked BL you can still root but cannot flash custom ROMs (but I'm not 100% sure on that see post above by gm007)
Unlocking the BL you lose DRM keys FOREVER and BE2 won't work anymore (some claim they can still make BE2 work)
FlashtTool can easily flash STOCK ROMs without rooting or unlocking BL.

Before yesterday I had a locked BL and I had a custom rom, you just can't install a custom Kernel when your BootLoader is locked.
Unlocking your BL will cause your drm keys to be lost that's true, but you can save the partition your keys are stored on and you can re-flash the partition to restore the DRM keys. (Did that yesterday) It can be tricky though, Gm007 knows everything about it

[question] lock bootloader

Hello, I unlock the bootloader of my phone and I was flash stock rom with rsd but the bootloader is unlock again... I'm no can receive ota update :, ( sorry for my English bye
Sent from my MB886 using Tapatalk 4 Beta
I dont think it can be locked again. Hmm. It's weird. I have flashed many times and havent seen it be locked after flashing.
I have looked on Motorola forums and searched Google but could find not any method to re-lock the bootloader. Flashing stock or custom roms would not re-lock my bootloader.
Since you have an unlocked bootloader, why not root and install cwm? This way, you can install custom and stock roms.

Flash.with locked bootlader

Well.I just got a used.Sony z
I.rooted. Via.one click. And installed twrp with the apk.
My question is can we flash roms without no issues even with a lock bootloader on this device seeing as I opted out to flash recovery with the locked bootloader and if that's not the case how do I find out if my bootloader is unlockable version

If you are locked, you just need to flash roms flashable zips via recovery. Look for "LB", which stands for Locked Bootloader, threads under the Development section, and you'll find compatible software with your unlocked device.
If your device is from a carrier, chances are you are locked with no way to unlock. If your device number is C6606, you are not able to unlock, no matter what.

Yes I am....t-mobile.my device says it's not unlockable... I have checked
But I just wanted to verify if I'm boot loader Locked.
Just needed to..verify if I'm.locked can I still flash Roms via twrp.

If your bootloader is locked and you can't unlock it you can still flash roms but only those bases on stock. The problem with the locked bootloader is that you can't install a kernel that isn't signed by Sony. So no CyanogenMod and derivatives.

Need help...!! camera functionality not working after unlocking bootloader

1stly i have 4.4.2 (.757) running on my z1 and i downgraded to .534 and i rooted the device by vroot and backed up the DRM keys successfully.. and then i flashed to .290 and unlocked the bootloader by flashtool and then downgraded to .534 and then installed the dual recovery and then flashed using the flashable recovery using recovery and then i found that camera is not working properly.. camera is opening and when i press the shutter butter its trying to focus the area and after focusing it freezes and doesn't shutter... so this is my problem... please help...
So much fail.
Do not use vroot, it sends your imei number to an ip address in China.
Also, unlocking your bootloader on 4.2 will break your camera, it clearly says so on the Sony official site about unlocking your bootloader.
Now, the solution.
Restore your ta partition.
Use pccompanion to update to the latest firmware
Unlock your bootloader again
Flash a custom kernel of your choice
Install super user app of your choice

.534 is 4.2 FW. the camera will not work with an unlocked boot.
Follow the advice I gave above

yeah..!! i have done it.. thanks
but i have unlocked it in 4.3 does it make any sence by unlocking the bootloader in 4.3 and i didn't get any recovery mode... so.. i downgrader to 4.2 and installed the dual recovery as the thread says it needs .534 firmware to root properly...

I have to ask
Why are you unlocking your bootloader? What have you done it for? You do not get a recovery mode just by unlocking the boot, you have to flash a custom kernel with recovery in it
You either do all the downgrading and install dual recovery if you have a locked bootloader
OR
You unlock your bootloader, flash a custom kernel with recovery and install super user app
there is no need for both approaches and that's why you are getting problems

i unlocked the bootloader... i didn't find any recovery after unlocking so i followed the xzdual recovery process... but is it safe to flash a custom kernel.. and by installing only recovery without kernel does this doesn't help..

Why did you unlock the bootloader? What did you want to do with it?
You can not install a recovery without a custom kernel, xperia devices have no recovery partition, it can only be installed by pushing the ramdisks to the system partition or by flashing a custom kernel.
Please follow the advice I gave several posts ago.... that is your solution.
Then spend some time reading up on xperia device flashing.
1) Xperia devices have no factory recovery or recovery partition
2) Unlocking the bootloader is the fastest and easiest method to root and get recovery (If you are allowed to do it)
3) If you cannot or do not want to unlock the bootloader, then go through the downgrade, root, dual recovery process...

Greg said fifteen times - follow his guide for here.
Yoy can't flash custom kernel especially not fastboot custom kernel on locked bootloader.
Whole purpose of unlocking bootloader is to flash custom kernel.
You are confused with all this informations, I would recommend that you read few things here on XDA to understand terms and other things.
You could seriously damage your device with just one wrong step.
