Can i flash ROM with locked bootloader? - Xperia Z3 Q&A, Help & Troubleshooting

Hi everyone. I am the owner of a D6603. I have seen many guides regarding to root and recovery without unlocking the bootloader. My question is: Can i flash ROMs with this custom recovery even if the bootloader is locked? If it is possible, will there be any extra risk on doing this? I really want to test some custom roms, thanks in advance for your answers.

Only if it is based on the stock kernel, otherwise you will get a bootloop

If you want to try some custom roms that are not based on the stock kernel, you can just backup the TA partition and unlock your bootloader, then if you want to go back you can always lock it again with the backed up TA partition.
If you do that, I suggest you you save it in multiple places.

I can't actually unlock the bootlader because my phone is sim locked and it says "Bootloader unlock allowed: No" in the service menu. I'll just try the stock based ones. Thank you very much for your reply!

Root Without BL unlock

Hello guys
im looking to root my OPO, but i dont want to unlock the Bootloader or install a custom recovery, just want a method to root so i can install Xposed on the stock CM11S rom, is this actually possible?
Why not just unlock the bootloader? Your warranty isn't affected by it. You lose nothing by unlocking it, and you gain nothing by leaving it locked.

Like @timmaaa mentioned, you lose nothing when you unlock bootloader. Not only that, it is the recommended and futureproof approach to do so. Unlocking the bootloader wipes your phone completly clean. Suppose somewhere down the road you want to try different ROMs, you'd realize you cannot do so without losing your data. So you'r much better off unlocaking your bootlaoder right now.
But to answer your question, no. It is not possible at a simpler level. Unlocking the bootlaoder give you access to all the partitions on the phone. What you need access to specifically is the recovery partition so you could flash a custom recovery and install the SU binaries onto your system. through that recovery.
What others have said, unlock the bootloader there's no problem with leaving it unlocked.
You're given the key to unlock the bootloader using a command. Use it and make your life simple. It's like saying you have the key to your house but you want to get inside the house without unlocking the door. Just use the key and make it simple.

Perhaps you felt like I did, worried that you are ruining your phone or your ota ability.
Unlocking the Bootloader is painless aside from having to reinstall all your programs. Everyone says it wipes the os, but what they don't tell you is that you don't have to dig around looking for the proper version to reinstall. You just type a code, and the phone reboots fresh like a factory reset, ready to go. And installing the custom recovery is easy, and it works perfectly with ota updates.

[Q] Android Lollipop: How do I gain recovery? [Need Help]

I have not rooted my phone yet and previously come from using nexus devices.
I'm on stock lollipop rom and was wondering how I should proceed.
step one would be backing up the TA partition.
following that, unlock the bootloader. After that I was wondering if I need to downgrade to kitkat to continue or if I could flash a kernel with twrp and try to get into twrp, wipe everything and flash cm12.1 + gapps + supersu and proceed from there.
My question is, do I need to downgrade to kitkat stock to proceed or is there a way for me to gain recovery and flash a rom without downgrading?
you will need to downgrade to KK to get root access then install a stock rom that had been pre-rooted for lollipop, you don't have to unlock the bootloader but if you do then you can use a kernel that has recovery built in

But to flash a rom one does not need root, just recovery, or am I wrong there? Wouldn't it be possible to flash a kernel using fastboot just to gain access to twrp (I know that would cripple the stock rom), and then wipe everything and then just go ahead and flash cm12.1 using a microsd card?
I might be totally wrong. If there is not other way I guess I need to downgrade.
Oh and my end goal is to flash cm12.1.

But you cannot flash a kernel with a locked bootloader, and you cannot backup the TA without root...
So, you need to root before unlocking the bootloader.
So, downgrade to KK FW .93, root, backup TA partition (If you are going to unlock the boot, otherwise there is no point), install recovery, flash a pre-rooted lollipop rom.
No need for unlocking the boot at all unless you want a custom kernel
But if you want CM12,
downgrade to KK FW .93, root, backup TA, unlock boot, install a recovery of your choice either by a LB way (e.g. dual recovery) or by fastboot a boot.img, flash CM12.1

Ah I see, root is needed to backup TA partition.
I know my bootloader needs to be unlocked as I flash Cyanogenmod 12.1 on it. I fell more secure using fastboot soo I'll probably go that way.
So to downgrade, do I use flashtool and find a kk fw .93 ftf file to flash? If I understand correct, this can be done without unlooking the bootloader.
Then from there I'll have to root with looked bootloader, backup TA partition and then unlock bootloader, and then flash kernel with twrp and then proceed to flash cm12.1 or anyother custom rom.
(Sorry If my question is a mess).

Well there are unofficial builds with fixes from members who has the Leo build. The official one does not have all fixes as of yet. There are cm12.1 unofficial builds out now. Being able to test out the latest and greatest is the beauty of it.

I agree, development, testing etc. I was more wondering why people experiment with such ROMs when they lack basic knowledge about flashing, TA etc. But it's a bit OT.

For some its a first step into something new, it is always a learning curve. Some just like to have the "latest" version.

Coming from a different device does not mean that one does lack basic knowledge. I previously used lg g2 and prior to that I used nexus 5, nexus 4 and older devices. All could be managed using fastboot. Those phones does not have drm keys that needs to be backed up. Hence I did not need that knowledge.
Either way, thank you for enlightning me. I felt to ask here in Q&A section rather than being sorry about not asking.

That's fine, I totally understand you! Hope to be pro xperia user soon haha :silly:
@gregbradley Had a noob moment here and now I'm stuck. I tagged you incase you would know how to help me.
So I downgraded to .93 kitkat. All worked well.
Then I managed to root it using giefroot. All worked well.
Then I installed xzdualrecovery. It booted into twrp, I wiped everything beside internal storage and tried to flash cm12.1. I received an error.
I forgot to unlock the bootloader (ofcourse).. which is the mistake I did.
So now I'm stuck. When I turn on the phone the sony bootsplash screen comes on and it does not go past that, due to my device not having a rom.
I tried holding down the volume key and plugging in the device to my computer. My computer does not recognize what device it is but it does make a notification sound saying that I have connected a device to my computer. Fastboot doesn't work on lockedbootloader as far as I know. The flashtool recognizes the device as a flash device for around a minute when connected to the computer using volume down. After a minute my device just turns off and on leaving flash mode. So that's the current status.
Do you or anyone else have any suggestions to how I can revive my phone?
and yes I know, I feel like a noob!
Never mind, I gave it another go with flashtool and managed to get it boot!
and yes, I feel like a pro!
Don't forget to backup the ta patition before unlocking the bootloader.
Also no need to wipe system when flashing

I backed up TA partition 3 times. I've been getting error in twrp when I try to flash cm12.1. I did infact wipe everything even system. could that be the reason for me getting an error in twrp? (can't currently remember what the error was but i wasn't able to flash it.). Is there some problem caused by wiping system?
I finally understand Flashtool and have no problem using it. I also have tested restoring ta partition so I know how stock sony works now. It's just custom roms I have trouble installing. I've been using xzdualrecovery and that recovery pushes me automatically to twrp after I install it. Is there some other recovery i should use instead?

Use NDRUtils app to boot to a different recovery
Or just press volume up when the phone vibrates twice when you are booting it to get to CMW

i would wipe really everything despite usb otg and external sd card in advanced wipe of twrp before succeeding.
tell me if that works for you
um, i read you already had that issue again even after unlocked bootloader, try flashing a rooted lollipop .zip in recovery.
and then try wiping and flashing cm12.1 again if a full wipe (also sdcard) doesn't work

Root without losing DRM Keys?

Hello,
Is it possible to Root my Sony Xperia Z3 D6603 which is currently running Android 5.0.2 without losing the DRM keys?
I don't want to have to roll back to 4.4.4, or lose any of my files.
I have a pretty slow internet so i'm not a big fan of downloading stuff, I'm just psyched to check out Xposed if it exists.
No, you must roll back to a FW ending in .93 which is KK, then root, then install recovery, then update via a pre-rooted flashable zip
I would not hold my breath for a lollipop exploit. The main reason to find one has gone (i.e there already is a way to get root on lollipop with a locked bootloader)

rooting has nothing to do with the DRM keys
you have to downgrade.
you will lose your data.
you have to download a kitkat stock rom.
No way around this if you want root.

Not if you do not wipe the data partition of flash the data partition from the FTF. You will get a lot of FC's when downgraded but this is not an issue as you will be upgrading immediately to Lollipop anyway

But why revert if he is unlocking?
If he is unlocking he can flash a kernel with recovery and root via TWRP.
Before back up TA.
And after restore the DRM keys.

Please read the OP, he does not want to lose DRM keys, hence he needs to root without unlocking the bootloader first.
Also, if you have a custom kernel installed you cannot have DRM keys running, once you restore them using a TA partition restore you relock the bootloader and cannot boot on a custom kernel.

There is a thread about restoring some functionality but it does not restore to 100% stock compared to when people have a stock ROM with DRM keys installed, and like I said, READ THE OP, he asked for a way not to lose his DRM keys, not to have the functions associated with them.
If you unlock without backing them up, you cannot restore them, FACT!

You said to root by unlocking the bootloader first, then backup the TA so you are wrong. Editing your post after the fact does not change this, adding the line "Before backup TA" does not make you correct as you have to root to backup the TA.. so when you say "why revert when he can just unlock", that's why.
And finally, restoring the DRM keys after unlocking means you get a locked bootloader, so you cannot boot a custom kernel so you lose root...
The point is now moot, and you need to remember my advice on this, keep it in PM's

How do I revert back to stock and lock bl?

Will be selling my phone shortly and need to flash it back to a stock rom (UK) and lock the boot loader, I am getting a bit lost searching around trying to find the right files to flash with as from what I gather it has to be a UK stock file? I would also like to relock the bootloader / unroot so it's ready for sale.
Hope someone can help, thank you.

If you took a backup of your TA partition you just need to flash that back in order to relock the bootloader and restore your DRM keys.. If you didn't take a TA backup then you cannot restore your DRM keys anyway.
You can flash any FTF to go back to stock as all FTFs are stock, just from different regions and carriers. If you are from the UK then flash any UK FTF. Use flashtool to download the FTF and flash it.

You can do it using flashtool. The warning will probably go (I have not done so cannot confirm) However, relocking the bootloader without the TA partition will not restore any of the DRM functionality you lost when unlocking the bootloader, and regained by flashing the DRM fix (which can only be used on an unlocked device). Therefore, if you sold me the device without telling me you had wiped the DRM keys I would be pretty annoyed and would come looking for you if you tried to charge me anything near the going rate.
I would leave it unlocked and advertise it as such.
Greg
If you use flashtool to relock your bootloader the message does go away I've done it before and can confirm that it does.
But you won't be able to patch DRM. Better stay unlocked and flash a patched kernel.

Is there anyway for flash .zip files without unlocking bootloader or using TWRP?

I want to use google camera app but it needs camera2API but at the same time I don't want to unlock my bootloader or use TWRP, I searched and I found that flashing .zip files without useing mentioned operations but I couldn't able to find any new threads to do this in android 9.

What you are trying to do requires flashing to system partition, flashing custom zips to system partition requires either root or TWRP(TWRP requires unlocking bootloader, it may or may not be possible to root the device without unlocking bootloader), you can't do it without one of these two things.

Thanks for your reply I think I'm going to unlock my bootloader but I'm still not sure because when I look to sony's site it says that if you unlock your bootloader sony can charge lot of money for repair, is that true or there just trying to frighten us to not unlock our bootloader because this is also my first device and daily-driver that I try to do these things so I'm little bit nervous about that. Any advice?
