Hi,
I know this is an application issue but;
I have an Xperia Z5 Premium (I already posted this in Z5 Premium forum but no replies there). So I have a Xperia Z5 Premium with unlocked bootloader and with DRM patch installed, I do not have the DRM keys backed up either.
I launch Snapchat with all this, front camera works fine as it should, but I wanted to change my phone back to stock, I reinstalled stock firmware and locked the bootloader via flashtool. I launch Snapchat, and the front camera glitches very badly - It's showing green spots and tears all over the screen and lagging horribly, this is completely fine in the Sony Camera App.
Now IF I unlock my bootloader and install a DRM patch, this issue is fixed.
But I don't want to unlock my bootloader and root my device, I want it to be as stock as possible. Is there any fix to this issue?
Can someone else test this on their Z5 / Z5 Premium without the DRM keys and have bootloader locked.
Thanks
I have the same issue you are describing, but I did unlock my bootloader, I didn't install the drm fix though edit: This issue is not present when I use a custom rom so I guess it has to do something with the drm fix
I don't know how to fix this, I don't want to unlock my bootloader and/or install a custom rom but I really want Snapchat on my bootloader locked Xperia Z5 with stock rom and no DRM keys.
I'd be really grateful if someone helps me with this.. I already regret not backing my TA folder up a lot and this is the last thing I need.
I found out that this happens only when the bootloader is locked, not when unlocked.
Is there some way to fix this please?

So this is my first xperia device since the Xperia Arc was released way back when, and I have been using HTC phones. Which are WAY different in terms of Rooting / Unlocking / Etc.
So long story short, What I want to know is what Can I currently do to the Xperia Z5? I see there's no custom ROM's yet which is expected , but I see mixed results about unlocked BootLoader & Root , the main thread says that a bootloader hasn't been achieved, yet there's a few root methods which have been successfully completed , requiring an unlocked bootloader, so naturally you could see the confusion..... Can someone point a SONY noob towards the right direction in terms of bootloader unlock / rooting? Running the E6653 ( not sure if there's variants )
Basically you currently need to unlock the bootloader to to get root. And doing so loses some features which u may possibly never get back. So most people are currently waiting for another way around to be figured out

My heart literally dropped as I read this..... Because I already unlocked the bootloader. I'm assuming it's the bootloader unlocking that destroys some features? If so , which ones?
And how can I tell if they were actually destroyed / bootloader unlock actually worked
Unlocking the bootloader on Xperias will delete the device's DRM keys. These keys are unique per device and once gone are gone forever. They're needed for Image enhancements like X-Reality/Bravia/Super-Vivid and some camera features too - low light and noise reduction algorithms I think. Sound improvements (ClearAudio+...) too.

Well crap lol, is there any way to actually make sure that the DRM's were deleted or if the bootloader unlock was actually successful? I still have a few days to swap the phone out if anything goes wrong ( Bell wouldn't be able to tell a bootloader unlock ) , I haven't had enough play time with the phone before the process to actually see a difference with the camera, I read somewhere that if TrackID works, than it's not unlocked, is that true?
I haven't checked XDA in awhile because I gave up hope of ever having a good root solution for the Z5. But I have been looking around lately and have seen roms such as [ROM][E6653] Slim Stock 32.0.A.6.200 and the [LP][UB][ROOT][DRM][KERNEL][RECOVERY](TWRP3.0) Z5 ADV STOCK KERNEL (2016/03/04) (v1g) kernel. So as of now, I'm a little lost here. Of the 15+ Android phones I've had, this has been the most complicated.
I understand that root is possible by unlooking the bootloader and that as of now, there is no root solution for a locked bootloader. Are you now able to unlock the bootloader and root with phone without losing any features?
You still lose DRM. There is a possibility to trick the phone into thinking the DRM keys aren't wiped restoring the DRM features after unlocking the bootloader but the DRM is still missing.

So you'll lose DRM keys but you can still retain all the features? I hope the same will be true for the Marshmallow update.
That's right. We don't have a kernel to run modified system images on MM just yet so can't confirm nor deny it working.
Hello! I'm new here and actually the main purpose of my registration on this wonderful website is the amount of helpful and skillful people I saw in various threads I read before, giving me hope for the solution of my problem.
As stated in the title, I'm currently unable to get OTA updates on my phone.
Some time ago I unlocked the bootloader (so my bl is unlocked now) in order to have my Z5 rooted. Apparently something went awfully wrong while flashing the TWRP or perhaps I was just awfully stupid and missed a step... Anyways I ended up without any OS and started searching on the web for some solutions.
I came across FlashTool and XperiFirm, then downloaded and flashed the (at the time) latest firmware, which is the one i currently have (Service Menu shows "GENERIC_32.2.A.0.224"). So now my phone seems perfectly fine: stock rom, no custom recovery (as far as I know), no root privileges. The only problem it shows is the fingerprint hardware that stops working every once in a while; something a simple reboot fixes.
But I have been unable to update since then, with my "software update" tab showing no available updates (nor could I get one via Sony PC Companion, furthermore getting errors while trying fo repair software) while under "diagnostics" it clearly says "new software available".
I just want to get everything back as it was before, and to get my OTA updates to work; I'm not interested in custom ROMs or custom recoveries or SU.
I apologize in advance in case an identical thread had already been opened and closed; I hope you guys can help me solve this mess I did.
Thanks a lot
I found out my problem is connected with the DRM Keys loss caused by unlocking the bootloader. I'll try this out: http://forum.xda-developers.com/xperia-z5/development/root-automatic-repack-stock-kernel-dm-t3301605

Once you have unlocked the Bootloader ota updates don't work EVER only manually flashing the ftf via flashtool will get you updated. If you unlocked the Bootloader without backing up the drm/ta keys then re-lock the Bootloader ota updates will Not work. If you unlock the Bootloader and then re-lock with previously backed up drm/ta keys ota updates WILL work.
The drm fix does NOT replace the missing drm/ta keys it merely tricks the device into thinking that those required for x-reality, low light conditions, and noise reduction in the camera are there to reactivate those features.
Also DO NOT try to use a other Xperia devices drm/ta keys on your own unless you want a permanent paperweight.

Ah, so I should have backed those up before unlocking the bootloader. It seems I'll have to spend a few minutes on flashtool every once in a while to get updates, nevermind.
Anyway is it worth it to try this DRM fix? I did not notice any changes to the quality of the camera.
And another noob question: if I flash this "modified kernel" will my device be wiped? Or I just flash it, reboot the phone and enjoy DRM features?
Just a quick update to let you know, I have installed the drm fix and rooted, the funny thing is that now I receive ota updates.. But of course I'm unable to install them. Not that I want them anyway, so no problem. I have reconsidered the potentiality of a rooted device and started to appreciate the benefits; thanks for the help
I have not received the 32.2.A.0.305 update for my Z5 yet, so I went to XperiFirm to check which region my device's firmware is from. It turns out the firmware is CDA 1298-2996 (South Africa).
I live in Australia and wish to flash the Customized AU firmware with CDA 1298-7277. I want to do this so that my device will be updated and will be using the Australian firmware.
My bootloader is locked; is flashing possible without unlocking the bootloader?
Will flashing a different firmware potentially cause damage (my device is not network locked, and single sim E6653).
Will this affect my warranty / DRM keys?
Thank you in advance, I appreciate any help :angel:
You are safe to flash almost any E6653 Firmware onto your E6653
Obviously dont flash test firmwares or ones that May lock your sim

Thank you And the DRM keys should not be affected? I have read that unlocking the bootloader only affects the keys.

Flashing a FTF shouldent touch DRM At all.

you can flash and what ever with your device, DRM keys are safe!
when u ulock bootloader, the device WIPE user Data and sony partitions (TA (trimArea) partitions) and DRM keys and FIDO keys will be lost!
this $h!t is with sony only!!
i rooted my fone and having modified kernel having DRM stimulation installed. its working fine now.
- at any given day, to a thirsty user who wants to CONTROL his Xperia to the most. i would say, ignore drm keys and make a deal with devil to have root access
- however since Xperia Z5 (unlike latest xperia Xseries) came out on LP kernel. so u can FLASH LP kernel and root it with app like kingroot and extract your DRM keys to windows pc and back it up. now u can flash the LASTED Android back on you Xperiaz5 and unlock your boot loader to have root access.

Thanks for the advice, I will look into it in the future when CyanogenMod improves and I need to unlock the bootloader to install it. My main incentive for this would be to greatly improve the camera, which we all know takes very washed-out photos.
I have just gone through the firmware flashing process. Thankfully there are many guides available and it all worked just fine, so I am using the current, correct firmware now
The worst part was just the waiting and suspense (feels like a lot could go wrong).
Thanks again Envious_Data and YasuHamed!

i had flashed Cm13 on XperiaZ and inbuilt camera app of CM13 was worse than xperia! and if you think you z5 camera isn't working properly then God Help you when you won't have DRM keys in place! because the DRM keys actually enables feature of camera which wont be activated if DRM keys are lost
nothing will go wrong! be confident! sony devices are Hardcore stallions! once you nail them! they will be your pet!
So I want to unlock my bootloader and I noticed it can't be selected on Sony website. Do I click the xz or what do I do?
unlock
you can select XZ
it works with XZs
Thanks. Gonna give it a go
Hi guys, its a silly question...do we still lose DRM keys when unlocking bootloader? Like with Z series?
Sony provides the ability to unlock the bootloader of the XZs on their website... If I do so, without doing any other changes, will this result to losing DRM keys or whatever else that's important? Hope anyone can clarify, thanks.

i really want someone to try this to save drm keys
https://forum.xda-developers.com/xzs/how-to/dirty-trick-t3759905
i don't have xzs in my country otherwise i would have tried my self!
xzs is basically XZ so if android 6 of xz can be flashed on xzs before unlocking bootloader and then running dirtycow script!... iam 99% sure it will work! both always run on same buildnumbers and kernel versions!
