[Q] Locking, Unlocking, DRM, what do you lose?

Hi,
Just ordered my z3c, looking to put CM12 on it. I'm coming from a Nexus 5 but I've used Samsung devices where there was just about no reason to keep the stock rom, but never heard of DRM apps and functionality in those... I've read a bit about the locking/rooting/DRM situation with these phones, but I haven't found a good, detailed answer on what it is that you actually lose by flashing a custom ROM like CM12 and/or unlocking the bootloader. So my question:
-What apps/functionality is lost when unlocking the bootloader?
-Does losing the DRM keys even apply to CM12, since I'm guessing they can't be used by anything in CM12?
-Do I need to unlock my bootloader to flash CM12? No TWRP from what I've gathered, but you can flash the CM recovery?
Thanks for the help.

Correct me if I'm wrong...

I have read that it's stuff like TrackID, Bravia engine, PS4 Remote Play?

Yes, because in order to flash CM12, you need to flash a custom kernel. Locked bootloader will not accept custom kernel. So bootloader must be unlocked.
-Do I need to unlock my bootloader to flash CM12? No TWRP from what I've gathered, but you can flash the CM recovery?

See above. For this phone, custom recovery is possible with a locked bootloader, as long as Root has been achieved. This doesn't mean you can go ahead and flash CM12 though! But you can flash custom roms that are based on the stock Sony kernel. (Make sure to check the post - some custom roms may be based on a certain build of the stock kernel, so you'd have to make sure your phone's stock rom/kernel is aligned with that)
Another thing to note is that it should be possible to backup your DRM keys (your TA?) if you have root on your device. This would allow you to restore the DRM stuff when/if you decide to re-lock the bootloader. Backing up the DRM stuff can only be done BEFORE the first unlock of the bootloader. Once it's unlocked, DRM is gone.

And the low-light improvement camera function as well - there is a patch over at the cross device section, but you should be aware of it nevertheless

yes, very important - once you root make sure to backup the DRM keys even if you're not going to unlock the bl and save a copy on several locations.

So from more research, the low-light improvement (probably the most significant loss), wouldn't matter if I used CM12, with the Google Camera, as it is a function of the Sony proprietary camera rather than a function of the underlying phone/camera firmware, correct? Would this be true of the noise cancellation and other functions, baked into the ROM/apps and not a function of the firmware?
I'll still backup the DRM keys in case I need them in the future...no harm in doing so anyway.

There's a thread comparing how photos look before & after losing DRM. This may help you. The low-light one is where you see a pretty big difference.

What about miracast and chromecast features? Any influence on this?

So my question is if you unlock the bootloader . You can restore the DRM so that funtion is back whilst keeping the bootloader unlocked?? Correct??

No , restoring DRMs will automatically relock bootloader and you will only be able to run them with rooted/unrooted stock firmware.
Though it is possible to restore DRM functions on custom roms but your keys are still gone. (until you restore them but then the rom wont run anymore since you willl softbrick your phone)
See here : http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672

Thanks for your answer .
I checked the thread but for that fix you do need a locked bootloader? So CM won't work?
The fix it more that you can restore the functionality you lost when you lost your DRM and need to restore functionality?
Anyways I am obviously going to back them up but still would wanna understand it correctly.
Am a little confused here. ??.

No you need an unlocked bootloader, there would be no point to restore DRMs on locked ones since you still have them . CM cannot work with intact DRM since they require a locked bootloader. CM 12 will only run with an unlocked one.--> DRM keys gone. But as CM 12 is not based on Sony stock it actually makes no use of the technology driven by the DRM keys. So there is no fix to "imitate" DRM keys like with stock based custom roms. This would only be possible if somebody manages to port the stock sony software to CM 12 (after lollipop release ) and make the device think its running stock with intact DRMs. And i dont even know if that is possible.

[Q]Stuff to do before unlocking bootloader/root

So I just got My OnePlus 3T and like most, would like it rooted! I have had experience with rooting and unlocking bootloader, but since My earlier devices were by Sony, there is a lot of difference. In Sony devices, there was no need to unlock bootloader to root, but it seems that for rooting 3T, I need to unlock bootloader. Even that doesn't seem difficult since there is this great guide with a toolkit. But My concern is that do I need to backup any partition before I unlock bootloader? Like in Sony we had a TA partition, which could be backed up before unlocking bootloader and would get wiped after unlocking bootloader. This is just for keeping it as backup and restore it to device if I decide to lock bootloader again. Also, will I loose anything if I unlock bootloader? Such as anything specific to OEM or camera functionality?

Nope. On OP devices there's no permanent penalty for unlocking. If you ever want to go back, you can re-lock the bootloader. But: unlocking and locking will wipe your phone. So you can't carry over root to a locked bootloader.

Okay, that helps! So to return back to locked bootloader everything would need to be like stock(no root, custom recovery etc.)
I had read somewhere about EFS backup and that it is related to IMEI number of the phone. This need to be done before or after the rooting process?
Also, would I need to disable encryption (as it is seen enabled in settings) and remove the fingerprint lock option before unlocking bootloader?
And just to be clear, I'm going to do following steps in the sequence to flash TWRP and root, Please let Me know if it is correct:
1. Unlock bootloader
2. Flash TWRP.
3. Flash SuperUser
all this with the help of ToolKit of OnePlus 3T. I don't need to take backup as the phone is new.
Also, I will be flashing the phh SuperUser for support with Magisk as mentioned here.

Hey, do you guys know if you can get official OTAs if you have TWRP installed?

Former Z2 user here @Mirhawk
I did the advice backup as a precaution. Then did your 1,2,3 steps. May I ask, why Magisk? Is Android Pay currently working with stock ROM + Root + unlocked bootloader?

NOT FOR 960U. You can hard brick (yes HARD BRICK) from flashing this on a 960U. We don't have the firehose programmer for these devices so you will have to send back to Samsung

Hi, I need to get everything clear until I reach the 7 days be prepare to unlock bootloader.
I from Mexico and have the G9600 model want to unlock bootloader to change CSC.
After we wait the 7 day to get oem unlock, first enable oem unlock and then CROM?
It's confuse because on others threads say if we wait 7 days and enable oem unlock the phone say need to factory reset and before reset boot on the OS and the oem unlock it's gone again and need wait another 7 days. So before enable oem unlock and factory reset when the phone boot to OS need to run CROM or wait other 7 days to enable oem unlock again and then run CROM? Or this particular model don't need to factory reset before enable oem unlock?

Dear ho do format the phone? On every of the attempts, got error 21 and also footer error.

Fake global

Hi.
Unfortunately, I bought a k20 pro in the global version (aliexpress).
What do I have to do to not have brick? log in to mi account on the phone and Install the original china rom in mi flash and tick Clean all "option (not lock). Then wait again for the unlock bootloader?
having a global rom from aliexpress I can flash twrp right away and change rom ? Non Brick?

Basically the trick is to make sure you never accidentally relock the bootloader.
This normally happens if you've stuffed something up and need to flash a fastboot ROM. When this happens ALWAYS remember to change to 'clean All' when flashing with the Mi Flash Tool.
I assume the bootloader is already unlocked. If so, then you're 7 days ahead of the game and can go ahead and install TWRP and any other ROM of your choice. As long as you do everything correctly then you should have no problems.

Yes you can install TWRP and change the ROM.
The normal reason to flash a Chinese fastboot ROM is when you have done something wrong and soft bricked the phone. But yes you would also do this if you wanted to lock the bootloader again.

I was in the same boat. Just flashed the official China ROM via mi flash including bootloader relock. After I applied for an unlock the official way, waited a week to unlock the phone again and finally flashed twrp, magisk and mi-globe Rom.

Wait, so you had the 'Global rom' model? Did they leave the phone associated with the Mi account originally? And where did you buy from?
Just curious because my 'Global rom' model K20 Pro arrives tomorrow. Unfortunately ordered the day before all this stuff came out :/

Sorry if this is a bit newby, but I ordered the same (K20 pro) from ali express, there is no way the global rom is official?
If it's not and the bootloader is unlocked, why is this a problem? Because the find my device won't be working? or is the security compromised if it is?
Is the global rom worse than the Chinese? And if the phone isn't disconnected form the Mi account they used to unlock the bootloader with, arn't I screwed?
Sorry for the salvo of questions..

At the moment there is no global version of the phone. So there is no official global ROM. The global ROM versions currently for sale are using a hacked/modified versions of MIUI. These versions are made by people unknown and could possibly contain malware, etc. which could compromise your security. Probably, the ROM will be OK, but you just never know.
Having the bootloader active unlocked isn't a problem normally and gives you the benefit of not having to wait 7 days. You can flash TWRP and install other ROMs with no problem.
But there are a couple of cases on these forums where people have had things go wrong whilst flashing a fastboot ROM using the Mi Flash Tool. They have ended up accidentally relocking the bootloader whilst also corrupting the system partition. Because they haven't unlocked the bootloader themselves originally, they are unable to unlock the phone again and can't install TWRP to install another ROM.
Some people are now choosing to flash an official ROM and relock the bootloader, to allow them to unlock the phone themselves with their own Mi account. So if they end up in the same position as above, they should be able to unlock the bootloader and easily restore the phone.
However some people, when restoring the phone to stock after messing up, have accidentally relocked the phone. When they've tried to go through the unlock process they have found that the phone is still linked to the sellers Mi account and they are unable to link it to their own account and so are unable to unlock it again.
If you never relock the bootloader, either accidentally or deliberately, then you will not have any problems. But if you end up needing to flash a fastboot ROM, then the Mi Flash Tool default option is to flash and relock, so it only takes a brief lapse in concentration to find that you've got a locked bootloader again. If this happens, I would guess that it's far more likely that you won't have any problems and you are able to unlock it again.

Just be aware that this option also comes with risks. Occasionally some people have found that the phone is still linked to the sellers Mi account, they are then unable to ink it to their own account and so cannot unlock the bootloader again.

Netflix Widevine L1 Lost After Downgrade Android 10 to 9 and Flash persist.img

I tried Android 10 and I decide to downgrade my Mi 9T Pro to Android 9. After downgrade, so many things broken because of persist.img
So, I reflash the persist.img (from V10.3.17.0.PFKCNXM) file and problems solved. I am using xiaomi.eu_multi_HMK20ProMI9TPro_V10.3.17.0.PFKCNXM_v10-9 now.
Netflix Widevine is turned from L1 to L3, so I cant play HD or HDR contents. How can I fix that?

once you have modified the vendor/persist partition (flashing the vendor/persist.img through twrp) there is no way to recover widevine L1 except for having to change the equipment for a new one or with a change of pcba
And if you try to flash using EDL? and then tell us if it is possible to recover the widevine L1

I have a Global device. Unlocked BL and flashed the Indian version using fastboot. Haven't rooted but I have formatted all the partitions from twrp before fastbooting the indian rom.
Problem is now I cannot download Netflix app from the Playstore and figured also the playstore "Device is not certified" there in settings.
I want to know this is common and there's no way to get Widewine L1 when BL is unlocked? Or is there a possibility if I go back to the official Global rom and lock it?

Just flash magisk and safetynet patch module, then delete play store data. You can install Netflix now.

Just wondering, what are other disadvantages aside from loosing L1 ? I also flashed my persist image on A3 due to downgrade and sensor problems. Will service center be able to flash to restore it? Cause the phone is running fine on anything else

Same Issue with me. Any progress on your situation OP?

Maybe you should have done some research before doing something that stupid. Flashing persist.img is guaranteed to make you lose l1 permanently.
