Unknown / Missing Widevine CDM - Xperia Z2 Q&A, Help & Troubleshooting

With all pie ROM coming in XDA, I picked up my favorite phone again and flash those rom. It went mostly fine, but then I realized that I can't use Netflix (even with older apk).
After installing DRM Info apps, I found that I have unknown Widevine CDM, so it is not even Widevine L3. I expected that I will miss Widevine L1 after bootloader unlock, but I don't think that I will not have any Widevine CDM. I tried several ROM including stock rom, but it won't restore my Widevine CDM.
To be honest I am not sure since when I lost Widevine CDM, but maybe this is a known issue, or anybody else has this experience? I tried to search Widevine in this Troubleshooting forum but can't find anything yet.
Thanks !

Hello!, I see the same issue on all PIE ROMs I tested, the solution i found to have Widevine L3, is after you flash the ROM, flash the RZ Kernel.
But if you have any exFAT card or USB you want to use with Z2 with this kernel, the OS won't recognize the storage, because the lack of support of the exFAT FS on the RZ Kernel.

Thanks, WIdevine L3 worked after flashing RZ Kernel. Seems SELinux is not enforced for RZ, but it's fine for me as this is not my main phone currently (although with Pie ROM, I am really tempted to use it again daily )
Before reading your solution, my workaround is using patched Netflix apk that floating around in XDA and will force HD streaming , but the version is a bit old.
So thanks for your help !!

Max 2 fails SafetyNet, does it have malware?

So I got a Max 2 x829 which came with a case. It's running Android 6.0.1. It fails SafetyNet CTS and Basic Integrity, so does not run Pokemon Go. Is this expected, or did a reseller add malware on the device?
Mine suffers from the same problem. Where did you buy yours?
I wouldn't put much stock in safety net.

What do you mean? Not passing SafetyNet means not being able to play/download some of the best games on the PlayStore. I think it's relevant.
Same here. I'm using cuoco92 ROM. I tried safety net that comes with magisk manager, but it doesn't work. I really doubt that there is malware installed, but I've no idea why it fails...maybe because ROM is rooted?!
Let me think about this... Most people have buy this device from a international reseller shop instead of the official Leeco store or online shop. Makes sense cause I'm pretty sure that most of the users here on the board are not living in China or India.
Every online shop is installing a custom ROM to make sure that as many languages as possible are supported. The most installed "Shop-Rom" is couco92...
As far as we know every Android device that is able to run a custom ROM needs an opened bootloader and especially couco92 comes with the ability to run SuperSU and Root!
If you just search Google for "SafetyNet" you find an official statement why it's not possible to run Banking or
Pay-Apps and why there's no possibility to run games like Pokemon go on rooted devices!!!
So let me think again about this...
Sorry guys but I also don't understand why the hell this device isn't able to pass the SafteyNet check! It must be because of malware or something like this!!!
Sorry for being so damn ironic! Hopefully it's self explaining why I wrote a post like this and you are able to get the informations you are looking for from the text...
Thanks for the answer, albeit the unnecessary sarcasm. Assuming that's true (which sounds quite reasonable) would the original ROM fix the problem? is the original ROM maybe supporting english language? And could anyone confirm such ROM does indeed pass SafetyNet checks? Thanks!
So ended up flashing the last Indian stock ROM. That solved the "basic integrity" check and now I can download from Play Store apps not previously visible. However, still does not pass the CTS check.
I believe such checks are over exaggerated, hackers can hack strongly locked iPhones or anything similar, so it doesn't matter CTS pass or fail as long as you keep your phone fully scanned with reasonable antivirus/security apps.
I think thats because your phone has bootloader unlocked.
This is the reason:
Devices that ship with Google's Play Store and other apps installed must pass Google's Android “Compatibility Test Suite”. Rooting a device or installing a custom ROM prevents a device from being “CTS Compatible”. This is how the SafetyNet API can tell if you're rooted–it merely checks for CTS compatibility. Similarly, if you get an Android device that never came with Google's apps–like one of those $20 tablets shipped direct from a factory in China–it won't be considered “CTS compatible” at all, even if you haven't rooted it.

Heyyo, use the official LineageOS MM ROM. It passes safety net. There's some other ROMs but I'm not sure. I'll try it on Mokee MM build and report back.
RR N fails Safety Net as it is pre rooted and some other tweaks that cause it to fail.
Oh, another reason why it can fail safety net is modem firmware. You might have to revert to a Chinese or Indian or international modem firmware. I don't think developer firmware works for SafetyNet

I can't pass SafetyNet with latest (04/29) LineageOS 13 nightly. I tried with Chinese 23S modem, wipe everything except Internal Storage, and install Open GApps Pico. I still get CTS Profile Mismatch. I tried with it as my Internal ROM under MultiROM, which I believe should be OK. I think it's expected to fail if installed as a Secondary. In any case, I have no particular reason I need to pass SafetyNet, I just thought I'd try. I've read that on newer Android devices, an unlocked bootloader can cause SafetyNet to fail (unless kernel is patched). I didn't try re-locking my bootloader so that could be it.
Heyyo, hmm well I tried ASOP based DU rom but it failed too but then again I'm using MultiRom as well so I'm unsure if that messes with it since it's a custom boot.img which I think is part of the SafetyNet check...

Can I flash magisk on Openkirin (Omni, resurrection remix) ROMs?

I have the 10" Wifi M5 (Chinese version c00), and finally realized that it will never get widevine L1 so I decided to unlock the bootloader and install a custom ROm. I've tried Resurrection Remix beta 3.1 and the lastest OmniRom which should have widevine L1, but unfortunately i still can't get it.
So my next step is installing Magisk to try and see I can pass safetynet. Just wanted to know if anyone has installed it on an OpenKirin Rom before I try it?
Thanks.

I was just realizing that actually as well, i have a Chinese one too and noticed no L1. If you didn’t have L1 on stock, then you won’t get it under OpenKirin either, as the keys need to be baked into the hardware. I think Huawei only did that or enabled those for the Euro C423 models, but not on Chinese C00.
What stock ROM version were you on when you decided to unlock the bootloader?

I'm on 171. Is there a way to rebrand the m5 to another region? C423 seems to be the only good version. The US variant doesn't seem to have 5ghz wifi.

Not afaik. Didn’t see any success stories of people successfully doing that.

Questions for LineageOS support on S9+

Hi guys,
I think those questions are not new but i not find up to date and really complete thread for this.
I want to run with lineageOS on my S9+ like my old OnePlus One.
I read many threads about camera. It use a closed software but with GCam port what fonctions are break ? aperture OK ? Gcam can run without google play service ?
Others features are breaks ? (i know for samsung software like knox, i mean hardware features like VoLTE)
On Lineage, i can use full encryption and after update OS with TWRP (twrp have no problem for decrypt phone and apply update ?)
Thanks o/
The gcam port is working but the flash is still buggy.

all camera hardware features works ?
edit : i have exynos version if that change something
Yes the camera works and the video recording..but definitely not as good and stable as the touchwiz stock camera...
Thanks for your response.
And for others features like VoLTE, you know if it's OK ?

Most Stable ROM w/ Android or Other OS?

I'm thinking of picking up a NIB H850 G5 for dirt cheap.
I'd like to update to the latest compatible OS for security update reasons, however, require 100% working, and 100% stable OS. I'm going to be using the G5 Cam Plus accessory as well.
What ROM would you recommend? I don't want to use a finicky ROM as I like my devices rock solid for daily use. Thanks!
For a 100% working device, you only choiche is stock Oreo. Unfortunately, all Lineage builds have problems with IR and VoLTE. Plus, by using a custom rom, you won't be able to use LG Camera software (which is, in my opinion, far better than any other, especially for filming).
By the way, if you agree with losing these functionalities, the best rom you can get is Lineage 16, with android Pie.
re
.hi, i use custom rom 16 which u mention and my camera wont work at all. not only lg camera. also flash is not working/
Thanks for the info guys.
Suppose rooting and keeping stock would be wise then.
Is it possible to root with the latest updates or did LG/Google lock it down? Ie: do apps, like payment apps and Netflix, still work on rooted devices, or is it SOL if rooted? I've been out of the loop for a while
In need of a system wide ad/data blocker since the next phone plan I'm getting has a hard limit.
Cheers!
Rooting still works on H850 using Magisk. In stock Oreo, Magisk breaks the flashlight function. To restore it ad have a fully working phone, you have to flash MK2000 kernel after Magisk. Banking apps work well if root is hidden using MagiskHide. I'm not sure about Netflix, as I've never used it.
You can install whatever data blocker you want. I have installed AFWall+ and AdAway, and they work as they're expected to do.
Stock oreo 30c + magisk + mk2000 kernel is the way to go. Its fast, reliable, good battery life. No irritating bugs like volte and wifi calling not working.
I use adaway and i have added the energized blu go hosts file-

This is the route I'd like to go. Unfortunately, LG couldn't be bothered to release Oreo for my device (RS988). Never again, LG.

Widevine L1 with Root now possible as it seems

Hi,
I just noticed that on my rooted (Magisk 23) and therefore bootloader-unlocked device Widevine L1 seems to be active according to DRM Info.
I always thought this to be impossible. OOS 11.0.2.1 fixed some Widevine issues. Is it possible they fixed too much?

I'm not sure about updating to the latest 11.0.2.1 from an older version in an B/L unlocked state (as i haven't tried on my device), but I do know that some people (with locked bootloaders) Lost L1 after updating to 11.0.2.1
I know with the previous versions of OOS11(other than 11.0.2.1), I had to keep the bootloader locked for upgrading from A10 to A11, then I could unlock bootloader and still keep L1. It's nice to know that I may not have to repeat this process if/when I decide to upgrade to A11.

So you mean they should have fixed the error of not licensed devices getting L1 or an error where legit L1 devices were downgraded to L3?

I have seen a lot of users (I think it's mostly 7T devices) that have actually lost L1 with the latest update, even with locked bootloaders.
OnePlus recently stated that their next update is suppose to fix the L1 loss on locked devices, but I would take that with a grain of salt. They've been messing up hard with OOS11 on 7/T/Pro devices.
Aren't unlocked devices supposed to be bound to L3?

You would think yes, but not on OOS11. L1 sticks regardless of the bootloader state.
Do you have any source for that?

Sorry I should probably correct my posts. I don't know if OnePlus ever stated that you will get L1 with an unlocked B/L on OOS11 (I don't think they ever would). As you have stumbled across it with your device, and I know it works with my device as well (and many other 7T/Pro's) since the very fist release of OOS 11, we are somehow able to keep L1 with the B/L in an unlocked state.
