[Lenovo P11] Stremon:
I tried 3 different regions, they all showed up as certified in play protect, they all were L1 in the drm check app, but the Netflix app always sees only L3.

Can you guys tell me what the Netflix app tells you in the "Playback Specification" menu?
[Lenovo P11] MrCrayon:
Wow, I guess something happened, I have L3 too in Netflix now!

It was probably a Netflix update that broke it, you might try to install an older version.

I know for sure it was L1 around 10 days ago.

@CptanPanic can you check again if Netflix reports L1 and which version do you have installed?
[Lenovo P11] Stremon:
Ok so that's normal, I was afraid my tablet had something especially wrong there :ROFLMAO:

Issue is that older versions will most likely fall down to L3 beside it won't be in sync with Play Store anymore.

On a side note Amazon Prime does work perfectly in HDR, and Disney+ works ok as well but only HD, no Dolby Vision.
[Lenovo P11] MrCrayon:
So I tried the previous Netflix version, 8.12.0, still same problem.

I guess Netflix removed the device from their list.

If @CptanPanic Netflix is still L1 I can see a couple of things to check:

Actual model Xiaoxin vs P11

ROM global vs chinese

Mine are

Xiaoxin Pad Pro

TB-J706F_S620022_210910_ROW

and

TB-J706F_S620150_211226_ROW
[Lenovo P11] Stremon:
Yeah mine is TB-J706F_S620022_210910_ROW too.

I really hope Xiaoxin does something about it.
[Lenovo P11] mardon85:
Are you joking.. They can't even fix issues with their core software let alone a streaming app which isn't even used widely in china.
[Lenovo P11] Stremon:
Well... Yeah true haha

Although with the Netflix app I wonder if it had something to do with the fact that it's preinstalled. Maybe if it gets completely removed from the base ROM it would work? Not sure but I do hope.
[Lenovo P11] MrCrayon:
Lenovo Tab P11 Pro is still in the supported tablet list https://help.netflix.com/en/node/23939

So I'm wondering if this is affecting only the Chinese version Xiaoxin Pad Pro or also Lenovo Tab P11 Pro.
[Lenovo P11] CptanPanic:
Yes I have Netflix L1, but have only had tablet for 2 days now, using latest Netflix apk. I have J716F
[Lenovo P11] Stremon:
Yeah not the same model, we are talking about the J706F model here ;)

I guess you are using the Chinese ROM on yours?
[Lenovo P11] Stremon:
I tried uninstall the preloaded app through adb, install different version, but it's a no go. I do believe that Netflix simply blocks any Android tablet with an unauthorized preloaded Netflix app...
[Lenovo P11] MrCrayon:
The problem is not Netflix app, the app preinstalled is simply an old version.

The fact that you can update through PlayStore means is signed with the same key so it's an authentic app from Netflix.
[Lenovo P11] Aadieu:
Mine has no Netflix preload and won't let me download it from playstore.

Xiaoxin 2021 870/oled, global rom, from aliexpress

What's a safe source to download Netflix apk from?

Also, I get a "device not compatible" issue when trying to find Rakuten Viki from Google Play via "Library" (search won't show it at all), is that the same thing? Any idea of a safe source to load that from?

Amazon Prime video installs but plays in atrocious quality
[Lenovo P11] MrCrayon:
apkmirror.com

You can read my previous posts for a way to have your device certified and solve the PlayStore problems but I am not sure is going to work for your tablet.

Also that method is going to force a factory reset and I think in some cases that messes up the security app for your tablet.
[Lenovo P11] zerosignull:
Lenovo P11 Pro has now gone from widevine l1 to l3

Not being able to install from the store was not an issue for l1 for almost a year? Only noticed after December sec patch + play store patch.

DRM info app shows the tablet has widevine L1 though ... So maybe something to do with the device ID and Netflix? Notice the apps are reporting diff system ids
[Lenovo P11] MrCrayon:
I don't think it's related to updates, you can check also this thread

https://xdaforums.com/t/tb-j706f-p11-pro-global-rom-update-s620150_211226.4388759/

Is your tablet Xiaoxin Pad Pro or Lenovo Tab P11 Pro?
[Lenovo P11] MrCrayon:
I found another people complaining here:

English Community-Lenovo Community
[Lenovo P11] zerosignull:
Xiaoxin pad pro. Seems to be a common issue. Was fine before the update as I was not getting the OTA from November/Dec was toying with sideload but decided not to as Netflix was L1 and tab was also now play certified.
[Lenovo P11] MrCrayon:
I have two tablets both TB-J706F, one updated and one not but I lost L1 in both.
[Lenovo P11] Benson.TW:
I think this is the problem,because my two cellphone system id is the same with Netflix, so they show L1,but tablet system show different system id like your situation.
[Lenovo P11] zerosignull:
Can I ask if the one that has not been updated has had a Google play system update?
[Lenovo P11] MrCrayon:
No, Google Play system update is still March 1 2021.
[Lenovo P11] rookery:
So does it mean after upgrade to firmware version TB-J706F_S620150_211226_ROW,

Netflix will drop to L3

What is the latest firmware version known that Netflix able to stay L1?

Thanks
[Lenovo P11] MrCrayon:
It's not related with the last update, I think is something server side from either Netflix or Lenovo.

Do you still have L1 in Netflix?

I saw the answer in the other thread.
[Lenovo P11] rookery:
So no matter on which firmware, now everyone lost Netflix L1 ?? and cannot restore? ......

Arrrr...... I just brough this tablet because

1). it has OLED and HDR + Netflix Cert......

2). Year End discount @ RMB 1369 (around USD 215) with free shipping, back cover and screen protect

Then NV write to change Regional Code, Flash from ZUI to ROW, Change country code from CN to HK............

Result still no HDR.............i want to cry.........
[Lenovo P11] Stremon:
did you get the 2020 or 2021 model?

normally with the 2020 model you don't need to flash other roms, just change the country code.

for the rest... well let's hope lenovo does something about it :(
[Lenovo P11] rookery:
The one I got is 2020 China Model, that why I need to flash to Global ROM in order to get fully working Google Play
[Lenovo P11] Benson.TW:
So now the problem no change?

Netflix still show L3??
[Lenovo P11] rookery:
Remain the same

Google Play show certified

DRM Info show L1

Netflix still L3, app version 8.14 build 5 40129
[Lenovo P11] Stremon:
Yeah I tried a tons of netflix versions, nothing works.

I am starting to wonder if it was ever L1 on netflix on this tablet :ROFLMAO:
[Lenovo P11] Thystle:
TB-J716F has never been released globally.

So I am quite sure that your rom is not global rom. The global rom of this model not exist yet.

That is why the Netflix is not preload. All global rom Lenovo Tablets have Netflix preinstalled.

You can try other way to install Netflix. But I highly suspect that your system is the main reason.
[Lenovo P11] mdgmr:
I got the p11 pro (Xiaoxin Pad Pro with global rom) today

Same for me Netflix L3

No problem for disney plus in HD and Prime video, and SALTO (french app of streaming) show L1 in their app
[Lenovo P11] MrCrayon:
From the other thread I can confirm this is working to have 1280x720 quality.

I don't know if anyone tried test patterns when L1 was not a problem to see if it was still limited to 1280x720 or if it was better.
[Lenovo P11] MrCrayon:
Sad update (maybe I was not wrong) with 7.120.0_build_7_3558 after a while "Playback Specification" voice appeared and it's again L3.

I have autoupdate off and Netflix is still that version, I am trying now to keep 6.26.1 to see if the same thing happens.
[Lenovo P11] mdgmr:
Thank you very much !

It's working fine for me and I have 1920x1080 quality and Dolby Vision, I don't update to 7.120.0
[Lenovo P11] uai1:
Hello i have preloaded Netflix app and i cannot uninstall it. Only disable it. When i clean cache etc. and disable it the older version still cannot instal it even without disabling app cannot instal it.

Is any fix for that ?
[Lenovo P11] zerosignull:
Can confirm on version 6 I get Dolby vision and 1080p back
[Lenovo P11] zerosignull:
You just need to clear the cache and uninstall updates. This will reset you to the preloaded one. Then download the version 6 APK from the internet and install it
[Lenovo P11] MrCrayon:
To uninstall updates you need to tap on the three dots.
[Lenovo P11] MrCrayon:
I tried again and for some reason Test pattern 3840x3160:60 plays at 1280x720 but other patterns play at FullHD 1920x1080.

@mdgmr @zerosignull how did you test audio to know it's Dolby vision?

Nevermind I saw the notification.

I kept 6.26.1 since yesterday and it's still L1.

I'm going to try to update to 7.120.0 and see if it stays.

Update: 7.120.0 goes back to L3 after a while, I think it happens after playing a movie.
[Lenovo P11] mardon85:
Nicely done everyone. So this is a netflix issue not a Lenovo one?
[Lenovo P11] CryptMan:
Hi, I have the same issue with my P11 Pro.

I have read that some Pixel devices had a similar problem last year, could it be that this is the same?

If you look at the pictures, the wrong device ID that Netflix shows is in the ESN number. Also there you can read L3, thats also not correct.

I have talked to Netflix, they say that this is an issue that the device manufacture had to solve. I feel they fooled my with this advice.

Best regards
[Lenovo P11] CryptMan:
I have tried that. If you go from 6.26.1 (31696) to 7.120.0 (35589) it keep L1 while playing movies and test pattern. Tested from some minutes.

If you directly install the 7.120.0 it is L3 from the first start on.

And if you install 8.0.x after 7.120.0 (with L1) I had to relogin and it reverts to L3.
[Lenovo P11] MrCrayon:
I know that I kept 6.26.1 for one day before updating but on 7.120.0 after a while the app updates something and the "Playback specification" section appears with L3.

Let me know if yours stays, maybe we can figure it out what's different.
[Lenovo P11] CryptMan:
You are right, there happens something in the background.

I have NOT played any movies for about 3~4 hours and now the 7.120.0 downgraded itself to L3.

The app also got a new menu entry "playback specification", after updateting from 6.26.1 to 7.120.0 this entry is NOT displayed.

I really like this kind of "service". You pay a lot of money and they just decide to change what you have to use.

It's like you buy a 80" TV and a week later it shrinks it self to 19" ...
[Lenovo P11] CryptMan:
I'm still diggen around, it could be that clearing the cache triggers the L3 revert in 7.120.0.

Also I found lot's of other people with L1 to L3 on complete different devices.

English Community-Lenovo Community

Android 11 downgrades Widevine to L3 in Netflix

Another issue with Android 11 update, Widevine is downgraded from L1 to L3 in Netflix, and as such the app will only play content in SD now, not HD.

This all reads like nobody cares about the problem 🤯

I also found this, but I din't know if this matters. Netflix 6.26.1 does NOT produce this log but 7.120.0 does.

If Netflix aren't going to fix the problem just use Stremio for full 4k HDR versions of the content. I still have my subscriptions for use on the TV but its up to you. Piss poor really.
[Lenovo P11] CryptMan:
I tried to reflash the device with QFIL ... but now it is more worse. :(

* I lost the serial number, it's now 0123456789ABCDEF

* PlayProtect say: Not certified

[Lenovo P11] alrassgga:
just intall netflix version 7.80

this would solve the problem. and don't update it
[Lenovo P11] alrassgga:
you don' t have to do it. just remove preinstalled netflix app and install older version(netflix 7.80)
[Lenovo P11] Aadieu:
CN rom or ROW?
[Lenovo P11] Stremon:
on ROW with the preinstalled netflix app you can't completely uinstall it (only disable) nor install older netflix versions.
[Lenovo P11] Stremon:
btw I also tried to force install the 7.80 version with adb downgrade, it installs but it doesn't work, still L3.

Edit: Ok I remove what I just said, after clearing the data from the app, it does work!!
[Lenovo P11] Stremon:
For anybody wanting to reenable the L1, do the following;

- Enable usb debugging, and get the latest android plateform tools including adb and android usb drivers.

- Download the 7.80 version of netflix in the usual place, and save it in the same folder as adb

- Open up a windows command prompt in that folder

- type

adb install -r -d netlfix.apk (change the package name to whatever you named it)

- Allow the adb access on your tablet if needed

- Completely clear the app data (very important!)

- Done!

Now it would be interesting to do some tests to see until which version it does work.
[Lenovo P11] MrCrayon:
@Stremon

You don't need to do all that, just tap on the three dots and there is unistall updates.

After that you are back to verion 1.0 and you can install whatever you want.

7.80.0 works well, thanks to @alrassgga for finding it.

7.120.0_build_7_3558 loses L1 after a while so if someone wants to try the versions in between...
[Lenovo P11] Stremon:
As I stated in previous posts, in my case it wasn't possible, as the preinstalled version was higher than 7.8, so any lower version failed to install, no matter if I uninstall updates or not.

Remember that my tablet's netflix was already L3 out of the box (without any app update or anything) ;)

Plus it doesn't cost anything nor have any risk to install it that way.
[Lenovo P11] MrCrayon:
That's really strange...

My tablet was L3 out of the box too and could not find Netflix in PlayStore because "Device is not certified".

I solved that changing region from CN to IT.

If you have a stock global ROM you need to have the same preinstalled Netflix version plus even with adb you cannot uninstall a preinstalled app in system you can only disable it.

If you go on Settings -> apps -> Netflix and uninstall updates which version do you have installed?
[Lenovo P11] Stremon:
I said Netlfix L3, on the og preinstalled version, not tablet L3. And that was even after changing the region.

That was why I made this thread in the first place, remember?

I think you missread some informations of my posts here for some reasons.

The ROM you get from OTA updates isn't necesarrily the same as the full rom that came preinstalled on the tablet, it doesn't always contain the preinstalled apps. I got mine last month and it was already preinstalled with a quite recent ROM.

I never talked about uninstalling the app as adb can't do that, if you know a little bit about abd apk install you'll see that I used the command to force downgrade the app to the apk file version, not uninstall it.

You can't uninstall a preinstalled ROM app, but you can change its version without issues ;)

I don't remember which version I had exactly, but it was a recent one for sure, as forcing the install of older 7.XX versions didn't work (whereas updating to any newer ones did work).

Now the my version of the preinstalled app is 7.80 since I replaced it, so I can't tell which one it was before anymore.

My point is that if you can't downgrade to the 7.80 because the version that comes preinstalled is more recent, just follow my guide.
[Lenovo P11] MrCrayon:
Yeah my bad I meant L3 on Netflix, I guess you never saw L1 in Netflix because you got your tablet after Netflix changed something.

Should be the same I already downloaded from here https://mirrors.lolinet.com/firmware/lenovo/Tab_P11_Pro/TB-J706F/

But I am not sure which version of Netflix is included there, I'll need to mount it and check.

Yeah my bad also to read too quickly, actually I did not know you can force a downgrade, good to know.

What I still have not clear is if you ever tried to uninstall Netflix updates.

Sure, if after uninstalling updates the version is still higher than 7.80 yours is a good solution.

Just to add, when I got my second tablet and after changing region I had L1 on Netflix version 8.11.0, that was on January 9.

After that I did not update the ROM and I probably updated Netflix but for sure something changed also server side because the only version with L1 now is far older than the one I had before.
[Lenovo P11] Stremon:
Yeah I removed the updates several times already, they automatically get removed when you disable the preinstalled apps anyway.

I agree something was changed server side, but hey as long as 7.80 works I'm fine with it ;)
[Lenovo P11] CryptMan:
I have a question, I have compared a J606F with an J706F and I found that on my J706F (P11 Pro) the "secdata" partition is empty while the one on the J606F (Non-Pro) has data in it.

But if I flash that 28KiB partition ... the devices does not boot anymore.
[Lenovo P11] CryptMan:
On my P11 Pro (J706F) I can see a property named "sys.lenovo.widevine_security_level" which is set to L3.

On my P11 (J606F) there ist no such property.

Does anyone know how this prop is set?
[Lenovo P11] victormartins:
Recently received my 2020 Pro, and didn't get L1 Netflix with the latest version.

I've been using the 7.8 version for about 24 hours and the status at playback specifications is L1. Dolby Vision working as well

[Lenovo P11] randyj0seph:
Bro you're a life saver my netflix is back to L1
[Lenovo P11] MrCrayon:
I tried from the interface and disabling the app does not uninstall updates, not sure if with adb is different.

So I checked TB-J706F_S620022_210910_ROW and can only find /system/app/Netflix.apk that is:

android:versionName="1.0.0"

package="com.netflix.mediaclient"

I really do not understand how you can have another version preinstalled. :confused:

If you bother to check you could try to uninstall updates from interface and check what version shows up.

It's possible you only disabled thinking it was going to uninstall updates or you did it with adb and that did not uninstall updates, otherwise I have no explanation.
[Lenovo P11] ppr01:

"our technicians have informed me that they have compiled the fix, which has currently entered the testing phase. After our round of testing, our partners need to verify the fix too and if everything goes smoothly our technicians estimate that we could have the new OTA version with the fix ready by the end of the month. They are optimistic that we could possibly have the fix ready even sooner, but it all depends on how the testing goes. I will make sure to let you all know in this discussion as soon as I hear more on the progress."

@ext23

It can run FullHD, you need to downgrade Netflix app to 7.81.1 build 19 35189 or previous

Hey guys.

I also have the Xiaoxin Pad Pro TB-J706F flashed with TB-J706F_S620150_211226_ROW

software version TB-J706F_RF01_211226

Widevine L1 system wide, netflix also recognizing L1 and HDR10 + DV support, but for some reason since yesterday it has been playing SD content. I uninstalled the 7.80 app update, reverted to stock app that doesn't work, reinstalled 6.26 and went to 7.80 again but can't get HD playback.

What's going on?

EDIT: To clarify, my netflix app IS showing L1, Full HD and HDR10 + DV support. I also get vision logo in enabled movies and shows but the image looks SD. Something wrong with netflix? It was fine two days ago.
[Lenovo P11] MrCrayon:
Update from Lenovo Forum

@Octavio_V try to play Test patterns in Netflix to see exactly what is being played, it might be a connection problem.
[Lenovo P11] Octavio_V:
Now this is interesting. I confirmed my gut feeling, it is indeed sub-hd being played, but a resolution a little bit over the SD 480p that would be the limit on widevine L3:

The plot thickens. Isn't this weird? It's maxing out at 540p, which means L1 and DRM isn't the problem, right?

I called netflix about this and they had me stay on the phone for a painful 50 minutes to investigate the problem. They had me send them prints of the download speed, the widevine playback specification thing...the tech support girl then told me it's a Netflix-side issue, nothing to do with my tablet in general.

They also asked about the app version, and I told them it was on 7.80 because it inexplicably downgrades my widevine in later versions. They weren't too keen on discussing that, and I let that slide since posts above mention it's apparently an unrelated issue on Lenovo's side they're already working on an update to fix.

Seems like the L1 thing and this problem are two totally unrelated, different problems after all. I'm stuck with SD on Netflix on this thing for the time being.

The question now is, if Netflix said they're working on it...will this "fix"...be in a new app update? Then am I doomed either way if I can't move past 7.80 for now?

Guess I'll have to wait and find out.
[Lenovo P11] MrCrayon:
@Octavio_V yes that's over the definition of L3.

I just tried and I have same resolution while before I had fullHD with Netflix 7.81.1 build 19 35189, the last version working that I know.

That confirms that they changed something server side because I did not update the app or the system and before it was playing at FullHD.

Good news is that looks like the fix from Lenovo will be out in a couple of weeks max. 🤞
[Lenovo P11] Octavio_V:
I was playing around here trying to figure out this problem and decided to update my app from 7.80 to current version 8.21. After the update through google play it's still saying L1 in the netflix version 8.21, but I expect it will downgrade to L3 as it does with every version I tested after 7.80.

However, while now it's still in L1 I am still getting a max 960x540 on test patterns.

By the way, the previous app version that worked fine, 6.26 no longer works correctly here. Maybe whatever they changed server side killed off older versions?

EDIT, UPDATE: Lenovo forums ppl confirm that 6.26 is dead as well. They report that Prime Video is no longer working on the tablet either, and I have tried and can confirm this.
[Lenovo P11] Octavio_V:
New update from Lenovo forums regarding the 540p problem:
[Lenovo P11] Octavio_V:
Update: Amazon Prime Vídeo ia nos working again after a few days of playback error.

Netflix 7.80 with lá recognized is still playing at 540 tho.

Edit: Nevermind, issue persists...It was playing with hardware acceleration disabled in SD.
