My Widevine L1 is L3 (Persist Backup Restore) - Asus ZenFone Max Pro M1 Questions & Answers

Will not work, flashing Q firmware on unlocked BL wipes DRM keys. Persist backup from some other phone will not restore Widevine to L1. Only one option - lock your bootloader with Q beta 2, go to service center, act dumb and say that you cant play Netflix HD after update. Hopefully, they reflash and restore it (Reinput of L1 requires authenticated and secure environment - Service Centre PC)

The right way to get back DRM keys if u unlock the bootloader for custom kernel

WHAT YOU WILL ONLY NEED:
- Windows 7/8 and Flashtool.
- .77 (KitKat) Firmware
- .690 Firmware
- DRM LP fix in your SD card (DRM Function Restoration for Xperia Lolipop V2)
- Androplus LP ADV Kernel (I used Z3_ADV_stock_LP_v2)
- THIS GUIDE WILL RESTORE THE DRM KEYS FOR THE SONY FEATURES TO WORK AGAIN(CAMERA X-REALITY ETC...)
NOT UR ORIGINAL KEYS,
Be sure to have the LP DRM FIX in your SD card prior to flashing stuff.
- If your Bootloader is UNLOCKED, LOCK IT (Relock).
- Don't turn it on. If somehow it turns on, hard turn off it by holding VOL UP and POWER until it vibrates 3 times.
- Flash the .77 FTF (Flashtool).
You're back to .77 (KitKat)
- Let it boot till the language selection screen.
- Power it off.
Now you will be going to Lollipop with old TA features, plus a custom kernel so you can use Recovery.
- UNLOCK your bootloader now and:
- Flash the .690 FTF checking the "TA" box. Which means you are EXCLUDING the TA partition from .690 in order to keep the .77's. This is where the magic lies!
- Right now, you are already on Lollipop.
- Right after flashing it, flash the Androplus ADV LP kernelV2 (get it from the Androplus kernel site). That means you are going to get Recovery functions.
- Right after flashing the kernel, access the Recovery screen (holding VOL UP/DOWN when the Z3's led is purple) and FLASH the DRM Fix which should be in your SD card.

Same question here. It is not clear from the first post whether this restores DRM after losing it.
I'm guessing it will work without original backups as there is no part of the tutorial where you restore from a back up. Looks more like a return to stock from any state.
Not that I'm an expert, last Sony I had was a Z1.

I'am not sure if I got this right, please correct me if I'm wrong:
So using this method I will end up with a custom kernel with custom recovery and still got all Sony DRM features that are usually lost when unlocking the bootloader. How exactly does this work? My guess is that the TA partition is not deleted directly by unlocking the bootloader but when booting into Android by the CredentialManagerService. And this hack simply prevents the CredentialManagerService from deleting the TA partition. Am I right?
Edit: I think I got it wrong. This will only restore the Camer and Display features, but not Miracast. Am I right?

I did this procedure and it seems to have worked. I had some trouble with flashing when the bl was locked. I had to keep it unlocked the whole time. I had to flash several times due to some error messages in the flash tool.
After doing this can I flash a different LP customization (the US one) while keeping the TA information or do I have to downgrade to KK first, then go back to LP, doing this whole process again?

Really? On which devices? How exactly?
And I have a question about OP.
Can I change the order the backuping TA partition in TWRP?
So may I make a backup from locked BL and TA before I unlocking my BL? Then I unlocking and making backup from unlocked TA or I just can make in your order? (Unloking - > making backup from unlocked BL -> relocking -> making backup from locked BL)
Thanks in advance.

You'll need to flash a stock rom and wipe everything in the process.
I had the same problem and flashing using the flashtool with all wipe options checked didn't fix the problem. Any other ideas?

I would assume that relocking it without the DRM keys has broken it. To rewrite the TA backup img to the phone you have to use flashtool version 922.3 If I was in your position with or without a drm backup I would try using that version of the flashtool to flash a FW and try the relock procedure again to see if it makes a difference. Have you unlocked it again to see if it brings the camera back?

Ok I unlocked the device again using Sony Mobile Flasher. I'm now flashing an Android 6 ftf file from the UK. I have the TA backup img but am not sure how to restore it. Apparently the Backup TA version 1 had a restore option in the CMD menu. But all the 2nd version does is backup a TA partition key from what I can tell.
Any help restoring the key would be greatly appreciated.
Edit: Ok now I've booted up without locking the boot loader and the camera is working. So now I should be able to lock the bootloader and have it stay working right? But how do I do that?

Lets see. Download Flashtool version 9.22.3 and download Rootkernel, use RK to create a DK.ftf from your TA.img then flash that using the 9.22.3 version of the flashtool. To create a DK.ftf open a cmd window in the Rootkernel folder and enter flash_dk TA.img DK.ftf.
Thank you for the help.
I was using a higher version of the Flashtool so I found the 9.22.3 version and got that installed. I found the Rootkernel and used it to create a DK.ftf successfully from my TA.img.
I flashed that successfully and rebooted the phone but it didn't work. This also didn't automatically relock the device like I read it should of.
I then started over by flashing the Android 6.0 ftf file again. Then I used the flashtool to relock the device. Finally, I flashed the DK.ftf file one more time.
I just booted up the phone and now the camera isn't working with the same error I had before. I also checked the security menu of the phone and it still says the DRM files are not there.
I'm really not sure why it's not working.
EDIT: See below.

Lets try one last thing. From reading the threads here apparently flashing the DK.ftf is only for those with an unlocked BL wanting to keep DRM functions so places the TA in a location that DRM-fix kernels can pickup. To rewrite the original partition you have to do the following...

CONFIRMATION OF TA RESTORE!
- Unlocked bootloader
- Flashed TWRP
- Pushed TAbackup.img (I renamed it) to /data/local/tmp
- Did
Code:
adb shell dd if=/data/local/tmp/TAbackup.img of=/dev/block/bootdevice/by-name/TA
- Rebooted
- Everything back as it was. Original TA restored and DRM keys all active:victory:

NOTE/EDIT: Due to dm-verity, you cannot restore TA on a rooted phone (Z3+ onwards). It won't boot up. Boot and system have to be pure untouched stock.

...if this way fails then it's time to talk to Sony or just run an unlocked BL permanently.
Flashing DK.ftf isn't enough. You need to make a boot.img with DRM fix as well using rootkernel.

By reset do you mean restore it to "out of box" state? Then you need to restore your pre-root backup or flash stock via fastboot. But at this time locking the bootloader is not possible since we do not have the latest firmware, unless your device has older firmware installed (only the output of "fastboot getvar all" would tell us for sure)

Then you can chose the option that fit's best...
1) Unroot in the SuperSU app's Setting's menu with Full Unroot option. This will remove root but not restore the original recovery, most likely leaving TWRP in place, then boot into the bootloader, start recovery (TWRP most likely) and perform an advanced wipe including caches, user data, and internal storage
2) Boot into TWRP and restore your pre-root backup, then perform a factory reset. This may or may not remove TWRP depending on how you did the backup. If you booted TWRP and performed the backup, it should be essentially back to factory state including stock recovery, if you flashed TWRP first then backed up then TWRP will remain.
3) Restore to stock via fastboot with the latest factory image.
Your choice of which is most appropriate for your circumstances.

After you have unrooted, clear data on Snapchat and then log in again (or uninstall and reinstall Snapchat).
I don't use Snapchat or Whatsapp, but my understanding is that you have to login before you root... if you have tried to login, it remembers you were rooted until you clear data.

Well, that shouldn't be it... but locking the bootloader is difficult depending on what version you are on now. The problem is you must flash a complete factory image to lock and we don't have the latest images.

No I'm almost 99% positive that that's wrong you don't need a locked bootloader to log into snapchat? Where did you read this??
@acejavelin is extremely knowledgeable and will be able to help you with any problem you come across, but you should not need to lock bootloader...anything I find says snap blocks root...and safety net is tripped by an unlocked bootloader. The two don't go hand in hand though. Snapchat doesn't use safety net.
Edit: if you're able to make a backup of a snapchat that is logged in using Titanium backup, and then install that backup onto your phone. Don't know if you have an extra device around though. But really confused as to why reinstalling didn't even work? Is there a chance that the unroot option in superSU did not remove root fully??

About 95% sure... Like I said, I don't use SnapChat, but to my knowledge the SafetyNet API doesn't check the bootloader status on Marshmallow devices, only on devices that shipped with Nougat (not that were upgraded).
There has to be some left-overs from root that are causing it to fail.

I doubt it will help, but you can backup and try it... Most likely something is still in /system, you need to restore your pre-root backup for system and boot and wipe caches. If you don't have that backup then reflash the stock image.
