Hi guys,
After downgrading my Redmi (code name Ruby) from HyperOS to MIUI 14, I lost the Widevine L1 certification and now only have L3, which is causing DRM issues with Netflix, Spotify, Prime Video, Disney+.

During the downgrade process, I backed up the following partitions:

Code:

python.exe mtk.py wo 0x40780000 0x2080000 boot_para.bin
python.exe mtk.py wo 0x2d88000 0x2000000 nvcfg.bin
python.exe mtk.py wo 0x4d88000 0x4000000 nvdata.bin
python.exe mtk.py wo 0x3c580000 0x4000000 nvram.bin
python.exe mtk.py wo 0x3c200000 0x300000 proinfo.bin
python.exe mtk.py wo 0x12000000 0x800000 protect1.bin
python.exe mtk.py wo 0x12800000 0x800000 protect2.bin
python.exe mtk.py wo 0x3c000000 0x200000 sec1.bin
python.exe mtk.py wo 0x13000000 0x800000 seccfg.bin

erased the flash memory, installed MIUI, and restored the previously backed-up partitions to recover my IMEI.
Everything is working fine, except for the Widevine L3 issue.

After reading online, I understand that some keys are stored in the persistent partition, which I didn't back up.

Do you have any suggestions on how to solve this issue?
Additionally, I noticed that I have partitions named

Code:

backup1

Code:

backup2

Code:

backup3

Code:

backup4

Code:

backup5

Could these contain any useful information? How can I use them?
Here is the partition table output:

Go to Settings > Detailed info and specs > Tap Kernel Version for 5 times > Device will enter in to CIT mode > In CIT mode select Security Certificates update > Then click Widevine certification update > and then reboot the device.
If that fails, revert to your previous firmware then retry the Activity Laucher method

Tanks for the reply.
The Security Certificates update is missing under my CIT app. I have testet the latest MIUI and the oldest HyperOS ,both same behavior.

Go to Password & Security > Fingerprint Unlock > Fingerprint Payments. You’ll see two options: FIDO and IFAA. Click FIDO, then tap the Certificate button to update it. Do the same for IFAA. Finally, check if Widevine L1 is active

Have you tried flashing the original build your phone was running on before you downgraded?
