Please tell us some basic information before asking for help:

  1. Model Name: ZS620KL
  2. Firmware Version: WW_user_100.10.107.92
  3. Rooted or not: Not
  4. Frequency of Occurrence: Always
  5. APP Name & APP Version (If your issue relates to the app): DRM Info


My Bootloader was unlocked at first with Beta Verizon of Android 10 installed, so sure it would be L3 with bootloader unlocked.

But, then I found a way on XDA to lock the bootloader back by downgrading to Android 9 Pie, from link:


So, this successfully relocked my bootloader and then I upgraded back to Android 10 stable version. Then after upgrading back to Android 10, I did hard reset once. But still when I download the DRM Info App, it still says WideVine L3, with bootloader locked and latest Android 10 Version of the ZenUI installed

Plus here I found one user (dip7g) stating that he did lock bootloader back and got L1 back, but never stated how. Link :


If any one can help me with getting L1 back, it would be great as I would be giving away this cell phone to my little brother, who likes to stream Prime and Netflix a lot. 

I have also attached the Screenshots of the bootloader, DRM Info and About Phone.

Thanks a lot, in advance.
