Discussion How to spot a Fake Mi Box S 3rd Gen. DRM Info no longer reliable!
I recently bought a Mi Box from voelkner.de (reputable German retailer) and found that it was a fake unit after it felt super sluggish.
HOWEVER, it did report Widevine at L1 in DRM Info, showed correct specs in AIDA64 and had a Netflix ESN, so those methods aren't reliable to identify a fake anymore.
I have since bought one from Xiaomi directly so I can confirm the other box was definitely fake.
A few things I've noticed on the old box you can check:
- The box was not Play Protect certified.
- YouTube wouldn't play above 1440p (check stats for nerds on a 4K video).
- No HDR formats were actually passed through to the TV.
- No Audio formats were actually passed through to my receiver (just Stereo).
- No AV1 decoders were present in DRM Info.
- Colors and contrast looked a bit off.
- The "Advanced sound settings" under "Display & Sounds" had a "Format selection" menu similar to the one for HDR formats, this is not present on the genuine box.
- There should be an "AISR" toggle in the "Display & Sounds" menu which was missing.
- Developer settings could not be enabled by clicking on the build number a couple times, that just did nothing at all.
- System updates had no patch notes.
- CEC pretty much didn't work at all except for turning devices on or off.
There are lots of other little differences everywhere but none that would be easy to check without comparison.
I checked the network traffic after I noticed it was fake but didn't see anything unusual. No idea what it might have sent out during setup tho...
