Hey Xiaomi.eu Community,

I'm at my wit's end with a bizarre and incredibly frustrating Google Account issue and completely unhelpful support. I'm hoping someone here might have experienced something similar or have some insight.

The Problem:

I recently flashed my Xiaomi Mi 8 Explorer. My initial flash was to MIUI V11. After realizing it was outdated, I performed a clean flash to MIUI V12.5.1.0.

The result is that two linked listings for the same phone are now present in my Google Account ("Mi Phone" and "Android device"). Renaming or unchecking one affects the other. The listing associated with the older MIUI V11 install ("Android device"?) doesn't respond to Find My Device but still shows as active. This old install cannot be removed through standard Google Account device management.

The biggest issue is that my current phone (running MIUI V12.5.1.0) is never recognized as a trusted device. I NEVER get Google Prompts for 2-Step Verification, and the "Trust this device" option is completely missing during sign-in attempts, even on the phone itself when accessing sensitive Google settings.

What I've Tried (Extensively):

  • Removed and re-added my Google account multiple times.
  • Reflashed my phone.
  • Factory reset my phone twice and set it up as new.
  • Cleared cache and data for all relevant Google apps (Play Services, Store, Framework).
  • Revoked access to both device listings from my Google Account on a computer.
  • Followed all the generic "remove untrusted device" steps from Google Support (which don't work because the duplicate is linked and unremovable).
  • Ensured 2-Step Verification is enabled (it is!).
Google Support Experience:

My interactions with Google Support have been incredibly frustrating. They keep providing generic troubleshooting steps that are clearly not addressing the unique issue of the linked duplicate device and the missing "Trust this device" option. They seem unable to grasp that this might be a server-side issue with my account's device registration stemming from the two separate installs.

My Questions for the Xiaomi.eu Community:

  • Has anyone else experienced a linked duplicate device listing in their Google Account after flashing a Xiaomi device and installing different MIUI versions?
  • Has anyone encountered the "Trust this device" option being consistently missing after a clean flash and Google Account setup, especially after migrating from an older MIUI version?
  • Could the fact that Google registered two separate installs (V11 and V12.5) be the root of this linking issue?
  • Are there any specific settings or workarounds within MIUI that might be relevant to device trust or Google Account linking?
  • Has anyone successfully resolved a persistent Google Account device issue that seemed to be on Google's server-side? If so, how?
I'm really hoping someone here has some insight or has faced a similar problem after flashing. The inability to trust my primary device is a major inconvenience and security concern. Any help or suggestions would be greatly appreciated!

Thanks in advance!
