Alex contacted the seller, who thankfully agreed to help. The previous owner logged into their MI account on a browser, went to the Xiaomi Cloud, and removed the device from their trusted list. Then, on the phone itself, they remotely signed out via “Find Device” > “Erase & Remove Account.”
Frustrated, Alex searched forums. Some called it the "gatekeeper error." Here’s what he learned.
Alex reset the phone, logged in with his MI account, and waited 72 hours (a required cooling period for his model). This time, when he ran MI Unlock Tool, no 1004 error appeared. The progress bar moved—slowly, surely.
He downloaded the official MI Unlock Tool, connected his phone, and followed every guide. But just as hope peaked, a red message appeared:
Alex had just bought a used Xiaomi phone. It was a great deal—perfect hardware, a vibrant screen, but it was tied to the previous owner’s MI account. To truly make it his own, Alex needed to unlock the bootloader, the first step to installing a custom ROM or simply freeing the device.
After 72 hours, Alex unlocked the bootloader successfully. Error 1004 wasn’t a bug—it was a feature to prevent theft. He learned that the error means: “Prove you own this device by using the original account or having it removed properly.”
Error 1004 is Xiaomi’s security mechanism preventing an unauthorized MI account from unlocking a device. Unlike simple password errors, 1004 means: “This phone is locked to a different Mi account, and you haven’t proven ownership.”
He tried the usual tips—rebooting, reinstalling drivers, using a different USB port. Nothing worked. So he dug deeper.
