If you are a Xiaomi fan, you probably know how to update your device manually using the bigota source. This was a simple and convenient way to download and flash any MIUI ROM on your device without rooting. You could also download the same ROM that you were using from the “download latest package” option in the settings.
However, things have changed since Xiaomi introduced HyperOS, a new operating system based on MIUI 15. Xiaomi has closed the bigota source and replaced it with a new one called ultimateota. This means that you can no longer update your device manually using the old method. You may have seen an error message saying “Access Denied” when you tried to download the MIUI ROM from the bigota URL.

What is ultimateota and why did Xiaomi close bigota?
Ultimateota is the new source URL that Xiaomi users can use to download the MIUI ROMs of Recovery, OTA and Fastboot. It is similar to bigota, but with some differences.
First, ultimateota is only available for HyperOS devices, which means you need to have MIUI 15 or above on your device to use it. If you have an older MIUI version, you need to update it first using the OTA method or the Mi Flash tool.
Second, ultimateota is not accessible for all regions and devices. Currently, it is only available for China and India regions, and for some selected devices, such as Redmi 12 5G, Mi 11 Ultra, and Mi Mix 4. You can check the availability of your device and region by visiting the [official MIUI website].
Third, ultimateota does not allow you to download the current ROM from the “download latest package” option in the settings. You need to find the download link manually from the MIUI website or from other sources, such as [Xiaomi Firmware Updater] or [Xiaomi EU].
Xiaomi decided to close the bigota source and introduce ultimateota for several reasons. One of them was to prevent unauthorized downloads and leaks of the MIUI ROMs. Another one was to provide faster and more stable downloads for the users. And the last one was to prepare for the launch of HyperOS, which is supposed to bring more features, performance, and security to Xiaomi devices.
