Firmware Finder is an unofficial app exclusively for Huawei devices that lets you download and install the latest official firmware update for your particular device. It is by no means an illegitimate or harmful tool, as the downloaded files are always the ones officially published by the company at a previous date.
Once installed, the app will detect your specific smartphone model and display a list of all possible updates, along with their rollout dates. When a new update is published, rollout is staggered among all users, meaning that there can be a difference of weeks between one device and another, even if they're similar and located in the same country. Firmware Finder speeds up this process.
To speed up the installation, the app uses a proxy to make the Huawei remote verification server think that it's 'time' to roll out the update. All you need to take into consideration is the type of update you install, as a full version of firmware can be installed without any problem (they tend to exceed 1GB), whilst OTAs are partial modifications which require a particular version in order to act as a temporary fix instead of a complete override. For this reason, we recommend always using Full updates.
Firmware Finder is a useful tool that helps people who are eager to update their devices as soon as possible while also resolving any problems related to the delay in deploying new versions of firmware modified by specific service providers.
