This firmware can be used to restore factory settings and address software issues on your Stream B1s (s40285) device. Using this ROM, the device’s root directory, as well as any custom software, will be deleted. Additionally, flashing this ROM to your device will replace all of the data in it with factory firmware. As a result, you’ll need to back up your data before continuing.
When backing up data, make sure to include important data such as contacts, messages, and app data. This is normally an essential step before flashing or resetting your phone or tablet, as the data on the device is usually completely erased after the flashing process is done. Skip this step if your device won’t turn on or is stuck at the boot logo.
Before flashing, make sure the device is at least 30% charged. If the flashing process is halted due to a low phone battery, unexpected outcomes, such as serious device damage, may occur.
