If you want to smartly manage update types of operations on your Huawei P9 then you first have to learn a basic Android operation: rebooting into fastboot mode. What is fastboot mode, how can be reached on the Huawei P9 and what can you do once you are in the desired mode are the info which will be detailed during this step by step guide.
Just like the recovery environment, the fastboot mode is there by default. All the Android powered devices can be rebooted into fastboot mode, though on some OEMs you will have the fastboot mode named differently – for example on Samsung we discuss about the download mode instead. The best is that entering this environment is easy and safe – you will be able to complete the reboot sequence on your Huawei P9 within seconds. Also, the reboot sequence is official as it is supported by Huawei and by Google: no, you don’t have to use risky or complex apps and programs and no, you won’t lose your phone’s warranty while using the steps from down below.
The fastboot mode is usually associated with update operations. In fact you can use this environment on different other procedures such as: unlocking the bootloader of your Huawei P9, installing a custom recovery image, flash a .zip file, downgrade your phone back to stock Android OS and so on. And of course, yes, though fastboot mode you can manually update your Huawei P9 with stock Android ROMs.
Reaching fastboot mode on the Huawei P9 can be done in the same way, by using one of the methods from below, regardless the state in which your phone is found in a certain moment: it can be rooted, locked, running on stock or on a custom Android OS, installed with a custom or with the stock recovery image, running on a locked or an unlocked bootloader and so on – thus, this tutorial is a general guide that can be used anytime you need to (that’s why a good idea might be to bookmark this page).
You won’t risk anything if you access fastboot mode. However, if you decide to complete a further operation by using this environment, before doing anything else you should first backup your Huawei P9. This is an easy to perform operation as you can save everything by syncing your personal info with your account, you can use built-in cloud storage platforms and you can even download free distributed apps from Google Play. In that manner you can save contacts, call logs, text messages, internet settings, IMEI / NVRAM data, market apps, saved passwords, calendar info, images, videos, audio files and even the EFS folder.
One last thing: charge your Huawei P9 if the power left is currently lower than 40%. The reboot sequence is battery consuming and if the power is low your phone might get switched off in the middle of the fastboot operation. If that happens your phone might get bricked – different software related problems might be issued.
