This procedure will completly WIPE all your data!
This is NOT to root the FP3
FP3 comes with a locked bootloader. This prevents user to write in /boot, /recovery, /system, /modem & other partitions. Unlocking the bootloader removes a layer of protection, but also allows you to flash a custom recovery, a custom ROM, a custom kernel, or a root script.
This will most probably be needed to root your FP3. So if you will need to root your device, I advise you to follow this guide as soon as you get your phone, as this procedure will wipe all you data.
But, I have no idea if this procedure will void the warranty of your phone. It is possible to revert the procedure and go back to a locked bootloader. Once again, you will loose all your data and maybe the warranty of your phone, do this at your own risks and don’t blame me
So, let’s do it, now that this is stated.
1/ OEM unlocking
The FP3 is giving you the option to manually unlock your bootloader. This is the so-called OEM lock (see at the end for more information).
The first step is then to performed the OEM unlock.
About phone, and hit 7 times the last entries,
Build number, then enter your password. This allows you to access to a new setting menu,
Developer options, in
So, go to
Developer options. Then, select
OEM unlocking. Also select
First step completed, you can restart your phone.
2/ Bootloader unlocking
For this second part, you will need functionals adb and fastboot. You can download them from here (see at the end for more information).
Plug your phone to your computer. On your phone, accept the connection and tick to always accept this device.
On your computer, open a terminal and test the connection:
This should answer something like this:
List of devices attached
Then, you can reboot in the bootloader:
adb reboot bootloader
On the bootloader, you can see the last line: DEVICE STATE - LOCKED
So know, you just have to enter:
fastboot oem unlock
(on Linux you may have to enter
sudo fastboot oem unlock)
Then, on your phone, navigate with Volume + / Volume - to accept (power button). This will completely wipe your phone and at the end of the process (it will restart 2-3 times), your phone will have the bootloader unlocked.
3/ Relock the bootloader
Do the same procedure, but with:
fastboot oem lock
Again, this will wipe you phone.
