Are u sure that my device will not get bricked.

There are no 100% guarantees. I would advise you not flash the update if you’re not willing to take the risk

Hello
Been following up on this conversation. I have the same build and I am downloading now… To follow up on the instructions. I have a question though, what happens when a phone gets bricked?

Reply
Hovatek

Well, if you go through the guide carefully, you’ll notice that it emphasizes backing up your current firmware so you can easily revert (unbrick) if the Nougat update bricks your phone.

I have updated mine, I used the scatter file and updated using infinix firmware updater. I previously saved my data as this method formats the phone.
PS: I installed custom TWRP recovery first. Also, it doesn’t matter your current version as this method installs a fresh version of the OS.

You best flash back your stock recovery if you plan using Tcard. If you’re however updating using SP flash tool then yes, you can untick recovery and flash the rest but there’s a very good chance that the TWRP recovery won’t be compatible with your phone after the update
