"Software Install Failed" When updating P9 Plus to L29C636B362

Hello!
I have a P9 Plus that I wish to update from Marshmallow (L29C636B170) to Nougat (L29C636B362), but I am unable to because I keep on getting this message when I try to update...

"Software Install Failed!
Failed to check the update package.
Please download the package again".
I have tried using different firmware versions like B320 but the same error appears.
This phone used to have a custom TWRP recovery, but was returned to stock, and I fully unrooted my phone. I then use the Huawei Updater to send the package to HiSuite and find the firmware using Firmware Finder. I still have an unlocked bootloader however. Am I missing anything?
Cheers,

Try relock the bootloader.
How do I relock the bootloader? I tried using fastboot oem lock to relock but it says that the command isnt allowed.
just simply force update dload of update.app if you are in B170 then use update.app of B170 and force dload by push 3 button same time
Okay, it seems I have solved this question with the help of Mostar088 and itongx. Special thanks to them!
The first problem was that the firmware I had was to old to update to Nougat. I had to install L29C636B202 using HiSuite. This updates the firmware to B202. Updating to B202 makes it capable of upgrading to Nougat. So, I then install L29C636B370 to my phone using HiSuite and Huawei Updater. So far, I'm loving the update and none of my files were deleted, however, this doesn't mean you shouldn't back up.
Cheers.
