When i try to update my RT-AC5300 with RT-AC5300_386.1_0.trx, i receive this error:

Invalid Firmware Upload

I'm alone??

@spouliot welcome to the forums. We are all alone (here, there, and everywhere).

You may need to try a few times to get it to 'take'. Test also with different browsers and different PC's, if possible.

If that doesn't work, then the link below will be sure to accomplish what you want to do.
