Hi, I purchased an EB200V Pro router along with a fiber optic subscription. The router has firmware customized by the provider. I use this provider only for a month, I'd like to know if I can reuse this router by restoring the original firmware. I tried downloading the latest firmware online, it loads, but the customization remains (for example, the TP-Link logo has been replaced by the provider's). Is there a procedure you can provide to restore the image stored in the router, for example, via TFTP? Thanks.
