Franklin R850 Hidden Features & Tweaks: USB-tethering, Band-selection, & More!

Post by TomsMo » Mon Jun 07, 2021 7:26 pm

I started using this modem two months ago and wanted to compile a guide to all of the tweaks and hidden features I've discovered buried in various dusty corners of the web that may or may not exist by the time you're reading this 8-) .

You will be going into debugging menus containing potentially device-breaking options. Most if not all of these settings are not effected by resetting the modem to factory settings.

MSL Service Code Bypass
Many pages will prompt you for a Service code for access with the following:

Luckily for us this prompt is nothing but a cosmetic webpage element and we just remove it to access the page beneath it. We can use uBlock Origin to automatically bypass it, or we can use the debug tools in-built into most web browsers to do it manually.

For uBlock Origin add the following to your "My Filters" page:
NOTE: These filters will also break the (Normal non-hidden) settings page at http://myhotspot/
Turn off ublock Origin or remove them if you need to go in there to change settings.

Code: Select all

To bypass manually:
1)Press F12 to access the developer Tools(works for Google Chrome and Firefox, likely other browsers as well)
2)Delete the following two elements by right clicking and selecting "Delete element"
3)Edit the div class to be blank, instead of "block-page hidden"

Hidden Service Pages
There are two hidden URLs with various useful options:
  • Enable/Disable certain Bands
  • Adjust Band Priority
  • View Debug Info (RSRP, RSRQ, SINR, Band in-use, etc)
  • & more!
