 # flipperzero-lrs-pagers
 FlipperZero Brute force of LRS Pager System from [JimiLinuxGuy](https://github.com/jimilinuxguy/flipperzero-lrs-pagers)
 
+Only the 433 version works in all released firmwares (though it may not work for most/any pagers.)<br>
+For the standard 467 version, you'll need to modify the Flipper firmware. See warning below.
+
+This should brute force all resturaunt IDs and pager ids and alert/beep each one for 30s. Verified that this works at Chilis.
+
+Officially supported frequencies are 300-348 MHz, 387-464 MHz, and 779-928 MHz (from [CC1101 chip docs](https://www.ti.com/product/CC1101))<br>
+Unofficially supported frequencies are 281-361 MHz, 378-481 MHz, and 749-962 MHz (from [YARD Stick One](https://greatscottgadgets.com/yardstickone/) docs)
+
+**NOTE: Going outside the supported frequencies may DAMAGE YOUR FLIPPER.<br>
+Please understand what you're doing if trying to break out of official frequencies.**
+
+You'll need to edit some code and recompile if you want to break outside the officially supported frequencies. ([Hint here...](https://github.com/flipperdevices/flipperzero-firmware/pull/1287/files))
