Brute force gate remote for SMC5326, UNILARM and PT2260 using Flipper Zero, inspired by Breaking Protocol and flipperzero-bruteforce

Only works on UNILARM, SMC5326, PT2260 and others remote that using the same protocol.

Also can read my blog post on how I investigate the gate remote protocol

[ 16bits of DIP switch combinations ][ 9bits of Instruction base ]

Example in Pulse Plotter:

[ 16bits of DIP switch combinations ][ 8bits of Instruction base ]

Example in Pulse Plotter:

Both protocol is similar to the PT-2262 Format (Princeton). More info here in russian

• 150μs high 650μs low represent 0, 550μs high 250μs low represent 1
• Button 1 Instruction: 110000000
• Button 2 Instruction: 001100000

• 300μs high 900μs low represent 0, 900μs high 300μs low represent 1
• Button 1 Instruction: 111010101
• Button 2 Instruction: 101110101

• 300μs high 850μs low represent 0, 850μs high 300μs low represent 1
• Button open Instruction: 00000011
• Button lock Instruction: 00001100
• Button stop Instruction: 00110000
• Button close Instruction: 11000000

Sample raw .sub files here

Using generate.py you can generate all the .sub files to brute force, or you can directly copy the generated .sub files into the flipper's SD card under the /subghz folder

Under 6561 folder got 1 file contains all 6561 combinations of DIP switch, 2187 contains 3 sub files that contains 2187 combinations, and 729 contains 9 sub files etc. (The less the combinations the more the sub files)

To brute force all combinations of DIP switch, simply run the 0_0.sub in the 6561 folder

To narrow down the brute force time, you need to run multiple times (Something like binary search)

For example:

1. Your gate remote is SMC5326 and frequency is 330MHz
2. Copy the folder SMC5326_330 into flipper's sdcard subghz folder
3. Play the 2187/0_0.sub file and the gate opens
4. Under the 729 folder, play the sub starts with 0: 0_0,1,2.sub and see which files opens the gate
5. If 0_1.sub works, then play the sub starts with 1: 1_3,4,5.sub under 243 folder
6. Continue narrow down the combinations until you happy with the sending time of the .sub file

PS: Please test on your own gate or get permission before you test!
