 This is one of the tools used to get the data you can find on my own site [smartphonecombo.it](https://smartphonecombo.it) and [cacombos.com](https://cacombos.com).

+# Run in Docker
+
+Before running 28874Decoder you have to decompres yours 00028874. There are several ways to do this, below you will find some:  
+* `$ binwalk -e 00028874`
+* `$ openssl zlib -d -in 00028874 -out unpacked`
+* `$ printf "\x1f\x8b\x08\x00\x00\x00\x00\x00" | cat - 00028874 | gzip -dc > unpacked`  
+
+Most likely in the future 28874Decoder will be able to decompress automatically.  
+
+After compressionm just run
+
+```
+docker run --rm --name 28874Decoder ghcr.io/HandyMenny/28874decoder [path_to_unpacked_00028874]
+```
+
 # Build Instructions
