Extract files from LG Backup .lbf file
# For modern LG backup files use a script from here: https://github.com/Mysak0CZ/LBFtool
# with details from there https://forum.xda-developers.com/android/general/tool-lg-restore-com-lge-bnr-lbf-file-t4053579
# Fair warning, this script was designed for really old version of LGBackup and won't work on with new devices
# So, if you don't get what you wanted, try to use every data carving tools you can get
#
# Also, good person with nickname SEVENTY ONE recommends ExtractJPEG( https://www.gunamoi.com.au/soft/extractjpeg/download.html )
# To, well, extract JPG Images from a backup
# 0. You will need 7-zip context menu "Extract here".

handy print for Arduino
//example:
//multiprint("I = ")(10)("A")()("U = ")(10)("V")();
//result:
//I = 10A
//U = 20V
//
//arguments -- same as Serial.print
//no argument -- Serial.println()

Save some variables across all Arduino resets and most reprogrammings without EEPROM
struct SaveableData{
uint32_t update_counter;
};
struct UploadSafe{
char dummy[64];
uint32_t flag;
//Unless more than 64 bytes of global/static variables
