system_properties

Magisk resetprop can set varies props including read-only properties(start with ro.), however it will also increase the serial number -- or to be exact, the lower bytes of the serial, let's call it counter -- and used by some apps for resetprop detection.

This system_properties utility works on the database file directly without increasing the serial. I forked the repo, adding some cli options to read/set the serial as well as primitive wildcard support.

Usage

All changes will be gone after reboot, to make it "permeant", set it in a boot script as in Magisk module.

usage: system_properties [-h] [-c] [-l log_level] [-s] [-f] [-y] [-v] prop_name prop_value new_count*
  -h                   display this help message
  -c count             set count(optional)
  -l log_level:        console = 1(default) logcat = 2  consle + logcat = 3
  -s                   print security context(selabel)
  -f                   read property_contexts files to get security context
  -y                   auto confirm for new property
  -v                   verbose mode

• Read a property

  system_properties ro.debuggable

• Set a property value to 1, this will not change the counter.

  system_properties ro.debuggable 1

• Set a property value to 1 and counter to 0.

  system_properties ro.debuggable 1 0

• Keep old value and set count only

  system_properties -c 0 ro.debuggable

• Add a new property with Y/N prompt. Use -y to supress the prompt.

  system_properties ro.new.prop 1

• Read all ro. properties

  system_properties ro.*

• Set all ro. properties counter to 0 to cleanup trace from resetprop

  system_properties -c 0 ro.*

Wildcard support

Supports only "begin with" "ends with" "includes" type of matching instead of regex.

Examples:

ro.boot.* match all properties start with ro.boot.

*.version match those end with version

*driver* match those include driver

all for all properties

Wildcard match can be used along with -c option to set counters, but it doesn't support mass setting value for safety reasons.
