I have been using various ROMs on my Poco f1. I find that in case of some AOSP ROMs, there are weekly/ monthly updates with some fixes and sometimes the major changes are only the latest security updates. Sometimes the ROM is perfectly working without any glitches except with old Google security patch. So my question is if it's possible to make a zip file with only latest Google security patch which we can be used to update the old stable ROMs. I am hoping it should be possible, if so somebody please make a zip file. Also, if it's possible do let me know the procedure to pack such a flashable zip file.
