[Q] Understanding Meta-Inf folder

[emremutlu]

So i pulled stock system folder and deodexed, zipaligned and signed.

Wanted to try flash it by twrp. So i copied one of custom roms meta inf folder but i get sysmapfile error.

Created certificates with signapk but there is no update-binary and update-script file. So i searched and learnt sth about update-script but what is exactly update-binary do? How can i edit for my rom or create one? can i use one of them with all devices rom?

Btw editing update-script didnt solve my sysmapfile error. Can someone guide me about meta-inf folder? All other articles just tells using another roms meta inf but it simply didnt work for me.

The update-binary file is different from one ROM to the next. For example, a CyanogenMod binary will be different from one in a custom ROM based off stock. In general, look at http://wiki.cyanogenmod.org/w/Doc:_About_Edify for an explanation of what the binary is. You will need to pull a binary from a custom ROM based off stock, preferably from the same version of Android.
