From my previous posts, you can see that I am enjoying the journey of trying to build a custom ROM for the CAT S42G cell phone. In particular, I am building LineageOS 19.1, because that is the version that matches the OTA update that I pulled and extracted with …
Last post we looked at extracting/downloading your OTA zip from your phone. Now, if you have your OTA zip you can use dumpyara to extract it, and then aospdtgen to create a LineageOS tree for it. Here I use my OTA zip which I downloaded (cf1f7c3fa1596c87f045cee1508823c98667fa06.zip) :
