Hi, i'm currently trying to port CM-12.1 to the Samsung Galaxy S Advance i9070, aka janice, and have problems to make it boot, i think that the problem resides in the initramfs 2 stage system.
After syncing these repos, applied some patches (device/samsung/janice/patches) and maked bacon, i've got a flashable zip, but when i use it, device doesn't pass up from Samsung logo.
What i've analyzed and tried so far:
- From the flashable zip, i've extracted the boot.img, unpackaged it, and in there i found the initramfs + kernel, in the initramfs i see it's content is the same as in $OUT/root, is this the correct behavior?
- In "$OUT/obj/KERNEL_OBJ/usr" directory i found "initramfs_data.cpio". Inside this file i saw the "/stage1" folder, inside of it i found "recovery.cpio" and "boot.cpio", also the "init" script file (the one referenced in the "initramfs_list"). Now, "boot.cpio" have the same content as the initramfs inside flashable zip "initramfs.cpio", while recovery content is the same as "$OUT/recovery/root" dir.
I ve tried replacing this second "initramfs_data.cpio" from the other one in the zip, then repackage it and flash the zip, but the result is the same, have any tip of while can i do?
Also, where can i found some info of these Samsung image system?, i know it's not the same as others devices, but cannot found any good source of info.
For reference, these are de repos that i am using:
And these are the $OUT files on my private server (sorry but cannot post clickable links until ten post...):
Greetings.-
