My System partition still has 220.127.116.11 on it, and I'd like to reinstall a 18.104.22.168 kernel, without wiping my System partition, so I can switch back to Android.
I've (I think) extracted a kernel image and a ramdisk image from a 22.214.171.124 install image, and I'm trying to create a install image containing just the kernel and ramdisk, and copy it to the Staging partition with dd.
I've created a Makefile to create the blobfile, and (seemingly) successfully created the blobfile, but after I do the dd, and reboot, debian/ubuntu boots as usual, instead of some kind of install process.
I've included the Makefile that I'm using below.
Any idea what I'm doing wrong, or what's wrong with my expectations?
Something I have yet to try is an alternative to dd (such as fastboot or nvflash)
Also, maybe I'd have better luck trying to create something that I could install from TWRP.
kern = zImage bootimg_filename = boot.img blobpack = ./blobpack blob_img = blob.LNX recovery_part = /dev/mmcblk0p4 $(bootimg_filename) : initrd.img $(kern) abootimg --create $(bootimg_filename) -k $(kern) -r initrd.img blob.LNX: $(bootimg_filename) $(blobpack) blob.LNX LNX $(bootimg_filename) install.dd: dd if=$(blob_img) of=$(recovery_part)
