Answer 11 · 2019-10-13T14:23:48.000Z

Next step:

Prepare sd card

Partitions of the card should be set-up like followings.
p1 256MB for BOOT : Do fdisk : W95 FAT32(LBA) & Bootable, mkfs.vfat
p2 640MB for /system : Do fdisk, new primary partition
p3 128MB for /vendor : Do fdisk, new primary partition
p4 remainings for /data : Do fdisk, mkfs.ext4
Set volume label for /data partition as userdata
: use -L option of mkfs.ext4, e2label command, or -n option of mkfs.vfat

Answer 12 · 2019-10-13T15:27:38.000Z

cd out/target/product/rpi4
sudo dd if=system.img of=/dev/<p2> bs=1M
sudo dd if=vendor.img of=/dev/<p3> bs=1M

replace <p2> and <p3> with the partition

Copy
device/brcm/rpi4/boot/* to p1:/
kernel/rpi/arch/arm/boot/zImage to p1:/
kernel/rpi/arch/arm/boot/dts/bcm2711-rpi-4-b.dtb to p1:/

Answer 80 · 2019-11-19T23:29:52.000Z

I havent learn to compile or edit yet. Thats why i follow what you guys are talking about to see if i can learn a bit. Started 1 year ago with my first board RPI3b and didnt know anything about arm, computing, linux or anything. And didnt have anyone at all to ask or talk to about the new world with the small computers and the new OS called linux. So after 4 months of 100% fail missions in linux then i had my very first victory. compiling a u-boot for a armbian OS... which was a automated script (.sh) haha. but then again i learned how to start the script (sudo ./learnlinuxffsnow.sh) all i experienced with small board computing i have learned from forums and youtube and still doing it the day today. So i search for android OS for RPI4 4gb in a compiled and ready to burn image file. Enough of my boring non knowledge history. I have been searching for it every day since i bought the RPI4. Asked on many youtubers comment section for the iso file.... Nothing yet. So thats why i cant wait until the day where i can drop a iso file onto micro sd and start up a android OS. IF android 10 is the version then we make history which isnt completed yet at all in the world. So my father just died and left me a computer which i installed linux on and told raspberrypifan he can use it as he likes, do what he wants to get closer to a final build. So i hope we get there in time before everyone else :)

endline: its friken a huge step for me that i get to know RPIfan in this thread. He is the very first i ever could ask question to and got the help i needed. So cant thank him enough. and i hope this new community here dont walk away even after the goal is reached!
