-# nandroid v2.1 - an Android backup tool for the G1 by infernix and brainaid
-
-# Requirements:
-
-# - a modded android in recovery mode (JF 1.3 will work by default)
-# - adb shell as root in recovery mode if not using a pre-made recovery image
-# - busybox in recovery mode
-# - dump_image-arm-uclibc compiled and in path on phone
-# - mkyaffs2image-arm-uclibc compiled and installed in path on phone
-
-# Reference data:
-
-# dev: size erasesize name
-#mtd0: 00040000 00020000 "misc"
-#mtd1: 00500000 00020000 "recovery"

-#mtd3: 04380000 00020000 "system"
-#mtd4: 04380000 00020000 "cache"
-#mtd5: 04ac0000 00020000 "userdata"
-#mtd6 is everything, dump splash1 with: dd if=/dev/mtd/mtd6ro of=/sdcard/splash1.img skip=19072 bs=2048 count=150
-
-# We don't dump misc or cache because they do not contain any useful data that we are aware of at this time.
-
-# Logical steps (v2.1):
-#
-# 0. test for a target dir and the various tools needed, if not found then exit with error.
-# 1. check "adb devices" for a device in recovery mode. set DEVICEID variable to the device ID. abort when not found.
-# 2. mount system and data partitions read-only, set up adb portforward and create destdir
-# 3. check free space on /cache, exit if less blocks than 20MB free
-# 4. push required tools to device in /cache
-# 5 for partitions boot recovery misc:
-# 5a get md5sum for content of current partition *on the device* (no data transfered)
-# 5b while MD5sum comparison is incorrect (always is the first time):
-# 5b1 dump current partition to a netcat session
-# 5b2 start local netcat to dump image to current dir
-# 5b3 compare md5sums of dumped data with dump in current dir. if correct, contine, else restart the loop (6b1)
-# 6 for partitions system data:
-# 6a get md5sum for tar of content of current partition *on the device* (no data transfered)
-# 6b while MD5sum comparison is incorrect (always is the first time):
-# 6b1 tar current partition to a netcat session
-# 6b2 start local netcat to dump tar to current dir
-# 6b3 compare md5sums of dumped data with dump in current dir. if correct, contine, else restart the loop (6b1)
-# 6c if i'm running as root:
-# 6c1 create a temp dir using either tempdir command or the deviceid in /tmp
-# 6c2 extract tar to tempdir
-# 6c3 invoke mkyaffs2image to create the img
-# 6c4 clean up
-# 7. remove tools from device /cache
-# 8. umount system and data on device
-# 9. print success.
