+# 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"
+#mtd2: 00280000 00020000 "boot"
+#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.
