* What is Nandroid Backup v2.0?
Nandroid Backup is a set of tools and a script that will enable anyone who has root on their G1 and has the engineering/dev spl bootloader [1] (or has a dev phone) + a recovery image with busybox and adbd running as root [2] to make full system backups. These can then be restored using the fastboot [3] commandline tool and your phone in SPL/bootloader mode (hold camera + power). This allows you to create regular backups of your entire phones NAND flash so that you can restore a backup when something breaks. Its backup method works on a level that allows you to completely break, wipe or corrupt any or all partitions and still restore the phone to a working state within a few minutes. This works great for those who use their G1 for normal activities but also want to test their ideas which might break the phone, or when not having an extra G1 to keep purely as a development phone.
* Requirements for use
- Android G1 phone in recovery mode with busybox installed, including appropriate symlinks to at least tar and md5sum, as well as 'adb shell' support running as root. I recommend using JesusFreke US RC30 or UK RC8 v1.2 recovery image. You can flash the RC30 v1.2 recovery.img on your G1 if you don't want to bother constructing your own image. Of course you are free to use your own recovery image and it will work if you set it up correctly.
- dump_image-arm and mkyaffs2image|mkyaffs2image-$ARCH compiled in the current dir, as well as root on a linux/mac (POSIX) machine for constructing system and data images. root is required because the uid, gid and file permissions need to be preserved while extracting and creating the yaffs2 images. You are free to run the script as a normal user and then run the appropriate commands yourself as root; the commands are printed when you run the script as a regular user.
If you don't trust the provided binaries, you are free to compile them yourself. The source for the tools are included. For dump_image, edit nandtools/android-imagetools/Makefile so that you use the proper cross compiling gcc. For mkyaffs2img, just running make in tartools/yaffs2/utils/ should give you a binary. You are on your own in getting stuff compiled, but it should be easy to figure out from the Makefile.
* How to use this (the easy part)
Just boot your phone in recovery mode with the correct recovery.img (one that has adb shell as root + busybox installed with symlinks to tar, md5sum etc) and connect it to your pc/laptop/server. Then run the nandroid.sh script. If something is wrong or missing, it will tell you.
* What about restore?
If you have the dev phone or have root on the G1 and flashed the engineering/dev bootloader, then you can power on your phone while holding camera to get into the bootloader/SPL. It should then show some androids on skateboards (if not, you don't have the engineering/dev bootloader). Plug in your USB cable and push back until it says FASTBOOT instead of Serial0. Now you can fire up fastboot flash {partition} {file.img}.
Fastboot itself is part of the android SDK. If you download and compile your own mydroid build, it should sit in mydroid/out/host/linux-x86/bin/fastboot Perhaps in a future version I'll include a restore script, but for now I don't see the need.
One tip, if you are in fastboot mode on your phone and 'fastboot devices' doesn't show anything, try as root. You might need to edit your udev setup to allow your user to access the phone's usb device (which is different from the one you're in when in recovery or normal boot).
* Where's the source?
Sources are included. They are copies of the Android sources with various changes mostly made by Brainaid.
Everything in the zip is also also available through subversion:
svn co http://svn.infernix.net/nandroid/
Note that I DO NOT recommend checking out the latest revision unless you know damn well what you are doing. No guarantees if you play with fire. At the very least do diff against the latest released version.

How to Restore your phone on a Windows PC using a Nandroid backup
I am going to assume you already have a Nandroid backup created on your SD card using JF 1.31's recovery Alt-B feature. The backup will create a folder called nandroid on your SD.
What you need:
The Android SDK:
Fastboot Windows Binary in this post:http://forum.xda-developers.com/showpost.php?p=3083753&postcount=1
From your Nandroid backup you need three files:
data.img
system.img
boot.img
Steps to restore your phone
1) Put the files Adb and AdbWinApi.dll from the tools folder in the Android SDK into C:\WINDOWS\System32 folder on your PC. Substitute the correct drive letter if windows is not installed on you C: drive
2) Put the Windows Fastboot.exe into the C:\WINDOWS\System32 folder on your PC
3) Create a folder on the C: drive of your PC called android. The path should be C:\Android.
4) Copy the Nandroid backup files data.img, system.img, and boot.img from your SD card to the folder called Android you created by mounting your SD card as removable disk.
5) Unplug the USB cord and power off your phone
6) Power up your phone by holding CAMERA+POWER, you should see three androids on skateboards. If you don't see this go install the Engineering boot loader
7) Plug the USB cord back into your phone and press back. The screen on your phone should say fastboot.
8) Make sure your pc is using the correct driver. Open the device manager on your pc. It is helpfull to have all other USB storage devices besides your phone unplugged for this part. Look for a USB Mass Storage device in the list of the USB devices. Right click on it and update the driver. Pick the option to browse for a driver on your pc. The driver is located in the Android SDK your downloaded in the folder called usb_driver. If this is done right you will now see a device called HTC Dream
9) Press start, go to run and type cmd (If you are on Vista just type cmd in the search box and hit enter). The command prompt will pop up.
10) Type cd C:\android
then enter the following commands:
fastboot flash system system.img
it will say Sending, then writing and say OKAY if it was successful
then type
fastboot flash userdata data.img
wait for the second OKAY and type
fastboot flash boot boot.img
wait for the second OKAY and type
fastboot reboot
Your phone should now be restored exactly as you had it when it was backed up.
This sounds great! I just recently used the other script to make a backup, but this sounds like it's been a bit more polished
I attempted to compile the yaffs2 utils under OS X 10.5 and I encountered a problem during linking:

ld: absolute addressing (perhaps -mdynamic-no-pic) used in _process_directory from mkyaffsimage.o not allowed in slidable image

Any thoughts? I'm heading off to google to figure out what a 'slidable image' is.
-jwb
No idea, and I don't have access to a mac. You could change the makefile and skip compiling of mkyaffsimage, you only need mkyaffs2image, but you'll probably get similar errors.

Google seems to imply its a common issue, possibly solved in a later XCode rev.. We'll see how that pans out.
mkyaffs2image on mac
It built just fine for me when I did the whole mydroid build. It's in out/host/darwin-x86/bin.
Is there some way to mount the yaffs2 image, though? Does one need to do the kernel patch etc on a linux box and then use loop?
Wow this a awesome. Thanks for all the hard work everyone.
you are are ridiculous.....ly good!
so you telling me if we have root and jf's modified rc30 v1.2 and be brick our phone, there's another quarter in your pocket after you die (game over) and you can start a whole new game?

If you have flashed the engineering bootloader (the androids on skateboards appear when powering on your phone while holding camera button), yes.

This didn't work at all.
What I don't really get is that it continues at all, if the device isn't connected it should not even start.
It's a bit hard to tell because I don't have a mac here. Please run the following commands on your mac and post them:
[code]which adb
adb devices
BLAH=foo
echo "without $BLAH"
echo "with ${BLAH}"
I'll look at this soon, should have access to a mac sometime in the next few weeks

Well the script is supposed to check for a device and stop when theres a problem.
also if this can happen at all then other things might go wrong on mac too. I think mac requires bash variables to be called like #{VAR} and doesn't handle $VAR for some reason.
update on mac issues
OK, it seems it was all a problem on my end -- didn't have the correct set-up. I now have the appropriate recovery image (thought I did, but I guess I didn't) and it seems to work, except for this:
Code:
Comparing md5sum...parseopts.c:76: setup_check: fopen '--status': No such file or directory
The images and such now have non-zero filesize, though. That's an improvement over before.
yeah i've gotten some more reports. will make it mac OS X compatible soonish
I can't seem to figure out how to get this to work. If someone who knows linux can IM me, that'd be great. (or is there a way to do this on XP?)
AIM:adventninja
Thanks in advance
Does this also back up radio and htc secure nand partitions?
tranks
backed up successfully.
for those who get errors in the script.
i assume you have installed modiffied recovery image + jesusfreke's rc30v2 and
before running the script check this.
this steps involves having linux i dont know how its done in windows maybe its the same i dont know.
1: disconnect usb cable
2: check that you have adb program in your path, eg: /usr/bin/adb
if you dont know what adb is, adb is a program to comunicate with phone via usb (its not the same as transfering files between pc and g1),
adb program is found in android-sdk-linux_x86-1.0_r2, unpack it, and copy adb to your path, just google and find latest android sdk.
once you downloaded sdk unpacked it and copied the executable file adb to /usr/bin go to next step.
3: boot the phone into recovery mode ( power up the phone and holding "power + home" keys and a triangle will appear on its screen.
4: in your pc open konsole, su root, and plug your USB G1
5: type adb devices
if the response to this command is "HTC G1 bla bla.. found.", then you are ready to execute the script, it will no give errors and you will backup its contents.
if you dont see HTC G1 words, then its likely your phone was detected as "USB MASS STORAGE", and we dont want that. we need that its detected as a "HTC DIRECT ACCESS DEVICE".
a: control +c
b: killall adb (this is important)
c: unplug USB, plug it in another port,
d: go to step 5
hope it helps.

hey infernix, did you happen to get a mac version of this together? thanks!
I'm trying to play around with the hosts file through adb. I'm new to android from WinMo and trying to learn a few things but couldn't figure this one out.
when I push a new hosts file with:
Code:
adb push hosts /system/etc/hosts
a few seconds later the evo restarts and reverts back to the old hosts file with only localhost listed in there.
I ran into one tutorial that showed the person booting into recovery mode and moving the hosts file from the sdcard to the etc dir:
Code:
adb shell
mount /system
mount /sdcard
cp /sdcard/hosts /system/etc/hosts
exit
Does the hosts file have to be modified via recovery mode or am I doing something wrong by pushing it?
Any help or input is greatly appreciated.
Incase you dont know yet in the hundreds of post all over the rooting threads system is only writable in recovery. /system is nand locked when the OS is running.
ah ok. thanks.
now I'm a bit confused.
when in recovery mode after invoking
Code:
adb reboot recovery
I can't start a remote shell. I get the following error message:
Code:
D:\adb shell

Hi guys!
I suppose the thread was close so I hope it isn't wrong posting here.
after carefully reading the 12 pages of http://forum.xda-developers.com/showthread.php?t=884093&page=12
I'm still getting the "mismatch md5" error, it's really frustrating...
These are my procedures:
(right now I'm using MIUI 1.4.29 + EN Pack1_2.3) and CWM 3.0.1.4, and of course the SNS is unlocked.
-Download the stock rom "twice" from the two links from mediafile posted in the first thread. just to be sure they are the same files. First open the zip file with 7zip and run the "test" no error. Second test, compare md5 hashes from the 2 zip files downloaded --> matched. Third, extracted them (PC) and open the nandroid.md5 files with notepad++ and verify every files hashes -> matched
-Booted to recovery --> CWM 3.0.1.4 --> mounted usb storage
-extracted directly from the zip file to maintain the "clockwork\backup\2010-12-22.21.06.07" directory structure.
-unmount. restore --> mismatch md5
-open the zip file manually drag the clockwork to sdcard (extract and copy) --> unmount --> restore from 2010-12-22.21.06.07 --> mismatche md5
-deleted the previous folders, and create folder one by one manually the drag each file inside --> mistmach md5
Those are the steps I tried, I'm running out of ideas.
googled the issue and couldn't a single concrete answer to this problem... My guts is telling me is a directory bad naming, but I'm keeping it just as it is.
any help is appreciated!
Thx in advance
be sure you've got busybox
Code:
adb shell
cd /sdcard/clockworkmod/backup/[COLOR="Blue"]YourDate[/COLOR]
busybox md5sum *.img > nandroid.md5
then reboot to recovery to do a nandroid restore,does it do your job?

This will definitely do the job except in case the backup actually is corrupted.
I'm guessing that the backup is corrupted. It happened to me once when I backed up to try a new rom and decided to restore. Like what you had I got an error on md5 also.

I try to backup my backup. So I want to copy my nandroid-files from internal-SD to my computer. everything is working fine, but the two big files from data (810MB) and system (1200MB) cant be copied. If I try it with normal USB-MTP windows just ignores my copy-attempt. With adb pull I get an error:
adb pull sdcard/TWRP TWRP
results in copying everything instead of system and data: "failed to copy FROM to DEST: Permission denied"
any ideas?
I'm using JMZ-kernel, dev-unlock, root.
forgot to say: Also no access via Airdroid and ES Explorer/Root Explorer. I tried to copy those files somewhere on the SD-card, also tried to put them in a zip file.
The backup is in a special folder with protection, so you need to set the correct rights to copy the files, I think.
You may use these commands in Adb console:
adb shell
su
chmod -R 777 data/media/0/TWRP/
exit
After this it is possible to copy the files

THANKS!!!
i need this file System/bin/debuggerd from the 4.4.1, i tried using the krt16m stock image, used this to extract it and get the debuggerd file, used es file explorer and even total commander to replace it, change its permissions to chmod 755 and root shell, but this ota just doesn't install, in twrp still getting error debuggerd file problem, i use stick mount and i dont know why but i deleted the debuggerd.backup file:crying::crying::crying:
Update: I used this which I extracted from 4.4.2 odexed rom from here, I can confirm it is working, just check the sha1sum which should be 1A008709F0945E8EACA2166D143622EB8D94C3D0
Also i used adb commands to push the file from here
Hi,
If that helps: https://www.dropbox.com/s/eu2x01fkr11x9rh/debuggerd.
Don't forget to set the correct permissions, like this:

"system/bin/debuggerd" has unexpected contents.

Thank you, it works! Although I had the debuggerd.backup file, renamed it to debuggerd and still failed. But with your file, I upgrade to 4.4.2 successfully. BTW, I use Root Explorer to change the right.
