Make back up of froyo sd card?

Any way to transfer Froyo from one SD card to another?
I would like to move it to a larger card but on my mac only 2 partitions mount but would love to put it on different device
Can this be done with adb?
is there a tool?

For windows you can use Win32DiskImager. You just select the letter of the drive containing the sd card (must be on an sd reader, not nook itself).
For linux you can use the command dd. You just have to do:
dd if=/dev/sd"letter of mount point here" of=/home/User/Desktop/SD_Backup.img
(to check for the letter you can use gparted, it can be gotten from the synaptic package manager if running ubuntu)
As for Mac, i have no clue. That being said you can easily download an Ubuntu live cd and use that to back it up

How do I know the mount points? Can I just make one. Img file that will expand to the 4partitions?
From 1.1 Nook Color with 1.1 ghz overclock

Load up gParted once in ubuntu, in the top right it will have an arrow pointing down that lets you switch physical Hardrives (or in our case an SD card). Unless you have multiple HDD that are 2GB or 4GB (whatever size your SD card is) it should be easy to be able to find which one is the SD card. It will be /dev/sdX where x is the letter its mounted under.
Once you get that letter open up a terminal and type
dd if=/dev/sdX of=/home/"You User Name Here, exclude quotes"/Desktop/Backup.img
again, where X is the mount letter
Once it's done it you will have all 4 partitions backed up into one img file, so once you wish to restore it you just type
dd if=/home/"You User Name Here, exclude quotes"/Desktop/Backup.img of=/dev/sdX
(and again, X being the mount letter)
If you just wanted to say backup your /system partition you would do
dd if=/dev/sdX2 of=/home/"You User Name Here, exclude quotes"/Desktop/Backup.img
no number = backs up entire card
1 = backs up boot
2 = backs up system
3 = backs up data
4 = backs up media (stuff that your nook see's as being on the sd card such as what you download from a browser)

Is there a way to make a working backup (that can be recopied to a different card) without switching out of Windows Vista 32 bit? The backups I made with Win32DiskImager or WinImage don't let the NookColor get any farther than the flashing 'android_' screen at start when I copy them to a different card.

Try packing your boot, system, data and sdcard partitions into a .img file then use winimage/win32 or dd to write the image to a new sd card. (Kinda like making your own custom ROM image.)

@ RileyGrant - Thanks for the quick reply. I haven't done much coding in years and the Nook is my first attempt at rooting/roms/etc (better to brick a $250 toy than a $500 one...). Anyway, I don't have any problems following instructions - can you point me to somewhere that would explain the above procedure in more detail?
Thanks!

I have the same problem. I 'm trying to move froyo to a 16GB sdcard but it keeps getting stuck on the "Android_" text. Any advice?

You probably failed to reproduce system permissions while copying files.
An easy way of transfering a working OS from one SD to another would be to:
- Download my USB mass storage utility in dev forum
-Install it
- Mount each partition of your SD to your PC, one at a time.. And do the following for each of them:
- Make tar/zip files of partition content
- Then uncompress the files on each new partition of the new SD..
Don't forget to expand 4th partition for maximum SD capacity...

Worked like a charm! Thanks Sam!

Is it possible to run stock image of sd?

Sorry if there is a thread like this somewhere but I couldnt locate. I was wondering if there is a stock 1.1 image we can run off sd. The only real reason I want to keep the stock image is I have some kids book that dont work through the app. So I would like to be able to boot froyo from internal for the speed when I am using and boot stock off sd when my kid wants to play with it. Thanks in advance

Possible? Yes. Has anybody bothered to do it yet? Nope. The demand just isn't there for the amount of work required.
There's a froyo + stock dual boot available though. You get to choose at boot up whether to load stock or froyo. Look in the dev section of the forums for the thread on how to do it.

From what I've read you should just be able to decompile the uRamdisk, and recompile it after editting the init.rc file, mapping mmcblk0p5 and mmblk0p6 to mmcblk1p2 and mmcblk1p3. Then just dd mmcblk0p5 to mmcblk1p2 (you may need to shrink it depending on the size of your sd card) and copy the new uRamdisk and uImage to the boot partition of the sd card. I assume the u-boot.bin from any of the other sd card builds would work, alongside the same partition layout

Thanks for the replies yeah I get the lack of demand issue. I just wish the nook app had support for those books. Guess I will just setup the dual boot on emmc and if I read up some more and get brave try to get it done myself.

Very easy to do..
-Enter adb shell and enter 'busybox fdisk /dev/block/mmcblk0 -l' to print partition layout.
-Reproduce layout on the sdcard, with gparted/easeus. Don't forget the boot flag on first partition. You can extend media partition to use the remaining sdcard space.
- use my USB mass storage utility and mount each internal partition
- make tars/zips of every partition content.
- extract tars to SD partitions.
- then, as said above, edit init.rc (if you're too lazy, i can post one here, takes 2 mins to do)
- insert and boot..

[Q] Format SD card to ext2

I bought new SD card i want to wipe my phone completely and install Darkys Rom. I formated my new SD card to ext2 in Ubuntu but my phone didn't recognize the file system. Then i used Clockwork to format my (external) SD card and what i did i formated my internal SD card. I'm completely failed. Can somebody give me step by step tutorial how to format external SD Card to ext2 or ext4. Also i would like to know if i will be able to copy data under windows when the phone is connected through USB.
Thank you
Sorry for my English

Hi! Please tell me why do you want to format your SD card to ext2 or ext4? There is no need for that. Just format it tu FAT and that's it. If you want to apply lagfix then do it under recovery with the lagfix option under advanced features.

I would like to have option to transfer bigger files than 4GB.

how do I format my external SD card to ext2? I have Samsung Captivate. I got Cygwin, since I use Windows. Does anyone know what commands to type in cygwin?
I want to put files larger than 4GB on my card as well.
I think this will be useful for a lot of people.

I found a thread http://android.modaco.com/content/h...an-i-bind-mount-e-g-system-sd-xxx-sdcard-xxx/
But I am a noob in Linux, and it would be GREAT to have step by step commands I would have to type in to format my external SD card, while its in the phone, etc
Possible problem I see is that the phone might not recognize external card if its ext2/3/4 . We might have to have small FAT32 partition on there as well? Or may be Froyo has that ability...

I'm looking into doing this myself, in my case so I can use symlinks to copy apps "data" folders (not the "data" partition, but the folders in /mnt/sdcard where apps put different things) onto the larger, external sdcard. It seems like it could be possible, just need to make sure the /etc/fstab file is updated properly, and of course make sure your kernel has the ext2 and/or ext4 modules loaded and running (which you probably will if you have a lagfix installed). I will play with this and post back my results here...

I have been looking for this myself for a while aswell, but on 4 different kernels and CWM v2.5 and CWM v3.0, I couldn't find any option on how to change the ext. SD to Ext4. If anyone knows how to then please post it here!

So, progress report...
Still no success in this matter, although I have learnt a bit today about Android's internal workings. After backing up my system with CWR, I first tried formatting my ext sd card with gparted on my computer. Bad choice... Even though no config files were stored in it as far as I could tell, Android "panicked" and decided to restore all my configs to default, severely crippling my system and making a lot of apps force close when I restarted the phone.
At that point I thought, since it is now broken, might as well play with it So the next thing I tried was formatting my internal sd card (only the vfat partition that gets mounted in /mnt/sdcard) to ext2, but this time using the "busybox mke2fs" command, on the terminal emulator on the phone. This seemed to be successful, and I could read and write to the new ext2 partition, although for some reason, I got the feeling that apps kept resetting their settings (not sure what caused this, didn't really looked into it much). So once that was up and running, I decided to modify the /etc/fstab file, like I would do in a normal linux environment, to automount this partition on boot, as ext2.
At this point I rebooted the phone, but hmm... Android converted the partition back to vfat. Not good. This leads me to believe there must be some kind of "recovery" commands run on startup, in case the system detects the partition is not the default file system, or something along the lines of that. At this point it got kinda late, so I decided to document my progress, restore (which thankfully left my phone the way it was at the beginning of the day) and call it a day.
So, things that I still need to find out:
1) How does the system convert the partition back to vfat on startup and how could I avoid it from doing it? Maybe by having a small vfat partition to fool it into thinking all is good and normal?
2) When I had my partition as ext2, I couldn't see it on my computer when connected via USB (I'm on a linux system so the fs being ext2 is not a problem). Wonder why...
3) If I had a small vfat partition, how would I go about mounting the ext2 partition on the same mount point after the system checks the vfat one? Maybe by binding it? Gotta look into that as well.
4) Finally, have to check why the apps couldn't maintain their settings after a certain amount of time (for example, if I opened terminal emulator and changed the colors, these would stay if I closed and opened the app again right away, but if I closed it for a while, say half an hour, and opened again, it would be back to default...)
I'm on a Galaxy S btw. If anyone has any insight on any of these matters, would be much appreciated!

Any progress? Would really like to use +4 GB files.

It is immpossible because of hardware limitations of the SD card And often if the file is big it just fail!

Not true, read the rest of the thread before u post! Its not a hardware limitation, its because Android uses fat32 as filesystem.

hello everyone,
I just wanted to check to make sure that there is no solution for this 4gb limitation with Android yet? I too have been looking for something besides resizing files.
thanks

I have ext2 on my external 32GB SDCard, just formatted it on my PC and put it in the phone, working without any problems. I just watched a full length 720p movie with DTS sound on my phone without having to re-encode the mkv
I'm using CM7.1 on my phone which auto-mounts the SDCard even with ext2. It won't work on stock ROM, but any kernel that has ext2 support should be able to read ext2-formatted cards but they might not auto-mount the sdcard.
On my PC I had to install a ext2 file system driver (google ext2fsd) for Win7 to be able to read the card when attaching the phone to the PC.

How do I convert my SD card to SD-EXT & swap file WITHOUT losing apps?

Hi,
I have the N1 with SD card in FAT32, and most apps were moved to SD using App2SD, and I am rooted.
I hear that EXT3 or 4 gives me advantages.
How can I convert my current SD card to a partitioned, swapped, EXT3 or 4 card, and keep all my apps working?
Can I just copy the SD contents to my Mac, then use Amon, then restore the SD and it'll all magically work, or will I lose all my apps by copying the SD contents to Mac?
Also please advise the ideal swap size and other sizes when partitioning in Amon.

Can I suggest you titanium backup for prevent losing app's preferences?
Make a full backup of all apps with tb then copy all your sd on computer and you're ready to partition or wipe and flashing all u want!
For me 0mb of swap and 1024mb of ext3/4 works great!! I'm with cg7 so I'm able to use s2e, it's really a greate app, search it on market !

You can definitely copy all of the files on are SD to another computer. I would always backup those up from time to time.
My personal preference is to boot my laptop using a USB drive with Ubuntu on it. Then I can use gpartd to repartition without recopying the data (BACKUP ANYWAY!).
gpartd allows resizing and creating partitions while maintaining the data.
I created a 512MB partition (no swap) and used S2E to move all my apps from the FAT32 partition. Worked great.

Thanks, I tried as you both suggested and succeeded with relatively few problems.
How do I actually click 'Go' in S2E. I have checked the box 'Applications', but I can't see how to actually make it 'Start' moving them. Or does it just happen automagically on reboot?

One added thought--
I prefer sdformatter to format card. I find after redoing sdcard from time to time with this flashing mania, that the phone does not format as cleanly and remnants are left behind--can cause issues

Check the box, then reboot.
And you're good to go.
Remember to move back apps from SD to internal (internal is now your SD-ext)
And don't forget to set install location to internal in CMsettings

If you got a computer with a Linux distribution, you may use gparted and resize your partition without any need to format it entirely ;-)

[Q] HD+ Hybrid Install to EMMC

So I have the hybrid install working per instructions here: http://forum.xda-developers.com/showthread.php?t=2300132
I've decided to install full and overwrite stock emmc. My computer is out of commission for the foreseeable future so I was wondering if its possible to migrate to native install by simply downloading the files for 10.1 emmc and emmc recovery to the internal memory/SD card, booth from hybrid/SD recovery and flash those files?
Don't care about saving current apps/data, I'm fine with clean install.
All help is appreciated. Not a newb but need some help.
Thanks

You could do it that way, but it is best to use this procedure:
Copy the two files to internal memory.
Boot to the SD and install the emmc recovery from internal memory.
Remove the SD and boot holding the power key and n key as soon as the nook logo appears, releasing after a few seconds, putting you in the new emmc recovery.
Do a nandroid backup to internal memory.
Do a factory reset/wipe data.
Flash the new CM10.1 ROM zip from internal memory.
Reboot and everything should be good.

Thanks leapinar this worked great. Downloaded twrp redovery , 10.1 emmc to internal storage, booted from hybrid SD recover, flashed twrp recovery, removed SD, rebooted, flashed 10.1.
Working great except new emmc install doesn't allow landscape lock screen whereas hybrid 10.1 did. Guessing this will be fixed in future update. Thanks for the help and all the great work.

Thought I'd drag this thread up instead of starting a new one as I went down a similar path. I was running bokbokans hybrid and followed the instructions in this thread to move to a EMMC install (Carbon ROM) which went fine.
I just have a few questions on the transition to EMMC:
1) How can I get rid of the Cyanoboot menu that pops up briefly at start up as I won't need this any more.
2) If I look at my SD card in CM file manager (or on a card reader in Windows), it's just showing me the boot partition (115MB). Is there any way of accessing the data/files on there or should I just reformat the card to get the storage back (it would be useful to copy over some of the stuff I had on there but it's not essential).
3) If I look at the Internal Storage, it has a sub-folder called "0" which replicates some of the folders etc from the main internal storage area. Is this a carry over from the hybrid installation, ie. can I delete this sub-folder?
Thanks

1. You don't want to get rid of the cyanoboot logo. It is used to get Carbon going.
2. You eventually want to format the SD with SDFormatter to get the space back. But if you can still boot to the hybrid, then copy your media files from it first using MTP to your PC. If not then just format over.
3. That 0 folder is part of your new setup. Leave it alone,
