Couple of things...
Your backup might be corrupt if the md5 doesn't match.
or you might want to try and make sure you have the latest version of CWM installed on your phone. I read in one of the other threads that someone had an md5 mismatch problem that was solved with a newer version of CWM. I hope this helps.

I had this happen to me once. Turned out the nand backup was bad....used the previous one I had made and was back in action. Had a few moments to sweat it out though. Just make sure to backup regularly and archives them.

With that said...
Is the only issue that you can't make a backup or have you encountered other problems? Did you flash the superuser zip before making a backup? Did you try making a nadroid backup more than just once and it errored multiple times? Will the phone boot for you?
You could try to boot the phone up and reboot into recovery and try making a backup again. If all else fails you can just reflash everything back to stock and re-root. Make sure to read through all the guides very carefully and then...read them again....and when you get done with that....read them again. =)

This is exactly how I do it. I've never needed it but have always had it for emergency. Now that ICS is out I've been going back and forth from the sandwich to gingerbread because the bugs are well.......bugging me. I odin'd the leak then I backed it up after I installed cwm so I could always go back to that after testing out these other roms, cwm flashes, and even the backups of ICS, then I root. I basically have started from scratch twice and both times I went back to my backup I got the mismatch ( 2 different backups of the leak). I know its me (possibly cwm) because the cwm ics backup that's out there restores fine.

Are you extracting on your PC? There seems to be some problems with unzips on the phone causing a mismatch
I've been using 7-zip for mine, and it works great. Extract files on the desktop, place on the external SD using USB

Got this from another forum
You can actually manually do it, and maybe get that backup fixed. Go to the backup folder /sdcard/clockworkmod/backup/*rom name (date and time usually)/
See if there is a nandroid.md5 file in there. If so, delete it, you can back it up if you want but it is busted so no point.
Next step to open adb shell or terminal emulator and type:
Code:
su
cd /sdcard/clockworkmod/backup/*rom name (date and time usually)/
md5sum *img > nandroid.md5
reboot recovery

Not totally sure that I'm correct but I had made two backups on one version of cwm and then upgraded my cwm to the touch version and the two backups from the previous version wouldn't restore because of md5 mismatch. Those same two backups had worked several times perfectly on the other version of cwm as well. So I just assumed that maybe the version change had something to do with it.

adb Problem
Hey Guys,
nice tutorial. Everything worked but the adb shell itself.. I had to type all in one command. My adb shell freezed after entering the second command. Anybody knows how to fix it?
I used SiyahKernel S2-v3.4.1 and the ADB Shell in the Recovery.

Try using terminal emulator from your device

ADB Shell
Yeah, it is the international i9100, but the way to fix a broken CWM-backup is the same. I've tested an cm10 alpha and after this I wanted to restore my ICS, because of sdcard problems. So I did a fullwipe and only have had the Recovery left. How can I get a Terminal in there?
I thought about another way to fix the MD5: Maybe its possible to do a MD5Sum within windows over the boot.iso and save it to a .md5-file. You have to format the md5-file the way CMW needs it: "MD5sum /sdcard/.../boot.iso". Would this work properly?

Not sure if it will work or not. Try to follow the steps given in the following thread and also just incase you may need it make a copy of the backup folder. 20 seconds tutorial to fix MD5 mismatch error no terminal needed

I fixed my md5 with the adb shell.. but I had to do this in one command . After reading this tut, I think there only has to be the MD5 of *.img, not of the .tar. Am I right?
Maybe its possible to script a zip-file for CWM which recalculates the MD5 of existing Backups?
The bash commands are simple. You only have to do this in a loop for all folders in /sdcard/clockworkmod/backup.

[Q] Questions on Bryan's CM7 build

I didn't want to clutter up the dev thread with these questions, but I've never used any CM build on any phone.
I unzipped Bryan's CM7 build to see what was inside and noticed it didn't seem to have a launcher and didn't seem to have any market app. Ok so does that mean you have to pre install Google apps from the SDcard to be able to access the market?
In reading the instructions, it seems like Bryan's CM7 build uses the same kernel as his regular beta kernel thread but that can't be right, can it, with the discussion on the thread....
I noticed that the Google apps were all modified for CM7, so does that mean that ordinary apps won't work unless they're modified?
Can I still use the TW4 launcher on CM7? Used to it.
The business about USB storage not working in Android. I assume that means you can't put anything on the SDcard using the USB cable after Android has booted up so that you have to push everything on there with ADB, is that it, in recovery mode?

1. It does contain a launcher; Its called ADW Launcher.
2. Yes, you would need to flash the google apps. I use this one
http://goo.im/gapps/gapps-gb-20110828-signed.zip
and this one http://goo.im/gapps/gapps-gb-20110828-newtalk-signed.zip​
3. You flash the gapps-gb-20110828-signed.zip file then the gapps-gb-20110828-newtalk-signed.zip google talk with video chat support.
4. Its a different kernel. CM7 is using the MTD version. While regular stock roms use BML.
5. I believe you can use the google apps on those files on any rom. But most roms already bring them integrated.
6. Apps developed for use on the Galaxy S phones like TWLauncher et al will not work as they hook onto some samsung specific programming.
7. As mentioned in 6, you cannot use TWLauncher on cm7.
8. Yes you would have to push everything through ADB in the meantime. Pushing/puling through adb does not require rebooting to recovery though.

Can someone make a video on how to install the rom?

Just follow the written instructions on the thread and you'll be fine

Honestly they confuse the crap outta me. A video would dumb it down for me and im sure a few others.

IDK how the heck I made my efs backup.
But if anyhow, you manage to make some sort of a tar file with your efs files, you should be fine.
After that,
do the erase_image
and mount /efs
and cd /efs
and tar xf anybackupname.tar
you will install. That is if you get your.

My suggestion is to wait until the install procedure is easier.
In the CM7 OP, Bryan said (twice) to re-read OP after updates.
Making a video will give you proper instructions for this build, but if Bryan updates the install procedure users following the video are going to have a mixed bag of results, and possible bricks.

I have a question as well. Yes, I know that this isnt exactly high priority, but I'm wondering if later there will be a build with Wifi calling. I was trying to install it myself, but it kept force closing, and I don't wanna try anything that'll mess up my phone any worse than I have before.
Wifi calling is basically a must for me since I basically live in Smallville, KS. I get little to no service here, and without it, it usually takes forever to get anything. And yes, I've tried every modem I could, KG4 works best, since I can sometimes get one bar.
I'm trying to complain or anything, and I thank Team Acid for bringing us CM7.

Neo I'm sure at one point bryan will get that working.

So does that mean that NONE of the apps will work unless modified to run on CM7? Or are you just talking about certain Samsung issued apps? I'm in the middle of an old Tarzan novel on my e-reader program on the phone...

I have a question with the process flash boot.img with heimdall...when i open heimdall front end and put boot.img into the flash local package..i get a error the tar header contained an invalid file size..on the flash tab, it only takes pit files..also when i just use the heimdall ..a black screen happens similar like a command prompt and just exits..
how do i flash the boot.img with heimdall?
This is using fbs instructions that I am using and i am stuck on step 7. flash the latest boot.img from bryans op..

Are you on windows? If so open command promt. Cd into the heimdall suite directory. Put your phone in DL mode and connect to usb. From command type "heimdall detect". Should say device detected. Then just put the boot.img in the same directory and follow the OP.

That's just Samsung-specific stuff like TouchWiz that require Samsung's modified frameworks and extra libraries.

Just use FB's install guide instead. I was going to wait until it was installable through CWM, but this is essentially the same thing with a few extra steps.

Backup raw sector-by-sector image of a partition

I have a non-rooted Galaxy Tab 2 7.0 P3113 that was factory reset, so I'm trying to dump the data partition sector-by-sector to microSD to try to recover data.
Since there is no way to mount the internal memory as a hard drive through USB, it makes the most sense to use an aftermarket recovery which can read the sectors and write them to an image file on the microSD.
But I don't know if CWM or TWRP can do this. Obviously they can back up to microSD, but I've never heard of someone having issues with the 4gb file size limit of FAT32. That means the backups are always smaller than the full size of the internal memory!! Somehow they have a way of distinguishing used space from empty space, but the empty space is exactly what I need to copy in order to recover files.
Which brings me to the next issue-- the size of the partition images. TWRP apparently supports exFAT so that shouldn't be a problem. CWM seems to require some hacks. So does anybody know how to force TWRP to backup ALL sectors of a partition to microSD?
Edit: The DD command would also work but I don't know if it's enabled when you ADB in to a Galaxy in TWRP. I can't just try it because I lost the USB cable.

You can use Android Terminal Emulator on the phone and use the dd command providing you have Busybox installed.

The problem is that requires rooting and downloading/installing a big app, which will overwrite a bunch of data... Right? Unless you can keep the files confined to the system partition I guess.

Just found out that TWRP can split up the backup so it can even use a FAT32 microSD. Pretty cool.
I just wish I could find out if it backs up the "empty" sectors. I emailed Team Win and they didn't reply.

I imagine that you could write a CWM zip that would copy the terminal emulator apk to the /system partition, but if I were you I would just shell out for a stock USB cord to use with ADB shell. You can find them online cheaply, and if you plan on doing any sort of rooting/customizing, you'll need one.

Oh I ordered a cord. I just meant I couldn't try it right away.
I tried some ADB shell stuff before I lost the cord and I couldn't even get it to list partitions. They really lock it down I guess. As I understand, you do have ADB access from TWRP, but I don't know if all the commands work or if you have root access.
Edit: It turns out TWRP backs up the boot and system partition as IMG files using the DD command, but all the others are backed up as simple zip files. I guess they decided no one would want to get a raw image of the data partition. Seems strange because extracting files from raw sectors is a common method of recovering files from camera memory cards etc, so why not a tablet/phone?

That would give root access while you're connected to the Recovery with ADB shell? Just type "root"?

So long as the device is actually rooted... Oh. Darn. I just remembered that the stock ROM has a bug that stops this from working. There's a kernel (flashed with ODIN) that fixes this for p5xxx, but it's not for 3xxx tabs. Maybe that's because they don't have the bug, though. Try it and see, but it may or may not work.

Well it's not rooted to begin with.
I'd be happy to root IF I can root without writing anything to the data partition. So far that seems to be impossible.

What Android version are you using? I might be able to modify the standard root zip to use the /system partition exclusively.

Wow, that's possible? I think that would be useful for a lot of people trying to recover data.
Oh and what about the cache partition? Does the camera app store pictures temporarily there? If so that would be another source to try to recover pics from. Or do apps ever store docs there? Or is it not worth trying to preserve?
I was planning to use CF Auto Root but I asked Chainfire about it and he said that it can format the data partition if it becomes unreadable, so I didn't want to risk it.

Build number IML74K.P3113UEALD3
Model number GT-P3113

Well I guess this is all moot because I can't even figure out how to flash TWRP for the P3113. I downloaded an the .img file, Odin recognizes my device, and I got it into Download Mode, but I don't know how to set up the img as a tar.md5. You would think whoever made that .img would have provided instructions on flashing it, or just uploaded it as a tar.md5 since that's what you need. That's something that really annoys me about the Android community-- folks assume everybody knows what they're doing.
But the worst is all the threads where people ask how to flash TWRP to a Galaxy Tab 2 7.0 with Odin, and the replies are all "Just use CWM".
I found a download for the TWRP 2.2 for some Galaxy phone but I can't even examine the format of the tar.md5 because the freaking download site requires registration. Even if I duplicated the format, no idea if it would work. http://forum.xda-developers.com/showthread.php?p=30694404

I think all you need to do is rename the file to "recovery. img" and use 7-zip to put it inside a tar archive, then flash the tar with ODIN.

Apparently it's not that simple. Somehow you have to integrate an MD5 checksum with Linux console commands http://androidadn.com/2012/09/how-to-convert-img-files-to-tar-md5-to-do-a-flash-with-odin3/

Also, I was reading about Heimdall. Anybody know if it will work with just the .img file? http://www.thepowerbase.com/2012/04/slay-odin-with-the-mighty-heimdall/

Yeah, if you can get Heimdall running, you should be able to flash TWRP with that.

Well I've tried every driver I can find but I can't install the tablet in TWRP Recovery mode. Windows sees it as "GT-P3113"

Wait... Can't I load a rooted system image onto the tablet from Odin? Wouldn't that leave the other partitions unaffected?

Currently attempting a cw-9/10 port to this device, however; we're still needing a stock rom for it, if you happen to have the phone I would be more than willing to help walk you trough data dumps of the systems primary partitions recovery/modem/system/boot.
This is important to have a 'default return to' unfortunately I'm unable to use my phone as a stock image as I heavily modified the system partition shortly after rooting the device thinking there would be roms forthcoming soon..
Note to self: in the future always always always get a stock restore FIRST!

note these commands may take a while to process
when your done, you can zip and upload the files to an upload service, or Google drive and share them.
I'll create an odin recovery

Hello no need for you to pull flash files from your device, I've finally been able to restore my phone to stock 4.1.2 through a somewhat convoluted process so I'll now be able to create a stock restore

Thank you sorry I had some family issues or I would have been quick on it plus couldn't log in for a day hmm anyway last night there was an ota update seemed the size of whole os is there somewhere in root files or elsewhere we can extract this? And if so would it help us in anyway I would like to start working on learning more and helping teams build custom ROMs and seems like this might help.

No worries, first off check your build number if it end in I1 or F1 we have that update already saved and uploaded to shared services, if you are VVBNA5 you have a new update we have not seen yet.
In any case, install OTA rootkeeper available on market or you will loose root, and have to odin flash (custom) to re-root.
Also, updates can be found at /cache/FOTA/update.zip
local caches up updates can help developers fiddle with multiple versions of the OS without relying on updates via OTA updates. or backups etc.
So far, all the patches that have come out for this device are 'patch based' only IE not much help other than to allow people to download the update manually, or for devs to check out potential 'mods' against multiple versions.

i have this phone i rooted it via cwm even tho its a temp. recovery

System dump needed for a ROM project

Hey guys well I wanted to ask who's available and has some knowledge with adb to run some commands for me and send me the system.img dump and boot.img dump so I can work on a project and start of at least a stock rooted tweaked ROM thanks the sooner I can get those stuff I can work on something so let me know guys and also once you have them upload them to drop or filehost or whatever you can and send me the links to those files
These are the commands to run
And make sure you guys have USB debugging enabled
For system dump run
adb shell
su
dd if=/dev/block/sda18 of=/sdcard/system.img
For boot dump run
adb shell
Su
dd if=/dev/block/sda8 of=/sdcard/boot.img
I have knowledge in making ROMs and other stuff so once I get all this I can start dishing out something good and only reason I'm asking for the system and boot dump is cuz I'm still waiting for my phone but I can still make a ROM while I wait for my phone to come
Thanks in advance

Uploading now will edit and paste link once done

I also have a fairly generic firmware if you want to build one from that.

want the system.img and boot.img since I already have my PC setup to get work done with those files
Have you uploaded the system.img you dumped?
Sent from my Nexus 6 using XDA Free mobile app

Mega is being slow for some reason its at 85% complete now.

As long as it finishes lol its good and how big is the system.img you dumped
once I get both of the files I can hopefully get something out this week soon
Sent from my Nexus 6 using XDA Free mobile app

System.img = 3,921,674,240 bytes (3.92 GB on disk)
Boot.img = 29,360,128 bytes (29.4 MB on disk)
Compressed = 1,635,969,218 bytes (1.64 GB on disk)
At 95% right now

Here are the images
https://mega.co.nz/#!tMkThLZQ!H_8BRKaH_r8glwpMQCN7NTEPeSLXRoZDvCNiiU1f3ac

Sounds good well then I will get my ass out of the bed and onto my computer lol have a lot of work to do
wow your system img is way bigger than my Buddy's dump which he said was around 2 gigs lol do you have a lot of apps installed ?
Should have asked for a freshly factory reset then backup lol
But I can work with the system img u send me right noe but if its not to much to ask can you make a backup with twrp just so u can save your stuff and then factory reset and dump the system img again and see how big that one is
It should be was smaller so I can use that dump to finish my work
Sent from my Nexus 6 using XDA Free mobile app

Yeah I can and that's strange cause I only have to applications installed. Just in case though I will wipe it and do another dump for you

Okay thanks appreciate it and yeah my Buddy's dump is smaller idk why but yeah if you can factory reset clear cache and dalvik then fresh install no need to log in just go straight o USB debugging enable and dump again see if there's any size difference
I'm working on what I have right now so will have something soon and with your clean dump I can check the difference and get rid of anything that got added before a clean dump
Sent from my Nexus 6 using XDA Free mobile app

Ok, I've done a full factory wipe and with out booting to system i'm running the dd command in twrp so it should be 100% fresh system.img
Also to note after i do boot in system i loose about 10GB of storage space 64GB down to 53GB this is without signing into google play / samsung or anything just a fresh install and a bypass all boot up steps.

Hmm according to this
957440+0 records in
957440+0 records out
3921674240 bytes (3.7GB) copied, 33.662824 seconds, 111.1MB/s
its still 3.7GB even with a full dump
I can also flash the stock firmware using odin to verify this. Is your buddies a Sprint Edge as well ?

Yeah you never get the whole 64 gigs worth of space especially with Samsung its usually low but yeah let me know when you get the system.img I tried using my friends img he didn't but didn't work and I'm downloading the one you sent me see if I can extract that one hopefully no issues while dumping it
Its harder since I don't have the phone yet as I'm waiting for it if not I would get the stuff myself lol
Sent from my Nexus 6 using XDA Free mobile app

Can you try this
adb shell
su
dd if=/dev/block/sda18 of=/sdcard/system
And see I'd it dumps it for you in a system folder and if it does then just put it in a rar folder then upload and I won't need to extract the image
Sent from my Nexus 6 using XDA Free mobile app

That does not dump it in a folder, it just dumps it as a file called 'system' instead of 'system.img'
I was able to mount this is macosx ext4 so it should be a good full dump.
Just in case though I am uploading the clean never booted system.img now.

Angel, I'm not sure if it matters but I did a lot of manual debloating which is probably why my file is so much smaller. Were you able to use the file I uploaded to Dropbox?

Yeah I got it extracted after a bunch of tries lol and also I downloaded the stock firmware and extracted that and got the system and boot and everything I need to work on the stock ROM
Working on it now will try to have something tomorrow for both of you to flash and let me know how it is
Right now I'm just gonna make the insecure boot img and edit it to change boot animation without having to change the Samsung files and other than that should be stock rooted until I work on more with it
So keep an eye out on your PMS tomorrow hopefully so you guys can test for me
Sent from my Nexus 6 using XDA Free mobile app

What program did you use to extract the system.img?
Edit...
Building the ROM now so far everything is going good bad news I have to go to work in about an hour lol
But I will continue this when I get back home and should have something for you guys to flash tomorrow

If you need another tester, let me know.
Got plenty of experience doing this, have TEP too, just in case... lol
