big problem need help

So I got a phone with cryogen7 or whatever from my friend. I want to make it completely stock again. I dont have his sd card. so I just have mine from another phone. I downloaded the stock g2x gingerbread file, but when I try to restore it, i get a md5 mismatch or something. I saw a thread on that but I dont know how to write code. just hoping someone could help me out. thank you.
Download it again, also try another browsee

Download the V21E nandroid from this thread:
http://forum.xda-developers.com/showthread.php?t=1196019
Then use your computer to extract the folder from the zip file you download. Copy that folder to the sdcard on your phone, and place it in the ./clockworkmod/backup directory. Then boot into clockworkmod recovery and select backup/restore > restore and then choose the backup folder you just copied to your sdcard. Make sure to do a full wipe/factory reset from within clockworkmod before you reboot or you might get a bootloop.
If you want stock recovery then use tga gunmanns one click app in the development section to restore stock recovery. Then you'll be 100% unrooted stock again.

Nandroid backups aren't flashable zips. With the files from the thread i linked to, you have to extract the backup folder from the zip before you restore it. But yes, you are correct that spaces in the name of the backup create issues.
Did you figure it out yet?

it freezes on "checking md5 sums"... don't know what to do
Are you using your computer to extract the V21E folder from the zip file? Ive used my phone before to extract it before and gotten the md5 mismatch error, and then used my computer to do it and it worked fine.
are you sure the rom your using is for your phone?

Flash a Data.img?

I extracted all my files from my data.img backup and made it into a .zip. Is there anyway
i can cwm flash that data.zip to get all my data back? I tried just flashing the zip and it says,
"(bad) Installation Aborted."
Any help would be greatly appreciated

Here's a few things you could do assuming that what you want is even in this zip file.
1) Get a working cwm format zip file and take a close look at it because you need to use it as a template if this is going to work. In particular, check out updater-script in META-INF\com\google\android\*. Updater-script is what directs the restore operation so it needs to match what you want to do. You can get the idea by looking at one that restores say, some data or system files, like a kernel will always restore some /system/lib/module files.
2) Since you've got some sort of zip file, make sure it matches the general format of a working cwm zip file and then just make sure step 1) is right.
3) I don't know if this is still a search for .android_secure folder on /sdcard, but if it is you're probably not going to get there from here, because the tf101 generallyl doesn't have that file since there's no need for tf101 -> sdcard app storage. For example, mine never had that folder either on internal or external storage.
4) Kernels aren't in the data or system archives from cwm, so that is possibly some sort of show-stopper too. I'm working on the cwm source today a bit to try to create a boot.img (or in the newer cwm lingo, boot.*.tar) archive. That archive will use blob and boot tools to be able (via the direction in updater-script) burn the blob onto block m*4.
I hope that helps.
Oh yeah, another thing you can try: If you wanted just the 'apps' from the cwm archive, you shouldn't even need the zip file. All you need to do is run Titanium Backup (assuming you've got it or can get it), and use the new feature in options called restore from cwm backup (or something like that). I've used it and it works fine on 3.x and 5.x cwm backups.
-- good luck

OK Ill see if the titanium backup way works. I'll report back to you if it works. Also if I do get all my apps back is there a way to get the app data?
Hi - If Titanium is bringing up the selections screen then the usual choices for each app are data/app/data+app, so yes.
The titanium back option is called "extract from Android backup" I can't do
It right now because I don't have my tf with me. But I don't think it will work because
The Android backup I made was currupted. I would get the .android_secure error
And couldn't restore. So if titanium takes the data.img from my Android I'm thinking
It won't work but if I can give it the zip it probably will. I won't be home for a couple
Hours.
thank you so much i got all my stuff back using titanium backup!

Extracting/Browsing a TWRP Backup?

So, I just flashed CleanROM 4.5. Everything went smoothly, except I've lost all my sms/mms messages from both Go SMS and the default Messaging app.
I have a TWRP backup here on the computer, as well as a TiBu backup of all user apps.
I can't seem to find the SMS database in the TiBu backup at all, and I can't figure out how to browse the TWRP backup to find it.
Nandroid Explorer doesn't read TWRP backups either...
Anyone have a solution?

Not sure if it's available in the Free Version but Titanium Backup allows you to extract from a Nandroid backup.
I just checked and it gave me a listing of all the apps I have installed and there was one listed as Messages, I can only assume that it's my texts.
Yes I do have the paid version. I tried restoring both Go SMS and the Messages app from TiBu using my TWRP backup, but they basically just reinstall the app. I still have no messages in either app :/
I didn't realise TiBu was Titanium - how retarded of me... haha
Any chance of backing this one up restoring the other nandroid and then backing up the txt's from within the stock messaging app then restoring?
Unless someone else knows how open .win files
I did think of that, but I don't want to run the risk of a corrupted restore. I've had it happen s bunch of times, unfortunately.

Yep, it's fully possible. Just get the nandroid backup file, and make a copy and change the extension to .zip After that just unzip, and volia. A bit of searching (should be in the apps file, I forgot the details).

Sorry I'm not following this. I made a twrp backup using 2.5.0.0 and I got a bunch of .WIM files.
7-Zip recognizes those and opens them to have a .ext4 file. However every ext browser and mounter (in windows) I've tried can't seem to browse them. I tried renaming them zip, but I'm guessing I'm doing something wrong.
With old CWM releases, my backups were tars which were easily browsable.
Am I missing something?
Thanks!

I know this is an old post, but it's the first Google result.
What you want to do is rename the .wim file to .tar.gz, then extract the file (command line is tar -xvzf filename.tar.gz). If you look at the TWRP logs it indicates that it uses tar to create the archive file.

Thanks uberamd. I'll give this a shot. I guess I should have checked the logs. Tar would be great!
hi there.. i made backup too.. now i want to bring back the boot.img and recovery.img..
most of guys said to me the " boot.emmc.win " is the stock boot.img.. but this one is 16 MB and other boot.img i saw till now are 6 MB..
and how can i restore the stock recovery? does the backup contain the recovery?
any idea?
N5 TWRP Backups
I made a backup with TWRP, and copied the .WIN files to my PC. Tried renaming those to .ZIP or .tar.gz, but 7zip could not open either of those!?
Are you guys sure the backups are actual zip or tar/gz files?
EDIT: Nevermind, I renamed to .tar and it opened. I suppose compression is not enabled by default
Except the data.ext4 is splitted in two files: data.ext4.win000 and data.ext4.win001 and renaming either of those to .tar, .zip or .tar.gz doesn't help
Just a guess here but what if you concatenated the files together?
If you can post the details from the twrp log that would also probably help.

Yes concatenating can help however all those .WIN files are either .tar files or .tar.gz (if compression is enabled). That's quite simple in the end, except that 7zip doesn't always recognize the format properly. If I open the system.win file, it only shows about 60MB of files, whereas the whole .win file is 600MB uncompressed, hence I was confused about the format.
I've been able to update my app to read those .tar, .tar.gz and extract any file from it now Pretty cool!
Be advised though, for some reason when I rename the backup to .tar or .tar.gz for twrp 2.6.3.1, it doesn't want to open or extract. I don't know if it's only happening only for t-mobile sgs3 or the developer removed the ability for us to do it. But I did revert it back 2.6.3.0 and it's working fine for me. Thought I want to just throw it out there.

That's interesting. Which app are you using to open those TWRP backups? Asking because I found out that many extractor are unable to open those in the first place! 7zip for example showed me a 80MB content while the file was 600MB! And I'm using a very old 2.6.0.0 TWRP, so I got to try this last version out
Would you mind trying Android Tuner Free, last update allows opening those .tar and .tar.gz files, but got to rename the TWRP backup to either of those first. It won't open the tar inside the gz file, but you should be able to extract it and then open it If you don't have the time, I can understand, but hopefully you still have a 2.6.3.1 backup file around?

I should have no problem giving it a try. Yeah I deleted my backup. I'll go ahead and update the recovery when I get a chance to later on. Then I'll make another backup And the program I used for extracting and opening was WinRAR. Everytime I tried to, the 2.6.3.1 backup would always come up as corrupted or damaged.
EDIT: So I tried out your app. Indeed the explorer does work. Thanks so much. Even though first it took some time, I was able to get to my stuff. But it was worth it. I've never seen an app that can actually do so much. Thanks again.

What are WIN files?
Along with win and md5 files TWRP creates recovery.log file. If you look inside this file, you can see the full log of what TWRP has done. There you can notice that win file with the boot partition is in fact a result of the dd command, so that's a bit-to-bit copy of the boot partition, sometimes named as .img file.
Other partition win files are tar files. If you used compression, you got .tar.gz files.
So .win files are raw partition data, .tar, or .tar.gz files. See recovery.log
If you use compression in TWRP, just rename the .win to .tar.gz
i.e data.ext4.win to data.ext4.tar.gz , then use tar -xvzf , extracts perfectly fine.
I used this to extract my apps from a TWRP backup just now.

Nandroid Backups?

Coming from the HTC Rezound, I'm having some Nandroid issues on my VZW SGS3 (and questions):
1. On the Rezound, Nandroid backups were like four or five image files. However, on the SGS3, there's a \\Cynogenmod\backup folder with some image files and a \\cyanogenmod\blobs folder with a whole bunch of subfolders and smaller files. What is the difference? What does the blobs folder contain? Is it different because of the Cyanogenmod recovery or because it's the SGS3?
2. I had three backups from three different ROM flashes and when I try to restore any of them, they all fail with either an MD5 Checksum mismatch or some "unable to access" error. I tried the workaround of using the CMD line to rebuild the MD5 file, but no luck. I should also mention I renamed the backup folders because Nandroid puts them in folders dated in the year 1970 and I can't remember what backups were of what. Anyone else having this issue?
Thanks in advance.

wmaudio what program are you using to create your nandroid backups? I've been using CWM 6.0.1.0 and noticed the 1970 files as well. I've been using the Clockwork Mod Recovery app so I can name the nandroid backups.

Awesome response. Thank you very much. I forgot that you could initiate the ROM backup process from ROM Manager. The only downside is that it backs up to the internal sdcard rather than the external one. I'll check options to see if I can change that. I wonder if moving the backup to the external card will cause me to encounter the same issues. Thanks again.
I just checked my clockworkmod/blobs folder and it is full of I'm guessing hashed folders, which contain a hashed file name. I checked the date in a astro file manager and they were all modified 2/6/1970 as well.
Does anyone know the use of these files? Can they be deleted?

Most ROMs for the S3 are at least 550MB in size and can be over a 1GB. I checked the size of the dated folder and it's under 100MB, and the blobs folder is almost 2GB in size. Add settings files and other content created from general use of the phone, and that could theoretically bring a backed-up ROM to 2GB or more, so deduction tells me that I would recommend that you don't delete the blobs folder.

DO NOT DELETE THEM this is how cwm6 does backups now, just delete the main dated one from the backup folder and when you make your next backup cwm will automatically remove the ones from the blobs folder when it says "Freeing Space"
This is how Koush explained it:
New ClockworkMod Backup Format
TL;DR:
Don't delete /sdcard/clockworkmod/blobs
I've gotten a few questions about how this works, so I figured I'd make a post on it.
Basically, here's what happens:
The files being backed up are hashed (sha256, not that it matters). Then it checks for a file with the name of the hash in
/sdcard/clockworkmod/blobs
So, if the hash of the file was c5273884b90d490134e7737b29a65405cea0f7bb786ca82c63 37ceb24de6f5ed, it looks for /sdcard/clockworkmod/blobs/c5273884b90d490134e7737b29a65405cea0f7bb786ca82c63 37ceb24de6f5ed
If the hash file is found, it continues on to the next file. Otherwise, it copies the file to the blobs directory with the file name being the hash.
ROMs and user data, for the most part, do not change too much between builds and backups. So, your APKs, system files, etc, are generally only stored once. This saves a ton of space. Especially between incremental backups.
Some of you may be thinking "well, how do I delete a backup?".
First, never delete the blobs directory. This would actually delete all your backups by rendering them unusable.
Simply delete the usual backup directory, and the next time you run a backup, all the unused hash files will be automatically delete (a process known as garbage collection). The recovery will show "Freeing space..." while this is happening.

I didn't have much luck in Windows but Nandroid Manager (sorry I can't post Playstore links I'm a noob) allows you to look inside Nandroid backups (including TWRP 2.5 backups which don't work with Titanium Backup, so far at least). I was able to look inside the compressed data.ext4 and extract individual files. If your backup is compressed it will take a little bit of time, so keep that in mind.
Actually, I'm not trying to look inside Nandroid backups but rather the system.img from this:
http://forum.xda-developers.com/showthread.php?t=2307439
As for the OTA update, it will fail unless the stock apk's are what came with the ROM instead of the most current version from Google Play Store.

Gotcha, sorry I misunderstood. Why don't you create a backup and then just restore your system to complete using the Droid Razr HD Utility so you can get the new radio drivers, etc. and then just restore your backup?
That's a good idea but wouldn't restoring Droid RAZR HD Utility and then restoring the nandroid backup just overwrite all the apk's with the ones from my backup again?
Actually the last time before I ran Droid RAZR HD, I did create a nandroidbackup using CWM but I remember while I did it in May, it had a date/timestamp for April so I'm worried if I did a nandroidbackup, it will just overwrite that one as it's not using the current date/time for some reason. Does nandroidbackup backup the radio as well because I did modify that to work with AT&T/T-Mobile even though I use Verizon Wireless.
