This is a general CWM question but I could not find any place better to post on XDA, so excuse this if incorrect location.
I have flashed all the Skyrocket ICS roms in the past few days to see which I liked best. Before I flashed a new one, I would make a CWM backup of the current one. Wanting to easily be able to identify the files, I appended the rom name to the end of the CWM filenames after deleting all the characters after the date, which appeared to be a GMT time stamp. Now, when I try to restore any of those files, I get an MD5 checksum error. I am only assuming that this is due to changing the filename and not some other problem. Anyone have any ideas on how to fix this? TIA.

Are you talking about the folder name? Because that shouldnt affect it. Inside the folder that is created for each backup, there are backup files which dont have any dates/times in the filename itself.
I vaguely remember reading about this, but I can't recall how it was resolved. Try updating your can to 5.5.0.4 Touch or 5.8.1.3 (?? something along those lines) and seeing if that resolves it. Outside if that I must ask the obvious, did u Google "md5 checksum error cwm"?
Are you using the same CWM version as you did when you backed up? If you didnt, then thats one reason. You have to stay on the same CWM version, many of these CWM versions floating around have different fixes in there.
One way around this is to go to Advanced Restore and restore all the IMG files from there.

I figured I would post this fix here in case anyone else ran into this problem. This is assuming you did not change the folder names and let Clockworkmod create them. I haven't had it happen until today, but it's not a nice message to see when you are trying to do a restore.
Code:
Checking MD5 sums...
MD5 mismatch!
Do this to fix:
To fix this problem use the code below. Substitute the final folder name for the backup you need to fix.
Code:
adb shell
# cd /sdcard/clockworkmod/backup/2010-06-29.20.22.53
# rm nandroid.md5
# md5sum *img > nandroid.md5
When that finishes, re-run the restore and everything should be fine.
NOTE: As rpearl stated, there could be something really wrong with your nandroid, so use this tutorial as a learning experience and not a fix-all. In my case, everything was fine after restoring. However, that may not always be the case. Do this with caution.

That is correct on most of them. I updated to CWM Touch for the last one, but it did not restore either. To check this out, I just did a backup and without changing the name did a restore and it worked fine. The thing that was odd in the backups that would not restore was that it immediately bombed out of the checksum each time as if it was checking the name itself first.
That is brilliant. I did not realize you could generate the MD5 from ADB and stick it right into the folder. Thanks!
The few times this md5 mis-match has happened to me was because (a) the backup was actually messed up (check folder size) probably due to corruption or (b) my SD card was out of space. I've always renamed my backup set similar to yours (I append the ROM name) and it never affects the restore.

Are you using touch or standard CWM? I wonder if this only happens in touch version. I will try this in the next few days.
I changed the name of one of the backups I created with CWM touch and it restored fine using touch. I suppose my earlier problem may have been trying to restore a backup created with old CWM using touch version.
well since you are on the subject cwm touch im making a nanadroid backup of my current ics rom right now as i speak. i started about an hour ago and its still on the backing up data part. when i used the older version to make backups i dont remember it taking this long. have any of you had cwm touch take well its been a little over an hour now? i do have more apps on my phone now than i did the last time i made a backup would that matter? should i just jerk the battery out and go back to the older version of cwm i was using? thanks ahead of time for any advice / help you may give i would appreciate it. im trying to backup this rom cause i want to flash a different modem cause the ics modem form the leak is crap and need a backup in case it dont work..

If you are using sk8erwitskil version of the CWM touch (ClockworkMod TOUCH 5.5.0.4 v3.5) then most likely you didnt follow one of the directions on the front page. This is a known issue. Here it is again. You need to create that file on the location you backing upto.
For CWM to recognize the .hidenandroidprogress file you need to boot into CWM and go to mounts and storage>>mount /sdcard then go back to backup & restore and make a restore and it should work everytime (as long as you do the steps in that order and you have the .hidenandroidprogress file in /sdcard/clockworkmod & /sdcard/external_sd/clockworkmod folders)
There is a known bug in ClockworkMod 5.5.0.4 that long file names can POSSIBLY cause backups to hang. There is a solution/workaround:
•boot into recovery
•try to make a backup (no matter if it passes or fails proceed to next step)
•either through terminal emulator or through adb run the following command EXACTLY:
Code:
touch /sdcard/clockworkmod/.hidenandroidprogress
•if you are backing up to external sdcard then run the following:
Code:
touch /sdcard/external_sd/clockworkmod/.hidenandroidprogress

Not sure, I used that for awhile but then went back to the other touch and Ive had those two files still in my directories.
I would go ahead and create those two files (one for internal SD and one for external SD if you got one you are using that is) and try it again. Make sure you call that file exactly the way it is, or copy/paste the code identically if you do it through ADB.

Well the crazy thing is after sitting there over an hour waiting I finally took out the battery and even though it never said complete all the files are there but I still don't trust that it made a good backup so I deleted those files tried putting in the code above and it still would not work so I flashed back to version 5.0.2.0 thats not touch and it made a perfect backup in under 2 minutes. Might be one of those it just ain't gonna work right on this specific phone thing or it could be the little green gremlins at it again lol... who knows.. I'll just wait for new version of touch to come along and try it. It won't be long till a newer greater version comes along as fast as technology is going today.. thanks for the help. I'm learning more and more each day from you guys on xda.....

Not sure if this is the cause of the issue but for nandroid backups you can't make a folder name with spaces otherwise you will get an md5 sum error. Try renaming the folder with underscores instead of spaces
Initial phone stats: DS Mod 1.55.531.3, hboot 1.45.0013, s-on/unlocked via HTC unlocker.
I'm trying to update my own phone to 1.63.531.2 via the PG59IMG.zip file found here, http://forum.xda-developers.com/showpost.php?p=17424340&postcount=24 , but I'm running into problems applying this update and keeping it after restoring a Nandroid backup. It would be a huge amount of work to set up my phone from square one, and I'd like to avoid the process if at all possible.
The steps I've followed (twice, now, with no joy) are the following:
* apply the update through the PG59IMG.zip
* flash CWM 5.0.2.7
* flash Superuser
* restore most recent Nandroid backup
* flash 1.63.531.2 boot image (for wi-fi fix)
And this puts me back at my starting point, with the 1.63.531.2 update not applied.
I know I'm going about this the wrong way, but I can't figure out the correct method to make this work. The fact that I flashed the DS Mod 1.55.531.3 ROM back after unlocking might have something to do with this, however, I just can't nail down why. Really could some help to make this work.
TIA for any suggestions --

hey, real quick, after flashing the 1.63.531.2 update, instead of restoring your full nandoid of 1.55.531.3, go to 'advanced restore', choose that nandroid, and choose only 'restore data'. that will put all your apps and data onto the new update, rather than flashing you all the way back to what you had before.
you could also backup and restore your data with an app called Mybackup Root, or some people use Titanium Backup. I personally like using the advanced data restore in CWM, or else Mybackup.
Yogi, I thought your suggestion would be a smoking gun. However, I'm having the same problem as described in this thread: http://forum.xda-developers.com/showthread.php?p=25431819#post25431819
Might you have any suggestions for addressing the md5 problem? I'm coming up empty...

yeah, come to think of it, I've had that problem before as well. did you try what xmc suggested? also, perhaps try the Modaco 4.0.0.9 version of CWM to do the advanced data restore... if my memory serves me, I have had more success overall with that version. unfortunately that's about all I got!
the other sugestion would be to flash your full nandroid, then use Mybackup Root to back everything up. then after updating, DL the app again and restore.
good luck and keep us posted!

Yes, and for the backup I want to restore, all the md5s are the same between the files and what is listed in the nandroid.md5 file. So, the method XMC suggested really doesn't do anything.

I'll keep this as the last resort, because I'd rather not have to download an app for just this purpose. Nandroid backups have served me fine so far. Call me a minimalist.
I'll try Modaco and see what happens. Thanks much for the idea to try.

King Cheetah
Sadness
Using Modaco didn't work. Although the Advanced Restore sees the file and appears to run successfully, it says it can't find a data.img file and an Android.img file, so it doesn't restore the info.
So, I guess it's down to trying Mybackup Root and see what happens. Getting tired of redoing this process over and over.
Why can't things "just work" in these situations?

fastboot erase data

The problem with this is the file "data.img" doesn't exist in a Nandroid backup. As I stated in my previous message, the Advanced Restore process tossed up a message that the file didn't exist (which is correct).
The files within a given Nandroid backup folder are the following:
.android_secure.vfat.tar
boot.img
cache.ext4.tar
data.ext4.tar
nandroid.md5
recovery.img
system.ext4.tar

I would love to try this, but since the 1.63 update is a PM59IMG.zip, I can't open it with a zip file manager--it throws up a "central directory not found" error. Unless there's another program besides 7zip that's needed to handle this type of zip file...
Edit: I just realized that, as you can see from the file list above, a Nandroid backup also doesn't have a "system.img" file--it has a "system.ext4.tar," but not "system.img." So being able to pull anything from a PM59IMG.zip file is a moot point at this juncture.
Banging one's head against the keyboard does little constructive good, but it's really tempting at this point --

Using the "Explore" option from the right-click context menu in Windows Explorer gives the following error: "The Compressed (zipped) Folder is invalid or corrupted." (Since archive files on my laptop are associated with 7zip, this is the only method by which I can access Win XP's native archive file handling.)
This has been the case with all PM59IMG.zip files--they don't register as normal zip files.
Thanks for the suggestion, though --

Nope, not corrupted because it works just fine to update my phone to 1.63 (as stated before, I've done this twice now). Also, that's the exact same source from whence I downloaded my copy of the file. The PM59MG.zip for 1.55.531.3 gives exactly the same error, and I used that without difficulty as well.

Use winrar to open the PG59IMG.zip files - that's what I used to make all the custom ones with, and also what I used to open the leaked ones we started from.
You won't be able to edit existing leaked ones, because they are locked and have an HTC signature.

Thanks for the pointer, Blue, and I'll keep this in mind. But as I added to my previous post (#8), I realized that a Nandroid backup doesn't have a "system.img" file--it has a "system.ext4.tar," but not "system.img." So being able to pull anything from a PM59IMG.zip file is a moot point at this juncture.
I think I'm going to have to wait for a 1.63 ROM that can be installed through CWM rather than the PM59IMG.zip method. The DS Mod 1.55.531.3 worked well for me, and all apps/data were just there after I flashed it. Maybe I just got lucky with the process I followed previously, who knows?

No prob, didn't read through and shot from the hip on the last post I saw, out at dinner and skimming the forums on smoke breaks
Sent from a digital distance.
does anyone know the deal with the implementation of tar backups? I think that came into play at some point, and I wonder if that has anything to do with anything.
I just checked a backup I made with the Modaco CWM, and the files in it are all .img files, including data. and I know for a fact I have done backups and advanced data restores with that recovery. it would be a hassle, but if you get re-energized you might make the backup and do the restore with Modaco. definitely would be a hassle if it didn't work, but you could also make a backup with Mybackup, and have that ready too, as well as probably have a data.img to try and flash thru fastboot like xmc suggested.
anyway, hopefully we'll get this all sorted out. take it easy!
well .tar are used ever since cwm started working with ext4....maybe imgs are only ext3 or lower or its just inefficient
On that note, I did use the modaco 4.0.0.9 recovery to make the nandroids I pulled the system images from to get the bases from which I de-odexed, and when finished I uploaded to my host and they are the de-odexed bases I posted in dev.
I am pretty sure I went with modaco recovery for that because cwm 5.0.2.7 output tar files and it just saved a step in the process.
If you are working with the .tar files then jump on linux to unarchive them if that's what you are trying to do.
I just ran the deodex process using windows, because the first working deodex tool I found was a windows tool.
Generally I use modaco .9 for nandroids I want to work with in windows, and cwm 5 for nandroids I want to work with in linux.
We're probably leaving the restaurant soon, if we split up I'll actually read back through the thread when I get home and see if I have anything else to add.

[facepalm] Of course! This is why my Advanced Restore attempt with Modaco failed--because I used the CWM 5.0.2.7 backup, which did not have the files Modaco would have referenced. Duh! I wasn't even thinking along the lines of a file type mismatch between the two recoveries. Baka baka baka...

At this point, not a hassle, but the best chance to accomplish this thing with a minimum of fuss and bother. I'll give this a shot right after a bit 'o java. Thank you, Yogi, for highlighting something that should have been obvious to me when Modaco gave the error message that "data.img" didn't exist. Oy!
However, this still leaves unanswered the question of why CWM 5.0.2.7 is tossing up the md5 mismatch error when one tries to use Advance Restore, and that files aren't seen by CWM via Advance Restore until one accesses regular Restore. Paperskye is having the exact same problem in this thread: http://forum.xda-developers.com/showthread.php?t=1624319 . Should this be brought to the attention of the CWM devs? It really seems like a rather show-stopping error for CWM...unless Advanced Restore isn't really used with 5.0.2.7 and the MT4GS. There just doesn't seem to be a good reason for the observed behavior.
Many thanks for your encouragement. I'll report back with results on the next try with Modaco --

KingCheetah
It's a beautiful thing!
Using Modaco for my backup prior to the update, then Advanced Restore of data afterward = perfect restore of my phone environment with 1.63 on board. Done with as little fuss as I was hoping to encounter. Yogi, you get the prize. The only thing I had to manually put back was my custom boot animation, but that's trivial.
I think I'll just leave Modaco on as my recovery for now, since AR is functional with it and CWM 5.0.2.7 is not. Makes me wonder, from just an everyday backup standpoint, is there any real advantage of CWM over Modaco? I wish there was more information on how the recovery module functions on the CWM website--I'd like to read up on it for educational purposes. Guess I'll do a Google to find more.
So ridiculously happy right now. In a stew of things going wrong, at least something went right.

Update 9/1/2012: A user has successfully restored with this method! Continue to "Testimonials" for more info!
Update 9/2/2012: TrevE has now come up with a way to leverage Samsung's built-in restore to your advantage! Read below for more!
Update 9/3/2012: Changed adb commands to reduce Operation not permitted problems.
Thanks to the efforts of some great developers, there is now *possibly* a more comprehensive method to backup your IMEI. While I have not personally tested a restore using this method, a user in IRC has done a manual NVRAM wipe and restored it using this method, without the roaming issues caused by a occasionally-bungled QPST restore or manual IMEI injection. In addition, posts in this thread indicate a successful restore from an actual occurrence of the problem, all without the use of QPST and also without any roaming issues!
Before I go any further, the same old disclaimer still applies; you accept all responsibility for what you do to your own device!
Theory:
The theory is that the S3 has, in the boot process, a routine which is "tripped" when it detects an error condition. This routine is designed to "save" your IMEI by restoring images from two built-in backup blocks. The problem is, it actually does the opposite; for whatever boneheaded reason, the default backup blocks contain dummy images with an IMEI of 0 and no carrier identification. This is why your phone forgets what carrier it's on and what its IMEI number is; the restore routine actually overwrites the phone's only copy of the IMEI data with a dummy. Because much more data is lost than just the IMEI, this is also why a QPST injection (not a QCN restore) persistently leaves you on roaming.
In an initial attempt to solve this problem, users have attempted to "dd", or create an image of, a single block supposedly containing the IMEI when the phone is still in a good state. This is the efs.sbn method that you may have seen. However, upon further inspection, it turns out the IMEI data is actually spread across five different block devices, hence why the efs.sbn method is either ineffective or leaves you on roaming! After the block devices were identified, a SynergyROM team member created an easy-to-use recovery zip that allows you to image these five blocks, allowing you to reflash them should the Samsung boot process overwrite your IMEI! Re-flashing these blocks after they've been crapped up virtually ensures your phone has been fully restored to its pre-IMEI-loss condition, thereby preventing roaming or data issues seen consistently with a manual injection, or intermittenly with a QPST restore. You do not need SynergyROM to use this tool; I've done it from full stock.
But wait: there's more. About a week after the development of this tool, several unused boot entry points were discovered that revealed a way to control Samsung's built-in "safety" feature and actually make it work properly! Two backup blocks were put in by Samsung themselves; "fsg" and "backup". The great news is that, although these images may contain dummies by default, you can instruct the bootloader to write your good NVRAM data to them so that the good data is what's written to NVRAM in the event of an error. That is, instead of restoring a dummy image over your good IMEI...it restores a good backup instead and you don't lose a thing! How awesome is that?
Developers are now recommending a new IMEI backup regimen, leveraging Samsung's built-in IMEI backup and SynergyROM's manual backup, together with an optional QCN backup you can do for good measure. Of course I can't make any guarantees, but doing this backup should leave you in such a good spot that almost nothing can total your IMEI or leave you in a roaming state. Here are the new instructions on how to backup your IMEI, iron-clad. Do Parts A and B, in order, C is optional but will give you added peace of mind.
Backup:
Part A (Samsung's built-in backup):
1. If your phone does not have Terminal Emulator installed, you will need to use ADB. Download and install the Android SDK platform-tools for your platform. This is a bit non-trivial as it requires the installation of the Android SDK, however, you can find a guide for installing adb here. After installing, open a command prompt and navigate to the "platform-tools" folder within the SDK, where adb is stored. If you need additional help on this, simply ask in this thread.
If your phone is rooted and has Terminal Emulator installed, you don't need to do any of this. Simply open up the Terminal Emulator and go to step 2.
2. For ADB: Connect your phone to the computer and ensure it is in "Debug Mode" (Settings->Developer Options->USB debugging). Then. in the command prompt, type the following:
Code:
adb reboot nvbackup
For Terminal Emulator: The actual "beef" of the command is the "reboot nvbackup" line. Therefore, if you have Terminal Emulator installed, you can just run the command straight off your phone. Enter these two commands from the app:
Code:
su
reboot nvbackup
3. Your phone will reboot and copy the contents of two IMEI partitions to the two built-in backup blocks. You may see tiny blue text on the bootloader screen indicating that it is copying.
4. Allow it to finish and then reboot back into Android. The "fsg" and "backup" block devices now contain your IMEI information as they should have in the first place.
Part B (SynergyROM's "Plan B" manual backup):
1. Download the attachment at the bottom of this post. This is an update ZIP you can run right from recovery.
2. Reboot into recovery. On stock this can be done by turning off the phone and then turning it back on while holding UP and HOME.
3. CWM: Use VOL UP and VOL DOWN together with HOME to select "install zip from sdcard" then "choose zip from sdcard". Navigate to the folder you downloaded it to (most likely Download/). Select the zip you just downloaded to "flash".
TWRP: Touch "install" and navigate to the folder you downloaded the zip to (most likely Download/). Swipe to confirm flash.
4. Allow the backup to complete successfully. "Flash" is a bit of a misnomer; this is actually just a script that will safely backup your EFS and radio information to /sdcard/synergyrom/backup without touching your ROM at this point. When the script completes, reboot.
Part C: Backup with QPST:
Once the gold standard of IMEI backup, this method (in my opinion) should now be done only in the event of an unlikely complete catastrophe where neither Samsung's built-in restore nor SynergyROM's restore works. Simply follow the instructions here for extreme peace of mind; you don't need to do this if you don't want to, but I personally did.
Restore:
Do not do this unless your IMEI has been lost!
Performing Part A of the backup should ensure that you never lose your IMEI in the first place; the theory being that the Samsung built-in backup now has a good image to restore itself, as opposed to a dummy image. However, things may still happen. If you've still lost your IMEI, perform each of these methods in order of priority, "A" being the first.
Restore Plan A:
Run the following command from adb, just like when you backed up (have Android SDK installed, connect phone, and ensure USB debugging is enabled):
Code:
adb reboot nvrestore
This method triggers Samsung's built-in IMEI restore; except this time, you got good images on your side. Simply allow the phone to restore and reboot itself when completed. NEVER PERFORM THIS COMMAND WITHOUT DOING PART A OF "BACKUP" FIRST; THIS WOULD RESTORE THE DUMMY IMAGES INSTEAD AND WIPE YOUR IMEI!
Restore Plan B:
Sometimes a fluke happens and the nvrestore does not work. That's why this one is Plan B and not Plan A. Good thing you did Part B of "Backup"! Rather than instructing Samsung's bootloader to restore your NVRAM, this method will do so manually from recovery using a manually done backup.
It's just like when you backed up, except now you want to flash the zip containing your NVRAM info that the other zip built for you. This zip is located in /sdcard/synergyrom/backup. Simply navigate to this path and flash the zip beginning with "keybackup"; this will write images to 5 block devices from a time when your IMEI was all good. Reboot the phone; if all went well, you now have your IMEI back with no roaming!
Restore Plan C:
Both methods above may fail you in extremely unlikely circumstances. At this point, you'll need to try using QPST to get your IMEI back. If you did Part C in "Backup", you can follow instructions in that same thread to get you back up and running. In most QPST restores, you shouldn't have any issues with data or roaming.
Restore Plan D:
The planets have lined up, the Cubs have won the World Series, and all three above methods have failed you in what is surely a sign of the apocalypse. Far more likely, though, is that you didn't have a backup of anything and your IMEI is gone for good. The good news is that you can still get your phone working; the bad news is that you'll be stuck on roaming and may have problems with data. You'll need to perform an "IMEI injection" which is a kludgy last-resort restore method that manually writes the IMEI to NVRAM; the link I provided in Part C of "Backup" will tell you how to do it.
Testimonials:
This method has been tested good by the following users in this thread!

Just flashed CM10 09-01 nightly and lost data, confirmed I lost my IMEI. I had used the process in the OP a while ago to backup my IMEI. Just would like to confirm that I just flashed the backup it created and happy to report all is well again. Thanks for the post of this tool........saved my butt......

The other trickery we ran into is partitions do not like to be written to for whatever reason outside of package_extract_file right outa the zip. dd'ing directly back failed over and over, I have no clue why, poor esc must have flashed 100 zips before I gave up looking into it. So the updater zip restore uses only package_extract_file, actually writing partitions out properly. I have high hopes that it will actually work, but until tested otherwise do as many types of backups as you can

So will this work on any ROM?

Worked on CM10.
I'm all for redundancy of backups, so here's hoping this method fully works when restoring. I have not experience a loss of IMEI myself, but I definitely want to be safe. I know the original efs backup method was proven to be an incomplete backup, but I thought the QPST NV backup method was proven to work? Are you saying that restoring with tthe QPST method (where you have an NV backup before you lose IMEO) does not work and will still having roaming issues?
At any rate, it will be interesting to see if this is the "one true backup" to rule them all for IMEI. So basically, you flash the zip in recovery and it creates another zip with the backed up contents. And in the event of an IMEI loss, you just flash the new zip and should be good to go? At least, that's the theory, right?

Confirmed successful backup using CWM.
I can confirm this backup method works using CWM.
I first tried it with TWRP via Goo Manager and the script didn't execute properly.
I tried flashing the file while still in TWRP and I couldn't even find the zip file anywhere, user error I'm guessing.. lol.
So I flashed CWM over TWRP via ROM Manager PRO and flashed the zip file with CWM via ROM Manager PRO and the zip script executed nicely. I found the backed up zip file where the OP said it would be.
Here's to hoping I never have to use the backed up file, but it's good to know I have it there if needed.
Thanks again OP!

This should work regardless of ROM as it is a recovery zip. I've tested it with CWM: I've never used TWRP so I don't know how well it would work in TWRP.

I've tested a backup successfully on full stock, rooted. The backup will be stored in a folder called "synergyrom" but this just the name the tool gives to the directory (as the tool was created by the Synergy team) and has no impact on function or dependency on SynergyROM.

QPST method is not perfect; it is better than a simple IMEI injection, but the boot bug writes crap over much more than just the IMEI. This is why either method may leave you on roaming (althogh a QPST restore only sporadically causes roaming). In addition, various DRM keys may be erased as well, leaving you potentially unable to play back HDCP/PlayReady titles; QPST does not restore these.

That's correct. When you "flash" the backup zip, nothing actually is written to the ROM as far as I can tell; it runs just like a script/batch file and saves your backup zip to /sdcard/synergyrom. The tool itself creates a new flashable zip in this directory, one that does modify your unit, which you can then use only in the event that the bootloader craps up the NVRAM.

i know i know lol I've been hesitant because of the IMEI issue and the phone is pretty damn good as is. But I'm slowly leaning towards flashing custom roms to get rid of the bloat, and since there are more ways now to hopefully restore the IMEI in case its deleted.
I am looking for an application that can make my nandroid backup without having to go into recovery. But I am not sure if the backups that are created with the apps in this thread title are compatible with clockwork mod.
So, my question is:
Can clockwork mod recovery read the nandroid backup made by those online apps (Online nandroid backup pro or obackup nandroid)?
Thanks
Most likely not. Make one and try it before you rely on it

i guess nandroid backup made by a tool must be restored by the same tool.
note that when backuping with cwm a md5 file is created, and when restoring, md5 of the backup must match
Why do you want to take a backup without going into recovery if you don't mind me asking?

no worries. i am glad you asked since i can be doing something i am not supposed to do (I am new to all this stuff).
the answer to your question is that i stumbled upon the possibility of doing the nandroid backups without having to go into recovery mode. plus the convenience of uploading such backups to the cloud and doing them automatically/periodically. both Online nandroid backup or obackup nandroid would help me with those features but then i thought "what if the clockwork mod recovery does not read those files?" that is why i made this topic.
is making an online nandroid backup bad? if it is better to make it inside the recovery fine by me. it does not take that much time either. i guess i just have to get used to make them and not forget.
anyway, looks that those online backups are not usable when in clockwork mod so i will not use those apps.
in the mean time, i have been looking in the rom manager premium app. it is made by clockworkmod.. can that application be used for online nandroid backups? maybe these are the same as those made inside the recovery? if so, i could use this application for the nandroid backups.
regards and happy new year!
You can try to make backups both ways and then ţry to restore the 3 rd party backup with CWM. If failed, you will have the proper CWM backup to restore as well. By the way, original backups are accessible to your device as files and you can simply sync that folder to the prefered cloud service - dropbox, box, drive, etc.

The method I use will only work with a CWM based recovery. I find Philz best. This is because I am using extended commands, which are proprietary to CWM.
I wont go into detail on the foldersync part. All I will say is you set up a folder pair between your sdcard/clockworkmod/backup folder and your backup location, which could be a NAS, Computer thats always on or a Cloud location. I set mine to delete the backup from local storage before it takes a new backup and also afterwards. I also set within foldersync that they only run on wifi.
I have the 3 following profiles:
1.Nandroid Copy Pre
2.Nandroid Backup
3.Nandroid Copy Post
Pre and Post are identical in that they run the foldersync task. The only difference is the time they run.
I run the 3 profiles at these times on a Saturday:
1. 02:00 - 04:00
2. 04:00
3: 05:00 - 06:00
So basically, that is foldersync to NAS (deleting backup), taking backup, foldersync to NAS (deleting backup). I do this as I am tight on space. On my S3, I used to keep 2 backups locally, deleting the oldest before taking the next one.
So you're probably wondering what happens in the task for profile 2. Both actions are created using the Script > Run shell
Code:
1. sh /mnt/sdcard/clockworkmod/nandroid.sh
2. reboot recovery
1. calls a script called nandroid.sh as you can see. The contents are below:
Code:
# Set date and time
now=$(date +"%d_%m_%y-%H%M")
# Writes command for cwm based recovery to read
echo 'backup_rom("/data/media/0/clockworkmod/backup/'$now'");' > /cache/recovery/extendedcommand
That's it in a nutshell.
If you wanted to, you could run the task 1 before which does a delete of the backup and the sync after (its 2 for redundancy) to just sync without delete, always keeping 1 backup on your device.

easy? we surely have different levels of knowledge for sure. but i gladly take your help if you are willing to use the time for it.
lets see if i can sum my difficulties first.
- in your post you mention Philz recovery. so i googled it. i am not sure but is this the "upgrade" for rom manager premium where you can use touch? if so, i do not mind buying that upgrade (because i do not have the touch upgrade, only bought the premium rom manager app).
- i still do not have foldersync but that is probably very easy to configure so only thing left for me is to buy the app. no problems here.
- tasker profiles. never used tasker but already bought it because of its functionality. i tried to make a custom profile on my own and it did not work. been reading help so i can figure out the app and how to program it. it might take a while though
i believe thats it. like you see, i still have a long road ahead of me. if you have patience and want to provide help i will surely be thankful. besides, i am sure a lot of other people out there will find this topic helpful so you will not only be helping me

Its not as long as you think
Philz touch is a cwm based recovery. Its like cwm but much more. Its free and can be found in our nexus 5 "android development" forum here. Should be easy to spot. Thread is posted by me It will still work with rom manager although i prefer to not have rom manager.
Foldersync has a free version too by the way
But let's break it into byte size chunks. Firstly decide if you're willing to flash philz recovery via fastboot or not. You don't have to. Cwm is fine for now.
Next step will be to create profile 2 and task. Let me know when you're ready for that. I can't promise you quick responses but i'll walk you through it.

Hello. I have subscribed your thread about philz recovery. I am thinking of installing the zip file from clockwork mod recovery. Do you think it will be OK doing that way?
Why do you think it is better to not have rom manager?
Do not worry about "quick answers" , that way you give me time to read and learn. Going to read your thread on recovery, might learn something there
Regards.
Yep, that way is fine to flash
Personally I feel that apps and tool kits that do things like flashing are detrimental to the user experience. Doing things manually is the best way to learn, ergo the best bet in case you ever need to get yourself out of trouble. The manual steps are good to know so it's always best to be familiar with adb, fastboot and recovery yourself, instead of having apps and kits that manage these crucial steps for you.
Hi, first of all, thank you for reading me.
I think i messed up big time.
I had Havoc OS 4.1 installed since more than a year and it was kinda messy e.g. the sim card card wasnt recognized anymore so wasnt able to make calls because i played to much in the settings.
Having some stupid but incredibly addictive games on this smartphone i decided to keep it like this and since i'm a complete n00bs and being afraid of security risk of rooting my device i never rooted it.
Big mistake.
So, recently, one games needed an update (like they all do at least once a week) and since i'm anti-google/f***book (no comment please) i nvever saved my progress in the cloud and "that" game required absolutely an update.
I installed the update from an alternative apk source and , (applause if you want and laugh), it screwed up the game.
Now the nightmare begin.
Since the device isnt rooted i made a backup of /data partition. Gone crazy and before i might explode in an uncontrollable fury and madness i used LMSA to rescue the phone. And myself, lol.
Now i have stock android and i am googled to the bone. My butt hurts. My head too.
THE (first) simple question is : how can i restore this backup because i have the error 255?
Notes and observations; logically i would say because the device is back with stock rom and doesnt have the same os/rom installed and/or the partition and whatever is not the same wich may explain the error 255.
SECOND QUESTION: can i extract/uncompress this backup and take the precious data wich is my games progresses and restore it somehow?
I know i have to give as much information possible but i dont what else to give. If you need logs, or everything else just say it nicely and i will give it to you with immense pleasure.
Oh yeah, model : XT2113-2 5g Kiev RETCA 128gb a/b type and maybe was crypted before because twrp asked me the password to make backup or else.
Thank you in advance and i really hope somebody would help, if not i just loosed 1.5 years of stupid gaming because i messed up like an idiot. (A lesson well learned, the hard way...)
Thank you so much for not answering this simple question.

These precious brief and concise 2 lines of a simple answer is immensely welcomed.
Wich point me to reply that to my knowledge i interpret it as a security chip with big chances that its in relation to the knox technology.
It also point me to ask WHY, if i cant back up because of that, why/how is it possible to install a custom rom or gsi (sorry i still dont make the difference because i dont understand it) on this very protected smartphone?
That must explain why i had problems trying to root it and fail each time.
Finally i think that i should use another device for android gaming since i dont want to depend on f***book and google.
Thanks again sd_shadow. Even if it was a very simple answer it enlightens me alot.
Note: sorry for my bad english.

This error code means that at some point your backup of /data could not be extracted further. But for more detailed infos you must provide a recovery.log which will be generated when doing a backup of e.g. /boot.
>>> Please DO NOT copy+paste it here!! <<<Rename it (recovery.log > recovery.log.txt) to be able to upload it within "Attach files".

Yes, use Titanium Backup (TB). Although it's very outdated it still features a restore of single apps out of a TWRP backup. Here's how you do it:
1. IMPORTANT: TB will only search for TWRP backup files on internal storage!! Use the default path created by TWRP, e.g.: /sdcard/TWRP/BACKUPS/ZY322V8K28/2023-04-08--06-53-20/
2. Install and open Titanium Backup.
3. In the upper right corner tap
MENU > scroll down to "Extract from Nandroid backup" > choose your backup folder
##############
Notes:
- Usually a TWRP backup of /data consists of several parts (data.ext4.win000, ~win001, ~win002 etc). TB requires all of them (or at least those ones with the /data/data/ path inside).
- If you are facing this error message:
Could not find any data in this TWRP backup
then your TWRP backup is compressed with gzip. To decompress it you must rename the file
data.ext4.win001 > data.ext4.win001.gz
and extract it with any archiver tool, e.g.:
- ZArchiver (Android)
- 7zip (Windows)
- Problems finding any TWRP backup data with Titanium Backup? Then please check your path!! (see above section)
Good luck!!
Thank you very much WoKoschekk i'll do it as soon i'll have the time for since i'm working today.
Thank you so much again, i'll keep you posted with logs and such.
I'm sorry i didnt gave news since, i'm not doing very well.

1-With all the instructions you gave me is it worthy to continue because when i did the backup i wasnt rooted?
2- i'm sure i read many time to use Titanium Backup (wich is a paid app?) i have to be rooted or have root access.
Ultimately, how can i be rooted if there's a chip preventing me to do so?
I'll keep you posted when i'll be of better health, thank you.

TWRP backup = *.tar archive
TB unpacks the needed app's data and nothing else. You must be rooted to have access on /data for restoring your apps. But for the backup process it doesn't matter if you were rooted. Root is part of your boot.img.

TB is for free. But a paid version unlocks additional features (not related to the TWRP restoring feature).
And yes... root is mandatory for TB. As I said before you must have r/w access on /data/*.

Which chip?? You already have root access via TWRP. Magisk is only needed in system and just a patched boot.img (custom kernel).
Get well soon!
WoKoschekk thank you for this insanely fast reply.
All those answers and infos have now a gigantic value for me, if only i knew that before.
To describe a bit more my situation i slept only few hours since 5 days, vomiting, heavy coughs and fever.
I'm sure i'm not supposed to but i will anyway, i engage myself and promise to reward you (in particular) and others for the help you're bringing me. It wont be much but very important to me.
I'll go try to get (again) some rest. Just before i go, why was there a mention about my device;
"
The problem is it's a Motorola with a Qualcomm chip.
If you find a solution I would love to see it.
"
I dont ask you (WoKoschekk) or other to explain in the most explicit and endless details of what is exactly this "chip" and all the history that goes with it cause i dont want to be a pain but just why it was mentionned. Only, why?, it has ben mentionned.
I cant wait to get better since i finally see possibilities to get back those files.
Have a nice week-end and thanks again.
@Kerplunk83 To reveal the mystery behind "the chip": Motorola released two variants (Snapdragon/Mediatek CPU) of this model. Since the CPU largely determines the system structure, building a functional TWRP for both of them is very challenging. It seems that TWRP for the SD's variant got some bugs while the MT's variant runs more smooth. Due to this fact the error 255 is caused by something that you weren't be able to fix.
Regarding your problem: To restore an app and its specific app data you need the proper permissions to write in /data/data and /data/app. For this permissions you either need TWRP or Magisk installed. TWRP seems to be unable to write in that specific directory. On the other hand you don't want to install Magisk. I'm sorry but with this setup your problem can't be fixed.
Just out of curiosity, could you provide me a recovery.log showing error 255 during the restore process?
Please DO NOT copy/paste the whole log and post it here!! Instead of this you should rename the file (recovery.log => recovery.txt) because a file called *.log isn't allowed for upload. But a *.txt file is.
Options to create a recovery.log:
1. adb pull /tmp/recovery.log
=> copies a recovery.log into your ADB/fastboot folder
2. Do a backup of sth. like "boot" because the backup process will create a recovery.log by default
3. TWRP mainscreen > advanced > create log (kernel log isn't needed here)
=> log is stored on the default storage (internal or external) that you have choosen for backups etc.
