[Q] Can you rename Rom backup folders?

noob question i know however just a quick one,
can you rename nandroid backup folders with messing up md5sum ?
i load a ton of roms on the regular [a junkie i know] basis and get flustered when i have tons of backups but they are all dated

great question i also would like to know never had the balls to try cuz it says something about messing it up i know in rom manager u can under manage and restore (i think) also rom manager doesnt see ur cwm backups i usually go through ando zip but yea id def like to kno

I don't know if you can rename the folders themselves, but you CAN rename the backup file itself. I use Root Explorer to do this. Just make sure you don't put any spaces in the new file name. You can use dashes and underscores to separate words and numbers, though.

Someone in the past said you can download mand5 to generate a new md5 sum, but I haven't tried it.

@visedmonk do u think andro zip will work it says it will let me rename then i click on that and it says change to file extension can make file unusable and i dont space any letters for instance il put cm for (cyanogenmod) rite next to the numbers havent had the balls to try it

I dunno. I've never used andro zip. Only one way to find out...
But seriously, it should work. To be safe, though, make a copy of the file you want to rename and place the copy with the unaltered name on your computer or sd card or whatever. Then you can rename the file and see if it works. If it does, great. If it doesn't, you still have the backup you need.

Don't know if you're using "nandroid" generically to refer to both the true nandroid as well as CWM but I rename CWM backup folders all the time and have never had trouble restoring them. I've done it from ROM Manager, via a file manager and also via ADB.

im talking about the folder not the actual files in the folder.
i just want to organize my roms so i can always jump between each

@suprah name it like this ex, 2011-06-16.05.57.13.....
you want...2011-06-16.05.57.13gingerbread ? rite well when i try that in andro zip it sayin it will make file unusable.... n i guess i will have to try and i always used to use rom manager and just go to manage and restore backups but its different with this phone especially cuz rom mana doesnt see cwm i guess?

Yup, that's exactly what I'm talking about. I rename the folders all the time and have no problems restoring.

alright welp as long as you rename the folder without any spaces, then there would be no problem with restoring nandroid backups

nice nice will try soon cuz yea i have like 6 backups on here n was writing the date down with a name lmao

I renamed the folder once and couldn't restore. It was making a reference to the md5 file.
What I did to fix the backup is rename the folder again but this time without spaces and then it let me restore without any problems.
Now my Nandrioids are all organized
Hope that helped

the stock rooted nandroid restore that's posted in the dev section is renamed to LG-P999-V10f. it's not the typical date format. and alot of people have used it. so the answer is ....yes.

Could be there's a coding error in the recovery code and stops parsing the directory name when it hits a space. The md5 file only references the individual files not the directory.
In general it's better to stay away from spaces in file and directory names. Back in the early days of *nix spaces were verboten and there are still some vestigial issues lurking either in the code or in the coding habits of some people. It's rare but it does happen. Hyphens, underscores, periods are all OK though.

If after you rename the folder you get an md5 error. This http://forum.xda-developers.com/showthread.php?t=714114 can help you fix it.
BE SURE AND READ THAT POST COMPLETELY
It's imperative that one not generate an md5 sum for a nandroid that is actually corrupted. That will wreak all kinds of havoc on your system.
ONLY PERFORM THE ABOVE IF YOU KNOW ITS NOT RESTORING DUE TO A NAME CHANGE
EDIT: For the record, the above commands can be performed from terminal emulator if you know what bits to leave out. Saved me a few steps.

I rename all of my nandroid backups. They are easy to get confused otherwise. The only thing I change is the year in the date, and leave the month/day alone.

Yea I downloaded the Stock Nandroid and loaded it. I renamed the folder and got a MD5 error. Now I'm not sure it if was because of the rename or because it was a bad download to begin with.
I think I still have the file on my pc and possibly find the MD5 checksum before copying it over this time.

how to rename CWM backups?

I have been palying around with various Zoom configuration. As I get one close I do a nandroid backup with CWM Recovery. I would like to be able to rename them with discriptive names so that I can find a specific backup when needed. Every time I try I get an MD5 sum error.
Does anyone know how to rename a backup and fix the MD5 sum?

You will need a file manager, such as Astro or what I use, Super Manager. Your nandroid back ups will be under folder "external 1" , clockworkmod, backup.

It's all in the file manager
I use root explorer. One thing to remember is that you can't use certain characters. I don't know exactly what they are, but if you only use what are in the original as far as punctuation you should be all set.

Use a md5 checker and check the whole folder, find the md5 file and open a text editor and add the md5 you just got in place of the old one
And if you put any special characters in the name or spaces you will get a md5 sum error
Sent from my ADR6400L using Tapatalk

the easiest way is use root explorer and stick to numbers and alphabet characters as much as possible. it will handle the md5 for you. just renaming the files with a file manager will ruin the backup.. DONT DO IT. I found out the hard way unfortunately.

As a test, I copied a CWM backup folder from my phone to my Windows PC. I renamed the folder without spaces or special characters and then copied the entire folder back to the phone. Upon restoring using CWM 5.0.2.7, it successfully passed md5 test and restored. I then rebooted with no problem.
I also compared the md5 sums in the nandroid.md5 files from the original folder (before renaming) and after renaming and they are identical.
The key is to avoid spaces or special characters; use underscore "_" instead of spaces in the folder_name.
I hope this helps!

you can use - instead of space
md5 fail with space, if rename again it will re-work, data is NOT ruined if you rename

[Q] Generic Imei number

Hi,
for some reason i lost my Imei number. Im not sure when or how, but i would guess it was due to flashing.
Now i do have a backup of my efs folder, but somehow putting that one back doesnt work.
I get the following error in my nv.log:
Backup NV restored.
"MD5 fail. Original MD5 '17f88xxxx etc'
Computed MD5 'fbe9xxxxx etc'
Anybody with a solution to this?
I was thinking it might be because with ICS my radio was changed to the new one, so it makes a different MD5 checksum. Does this make any sence at all?
[edit]
ok this is really weird. Apperently ICS causes this. When i restore a nandroid back to GB and restore my backed up imei files, they stick and i have my imei back. As soon as i go back to ICS the problem is back.

If you're rooted, use Root Explorer & navigate to efs folder, then delete your nv_data.bin file, then rename your nv_data.bak file to nv_data.bin, therfore changing it from a bak file to a bin file, then reboot & see if this helps! If this fails try this technique here: http://www.youtube.com/watch?v=JqLK_2I-SBM Works with nexus s!

thanks for the ideas!
However, i dont have any bak files. I dont think i need them, since i do have the original .bin file.
The original does work, but in ICS it doesnt stick. As soon as i reboot its back to 00049 again.
In GB it does stick, but obviously i prefer to stay on ICS
Very weird problem.. cant be the only one having this issue?

You should have bak files!? bak files are for recorded changes! You say you have a backup of your cfs folder? if you do, open that & do as I mentioned, then try repacing that folder with the one on your device, reboot & see if that helps!

Well as I said, i have done that and it does work in ics... Until i reboot. Then its back to 0049...
In gb it does stick after rebooting, which seems strange to me.

not an ideal solution but why not just script the file copy. so when you reboot you dont need to do it manualy...

[Q] CMW restore fails - MD5 Mismatch?

I made 2 different CWM backups (Cleanrom 3.0 and CM9 roms). Neither of them are able to be restored to the phone, due to an MD5 mismatch. What exactly does this mean? Is it because I edited the name of the backup folder? I've done this before with my Galaxy SII, and those still restored fine.

did you put spaces in the names of the backups? I had the same problem and it was because I put spaces in the name.

Yes I did... I will try it without the spaces and see if that works. Thanks!

That's probably it. CWM will not restore if the file has any spaces in the file name.

OK it works now, that fixed it. What a n00b mistake, thanks all.

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.
