I tried
adb backup -all
but the resulting file is 60MB, but should be 100GB.
Edit: Some more information:
I'm running HavocOS, but the apps on this Rom are unstable. They are stable for almost 24h every time I flash most recent GApps, but by now I don't really think it's GApps anymore.
Aside from EVERY app being unstable copying files is not stable either. I just copied 150GB of images and videos from internal as well as "external" SD-card to my computer without any interrupt and that worked without any issues. If I try to copy a file from internal to external SD card within the phone, then this works in one out of three tries for every single file.
So next thing is try another ROM, then maybe an older ROM and then search for Hardware defects, before I want to try next ROM I want to create a backup.
There is A LOT of config files here and alot of them are linked to images all over the place, so I will likely have to switch to the backup a few times because if I just save the parts part by part now I will 100% forget a few important things.
This seems like a job for TWRP backup. Oh and btw, I did a TWRP-backup just when I migrated to this ROM, but it is defect! I tried to create a full backup withing TWRP >10 times today and yesterday and it all failed. Oh yes, moving files withing this device is buggy right now. But I can do it via adb, can't I? How?

The app's name is migrate..search on playstore or xda thread
Got it, thank you.
It's not working though for three reasons:
1st: It's not a full backup. I got what I need for migrating, I want a full backup to return to the current state including filesystem, tree and random files. Ideally A full copy of all filesystems which wouldn't fit onto any of the filesystems even if this was what the app did.
2nd: It's not via ADB. Backing up from inside the phone doesn't work as I already wrote.
3rd: Doesn't recognize my SD card (yes it's mounted as R/W) I don't know why I even checked that as the app is useless for my case anyway.

Hi
this is my first post, apologies if I'm going about things the wrong way. I've searched the forum and Google for the problem I'm experiencing but the hits I get back are for specific error and processes. My problem is this:
Flashing to Aurora or Runnymede results in my phone throwing up "the process android com.process.xxxx has stopped unexpectedly, please try again", they vary with HTC and Google errors. I get a lot of these errors (phone, camera, media etc) and then a blank HTC whitescreen. I get signal, however if I unlock my screen the errors pop up - I cannot do anything on my phone at all.
My device is S-OFF. I've successfully flashed MIUI and Cyanogenmod many times without error, and they work without a hitch. I've a feeling that with these Sense roms I'm missing some pre-installation procedure of which I simply cannot find what. What do i need to do to get either of these ROMS working?
Thanks for the help!
Edit: I have installed an app that moved certain items to the SD card that were taking up space on the internal memory. Not sure if this has anything to do with it?

It probably is your problem. The roms you tried has some kind of apps2sd implementation already check the rom thread. Technically you don't have to use any app that move your apps to SD.
I will try that out tomorrow when I have some time.
NOw that I've restored my miui backup, I have noticed that same error pops up when the phone loads and I have to run the App, then the errors disappear. I'll post back tomorrow with my efforts!
Out of curiosity, what's the name of that app you are using to move apps to sd?
Root All to Data2SD (cant post links). I'm finding it difficult to move all the items back to the internal memory.
Just from the description of the app, it seems that it will screw up the set up.
Start fresh. Backup all your apps using Titanium Backup. Copy and save all the contents of your sd to a computer. I suggest you zip the titanium backup folder on your sd before transferring it to your computer, I often get errors about the filenames inside the folder being too long with Windows7 if they are unzipped.
Repartition your sd card with fat32 and ext4 or ext3 (depending on the rom requirement)
Put your files back to the SD card and unzip the titanium backup folder as well.
Flash the rom and restore your apps using titanium backup. Do the app restore by batches. The apps should be moved to the ext partition automatically. Check the rom thread for details on the apps2sd implementation they used. Some require to flash another zip after the initial boot. Just check the thread.

Pretty sure I did, which is why this is baffling me. I would've thought that flashing a new rom would replace all pre-existing required applications
To confirm, in Recovery its Wipe Data/Factory Reset?
Performing a full wipe before flashing has worked! I can get into these ROMs now finally! Thanks for the help!
I feel like an idiot
Nice.
I had the same issues many months back. I was going from LeeDROiD Froyo ROM to InsertCoin GB. No matter how many times I flashed, I got same results as you. Then someone aksed "did you full wipe"?
After that, no more problems!!
can someone help me?
the wonder is my first android and I wanted to learn while before hacking on it ...
last night I did the root and installed ClockworkMod 6.0.1.2 to make a nandroid before flashing a ICS rom.
but I have come some doubts:
1) the nandroid with clockworkmod is done either on internal mem on external sd right? I tried with the internal memory and I did a backup of 17MB ... I have copied to the PC the folder ClockworkMod always 17MB: they seemed to me just a few for a nandroid backup... I did it again ... the same ...
2) then I added the external sd and I deleted the two previous backups from internal mem and redid the backup to external sd ... the process took about twenty minutes (slower then before), and in fact has made a backup of 790mb
3) I try to copy the backup on the PC with the phone attached but it don't work .... I removed the SD card and copied the folder on pc with win7: I did not copy some files because they are "too long" (???)... then I tried to copy it on a pc with ubuntu and makes the copy but when the transfer is finished tells me that the number of files copied is right but instead of 790mb is only 725mb: I need to trust this backup? ?? better to delete and redo everything? I do not want to flash something and do not have a working nandroid...
another question: when I flash a rom and do ALL wipe the sd external is reset? no I think, right? and to put on the contacts and messages and the settings I use those saved using kies or do I need to do a better titanium backup or save contacts synced to gmail?
sorry for the many questions but as I'm a true noob and before I do damage I want to have in mind what I was doing
I'm waiting your reply before flash a rom... thanks

First thing: Why do you need to copy the backup to your PC? I can certainly assure you that the backup is working fine. Just leave your SD card within your device upon backing up. And just leave it there. If you ever really wanted to copy the backup to your pc, well don't get the file size(s) wrong. They will certainly be different since the systems you are trying to copy the files to uses a different file system. So it's normal for them to have different file sizes. To add to that, the CWM uses generated MD5 to confirm that the backup (it's related files) are correct before it will restore a certain backup. If something is wrong or the backup got corrupted, CWM will not continue in restoring it.
Second: when you flash, your personal files in your sd card will remain intact. Flashing (may) be only wiping an SD-EXT if you created such partition in your card since apps uses this. So don't worry.
For most customized ROM, I'm afraid components regarding the communication of your device and Kies won't be integrated since devs prefer your system to be our of bloats as possible. So upon flashing a custom ROM, you might not be able to use Kies anymore. In flashing, internal data such as contacts, messages, APN, wifi(s), etc. will be erased as the system will be erased. So;
For your contacts: Sync it with Google or export them to our SD for later import.
For your APN and messages: There's an app in the Play Store that allows you to backup and restore them.
The titanium backup is a very good tool too. Use it.

thanks a lot bbmadzky, I understand what you say
I wanna copy backup in my pc to have a secure place where put the first nandroid of my wonder with stock rom as I have bougth it external sd can be corrupted or deleted and have a genuine nandroid of my phone I think is better
just do another backup to ha the certainty to have a good backup and now can I try to flash my first costomized rom
thanks a lot dude
ciao
It's been a pleasure in helping you with your doubt. Happy flashing and don't ever forget to do a nandroid backup.

This reply may be too late in coming...but I'll post it anyway. First, the size of your created nandroid....17mb.....WAY too small....the size of the backup I made was +/-800mb.
Second....if you REALLY have to copy it to a PC, zip it with minimal compression first....I found from personal experience that it copies MUCH more easily and safely....
Finally, keeping personal data (contacts, SMS, lists of installed apps [not including app data]) safe. You can install apps that will make data files of your texts and installed apps that can be accessed after flashing a custom ROM to enable recovery and re installation, and for your contacts (if you store them on the phone instead of the sim card) you go to your contacts, press the menu button and select import/export, then export to SD card. If you use these apps (appbak and SMS backup and restore) and the export to SD card function on your phone, you will find that data files have been created by using them.....these data files MUST be moved to your EXTERNAL SD card BEFORE flashing your custom ROM. They will be perfectly safe there as long as you haven't played around with the storage configurations on your phone....which I don't believe is possible with a stock ROM anyway....
Good luck and happy flashing
Hope this has helped....if it has, click thanks

not so late dude
the problem is... I don't have a working backup still now!
I just flased cm9 and RemICS 1.5 rom and every time I tried to make a backup before flashing...
the first time I have the above doubt (as you can read above)
the second time I've tried to install CWM 6.0.1.0 instead 6.0.1.2 and the backup process is finish well (or it was what I belive ) then when I try to comeback to stock version an error has occurred in restore and I must re-do a flash with stock firmware because the SGW was freezed.
I don't know if there are problems with installation of CWM, the release of CWM (now I try with a CWM 5.5.0.4), with the type of backup files (n CWM6 you can choose the type of format file do you have from the backup process) but now before to flash another rom I want to have a WORKING nandroid!
thanks for your reply and your suggests too... maybe make I something wrong but I follow the tools on web and these are simple... maybe is only bad luck... I retry
Dude...if you read my thread here.......
http://forum.xda-developers.com/showthread.php?t=1846449
And specifically the replies posted by IvanKurnia, you'll find the links (and installation method) for the version of CWM that I'm using.....with success. When you make your nandroid backup, you need to make sure you have enough space for it to complete as you don't get any warning about lack of memory....the backup process will simply stop....and unless you know what to look for, you may not realise.
I'm not totally sure if flashing different versions of CWM on top of each other will cause instability or not....maybe somebody else can answer that one.....
I'd advise getting as much info as you can about EVERYTHING! before you make any more modifications to your phone.....read as many threads and ask as many questions as it takes.....most members of this community will be happy to help (though there are one or two who have a superiority complex...lol)....it's better to ask a hundred questions and get it right, than to ask none and turn your phone into an expensive paperweight.......
CM9...I don't HAVE to.....I just.....can..
first of all: I wanted to write mate not dude sorry for my bad english...
thanks keithross
I read your thread and all the replies in it...
yes the metheod for flashing the CWM is the same I knew. I prefer to flash it whit odin.
I don't think I have problems flashing other versione because I must do a replace of stock firmware before: I set the cell in the status as new... then I reflash on it the CWM.
the only thing I don't have made is to set on USB debugging ON... uhmmm maybe is this the problem?
I try now to flash, make a nandroid, try recovery by nandroid to understand if nandroid works! If not... I try to instal CWM witn the method has showed by ivankurnia
for free space I have enough space in my SD ext card (3gb ca.) and not so many app installed... and yes I use often forum and I think these are the greatest resource on the web xda for android is "the bible" I think so!
p.s. your thread has so many informations I need...
Hi Bennymax, I found ivankurnias method the easiest to use....I'd tried ODIN without success....but successfully installed CWM on the first try with the terminal emulator/busybox method.....others have successfully used this method too. I do still stand by my concerns about flashing different versions of CWM on top of each other as I've come to believe that the recovery partition is separate to the ROM partition and that changing the ROM partition has no effect on the contents of the recovery partition. I hope I'm wrong about that, and that the issues you are having with nandroid backup and restore are as you say bad luck....but I'm not convinced.....having said that, I'm not a developer, and I could be wrong. I feel that it is something that needs researching just in case the luck you've had is not bad, but good in so far as you haven't bricked your phone yet......
Anyway, good luck however you decide to proceed....

CM9...I don't HAVE to.....I just.....can..
I've found myself stuck trying to flash a ROM. I'm a newbie, this was my first attempt at something like this, I though I read enough about the process but I guess I screwed up something. I will try to be to the point.
Phone: Samsung Galaxy S3 AT&T i747
Rooted phone with Casual, installed ROM Toolbox and purchased the pro upgrade.
installed TWRP 2.5 and made a nandroid backup, the only place this backup existed was in internal storage.
used ROM toolbox to backup user apps and user data
selected cyanogenmod 10.1 RC5 from within ROM Toolbox and there was a requester for gapps and a checked the box for that also. When the DL was complete I installed the ROM queue with those two items and I checked the boxes Wipe Data & Cache and Wipe dalvic-cache.
Phone went to recovery mode (i guess) and appeared to clear the memory and load the new rom, the phone rebooted and I got the cyanogenmod boot screen but then it went to a requester saying:
Unfortunately , the process com.google.process.gapps has stopped.
When you hit ok you get:
Unfortunately, setup wizard has stopped.
this requester never goes away, just keeps popping up when you hit ok.
So I removed the battery and booted the phone in recovery mode and try to restore but the restore nandroid file in not shown. If I hit the center button in the restore window it says "updating partition details" but never returns.
Whenever you power it up normally now you end up in this gapps loop.
My searching suggested I may have tried to install the wrong version of google apps somehow. What are my options for trying to recover from this? Does my backup still exist somewhere?
If process.gapps is your only warning you can try to reflash the gapps zip from here. http://goo.im/gapps/gapps-jb-20130301-signed.zip If this does not fix your problem, you will have to head deeper into the rabbit hold
You can look for your back with a file explorer. Should be in sdcard/TWRP/BACKUPS/******** (random number). If you dont see them here, check your ext-sd in the same location. If you don't see them, they are gone. Do a Nandroid backup now just to be sure you have one. You should chose to back it up to external in TWRP. As for your FC problem, it would appear that you have not wiped fully. You will likely need to factory reset. the problem is this will remove everything. Titanium back up is a great product for situations like this. If you have used it, you can transfer your backup from the internal storage while connected to your pc. Also copy your DCIM folder as it will contain your photos. This is why you will need to do another Nandroid, because worst case scenario, you can just restore this one.
Thanks for the reply. I will try to reflash the gapps file from the external as soon I can download it, the site is having some trouble right now. I made another Nandroid of the phones current state and stored it to external. I did also have Titanium backup and had backups of the whole system with it. Unfortunately they are also only on the internal storage.
Re-installing the gapps zip file off the extSD from within TWRP did the trick. All the data and backups I created are also still there and are now backed up in several places.
Something that compounded the problem was the 64GB sd card I have for the phone. I was not able to mount it on either of my linux mint machines or an XP machine. Some oddness with the exFAT file system on it, I used a 4GB card I had laying around and it worked fine.
Thank you for the help, the phone is now running CM which is what I wanted and I learned a few things too.

I just bought a 64GB card as well. You may be having troubles mounting it due to a partition that comes factory in the SD. If this is the case, you can look at post #57 on the following page http://forum.xda-developers.com/showthread.php?t=1915385&page=6
It helped me tremendously.
Hi,
I flashed last night Temasek's CM11 4.4.2 ROM (http://forum.xda-developers.com/showthread.php?t=2596887), wiping user data, caches, etc (I was on a rooted stock 4.1.2 ROM).
Everything is working great so far, I love this ROM, I just noticed a problem that it's quite annoying: it seems that the internal user data file system (which would be the /sdcard folder in my old ROM) is all messed up and replicated. Here;s what happens:
I created a backup of the current ROM with Online Nandroid backup. If I use a file explorer from my phone (X-plore) and go to the "partition" /storage/emulated/0 I can see the backup created in /storage/emulated/0/clockworkmod/backup/.
However, if I connect the phone to my PC and browse the contents, the partition that I see isn't that same partition, it's an older one with older files (for example it has a clockworkmod folder but the backup isn't there, and some folders are different). What;s worse is that I can't find this "old" partition when browsing my phone with X-plore. These are the palces where I've looked at:
- /storage/emulated/0 (shows the partition where the backup I just created went, I can see the backup there)
- With root privileges:
- /data/media (shows an older second partition with different folders)
- /data/media/0 (shows the "right" partition, where the backup is)
- /sdcard (again, shows the "right" partition)
- /storage/sdcard0 (same here, shows the "right" one)
So to sum up, it looks like I see at least 3 diffent partitions:
1. From my PC, I see an older one that I can't see from X-plore (I tried Cyanogenmod file explorer too)
2. From my phone, I see the one that has the backup I just created
3. From my phone too, I see a second old partition (different from the one I see from my PC)
So what I would like to know is:
1. How can I transfer the backup to my PC if I can't see the partition that holds it from there?
2. Is it safe to just delete all those folders in both old partitions? I'm sure they're taking space unnecessarily
Any help would be much appreciated!
After flashing any CM/AOSP Rom. They actually create a different folder set up. That's because of the ability of different users...
You need to apply the restore SD card after downgrade.

Hey! So it seems that did it!!! Now I can see ALL the contents in the /sdcard partition (X-plore shows it as /storage/emulated/0)
So my question is (I'm still pretty noob at all this): all the files/folders shown there shouldn't be critical for the OS to work, right? They should all be stuff saved by apps, that if they get deleted the worst thing that will happen is that those apps will lose that info, right? I ask because I can recognize most of them, but not all of them, so I'm not sure, and I would like to remove as much stuff as possible.
One file that makes me doubt specially is /sdcard/clockworkmod/download/download2.clokworkmod.com/recoveries/recovery-clockwork-touch-6.0.4.3-t0lteatt.img. Is that the actual CWM recovery that I have in my phone? Or just the installation image that can be removed?
Thank you very much for your help!
I ended up deleting everything from the sdcard partition and restoring the stuff that mattered to me, and everything seems fine now. The only weird thing is that when I create a backup with Online Nandroid backup (which gets stored in /sdcard/clockworkmod/backups), I can't see it when connecting my phone to my PC. I can see everything else in the sdcard except the backup. I've tried unplugging and plugin again the phone, rebooting it, rebooting my PC... but nothing. However, if I zip the backup folder with X-plore, leaving the zip file in the same folder as the backup folder, my PC can see it...
Weird thing but oh well!
Hi together,
just as a disclaimer, I don't really have knowledge in this field (custom roms etc), but I'm willing to learn and understand what is going on.
I have the Moto G5 as my daily phone with the unofficial lineage 17 from the xda-forum. It's not rooted. Now i saw that the g5 got official support for LOS18, so I wanted to upgrade. However, I had some important files on my phone, so I wanted to do a backup (with twrp), which i did on a different sd-card than the one I was using as storage. Or so i thought. The upgrade itself wasn't really a problem, at first i forgot to wipe the phone, but i realized right after the installation, wiped it accordingly to the instructions and did the installation again. The phone booted without a problem and everything seemed fine. I encrypted the phone accidently, i thought it was the lockscreen pin. But it wouldnt recognize the sd i used as storage on the previous version. Because i had pictures, music etc on the card, i wanted to restore my backup to use the phone as before. Well... to my surprise, on the sd i used to back up i couldn't find it, but strangely there were now two versions of a backup i made some months ago, only different in the timestamp (not the date) in their filename. I didn' know if one of them was the one i made, or if i had made two backups back in the days. I was confused, but i chose on of them at random and restored it. It seemed to have worked, it booted to the familiar lockscreen i set up a while ago. But then: it wouldnt accept the pin, even though i knew it was the right one - at least for the system i have used the same morning. I had to delete the lockpin.db (or how it was called) via twrp to acces the phone again. The former uncompatible storage sd now got recognized and worked, the phone showed all the apps i had before, i was still logged in in all of them etc. But: i made a photo, wanted to look at it in my gallery app, and i briefly saw my albums - then they vanished and only the photo i had taken was there. So now all the pictures, music are gone from the sd. Some funky things are different, the swipe directions for the "recent apps" and "back" buttons on the fingerprint sensor are switched and i cannot find the menu to change them. That's the story.
Here are my questions:
The backup i made - why wasn't it called with the proper date and time? Or have i deleted it somehow due to my wiping mistake? but it was on the sd... ?
I now assume i restored the old backup with a different lockscreen pin, and thats why the pin i thought was correct didn't work. But some apps which i hadn't installed at the time i made the backup where there and with all the recent data. Doesn't that mean the sd has some kind of image of the system or rather the apps themselves stored? but why are the pictures and the music gone? Is there any chancce to get it back? Can I upgrade to LOS18 and use the same sd as storage without the need to format it?
I'd like to learn what the mechanisms behind all these happenings are and would be glad if someone could explain it! Thanks in advance!
Twrp backups do no backup personal files - This includes music pictures and documents. These must be backuped up yourself to a pc, external device or the cloud.
TWRP backups do backup the following for example
System - your current rom
Data - apps and their data of your current rom, phone settings
Boot - Kernel
Never restore data on a different rom. The data contains apps and settings for your current rom and restoring this on a different rom will likely lead to a bootloop or an unstable device. This is why you had issues with passwords.
In regards to personal files - if you have formatted data of an encrypted device then it removes encryption and thus formats internal storage. Anything on this will be lost.
If you are changing roms you need to format data and then install everything again via the playstore (or manually via apk)
You can use 3rd party apps that backup apps and data but I advise against this as what it restore may be unstable on a different OS
As with the twrp date I assume twrp assigns the correct date. The file would be lost if you backup up to internal storage and your formatted data. I don't know what happened to it if you backed up to an external device.
