I wouldn't think so, but I'm really clueless about what's going on...
I have Cyanogen 3.9.8
I want 4.0.2
When I use the CM Updater, I get the dreaded acore Force Close.
So I try the manual approach, putting the 4.0.2 zip file on my SD card's root, then I reboot into recovery, and I perform a Nandroid backup (I run Linux on my computer, and don't use ADB).
Then I do a wipe, before I install the 4.0.2 zip.
Finally, I do I Nandroid restore.
Rebooting takes a long time, which tells me something has been done in the ROM department.
But when I have it up and running, everything seems just as they were before the operation, and when I start CM Updater it says "Running version: CyanogenMod-3.9.8"
I tried again, this time I booted the phone before I did the Nandroid restore, was met with the "factory fresh" Google account login screen (so it looked wiped to me...), then did a reboot to recovery and a Nandroid restore, reboot, checked CM Updater: "Running version: CyanogenMod-3.9.8".
Maybe I need to tweak my ROM updating routines..?
I have 3 partion SD card, so apps2sd is running.
Any help is highly appreciated.
Thanks,
Christopher
I'm kinda confused here, it's Monday morning. Since your trying to upgrade why do you keep doing a nandroid restore? You only want to restore nandroid if you want to go back to that previous point when you made the restore point. If you are just upgrading, just upgrade without restoring nandroid.
do exactly what you did without doing the nandroid restore at the end
Nandroid Restore is pretty simple.
Say you have ROM1 installed and there is an experimental ROM2beta out. So you want to try it.
Do a nandroid backup and it saves it to your sdcard.
The files that are saved are:
recovery.img
data.img
system.img
cache.img
misc.img
boot.img
This is almost every part of your phone except the spl and radio.
When you do a ROM upgrade MOST of the time it only updates the system and boot (some ROMs like Hero wipe/update the system, data, cache and boot.) But if your going from Cyan1 to Cyan2 then the only things being changed are system.img and boot.img. Unless you wipe, everything else should remain the same.
With all that said... you flash from ROM1 to ROM2beta and then do a restore from the ROM1 backup. So what does that mean for your phone? Is it possible to have ROM2beta ROM with the ROM1 system.img and boot.img? No. Since system.img is restoring the key elements for the ROM1 over your newly flashed ROM2beta. Bottom line. You'd be right back to where you started.

Which explains what I am experiencing.
Thanks, 36!
That means I have misunderstood what Nandroid does.
I thought it would just take a backup of "user changed" files, like application data, configurations, call logs, that sort of things - like MyBackup Pro, more or less.
Guess I will get back to using MyBackup Pro before I upgrade my ROM.
Thanks, this really clarified things - I'm sorry I had to post such a n00b question, but I haven't found any other Nandroid postings telling me in such details what Nandroid backs up (and restores) - but then again I probably haven't looked hard enough! ;-)

Seems I had the same misconception and it seems that Nandroid is not nearly as useful as I had been led to believe by all the posts harping on about it. What I want is a backup of all my user data which I can restore to the updated ROM. Luckily I suspected Nandroid wasn't going to do this and used MyBackup Pro too

nandroid can do this you just have to do a backup flash youre rom then push youre data.img
I understand you push the data.img but.....
how...
please
Perform a nandroid backup
Locate the backup on your sdcard under the foler "Nandroid"
Navigate to the last folder (this should be your latest)
Copy all or at least the folder that you want to push back (in this case just data.img to a directory say c:\nandroidbackup)
Open the cmd prompt and make sure that you have your fastboot.exe file in your pc's system32 directory.
If your phone is already on type "adb shell reboot recovery" in the cmd prompt to get to the bootloader and ready for FASTBOOT and then type "exit" to quit the adb shell.
If not then power on your phone while holding the camera button to get to the bootloader and then press the back button on your handset to get to FASTBOOT mode.
On your cmd prompt type "cd" along with the location of the data.img file (example cd c:\nandroidbackup) to move the command prompt to the backup location.
On the cmd prompt type fastboot flash userdata data.img and hit enter.
You should see "sending" followed by "writing" once complete type fastboot reboot and hit enter.
That should do it.
Now mind you that pushing your data across different builds may not work. If you are trying to restore your data on Hero that was previously saved from Cupcake then you're wasting your time. And vice versa. Always store a backup or two on your pc for quick and easy access in case something doesn't work.
In the event that it does not work simply wipe and follow the above directions to restore.
fastboot flash system system.img
fastboot flash userdata data.img
fastboot flash boot boot.img
Thanks great thanks mate!!
On the cmd prompt type fastboot flash userdata data.img and hit enter.

This step fails for me during the "verifying signature" phase. I believe this is todo with my spl.
Is it possible to use adb to do this? or will the spl still prevent it?
This makes a cwm compatible backup from terminal. No need to go to recovery.
The script is from ameer1234567890 , I just made a working package for the GT-N51..
Your device needs to be rooted.
It makes a backup of your system by typing in terminal su(enter) onandroid(enter)
This will backup: to externalSD if present if not on the internal sd in the folder clockwork
Boot.img
recovery.img
system
data
cache
efs
modem (if present)
You can select only one partion with typing onandroid -ah
This pops up a menu of partitions.
pick the efs for example.
onandroid -a e (enter)
onandroid -h = is the help menu
Full details can be found here
Flash the attachment with cwm.
Note: I tested it on my tablet and it backup everything, it takes it time , 16 minutes but it is correct and finally a easy way to get the efs.
It is possible that the backup is not visible , just reboot and then you will find it in your clockwork folder.
If you done installing the flashable zip you can install the following app from the market, this will replace the terminal and makes it even easier for you.
But you need the attached zip installed first, if not the app will not work correctly.
Maybe I can get this integrated into CWM, the efs and modem part. Thanks for this.
I have a very decent working ROM at the moment (4.4.4 rooted xposed gravitybox etc.) and I'm not sure I can live with Lollipop without al those tweaks. So before upgrading to Lollipop (whenever that may be), I want to make a decent backup of my current ROM.
Normally I would do this with TWRP, but the backup doesn't seem to work at the moment. And there doesn't seem to be a properly working version of TWRP.
So how do I make a proper backup of my ROM?
Adb?
A confirmed working version of TWRP?
CWM?
Another?

You can use standard tools installed on the phone to dump your partitions. See here for a rundown. I'd recommend backing up /boot, /recovery, /system, /pds, /modem and /fsg.
Ah yes, that's what I was looking for. Thanks
When I restore the mentioned items, will I get back my old installation? Or should I backup more? i.e. userdata for example?
And how to restore all these items? (I know to flash the boot, recovery and system.img via adb).
Yeah, you'd need to backup the data partition too, if you want to keep settings and user data. Remember, dd produces a 1:1 copy of the partition... I prefer to backup personal data selectively. The quick way to do it is by using a backup app: Most use Titanium Backup, but I find Chainfire's Helium does the job well, too. The other way is to use the built-in 'backup' command directly to select a range of files to save (i.e. 'adb backup')...
The partition images can be restored from adb using the reverse version of the command you used to make to the backup, i.e. use dd but with the 'if' and 'of' parameters switched:
Code:
dd if=/path/to/source.img of=/path/to/block/device
Be careful though; if you write the wrong image to the wrong partition, you can damage -- or even hose -- your software environment.
In the case of most partitions, restoring images should be done whilst booted into recovery for safety reasons, rather than overwriting a filesystem whilst it is mounted and in use. If you have the stock recovery installed, you can temporarily boot into TWRP or CWM recovery from a recovery image stored on your computer (i.e. 'adb boot /path/to/recovery.img') and then enable adb from within the custom recovery environment. Then you just use 'adb shell', followed by the 'su' command to switch to the root user account.
For the same reason, you should write the recovery partition backup back to disk from adb within the normal android environment. Again, you must do this after switching to the root user account by issuing the 'su' comand.
Alternatively, you should be able to write all the images from fastboot mode (i.e. 'adb reboot lootloader'). For example:
Code:
adb fastboot flash recovery recovery.img
AFAIK, fastboot will accept standard images created with dd, but I have never tried it on a Moto G, so YMMV... Maybe someone else would care to comment on this?
I made an ADB backup via TWRP of each partition (boot, system, data, cache) individually direct to my PC prior to flashing a new ROM. After flashing the new ROM, I realized I forgot to backup texts and wifi netwroks via Titanium Backup. I tried to restore each partition so I could go back and copy the texts and wifi networks but it didn't work. TWRP reported no OS installed and it didn't boot either. I did update the bootloader after I created the backup and am not sure if that's why it's failing.
Is there a way to extract the texts and wifi networks from the backed up file(s)? Do I need to flash a previous bootloader to get the backup to work?
Thanks

I would say no but I'm drunk at the moment:laugh:. WiFi and text should be a part of data part of the backup. I see that you backup data so it should be there but I don't think you can do it the way you tried. Let's see what smarter people have to say.

Nope, I've never heard of a way to extract anything from a TWRP backup file without restoring it. I've never had to flash a different bootloader to get a TWRP restore to work, even after the bootloader was upgraded by the new ROM I installed. I assume that the bootloader is restored when restoring the TWRP backup. How did you restore the backup? Did you restore the entire backup (all of the partitions) at the same time or try to do them one at a time? I've only had luck with restoring the entire backup at the same time.

The first backup I made which had all the partitions in one file didn't seem to work properly as it did not copy the file locally to the PC. I tried it again but created a separate file for each partition which seemed to work so I have 4 files in total. I restored the files in this order: boot, system, data, cache. When it finished I got a message when exiting TWRP that there was no OS installed. I rebooted anyway and it failed.
Is there any way of restoring it to an emulator running on the PC?

It's likely too late for this now but I've backed up to and restored from a single file on my PC by following this guide quite a few times in the past without any issue. My thoughts are if the files won't restore to your phone they probably won't restore to an emulator either but I honestly have no experience with emulators.
Hi, I recently made an adb backup through twrp and now want to open the file with droid explorer. It asks for a password, when entering the one I had on the phone it doesn't open, I even tried restoring it through twrp -> didn't work, with booted phone it asked too for a password -> also didn't work. Do you guys know if twrp has a password which it sets automatically?

In the recovery terminal with the restored backup, delete "/data/system/locksettings.db". That should allow you to boot to system without a password. There is a benefit to removing PIN/pattern locks before making backups.
As there is no decryptable TWRP, it isn't as easy as before to bakcup the EFS partition. But doing it via Terminal isn't too difficult. I didn't find a good tutorial that isn't burried somewhere on the internet. And none for the 7T Pro (though the commands and partitions are the same on older OnePlus devices.
If you already know how to boot TWRP or you already have it, go to the second instructions list and skip the first one.
I am not responsible if anything goes wrong. You do this at your own risk!
Requirements:
- An unlocked bootloader
- Working adb and fastboot (e.g. Google's Platform Tools)
- Download a bootable TWRP
Instructions to boot TWRP:
- Connect your device via USB
- Go to Settings > Developer Settings > Enable Advanced Reboot Menu
- Hold down the power button and select "Bootloader"
- In the bootloader use (It won't modify anything, you simply boot into TWRP once and after a reboot it's "gone".)
Code:
fastboot boot NameOfTWRPImage.img
Instructions to backup EFS:
If TWRP has booted, type the following into your computers' terminal one after the other:
Code:
adb shell
dd if=/dev/block/sdf2 of=/tmp/modemst1.bin bs=2048
dd if=/dev/block/sdf3 of=/tmp/modemst2.bin bs=2048
exit
adb pull /tmp/modemst1.bin modemst1.bin
adb pull /tmp/modemst2.bin modemst2.bin
This will copy modemst files to the temporary folder on the phone (which can be accessed though the data is lost after a reboot) and "adb pull" copies them from the device to the user's profile folder on Windows or Mac. You have successfully backed up the EFS partition!
Please note that this could be performed with root permissions on a booted device. Though I always prefer backing up files with a non-booted system. Also this guide will work if you're not rooted.
Is it possible to backup all system and data so we dont have to setup everything in the device after a factory reset? I mean, that backup we all were used to in TWRP.
Best regards

Unfortunately not. Backing up EFS doesn't require decryption as it's not stored on /data. Everything on /data can't be backed up afaik.
Also /vendor and /system can't be mounted as of now making a Nandroid backup impossible.

That is a shame. At least titanium backup still working great.

Macusercom, thank you for the guide!
Now how do we restore them? With the opposite dd command?
Or we can just flash them directly via fastboot?
Also, what is the full list of partitions which contain data unique to this specific device?
I mean all these EFS, persist, IMEI, screen/touch calibration data, all sensors factory calibration data, fingerprints, etc.
Is it only EFS + persist or there are more of them?
