Using CWM you can create backups and restore them back onto your devices. Why is it that we flash the zips rather than just flash other peoples backups? And whats the weakness in doing this? Just curious...

I used a mod ROM but I made a backup before doing that. The problem is that I use now CWM recovery (6.0.1.2) and I cannot restore the stock data. I get "Error while flashing boot image". I do not know what I am doing wrong
I go to restore from internal sdcard --> and I choose the restored backup
I have wiped all the data/cache & dalvik cash available. But still nothing. Does anyone know?
Did you use a different version of CWM recovery when you took the backup? If so it might have a different version of nandroid backup in it and be using a different backup format. If the CWM recovery is different, can't you put the original CWM recovery back on so the backup will restore with it?
Unfortunately I do not remember which recovery version it had but I am almost certain that it was the same version

An easy way to tell is to think about if you ever installed a new recovery. ROMs don't do that for you. ROM Manager has the ability to update your recovery image if you tell it to do so.
Your error is telling you that the recovery you have installed doesn't know how to handle the backed up boot.img. You could removed the boot.img from the backup and try restoring it again. Google it, if you don't know how to do that.
Does the MD5 check pass?
I just installed 4EXT Recovery, and it was able to restore my recent CWM recovery backups where CWM could not (>10,000 files bug). It appears that it doesn't support your device yet, but you never know.
Failing that, perhaps look at other alternatives. Maybe see if TWRP can restore CWM recovery backups, and if it supports your device.
Good luck.
I have just rooted my n5, and for now I want to stay stock.
I want to backup my efs partition, just in case. Is it possible to do so using the stock recovery, or make a full nandroid?
You will need custom recovery and then can do either a full backup or just the EFS. I know for certain that TWRP gives you the options.

I know I can do it with TWRP but is dit possible without custom recovery ?
Hello
All XDA members
I have a problem that made me raise a question an that is an we know the name of a rom from a nanriod backup either on PC or on Andriod.??
Ideally PC would be good !!
Thanks
Most ( not all) recovery apps let you name the file. Are you asking how to find the file? If so, it likely is in a folder named backups. You can move the file to your pc and keep it there if you are out of storage space.

Sorry if I wasn't clear please consider the following situation :
I have around 12 backups of different roms and I dont want to restore each n every backup for sake of simple file or simple thing. So any tool which can read the name of Rom? Probably the buildprop or about phone info will help

Well, if you gave a single boot system, your recovery should "see" all of those files. If so, you can usb them or copy to a sd card and move them. Just move them back when you need to.

Can someone explain nandroid backup to me? Does it mean I can make a backup my current rom and save it? Sorry for the dumb question.
Yep

Simply,it is a backup of your OS and settings. It is extremely valuable if you flash a new ROM that doesn't/won't function. Then, you can use your recovery to, well, recover your previous WORKING OS.
When/if you begin to flash new ROMs (and other tools that may corrupt your OS) you should always.first.backup.your.files.
Can I assume I would need to wipe data/factory reset, etc. before I restore the backup?

So, that depends on what your starting config is, what you upgraded to.
For instance, if you are stock and flash a ROM using the stock recovery, then likely yes. You should and you would use the stock bootloader to wipe with.
If you have loaded a new recovery (TWRP, CWM) then read(!) the instructions on the developers page. My example is that on my tablet, once I upgraded to TWRP, I SHOULD NOT use the factory wipe option as that would wipe both TWRP and the backup files. That would cause lots of problems so, don't assume.
Typically, you do need to data/reset/wipe prior to flashing a new or recovering to an old ROM, just be careful what/how you do it.
I have a CWM recovery installed and installed custom Rome before. I have always redid everything again. So a backup would save me a lot of time.

Then, unless the ROM developer states otherwise, you should make backups, wipe data, install ROMs and recover your device using the Nandroid backup.
You likely shouldn't use the "factory" wipe data as that would cause issues.

How can you update a ROM (cyanogen in this example) on an encrypted device, using CWM? I know that OTA is not possible when it's encrypted. But can you even create nandroid backups of encrypted devices, and restore these encrypted backups after flashing the updated ROM version? I'm totally lost how to update the ROM without losing all my data.
I'm not sure cwm supports encrypted devices. Use twrp. And you can create nandroids of encrypted devices using twrp.

The problem is, i can't use TWRP because a part of my screen doesn't respond. Is there no way to create and restore nandroid backups of encrypted data on CWM?

Just make a nandroid backup of your current ROM before you flash the kernel, if you need to go back to stock just restore the nandroid and you'll be back to what you had before you flashed. No need to complicate things with trying to backup just your stock kernel, a normal nandroid backup will do what you're looking for.
