Can I just restore the twrp generated nandroid on a replacement nexus 6?
not recommended, but you can try; just be prepared to restore it from scratch if it locks up..

Do NOT do this. A nandroid contains files that are device specific. You could end up needing a new replacement.
The replacment is another nexus 6 and I'm talking about the backup that twrp makes.

I know what you are talking about. Apparently you do not know just what the nandroid does or what its purpose is. A nandroid is a back up off the partitions on your device and some contain files made per device.
Just save yourself the head ache and set it up fresh. Doesnt take too long.
K thank you for the info
ok, all you people saying no, ive done this a few times with absolutely no issues after. BUT, it has to be done right, or you will have issues. just be sure that you create a nandroid on the new n6 first. then delete that new nandroid and stick the old nandroid in that same exact spot, within that folder. if the nandroid is from a phone thats not a n6, then make sure that only data is backed up and restored, nothing else.

Then you are running a very big risk of messing your imei and baseband up permanently. Nandroid backups include all partitions. They should only be restored on the device it was pulled from. Too many people trying to take the easy way out and being lazy. This leads to people doing warranty returns which to be honest unless you always remained stock and never modded then you should never use.
I'd done this to my one plus one but restore only boot , system and data partitions none other , no problem.. But thus is Nexus 6 , I don't want to take risk.

wrong.. nandroid backup have whatever partition you included in the backup. DO NOT BACKUP YOUR IMEI!

Before telling someone they are wrong. Let alone me. You have to take into account how normal people will do it. Now just from your statement people will be expecting an IMEI partition. When they dont see one they will do a full nandroid and then guess what happens? You have to remember that people understanding what they are doing is not the people that need help with something like this. No one that has any real clue would restore a nandroid from one device to another. Hell most dont even bother with nandroids anymore. They are more noob tools then anything else.

From what I understand the EFS contains some device specific information? Here is a blurb I read:
"But What is EFS?
Now that I have your attention about EFS, you might be curious to know what is EFS? EFS is a System Directory, that contains some important information about IMEI, Wireless MAC Address, baseband version, Product Code, System ID and NV Data. Usually your EFS data remain safe no matter what happens, but its corruption occurs when you try to install any Custom ROM and Got this error."
So if we share a TWRP back up that includes EFS and someone else restores that EFS, what will be the out come? Possible wrong IMEI, mac address, no connection?
It's a bad as crossing the streams- total protonic reversal. Try to imagine all life as we know it stopping instantaneously and every molecule in your body exploding at the speed of light.
It would be bad.

I figured so. I thought I would put the question out there for more experienced people to verify. I just noticed TWRP allows me to back up my EFS stuff, and I seen someone share theirs in a twrp backup for others to flash. Looked like bad news.

Yeah I honestly have no idea exactly what would happen, I just know that if your EFS gets lost/corrupted you are pretty screwed, unless you have a backup. I'd imagine that flashing someone else's EFS wouldn't be the smartest thing to do.

Unless I'm mistaken, only Samsung devices have the EFS issue. Here's a thread on the Moto X forum acc to which the X doesn't have the EFS issue (LINK). Most likely this device doesn't either. So using another's TWRP backup wouldn't be a problem.
That would be cool if it didn't. I seen our twrp version makes a backup of a EFS partition of sorts. Your link seems to refer to the 1st gen moto x? Hopefully your right, who wants to worry about EFS corruption.
Hoping I'm not totally screwed here, but here goes. I'm swapping from one Nexus 6 to another. On stock 5.0.1 (still), rooted, and unencrypted. I made my Titanium Backups (always as a precaution) then booted to TWRP and made a nandroid backup. I was too tired to command line myself so I decided to use the Skipsoft Toolkit to pull my data. I got curious about a full backup option on there so I tried it out. First thing it did was boot an unsecured boot.img. Phone then boots back up and begins the encryption process. I knew I didn't want encryption, so I powered off mid-process. (Kicking myself for that now...) Now when I boot back up, I get the "Encryption Unsuccessful" message telling me that my data is unusable and that I must do a phone reset.
I can still get to the bootloader and boot into TWRP, but it can't see any of the data on the device--including the TWRP backup I made earlier today. Seeing as I didn't get any of my backups off before this happened, I need that TWRP or I will lose everything since my last backup on 11/6. Is there ANY way to still pull data from a partial but failed encryption? Please help!

You most likely corrupted all the data on the device.
Not sure why you thought powering off during encryption would stop it and not cause corruption.
Also dont even think about restoring a nandroid on a new device.

Because I wasn't thinking... I know--stupid. Is there no shot at recovering anything?
I'm switching from one Nexus 6 to another. Can I not restore a nandroid to an identical device?

No, no you can not. A nandroid has device spicific files in it like GPS and IMEI info. Restoring it is just asking for trouble. Only restore USER apps and data everything else is off limits.
How did you fix the issue?

So what specifically is in /system or /data that would be so dangerous?
Have you ever actually done this, or are you just saying stuff you have read but don't fully understand?
If you backed up every single partition its a bad idea to restore to another phone... But simple backups are fine to restore cross device if you aren't including efs

You do know who your talking to right? I don't read things. I do them. Been doing this for over 10 years now. So just maybe you might want to know who you are talking to first.

Nope, no idea who you are.
All I know is how many times I have seen twrp backups restored on a phone it wasn't taken on with out issue?
Maybe you should actual read things and you wouldn't have an issue with it either?
Or... Care to actually explain the danger rather then just puffing your chest out because you have played with android smart phones for ten years (apparently since before it was released?)
lol!
ok, both @zelendel and @scryan are right..
its highly not recommended to restore a nandroid onto a different phone if it contains system apps. that said, theres also a chance that it would be fine as well. its just that the system apps could not be supported(or could be) by the 2nd device. but even if they arent supported, it wont really harm your device, as you can fix whatever issues by just switching out the apps that are causing issues(then reboot).

Well let's start out with the fact that when system apps are loaded the data loaded to is set to one device. By restoring that to another device messes it up and causes all types of issues with the app and system.
Also as stated above not all apps are compatible across devices. Could lead you to an endless bootloop.
See you have me twisted. I don't have to read about it as I do it everyday. As each device is different there is no telling that one thing will work for one but not the other.
As for doing this before android was released? Yes. Who do you think got leaks to run on wm devices before the first nexus was released? Xda and the legendary HD2.
I was modding devices before the first smartphone was even released. Then I became a moderator here. Which is requires a whole lot of learning. Like reading the source and knowing what does what.
Now you are more then welcome to flash someone else's backup, that is up to you but I will tell you that no one that knows what they are doing will do that.

the Dream(G1) was Googles android developer phone before the Nexus. while a lot of people did use and mod the HD2, the G1/Dream was getting most of the developer support.

Just wanted to chime in here and say, I agree 1000% that I would never restore a backup from one phone to another, unless I knew for a fact I could "rescue" the phone if it locked up/got fried/ruined from the restore..
And, I have been playing with cell phones since November 1983, the first day cell service became widely available in Chicagoland, and I have been modding/tweaking/hacking them pretty much since then, so I too have "extensive" experience about what may or may not work when doing something like this..
To each his own, but I would never do this..
Me and my wife use the exact same model phone and both are rooted. Hers has had a few issues that have made it unusable at times. Mine works as it should. Question is, can I use my backup on her phone to restore a 'good known working' system? and then just modify it for her stuff. I'm assuming she would keep her phone number and all that (I get a little foggy when it comes to all imei/sim stuff).
Any help would be greatly appreciated.
Thanks in advance.
yes you can, but only do NOT restore EFS and is all good.
Make a nandroid backup first.

Is there any method that I can back up the device completely so that I can venture into other roms including imei in case of losing
TWRP does a full backup. It does NOT backup your user files though on the SD Card. Just make sure that after you make the full backup that you go to the SD Card and copy off the TWRP Folder to a PC or if you have a Duo Thumb drive like me, plug it in and set it as the save location when you are backing up with TWRP.

They lose their imei cuz they don't know what they are doing and follow a lot of bad advice given by others that don't know what they are doing - classic case of blind leading the blind. I've run almost every rom, restored stock a couple times, never lost imei.

Hey everyone thanks to @BIOKNOX who recently helped me get my Note 9 working again, I want to make a complete software backup. A complete IMAGE of the current software so just in case something goes wrong, I could have somewhere to come back to. So I need help with that. I use twrp will that work? Is their a better software? Will Twrp work the way i want it to? Thank you in advance

Since you're using TWRP then that's the best. Make a backup of all partitions. If there is a problem while restoring try to restore one by one, maybe some cannot be restored, can't say nothing here. But a nandroid TWRP backup is the way to go, yes.

Hey, I backed up the file in steps, cause I did not had a big SD card at hand. The problem I am facing is I cannot backup system image. How can I backup that file? Is it important? Btw all back ups are done using twrp and I just realised that I could have just backed everything up in the phone storage and then copied it all as one file on to my laptop.

I haven't had any experience with TWRP or such things on phones newer than the Galaxy S5. I don't see a point to root or tinker with my Note 9 as it's perfect stock so can't really test if i can backup the system image myself. All things are important in a backup, is it grayed out or something? I'd always do a full 1 backup though, not in parts. Seems easier to restore later.
