Hi guys, little issue here with nandroid backups. I've been using the 6p since it's release and have tried about 5 different Roms. I like switching between them monthly or weekly, but every time I attempt a nandroid restore, I get a boot loop. Every time. I'm using twrp recovery, and when I go into backup, I just leave the default ones chosen, but I've even tried choosing all of them. The boot loop goes on for over 10 minutes before I power it down. I've tried wiping the phone, minus storage, I've tried restoring without wiping and both fail.
Can anyone here tell me what I might be doing wrong? I've looked around for guides but they all seem to work without issue for everyone.
Edit: maybe if someone can write me a simple guide on how to do a nandroid or link me to one in case I missed a step, although it seems pretty straight forward, I'd appreciate it

All you need for a backup is system, data, and boot if that's what you're doing it might be you need to flash the vendor
I'm having this issue as well. Maybe we can work together to narrow it down. This happens every time and the only reason can currently think of is that I may need to remove the fingerprint and pin security before the backup. My question to you is, have you tried disabling lockscreen security before backing up?

You're most likely selecting the wrong options when creating the backup. There's a section dedicated to nandroid backups in my guide here:
http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928
This helped a lot, thank you.

Simple question, one i didn't find a quick simple answer too.
I know the main differences between one-click root and unlocking the bootloader, and the biggest for me was the warranty. I used one-click root so just in case, I could revert back. Now my warranty is just about up, and I figure why not? My biggest question is, will it provide any benefits?
For some reason I have never been able to install themes (either update.zip files or through metamorph), I just go into an infinite boot loop. I was hoping this was the only issue. But I don't know enough to know the answer
Benefits are safer radio flashing, and if you ever **** the phone up so bad you can't boot into anything other than the bootloader, you can fastboot flash everything required to get going again.

One more little question; Should i reflash CM7 (im running the nightlies currently) when its done? I read that it will wipe all data (already got everything backed up ready to go) but I was just wondering if I would need to reflash anything right now, like CM7 or the recovery?
Take NANDroid, unlock, restore NANDroid, continue as if nothing happened.

Tons of awesomesauce I guess thats what I will go ahead and do! Thank you so very much for the quick help!
EDIT: Done, restoring the NANDroid backup now I hesitated a little bit when hitting that button though, a year of me holding back doing it because of the warranty was still making my trigger finger nervous
... And back in my rom, everything normal once again And again thanks for the quick help.
Well not so normal; I have lost my setup accounts, and everytime I try restoring a NANDroid the accounts are still gone, and there isn't an option to add in a google account and none of the google apps work. No force closes just closes the second you try to open it.
I have tried reflashing both the rom and gapps, still no good.
Am i going to need to wipe?
Certainly shouldn't do, I unlocked my bootloader in the same way and everything continued as normal.
Bit odd that you can't add your account back though, the option should be there under accounts & sync.
It sounds like what happens when you try and use CM without adding GApps
That's what I thought too. So I tried flashing gapps, nothing.
Went ahead and did a full wipe. Quite amazed so far what all android is restoring for me. Nearly all back

TWRP 2.5.0.0 reboots my device while performing a restore. It usually happens during the DATA phase. I've tried two different restores and the same thing happens. Thanks
If you need more detail, i'll do my best to provide.

I've actually been getting random freezes and reboots in TWRP myself, in the last 2 weeks or so, since I've gone flash-crazy. Have you been flashing a lot?

I wouldn't say flash-crazy, but i've tried two different roms in the past two days. It's not really freezing either. It will just start to restore, make it half way through, and reboot. My rom will be restored but none of my data.

Yep, seems to be happening a lot. One suggestion was to revert to 2.4 or even 2.3.3.0. I tried that, and thought the problem was solved, but then it happened again, so I figured what the hell, I'll go back to 2.5.
You're right, it always happens during the data restore, but so far the second attempt at restoring always succeeds, so it's more annoying than anything. I can't recall it ever happening on my phone, though, so I wonder if it's a device issue. Also my phone is running JB 4.1.2 and my N10 is on 4.2.2.

So yesterday I went to flash a new ROM and TWRP froze immediately after doing a Factory Reset Wipe. Nexus kept bootlooping and then getting stuck on the TEAMWIN screen. Was able to get into the bootloader and flash the stock image and unroot through the Nexus Toolkit. I lost all my data though. So my question is, if you can get to bootloader mode and the toolkit recognizes it in bootloader mode, can you recover data without having to do what I did and wipe the device? For future reference sake. God I need to get better about backing up my data on my PC.
Anyone found the solution to this? I am not able to restore my data ( During the resotre in TWRP it goes blackscreen and then just reboots. I've triel like 10 times already..

I had the same issue. Its most likely a corrupt backup and can't be solved. But if you've successfully restored that backup before try reflashing the recovery. Just a tip that somebody else gave me. Use philz cwm touch recovery. It has no issues and more reliable then other recoveries.

Yes, i'm thinking the same. Maybe it also because the backup was huge (maybe like 4 gb).
But I am not really sure if it is corrupted because the system restores fine and data do not, but it fails in different places, i.e. it may reboot in 30 seconds and may reboot in 2 minutes...
I have 2 backups that I have tried to restore while using twrp 3.0. No h seem like they restore but when the phone gets to the screen where it would eventually say Android after the animation never goes away and the phone doesn't boot all the way up. Has anyone else had this problem or know a solution. When I did my back ups I backed up everything available including vendor and vendor.img. I just continue to get a bootloop and phone doesn't boot. Thank u to anyone who may help
This happened to me as well even before trwp 3.0. It worked for me once I restored only boot, system, and data.

Thanks. I think I tried this how you've said but I'll try again later as I need to make sure my phone is working for now.
Since day 1 I've always backed up boot, system and data. Not sure why anyone would ever back up anything else. Takes up too much space and is unnecessary. I've never had one issue. On all past devices (all Nexus) I've always backed up boot, data and system. New twrp is great! Now we can flash vendor images!! ?

Hi guys.
i'm new here and greatly appreciate the knowledge here. I recently installed purenexus on my 6p. first time installing a custom rom. worked beautifully until i decided to try out the lockscreen scramble pin feature. Now when I try to unlock my phone it doesn't recognize my PIN. i've tried many times and something undoubtedly went wrong. is this a known issue with scrambling your pin?
So what should i do? A quick google search suggested I restore a backup. Is this the recommended method? I did a factory back up, i think. i did the back up after the factory reset but before flashing purenexus. i used the default twrp back up settings, which i believe did not include the vendor file.
i'm a complete novice when it comes to this sort of thing so if someone can give me a step-by-step explanation for me to unscrew myself here i'd greatly appreciate it.
thanks.

I am. 100% certain.
it really seems as if my password was for some reason changed. before someone asks i am definitely using the correct pin. its the same PIN i've been using for years.
how do i regain control of my phone?

Yes, if you clean flash the ROM you'll be able to get back into it. Had you restored a nandroid backup recently by any chance?

thanks a lot for clarifying that. i guess i have no other option.
has this been known to happen? scrambling PIN causing the pin to change.
I dont have a recent nandroid backup because my purenexus flash is only days old. is there a way to automate nandroid backups? is it wiser to keep the backups on the phone?

I've never seen this happen before. I'm pretty sure you can use Tasker to automate backups. I usually advise people to keep at least one backup or ROM zip on their phone, just in case.
IT HAPPENED AGAIN!
Per the ever hepful Heisenberg's recommendation, I wiped my phone and reflashed purenexus. This was yesterday. Everything went smoothly. Recreated my security PIN. Was able to unlock my phone with it without incident...until just now. Incorrect PIN error 3 times.
What is going on?!?!
It should be noted that both times this has happened has come after I turned my phone off. This time I happened to be charging my phone while it was off. I can't recall if it was the same case the first time it happened. Is this a purenexus issue?
found the solution.
"Delete this file /data/system/locksettings.db from TWRP."
I wish I had known this the first time it happened. Oh well. I sure hope this helps someone else in the future.

This is usually over necessary after a user has created (and later restored) a nandroid backup without removing lockscreen security first. Are you saying you hadn't done this at all prior to the problem occurring?

i dont know what qualifies as a nandroid backup. the only backup i created was with the TWRP backup function which i later moved to my laptop, as previously mentioned. and yes, i did that before the problem occured. it was before I had even installed pure nexus.
btw, it happened AGAIN (#3 for those keeping score). i'm going to assume there's a bug in the rom and forego the use of a security pin. also, for the first time, when i went back into twrp to once again delete the locksettings.db file i was prompted to enter a password before i could modify the system. Odd.

When making a nandroid (backup) in TWRP remove any pin, patter or fingerprints before backup or getting locked out will continue.

thanks for that, but i believe i did that because i backuped a clean factory 6.0.1, sans any security setup. not sure if that was necessary but that's what i did.

The problem isn't with the ROM, I (along with what I'm guessing is pretty much every other user) use fingerprint and/or PIN/pattern security on Pure Nexus with no issues. A nandroid backup is one of those backups you create with TWRP, so yes it's what you described. But this problem shouldn't be occurring on a clean flash of Pure Nexus, can you please explain in detailed steps how you installed the ROM?

On Marshmallow, the scramble pin option is bugged if you use a long pin. Some rom devs choose to leave this out entirely. I haven't played with it to determine the cut off point but 4 digits is fine. I think I tried 8 digits once and it locked me out.

Awesome.. Thanks a bunch for posting this... I am using Oneplus 3T , Resurrection Remix 5.7.4 ( Marshmallow) . Had turned on Scrambled PIN.. Ran into same issue as yours.. Last option left for me was to do factory reset from TWRP but I was scared to lose Google Authenticator Setup on my phone and many other things... Your solution saved me!! :good::good:
I also had a similar problem:
- freshly installed Carbon ROM with TWRP
- added lockscreen password in phone
- locked screen
- tried accessing using password
The password just fails. Using a shorter password works normally. The failing password is 13 characters long.
Mostly just out of curiosity I flashed a new ROM this weekend. I decided I like pure nexus better so I flashed my backup from twrp but wound up in bootloop. Even though I've never had issues restoring ROMs with MANY other devices, I still followed the directions for backing it up very carefully. I also did a full wipe before trying to restore it. In fact after the 3rd attempt I accidentally wiped internal storage. So that wasn't the issue.
Only thing I can figure is I was using elemental kernel when I made the backup so maybe that was the problem? I don't see why it would matter (or how that would work--removing the kernel, make backup, flash kernel again...) but I'm really stumped on how I went wrong.

Well Ive got the right guy to talk to Pretty sure it was what you suggested (system/data/boot/vendor boxes)
But I don't recall if I checked everyone to restore. However, I did store the backup on my computer. Even though I've since got everything back I can try again to restore it. But can you just confirm which I should check when I restore it?
I'll be certain to pay closer attention next time. Its just that this is one thing I had never struggled with. Thanks

Well yes. Thanks again. However, I've got something funky going on. Pin pointing is hard but yea the backup restored. Then I tweaked elemental kernel (nothing crazy, used stable profiles) maybe it was that and an xposed mod (thinking ifont because its one I only just started using lt recently). Anyway when I rebooted to install drivers for viper I got stuck in bootloop. This time I couldn't restore my backup. So I factory reset and reflashed pure nexus. Due to the time I couldn't try and restore the backup again but will try tonight. If I wasn't so hasty I could've deleted the modules list in twrp then maybe booted up but I'm not 100% it has anything to do with xposed. One other factor, it was using dark stock theme.
EVERYTHING I mentioned I've done/run on this ROM without issues but there's a combination of things that's causing the bootloop I think.
