I have had some issues with my phone since unlocking with sunshine. See separate thread http://forum.xda-developers.com/droid-turbo/help/help-bricked-xt1254-unlocking-to-t3279581 for description. I have a theory about this now and would like some opinions from folks with more experience.
I used device encryption on my Turbo before the OTA update to Lollipop. After encrypting the phone I would be prompted to enter my PIN to decrypt the data partition before the phone would boot, and then I'd have to enter the PIN again after boot to unlock it. After the OTA I no longer had to enter my PIN when booting the phone, but I would still have to enter it after boot to unlock. After the OTA the phone still reported that it was encrypted in the system security settings even though it didn't need a PIN to decrypt at boot time. That makes sense from what little I know because encrypting the device re-writes the data partition, and the OTA didn't touch the data partition and could not un-encrypt it. I was baffled by this, but I didn't want to factory reset and wipe the data partition to let me re-encrypt the phone.
So after the OTA, the data partition of my phone was still encrypted, but magically the phone was able to decrypt data and boot without my PIN. I don't know why. But one clue is that after unlocking and installing TWRP I looked at TWRP log and saw a log message saying something about decrypting with default PIN. Anyway, I never wiped data, but my phone somehow manages to boot. Re-flashing system and recovery caused problems at first, but now it seems to be back to the way it was. I haven't flashed a new ROM yet, but I expect that when I do I'll have to wipe data and that will get everything back to normal.
My question is has anyone else experimented with device encryption and is this behavior expected?
Thanks.
Not having to enter a PIN with the factory image was a bug I initially discovered, and reported, during the *initial* Android L SOAK test. Needless to say, they never fixed the bug (plus one of the Stagefright CVEs) during the second SOAK rollout. I reported it then, too. They did nothing. That second SOAK was the straw that broke the camel's back, for me. I will never participate in another.
As far as this bug goes, what I would do, is an FDR, and re-encrypt your device to wipe the key store and start over.

I got notifications that the SU4TL-49 OTA was ready to install on my phone, and I had read that if you try to install it with anything but stock recovery that you get into a boot loop. I figured it was a matter of time before I ended up accidentally installing the OTA upgrade and so decided to wipe my phone and go back to stock, and I would use that opportunity to re-encrypt the phone. It took me a couple of tries before I discovered that factory reset isn't enough to remove the encryption, and that I had to reformat the data partition. This took a few hours of going back and forth between reverting to stock, upgrading, rooting, configuring and starting over before I finally got it right, but eventually the phone said that it wasn't encrypted and gave me the option to encrypt. What a pain. After setting up all my apps for the third or fourth time I thought I was done. Whenever I rebooted I was prompted for my PIN before android booted. I even had to enter my PIN to run TWRP.
At least that's the way it was for a few hours. Now when I reboot it just starts up android with no password again. All the effort to un-encrypt and re-encrypt seems to have been a waste. Oh well, at least I avoided getting into boot loop hell.
Hopefully this unencrypting without requiring password/PIN thing gets fixed when (if) they come out with M for the turbo.
This just keeps getting better and better. I decided to flash the Unofficial CM13 ROM this afternoon just for fun. I got it all set up when I found that the GPS receiver wasn't working. Searching the thread I found a link to a flash-able radio image to fix that, and when I rebooted to TWRP it prompted me for a password to decrypt the data partition! Unfortunately it didn't like my PIN no matter how many times I entered it. I don't know if there's something about entering a numerical PIN on the qwerty keyboard, but it had worked earlier in the day before it stopped prompting for passwords. After a bunch of tries and reboots I gave up and downloaded a fastboot flashable version of the same. I've spent most of the day screwing around with this phone already and I'm not going to reformat the data partition again today for sure! Maybe it just needs a good night's sleep.

Encryption is totally broken on CM13. The issue is that our version of TWRP cannot decrypt it. I contacted the maintainer of TWRP for our device about this issue and he said that he tried to fix the issue, but he failed.
Also, official CM13 has been out for a while now for the Turbo. No need to go with the unofficial version.
Thanks for the info @TheSt33v, but I'm not sure that it's totally broken.
The strange thing is that I was using TWRP 3.0.2 just fine after encrypting phone while on stock ROM, and it worked for a while even after flashing CM13. Then it just stopped liking my PIN. But CM13 takes my PIN and decrypts data just fine. So my phone is usable for now, and the problem of it decrypting without asking for a PIN is solved for now. I just went to cyanogenmod and see that there's a CM13 recovery. Based on your post I'm guessing that's what is broken, so no point in flashing that. Oh well, at least my phone is secure.

Just FYI, our TWRP maintainer has fixed decryption. You can get the latest version here: https://www.androidfilehost.com/?w=files&flid=39562 (version 3.0.2-0 mod 02 as of this writing). I still had trouble decrypting a partition that was previously formatted using the stock recovery menu, but once I formatted the data partition using this version of TWRP and re-encrypted, it decrypted fine.

Yes they have fixed it! I found TWRP Mod 2 over the weekend and saw from the change log that decryption was fixed. I flashed it and it works great. No problems decrypting my previously encrypted data partition since I flashed mod 2. The funny thing about it is that basic TWRP 3.0.2 (no mod) worked well enough for long enough for me to flash CM13, and it even seemed to work for a little while after that. But then it decided that it didn't know how to decrypt my phone anymore and I was stuck until Mod 2. I can't explain why it worked for a while and then stopped, but I'm very happy that mod 2 fixed it.
Thanks for your help and support. Sometimes I feel like I'm the only user who encrypts his phone. There don't seem to be a lot of threads about encryption/decryption issues.

Most people don't seem to think it's worth the impact that it has on performance.
I was worried about the performance hit too before I tried it. But I don't notice any real difference in performance. Of there is a hit it's too small for me to tell.

This is a very interesting thread. I would like to encrypt so I can setup my work exchange email as its a requirement. Just to clarify what is the order to do this in? Currently I am running RR 6.01 but have run CF's 1.3.6 ROM most of the time as its awesome.
Can I encrypt using RR or do I need to switch back to CFs ROM or to stock Lollipop after installing the upgraded TWRP in place of the standard version I am running now?
thanks for the help and information.

You can encrypt on RR. Just make sure you're running TWRP version 3.0.2-0 mod 2: https://www.androidfilehost.com/?w=files&flid=39562
If encryption fails, you'll need to format your data partition (aka do a factory reset) using this version of TWRP. Then it will work.

thanks so much for the clarification! Being encrypted, how does that affect installing future updates or restores? Can I still flash ROMS and other ZIPS from TWRP the same as now?

The only difference is that you'll have to enter your password/pin every time you boot twrp. Don't try to use a pattern lock. Everything else will be the same.

thank you for the help! I was able to encrypt my RR MM install without having to wipe the data partition. It now prompts me to put my PIN in when booting up and when going into the modded version of TWRP. It then is able to decrypt the partition in TWRP so as you said just like before. Only difference is a little longer boot up time. Performance seems the same to me.

Guess I spoke too soon. phone was working fine for a day. Yesterday at work I'm looking at my phone as it reboots on its own (just sitting there). I then get cant decrypt partition message. Cant do anything and it wont boot up into the OS WO giving this error. In TWRP still cant do anything because it cant decript the partition. So I formatted the data partition and started over. I had saved a recent backup to my PC so I was able to get back to that. Now running CFs latest instead of RR. I need my phone, cant take a chance on this happening again as I was instantly dead in the water. Just wont encrypt.

Well, just as you used CM13 Marshmallow and RR Marshmallow just fine without encryption, not sure why you went to CF Lollipop instead of RR just because encryption didn't work. It just seems you were implying it's CM13 or RR at fault when you used them just fine before, and even now on CF you are NOT using encryption.
But it's your phone, so you can run what you want.
I do commend you for having a recent backup on your PC.

I should have clarified, I dont think RR had anything to do with my issue. I actually really liked RR, it has some great features, great performance and good battery life too. I just missed the Moto features in the stock and CFs ROMs.

Strange. I've been using RR M encrypted for several weeks now with no issues. Oh well. If you're happy with modified stock, that's all that matters. You can encrypt that too if you like. I'm a big fan of the Moto features as well, and RR M has basically all of them built in besides Voice (chop chop flashlight was removed for a while, but it has been added back). Although I've never understood what Voice offers that Google Now does not.
Mystery solved!

I have been running the CM13 ROM for the past few months and it's been great, but now that Verizon came out with official Marshmallow I decided to go back to a stock-based ROM again because I've been missing VOLTE. So I flashed ComputerFreak274_MM. After flashing and rooting I was back in the stupid state of the phone saying that it was encrypted but booting without a PIN. It seemed unreal that Moto/Verizon would have left this bug in MM too. So I reformatted data, re-flashed and rooted the ROM and tried encrypting. Then I discovered that it won't encrypt if it's rooted. So back to wiping, re-formatting and flashing again, but this time I am able to successfully encrypt before rooting. Success! Now root and start setting up the phone. Now I have to enter my PIN before it will boot into the system or into TWRP. Yay! By now it's 1:00am and I have to be at work early, so I let it sit overnight while my apps download. In the morning I flash SuperSU and notice that I wasn't prompted for a password to decrypt when I booted into TWRP and I wasn't prompted for password when booting system after flashing SuperSU. WTF!!! More time wasted. It seemed that stock ROMs just don't like encryption. :crying:
Anyway, after stewing about it all day I randomly chanced into the solution. In the Security settings menu there's an option under Encryption called "Secure start-up" which only becomes available when phone is encrypted. The Secure start-up options says:
"You can further protect this device by requiring your PIN before it starts up. Until the device starts up, it can't receive calls, messages, or notifications, including alarms. This helps protect data on lost or stolen devices."Secure start-up defaults to disabled for some reason, and when it's disabled the phone automatically decrypts itself when it boots without requiring PIN entry. So you can encrypt your phone and still be totally unprotected. What a dumb-ass default!
But when I enable Secure start-up then encryption works the way it should -- with phone prompting for PIN before booting. Maybe I just didn't notice it, but I didn't see anything when I encrypted the phone saying to enable Secure start-up to actually protect the phone. I'm guessing that this option was there in Lollipop too; but who knew???
I am being plagued by wifi issues ever since i went to a new version of Purenexus. It seems to have something to do with going to 7.1.1
I've tried the older version of the rom that was working fine before, but i still seem to have wifi issues even in these older versions now.
i tried resurection remix, but still have the same issue.
after a while the wifi wont be connected and it says authentication problem, or sometimes shows it as simply discconected.
i can manually forget the network and re add it and it seems to work fine for a while.
Durring troubleshooting today, i have tried to resey my router, even upgraded the firmware,
anyways, i'd like to flash the factory image to test to see if i still have issues. but i want to make sure that if i install 7.1.1 factory image, or 7.0 that i can still re-flash twrp from adb or am i going to have to find a root exploit?
if i flash a factory image does it "relock" my bootloader? i guess that is the more important question
thanks.

There will be no locking of the bootloader unless you issue the command. No exploits needed. Just flash away...
As of right now I am currently using FreedomOS CE 2.11 (7.1.1). It was the only rom I had on my hard drive that I knew would work. I own the OnePlus 3T for any of you curious. Here lately I have had some issues in getting certain roms to work. I'd go through the whole process of flashing: to include a clean wipe of everything. I'd flash the rom and get no working data whatsoever. That's the first issue. The next question I have is why exactly would I need to encrypt or decrypt my one plus 3t? I have heard it's for multiboot, but I've never had any reason to use two roms at once. I had an issue with liquid rom 8.1 earlier where it was asking me for a password during the initial bootup, so I entered 0000. A few moments later I got a message saying decryption successful, but wanted me to reboot into recovery for some reason. I've also experienced the password problem using stock recovery, but I haven't seen that in a week or two. I mainly used blu recovery or twrp (latest versions).
I can't say why others decrypt their phones, other than to avoid the inconvenience of typing in a password, but I always have my data encrypted so that, if I lose my phone, no one else can access the information on it.
I also always use a password (not pin or pattern) and require it to boot the phone.
Without this, because I have an unlocked bootloader, anybody could use TWRP to delete the password files and then boot the phone and have access to everything on it.
I have not decrypted my phone since I bought it a year ago. And have never had issues with passwords because, I'm guessing, I set it to be required on boot. I've used different versions of TWRP and ROMs all without problems.
So I have a Moto E5 Plus (hannah) XT1924-8
and I'm in a jam.
I'm new to moto phones I just moved over to this phone 4 days ago from my HTC M9 yeah I have been a HTC guy for a long time.
My stock rom is fubar, when it boots up I get that encrypt storage thing & reset phone etc.... (no password box) but reset phone is not fixing it.
The boot loader is unlocked
& my twrp is on twrp-3.2.3-0-hannah.img got it from twrp.me
So my problem is that I want to re-flash my stock rom but "Lenovo Moto Smart Assistant" witch did worked 4 times this week but now does not want to work anymore.
It comes back at me with "this device is not supported" & that is not true.
So Now I can't get back to stock & I have not been able to get any custom rom to work me as well.
So my ?s to all of you:
Is there some kind of fix for the "Lenovo Moto Smart Assistant"?
and if not then where do I get a copy of the stock rom & some info on how I should go about installing it
and yes I have the newest adb all installed & I think I have the right driver installed "Motorola_Mobile_Drivers_64bit_v6.4.0.msi" Motorola ADB Interface 7/7/2013 v2.0.2.0
Any help will be much appreciated
Also is the phone default encryption getting in the way of me installing Lineage 15.1 or Bootleggers ??
When ever I try to installing a custom rom I get the dreaded 'To Start Android, Enter Password'
also in twrp /data does not mount when ever I booted into twrp, I had to change the format from ext4 to exfat & then change it back to ext4, from that point on it mounts no problem.
My HTC m9 phone did not have encryption on so I'm not use to working around it.
Well I'm going to return this thing & stay with my HTC m9 with only a 10% working battery.
It seems that no one is going to help me.??
there might be reasons why people wouldn't respond
1. this board isn't active like you'd expect it to be
2. there's already threads out there to save yourself from this
anyway, on twrp, you'd need to FORMAT data to have it de-encrypted... and you'd need to flash a certain boot image that prevents it from auto-encrypting, which is in one of the threads. you'd also never would want to use the smart assistant, because as you can see, it won't work. i don't know if there's a stock rom for your variant, so i can't really link you to yours, but getting it from the moto assistant isn't ideal, it's better to get it from here on the forums or something.
so, in order to install a custom rom, flash the boot.img that doesn't have encrypt, and then flash the gsi system image, and then flash magisk in twrp.
There should already be a thread with the xt1924-8 stock firmware in here somewhere just gotta search. If not I'd suggest trying to re-flash the stock recovery and boot images if you have those and then just try to do a recovery from within.
well I already returned it.
I did read many many many guides on here & on other websites before asking for help.
most of them did not say anything about the book.img to turn off the auto-encrypting.
again I never had to work around auto-encrypt before.
Also @wihzard
I did look for a stock rom for (hannah) XT1924-8 but did not find it.
anyways I returned it & now I'm looking for a unused M9 to replace my old one,
I will end up putting LineageOS 16.0 on it.
Thanks for replying
my moto e5 plus is bricked im pretty sure ...any help anyone?

I need help as well haven't had much time to get on here and try to get help. I have the XT1924-7 varriant. I had discovered a hidden network that was placed on there by an ex to track me. So I factory reset I had AEX pie installed on it. Come to find out factory reset didn't even get ride of had to follow some extra steps to erase partitions that weren't wiped during the reset with TWRP. So my problem is once booted and going through setup process these pop up start popping up(screen shots below)the first is the modem keeps stopping. I get that about 25 times of hitting ok then I get one last one stating internal error need to factory reset. IVE DONE THAT COMPLETELY DELETED IT ALL RESTORED ALL. I've flashed NON-HLOS alone withe the erase modem 1&2. And still I've done diffent methods of trying to restore and get nowhere. Any help would be appreciated
Hi. I got an unknown CSC unlocked N960F/DS from ebay sometime back in late 2019. As soon as it arrived, I dumped lineage on it and was mostly happy with it for a while. Various features eventually went and broke(bluetooth most of the time, photo uploads in any apps basically) and yesterday I decided to upgrade my rom. I went and downloaded one of the lineage builds and sideloaded it through adb. That's where the story begins. My phone didn't make it past the brightness reloading part of the bootloader screen. I went through some other builds but that was obviously hosed so I grabbed the ONEUI2 STABLE rom and devbase rom from the exynos section here. I flashed devbase and while my phone worked, I had no cellular, my launcher was constantly crashing to the point where I couldn't use it, and bluetooth was also constantly crashing. I did the same with the ONEUI 2 STABLE rom only to be stuck at the SAMSUNG + blue/cyan LED screen after optimizing apps.
I don't really know where to go from here, but I guess I really don't want to trash my userdata. There's a lot of **** there that I can't really get back if I wipe it(avid user of signal).
Note for all you folks in back:
This wasn't actually a EFS related problem. I had a CP/BL vs. system mismatch and the firmware i was using simply didn't use the baseband. I flashed back to stock, BRI CSC and was perfectly fine. I'll probably restore my data partition from a backup in a few hours.
Obvious PSA that saved me a lot of time:
BACK UP YOUR EFS!!!!!!!
