Encryption Unsuccessful - Nexus 6 Q&A, Help & Troubleshooting

So I just recently received a new (to me) Nexus 6. Going through the process of unlocking the bootloader I forgot to do the command "fasboot reboot". I then installed TWRP and then booted into it. From there I rebooted the system and was brought to a screen that says encryption unsuccessful. I hit the reset button which brought me to twrp and asked for a password. I typed in "default_password", it did it's thing and rebooted to the same "encryption unsuccesful". I tried searching XDA as well as Google to no avail. When searching Google I found some threads for other devices but I didn't want to get into a worse situation than I'm already in so I thought I'd ask here before trying anything else. Any help would be greatly appreciated!
Update: I flashed the stock image (manually as the flash-all didn't work) and I was able to get the phone to boot up into Android. But whenever I reset the device it gives me the "Your device is corrupt" screen before booting into the system. And it seems like whenever I try to flash supersu or anything I'll get that message and then it just goes to a black screen and never boots into Android. I even tried to restore a TWRP backup and it still just went to the corrupt screen and then black. I was only able to get it to boot into Android after reflashing the stock images again. Is this a problem with the hardware or is there something I can do to fix it?
Edit: I've also noticed under internal storage it's only showing 23 GB available but this is the 64 GB model.

Did you format/wipe the system, data and caches - a complete factory reset ?

There are several things going on here.
1. Your device is corrupt message: This is a normal message that appears whenever you attempt to customize the device. It may also appear if there is an issue with the internal storage in general.
2. SuperSU: What version? You should be using the latest (2.76) or you risk having a bootloop.
3. TWRP: What version? Latest is 3.0.2-0. Older versions will offer to flash SuperSU. Don't accept the offer or you will enter a bootloop.
4. Internal storage: When you flashed the stock ROM you also flashed the userdata image in it, which caused you to lose half your storage. Simply wipe internal storage in TWRP to fix.
Your first thing is to fix your internal storage, which should be done through TWRP. From there, you will need to do a complete factory reset, as the failed encryption is the main reason you're getting a corrupt device warning. After the factory reset, restore the stock image, but do not flash userdata.img.

Thanks guys! Doing the factory data reset in stock recovery fixed it for me. It took about 30 minutes to complete, but now I've got root, twrp, and custom ROM and kernel with no issues.

always booting into TWRP, unable to enter into system. (solved!)

this is what i've done.
lenovo k3 note with twrp 2.8.7.2_K3_CUOCO92 and rom K3_LOLLIPOP_5.0_ROW_v1.12
i wanted to install one of the latest nougat rom. so i downloaded a twrp 3.1.1.1 made for the k3 note. i flashed the image from my old twrp and replaced choosing the RECOVERY partition.
Flashed ok, i tested a rom, AospExtended-v4.4-aio_otfp-20170708-1051- i flashed it and it worked.
OK BUT.............. i did not wipe the data partition because i received AN ERROR. the new nougat rom was ok but it was a superdirty flash with all the old apps that were crashing. what to do?
i enter into twrp, i REMEMBER that i had the data partition ENCRYPTED so i format it and after doing this i was able to do every wipe i want, included data.
OH PERFECT...... THIS IS WHAT I THOUGHT. i made a full wipe of the rom wiping 4 thinkg : data , internal storage, cache and dalvik cache.
reboot and BOOM. black screen. i press 3 or times the power button and the creen goes on... i am into twrp. from this moment i never returned to see my SYSTEM!
i tested other roms, same problem. i thought it was a twrp problem.... so i installed from the twrp an IMAGE of other twrp... i tested 2 or 3 other twrps specific for my phone k3 note.
I HAD LITTLE BENEFITS with another one.... just because when i press to reboot into system... the phone reboots into twrp AND I CAN SEE IT because the screen is ON, whilst with the "latest" twrp i found...... despites the flashing procedure was ALL CORRECT without errors, at the reboot i always entered into twrp...... BUT INTO A BLACK SCREEN MODE, like if the screen was on...touch enabled, but OFF backligt, and the only way to revive it it is to press power 2 or 3 times, to see the home of the twrp.
i've also found that on MOUNT.......... i always see SYSTEM unflagged, ok i flag it, reboot into system, actually reboot into twrp and system is UNflagged, i try the same thing ALSO flagging READ ONLY...... , idem reboot, twrp.
SEEMS THAT i cannot boot to system anymore. but..... if the twrp was fault, why for the first time let me flash the phone? i really entered into the nougat rom! i found all my old apps and files, but of course it was a DIRTY FLASH, i just wanted to make some wipes.....re flashi the rom.... but oddly i missed the possibility to return anymore to the system.
what could i do at the moment?
how to flash a original image? how to see if this recovery is ok? i donkt 'know where to find my answers......
ah last thing, while into the recovery i was always able to transfer files from pc to phone, but from minutes i am NO MORE ABLE to see the internal memory of the phone.
my computer does not see anything!!! so i am fukked i think....... i did not make anything different.
i only made a lot of wipes... a lot of flashing a lot of testin into recovery. i was able to see it from my pc and put new files through pc. now NO.
solved. i flashed with flash tools an old original firmware android 5.0, then i flased latest twrp with flashtool.... and then flashed the zip of a custom rom.

if u have backup then restore ur stock version or reeboot??

please help! Encryption Unsuccessful after update 5 with root

i tried to install the new update, and when phone restared i got massage Encryption Unsuccessful
i cant wipe, i cant flash nothing to phone because the phone cant find storage.
please help me!
Calm down, panicking is what may lead to further accidents.
Now, explain what you flashed after the (I'm assuming the OOS 5.0 File) update file. What add-ons did you flash? Any other audio mods or anything else?
What is your recovery? Which OOS version or ROM did you come from?

Had the same thing. I was lucky, because I backup all my data on my computer before update.
I was able to boot the system. I wiped it with stock recovery.
It ask for password and if u press "forgot password" u can wipe the whole phone. But it does a full wipe than. (Storage included)
An inconvenience at most but not the end of the world. Does it every time to me when I flash an Oxygen ROM. I'm always next to my computer anyway so I end up going ahead and just booting to download mode and doing a fastboot format userdata, fastboot flash recovery <twrp img>, booting to recovery, wiping everything, moving my data back to the phone, and proceeding with setting up the ROM... It's a big hassle and I know there's an easier way but I dunno...
If it doesn't find your internal storage or its only showing a percentage of your total (I have the 128GB 3T and it shows like 48 or 60GB total internal storage) you will HAVE to boot into TWRP and wipe your internal storage anyway to recover that space.. it's lost anyway, so not losing anything.

Can not install anything custom anymore, dm-verity gets triggered

Hello,
I have always been on root but somehow something changed.
Since I tried to flash the newest stable stock (5.0.1), nothing works anymore.
No matter if I flash dm-verity disabler, supersu or magisk, dm-verity gets triggered everytime and my phone just says "decryption unsuccessfull" and won't boot.
I've tried everything to fix this, including: different versions of supersu/magisk, reflashing TWRP recovery, even going completely back to stock, locking the bootloader and everything.
Also I read somewhere that you can flash dm-verity disabler and wipe data to completely remove the encryption, but TWRP showed an error message, something like "failed to wipe, cannot mount /data".
In the end I got stuck with no ROM and I couldn't even access stock recovery anymore because it had the weird password bug, so I had to use the unbrick tool to get it working again.
Can someone tell me what I'm doing wrong?
I have always been on root since the early Nexus 5 days, but now I feel really stupid because I must be missing something obvious, so thank you in advance for any help.
Cheers
What rom are you trying to install and what magisk version are you trying to flash over your preferred rom?
If by chance you are trying to flash OpenBeta 21, I have yet to avoid my data getting encrpyted when trying to flash. And personally, I must have been doing something incorrect ever since I got the phone, because almost every time I've flashed a stock OxygenOS ROM I have triggered encrpytion. In my situation it never seemed to matter if I flashed Magisk, SuperSU, a custom kernel, or even just a modified boot.img along with the disable encryption file... I don't know the steps you're taking, but what I do is this: once I get the "Encryption Unsuccessful" message when trying to boot, I just reboot to fastboot and type "fastboot format userdata". And since flashing stock OxygenOS usually overwrites TWRP with the stock recovery despite my best efforts to avoid it, I tend to go ahead and flash TWRP while I'm booted into fastboot. After, I boot into TWRP; at which point encryption has been removed, yet the total amount of storage available to me is less than 30GB (I have the 128GB model.) You have to go to Wipe, then hit the button on the bottom-right, "Format." Type "yes" in the box and format data. That restores my device back to 111GB free of 113GB. I then transfer over and flash Magisk and whatever other mods I wanted. After that my device is no longer encrypted and works just how I want it to. Hope that helps with your issue.
What rom are you trying to install and what magisk version are you trying to flash over your preferred rom?

If you're not using Blu Spark 8.61 TWRP, then I suggest you install it and try again.
If all else fails, do as @lordcheeto03 suggested and format userdata in fastboot - but note that this will completely wipe your data, including internal storage. Then install TWRP, then flash 5.0.1 and anything else you want.

If you're getting the encryption unsuccessful error, I don't think you format data in that manner, you gotta use fastboot and fastboot format userdata to remove encryption THEN boot into TWRP to do that.

Stuck on TWRP after attempted restore

Hi guys.
So after developing an audio bug on Lineage OS 15.1 (a story for another day) I decided to restore one of my old backups via TWRP (unofficial decrypt-friendly version).
I press restore, get some sort of error about mounting /system and then on reboot I get a message asking me to factory reset which takes me to TWRP. Not too surprised by this point because the Huawei bootloader is quirky.
However, when I go into TWRP, it simply gets stuck on the loading screen endlessly. I left it for several hours and it didn't budge. Rebooted several times.
I tried reflashing TWRP via fastboot, no dice, same result. I flashed the official recovery too. That loads fine, but obviously I can't restore with that because it doesn't support encryption.
So I'm a bit stuck here. I've read somewhere that it takes ages to load when you have plenty in the data and cache folders, which I do, but I really don't want to wipe because I have a full week of precious holiday photos and videos I wasn't able to back up (No access to a PC at the time).
Any advice?
Not sure how to fix the TWRP restore problem, but have you tried connecting to your PC while in TWRP? If I remember correctly, it'll allow you to connect to a computer so you could access your storage and backup the files you need.

Problem is that everything is encrypted, so even if it does show up it will be gobbledygook (nonsense).
Lesson to learn from this: always backup before trying to update ROM or flash something new.
I guess what you can do is to try to flash Lineage again and see if you can make that boot.

Yeah, there's a few reasons that happened. Usually I autobackup everything but I had been away from wifi for a week. I backed stuff up via Titanium but obviously that got encrypted too. Restores also have never given me problems in the past so I didn't expect anything to go wrong (still not sure what did).
Anyway, I'm not sure how to flash lineage without TWRP, especially with everything encrypted. To have any chance of getting it to work I'm guessing I'd need to flash it the same way I did originally, which was with everything decrypted which makes the issue moot. Maybe I'm wrong though.
Try flashing a treble rom via fastboot. Then wipe data and cache.
fastboot flash system "GSI. img"
fastboot erase userdata
fastboot erase cache
fastboot reboot

Thanks, but I'm trying to prevent loss of data. I'd probably just use e-recovery if I don't mind losing data and want to reset to start again from scratch.
Erasing userdata and cache is just factory reset. It won't wipe your internal storage which where your photos are kept.
Ok, turns out once I chose the "download latest firmware and stock recovery" from erecovery it didn't wipe the internal sd data!
Everything is still there and I can access it now from the huawei stock ROM even though I came from lineage OS. It thankfully does not reset the encryption keys or the pattern lock, so you'll be just fine once you do a system boot and go through the regular setup process.
I recommend this approach because it's pretty hassle free.

Glad you found a way to keep your files, mate

I got stuck in a 'recovery bootloop' and I'm desperately trying to rescue my data

Since I never had a problem with an update in years, and I'm also a very stupid person, I didn't backup my data before my latest custom rom (Pixel Experience Plus) update.
I got the notification for the November security patch updates, and I downloaded the zip as usual. For the actual installation I usually reboot my Mi 9T Pro into TWRP, flash both the OS update and Magisk, etc. and reboot. Everything seemed to go smoothly as usual: TWRP asked me to input my unlock sequence, then the usual stuff. Problem is, when I tapped 'Reboot system', it didn't reboot normally: it went into Recovery mode again, and from that moment on there's been no way to do otherwise. But now TWRP doesn't ask me the unlock sequence anymore and looks like there's no way to access the data. I tried injecting the recovery from fastboot, I wiped everything except internal storage (I don't give a damn about the OS anymore at this point); I also tried to reinstall the same old rom from OTG after wiping System, but nothing. Whatever I do, it always boots up in Recovery, and it doesn't ask me the unlock sequence. I know my stuff is still there, it's just that the contents of sdcard aren't accessible and look like random alphanumeric sequences from the TWRP file manager. And yes, that's the whole point of encryption, but I was used to TWRP asking me to unlock/decrypt so in the worst case scenario I would be able to access my data and copy via OTG. But now, with the system unable to boot and the recovery not decrypting my stuff, I'm starting to losing hope. I'm sure here on XDA there are much smarter / knowledgeable people than me, and I hope somebody can help me find a way to break the cycle and return in possession of the data that I stupidly didn't backup.
Any help would be greatly appreciated!
Try reflashing the boot image. Failing that, you should be able to ADB sideload the update via TWRP.

I think I tried both. I say 'I think' since my knowledge could fail here.
I tried re-flashing the TWRP img from OTG, nothing changed.
I successfully sideloaded the OS through ADB, but I'm still stuck.
Should I try both? (In which order)?
Thanks a lot.
