Yo. I got my Nexus 6P the other day and immediately flashed CM13 on it, and came across a couple of problems. I used the following guide, step by step: (Can't post links. but it's on Devs-Lab)
So, first off, after finishing everything (Unlocking the bootloader, Rooting & Installing Recovery and finally installing CM13) I came across a couple of problems. Firstly, my phone refused to start as it couldn't be decrypted even though I never encrypted it or set a password for the encryption (which it asked me for, to decrypt) so I tried to factory reset the phone. Didn't work, formated the phone which did work and now it launches / works with no issues. However, every time I start the phone it tells me that the device is corrupted and can't be trusted. What's up with this?
Thanks in advance,
Alex.
I don't have CM installed but what you are describing is normal. Read this:
https://support.google.com/nexus/answer/6185381?p=verified_boot&rd=1
Ah yeah, you're right.
But what about the encryption thing? It's sketchy as ****, I know for sure I didn't encrypt the phone myself / set a password to decrypt it.

And according to that thread, formatting your phone will remove the encryption. Which it did. Gotcha.
Last thing, why did it ask me for a password to decrypt? Or, why didn't I have that password? Mostly out of curiosity.

Thought I was good at this. Never mind.
So I have managed to brick my device after 6 hours of having it.
Managed to unlock the BL, install TWRP, but the OS has gone, and I have no way of getting the thing mounted to copy over a ROM or anything.
What's the best way for me to sort this out ?
I'm thinking I could buy an SD card, copy a ROM to it, then flash it via TWRP.
Is this the only option ?

If you can get to the bootloader then just use the restore to stock tool from shawn5162. Should work fine as long as you have successfully unlocked the bootloader. Here is the link http://forum.xda-developers.com/moto-x-style/development/windows-tool-moto-x-style-pure-edition-t3199905
Should be clear that this will put your device to LP 5.1.1 without root or TWRP. Then just do the OTA MM update and re-root and flash TWRP. You can follow this guide I created if you like.

Ouch...Thats a security feature on MM... Only way ive found to avoid it is to restore a backup and before you wipe/flash your next ROM either disable the lockscreen(i.e. unsecured lockscreen), re-enable OEM unlocking, or factory reset your device from it from your running phone(not in TWRP) through settings->Backup and reset...that removes your google account from your phone so once you reset it you can set your phone up with your google account

hmmm thats weird... the new security feature wasn't implemented until MM... The restore to stock should take you to 5.1.1. not sure what else to try. Hopefully you can get in after the wait...next time you get your phone running make a backup to save a headache down the road
edit: you couldnt use the restore to stock then before it loads flash a 5.1 ROM?

Its the stock TWRP backup from either 5.1.1 or 6.0....whichever you are currently supposed to be on.
wait, if this is a new phone and you had added your google account before "bricking," why cant you just sign in using that google account. My understanding is that the lockout is to prevent a NEW google account that was not associated with your phone from being used to set it up

That error means you don't have a 72 hour lock yet. Go to https://accounts.google.com/b/0/displayunlockcaptcha on your computer. Login, hit the accept button, then try logging in your phone. Your phone is not locked out, just to to the website. If you changed your password, though, then you shot yourself in the foot with the Google protection.
I'll make this as short and quick as I can. I had unlocked my bootloader, rooted my device and flashed a custom ROM(PureNexus) and TWRP. I had made a full nandroid backup and all was good.
Then the Android N Developer preview came along and I just HAD TO get it. So I used a tutorial on YouTube to ease the process and it went downhill from there. I used my fastboot folder and a command prompt to run the version of the file that wouldn't wipe my data.
When the device rebooted I noticed that none of my third party (downloaded) apps were working. I was upset and decided to just go back and restore my backup. That's when I noticed that I had no custom recovery anymore. I reinstalled TWRP, but when it loaded it told me my internal storage was encrypted. I tried the method of getting rid of all lock screen security and fingerprints but to no success. I also noticed that every time I reboot TWRP never seems to stick, I have to reinstall it through the fastboot folder and a command prompt every single time. I just wnna be able to get back to where i was and use my backup.
I'm lost on the situation, any suggestions guys? Any help is much appreciated

Flash the MHC19I factory images to get back to a stock configuration, then start fresh; flash TWRP again (the latest) and then flash whatever ROM you want to use.

Thank you for the reply and info. I actually just got an RMA request approved because my Nexus also had some hardware issues. So my question now is, will my phone being rooted, with an unlocked bootloader, and in this condition have its warranty voided? Or am I good to exchange it just the way it is?

The warranty isn't voided by unlocking or rooting, but you should return it to a stock configuration before sending it back anyway. Check out section 10 of my guide.

I need to recover data from a samsung galaxy s7 edge, but I don't know the code for unlocking the screen. There's a way to bypass this?
1. How could You forget a 4 digit pin code? Seriously.
2. Is it rooted? Any custom rom on it? Encryption?

It isn't mine, it was of a dead person and the family asks me to recover data but they don't know the pin.
It's fully original.
Then I'm not sure if it's possible.
If it didn't have encryption enabled (it's enabled by default by samsung) then You could flash TWRP and then flash a zip file which removes certain files in Data partition and well, unlocks the device (I've done it before when I broke my lock screen buttons). But with Encryption being enabled TWRP won't be able to read Data partition and yeah. I'm not sure if You can even access internal storage through TWRP.
Maybe try all possible combinations? Or the most popular ones.
Try this:
Flash TWRP(a detailed instruction is on XDA)
Tap on advanced and then file manager.
You should be able to see internal storage if it's not encrypted, and then just copy all files that You want to sd card or just mount usb storage.
But if the encryption covers Data and internal storage then I don't think You can do anything.
Like I said, in the worst case try using most popular code combinations and maybe one will work. But try that before flashing TWRP, cause TWRP might soft brick the device.
No. Who knows what you're really after? I'm totally against questions like these and would urge people not to answer. If it's really your own device, you have to deal with the consequences of forgetting a 4 digit number.
Not possible with encryption, only way is brute forcing it and it might auto wipe after 15 attempts
Really??? Xda is the first place someone with this situation would ask for help? First post? I'm calling BS.
If - hah - you are legit, the "dead" person's phone is still under warranty, therefore the "family" can take the phone to the dealer/network provider and get help there.
sounds very suspicious
Hi all,
Just ordered my OnePlus 5 and doing a little research whilst waiting for it to reply.
I'm struggling to understand why people would choose to disable encryption - have I missed something?
The only 'downside' to having it (that I can see) is having to unlock with a pattern/PIN at first boot (and when entering TWPR etc). I guess there will also be a slight performance hit, but shouldn't be noticeable.
The 'upsides' to having it are the added security if you loose your phone (and maybe Magisk needs it).
Removing encryption needs an extra file to flash after installing TWRP, and then having to format the user partition / sd card.
Any thoughts?
Cheers,

I second this opinion, I'd like to know before my device arrives tomorrow.
I did find a thread on the OP3 forums earlier, the read/write speed difference is negligible... So performance wise it doesn't make much difference.
My university requires an encrypted phone for Outlook though... Not a big deal as there are plenty of other alternate email apps available but it'd be nice to use for a change.

I remember reading something about not being able to restore data partition from a nandroid backup as it leads to bootloop and something about not being able to make a backup with security such as PIN, is this the case or an i mistaken?

As far as nandroid backups and the data partition restore causing bootloops, there is a TWRP beta version released where the dev is asking for someone to test if it is fixed. As of that threads current posts no one has stepped up and confirmed if its fixed one way or the other.
You are correct that it is recommend that before you take a nandroid backup that you need to change your lock screen security to swipe or none. Otherwise a restore causes bootloops but there is a documented workaround using TWRP.
The workaround results in your lock screen security being removed (specific files are deleted). What I don't like about being forced to remove the lock screen security to do a nandroid backup is that it also wipes all your finger print input. Re-entering a pin number or swipe, is not much of a bother but doing four fingerprint training each time I want to take a safe nandroid backup is a pain. Previously I liked doing a nandroid backup at least once a week now I'll only do it when I feel any system changes (e.g. OTA, ROM flash), will put my phone at risk. With that being written I will still remain encrypted at least for the foreseeable future.

Is there not some kind of system-app that holds this info, that we could back-up with Titanium, and restore after taking the Nandroid? Still a bit of work, but at least you'll be consequent.
Encryption is automatically enabled if you set up any sort of screen lock (PIN, etc). Booting into recovery gives you a password prompt by which the PIN does not work as a decryption password.

So how do you decrypt to access files from within TWRP recovery? Given this is needed to do backups (which are working, according to the TWRP 3.1.1 thread) there must be a way.

I went from 4.5.0 to 4.5.3. I don't know what makes it work for me (I remember that I had issues just like you did on 3T).
From what I've gathered, you must remove pattern/PIN protection (I'm assuming this disables encryption?) before creating a backup via TWRP or else it will be impossible to decrypt (even with the right pattern/PIN), requiring a factory reset, which kinda negates the whole point of a backup. As long as you remember to do that (or TWRP for the OP5 matures a little more, it is after all only a few days old at this point), there isn't really a reason to disable it.
Also, any non OxygenOS based ROM will need the data to be decrypted for it to boot.
There are a few reasons to decrypt, but if you have to ask why you should or shouldn't, then you probably don't need to decrypt if the first place, so don't.
So I need to decrypt in order to flash roms?
Not, there is no reason to. Bare in mind I always decrypted my phone's
The trade off just isn't worth it.
Run a script is enter a password, either way you have work to do.

Hi,
I've just set up my Axon7 from scratch, after it returns from service, and set up new unlock pattern. I admit, I must've been drunk or something, because can't remember the pattern itself. Currently I unlock the phone with fingerprint sensor.
Is it possible to change/remove the unlock method without factory reset? As I said, the phone reads my fingerpritnts fine.
Thank's for any advice
1. Boot to TWRP
2. In File Manager go to the /data/system folder. Scroll down and find the two files with the .key extension. Delete both of them (by tapping on the file and then tapping the <Delete> button). Then, delete all the files containing the word locksettings:
gatekeeper.password.key
gatekeeper.pattern.key
locksettings.db
locksettings.db-shm
locksettings.db-wal
3. Reboot system.
