You can successfully get on VPN through WiFi. GO to your VPN client click on connection entries drop menu at the top, then click modify, go to transport tab, and click to check the box enable trasport tunneling. Once you do this save it and you should be able to access it. I was successful.

[Nexus 5X Q&A, Help & Troubleshooting] thesebastian:
Hi

My Nexus 5X is arriving this week. I had many nexus devices before, but now I saw that you can add a password at the startup of the phone and I wanted to know how this is working with an unlocked bootloader.

In the Nexus 5 (2013) I used to keep my bootloader closed because with the bootloader open there was a risk: you were able to install (fastboot flash) or boot (fastboot boot) a CUSTOM recovery and flash things without wiping data, or even, access the internal memory of the phone from the custom bootloader. (This didn't happen with the locked bootloader because you were forced to wipe /data before flash a custom bootloader).

So now, with the 5X and the startup password, how does it works with an open bootloader? If I open the bootloader, the only way to flash anything is knowing the startup password? Or you can access fastboot mode without any password and good to go?

If that's the case, then I think I'll keep my bootloader locked!

I'm asking this prematurely because I don't want to install everything, and then wipe to open the bootloader, and start from scratch again.

Thanks

Sebastian!

Thanks Oblox. Then I think I'm keeping a locked bootloader for now!

I don't understand why they don't request a password to access the bootloader.... it could be much more secure.

[Nexus 5X Q&A, Help & Troubleshooting] Oblox:
Agreed in principal, security concerns raised by unlocking the bootloader would be much less of an issue if they allowed it to be password protected.

However id imagine it would cause headaches when flashing new bootloader (Where does the unlock info sit?) and when ADB'ing via usb etc that are too much effort to address. Id imagine most users dont ever unlock so dont suffer and 'developers' who do are suitably warned.
[Nexus 5X Q&A, Help & Troubleshooting] sfhub:
It depends what you are trying to protect.

When you boot the phone it will pick some random key and encrypt your user partition, so your user partition is ALWAYS encrypted using a private randomly generated key.

Then if you don't select a pattern, pin, or password, that random key is (rather than being stored in plaintext) encrypted using the default string "password" plus some phone specific information accesible on the phone itself.

If you do select a pattern, pin, or password, then the random key is reencrypted with a process that includes your pattern, pin, or password.

In this way, when you change your pattern, pin, or password, the whole user partition does not need to be re-encrypted, just the random private key used to encrypt your user partition needs to be re-encrypted.

The password you enter upon startup is to unlock/decrypt the user partition.

So if you have unlocked bootloader, someone can steal your phone but can't get access to your data easily unless you leave the phone with no pattern, pin, or password.

They can overwrite your system and boot partitions, but if you have pattern, pin, or password when they try to factory reset your phone there is some Android factory reset protection that will ask them to enter your pattern, pin, or password when the phone connects to Google. This actually often locks users out of their own phones when they forget the pattern they used because it was just temporary when they entered it or it was an old pattern they used a long time ago and it comes back on factory restore.

The best they can hope for would be to install custom boot/system images and trick you into giving them your pattern, pin, or password, prior to stealing your phone.

So it really depends what you are trying to protect.

Locked bootloader, on the other hand, if you mess things up, can be a big impediment to fixing your phone.

My suggestion would be to unlock your bootloader, create a pattern/pin/password, and leave Nexus factory reset protection turned on.

Good flexibility with reasonable protection.

The password you enter at startup is so the kernel can finish the boot process, otherwise it cannot read your user partition.

You'd need to enter that password when running TWRP custom recovery as well or it won't be able to read your user partition.
[Nexus 5X Q&A, Help & Troubleshooting] SlimSnoopOS:
Just one thing to add onto the words of everyone else. This is my first Nexus but it is my understanding that previous Nexus devices have allowed users to lock/unlock the bootloader on the fly via an app. If this is something you intend to do, you should be aware that does not exist on the 5X. The bootloader must be unlocked after enabling OEM Unlock in Developer Settings. You can now install sideload OTAs from Google's website though.
[Nexus 5X Q&A, Help & Troubleshooting] thesebastian:
Thanks you very much for all your posts.

I think I'll stay with a locked bootloader for now. At the end of my N5 2013 life I wasn't really using root features. Later I spent too much time with a Z5 Compact where opening a bootloader has bad consequences. So now I'm pretty much used to closed bootloaders.

So considering that fast boot and recovery mode don't need the startup PIN I'll stay with a locked bootloader.

However I already got a reason to unlock the bootloader. If there's any way to record videos in FHD@60FPS I'd root the phone.

[Nexus 5X Q&A, Help & Troubleshooting] roofrider:
I think sfhub said that you'd need a password to boot into the recovery as well. So unlocking your bootloader and leaving the phone encrypted with rest of the security features turned on does seem quite secure than i initially imagined. Too bad I never stayed encrypted long enough to play around with these.

But does it still ask for a password if you flash a different/custom recovery? I'm guessing it will, assuming the passwords are located on /data partition which is encrypted.

That said, someone in PN thread mentioned that knowledgeable hackers can still gain access to an unlocked, but encrypted phone via methods I'm unaware of. But I'd say it is very unlikely that my phone will end up in the hands of someone with such abilities.

The conversation is here: http://xdaforums.com/nexus-5x/development/rom-pure-nexus-layers-fi-wifi-calling-t3244601/page351
[Nexus 5X Q&A, Help & Troubleshooting] sfhub:
You don't need a password to boot into Recovery. You need to enter a pattern/PIN/password into TWRP (TWRP's UI is the one presenting the UI to ask for your password) to allow TWRP to mount your user partition as without that information the user partition is just gibberish.

Whether the different custom recovery asks you a password or not will depend on the custom recovery, but if your recovery doesn't ask for a password, then that recovery has no ability to access your user partition as it won't be able to decrypt the contents. Even if it does ask for a password, sometimes it can't access due to mismatch in decryption procedures. Some earlier versions of TWRP had this problem.

If you leave your bootloader unlocked (especially if a bad actor has physical access to your phone), if someone is determined enough they can eventually get access, but with current features it is significantly more difficult/annoying (compared to how trivial it was prior to encryption) to the point most normal people won't bother:

1) AES encrypted user partition

2) multiple password failure reset

3) mixing your pattern/PIN/password with phone specific salt

4) factory reset protection

5) remote reset

The easiest way for them to get access to your phone is to install a custom android or recovery that records your pattern/PIN/password and getting you to enter that information on your own, prior to stealing your phone.

I am guessing multiple password failure reset can be bypassed with bootloader unlocked, so brute force is likely easier.

Now if someone comes out with tools to automate brute force of phones with bootloader unlocked then you might only have real protection from brute force if you enter a complex password rather than pattern/PIN. This still wouldn't protect you from having someone replace your recovery or OS with something that records your pattern/PIN/password but it would protect against the most likely case of someone stealing your phone and trying to access your user data.
[Nexus 5X Q&A, Help & Troubleshooting] thesebastian:
I have another question

Can you open the bootloader if the phone is encrypted and with startup pin/password?

If so (I assume yes) /data is wiped and then the phones encryption is reserved? (Just like out of the box)

Sent from my Nexus 5X
[Nexus 5X Q&A, Help & Troubleshooting] sfhub:
I assume you mean "unlock" the bootloader.

The answer is yes and no.

You must first go into developer options to allow OEM unlocking.

If you have a locked bootloader and set up a pattern/PIN/password, then for somebody else (w/o your pattern/PIN/password) to enable OEM unlocking would prove to be a challenge since they can't easily get past your Android login and I haven't an easy way for them to enable it through other means.

Assuming they can get past your pattern/PIN/password (or you just left OEM unlocking enabled yourself) then yes, they can unlock the bootloader and it will enforce a data wipe in the process.

Android factory reset protection might also kick in after the phone connects to Google and they may be forced to enter your pattern/PIN/password to access your system.

I don't know what you mean by "encryption is preserved" The user partition starts off unencrypted. Upon first boot, the kernel will see it isn't encrypted and will encrypt it. From that point on the user partition is always encrypted.

If your data gets wiped due to bootloader unlock, the user partition will be erased, reformatted (at which point it'll be briefly unencrypted), then will be re-encrypted upon first boot of kernel.
[Nexus 5X Q&A, Help & Troubleshooting] thesebastian:
Oh yes sorry! I totally forgot about that option under dev settings when I asked the question. So fastboot oem unlock will never work without knowing my PIN (I never had this the Nexus 5 and older Nexus).

That means that a Nexus 5X with a locked bootloader and that option disabled is completely useless for a thief? (Without including advanced concepts like "change the internal memory") Or you can still rewrite /data with a locked bootloader and get rid of the encryption?

(This applies also for the stock recovery "wipe data" function?)

These last questions I've made are not about privacy, are more about anti-theft features.

Sent from my Nexus 5X
[Nexus 5X Q&A, Help & Troubleshooting] sfhub:
I think "useless" is in the eye of the beholder.

IMO with locked bootloader, OEM unlock disabled, pattern/PIN/password created, standard encryption enforced, it would be extremely difficult to access your data.

They could boot into recovery and reset your user partition, but in that case, they wouldn't be accessing your data and upon connection to google will likely get hit with android factory reset protection and need to enter your pattern/PIN/password to access the phone.

They may be able to force LG recovery mode and rewrite your phone. I don't know what happens with Android factory reset protection in this case, but they won't be accessing your user data unless they can easily break AES-256 brute force (which is not really possible today unless your keys get compromised through social engineering)

I think worse case, with a bunch of work, they might have a functioning phone that will lock them out if they ever connect to a network. They can probably sideload some games and use it for that.

---------- Post added at 12:24 PM ---------- Previous post was at 12:08 PM ----------

One other thing, keep in mind this is how things are designed to work with all the chains being secure (bootloader, kernel, recovery, android, etc.)

There could always be some zero day bug that could be exploited to break the design. If there was a kernel memory overrun bug that wasn't patched, that could potentiall be exploited to replace the code that resets the phone upon too many mistaken password entries, and then that combined with a 4 digit PIN code might result in a brute force attack on your PIN being feasible, there are only 10,000 combinations to try.

That is similar to what happen with the San Bernardino iPhone case. They were able to disable the phone reset after incorrect PIN entry functionality then just brute force the PIN.

So if a thief get my phone and do a wipe data in the stock recovery. The phone is still encrypted? They can't add a new Google account and use it like an out of box Nexus?

IIRC they may be able to factory reset using stock recovery (or Google could have enhanced stock recovery to ask for pattern/PIN/password as well) but upon connection to Google it'll reinstall pattern/PIN/password.

So they can probably get the phone to be usable until they connect to Internet at which point it isn't usable. How usable your phone is without a network connection is debatable.

If Google has enhanced recovery to ask for pattern/PIN/password then they couldn't even get that far, unless they somehow force LG recovery mode and use LGUP to overwrite the phone.

I would test this all out for you but I don't have a phone I can spare being used as a test right now.

No problem! Thanks for the answer. Really helpful.

This is also useful in case I wanted to buy a used Nexus phone. (Well I bought mine directly from "Amazon Warehouse deals" but I could had used Wallapop who knows!)

I assume that a Factory Reset made by the legit owner from the "Settings" menu and not from the "Recovery" is enough to make the Nexus "tradable" again.

[Nexus 5X Q&A, Help & Troubleshooting] sfhub:
Ok, I think you jogged my memory.

I believe what happens is this.

When you tie a Google account to your phone, it sets some information in the UEFI bios storage area (or some other area that survives factory reset). When you factory reset from recovery, during the initial setup it'll force you to connect to the most recent account associated with the phone (normally upon initial boot, it won't force connection of Google account)

This tends to hit buyers of used phones when the seller factory resets their phone right before selling it without removing pattern/PIN/password and removing google accounts.

So the proper way to sell a phone is

1) remove pattern/PIN/password

2) remove all Google accounts associated with this device

3) factory reset phone

Every manufacturer might have slightly different factory reset protection routines. I believe some states passed laws that required devices have ability to be remotely locked in case stolen and all this is part of that infrastructure. You can look at that as government wanting control over locking your phone or government trying to reduce the value of stolen phones for your benefit.

I think even Factory Reset from settings can experience the problem of new buyer needing to connect to previous google account, so best to remove pattern/PIN/password and Google accounts. I believe just removing the pattern/PIN/password will remove factory reset protection and similarly removing Google account will to, but I am not absolutely sure, so best to remove both.

I know you asked from standpoint of buyer and I responded from standpoint of seller. If you purchased a used phone, you should remind the seller to do the proper steps to disable the factory reset protection. I think factory reset protection started in in devices that were pre-installed with 5.1 or higher.

If folks forget to remove factory reset protection, they'll need to contact the buyer and give them their Google account password so they can complete set up and un-associate the account from the phone. Also don't reset your Google password then give the other user the temporary password, hoping to then reset your Google password back to standard, because there is some freeze I think 24 or 72hours where you can't use the account for initial setup if your password just got changed.

[Nexus 5X Q&A, Help & Troubleshooting] sfhub:
I asked a friend who went through this trauma and he confirmed that if you change your Google password, there is a 72hour (not 24hour) lock before that password can be used to unlock a phone that has been factory reset.

Further, everytime you enter the wrong Google account/password on the phone the 72hr timer is reset.

So if you are in this situation best to just let the 72hr cooldown period pass before attempting to get into the phone. Spend your initial time making sure you have the correct Google account and password that was associated with the phone in question, then just wait it out.
