I've read that some people like to install twrp, root, etc. and then re lock the bootloader. Is there any benefits to doing that? And is there a way to unlock/lock without wiping every time you unlock again?
It's better to relock it as if your phone is lost or stolen unlocking it ends up wiping the phone. Your data is safer.

Which kind of forces you into a clean wipe each time you flash. Like you should.
Besides, with Nandroid + titanium backups = not a big deal. You can always go back to where you were before flash or restore apps after.
Is there even a working TWRP for the N6P yet?!
With these new bootloaders, on a locked status, can you temp boot into an external recovery?
Re-locking your bootloader can be risky. If you're on a custom rom and rooted, if something goes wrong, and you can't boot into Android, you could be stuck in a loop and have to either re-flash the rom in recovery (hopefully custom recovery) or wipe and re-flash stock via fastboot. Alternatively, you could experience the same issues using a custom kernel on stock for root. Basically, with the new verity checks and security framework, at this point with the phone being so new, you're better off sticking with it locked or unlocked and keeping it that way for optimal use.
TWRP should add a password function.
It won't unlock features until you enter a password. This protects the phone even with an unlocked bootloader.

I agree that clean wipes are the way to go, but it wipes everything including pictures, media, anything you might want to flash. You have to move everything to a pc, and then move it back which can be a hassle.

This won't effectively do anything. TWRP is just the recovery component. As long as your bootloader is unlocked, a thief can just boot into the bootloader and overwrite your recovery with his own (a new TWRP without a password, CWM, stock, etc).

Nope. Why would someone store backups on the device they are backing up? That's just crazy talk. :silly:

There are a trwp skin that adds a simple password protection. but I have never proved it.

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

It just occured to me, that despite encrypting my device, I can boot into TWRP recovery and flash things to various partitions without entering a password.
Doesn't that essentially mean that the encryption key must be stored somewhere by TWRP in a clear (unencrypted) form?
If so, doesn't root basically render device encryption meaningless? Sure the average phone thief might not care to crack into it, but it would probably be trivial for anybody with a little technical knowledge and time on their hands. And police probably have a step-by-step process for cracking rooted devices.
Does root compromise encryption?

To answer your exact question, no, root doesn't compromise encryption. Root and TWRP are two separate things, you can have TWRP without root. However, TWRP does allow access to your data without requiring authorisation.

Thanks so much! This is exactly what I was looking for.
I don't know why it didn't occur to me earlier. I'm glad I don't have to choose between security and usability (root, TWRP, etc).
i was thinking about this today actually, because my phone has no encryption (both system and userdata).
However, with purenexus rom and cerberus if your phone is ON when it's stolen, you can essentially prevent someone from booting into recovery since the normal power menu is not available, and pressing and holding the power button for 10 secs just reboots the phone into OS again which is locked. Also, the USB defaults to charging, so data is inaccessible.
is there a way boot into recovery in a situation such as this?

They can hold Power and volume down to boot right into bootloader (and subsequently recovery) from lockscreen. I did this last night since restoring my TWRP 3.0 backup locked me out of my 5X lol

Keep in mind that when your data is encrypted and a boot password is used, they may can get into the bootloader, but they can not get inside your system. They will have to wipe it to get anything on it that will work.

Thanks for the clarification. Is there any way to get the boot password feature without encrypting my data?
As the title says, my phone just isn't unlocking, no matter what.
I know for a fact I'm using the right password, it's successfully decrypting my phone. Entering the same password or any password I've used doesn't unlock the right screen, though.
I tried flashing a backup from a couple days ago, but it's having the same problem too.
Any advice?
Did you remove all security from your devices before making a backup?
I've seen several posts that tell people to do so before backing up. So I think that's where the issue is.

If the backup you restored had a security pin still active then it won't restore properly or you won't be able to deactivate the pin code when asked for a screen pincode. At least that's how it has been in the past. They may of fixed it by now but that's only in the latest version.
This happened to me the other day when updating to the new PureNexus. There's a file in MM you can delete through TWRP so the OS will boot without a passcode, and then you can set a new one. I'm not sure whether I'm allowed to post it here as it seems dodgy but I found it in another XDA forum.

Go into TWRP>Advanced>File Manager>data>system.......delete locksettings.db, locksettings.db-shm, and locksettings.db-wal. Reboot the phone and you'll be able go into the OS just fine after that. You'll have to do this every time unless you make a backup with security removed.

You don't have the same BLOD because you have access to recovery mode. You have a functioning recovery and the guy in the video did not. Because you never unlocked your bootloader you are limited to side loading an OTA newer than the build you are on. When you enter recovery mode the current build is displayed at the top. Download a newer OTA from Google and follow the instructions on that page on how to side load OTA's from recovery.

Hi Guys,
I am Unrooted, Bootloader locked. Was messing with Substratum themes, finally messed something up where it's bootlooping.
Thanks to me getting out of the rooting business for a few years now, my ADB, Fastboot, and Safe Mode skills are blurry, at best. Plus this phone uses the same partition for Recovery and Boot?
Can somebody please hop on PM, here, or IM immediately to help me get out of this bootloop? I'd really appreciate it!
Thanks!

If you're locked on bootloader with no way to unlock it, and want a easy fix on your phone, unfortunately a factory reset is your best option but you will loose all your data. Just go to recovery mode and do a factory data reset.
Of course there's better options if you're willing to flash TWRP but remember to get your boot.img of your stock rom since yes recovery and boot are on the same particion.

Thanks bud. I logically came to the same conclusion and went through a factory reset ... On the off chance, I'd had my USB Debugging authorization saved, I might have had a shot to unlock the bootloader and flash TWRP while it was bootlooping, but alas, I did not save that authorization...
I wish they had more warnings in the Substratum Andromeda app for the non-rooted owners that this could happen, so make sure to not try things without at least a custom recovery ...
Thanks for all your help!
