[Nexus 6 Q&A, Help & Troubleshooting] scryan:
Unlocking the bootloader really only allows you to flash unsigned images, and root provides you with the option to grant administrative access to applications.

Neither one of those has anything to do with encrypted data, or in any way makes encrypted data readable without the key.

The bootloader unlock will make it easier for a thief to wipe all the data on the device without reading it, so he can use the device or sell it as functioning... Even then, you may be able to factory reset an encrypted device without the key anyways... At which point I would think they could make a new key for the freshly wiped partition?

Anything that is going to run unauthorised code at root level is likely going to use other exploits to achieve root on their own, like users do to gain root on devices that are locked down. You having root access doesn't give the right for anything to run as root unless you approve it (or if someone managed to find some exploit in the version of supersu your running, but this is not likely... and if we are assuming any code may have holes in it you're not safe no matter what you do). It does give you the possibility of being tricked into running malicious code that is disguised as some utility... But that is a risk your going to take running any software that isn't from a stable corperation you can take legal action against. Trust who wrote the code or don't use it.

If in question number 1 "the security feature" is encryption, then yes having and unlocked bootloader means if someone takes your phone they can flash a kernel that does not force encryption, they would then have to format the userdata partition to encrypt the phone. Without luck, guessing the password, or discovering some amazing undocumented flaw in the encryption algorithm they will not being able to read your data with out having the key, or guessing it.

If you have unlocked the bootloader and have installed a custom recovery (TWRP), are you able to see the list of files in the file manager of TWRP, if the device is encrypted?
[Nexus 6 Q&A, Help & Troubleshooting] prdog1:
Yes. Otherwise couldn't pick a file to flash. It actually only encrypts user data. Apps, zips ect are not encrypted or we couldn't pull and modify them. :cool:
[Nexus 6 Q&A, Help & Troubleshooting] Nikos2k:
the user data that are encrypted include files on the sdcard folder? (e.g. pdfs, images in DCIM folder etc)

i am asking because in my device in Settings -> Security -> Encryption it shows that it is encrypted, in TWRP however i can see all the files

Can i make the custom recovery to ask for the pin? do I have to enable PIN as a screen lock?

What happens if i use an unlock pattern or just swipe for unlock?
[Nexus 6 Q&A, Help & Troubleshooting] prdog1:
TWRP will use same pin as Device lock. Only thing I have seen if you use pinlock have to convert 5x5 to 4x4. There's a way to convert it located in this forum somewhere. Swipe to unlock has no pin so TWRP is open. Unlock pattern works also. Either pin or swipe has to be converted don't remember which. I run wide open encrypted so have never played with it. :cool:
[Nexus 6 Q&A, Help & Troubleshooting] Nikos2k:
By pinlock you mean the pattern screen lock?

I think it is 3 x 3, not 4x4 or 5x5

And since I use this pattern screen lock, which cannot be input in TWRP, this means that I have to disable it b4 I need to enter recovery?

This makes me a bit uncomfortable since I may need to enter recovery because of a problem with the system

thank you it worked!
[Nexus 6 Q&A, Help & Troubleshooting] quickdry21:
Ok, so for encryption, "Allow OEM Unlocking" allows flashing of unsigned images (such as the one used for root), which means if someone gets a hold of my phone, they can put whatever they want on it, including flashing a custom rom.

So my next question is, what about being required to sign into the last Google account used on the phone even after a factory reset (device protection / factory reset protection / not sure what it's called exactly)? Is that area of the bootloader / rom / memory / wherever it lives flashable? If you have an unlocked bootloader, is it possible to flash some image to the device that disables this? Hah, that sounds bad. Really, I want to root my Nexus 6, but I haven't decided if it would be worth giving up the anti-theft required login after reset.

I guess really, I'm curious about how it works, is it part of the Android image delivered by Google? Is it part of the bootloader? Is it possible to release a rom without this feature? I'm not a thief, I swear I'm just curious. ;)

[Nexus 6 Q&A, Help & Troubleshooting] simms22:
protection will be gone if you flash android 5.0.1. if you wipe and flash android 5.1.1, the protection will still be there and will ask for your password first.
[Nexus 6 Q&A, Help & Troubleshooting] quickdry21:
Thanks, that does seem to make sense.

I know this comes across as overly paranoid, but I ask also because I'm a curious developer. I'm interested in understanding how android's insides work in general as well as how the new device protection fits in with rooting, custom roms, unlocking the bootloader, etc. (just how well does it prevent unauthorized use of devices)
[Nexus 6 Q&A, Help & Troubleshooting] quickdry21:
Interesting, that says to me there is a relatively easy way to get around the reset protection if a phone has an unlocked bootloader. Albeit, relatively easy is relative.
[Nexus 6 Q&A, Help & Troubleshooting] simms22:
easy, yes, for one of us. but for a typical user, very hard. anyways, i dont like letting out the secret of how to bypass it, so keep it quiet please :)
[Nexus 6 Q&A, Help & Troubleshooting] quickdry21:
Yes, agreed. I'm going to edit out that quote.
[Nexus 6 Q&A, Help & Troubleshooting] scryan:
Maybe someone could figure out something?

But if your device is wiped, and basically all the partitions are re-written.... Where do you want to store the last google account information to check against?

No one is going to plan on stealing your phone, ask you if the bootloader is unlocked, then decide not to if they say no. None of the security really prevents your phone from being stolen. Nothing just looking at your phone lets a would be thief know that its encrypted and not unlocked...

The encryption and locked bootloader will not prevent your phone from being stolen. The encryption will protect your data, and the locked booloader will make it harder to reset the device (though does factory recovery have a factory reset option? I would think this would allow the device to be wiped and encryption key to be reset anyways?)

What? You keep talking about this single security device? What are you talking about?

Do you mean encryption?

encryption is just how the data is stored on the device.

Say you have the word "Duck"

And we want to store that word in a safe way. As a VERY VERY basic method, we will encrypt this by shifting each letter of the alphabet a certain number of letters. This number will be something YOU give, so that others do not know how many letters we have shifted over.

So lets say you give us "5" as your key.

so the alphabet

abcdefghijklmnopqrstuvwxyz we will shift 5 letters over, starting on the fifth letter and wrapping around...

fghijklmnopqrstuvwxyzabcde so each letter matches up with a new letter.

D is the 4th letter of the alphabet, so we will use the 4th letter of of shifted alphabet, i

u is the 21st letter of the alphabet so we will use the 21st letter of our shifted alphabet, z

ect, ect... so Duck becomes Izho, and with out knowing how many letters to shift over, know one will know what that means (ok, obviously due to the simplicity of our encryption algorithm, anyone who is smart and cares can likely try different numbers until the output is a coherent word. the actual method of encryption is significantly more complex, and the key is more then one characters

na, it ok, you can leave it here. that way if someone really needs to, theyll find the answer here. just dont go around spreading it around i meant :)
[Nexus 6 Q&A, Help & Troubleshooting] quickdry21:
I'm not expecting this "Device Protection" feature to prevent my phone from being stolen, I'm more interested in the **** you aspect to someone who tries, and maybe them returning it to me for some money.

I'm not sure if you are aware, but with the release of 5.1, there is a new security feature (think it's called Device Protection, but that seems to encompass some other things) that requires you to login to the last Google account attached to the phone after a factory reset (whether done from the settings UI, or from recovery mode). If you are unable to login to a Google account that was attached to the phone, the phone becomes worthless (there have been some posts on xda about people "acquiring" a Nexus 6 and being unable to use it), some details here: https://support.google.com/nexus/answer/6172890

A quote from that link sums it up:

Now, this security feature is only available on new phones that are released with 5.1 (with the exception of the newest round of Nexus devices, which received it with the update to 5.1). This leads me to believe that some aspect is baked into the device. Separate encrypted partition maybe? Part of the bootloader software? I don't know, that's what I'm curious about.

Yes, I was not very clear in my original post about what security feature I was inquiring about. I'm aware of what encryption is. Part of the reason I am interested in rooting my phone is to reverse tunnel a SSH server on the phone, or possibly netcat, via SSH to my server, so I will be able to open up a shell on my phone from anywhere I desire.
[Nexus 6 Q&A, Help & Troubleshooting] scryan:
Ahh yes, apologies, was unaware they implemented that feature. A bit dense this morning.

I would imagine unlocked bootloader/custom recovery would DEFINITELY negate this feature.

No one gonna give your phone back, particularly after you use this as a "**** you" :P While its just IMO, its better to enjoy your phone now. Screwing yourself out of features only to attempt to limit the phone once you don't have anything to do with it anymore does not seem to be particularly productive.

I'm reading about issues with Sprint activation on phones purchased from Amazon and Best Buy. Is this everyone, or just a percentage of those MXPE owners?

Who has successfully activated on Sprint AND received the proper SIM from them? If you did, exactly how did you do it?

Who has not been able to activate?

Thank you!
[X Style (Pure) Q&A, Help & Troubleshooting] mark.maatman:
I was able to activate on sprint. They had to leave off the last number in the IMEI to get their system to accept. Then they added a SIM card and everything was good to go. I don't know the details of what SIM card they had to use. My phone came from Amazon.

here is a pic of the sim ...

Here in Augusta a very knowledgeable rep gave me this for free.

But I ordered from moto so the 15th it is for me.

She also said that once more Moto X's were activated the easier the process would be.

In essence Sprint learns by trial and error..

Oh and sprints sim card seem to be device specific.Unlike Verizon and others.

I was thinking cut my Note 3 sim to Nano size and Vaaaala...

But she said that would not have worked. ..

I got a 128 gb sd and clear case and glass shield waiting..

[X Style (Pure) Q&A, Help & Troubleshooting] Xpalidotious:
Interesting. In anticipation of getting my MXPE from Amazon tomorrow, I went into a Sprint store in Aliso Viejo last week and inquired about activation. The rep told me that I could not just take the SIM out of my Moto X 2013 because it doesn't work with SPARK and the new MXPE does, so it takes a different SIM. He was about to just give me the SIM when his coworker said that I had to have the phone in hand before they would give me the SIM.

That said, I'm just trying to get my ducks in a row for tomorrow morning when I open my phone. I would like to not have any surprise issues. I'm thinking I'll try to activate it myself online using the leave the last number off the imei technique and then head over to a Sprint store for the SIM. Anyone have any thoughts on that strategy?
[X Style (Pure) Q&A, Help & Troubleshooting] ttkyles:
It's amazing how I hear stories about various sprint stores. I mean you can drive 10 miles and get a totally different experience with customer service reps.

Some are geeks and know exactly what your talking about ,then others don't have a clue.

I find that getting familiar with a sharp rep at a store is invaluable. I mean I go to the same rep,who roots ,knows about xda,and if I do surprise her with something,she quickly researches to give a solid answer.

Same thing with phone support,I've practically hung up on some ,called back to another with better knowledge.

You would think cell phone providers would train their staff or at least one advance rep to talk the xda/geek talk that the average customer would not mention.

[Galaxy Tab S2 Q&A, Help & Troubleshooting] Tubgirl:
Hello

I've got a rooted SM-T715 and I'm trying to find a solution how to either change the colour of the statusbar or completely hide it because I've had screen burn-in on all my AMOLED devices so far (Galaxy S2, Galaxy Note 1, Galaxy Note 2) and the place where it shows the most is always the statusbar. Since the statusbar is often black it doesn't wear as much as the rest of the screen and after a year or so that area will be brighter than the rest of the screen and is visible when you use it in landscape mode.

Brgds... /Tubgirl
[Galaxy Tab S2 Q&A, Help & Troubleshooting] ashyx:
Use a 3rd party launcher that allows you to hide the status bar.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] Tubgirl:
Thanks, but I believe that will only hide the status bar while on the "desktop". Once you start up an app like Facebook for instance the black status bar will be there again.

Brgds... /Tubgirl
[Galaxy Tab S2 Q&A, Help & Troubleshooting] Brittany_Menton:
Since the display is 16:10, you are unlikely to notice any screen burn in as most videos will letterbox at the top. Most of the time that status bar is always visible in all apps, and the ones that hide it are usually videos which mostly are 16:9.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] 3DSammy:
I have two apps that can hide the status bar. Nova launcher only hides the status bar on the home screen as you said but GMD Gesture Control has an auto hide action which works on all screens. I use GMD for immersion mode plus many other gestures plus launcher pop-ups which also work no matter which app is displaying.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] Tubgirl:
Thank you Sammy... this was EXACTLY what I was looking for!!

I purchased GMD Gesture Control and now with a simple gesture inside any app I can toggle the statusbar on/off.

[G4 Q&A, Help & Troubleshooting] zkyevolved:
Hello everyone. I have the G4, and I just refreshed it yesterday - so I have very few apps. I downloaded the kdz from a pinned thread here, even though it said it was D, it flashed B or C. But it's OK, it updated to D all on its own.

Anyways, I opened an app and it said I had 500 mb free of RAM, which is fine. But I said "Hmm, I wonder, on a fresh install, what's eating my RAM?" so I went into the Apps in the settings and it said I have more than half my RAM free (1.5gb or so). Here is a screen shot. So then I downloaded another app and it reported the same thing, only 500mb free... I'm very confused.
[G4 Q&A, Help & Troubleshooting] Pfeffernuss:
A. Unused Ram = useless Ram. The more is being used the better (faster) the phone will be/react while using/opening apps.

B. Don't use Ram managers

:good:
[G4 Q&A, Help & Troubleshooting] zkyevolved:
Hi, thanks for the reply. But I wasn't complaining about it being used or unused. I'm asking about why my system reports one number, while an app (ram manager or not) reports another. As I mentioned in the OP, I was curious about what I had installed that could be using so much ram that any app reports, but the system doesn't. It's a discrepancy. Not a complaint. I'd just like to understand what's happening and which number is correct. :good:
[G4 Q&A, Help & Troubleshooting] Pfeffernuss:
Don't forget that a lot of memory is also being used for cache. This is something the stock Settings apps doesn't display when opening it.

See for an example in the first image my current memory usage using the stock Settings app, it's stated that approximately 900MB of memory is "free". When using a system tool this would probably result in a different, much lower, number.

That is because of the cached memory. Press the three dots in the upper right and let it also show the cached memory. And presto, there it is, a more "accurate" display of all the memory being used. The value shown now should reflect the aftermarket system tools memory usage as well :good:
[G4 Q&A, Help & Troubleshooting] One Twelve:
It means about 1 gb of apps are setup as cached on fresh install. If you clear them you will get your 1gb RAM back.

There is no reason to do it! Ram is there to be used. I just thought it strange to see on a fresh install with very few apps running to have that little free ram! Haha. Thanks guys! :D

So I had this SGP321 for over a year now.Bought it brand new from this guy on the internet for a suspicious low price.Not a real shop or anything so no waranty. It worked very well for a few months then I noticed it started rebooting every now and then.After a OS update that was rolling out at that time (can't remember the version) the reboots were more often.After the KitKat update arrived and I downloaded it,after the process was over and the phone had to reboot,it entered a reboot loop that could not be stoppped (apart from forced shut down,but with same thing when trying to turn back on). I repaired the OS with the PC tool,no changes.I flashed older versions of stock OS with flashtool,reboots every couple of minutes. Then I installed Cyanogenmod 11.That worked very well,no reboots,but had many bugs and battery draining fast in stand by (about 1% per hour no matter what I deactivated,or with various apps to induce deep sleep). The new CM12.1 does not work,keeps rebooting.

Now,yesterday I tried again and again to get the tablet to work with a stock ROM. I only intend to use it for reading comic books,so all I want is a stable ROM with good battery life.So I would like to have a stock one. But why does a custom one run fine on it and a stock one keeps rebooting? I tried Sony forum but they were at a complete loss and sent me here for help.Any ideas?

[Android Q&A, Help & Troubleshooting] es0tericcha0s:
It's not possible. VZW S3 with 4.3 and above updates have locked bootloaders. This means you can not install a traditional custom recovery and it does not allow flashing custom kernels, which anything non Samsung based would need. Your only option would be the Safestrap recovery and custom rom based off of Touchwiz. You can not downgrade either to an earlier version of the software before the bootloader lock either, just in case you had that idea. VZW asks Samsung to muck it up like that.
