Hey guys! Me again! Just wanted to know if you're supposed to wipe userdata for every custom kernel with this phone. I know it has the forced encryption and it complicates things a bit. I know if you flash an unencrypted kernel, it needs to be wiped because it can't read your old encrypted data, but as for a custom kernel change that maybe has encryption on, is a full wipe still needed? Thanks guys!

short answer, no.
long answer.. you NEVER have to wipe when flashing a kernel. what does your data and installed apps have to do with kernels? its like wiping your butt specifically to eat a banana :silly:
Oh no way? I heard the unencrypted kernels need a full wipe! And the same when installing the stock kernel back! Is this wrong info?
As for what it has to do with kernels, I thought it did just because this device specifically complicates it with it's forced encryption.

@simms22 banana huh. Lol I agree guys, and why would the encryption matter. Correct me if I'm wrong Simms but that's like saying yes to permissive boot, no to enforcing. Just kernel commands. Still a kernel. Fastboot wouldn't, flashifly wouldn't.

It's always best practice to to wipe or format userdata and if you have one when going from one version of Android to another (such as Lollipop to Marshmallow) but I guess there's nothing wrong with trying a "dirty upgrade" (no format) and seeing if everything works okay. If it doesn't you can always go back and wipe or format userdata and restore from your backup.

its made into a kernel option nowadays, but it really can be implemented by anything. it use to be apps that people used, but google banned all those apps from the play store, like 6 months ago i think.
Oh yeah I deal with selinux in repos. I just add the cmdline, but I was just using that as an analogy referring to encryption on kernel. Not seeing why encryption status would matter. @simms22

to unencrypt, you not only have to flash the kernel, but you have to format your storage as well. that completely delete everything. thats a one time deal though. those kernels actually give you an option, you can stay encrypted or you could decrypt. if you flash other custom kerneks, theyll give you the same option. from that point on, you could just flash. or flash your rom , and kernel. but you you flash a kernel that doesnt give you that option, itll encrypt you again.

i thought you were asking about it :angel:
When you mentioned app, I was lost. Google's encrypting apps. Guess I should a role a fruit rectum combo. Its a fine line simms. You can flash unencrypted w/o wiping or anything. But you'll still be encrypted until you "fastboot format user data.img". I decrypted twice first on fastboot, then tried the twrp format and it worked.

Alright, so basically you have to wipe when you first install an unencrypted kernel, but you don't have to wipe again when installing the stock encrypted kernel? This post is going so many random ways, from butt wiping to getting your daily intake of vitamins hahahaha

Once your unencrypted your good. No erasing data. I only did it twice because I needed to check a feature on cm as were cm based and they still had boot encryption. Should of known better. 1 time format data and install any kernel thats not force encryption

you need to format your userdata to decrypt, after flashing a kernel that allows it. you can use fastboot to do it, fastboot format user data.img. or you can do it with twrp recovery. it will delete everything in your storage.
Thanks everyone! You guys are awesome!
EDIT: This may be a stupid question, but you can't be too damn careful with kernels haha anyways, are custom kernels at all specific to a certain build? Or is it cool to flash a custom kernel without worrying about the build too much? And worst case scenario, you can just fastboot flash the stock if it just doesn't work?

Build meaning Roms correlated Android version. Yes they are specific. For ex an easy one is ElementalX , his site will list device- and version . kernel for 5.1.1 kernel for 6.0 and such. Visit his xda under original android development. You'll see how it works version wise.

It' s all about Android version. Generally, you should only use a 5.0 kernel on a 5.0 build, or a 5.1 kernel on 5.1, however, there aren't many kernel changes between 5.1.1 and 6.0, so you can actually use a 6.0 kernel without any issues on 5.11 - though you shouldn't go backwards and use a 5.1.1 kernel on 6.0
Per Android version yea, I figured. But they aren't specific as to like, only works with MRA48k or only works with LMY48I or something? And worst case scenario, can a kernel leave your device in a hard brick if it's at least for your device?

I am of the opinion that if you own a Nexus, you should root it.. it's too easy and development is awesome.
You could go back to 100% stock, yes. No on would ever be able to tell. You can do that in Wug's Toolkit.
You can undo a soft brick, hard bricks are hard to do on a Nexus.. don't do things you don't understand in Fastboot and you shouldn't hard brick. I dunno about undoing one of those, though.
You can't install OTA, but you can use Wug's toolkit or Fastboot to flash stock updates if you wish to go stock. If not, custom ROMs are updated to match whatever base (OTA) Google is currently using, so you would never be unable to update like on a locked phone like a Samsung because of root.
If you use the Kit, you should unlock your device, decrypt if you want to, if not no need, and install custom recovery with root, simple. It's very easy to do in Fastboot, though, and I would encourage you to learn.

No, it wouldn't even be possible to do it that way. You read exactly wrong, it's basically the opposite. You want to decrypt as soon as you unlock. Decrypting your phone formats your userdata, internal sd card at all, meaning it erases EVERYTHING on your phone. If you wish to decrypt, you want to do it after unlocking and before rooting and you always want to make sure to check if a ROM forces encryption before flashing it.. if you flash a ROM that forces encryption when you're decrypted it'll encrypt all your data. If you want to flash a ROM that forces encryption, make sure to flash it with a kernel that does not force encryption to remain unencrypted, Personally I just remain encrypted, easier and no performance difference Ive noticed, just read/write speeds and that has zero effect on use.

Is CyanogenMod decrypted?
No, Cm forces encryption. If you want to remain decrypted on official CM nightlies you'll need to make sure you're flashing them with a custom kernel that does not force encryption. I recommend Franco personally but many kernels will work for that purpose.

Guys I just have a question,
I will be receiving my nexus 6 tomorrow and I plan on unlocking the boot loader and rooting it, but what I am curious about from reading all the threads is a few things.
1) I plan on using adb to unlock boot loader and root
2) I plan on using flashify to install twrp so i can be able to get a backup of the stock recovery
My question is this. I plan on installing cm12 on my device and i like the idea of having my device descrpyted. I am told I have to flash the script I believe made by chainfire, but i also read u can flash another kernel. Which would i have to do? I read some say that u have to do the one made by chainfire first, and others said u just have to flash another kernel.
Also since the cm12 comes encrypted as default and lets say I "dont" want to descrypt do I have to before I flash cm12 even though its set as default encrpyted just like stock?

1) You'll need to use fastboot to unlock the bootloader. YOu'll then need to use fastboot to flash the recovery. If you're going to flash a rom, you may not need to then root as some roms are already rooted
2) flashify needs root to flash the recovery and you need the recovery to flash root.
What chain fire thing? Chain fire doesn't have anything in relation to encryption from what I know. Go to Android development and find the unencrypt thread and from there you'll find out how to unencrypt.
Do note that your data will be wiped. You'll have to flash a custom kernel before your phone starts up otherwise your phone will be encrypted again.
Most custom kernels have encryption patches to accelerate the encryption i/o speeds. You're better off just leaving it enabled if you want to keep things simple.

If i remember from previous devices doesnt flashify allow backup of the stock recovery? and also it flashes twrp within the app as long as root is done.
Edit:
Also I wasnt sure who made the descrypt file to flash, and yes i know it does a FDR, but wouldnt it be better just to flash a custom kernel? Most kernels are already descrypted. Sorry if i repeated anything.

That gives me root via fastboot up to the end of obtaining root and not doing custom recovery.
Within flashify i know u can back up the stock recovery, and then flash twrp. After i flash twrp i will be making a back up of my system just in case something goes wrong.
That sound correct? I prolly will give a few days and wait till my usb otg sd adapter to get here before i actually flash a rom. Sorry should have mentioned that.

fastboot unlock
run script
boot into android
install flashify
flash recovery
Download rom

fastboot unlock
fastboot flash recovery
put rom on sdcard
flash rom
It doesnt matter if you backup your stock recovery, because its all available on the google site anyway as this is a nexus device.

Do some reading off XDA on what encryption is and its advantages/disadvantages.
To be simplistic,
Encryption pro: more protection with your data
Encryption disadvantage: slower I/O speed
(Most custom kernels include patches that accelerate the speed of I/O with encryption on, Google's stock kernel does not include this)
Decryption pro: faster I/O speeds, possible increase in battery life as your phone is not using clock cycles to perform encryption (not by much, if any)
Decrypton disadvantage: less protection with your data, but if you're not carrying sensitive data, then who cares.
My suggestion to you is to leave it encrypted and if you don't notice anything slowing down then leave it. Keep it simple.

I recently received my nexus 6 a couple days ago and I LOVE it. The problem I am having at the moment is that I can't seem to get it to go decrypt. I downloaded the tool kit and my devices build isn't present. As a result, the tool kit it won't allow me to run the decrypt option on the fastboot window.
It's anyone running into this. My build is a LNX***.
First, what toolkit are you talking about?
Second, to decrypt the N6 you need to flash a modified boot image and then wipe your phone.
Thirdly, what's build LNX***?

You just need a custom kernel and a wipe.
another prime example of why you shouldn't use toolkits, if you don't understand what they are doing you shouldn't be using them.
To decrypt all you need to do is:
Backup your internal storage to a PC
Either use custom recovery to wipe everything including internal storage, install your rom and install a kernel that doesn't force
or
factory reset your phone, but before it boots up go back into recovery and flash a custom kernel that doesn't enforce

Although you're right, it is a personal ideal of many of us, I don't think he intended to come off as a jerk. But his point is that toolkits often remove the need for knowledge, which can become a problem for some users.
The good thing about nexus devices is that everything is pretty easy to do, so if you get stuck - continue to ask.
+1 to what rootSU said. And you should probably upgrade. That build is ancient and doesn't even have an official factory image (the reason it's not available in NRT).

Hello! So I just have some questions about the forced encryption on the Nexus 6. I will be getting a Nexus 6 very soon here, and I like custom ROMs and custom software. Questions are:
1) Can I install a custom ROM without even messing with the forced encryption? In other words, can I ignore that it's there and just unlock bootloader, install custm recovery, and flash a ROM and gapps? Will it just run with the encryption on?
2) If I do disable the encryption, can I use the normal software update? (with no custom ROM of course in this case) Or will I have to reflash the encrypted kernel to system update?
3) Do some custom ROMs just disable the encryption by default?
And
4) If it get stuck in a boot loop because of a kernel issue, is this easy fixable? Or is it a hard brick that can't be recovered?
Thanks in advance everyone!

1. Yes
2. You can't update with any modifications to the system. Meaning you must have stock recovery, no root, etc.
3. Yes (They don't FORCE encryption meaning if your unencrypted already you will stay unencrypted.)
4. Yes

Thanks for the quick response! Much appreciated. On my fourth question, did you mean that's easily fixable? Or like, yes that's a hard brick? And also, (question 3) you say that a custom ROM won't force it, but if you're still encrypted when you flash the ROM, does that mean you can just turn it off in your settings with a ROM? Or do you stay encrypted? Or how does that work?
EDIT: (question 2) if I used a toolkit to reflash a stock image, that's clean enough for a normal system update right? After that and relocking the bootloader?
Sorry for all the questions, I just wanna know these things before I go fork out $600 for a device that I intend to mod!

And also, (question 3) you say that a custom ROM won't force it, but if you're still encrypted when you flash the ROM, does that mean you can just turn it off in your settings with a ROM? Or do you stay encrypted? Or how does that work?
EDIT: (question 2) if I used a toolkit to reflash a stock image, that's clean enough for a normal system update right? After that and relocking the bootloader?
Sorry for all the questions, I just wanna know these things before I go fork out $600 for a device that I intend to mod!

To be unencrypted, you must format data. Do not use toolkits unless you know how to use ADB/fastboot. Yes this phone is hard to brick as long as the bootloader is unlocked.

Hello! So I just have some questions about the forced encryption on the Nexus 6. I will be getting a Nexus 6 very soon here, and I like custom ROMs and custom software. Questions are:
1) Can I install a custom ROM without even messing with the forced encryption? In other words, can I ignore that it's there and just unlock bootloader, install custm recovery, and flash a ROM and gapps? Will it just run with the encryption on?
2) If I do disable the encryption, can I use the normal software update? (with no custom ROM of course in this case) Or will I have to reflash the encrypted kernel to system update?
3) Do some custom ROMs just disable the encryption by default?
And
4) If it get stuck in a boot loop because of a kernel issue, is this easy fixable? Or is it a hard brick that can't be recovered?
Thanks in advance everyone!

3. its the kernel, not rom, that makes you be abke to decrypt, not rom. it might be added to a rom as well, but it would be in its kernel. also, ot doesnt decrypt, it gives you the option to decrypt. but you have to do it, decrypt.
4 easily fixable. you have to learn the very basics of it though. rrally. but its extremely easy to fix.

learn to do it right the first time. it sounds hard and complicated, but its extremely easy after you do it all manually the first time. after that, feel free to use a toolkit. it wont save you time btw, doing it right takes just 3-5 minutes after the first time
Thanks guys! Much appreciated! If things were to go horribly wrong with the kernel if I did decrypt it and it bricked because of a kernel issue, would flashing a stock image still be a fix for a kernel problem? (with the bootloader unlocked of course). I'm not new to Android modding, I have a phone running a CM nightly right now, but this encryption thing and messing with a phones kernel scares me a bit haha

Flashing any rom also flashes a kernel, so you've already done it before. Its no different here

every rom haa a kernel in it. a rom can not run without a kernel. a kernel is like what will connect the cpu and hardware with the os.

The first question you need to answer is:
'Why decrypting?'
When the answer contains words like 'speed' or 'performance' than you may consider to leave your N6 encrypted.

Well, I've heard from many sources that the encryption in the phone just KILLS battery life, and if you turn off the encryption, it nearly triples the battery life. Is this true? Because it would be a waste if the phones battery is abysmal for such a great device! From anyone's experience here, should I not worry about it and just leave the device encrypted?

I wouldn't say it triples battery, just increases the NAND read/write speed performance. Battery could take a hit as opening apps takes longer when encrypted.

Apps aren't encrypted. If they were we couldn't pull them from phone to decompile and mod them. Only your data is and it is only a few KBs per app. Only notice encryption on large personal files and downloads.

im encrypted, and my n6 sees between 5.5-7 hours sot. thats more than most unencrypted phones see!

battery life is all about how you personally use the device, how you set it up, which apps you use, and your phone/data signal quality. everything else plays a minor role for battery.
Alright! So if I just ignore the encryption and install a ROM, it won't pose a problem at all? I can say, leave it encrypted and install a cm ROM without issue? And because of the encryption, do operations like installing a zip and formatting the device take a lot longer? I'm using a Galaxy Note 2 right now and the ROM installations take mere seconds to install, so a Nexus 6 might be something different.

formatting is how you decrypt. besides decrypting, theres no need to ever format your device. installing a zip it depends on the zip, generally its fast. flashing a zip is fast. what will be slowed down is tranafering a large file to your computer to or from a pc.
oh, and cm does get many bugs, often.
Oh yea! Bugs for sure! I'm running a cm nightly right now on my Note 2 and it's buggy as hell haha I just like messing with ROMs really, I will probably leave it stock and rooted for the most part Just like to see new ROMs and tweaks and stuff. Thanks guys! You all helped a ton! I will probably buy a Nexus 6!

I have tried decryption with the Chroma and CM Roms. I did not notice more performance in daily use.
Then 5.1.1 arrives with some confusion because Google presented several factory images for the N6. I went back to stock and waited for the OTA.
After flashing the OTA and Franco's kernel my battery life was about the same.
Of course it depends on the daily use, but for me it was clear that not decrypting causes better battery life but the kernel.
so, just got my nexus a couple of days ago, and loving it!
would like to decrypt, but not 100% sure on the best/safest way to do it at this point..
running pure rom, with lots of tweaks, and I originally unlocked and rooted with Wugs great toolkit.
I know if I decrypt at this point I will lose all my data and stuff, but of course its already backed up in a couple of places, and I have the "fixes" to flash after I decrypt to keep me that way, if I flash a "encrypted" rom by mistake.
Just wondering if someone could make a straightforward post, telling me the 3 or 4 things I need to do/flash to get to that point.
Thanks so much!:good:
you need to flash a custom kernel that allows for decryption, then you have to format your storage. only then will you boot up decrypted. if you dont actively decrypt(format your storage), you wont be decrypted. this will delete everything in your storage.
ok, then do you know of a kernel for Tmobile that allows for that?
do I flash that kernel in twrp, then also format everything else in TWRP?
if I do that, how do I then boot my phone into something useable so I can rebuild it once again?
thanks

You can use the Nexus Root Toolkit to decrypt as well. I believe its under advanced utilities-flash boot image. You will have to be on a stock build however, so you could also use flash stock plus unroot. I believe there is an option there for flashing a no encrypt kernel in the process.

any custom kernel does. and there is no such thing on any nexus device as aa rom or kernel for a specific carrier, they all work on tmobile.

Final question; is there a REAL difference in performace when you are decrypted, or is it mostly placebo?
this phone, on Pure Rom, is super fast and smooth, and I cant imagine it getting much better if decrypted, but as a Nexus N00b, I just dont know.
Thanks again for your help and feedback :good:
Most likely Pure has a decrypt kernel. Haven't looked. Beans usually adds all those tweaks. Just need to format data. May Lose your data and have to start over. Not sure as I run encrypted. If run decrypted might as well welcome Stagefright too.
ah, good point, so running decrypted makes you vulnerable to that krap...

Decrypted makes you vulnerable to any data exploit. Stagefright is different but both are security risks. Probably won't see a performance boost with decrypt. Only can be seen with large data files. Won't see with apps or daily use.

I've ran both. And I actually just decrypted for a second time to see if I noticed any difference. To be perfectly honest, and this is just my personal experience, I haven't seen any noticeable difference between being encrypted or not since the release of 5.1. And since there are some ROMs out there that do have force encryption, I personally am going to go back to being encrypted just so I have one less thing to worry about when flashing ROMs. But there is a flashable zip that you can flash after any ROM that will disable force encryption if you want to go that route.

Let's clear things up. There is only one way to do it. You first need a kernel that doesn't force encryption (most don't force) so check the rom thread as its kernel probably doesn't either.
Then, you have to format userdata, which means all your apps, data (including sdcard) and settings will be gone.
Granted, there are a few ways to get these 2 steps done, but "fastboot format userdata" or format /data from TWRP recovery are the best.
As for TMobile, its the exact same phone as every other in north America, so all roms and kernels work. Actually there is.only one other model.(international) .and that works.with all the same.ROMs.and kernels.too.
Thanks for clarification. The format userdata was what I wasn't sure about. Recovery format I know clears all data. Fastboot format userdata restores data after format. Fastboot erase userdata wipes data. Wasn't sure which type format was required.

thanks man, I am out of thanks for the day, but I do appreciate the input!
it sounds like with 5.1, there isn't a real strong reason to decrypt, and with all the stagefright nonsense floating around, and what ever other hidden exploits there are, its probably better at this point to just stay encrypted, since it doesn't sound like there are any major advantages to decrypt right now.
I appreciate everyone who posted in here for their knowledge and insight, and I will make sure I help anyone else going forward with a similar question.:good::good:

fastboot erase userdata wipes all data but doesn't recreate the file system so the filesystem will retain the encryption flag.
fastboot format userdata will recreate the filesystem losing the encryption flag and since the kernel won't re-add the flag on boot, ,you're good to go.
Neither restore data.
Same in recovery, erase/wipe data won't format, only format will.

You are correct. Thanks for the clarification. I run modified stock rooted so don't run into a lot of these scenarios that break their devices. All my mods are hard coded.
