[ROM][3/26/15] Pure AOSP ROM -★| 5.1.0_R3 | LMY47I | Build #6 | Proof of concept! |★-
Pure AOSP for the Nexus 6​
Preface:
This is meant to be a Pure AOSP build with just minor edits to stop the stock recovery from replacing custom recovery, add some Google edits to the ROM for GPS, and modify the ramdisk so as not to preclude it from being rooted! Its not meant to be a fancy ROM, its just meant to be a baseline AOSP ROM. This ROM was produced by following the steps in the build guide I wrote. See post #2 for build guide links!
Install Instructions
Must have custom Recovery on unlocked device
Copy ROM to device (Gapps and root too!)
Reboot to recovery
Choose Factory reset (TWRP, not sure what CWM is)
Choose Install ROM
Now you can install the Gapps, and Root if you desire!

Want to build this exact ROM yourself?
Here is a great build guide I wrote: [Guide][1/19/2015] Building AOSP for the Nexus 6!​

Hmm... I'll take this for a spin later. Thanks!

Is it safe to say with this being pure aosp shamu that it is still set to force encryption?
Also, the drawback of not doing the block style flashable is it takes several times longer to actually install via recovery.

Yes. Its pure AOSP.
Can you give me a calculation of time to install block based and file based ROM? Several times longer is a strong statement. If you could produce factual data I would appreciate.
However I am still not going block based installs because the user can take this ROM, add or remove things before it is even installed.
But I look forward to the numbers you show me! If you dont have the data that is fine. I can change the false to try in the script ota_from_tools and test it myself. Should only take a few minutes to recompile as block based.
But thanks for the input!

Took like 3-5 minutes to install your ROM and maybe 20 seconds to at most a minute to install either rastapop or cm12alpha. Honestly I thought it stalled or failed so I rebooted recovery and installed just your ROM (instead of gapps together via twrps) and it simply takes a LONG time to flash.

Great to finally see you here scrosler!!! Always great to welcome another knowledgeable developer to the forums

The exact numbers your reported time can vary buy almost 66%! Thats a huge variance.
Also, you are testing differnt ROMS. For a control I need to build this exactly as it is but block based.
I will test it on my device with a high end chronograph and report my results.
Also, what recovery are you using?

---

Ok, I timed the file based intall, it was 2:16.08 (which was closer to your 3 minute estimate but a far cry from the 5 minute estimate)
I will build a block based ROM tonight and test to see the difference. However its still very unlikely I would change the current set up. Although I could just post both! :highfive: Win Win for everyone :good:
But once again! Thanks for your input!

I can time it if that helps, or you can test yourself if you would rather. As for recovery, the only one I know of is twrp, downloaded directly via their website (only one version there) and manually fastbooted in place.

We are cross posting. I timed it myself and it was just a hare over 2.25 Minutes. Which is not that far off from your assert of 3.0 minutes.
Im going to build the block based tonight and post it so people can have both options.
You brought a valid point. Once again, thanks for your input!
Edit: Also, wasnt trying to beat you up, I just like solid number comparisons.

Haha no worries, us old optimus s veterans need to stick together ?
Edit: if you wanted to remove the force encryption, it is a very simple fstab.shamu edit. Under the /userdata line, change "forceencrypt" to "encryptable". Looking at a few rom sources, that is how they all do it. That way if you are encrypted you will stay encrypted. If not, then it wont force encrypt you. Would save people from having to flash an alternate kernel . .

OMG!!! Optimus S? Are you serious? That was my first Android Phone / ROM!
Yeah, I know how to shut it off. But i wanted to leave this as close to pure AOSP as I could. I think I will shut it off on the next build though. I heard the encryption can slow things down a hair too.

---

Ok, I just got lost reading comments. Is this encrypted? If it is, does anyone mind letting me know what to do BEFORE I flash to decrypt.

You just flash a no force encrypted kernel which I basically any of them. And as @scrosler just said he may just build it into the next build.

And yes, same user name over at android central, I had DanteRom that I released. ?

EDIT:
DAMN! There is no comparison from Block Build and File based build
Block build was roughly 2 minutes and 30'ish seconds
Block based build was 10'ish seconds!

Hey Scott glad you are building for the nexus 6 are you planing on a Clean Rom also? Or just keeping it aosp

I'd say leave it encrypted for now until faux finally makes it to the threads...from his g+ posts it seems his found a way to keep the device encrypted yet have around the speed as though it was unencrypted. And he's a very open source guy so I'm sure he'll share the magic
