[INFO]WARNING: Android 5.0 Bootloader and Kitkat Compatibility

Android 5.0 (Lollipop) Bootloader and KitKat Compatibility​
Everyone wants Lollipop, however it is worth considering some of the possible consequences of upgrading via OTA update.​
Bootloader:
A new Bootloader (BL) will almost certainly be included in the OTA update. It is also very likely no KitKat Kernel, stock or custom will be able to boot properly with the 5.0 BL. Perhaps the Kernel DEVs can find a workaround.
Root: (ETA: Unknown)
It may take some time to gain root access on Lolipop as on other devices this has required a custom Kernel. A custom kernel itself may require kernel sources to be released - something that has taken weeks / months in the past.
Xposed Framework:
Developer has said he will wait for CyanogenMod based on Lollipop before properly starting development of an ART version of Xposed. CM12 may take a few weeks to release. Expect to do without Xposed for at least a month, probably longer since root is also required (see above.)
Custom Recovery:
This has not been an issue before, but it is always possible a new Bootloader could break compatibility with existing Custom Recoveries. Obviously, you would not be able to restore a CWM / TWRP backup without a functional custom recovery; but even then, it is unlikely you will be able to boot your KitKat backup.
Custom ROMs:
This is another area that could be affected by a new Bootloader. It is unknown if existing custom ROMs will require new Kernels / system changes in order to work with the new BL - something that could take days, weeks or months.
Performance:
Currently the performance difference between KitKat and Lollipop is unknown. If the first release of Lollipop for Android One has performance issues, you may be unable to revert back to stock KitKat.​Possible solution:
Wait for a flashable zip [NOT OTA Update zip] of Stock Android One Lollipop ROM - this would mean your Bootloader remains at it's current version and potentially allowing you to change 'back and forth' between Stock KitKat and Stock Lollipop. However, it is currently unknown if the newer BL is a requirement for Android 5.0 Kernels.
This is taken from the Moto G thread and all credits goes to @lost101.The sole motive of this is to create awareness about the new bootloader included in 5.0

Thanks For The Info @DC07 :highfive:

Thanks For The Information Bruda !!

This thing is only for device like motorola, samsung etc.. As I never saw same thing for nexus.. Motorola does not allow to downgrade so they update bootloader in every android version update.. I dont think it will be same for sprout

Let it arrive ,no point in discussions on thongs that are not confirmed

Nope. The bootloader was updated on my nexus 7 flo for the 4.4.2 OTA. Since this update is much bigger I think we'll have a bootloader update too.

doubts about lollipop arise

Lollipop on n900a?

Hello,
I have been searching and looking. Is there a way to get the lollipop on a n900a? If so, what needs to be done? I don't think it's as simple as flashing the Cyanogenmod12 on a rooted 4.4.4. Any links or ideas how to get this to work?
Thanks in advance.

no. not until att releases an update.

How about using a safestrap?

nope. we need a leak or official release that has a kernel for lollipop.

Did you have to downgrade back to 4.4.2 and then upgrade to 4.4.4 with the stock kernel just curious. I seen that you were running a rooted 4.4.4?

There's a leak already here on xda, not yet for us, I wish somebody would make it work for us . http://forum.xda-developers.com/galaxy-note-3/general/guide-t2983873
RoloRacer on KillerKat Note 3

So disappointed that AT&T are dragging there feet on releasing Lollipop 5.0
Wish we could find a version out there for SM900A

Still looking for a complete guide to getting on a working version of 5.0+ rooted, xposed sm-900A... even if it requires Odin's great wrath.

Behold... It Works...

The only issue I'm having is the mic... other than that, I've got it rooted although SS won't work on this version... supposedly.
Enjoy.

[Q] Moto X Pure Edition Rooted on 4.4.4 update to 5.0

Hey Guys!
So i am on a rooted pure edition 4.4.4 Moto X Pure Edition (XT1095).
I do get the OTA update for 5.0 but I have not downloaded it because I have rooted the phone. So my question is , can I do a complete unroot using SuperSu and then continue with the OTA?
Is that safe? If not , what is the best way to get to 5.0
Thanks

Should work just fine from 4.4.4 to 5.x It did on my 2013 Nexus 7 which was stock rooted + unlocked bootloader. The only thing I ever had to do was re-root after and you'll have to do the same. The same root method and file works on 5.0.........I just used it a couple weeks ago on my X which was on 5.0 out of the box because I just got it.
Once you're on 5.0 though it's more work to get updates. Google changed what they're looking for when checking the partitions (can't remember exactly what offhand) and now if any modifications have been made (rooted, added/removed system apps, etc.) the OTA's will fail. On my N7 I had to wait for the factory image to be released and I just flashed the system.img in fastboot. I'm not sure what will be needed on the X since the only images I see so far are for 4.4.4

which ROM are you using???
marshmallow on sprint HTC one M7??

Hey I am running marshmallow now on my M7. I got the rom from http://www.vanir.co/word/
What you have to do is download the latest lolipop rom first - then when that rom is installed there is a ota for the marshmallow rom. Its cm based and works pretty good. I have rooted it and am running xposed. The root for this rom is cool because you just go to developer options and turn on root access. No need to install SU as a separate app. Also, the ota is great. This may be the best rom I have installed yet to date.

You can find the latest version of Marshmallow here, http://www.emccann.net/nuclearmistake/VanirAOSPNightlies/m7spr/

Is it still required to first install Lilipop ROM instead of just installing the Marshmallow ROM right off the bat? I'd prefer to go straight to Marshmallow as is done in the video: https://www.youtube.com/watch?v=6gyLF02rgFY

Their latest nightly will stand alone. Just install has you would any new rom. Be sure to use their gapps.

Nougat to marshmallow custom ROM??

Hello there everyone!!
We have two Nexus 6 in the house, both at the moment running the superb six rom, but my wife does not like nougat, and loves lollipop and marshmallow, I think you can just download a marshmallow ROM and flash.....is this true? And the same for lollipop? Or do you need to flash completely a new firmware image? Bootloader is unlocked

You can flash a MM ROM and MM Gapps.

That's what I do when I get tired of nougant, I just flash MM, vice versa.

What about Lollipop? The Nexus 6 originally came with Lollipop. Can I flash a Lollipop rom on my Shamu despite the fact that I have upgraded all the way up to 7.1.1 Nougat? Bootloader is unlocked.
Personally, I miss the days of KitKat OS on Android.

I'm pretty sure that you can flash any ROM as long as its for the nexus 6. My favorite ROM was KitKat and always will be my favorite! But yeah, if you are rooted flash away my friend, any ROM ya want. If you are on nougant you may wanna update you're radio and baseband to the newest version? If you are on nougant and wanna go back to lollipop you may wanna consult a pro, and ask if there is anything you need to flash besides a LL ROM just to be safe. I know I was on nougant and I updated my radio/base to the newest version, then I flashed a MM ROM and everything worked great. You may be good though, I would just ask a dev just to be sure. I have a little knowledge but I still consider myself a newbie because I don't know squat,lol. J/K I know a little.. Don't flash anything until you get a second opinion. I don't want you mad at me if ya break ya phone.

Don't attempt to downgrade the Nexus 6 bootloader though, that's a good way to brick the device.
