[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 !!

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.

Moto G 2014 XT1068 became very slow after upgrade to v5.0.2

Hello everyone,
The phone worked fine with version v4.4.4 after the upgrade (v5.0.2) he became unbearably slow.
I do not know too much about root, rom and and so (last time I change rom it was on my HTC Desire ).
Generally I would be happy if there is a simple way (or at least a detailed guide) to restore the phone to the version he came with.
I would appreciate your help :fingers-crossed:

If you want to restore to stock 4.4.4
Then go to the general section of this phones forum and search for your model and the firmware (4.4.4) you want. Then just follow the steps to restore. (I can't tell you which firmware since you haven't mentioned your phone model). Or install CM 13 Official, it's stable as hell, and its better than stock. (Guide to flashing roms also exists).

Thanks for the quick response.
My phone model is Motorola Moto G 2014 XT1068 as appearing in the title, any additional information needed to specify ?
About CM 13 Official from what I've read here and in other places It seems like if it not stock there be problems like camera does not work, low battery, problem with SMS and so... Or is it only in certain versions ?

Sorry. I didn't read the title properly.
This link : Stock 4.4.4
There's no thing wrong with CM. It's better than stock for sure and there's no additional problems seen when you use CM. Just don't flash Xposed.
Its stable and fast even though it's in Alpha stage.

Thank you !
You have any idea how do I know whice fireware I need ?
A) Firmware KXB21.85.14 (earliest version)
B) Firmware KXB21.85.23 (DSDS ALL)
C) Firmware KXB21.85.27 (latest version)
D) Firmware KXB21.85.23 - GB Region (UK)
E) Firmware KXB21.85.14 - DE Region (Germany)

Depends on your country.
A and B should work on ANY XT1068 as it's a Retail for ALL Dual sim, (it may or may not have certain languages)

official support of the M7 stopped at android 5.0.2 for Sense version and 5.1 for GPE version.
You'll only find custom rom for Marshmallow and Nougat. I wouldn't recommend Marshmallow roms, they are unstable. Nougat roms work fine when used with the GPE firmware.
Don't forget that you shouldn't create 2 different threads for the same thing (read forum rules).

I hadn't had issues while running custom roms after 5 years.

I assume it's next to impossible to flash the GPE firmware if you're S-ON right?

Asus Me572C upgrade ??

Hello to all
I have an Asus ME572C (K007) tablet running Android 5.0.1 and I would like to add a newer Android to it in order to benefit from the latest Android features knowing that it has sufficient characteristics to run new Android but that Asus preferred to leave out.
Do you know if there are ROMs compatible with this model and which Recovery to use to do it?
I have searched well but I cannot find ROMs for this model.
Thanks for your help ! :good:
