[Q] Is there a guide to updating to KitKat from an older ROM of KitKat?

My dad's phone has a custom recovery and has a ROM of the version of KitKat before the OTA. Have ROMs been updated to support the official release yet? How do I know which ones are on the new or old drivers? Would it simply be to flash the ROM through the recovery, or do I have to go back and install the OTA, then flash a new recovery and ROM?
Thanks.

Swapping between 4.4.4 and 5.0

I'm rooting and running Dirty Unicorn 4.4.4 ROM.
If I flash a ROM that's using Android 5.0 and use it for a while can I then just flash a ROM using 4.4.4 and not have any issues? I guess i'm asking if it's possible to just flash any working ROM running on either 4.4.4 or 5.0 (swapping between them) and it work?

You'll need to wipe going between 4.4 and 5.0 custom ROM. Once you've set up new ROM once, and have Nandroid backups of both, you can go back and forth

Is that wise? Going from a KK based rom (CM11), to a L based rom (CM12)?
I'd advise user to wipe data, maybe even update to stock LRX22C and from there, flash twrp and cm12.

If he has a clean CM11 installation he can easily flash CM12 without wiping anything.
If you're on stock ROM and apply the OTA update you're also going from KitKat to Lollipop without wiping anything.

Official statement:
You can flash CM12 nightlies directly from CM11 M12 or CM 11 nightlies (no need to wipe), provided you read and followed items 1 and 2

The OP's question was whether you could flash CM12 over CM11, not whether or not it would boot up

@Lethargy: That answer made my day :'D

Revert from HammerheadCAF to Hammerhead?

Hi guys,
I flashed my bootloader and TWRP in order to install CM 12.1 NIGHTLY HammerheadCAF ROMs. It's working fine, but now I want to try the Android M preview. Do I just have to flash the original bootloader and non-caf TWRP and be back to normal?

Flashed stock images via fastboot and back to normal.

How to install CM13 on XT1033 running CM12 with custom kernel Hurtsky Stable 13?

I want to install MM roms on my phone,stock or CM based. But the problem is that I installed Hurtsky Stable Kernel for 5.1. Do I need to flash a stock kernel of 5.1 to be able to flash 6.0 roms or do I need to flash any kernel for 6.0 roms. And if I do flash a stock kernel for MM rom while running CM12, will my phone boot?

You have only to make a full wipe via twrp recovery (Wipe system, data, cache, art-cache) and install zip of CM13 and gapps.
Download the main system zip from: https://download.cyanogenmod.org/?device=falcon
And the gapps from: http://opengapps.org/ (choose the 6.0 one).
There aren't stock based, because Moto G 1st gen (2013) does NOT HAVE 6.0 official!
There is also an Identiti crisis rom, a porting from moto g 2014, but CM13 is more stable!

All right.Thank you for replying! My concern is about the kernel. The kernel I flashed is meant for LP CM Roms and not MM. So when I flash CM13 with gapps,won't it create a problem? Will I have to flash stock 6.0 kernel or a kernel for MM CM Roms?

No, the kernel is replaced when you install a ROM. The kernel is a part of system, the heart of ROM, contains all the driver (called modules) and also set the CPU and GPU frequences. So you don't have problem if you install the zip because in the zip there is the default 6.0 kernel (if you see in the zip there is a file called boot.img).

Ohh! Thanks a lot! I shall try CM13 now!
