[Q] changing rom form v7.1 rc to nightly builds - HTC Aria Q&A, Help & Troubleshooting

should i do wipe delete and all that or just update over it?

The RC1 is actually a couple months old now and was based on Android 2.3.4. The latest nightlies are based on Android 2.3.5. Since it's a different version of Android, it requires a full wipe to upgrade.

[Q] Can I safely downgrade from CM 11?

Hello, I have an S3 LTE version, I'm currently running CM KitKat, but the bugs (mainly the camera) annoy me very much. I wish to downgrade to some stock based 4.1.2 CF, TGP or something, but I fear that it will format allof my data, because I have heard that KitKat started partitioning the drives differently. Is it safe? The camera on CM 11 freezes randomly thus making it unusable for me. I've read the FAQ and this is disturbing:
How can I return to a 4.3 ROM from 4.4 ROM?
Flash a 4.2 Kernel (or lower for lower versions) and use the CWM Recovery to do the Full wipes, flash the 4.3 ROM you want and reboot.
Do I need to do anything else than installing the ROM if it's got the AROMA Installer?

[Q] Rom building to new device help

I want to build cm11 for the T-Mobile Sidekick 4g primarily for compatibility with newer apps, but before that I was told that I'd first need to build a kitkat compatible kernel. I have read on how to build kernels, apply patches, tweaks, and modules, but I haven't seen anything about what makes a kernel android version specific. I have an HTC HD2 flashed with Tytung's nexushd2 cm based roms and on his list of roms he has used his same custom kernel on both jelly bean and kitkat roms. So my questions are;
1. is there any other way to make newer apps like hangouts and stock nexus 5 dialer (because of native sip integration) compatible with older versions of android (froyo)?
2. what makes a kernel android version specific?
3. what would I have to do to make a sidekick kernel compatible with cm11?
4. would the cm guide here automatically build a cm11 compatible kernel? http://wiki.cyanogenmod.org/w/Doc:_porting_intro
5. is there any way to update sidekick 4g stock rom source?
6. if I build using Google AOSP source would the rom that is built be a nexus-like rom?

[Q] Question on Android version

Hi,
I'm currently running on Paranoid Android 4.6 beta 5 and would like to move to Android Revolution since I'd like to get MHL functionality.
I am currently on Android 4.4.4, so my question is if the Android Revolution ROM (which runs on 4.3 Jelly Bean) will work on 4.4.4, or if I need to downgrade (if that's possible) the Android version first.
Thanks.
No, just a full wipe of system, data, preload and internal sd is required to change version.

Cyanogen apps on PA 12.1

Cyanogen recently released a gapps like package that contains several apps previously exclusive to the retail version of cyanogenmod. I'm wondering if there will be incompatibilities if I install it on paranoid android 5.1. PA is based on 12.1 but I want to make sure it's compatible.
TrueCaller looks like an app I want on my phone.

[HELP] Upgrading Android version of a ROM

I'm very new to android development, so pardon any noob like things.
I want to update the version of android of some custom rom, could I do that by cloning aosp of that newer version and then merging the custom rom(old version) with the newer aosp.
If this is not possible is there any method that can be used to upgrade the android version
