Yes. to prevent any issues it is advised to wipe all data before flashing. One of the things you learn to deal with when flashing custom roms.

You'll want to wipe your data partition when you flash between ROMs. You can use Titanium Backup to backup your user apps before you flash CM (it might be a good idea to copy the TitaniumBackup folder off of your phone after you've made the backup if you aren't familiar with flashing or wiping, if you wipe the internal SD you're backups will be deleted!). Once you've flashed CM you can download Titanium Backup from the market and restore from your backup.
While you can backup/restore system apps as well you'll get weird results between ROMs (which usually results in wiping and starting over again anyway), so my advice is to only restore system apps/data when flashing the same ROM.

Your virtual SD card will not be wiped.

Stock unrooted MF9 zip? Or tar.md5 that won't wipe data?

Is there a zip we can flash in TWRP or CWM to go back to stock? I'm stock rooted with a couple tweaks (like hotshot mod) and I want to revert to full stock to take the MJA OTA. I'd of course need to manually flash the stock recovery afterwards via odin for the OTA to work.
I know I can odin back to stock, but that wipes data (and possibly the internal sd card as well, the thread isn't clear). I want keep data, since there shouldn't be anything incompatible with full stock.
I suppose I could backup the internal sd card, backup data with TWRP, odin to MF9, take the OTA, use cf to get root, odin TWRP back on, restore the internal sd from backup, and restore data from TWRP. But it would certainly be a lot easier and faster if there was a way to just go to stock without wiping data...

If you had research. Restoring data on 4.3 messes up your phone. You should stick with mf9 for now really. The only good thing about 4.3 is gear support but come with knox security which is being a pain in the a** for people now. But thats my opinion

4.3 should have the TRIM support (the main reason that I was interested in it)

I did research, the concensus was that titanium backup restoring wasn't working, and that was only when restoring the app itself (installing from the Play Store then restoring data only works). But restoring the actual data partition should be fine.
Or if that's an issue, and I had to wipe data, then I would just restore data right after odining to stock MF9 before taking the OTA.

If you use the stock mf9 tar to return to stock, all of your data will still be there, it does not wipe your data. Your system partition will be overwritten along with recovery, bootloader, and modem. But it will not touch your data. Download the one from sammobile and you should be fine.

Yeah trust me, there's a lot more good to 4.3 than just gear support. Trim support was my most anticipated feature i was looking forward to as well, but I can tell a huge difference In the clarity of the screen, and colors as well. Battery life on stock kernel has been ridiculously good.

Jumping from AOKP to Stock. How?

I'm stuck on AOKP 4.2, and would like to upgrade to stock 4.4 + xposed (been hearing great things about it). And I have a bunch of questions before I do the deed.
1. Can I just wipe apps + data and flash the stock image? Will that preserve my recovery (TWRP) and root?
2. Should I also get a 4.4-specific baseband?
3. I'd like to backup my contacts, along with the merged/linked data. How do I do that?

You don't need to wipe anything beforehand. If you want to preserve recovery, you'll have to flash each image separately instead of doing the flash all or remove the recovery image from the stock package, as that will prevent it from being overwritten. No, root can't be preserved because you are flashing a new system partition. You can simply flash superuser.zip afterwards, or TWRP may offer to root for you.
You don't necessarily need a new radio. Personally, I'm still using an older hybrid, for LTE purposes.
The best way would be having your contacts synced with Google. Otherwise, you'll need Titanium Backup for contacts and all other data anyway.

1) how are you flashing? if you use the autoflash through fastboot, youll lose everything. however, if you flash each partition manually through fastboot, you can preserve your current recovery.
2) if you aren't having issues now, i would stay with the radio you are currently using. radios are cross compatible between android versions.
3) there are a few root apps in the play store for contacts backup. if you have a google account, they should all be auto backed up (provided that you saved every contact to your google account and not your sim card)

I recommend you to use an official stock ROM, and install it. It will not preserve anything, so you should export your contacts, and restore them later.
After restoring stock ROM, you can install any recovery and root from fresh.

[Q] Restore SYSTEM partition?

I dun goofed and erased my system partition. I have backed up my DATA partition and have a few things.... but i would like to know if i can simply flash the system partition back from a stock rom, instead of having to system restore everything and have to re-root, etc.
Thanks.

Yes you can, use
fastboot flash system <system.img>
but it needs to be the same version you erased otherwise you might get a boot loop.

if you have recovery like twrp just flash the system image back. if you dont you might have to restore it.
Wugs tool kit works if you get stuck on flashing system see my response to this thread http://forum.xda-developers.com/showthread.php?t=2625843

Android 5.1 Update

Hi, So the Android 5.1 OTA is finally available for N4, I'm rooted with custom recovery and was wondering how can I flash the OTA?
I know a way which I should unroot and install stock recovery, but other than this is there any way?

Backup data, Wipe factory data and flash OTA update from custom recovery.

You can't flash an ota in a custom recovery. You can only flash it by sideloading in the stock recovery.
PO, you have to be 100 % stock, system, kernel and recovery to flash the ota. It's just as easy to flash the 5.1 factory image.

I always just flash the factory image. As jd1639 says, it's just as easy. And you don't have to go to the trouble of returning to stock. Just make sure you don't wipe out your data, unless that's what you want to do.

so to flash ota i would neet to loose data and go to stock right?
is there factory image i could use without going to stock then? Thanks

If you're on 5.0.1, flash the system, boot, and recovery images with fastboot from it. Boot into recovery and sideload the ota with adb. You shouldn't lose any data. Then re-Root.
