If I understand correctly, you're currently on a ROM and wish to flash a different because the kernel changed?
If so, you can reflash the ROM your currently on and restore the original kernel. Make sure to wipe cache/dalvik/system (you don't have to wipe data) then relfash your ROM. You don't have to wipe data if flashing the same ROM you're currently on. If switching to another ROM, make sure to wipe everything except internal SD card (data/cache/dalvik/system).

Before flashing any rom including Omega you should do a full wipe in recovery for best results.
Omega rom does NOT delete everything from your device, none of the custom roms do that.
Good luck and be sure to wipe before flashing...................

If you wipe it all then all is gone from internal sd.
But you have to full wipe for good result..
You should root the stock rom and backup all user apps with TITANIUM BACKUP and then wipe and flash Omega rom.
After flash you just inatall TITANIUM BACKUP again and restore all from backup...

[Q] Trouble With Flashing CM10.2 and Wrong Kernel

So I was running CM10.1 nightlies with Franco Kernel and decided to make the jump to CM10.2. The ROM and gApps flash went just fine, but like a dummy, I flashed the version of Franco kernel that I'd been using before, which I guess is not compatible with 4.3. The phone seemed to be softbricked and would just hang at the Cyanogen boot animation. I can get into recovery and I've tried to reflash both CM10.1 and CM10.2 - both hang at the boot animation. I can go back to my stock backup just fine, but then when I try to flash CM again (either version), I have the same hanging problem. Does CM store like a memory of the kernel that you have flashed and try to revert to that? Why can't I flash CM again once I've gone back to stock (and the stock kernel)? Would reflashing the stock image fresh (rather than using a TWRP backup) change anything? I'm pretty inexperienced with this and would appreciated any help. Thanks in advance!

Just to be sure how much juice was left while you were flashing CM rom?? Reading your problem I would suggest you to do a fresh Stock image installation and then try flashing CM 10.2.
Have you tried restoring your NANDROID backup, if you made one??

I have restored the NANDROID backup successfully, but unfortunately I was lazy and only have the backup from when I first got the phone.
I backed everything up with Titanium Backup right before I tried to flash CM10.2. If I do a complete stock reflash, do I lose all the data I backed up with TB? I do have some app data that I would really like to keep if possible.
One other resort I thought of was flashing a different custom ROM (Paranoid Android maybe?) and then restoring my TB backup. Would there be any reason that I shouldn't be able to reflash CM after I've restored the stock NANDROID?

Try this.
As you are able to go in recovery,
Wipe cache , dalvik cache, system, data install PA 3.97 flash pa_gapps then supersu v1.51(for root,also enable app+adb from developer option)
wipe cache and dalvck again and reboot..
P.S : Charge your battery first to 80% minimum and flash the rom.
If the above doesn't help,
Backup all you valuable data into pc, backup app+data through TB move it to pc and flash the factory image through fastboot.

I ended up flashing the stock image and completely wiping all data. I then tried to install CM10.2 again and it still hung at the CM boot animation for about 15 minutes. It shouldn't take that long to flash, right?

[Q] ROM Downgrading nexus 4

Hello everyone, I am a newbie in flashing ROM's rooting etc.
I am currently running on CM11 on my nexus 4 with android version 4.4.4 . I want to flash a CM11 based rom for my nexus 4 which is 4.4.2. Do I need to wipe data before flashing it?
ROM LINK THAT I AM GOING TO FLASH http://forum.xda-developers.com/nexus-4/development/rom-xl-z1-rom-v2-0-xperia-z1-style-t2630043
Thanks in advance!!
Make a nandroid backup of your current ROM and flash the new ROM after wiping cache, Dalvik, and system. If the phone bootloops, wipe the data in recovery. If the phone then boots, you know that some of the apps may not be compatible.
Thanks

Another option would be to use titanium back-up user apps, wipe data and then flash new rom. (definently shoul do an nandroid regardless)

[Q] Flashing 4.4.2 Rom on 4.4.4

I want to Flash Sammy Rom, which is 4.4.2 Based, but my phone is updated to 4.4.4? Will I be able to flash the rom like I normally flash any other or is there another process?

Sammy Rom is a TW ROM. If you're coming from an AOSP ROM you will want to do a factory reset in you're recovery.
First, make a backup from your recovery in case you don't like the new ROM or you have issues. After you have made your backup do a factory reset. After you factory reset flash the new ROM.
You can backup apps with Titanium Backup or something similar if you want to try and restore them on your new rom. (may not work)
Good Luck!

Okay because I'm coming from liquidsmooth. If I do a factory reset, then will that wipe my internal memory?

I think he is mixing up some words. He means to wipe your device in the custom recovery, not to factory reset it.

So clean wipe, then flash like normal. So 4.4.2 will not create an issue on my S4 because it's on 4.4.4?

Yes do a clean wipe as you say. Inside ROMs it is sometimes called a "Factory data reset" or something along those lines. It is the same thing in the end.
Thanks guys.

Need advice on restoring backups

Hello
I recently rooted my LG G2 and installed Blisspop rom but i wish to go back to stock. Would this be possible to revert back to my stock backup or do i have to reinstall the firmware completely ?
Thanks any help is welcome
Any one can help me ?
Before installing a custom ROM, did you use TWRP to create a backup of the stock ROM? If you did, you could try restoring the stock backup from recovery.

i did indeed i backup up via TWRP but im getting confused cause i keep getting told different things like i need to have a different boot loader etc
The only thing i did was flash the ROM i didn't flash any modem or boot loader to my knowledge
Restoring the TWRP backup should leave the bootloader and modem alone.

You may have to wipe the cache and data, especially if you are going from lollipop to kit Kat or vice versa.
