I have a question - LG Optimus 3D

If I have cm7 on my phone. And I flash a cm7 based rom do I have to do a full wipe?

Read the op for the ROM you are flashing. It will tell you what is recommended. You can always try to flash it without wiping and if doesn't work right, do a full wipe and flash again.

Try installing setcpu and seeing if that fixes it.
Just install it no need to open it.

Have you tried a fresh install? Always works ;-)

What do you mean by a fresh install?

A fresh install means wiping the dalvik cache and factory resetting the phone in recovery mode before flashing the rom. Best use titanium back up if you want to keep your apps

Do you remember doing anything to your phone before the fcs started?

If it always has been like this, you've most likely corrupted the ROM file during download.
Download it again and install it after doing a factory reset & caches wipe.

Thanx bro it worked!!!!

What's dirty flash?

Is dirty flashing when u go into goo manager and flash roms like that? From one build to another.
Sent from gs3..
No dirty flashing is when u flash without wiping your data.

I believe that's how goo manager does it
That's how most any of the apps made do updates to ROMs. CMupdater does it, I know that for a fact.

Back to "stock" ROM kernel?

Can I go back to the kernel that came with my ROM? I'm running Liquid 4/20 nightly with KT kernel currently and want to go back to "stock". Any way to do this without reflashing?

You will have to reboot into recovery and wipe data. It will take you back to when you first flash the ROM.
Thanks for the response.. What all will be lost with data wipe? Will I still have downloaded apps?

The user wants the stock kernel which came with the ROM. He has to flash the Kernel or flash the ROM once again after wiping the data.

Yes this is exactly what I'm asking about. If I don't have the kernel and I reflash the ROM after the data wipe, what will I have lost when the phone reboots? Maybe a better question is what will I need to restore as I've done a full backup.

When you dont wipe anything and flash the rom, you won't loose anything as far as i know. This method is known as dirty flashing. This may sometimes causes unintended issues.
If you wipe cache, dalvik-cache, boot, system and data and flash the rom, you will loose all the apps installed, messages, contacts etc. This is full wipe, clean install.

Thanks a lot for the response. I'm just getting into all the amazing customization options and I've become a flash addict lol. I'm seeing the full benefit of nandroid now... Definitely your best friend.

you should wipe everything before flashing a new rom
read the instruction
Don't forget to hit THANKS button
[Q][URGENT]Is This Fixable?
Every time after that time I wiped everything but I forgot once. Would forgetting to wipe everything cause something like the issue I'm having? And if so is it fixable?

Did you flashed a completely other Rom? Or only an"update" of your Rom?
If you only "updated" your rom:
Boot into recovery
wipe Cache Partition
and Wipe Dalvic Cache (under "Advanced")
Reboot
This won´t delete any User Data
New ROM :-[
