[Q] Switching ROMs - LG Optimus L9 P760, P765, P768, P769

Hello,
sorry if this was asked, but I wanted to know what should I do if I wanted to switch roms? For example from CM 10.2 to CM 10.1, do I need to reflash stock rom, or can I just wipe data and cache in recovery mode and just flash another rom on top of it?
Thanks in advance!

You should be fine with just wiping cache, & dalvik, then flash the Rom.

Yes, if coming from a GB based rom you should wipe date/factory reset.
Is there any reason why you cant? All you need to do is backup apps/app data with Titanium Backup and then restore once you have fresh rom.

1. Yeah full wipe is recommended if you are downgrading or upgrading to another Android version.
2. If you don't do full wipe there are chances that your CM9 will not bee stable, freezes and lockups here and there
Swyped from Samsung Galaxy SII
What about an ICS stock rom? that's the one I'm using right now . If I install the CM rom, and if I want to downgrade to the stock rom again, could I do that? Thank you for answering.

If you are moving from stock to Aosp Roms and vice versa, you have to do full wipe

Yes, you would just flash the stock ROM using Odin, and that would "unroot" your handset in the process.
If you try to switch from stock to a custom ROM, or between different custom ROMs without wiping your data, you can soft or hard-brick your handset. It's not worth the risk.

I've just downloaded the update through UpdateMe and flashed it. It recognised that it was upgrading and upgraded fine without a full wipe.
If you're simply updating an existing ROM or coming from a ROM with the same build base, all you need to do is flash it and clear cache partition and wipe dalvik cache.

Boot into recovery, wipe cache, factory reset and install the 13022013 nightly update (last 4.2.1 rom and gapps). It should boot up.

thanx a lot it worked!
Had same issue.
Does this mean that if you want to revert to an older nightly you can't use the ROM built in update functionality ?

If you do that you will likely bootloop as there will be file residues from the previous newer nightly. So it is better to flash the older nightly with recovery but you have to wipe before flashing.

Back to CM7?

Hi! I have ReVolt ROM on my I9100. 4.2.2 Android version. Is it possible to flash CM7.2 stable? Do I need an older recovery, or can I use a newer one? I want to try it. Thanks! Sorry for my bad english!

Thanks for your reply! Yes, I want to try CM7, because I bought it with stock 4.0.3. I have not seen Android 2.3 on SGS2.

Do a full wipe i.e. wipe data, cache, dalvik cache then flash the ROM and gapps as well!

First of all you should always make a backup in case something goes wrong...usually only you should do is download the rom to your phone, reboot in to recovery, wipe cache, in advanced..wipe dalvik, then just go in install zip from sd card, find downloaded rom and install it, then reboot and everything should be fine
if it's not, factory reset
Backup first in recovery then flash in cwm..
