[Q] Have Cog 3.02, want 3.04...

[flintdragon]

I'd like to flash to Cog 3.04 directly if possible without Odin'ing back to 2.1. Is it ok to flash directly to 3.04 and if so, what the best way to wipe everything first to start form as blank a state as possible? I'm without a windows PC right now...

Thanks!

You can try that but no guarantee that it will work.you may run into problems and have to flash back to odin then you will be sol with out a computer

You should be fine flashing from one version to another. If you enabled lagfix I'd disable that first, and to be on the safe side do a CWM backup, but other than that you should be fine. I've been flashing another ROM back and forth without going stock many times without issue.

You can go and flash custom ROMs on top of each other and it might work, but don't be surprised if you boot into Cog 3.04 and have to deal with a bunch of force closes or other weird behavior.

I ALWAYS recommend people flash back to stock and Master Clear/GSM Master Reset. That gives you a blank slate to work with. It takes less than 10 minutes, but some just believe that's too much work/time for them.

Your call.

I've never had an issue flashing updates on top of Cognition. I'm pretty sure as long as your lag fix is the same between versions then there should not be any problems.

I flashed serendipity 5.0 over 4.3 last night with no problems. I just disabled lagfix before I did.

Thanks everyone for your helpful input.

Is it possible to master clear without going back to stock? I'd like for everything except the external sdcard to be cleared.
