Root dirty flash?

[d4rk13l4de]

What exactly does this mean? I have searched but have found anything. I'm looking at updating meanrom to 3.9

It means wiping only dalvik cache and cache when flashing an updated version of the same ROM you are currently on.

You won't lose any settings or data

Last flash remark i made was deleted by a red guy it was funny though

I read it and tried to like it post delete but it wouldn't let me

I had flashed the new clean rom and was running it. I got a little exuberant cleaning it and started getting some fc's.

Another prob I had was that open signal maps app would not work, found out I need to have all the google location stuff on for it though.

anyway, I restored a nand of it but it was apparently made after i messed it up. or maybe it was before I figured out about the open signal thing, but, point is, I figured I would dirty flash it and fix what I had messed up but keep my set up.

No go, I hadn't wiped anything, but when I was through flashing, it was all new again, nothing saved.

Quite the opposite of my experience with the Mean iterations.

Some devs have it in the rom updater script to automatically wipe everything when you flash it.

Easy enough to undo their additions. I wrote a tutorial for it on the OG for MikG

you need to change the updater script to do a dirty flash with those roms that automatically clean /data and /system files. the /data is the important one. Its ok to delete the /system partition as it will be re-written. I remember Rx having to do that for the Mik G rom for a customer I didn't remember the guide he wrote though Dirty flashing is best left to those who are advanced enough to know what they are doing. its really not for the faint of heart. As always you should have a Good Nandroid you can go back to for when the dirty flash does not do what was expected or wanted.

Or you can just do a backup with twrp and then after the flash restore just the data section. That's basically the same thing as a dirty flash.

true but doesnt it defeat the purpose besides its more fun to edit the ROM

I can't argue with that at all...

This seems to be the latest craze over at XDA for some reason. I guess the peeps over there think they're getting a clean install doing it that way. I asked if they knew it was the same thing as a dirty flash but only one person even acknowledged my post. Oh well, as always do whatever gives you a warm and fuzzy. lol

I just do some very selective system data restoration with TB. That way I get a clean install and keep my settings.

The full system data restore never seems to end well for me though, so which is why I only restore a few things.

Will this save apps?

Yes, dirty flashing prevents any data loss.

It's only for rom updates though not going from one ROM to the next

Well I don't want to tamper with the recovery or anything. And now Google play remembers your last installed apps and installs them on start

If you use Titanium you can restore the app and the app's data (saved games, and login info, ie)

Going to try this dirty flash here in a bit. Backed up all my apps just in case though.

Worked like a charm!
