Ok. This uses the vr-theme script. Most of the a.b.b. theme uses it as well.
If you unzip flash me.zip, and go inside, you'll see this
Drill down into the vr theme folder. . .
You see a folder with the exact same name as what you're modding. Please note that it has the exact spelling, including the .apk. I'll get to how I chose what's inside in a minute. The way I get what's inside was I unzipped thee abb theme, and got to the SecMms.apk app. In abb it is a full app. So to get into it, use a file explorer. I used es file explorer. Long press it and choose to open it. If you just short press like normal, it will try to install it.
When you open it go into the res folder.
Then I chose this folder to extract (because it had the images I wanted)
And when you back out, you get this
Go into that folder, you'll see a bunch of pngs. I delete the ones I don't want to change. I'm left with
For your zip, I made all these images transparent.
I then placed the SecMms folder to the flash me in the correct folder (vr-theme/system/priv-app, for this mod) and renamed it to include tha ".apk".
Then I zipped it up.
A couple of side notes:
Any .9.png files... don't modify those unless you know how. Google it if you really wanna know.
Any .png files... if you replace it rather than edit it, 1. Make sure the name matches exactly. 2. Make sure the dimensions match exactly to ensure it shows correctly. If it isn't the same, crop or resize.
