hello i was seeing the above post. last night i tried to install the 928 black glass update.
i have tc rom which was seemless for 928s 2.2 i tried to install 2.284b over the latter in hopes to get some more goodies. first did not wipe any thing, caught in the moto boot. next cleared cashe caught in the boot loader screen. I wonder should i wipe data and cashe. then try. last night was a bit tense for the longest time i could not boot into recovery so packed it in at 1am edt. question if i wipe data and cashe will my apps and set up still be there? or do i need to get a fresh rom then install. sorry for the long winded question. also hope this is the apropriate place to post.
I would think you should always install a theme over a clean version of the Rom. Saying that I did install over Blue Energy theme and it worked fine.
What I normally do is:
1. Install Rom and get all apps and homescreens set up and working
2. Backup
3. Install theme Make sure everything works still
4.Backup
5. Now If I want to change themes I just restore my clean backup and install new theme.
If you wipe data and cache you will lose all your apps and set up. But if you have Titanium Backup you can just restore all your apps, data and settings. The only thing you willhave to redo is your homescreens.
