Yeah i know, however it isn't bad to do some research on how to use Odin, as I already had to fix my phone which was stuck at bootscreen, and I was unable to get into recovery, only in download mode.. So only thing I could do was flash stock through Odin, was happy to know how it works..
-Fast and stable SGS II ICS 4.03 ROM
*Based on original Firmware
*Better optimised apk's, framework for more speed and free mem.
*Customizable 14 statusbar by lidroid
*Large APN list
*Fast GPS lock
*SD card read tweak
*Root + Busybox
1 - disable start on booth of SetCPU (Speedmod kernel does not support it)
2 - disable LaunchePro as default launcher (you'll not fin it in 5.0)
These actions alone should avoid bootloops, but in case...
3 - backup your data (to recover from bootloop you'll need hard reset and full wipes)
4 - be ready to flash a stock KG3 rom if you want to go back to 4.x or lower
You don't really change the resolution, thats impossible... the only resolution you have is 800x480 no way around that.
What you can change is the DPI setting and that fakes how many dots there are in a inch.. By default the samsung with its 4.3 inch and 800x480 pixels has 240dpi.
When you lower that to 200dpi what you do there is tell the system if they want to draw an icon that is 1 inch big, that it should use 200 pixels instead of 240 pixels. That means that everything draws itself almost 20% smaller..
So i guess in Android almost everything is not really drawn on screen by hard pixels but by the inch/cm size.
"In the rare event that your phone cannot boot because you left this checkbox checked at unstable frequencies, create a file called "setcpu_safemode" (with no extension) and put it in /data/local or /sdcard. If SetCPU detects this file, it will ignore all start up settings."
