OK, i'm ready to flash stunner 4.5 version.
currently i'm on substancer LA6 with abyss 4.2
for clean installation:
Install Mobile ODIN (Pro version preferred) apk and flash ICS-Repack.
Keep EverRoot and Wipe Data checked. Start Flash.
After everything goes ok, you get ICS leak repack. Let ROM settle.
Shutdown.
Hold Volume up key and long press power key. Open Recovery Mode.
Wipe Data.
Flash downloaded ICS Stunner ROM.
However, the first post says:
NEW STEPS BETA 4.3 ONWARDS:
Backup data apps.
Download and copy latest Stunner ROM on your SD Card.
Make sure you are on Rooted ROM. Reboot in recovery.
ONLY IF YOU ARE ON GINGERBREAD: Flash Abyss Kernel. Goto Advanced and Reboot Recovery.
Wipe Data (Recommended but not mandatory if you on Stunner ROM already)
Flash ROM.
Flash suitable Modem (Optional, recommended ICS LP5 modem)(not included in ROM)
Reboot and Read Caution.
Do not restore system apps or system data.
How come second part does not say need to flash ICS repack?
Yesterday, I tried the second option which was to flash Beta 4.4 without flashing the original ICS repack first... Everything looked and worked great except that I found I lost root when I tried to access mobile odin... I don't know if it was my mistake but you may want to check on your root if you go with the 2nd option... Hope this helps.
I'm going to try Midnote 3.2 now...
