[Galaxy Ace II Android Development] WiCiO_MeDi:
Lite version of stock firmware: UK I8160XXLK7 (built 30.11.2012, changelist #1214896).

Rooted with SuperSU v0.99

The ROM is for ODIN flashing and it won't increase your flash counter.

There's also a ZIP version for CWM/TWRP.

You can always add CWM and custom kernel by ADB and dd command also without increasing the counter so.. make your own decisions from now on :D

Apps added:

AppWidgetPicker v1.2.3: groups widgets in selection screen

HoloLauncher v1.2.8: fast and light ICS style launcher, alternative to TW Launcher

Installation:

1. Download and flash stock LK7 ROM:

United Kingdom (sammobile hotfile)

2. Download and flash lited LK7 availible in two versions:

aeM_ROM_v1.3 for CWM/TWRP - 206.13 MB (dev-host)

aeM_ROM_v1.3 for ODIN - 175.14 MB (dev-host)

3. Check if I bricked your phone.. (just kidding ;) )

Side notes:

Use 7zip to unpack downloaded files (http://7-zip.org/)

Use Odin v1.85 to flash (https://docs.google.com/open?id=0B9GFVatYEi9jbWYtalVMVFdBbWc)

USB Debugging in Settings->Application->Development must be ticked on for proper rooting

Flashing stock LK7 and lited LK7 wont remove your apps and files. It just reflash the system partition.

I've removed google apps (gmail, youtube, maps) so if you use them just download them from the market.

Try using Holo Launcher which in my opinion is superior to TW Launcher.
