There are quite a few Ice Cream Sandwich Android 4.0 based custom ROMs out there for the Samsung Galaxy S2 i9100, but it becomes harder and harder to tell them apart as they are usually the same ROMs with a few minor differences. Slim ICS ROM differentiates itself by being very slim and stripped down to come up at a small 75 MB size, by removing a few default apps found in other ICS ROMs.

Here’s a look at some of the highlights of the ROM:

  • 5 Languages ( en ( us, uk), fr, it, de, es) No additional language will be added.
  • Zeam Launcher ( stock ICS launcher provided in add-on package)
  • Basic Google Stuff Included ( 4.0.4 Gmail,Talk, Calendar and Contacts sync)
  • Market 3.4.4
  • Team Hacksung/CM9 Kernel
  • Rooted
  • Easy to customize.
  • 182 DPI ( use 240 for any incompatible apps or check here for Market workaround)

This procedure is compatible only and only with Samsung Galaxy S2, model number i9100. It’s not compatible with any other device. Check your device’s model number in: Settings » About phone.
