[Q] How to update my specific model?

---

Hi there!

Right, so I have an unlocked and rooted SE Arc with Android 2.3.2
However I'd like to get the 2.3.3 version instead.

My Arc model: LT15i
Current build: 3.0.A.2.181

It's rather hard to choose in the development section so therefore im asking you: which should i take ?

thanks in advance

get the LT15i_3.0.1.A.0.145_GenericGlobal_system.zip (146.71 MB) from here : http://forum.xda-developers.com/show....php?t=1044201
Like said in the post better first flash : unrooted .145 Global tft from here http://forum.xda-developers.com/show....php?t=1105703

just follow the guide from the thread from kanzone ( the first link ) good luck
