UPDATE: 2012-04: Wotan is no longer free. Use the FlashTool. In this video, I show how to use the paid Wotan Client to flash your Sony Ericsson phone. While I'm only flashing my arc, it works on the X10, Play, Neo and many others. Visit www.wotanserver.com to see the list of supported phones, create a free account and download the client (located under http Wotan Server has many different firmwares from all around the world for many different build versions.eg v2.3.2, v.2.3.3, v2.3.4, Build 4.0.A.2.368, etc. The NEWEST Xperia firmwares as of 2011-11-01: arc: 4.0.2.A.042 X10: 3.0.1.G.0.75 Complete index of X10 firmwares: forum.xda-developers.com Typically, it is the firmware with the higher number, obviously. Your phone does NOT have to be rooted (flashing wipes EVERYTHING annyways). Your bootloader does NOT have to be unlocked (it also does NOT unlock your bootloader). It does NOT SIM/network unlock your phone. It does NOT re-lock your phone if your phone is already unlocked. SIM/network unlocking is completely independent of any firmware and in unaffected by any flashing. You can flash ANY corresponding firmware onto ANY corresponding phone regardless of SIM lock, bootloader condition or root. eg flash a generic PLAY firmware onto a branded PLAY phone and vice versa. flash a branded Neo firmware onto a generic Neo phone. etc. WARNING: DO NOT downgrade from v2.3.4 back to v2.3.3 or v2.3.2 or you may experience the 0% battery issue.
