Hello, I bought Samsung Galaxy before few days.. As I read in some forums n blogs about updating the phone that would increase the performance and especially the battery life which is too low in my mobile 1.) Model Number - Galaxy 2.) Firmware Version - 1.5 3.) Baseband Version - i7500DDII3 4.) Kernel Version - 2.6.27 imtrs@SE-S506 #5 5.) Build Number - 76XXCSDCBALUM6375 Now, i have installed latest version of NPS and its showing me 1 update of phone, but is not able to update. Please tell me can i update to version IH8 or IK4 ? Can I update using NPS or some external software like ODIN ?
