HI there can anyone tell me why it takes so long to down load the new ics update through samsung kies? i keep geting time outs after 2hours!yep you read it right 2 hours and only 25% down load,im using a 2deg usb stick at 3.6mbps or something like that, same thing happens if i use my phone by hotspot,funny thing is i can down load 100mb file on my phone in about 5min,so how fast does your connection need to be through kies.
Simply put: Kies is crap. When I first tried to use it to do a firmware update, I think I tried about 3 or 4 times to get the firmware down, but had problems every time. That's on a DSL connection that normally gets good download speeds.
There are other ways you can use to download and install the firmware. Head on over to the SGS2 owners thread and have a look at the last few pages. There are download links to the Telecom firmware there and plenty of people to help out. I'd give you more info now but I'm typing this on my SGS2 and this site doesn't play that nice with the phone's browser.
TENKAN: Hey tell us about what type of connection you used,no problem at all with using kies?and do you know how many mb it was,thanks
I don't think the connection matters. As I mentioned above, I used a solid ADSL connection to try my downloads and they kept on failing. The only possible connection-related issue would be the backbone provider, and there are 4 of these in use in NZ. It's possible that one or more has issues talking to Samsung's servers.
The firmware packages are generally between 350MB and 400MB. Kies appears to start the download fresh with every flashing attempt, so you can easily chew through a bunch of your data cap with only a few tries.
As I mentioned above, there's a more reliable way of doing the upgrade. It involves using a tool called Odin, which is what Samsung give to cellphone repair centres for doing firmware flashes. It's nowhere near as friendly as using Kies, but it is guaranteed not to give you download grief.
Warning: Flashing a firmware via Odin will overwrite the /data portion of your phone. This is the part of the memory that holds your apps and their settings, so you'll effectively be doing a factory reset. You may want to use a backup utility (e.g. MyBackup) to save your SMS/contacts/calendar information so that you can restore it after the update. The good news is that any data on the internal SD card (e.g. music, photos) will be left alone.
If you want to give the Odin method a go, the best place to get started is to read this thread on XDA Developers. It gives you a step-by-step walkthrough of the process, so you can get an idea of how involved it is. Make sure you read the first post thoroughly, because you don't want to mess this up! (You can ignore the Quick Root Guide section if you don't want to root/jailbreak your phone).
The last bits you'll need are the Odin tool (200KB zip) and Telecom firmware (390MB zip). When you've got these files downloaded and their contents extracted, just follow the guide and with any luck you'll be back up and running in no time.
Just one more thing... If you're unsure about this at all, it may be safer to just stick with the firmware you've currently got.
The new firmware doesn't bring all that many improvements. If you're not a serious Android user, you probably won't even notice what's changed. There are also reports that the battery life isn't quite as good as with the older firmware versions.
Unless there's something in the new firmware that you know you'll benefit from, or there's an app you want to use that need Android 4.x, it's safe to stick with what you currently have.
