Till now I flashed my Samsung Wave two times which is actually working pretty good.
You should start the Platformdownloader before you connect your phone via USB to your computer. The downloader recognizes the phone after a few seconds and tells you which ports are ready. You must have installed the USB-Drivers on your PC before. You don't have to disable the MTP-Screen, but you can. The MTP-Screen "locks" the screen and displays that your phone is connected, in this case you cannot work with your phone while it is connected to the computer. To disable the MTP-Sceen, you have to dial *#6870# on your phone.
When you're connected with the downloader, your phone should display a mobile phone icon and an arrow pointing on the icon from the top. Now you're ready to go. Click the "Download" Button and pray
... sometimes the Downloader displays a security warning and you can't go on. If so, you have to reconnect your phone. Sometimes this takes more then one try. If you don't get the warning, the downloader starts with flashing your phone. This takes around 3-5 Minutes. The phone will reboot automatically and you're done.
To see the new version number, simply type *#1234# on you phone.
I'm currently running version S8500XXJE4, the CSC-Version is S8500OXAJE4.
The game 'asphalt5' is preinstalled with this version as it was 2 versions before. I now get a little bit more far when trying to connect to my Exchange Server, but I can't sync. I always get a "Connection error" message which is unfortunately not telling me the exact problem. Could be wrong password, could be wrong server URL, I don't know. I double checked all options and couldn't find any typos or wrong settings. Does anybody know if this is just not implemented yet?
Also, I'm still not able to connect to my full Google account. Only Google mail is working, but the full account with contact and calendar sync is not available. Twitter and Facebook work as expected.
As I had some more time yesterday to play around with the Wave I started downloading some HQTEST-Apps from the market. Some are really funny like the "Word World e-book" telling a story about a bug that can't sleep and a frog helping the bug finding a good place to sleep. Looks like some developers are a little bit bored
. However, with a 3G connection, the phone is really fun. Twitter, Facebook, App-Download, it's really working great. I also like the downloading animation on the phone, showing the app icon with less brightness and then "filling" the icon with "water" until it has it's full contrast.
I also have to mention the speakers of the phone. The quality of the speakers is really great. I use it all the time when I drive in my car. The sound/voice is clear and loud enough and nothing seems to vibrate or jam the sound.
Now, the feature I like most
Video phone call: The current version now does fully work. The versions before had the problem, that the called person had no chance to do anything on the phone when he/she received the phone call except for hanging up. Now, if I'm the one who receives the call, I can enable my video camera and the display is working while I'm on the phone .. great, I really love this feature.
To sum it up: A lot of essential things like synchronizing multiple accounts with mail, contacts and calendar are still not working. The video call bug was fixed, and the phone is still fun.
