I am currently using samsung galaxy 5 i5503.. Unfortunately Galaxy 5 I5503 hasn't qualified to get Froyo update (Android 2.2) although it should have, no compatibility issues. Anyway, I was determined to get Android 2.2 running on my Galaxy 5 and was successful too! A big thanks to Samfirmware for Android 2.2 firmware for Galaxy 5 series phones (I5500/I5503).
The process to install and get Android 2.2 running on your Galaxy phone is very easy. Just follow the following mentioned points in order and your mobile phone will soon enjoy all the features of Android Froyo ...
files needed before u start are as following...
Original Samsung Galaxy 5 cable
Android 2.2 firmware
here are the steps to flash your phone..for the update..
1-->::You must have downloaded all the files mentioned above and keep them ready..
2-->::Backup all the contents of your phone memory with KIES or using Mobile Back Up II[available on app store...]
3-->::Reset your phone to factory settings (Not compulsory but advised). ;)
4-->::Make sure the battery is fully charged up.
5::Switch Off your Galaxy 5 (I5503/I5500). Remove battery and re-insert after a few seconds.and reinsert it..
6-->::Press the following buttons together:
Volume Down Button + Center Home Button (Big square) + Power Button[call end]
7-->::Wait for “Downloading” screen to appear. Once this screen comes up release the buttons and connect your phone with computer using original data cable.this screen would be yellow droid digging up some thing...
8-->::Now wait for your computer to install device driver (until it shows “the device is ready to use”). In the mean time extract the I5500LUYJP2.rar file which will give you a I5500LUYJP2 folder with I5500LUYJP2.tar file in it.
9-->::Now open ODIN Downloader (downloaded above), if the phone connection is successful the box under COM Port Mapping will turn to yellow. Select the following check boxes ,,it is also shown in 2nd screen shot..:
-->>One Package, Auto Reboot and Protect Ops check-boxes.
-->>Select the Ops file (downloaded above).
-->>Select the tar package downloaded above.
10::Cross check the settings and hit “Start”.
That’s it! In approximately 5 minutes your device will restart and boot into Android 2.2 with beautiful icons and lots many new features..like wifi hotspot..and main feature of froyo..u can install application in your sd card,,that is not supported in eclair[2.1]..
