How to upgrade to Windows Mobile 6.1 on HTC s730 / Wings

I’ve created a little package which includes all the files needed for installing Windows Mobile 6.1 on your HTC S730 / Wings cellphone. Kudos to Alcaline over at xda developers who have cooked this wonderful rom.

REMEMBER: BACKUP YOUR FILES BEFORE YOU PROCEED CAUSE THEY WILL BE GONE AFTER THE UPDATE. USE AT OWN RISK!

Now let’s have some fun:

1. First of all you need to install something on your cell called ‘HardSPL’. This will allow us to install our flash rom.
2. Download windows-mobile-6.1-htc-s730-wings.rar so you’ll have all the needed files and unzip it.
3. Remove all SIM and SD CARD!
4. Connect the USB cable.
5. Start the ‘SDA_ApplicationUnlock.exe‘ file located in the unzipped HardSPL folder to unlock your cellphone.
6. Create a SPL backup by running ‘spl-backup.bat‘ from SPL-backup-kit folder.
7. Copy ‘sspl-0.91-wings.exe‘ to your cellphone and run it from there. Your cell will reboot and you get the ‘dev mode color screen’. After some time USB will appear on the screen.
8. To make sure everything will work fine, unplug and replug the usb cable. Your PC might want to install the cellphone and if it asks for some driver, use the ‘htcrt_devices.ini‘ file.
9. Now it is time to flash the ‘hardspl-0.91-wings.nbh‘ by running ‘CustomRUU.exe‘ from flash-hardspl-wings folder.
10. Cross fingers 😉
11. OK, if this worked we are now able to upgrade to Windows Mobile 6.1 🙂
12. Run the before mentioned ‘sspl-0.91-wings.exe‘ on your cell. Your mobile will once again reboot and you get the ‘dev mode color screen’ you already know. After some time USB will appear on the screen.
13. Now start ‘ROMUpdateUtility.exe‘ which is located in the RUU_Wings_HTC_WWE_Alcaline_61 folder.
14. If everything goes well, your cellphone reboots and you have done it! Congrats ^^

PS: MAYBE your phone behaves a bit strange after the first start mine did so. Simply reboot again and everything is normal.
