Installation Instructions are the same:
1) Download, extract to an empty folder. 2) Run
RomUpdateUtility.exe, Have Phone Synced with PC in Windows Mobile 3) follow steps, check device for prompts after PC shows loading bar. it should go to black screen now. 4) SPL flashes, device automatically reboots, job done. 5) to confirm you got it installed, go into bootloader mode (volume down + reset) and verify the screen shows 1.40.

Anyone having problems with the device entering SSPL automatically, please copy SSPLManual.exe to the device and run it. INSTALLING THIS WILL HARD-RESET THE DEVICE
NOTE: this has overwrite protection, so don't try flashing another SPL using hardSPL. if someone needs to revert to stock SPL for warranty reasons, we will soon post a stock SPL downgrade package.
