ok, so you got it finally 
this post deals with hardspl, the next one will deal with ROMs
Features:
- this is unsigned Hard-SPL and ignores CID too, so custom roms or dumped & reconstucted roms (and any htc rom update) can flash. but it enforces ATHE400 modelid (I patched it for that). so ATHE***** or ATHE100 roms will be rejected. ATHE400 or ATHE400** is accepted.
- also, this has SPL overwrite protection, so won't accidentally get overwritten. but if someone needs to revert to stock SPL for warranty reasons, a stock SPL downgrade package is also available here.
- if your x7510 gets stuck on booting OS, then I have another way to revert to stock SPL in the cases when warranty is needed, this is a new special feature of the overwrite protection!
Requirements:
- first, if you have x7500 or x7501, then do not flash this.
- to download a compatible hardspl package for x7500/x7501 go to the other Athena subforums.
- also, make sure you have .NET framework installed on your PC! if not, get it from http://www.microsoft.com/downloads/d...DisplayLang=en
- finally, if you have vista, WMDC update is recommended: http://www.microsoft.com/windowsmobile/en-us/help/synchronize/device-center.mspx
Instructions:
1) download Hard-SPL package from attachment, extract to an empty folder.
2) you must Have Phone Synced with PC in Windows Mobile!
3) run x7510_HSPL365.exe
4) follow steps in the RUU, and check on the device for prompts after PC shows loading bar.
5) it should go to tricolour screen now and say 3.05-OliNex (3.05 is for SSPL version, the original SPL is 3.05.0000)
6) SPL flashes, device automatically reboots, job done.
7) to confirm you got it installed, go into bootloader mode (tricolour screen!) and verify the screen shows 3.65-OliNex (3.65 is for Hard-SPL version, the original SPL is 3.05.0000).
NOTE: you will not see the SPL version during normal boot, that is the OS version, not SPL!
to enter bootloader mode to see version: with the device turned on, press and hold the camera button (ALL THE WAY IN) then press the reset button with the stylus tip, then release the camera button when bootloader tricolour screen appears.
NOTE 2: anyone having problems with the device entering SSPL automatically, please copy SSPL-Manual-x7510.exe from the SSPL-Manual-x7510.zip attachment to the device and run it. then once the screen is in SSPL, run RUU manually. i.e. you run the RUU on the PC, if it isn't obvious.
NOTE 3: do not use this RUU to flash anything else! this is only intended for flashing SPL's.
NOTE 4: flash stock SPL *only* if you need to return the phone for warranty. only use it as last step - after reflashing stock OS and radio. usage: run the hardspl exe but do not press Next yet then replace the RUU_Signed.NBH with the stock spl NBH (posted here too), then go flash.
