hi tommer2,hopefully you havent damaged the file system of your phone beyond repair by flashing the recovery for a completely different model. if im understanding correctly,your phone still boots,wich is a good sign
you can use this recovery for sensation:
PG58IMGcw5.0.2.0.zip
md5: PG58IMGcw5.0.2.0.zip
9e4b4858f75231d0ff45a45acaeb7ac7
it is a PG58IMG file,so you can rename it to only "PG58IMG" (no quotes),place it on your sd card, and let hboot flash it for you,or you can extract it,and place the image in your adb/fastboot folder and flash it they way you have been flashing the other,
fastboot flash recovery recovery.img
make sure to remove the old recovery image first,and let this experience teach you a valuable lesson of being extremely cautious what you flash to an unlocked/s-off phone.
as you have learned,your bootloader is not doing any security checks,and it will happily flash anything you tell it to. you are prolly fine and will suffer no irrepairable damage,but if you had flashed a bootloader or radio from another device to your sensation,it would be a different story
in the future,make sure you always:
1)ensure youre flashing an image or file for htc sensation,and not for other models
2)double check the md5 to ensure you have a good download.
also feel free to post up any further questions you have in the sensation 4g forum:
