What exactly is that so-called "recovery patch" you used? If it's anything other than a properly made Cure firmware meant specifically for the dezl 770 including using the correct HWID as mentioned in above post, then you best give more info and a link to it. Note that flashing random files might make the initial problem even worse.

You can check the device's [Only registered and activated users can see links. ] several ways, even if it's soft-bricked because [Only registered and activated users can see links. ] should still be available.

Be aware that even if you flash the proper Cure firmware to it, it will still remain stuck on the Logo splash screen because the sole purpose of cure fw is to stall the boot process before faulty files are loaded thus re-enabling Mass Storage Mode so that such files can be removed. If a device has become bricked for some other reason, e.g. a wrong firmware has been flashed, then a different recovery method is required so you'll need to say exactly what you did along with linking it.
