I do have the ST-Link Andreas, read the previous posts please.
What would you have me do next to figure this out??
Can I load bootloader / firmware with st-Link.
What next please!

Hi,
yes, someone with an OVI40 F7 and ST-Link and Windows and STM32-Link should post a screenshot. I currently have no access to my OVI40 F7.
Chuck, meanwhile it would be worth trying "Target"->"Erase Chip" (or simply CTRL+E), it might now do the trick to reset everything to default.

Now I am very confused, are you not reading my previous posts??
I have already used the target erase chip.
After I did that I tried to load the bootloader and all I get is white screen, no LED's

I do read you posts. I know that you did the Erase, which did not work, then you used the "Option Byte" to change read out protection.
And I did not knew that you tried "Chip Erase" after changing the read out protection. If you did, was not clear from your posts...
Anyway, I read the reference manual again (and again) and I would say, there might by no point in actually doing the Chip Erase.
Resetting the option bytes is not part of the "Mass Erase" operation. However, it might be the case that "Chip Erase" does not only do a Mass Erase of the Flash memory, the STM32 Link Utility documentation is not clear on that.
So your best bet is to get the boot address set correctly in the option bytes and all the other settings.

Thanks Danilo,
I do not know how to do that , so I will wait to see if someone posts how.
I do have a laptop that can run linux, so If I had instructions I could use that.

I have searched as well, and see no reference to resetting the vectors.
Is there just a file I can load to do that?

Maybe its a register problem...?!
Some I40 builders faced the same problem here when the MCU somehow scrambled the internal register setting.
Take a look here:
https://www.amateurfunk-sulingen.de/forum/index.php?board=15;action=display;threadid=577;start=315
You should better check the MCU option byte settings with the ST-Link if they have the approriate values like Andreas posted:
https://www.amateurfunk-sulingen.de/forum/index.php?board=15;action=display;threadid=577;start=285
Read Out Protection: Level0
BOR-Level: Level3
IWDG_SW: checked
WWDG_SW: checked
nRST_STOP: checked
nRST_STDBY: checked
FZ_IWDG_STOP: checked
FZ_IWDG_STDBY: checked
nDBOOT: checked
nDBANK: NOT checked
BOOT_ADD0: 0x0080 Boot from 0x200000
BOOT_ADD1: 0x0040 Boot from 0x100000 |

No checkmark set at all "Flash Section Protection" checkboxes !
This should definitely make the DFU mode working again.
Then you need to set jumper P6 and fire up the DFUSe tool again and flash the bootloader and firmware !
Make sure you have the .dfu files here (NOT the .bin !!) for both bootloader and firmware !
That should bring the I40 UI back to life.

I reloaded registers, as listed with St-Link
Jumpered P6, and was able to load bootloader with dfuse
removed P6
Loaded firmware with USB, worked as normal
removed USB, radio came on to boot screen and stayed there.
Unplugged and reconnected power, now when I hit power button, just white screen.
