Cannot start Macbook Pro 15,2

Hello everyone

I apparently made a mistake on a Macbook Pro late 2019 (15.2)

I installed OCLP and made an install key for a MacBook Pro (15-inch, 2017 14.3) to install Sequoia. No problem so far

I patch the USB key for this model and the EFI of this key for this 14.3 model, and then I close everything to go and install Sequoia on the target Mac. The problem is that my Macbook Pro 2019 no longer starts now... error message when booting with request for after-sales service...

It starts in recovery mode, I launch the disk utility to do the basic checks, everything is OK, but it still does not start on its Sonoma OS...

I looked with the terminal in the EFI partition if I had not installed OCLP on the wrong partition, but this partition only contains an Apple folder...

I am lost and going around in circles, how can I simply restart this system in the Sonoma version installed, knowing that I do not have the space on it to try a Sequoia update from a system key? for the record, this macbook pro 2019 is compatible with Sequoia without OCLP.

Any ideas or leads to solve this problem?

thanks in advance
