I recommend giving up.
All update files after 4.37.20 are required, and must be updated through each step.
These files are hundreds of gigabytes in size and are scattered.
And even if you update properly, it will take an incredibly long time. At least 1 week?
Crucially, you have to learn exactly how to use ISTA Launchercosole, but it's really difficult.

ISTA launcher console difficult? Thanks, I really needed a hysteric laugh this morning 

But IMHO OP wants to update WHOLE ISTA, not just SDP. For that you will have to buy a license (or a license generator) for offline ISTA from one of the sellers here or on the internet.

1 week? is no problem.
I want understand how to do it by myself, can somebody explain ?

Just download latest full SDP and copy and paste. SDP latest but ISTA old. Like mentioned, need paid solution for whole app update.

Ok, who can sell license for offline ISTA ?

If you are willing to pay, it's easier.
If you are not. You need to know modify msi to install latest ISTA program file, crack program exe and dlls, using Sedoy's standalone to upgrade Data and SDP, BLP.
Not very difficult just Google

These offline ISTA installations can't do programming via ENET, right?

Just download latest full SDP and copy and paste. SDP latest but ISTA old. Like mentioned, need paid solution for whole app update.

Just replace 4.37 SPD with latest and that's it?

You can do ENET programming - you just need to enable in the config.

I just went through the entire process yesterday. Started with Sedoy's last licensed version, 4.37.4x. Following the instructions for ISTA Launcher Console, I was able to progressively upgrade each version until I got to 4.39.2x, I missed the 4.39.21 files and when I tried to update to 4.39.3x, it stopped updating the SDP files. This didn't appear to be an issue because 4.40.10 had the full SDP file so I copied over BMW_ISPI_ISTA_FULL-SDP_4.40.10.istapackage to my download directory instead of the BMW_ISPI_ISTA_DELTA-SDP_4.40.10.istapackage and it upgraded the SDP file. I was assuming that this was the correct procedure. The rest of the deltas ran fine so my installation is up to date to 4.40.5x.

I was originally up to 4.39.2x because that contained the last I-Level from the dealer but when I connected it to the vehicle, I received an error that there was an issue with the programming data and it couldn't do a self test. I decided to start over and see if maybe I did something incorrectly previously. I connected it to the car yesterday after going through the process to 4.40.5x and no errors.
