If you look in the WinKFP Data folder you will see that for an FRM it only programs a program. no NAAB, no data. WinKFP (or NFS emergency flash) or ISTA only touches the P-flash. What happens when an FRM goes haywire is the EEEPROM partition on the D-flash get's corrupted to the point where the module does not communicate anymore.
Emergency flash would be useless since the module does not respond to any diagnostic commands. If it is accessible then flashing would not rectify the problematic EEP.
Only way is to do it the easy "hard" way, soldering those 4 wires on, reading the d-flash, convert it to EEP, write partition division so EEP is at its largest and then write your converted EEP. From my experience it will fix about 80% of all faulty FRM's that i worked on.
If you're experienced at soldering you'll have the wires soldered on in under a minute. one of the easiest soldering jobs to do really

I agree with You. So I don't understand why someone succested to use emergency at all.
I assume the pinpoints in PCB in FRM3 are allway in the same place. It would be nice if someone could develop jig for FRM3 makeing soldring unnecessary
I got this one: https://www.kremersino.com/de/shop/76-testing-fixture-for-bmw-frm-.html
Works perfectly as long as you are the first one recovering the FRM. FRM3 Fixed in 3 minutes once you have it in your hands! If there is already soldering tin on the pads, it won't work.

Soldering is one method and buying that pin adapter is great if you do large numbers. I take some children’s play-doh (has to be fresh) solder the edges of the wires and use the play-doh to hold the wire on the point. On some FRM’s (mostly I’ve seen on E7X) you have to scrap off the protective coating. Takes me maybe 3min to setup.
