If FRM cant communicate, how can it flash 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 |

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. |

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. |
