I had a falcon rgh2 that was all over the place with unreliable random booting (or not at all). It now boots up every time within 30-60 seconds

(thx moco for his insightful Directions/Post)
I made some discoveries last night though that all one has to do to make the right changes to their own NAND smc config was change:
ANA Fuse Value to 03 (Both)
Power Mode to 8480
Power VCS Control to 8555
Leave everything else pretty much the same as mucking around with gain/offset is not a good idea as it is the temp sensor adjustments and is custom for each xbox and has nothing to do with the RGH boot process.
Same as "Backup Data/Value" is exactly that, a backup of the ANA Fuse Value & gain/offset settings
I found that if you change only "ANA Fuse Value" and leave Power Mode & Power VCS Control the same as it was the xbox will RGH Boot but may freeze up or lose controller sync
Moco recommended settings (thx again

)
Program the Cr3- lite with TX's Falconrgh2 timing file
(lk1 short, lk2,3 and 4 all open) and set S2 dips to 2,4,8 and S4 to 4.
Use Slim settings
Important
I also found that most of my other falcon rgh2 mods that I have had done (trouble free install/booting) were already:
ANA Fuse Value 03
Power Mode 8480
Power VCS Control 8555
So if you open your NAND in 360 Flash Dump Tool and find it already at these setting leave them alone
chances are you wont have too much problem getting it booting well with good wiring and the right resister & cap combo
