That's hardly the best option since it's unreliable and devmode rxTools is much easier to boot and use.
In any case, I wish OP good luck
I agree that pbt-cfw is a pain ever since other cfw came out. However, like I recommended in those update
tutorials it should give steps separately for both 4.x systems and those above 4.x. For instance, for 4.x systems that want 9.2 I really recommend pasta cfw with nop90 mset POC. That way no one will ever have issues with updating that way as there is no catch on what mode to use. From my perspective it is easier for those who are doing it the first time as you can predict that most will not read fully like the OP has truthfully said he didn't.
So to sum up, I recommend for 4.x:
1) Use Pasta cfw with nop90 mset POC
2) Use sysupdater .3
I have always used .3 and will continue to do so even if future versions come out. Since sysupdater is being used for updating sysnand in these cases why not use the guaranteed version that was working prior to that brickfest of the beta one.
