Question about flash LT 1.91+ with 83850c v1

It's been awhile since I updated, LT 1.1+ was the last time and it seems a few things have changed so I just wanted to check if the firmwares I'm using are correct.

I'm on dash 12626 still so I want to flash back to stock using the LiteOn Phat Pre_13141 orig-83850C.bin file?

The LT 1.91 firmware I would want to use for a 83850c v1 would be the LTPlus-025v1.91.bin?

And lastly, using my old key dump should be fine with updating to LT 1.91?

Thanks for help in advance, the faq seemed to have covered my questions but that's why I'm a noob.

 

That's pretty much right. After flashing with the pre_13141 do the online update so it is then the 025 drive before attempting to flash LTPlus-025v1.91.bin

 

Thanks for the response. I assume that updating via usb with the firmware will suffice? I haven't brought my 360 online for years. lol.

 

usb is better,i find it takes forever when updating online,

 

Thanks all for the help. I really appreciate it.
