Root process failing halfway through script execution - Sprint HTC EVO 4G LTE

So I rooted my Evo successfully as well as the Evo of one of my good friends. However, a second friend of mine wanted his new Evo rooted so I naturally obliged. However, his phone repeatedly gave me the finger when I tried to root it. Here is what happened:
1. Executed root script via THIS METHOD
2. Script began rooting.
3. Script entered first phone restart phase.
4. Script entered second phone restart phase.
5. When phone turned back on my laptop no longer recognized he device (i.e. Android 1.0 in Device Manager) and so the script could not continue its process.
My attempted solutions:
1. Reset to factory settings and reattempt to root. (Failed)
2. Reset to factory settings and attempted to root using RegawMOD (Failed)
3. Did not try to RUU as I did not have the RUU necessary for his device.
My question here is this....if I RUU his device and reattempt the root is it likely that I will encounter the same issue as I did initially? I do not know whether this was an issue of the rooting process or an issue with the drivers on my laptop. My powers of deduction tell me it is based within the phone since immediately after his phone was unrecognized I was able to plug my phone in, as well as my other friend's Evo, and have my laptop recognize both devices instantly.
Cliff Notes:
My Evo: Rooted Successfully
Friend #1's Evo: Rooted Successfully
Friend #2's Evo: Root Unsuccessful

Personally I would just HTCDev unlock his phone and flash TWRP...then download whatever rom (even the rooted stock if he wants to stay 100% stock) and flash it. Best way to root imho. Hasn't failed me yet!

RagawMOD root uses the htcDev method. It failed as I stated in the original post.

I updated my drivers like 10 times. Plus, like I said, my phone a well as my other friend's phone works just fine.

If you have the most up to date drivers in device manager it will show "my htc" not android 1.0.

Interesting. It definitely sounds like Drivers. The quote below me is right on. I was having this problem as well. The only thing I can think of is that you have a couple sets of drivers on your computer. When you go to update it updates with the old drivers (don't know why). I had this issue with my Kindle Fire.
Have you tried to update the drivers by manually selecting where to find the drivers?

I guess I should've added that to the OP. Part of my fix prices was also to completely uninstall all HTC drivers and reinstall them. I used the drivers from PDANet since those were the only ones that managed to work correctly. All of the others wouldn't install correctly.
