if you look the the comments on driphter you'll see this.

If you have a lower version than that RUU, you should be able to. If your software version is higher then no, you'll have to follow the downgrade guide.

[Q] advice rooting dhd running 2.3.5 and vodafone uk

I'll apologies now if this has been answered but I have not found it.
Im wanting to root my DHD but am confused with all the different options and upgrade this and downgrade that etc. I've read post saying downgrade the radio, install RUU etc but really don’t know what, why or when I need each bit. Below are the versions etc of what im running.
Android 2.3.5
sense 3.0
software 3.13.161.3
kernel 2.6.35.10-g931a37e
baseband 12.65.60.29U_26.14.04.28_M
build 3.13.161.3 CL208029
Which tool is best and how do I know if I need to downgrade, S-OFF (ENG S-OFF) etc
I have seen a post from someone on 2.3.5 and they were told to install RUU
sorry if its all same old but there are some many people say to do it all different ways im confused
Thanks
EDIT: reason for this is poor battery life and was told stock HTC would help or even a none HTC to remove sense would make it loads better. True or not I don't know

No, only AOSP and CM10
I just found this so is it possible when i "upgrade" to 1.09 cause i'm actually on 0.94 so if my carrier supports a 1.09 version i would be able to get s-off? or is this a dead end street to?

ATT to DevEd to WWE??? Just a few simple questions

Hey guys, very easy question today but I can't seem to find an answer anywhere... I'm s-off, super-cid, unlocked, rooted, 3.19 boot, currently running the a converted DevEd from stock AT&T... Most custom ROM's are built on the WWE base... but it has a different model number than I have... 0p6b10000 vs 0p6b12000... Do I need to change my mid to flash the WWE RUU? Does the proper base for a custom ROM even matter as long as my bootloader and firmware are up to date? I mean am I miss out on any features by running a ROM over DevEd vs WWE??? Just curious.
Edit: BTW, I know how to do everything I just asked about.. Just wanting to know if it's beneficial at all
I answered this in the AT&T M8 section.
Please don't make multiple posts asking the same question.
