can't root phone after sbfing to stock 2.3.4

[christianstudebaker]

I need help, I was running cyanogen mod 9 and my phone doesn't have the power to run it so I wanted to go back to cyanogen 7 so I sbf'd to stock and now it won't let me root, when I try to run system recovery a message pops up saying: "error running exec(). Command:[su, -c. Data/data/com. Tenfar.a4. Recovery/files/surunner.sh] working directory:null environment:null"
If anyone knows what this means please let me know

I don't know what that means, but I do know that the latest stock version (.615 I believe?) isn't rootable and it took some real trickery to get it back... something like .sbf'ing to a euro build, then flashing a ROM. The radios are mixed in there somewhere, too. Obviously my memory on it all is very fuzzy.

If anyone could give me clear directions on how old start from scratch or where to go from here it would be much appreciated

[jntdroid]

are you on .615?

[christianstudebaker]

i am on 2.3.5

menu/settings/about phone/ system version 1.3.418?
use magic md5 root

edit: [QUOTEI wanted to go back to cyanogen 7][/QUOTE]
cm7 only works on 2.3.4
only rom for 2.3.5/1.3.418 is eclipse

if you still want cm7, use 2.3.4 sbf, root with pete's root tools

[christianstudebaker]

it is .418

Thankyou themib for the help. I successfully rooted it and am happily running cyanogen 7
