This information is not correct. Z4root ver 1.3.0 does work for some people. It worked for me and took all of 15 seconds
I SBF'ed back to 2.3.15, installed the update, installed z4root, pressed perm root and it was done in 15 seconds
it may not work for everyone, but it worked perfectly for me
ota and factory reset and it still does not work with 1.3 or 1.10. was rooted before with another method and updated with root
Its not working for me, ive started a thread here. Cant reroot after 340! - xda-developers
Apparently theres different versions of OTA! Some that root and some that dont!
I don't know if I'm rooted now or not? Was rooted before the OTA via Visionary, OTA went fine, but now can't run wireless tether (which is the only reason I rooted to begin with). When I start z4, my options are temporary root, permanant root or un-root. Which should I try? Also, how can I tell if I'm rooted or not, other than wireless tether?
update: tried running ad free, says it was unable to get root access............. so I guess I'm not rooted, here goes.
Worked for me just fine. No factory reset required or anything else...
Well...I'm not taking the update until I know for sure I can root the second update.
