after i had updated some stuff i was in the dreaded boot....wait....
after many hours of hunting through the web and doing many tryouts... this is (at least from my view) the easiest:
goo DOT gl/ptwTAV
shorturl, leading to lenovo-ru forum with clicky for stockroom for the x30F. they also have the files for x30L or whatever you have in various versions^^
there you can login using google+ to download that file. it has the stockrom+tools needed to flash it.
download, extract
i also found a working recovery-image. what i did was simply overwriting the recovery.img found in the extracted archive . i uploaded it because i lost track from where i got what image, and most where very buggy.
alturl Dot com/nt2eo
shorturl,leading to zippyshare
<--grab file, put into folder where you put the extracted stockrom from the russian site.
install/run qfil to flash it (click through it, you basically only have one option at a time, bit reading is all you need
)
with the recovery i was able to succesfully flash supersu from the chainfire site. got root, rebooted.. survived, playstore, luckypatcher,titanium backup.. all the yada.. rebooted.. integrated most updated... survived... works fine for now :]
i know on the official russian site is a newer stockrom... 6.0.1 but from there i was unable to root, do stuff.... be happy. so iam using the 5.1.1 works nicely, doesnt bug me that much and i can do stuff.
xposed ...so far lesser luck. i think i reflashed my 5.1.1 about 6 times in the night :->
so iam happy i got superuser and most of my stuff working
i remember flashfire didnt work, but didnt mess me up, maybe thats working now, too
enjoy :->
edit: xposed now runs fine,too
problem was the SELINUX thingy in enforced mode. you need to get it to PERMISSIVE. i dont find the exact page anymore, but there is somewhere in here something called "permission changer".. that you dont want. there is one init-d. thing, that you want.. but not as init-d thing. there is a "doesnt need init-d to do it" that is the thing that worked for me. the init-d version should work, too but i had trouble with "universal init-d enabler" or^so, it only closed without a message. installed an "init-d toggler" that supposedly works, but the selinux thingy doesnt needs that. you should be fine with either approach (except the app permission changer approach, because its not "early enough" in the boot process )
