i need help here. here's my scenario. im using lg g3 d855 with kitkat 4.4.2. i got an OTA notification update to lollipop (v20b SEA), since im rooted i tried to flash this using the lg flash tool with the correct kdz file. i was able to update it to lollipop and everything seems fine; however since i find it pretty big(for dpi) and also not rootable yet, i tried to downgrade again to kitkat (v10k) and it went fine. i was able to root it using purpledrake l, then install twrp to revert back to my nandroid backup. so overall, everything went back to normal.
after 3 days, i decided to go thru to lollipop again
so i did the flashing of the update, but after all of this and during the initial setup, i noticed that mobile network isnt working. i tried to ignore this and just continue to finish the setup. after all is done, and im on the homescreen. i noticed that i dont have the navigation button. also when i tried to switch on the mobile network, it was grayed out. i tried all the possible method of reflashing back this lollipop updte(even redownloading a fresh copy of the kdz file), but to no avail.
question is how to flash back this lollipop update with all functions working?
any help will be much appreciated. sorry for the long story!
