    My OP2 has a bluetooth call quality issue and I have decided to return back to 2.1.1 to see if the problem persisted there as well. (issue described here)

    I am currently on Stock unrooted 2.1.2 and wish to return to stock 2.1.1. Is the below mentioned method correct ?

    Use a 2.1.1 signed flash zips posted here
    Wipe data, cache, dalvik cache, format... (I am okay with loosing data as I have backed up everything)
    Install ZIP
    Wipe cache, dalvik cache...

    I too am interested in this procedure. If one does this will they lose OTA updates?
