    I rooted my phone using the description here which worked great. My only problem came when I'm assuming I used SD Maid to clean things up. I used it when on GB and never had any problems. Since I used it my home key does not work and today I don't receive phone calls, just voice mails. I would like to flash back to stock and root again. What is the best way to do this? I read somewhere that doing a factory restore on root will brick the phone, is this true? If so how would I go about doing this?

    Your best bet is to flash the .cab file. Instructions and downloads are found here. Be sure to follow the instructions exactly. This process does have a small risk of bricking your phone. I've done it a few times, neph81 has done it more times than he can probably count. If you do exactly what it says, you'll be fine. Good luck.

    I had to this when going from GB to ICS on my rooted phone before so it shouldn't be a problem. In the link there is only a V6 cab no V7. Is that not yet available?

    I followed the instructions above and everything went as planned. I no longer have root but when it got back to the home screen everything is the same. All my previous apps were still installed. Is this expected or should I now do a factory reset?

    This is normal. The .cab does not overwrite your /data partition. If you are still having issues with your phone, your next step would be to do a data wipe.

    I am rooted ICS (4.0.4) VS920ZV7

    Is the only unroot to flash the cab?

    Do I really care about the update they've been pushing OTA for the last several weeks? I never rooted my wife's Spectrum and she took the update. I haven't noticed that much different about the phone, but I haven't gotten that close to it either . . . (I don't where it's been). :)

    If you take the ZV8 update, it will take away root.

    I figured that I'd lose root, but it won't even take the update . . . not the OTA anyway. I figured I'd unroot, take the update, then reroot.

    Here is the better question, are you rooted or rooted and boot loader unlocked. If you are just rooted, the OTA should go through just fine. If you unlocked your boot loader (IE you have CWM recovery installed), then no, you can not take the OTA. The custom kernel will kick you out of the patch. You're only option at that point is to flash the V8 cab, or really, just flash the V8 baseband as nothing worth while was added to /system.
