I found the solution on my own, and with help from users on the OnePlus.net forums. There is a HUGE oversight in the tear down and screen replacement guides on here involving the possibility of the cellular antenna coming loose from the motherboard. Without knowing it was even there, I simply forgot to check the connection, which was indeed not connected. Here is an illustration to help others (notice the cable for the antenna is the gold connector cable that the tech is pointing to with the spudger(sp?): https://d3nevzfk7ii3be.cloudfront.net/ig... Hope this helps others.
I appreciate the replies but the fact remains that my phone wasnt jailbroken when the recovery loop started so i dont think saving shsh blobs is an option--correct? @Puckettj4, what does "reflow my chip" mean? Also how do i restore from TinyUmbrella? I understand how to fix recovery and exit recovery but im not quite sure how you would restore with TU. Thanks again for your comments!
My fix was much more low tech...my iPhone apparently had acquired a righteous among of belly button lint in the screen for the mic. I used an old dry toothbrush and gently cleaned out the area and it looks and more importantly, works like new. Sometimes you gotta go low tech first... Anyway, here the picture showing the location. Basically the standoff is a screw that holds the board to the frame and has a head with an opening to screw into, in this case the cover over all the ribbon connectors has a screw holding it down received by the standoff. http://cl.ly/3g1Z401o0M3G3l2o3a3V
There has to be more involved with this rather than simply screwing in a screw at the top of the EMI for this to be resolved. It would be nice to hear from the OP in regards to results... I, too, disassembled my phone and noticed that I don't have the silver grommet on the plate where the longer screw goes in, so I'm assuming it came off without my knowledge in the teardown/reassembly process. I ordered a new part to see if this would be a fix. I don't understand why all of the parts dealers, this site included, are identifying the part attached to the speaker as the WIFI antenna if this top location is actually for wifi then. Seems like a new one would fix this issue, but it does not. Your link doesn't show two screws, Jeremy. It just shows the assumed location of a gold connector and a "likely" 2.4 GHz connector pad...Tells me nothing. Not trying to be a troll, just frustrated by the lack of completeness on repair sites. Seems like the OPs never bother posting results after someone marks the issue as...
