so after applying this patch, i get like no GPS signal... it's as if it wont even bother trying to connect to a satellite.
running totally stock rom/build/kernel. gps was extremely poor before, now i have nothing.
any recommendations?
I had the same thing .. leave it in a open area with GPS Status open for about 40 mins and then I started to see sat's and got about 12 in total, GPS is working for me much better now but still not stable enough whilst driving .. I'm waiting for my Dongle to arrive.
Also with the rooting ... They have now made a method to root .21 without being unlocked, well you can downgrade and then root in .15 then use OTA rootkeeper to backup and restore root once your back on .21
I rooted on .15 then with OTA Rootkeeper restored root after OTA to .21 and I have installed the patch and it definatly made a improvement... search for my name on this thread and you can see the probs I had and what I did to rectify, sounds similar to yours.
