Never touch a running system. :/
I just did this on my DHD and I'm getting a 10 satellite fix in my room! That's never happened before. I used to catch satellites only when I stood in my balcony or next to my window, that too after quite a long time. Big thanks to rakesh2002 for this guide. Anyone who's having a GPS problem that doesn't improve no matter what they try on the software side, I advise them to try this out. It's the only sure shot way to fix it. I knew for sure it was a hardware problem on my DHD, because I used to get a crappy 3-6 satellite fix even when driving, but when I lightly pressed and held down on the GPS antenna cover, it immediately jumped to 10 satellites or more and went back to 2-6 satellites once I released the cover. Try this out first with your DHD to check if the hardware is at fault. If you're getting a good satellite fix normally, then no problem. Also, if you're scared of doing this, an alternative is to get a tight fitting silicone/hard case for the phone and putting that on when you want to use GPS (if you don't like using cases for regular use). The case will press down on the GPS antenna cover and give you a good satellite lock. I used to use a silicone case and never had a problem with GPS for more than a year since I got the DHD. I started experiencing problems only after I stopped using the case because it looked like crap.
Point to note - The bottom of the antenna cover has a strange clip. It's just a plastic projection unlike the standard clips on the top and right side. It's quite hard to put back into the phone because you can't just press it in like the other clips. You'll want to be careful with this to avoid breaking it. Mine broke as I was prying open the cover itself and is sort of dangling in its place now. I put it back into place and stuck it with super glue, but I was unable to put the cover back into the phone without breaking it again. So I gave up and just let it be. But it doesn't affect the result at all. I bent my spring contacts upward and even with this clip broken and the GPS antenna cover subsequently not having a tight fit at the bottom, I'm still getting a perfect 8-10 satellite fix in my room.
I'm sorry but I can't believe this is a hardware issue. In my view, the GPS problem is a software issue.
Let me tell you about my HTC Desire HD. Google navigation worked fine on the stock ROM. I then decided to root it and to put CyanogenMod 7.xxx onto it. That's when my gps problems started. I would get a lock on very quickly but then it would hunt for satellites after about a minute.
I tried all sorts of solutions, none of which worked. I then put the stock ROM back on and the GPS worked flawlessly.
After a while I thought I'd try an experiment with an ICS ROM. I tried MIUI, Virtuous and PrimoS and the same GPS problem came back with all of them.
