I say superwipe's not the fix because I superwiped, and it didn't fix it. I've said that I superwiped at least twice.

It doesn't make a difference. It's black magic, voodoo, placebo, coincidence, whatever you want to call it. :confused:

Scientific method also demands that you explain the cause. You haven't done that and with my understanding of what a nandroid restore does, there's no reason to think superwipe is the answer if you're going to restore a nandroid. The restore puts back everything you just superwiped, except possibly a few data files on the sdcard that aren't system files and aren't related to GPS. If you could point out exactly why superwipe fixes this, I'd object less to the idea.

Last night I did TEN DIFFERENT SCENARIOS around an approximately 1.25 mile path, but didn't get a chance to share. So here ya go:

I superwiped, then nandroid restored a previous rom where gps didn't work at all. Agps not disabled on this version of ROM.

1) Wifi off. Test drive around the around the block to confirm GPS screwed up again. RESULT: GPS not completely horrible, but has spots of wild wandering.

2) Same phone configuration as above, but walking speed used to test. RESULT GPS horrible, a straight line down the streets looks like a scribbled zig-zag.

Okay, I'm satisfied the GPS is mucked up again, so at this point, I applied the patched gps.conf file, made a nandroid back up, superwiped the phone, restored the nandroid backup just made just as you requested.

3) Drive around the block at normal speeds, wifi off. RESULT: GPS horrible the first half of the drive, it's a zigzag and at least a half block off actual track, the second half, though, it's very accurate. Difference between the two halves of the track was driving speed...first half was residential side streets, speed 25mph, second half major boulevards, speed 35-40mph.

To see if greater speed resulted in more accurate tracks (a point I've made in this thread earlier), I did the same test drive at higher speed.

4) Drive around the block at high speeds, wifi off. RESULT: GPS almost perfect. There's a bit of the infamous wandering at the beginning and end of the track where I had stopped the car. As I thought greater speed produces acceptable tracks.

5) Drive around the block at very slow speeds (<15mph), wifi off. RESULT: GPS inaccurate. Track has about 50% of it showing zigzags off actual track of about 100' in most cases. This particular track might have been acceptable for "Navigation" purposes, but a runner wouldn't find it acceptable for monitoring their run performance.

6) Drive around the block at normal speeds again, wifi off. RESULT: GPS spot on the first 3/4 of the track, but goes to hell the last leg, with an ever-increasing zig-zag effect that ends up more than two blocks off actual position towards the end.

Okay, this pretty much proves to me that superwipe will not fix the phone, even with agps off and wifi off. Are you still not convinced?

However, AHRD 7.0, without the patched gps.conf file to disable agps does appear to give an almost acceptable gps as demonstrated in my last round of tests.

At this point I superwiped the phone and restored the ARHD 7.0 ROM I'd gotten acceptable results with earlier.

7) Drive around the block at normal speeds, wifi OFF. RESULT: PERFECT GPS track, no complaints at all.

8) Jogging speeds around the block, wifi Off: RESULT: ALMOST PERFECT GPS. The track is off actual position on the first leg by about 30', but it's consistent, and the distance recorded is accurate. A runner would find this acceptable.

Now, the final test. Does wifi have to be off, even with ARHD 7.0 installed?

9) Drive around the block at normal speeds, wifi ON. RESULT: GPS goes to hell again. The track is a wild zigzag scrawl across the map with peak location inaccuracies of 3 blocks (1/4 mile). Distance recorded is almost 3x actual driven, speed reported is almost double actual speed driven.

10) Final test, walking speed over a 1.4 mile course, wifi off. This test a couple of hours after the previous nine test. RESULT: GPS not perfect. This time, it took several minutes to get a lock. I didn't wait for a lock to start walking, since my good HOX was already recording my path. By the time the bad HOX decided to start tracking my path, it placed my starting point at 3 blocks from the actual start point, then showed me walking down a street I was never on until it met up with my actual position. From that point on it was a beautiful perfect track. A runner probably wouldn't find this acceptable, but at least the bulk of the data was accurate and might be salvaged for actual distance travelled. For driving navigation software, once it settled down, it would have been acceptable.

I've invested about three hours into all these tests, so I'm just about done with this.

I did numerous tests, including exactly what you wanted (apply patched gps.conf, nandroid, superwipe, nandroid restore), and with a bad ROM, that had no positive impact on the GPS performance. With AHRD 7.0 on the phone without having to patch gps.conf and WiFi off, the GPS performs almost perfectly, but still has sporadic issues.

Now it's your turn...get your phone back on a broken configuration, confirm it's broken, then don't superwipe when you apply the patch. What happens?
