I have installed the Kernel SpeedMod K9A on my Galaxy S.
The GPS receipt is complete down, I think in the beginning with the speed Kernel (i1-2) the GPS receipt was fine.
The LBSTestMode show under „Get position test“
DOE: 1 Azimuth: xxx
System: 11:53:52 on in 2010-11-27
Elapsed (Sat): X.xxx (second)
No Satellites are found.
If I wipe the phone, the receipt is again fine.
Then the LBSTestMode indicates no entry DOE.
If I Recovery my Data back via Restore Mode, the error appears again.
I already try JI6, I followed "xda-developers - View Single Post - GPS still not working after JI6 Update- Please help", I used FasterFix for Europe settings in gps.conf- nothing.
Can anybody help me without: “so, make a wipe”
weird , i also installed K9A and didn't wipe a phone but the GPS work fine.
i use DXJPA.

Like this comment, my GPS works fine using DXJPA+K9.
SpeedMod lagfix and GPS performance.
Old thread but I just found it while searching for information on the issue I will describe below. Maybe this has already been addressed elsewhere and if so I apologize but I could not find info on this anywhere.
It has to do with SpeedMod Kernel, the lagfix options and GPS performance.
I am running on Doc’s 9.6.6 ROM, XFJS5, JPY modem.
Until yesterday I had SpeedMod 13KA with the tweaks (first 4 enabled) and lagfix (first 3 on ext4 the loop ones on ext2; no system conversion and Bind_data=false). My GPS reception was horrible – loooong times to lock and very inaccurate, jumping all around the map, lagging behind and loosing signal easily.
Yesterday I swiched to SpeedMod K13B, I enabled the tweaks and default lagfix but without touching DATA_LOOP, CACHE_LOOP & DBDATA_LOOP settings. These remained “=false”. My GPS performance improved miraculously! Lock in fewer than 10 seconds, accuracy 5-10 meters.
This morning I put data_loop, cache_loop and dbdata_loop on EXT2. GPS performance was terrible again. I used GPS Test and I could only find 1 (one!) satellite in over a minute of waiting under open, clear sky. I then disabled all the LOOPs again (all “=false”), and behold! I could find 7 satellites in less than 10 second, locked on 6 of them in 12 seconds and on the 7th in less than 20 seconds. Accuracy was 5 meters.
Do you know why this happens?
Today I installed the K13E version on my stock Froyo 2.2.1 device and I have the exact same problem:
The GPS device will just find 1 satelite and no fix. I have only replaced the stock kernel (J5) and haven't applied any lag fixes yet.
Does anyone perhaps know of a fix for this? Could anyone maybe explain how and where to set the abovementioned changes?
Many thanks in advance!
Maybe it is hardware related. Try this?

After I switched to Darkcore kernel my gps works again...

Please post your GPS Lock Speeds (how long it takes approx. to get a lock) and how accurate (meters).
In addition, i would love it if you could post what ROM you are on, and any fixes you have used.
I have been ROM hopping and trying various settings and things. IF I ever do get GPS signal in GPS Test, it's never more than 2 Satellites, and that's like after 2 minutes. And I have only ONCE had Google Maps actually accurately keep track of my location.
Last question, when I ODIN Back to the original AT/T Stock, does the ENTIRE phone get reset? Modem, baseband, GPS firmware, etc? Cuz on both stock 2.1 and 2.2 i cannot get ANY LOCK EVEN IF I LEAVE IT FOR 10 minutes.
My main concern is GPS, I want a good lock, within 10, even 20 meters is okay, I have seen it done on YouTube before. I don't care so much about speed and battery meh. Anybody have good ROMS that have a high success rate of GPS lock-age? Again, once upon a time on like 1 ROM i got good GPS, since then, no luck. I have tried all the fixes on the internet / settings changes, etc.
i get a lock withing 20 seconds with 15 (often)-5 (rare) meter accuracy. running 2.2 i9000 froyo rom with jk3 modemand setiron kernel
Iget a lock within 10 seconds with 5-10 meters accuracy. Tracking is e excellent too. I got this by using the JM9 GPS files. I posted a lot about this in the Axura thread. Check it out. Hans is actually using it in his next release as I did extensive testing with only positive results.

i currently live in sao paulo - brazil.
my lock times take 30-60seconds, but after locked it just stays on 5-10m
but i´m happy with that.
how do I check my gps speed?
As a heavy GPS user for driving navigation and sports tracking, using EndomondoPro, I can't afford to have a broken GPS. When my Exhibit II was unrooted and stock, I had occasional GPS troubles in which the GPS would not lock into a signal and whatever app I was using showed that it was still searching for GPS. This continued when I rooted the phone but kept the ROM otherwise stock. Same when I tried CM10, same with the first Slimbean 4.whatever and then with the latest Slimbean 4.2.2. Most of the time it would work, but sometimes not. I added the app PimpMyROM and tried the tweak that is supposed to improve the GPS, by indicating that I'm in North America and the United States. The app then supposedly downloads a GPS config file.
Upon loading the Nexus ROM, I was sorry to find out that GPS doesn't work at all. So I restored a nandroid of the latest Slimbean ROM. I rebooted, and found out that GPS was not working. The app GPSTest showed a handful of satellites in view and working, but no speed readout (I was walking). EndomondoPro app, which uses GPS to track sports mileage/speed showed the ?Locating message in the lower left of the screen, and would never lock onto the satellites. The GPS icon in the status bar -- the white bullseye -- kept blinking, indicating no lock on the satellites. I rebooted the phone, turned GPS on and off, rebooted again, and it still didn't work.
Then, I tried the tweak for GPS on PimpMyROM, and BOOM! The GPS worked.
Is this coincidence, or proof that there is some benefit to using that PimpMyROM tweak? Can any devloper explain what that tweak does, and why it is necessary and not already built into each of these custom ROMs?
And finally, since GPS is very important to me, does anybody know of a custom ROM that is optimized specifically to give all power and glory to the GPS function of the phone? If so, that might be the custom ROM for me.
I have also wondered about the pimp my rom tweaks. Like how does it give you better camera quality?

It installs bravia engine or something like that which has been debunked before. A lot of tweaks are placebo effects. Its kind of like having a quad core phone. Everyone says its faster but for everyday use not so much. All 4 cores will only kick on when the phone is under a heavy load like running a benchmark. This is why I'll prob get another s3 instead of getting an s4 don't see the point in a quad core phone

After flashing the AOIP rom, I find that my GPS apps find the GPS signal super fast. On Slimbean, it was taking FOREVER for my Endomondo app to find the GPS signal. For those of you who use GPS frequently, if you're having trouble with other ROMs taking a long time to lock in the GPS signal, try AOIP. Not sure if my experience is unique to my phone or geographic location, but the improvement for me is HUGE.
I have to agree. I have used almost all of the roms posted in this forum. AOIP is by far the best and my fav. Rootbox comes in second and PACMan third. As for the GPS, it really does lock on fast. I play Ingress, and it took what seemed like forever to get a lock. Now it's within a second or two.
I have a fast gps lock to, im wondering if it's because aoip was built for our phone and not a port has something to do with it

Has anyone noticed if the time for GPS fix varies by ROM?
I'm not sure if I'm imagining it, but I remember 9.1.A.1.140 being a lot quicker to get a fix than most of the ROMs I've tried recently
CM11 feels quite quick, 1-3 minutes, AOKP never got a fix for me
Lovin's .210 and steveboss deodex .210 takes around 5-10 mins
I've yet to try Carbon or OmniROM
Do the programs requesting the GPS fix make a difference? Google Maps and Endomondo sports seem much quicker in comparison to Ingress to get a fix
You need several minutes to get GPS signal?
Either you're in a building and not under clear sky or sth. is VERY wrong with your device.... under clear sky there shouldn't be ANY problem and a signal within a bunch of seconds. I'm using 4.3 version .210, before that CM 10.2, before that 4.1 stock... no problem at all; my navigation app never needed more than 10 seconds to get my position (in the car).
Yep, last night it took over 15 minutes to get the first fix in an open area, with overcast clouds
I used AndroiTS GPS Test, and it seems to get GLONASS sats, but never uses them. Then after 5-10 min, the normal GPS sats kick in.
I'll try reflashing a wiping again, see if that helps.
Logcat seems full of LocSvc_adapter and LocSvc_eng errors
