Thank you! I definitely see an improvement in lock time.

Working so far here. Flashed it yesterday and after a deep sleep last night it fired right up this morning. Inside it doesnt lock on very well, but then again I dont need GPS inside my house lol.

Left GPS on for 5 minutes with no lock on stock ics modem. Rebooted and flashed-lock in under 10 seconds.

Sorry if this seems like a stupid question.

To flash this with Odin, does my phone need to be rooted? Im assuming so, given the command line commands in the linked thread.

If so, is there a way to still flash the radio without rooting, and retaining warranty?

Thanks.

This did not work for me, it seemed to work for a day, then back to the same old,no locks, or lock in 20 minutes.

Went back to GB, now it works fine.

Check GPS.conf first, before flashing anything.

No matter what I did, GPS simply wouldn't work. Flashing back to stock, re-flashing several ICS ROM's with complete wipes of the phone including EMMC and SD card did nothing. The last AT&T leak, as well as the official did nothing to fix the problem. As soon as I flashed back to sauROM or any gingerbread ROM, GPS would start working perfect, with 6 second lock, but back to ICS and GPS would quit again. Last week I finally found and fixed the problem. I flashed the radio from the gingerbread bread ROM on several ICS ROM's including the new official, and it's worked perfect for the last week. The UCLF5 leak and the New official AT&T ROM. I'm running Flapjaxxx ROM with no issues. GPS locks in under 10 seconds, LTE here in Tampa, FL signal strength is the same as is LTE giving me 21MB down and 12MB up, on this UCLA1 radio. Just because it's an older radio, doesn't mean performance is effected.

Flash with Odin (I'm using v1.85) Don't unzip/extract and place it in the phone space, NOT PDA
Make sure phone is in download mode and you have the samsung USB drivers installed.

First thing I did when I experienced the GPS issues after updating to official AT&T ICS rom is check the GPS.Conf file. It was a total mess. So I used tthis one instead. After a reboot, I got locked in less than 10 seconds. Just put it in your /etc/ folder and take out the.txt at the end of the name.

Report back to see if it fixed your issues.

I flashed this and it still won't lock, any suggestions?

I'm not seeing the /etc/ folder; to access it would I need to be rooted?

This had no effect for me. I replaced the existing file using root explorer, mounted back as R/O, rebooted and still can't get a fix. Only way I can get any sort of location based anything is using cell towers. It has been that way since upgrading to ICS, has only worked a handful of times.

how do you do this, can you provode links or instructions please?
