GPS not locking until reboot - post custom rom - Samsung Epic 4G Touch

So I recently installed Calkulin's custom rom v2.9.2 and now my GPS doesn't lock unless I reboot the phone.
Any fix for this? thanks.

Try GPS status app

I have this same problem.. My GPS Status just sits... doesn't find or fix on any satellites.

just tried this, doesn't work on my phone.
Only thing that works is a reboot which is a hassle everytime i need a GPS lock.
anyone else w/ any suggestions? I'd hate to go back to stock ROM.

Doesn't the GPS continue to work for a few days, before requiring a reboot?
Thats the case with my phone, try different versions of the rooted rom, or radios.

This thread is an amazing source for you to spend countless hours troubleshooting this phone's POS GPS unit.
I've been trying countless things on my phone too, I'll let ya know if anything works.

THanks. upon reading a bit of that thread, I found out that through using "GPS Status" I can refresh the "A-GPS" which I didn't know previously.
This seems to work so far.

I'm running the same rom and have no problems with any of my radios, I did also install the EL29 modem when I installed the rom. You may need to try different modems, they work differently on different phones even though you're running the same roms. Also, don't forget to update profile in /settings/about phone/updates

I was originally on EL29 Stock so I'm assuming when I flashed Calks 2.9.2 the modem's the same.
Is there a link where all the modem's can be found? and can I flash any modem?

Caulkin has a list on the same thread as the rom

Flashed the FB21 Modem and this one looks like a winner!
I'm getting instant GPS locks w/o resetting, rebooting, opening an app etc etc.
On top of that, my 3G/4G speeds have increased!
WOW! I've never loved a phone before but I'm starting to have strong feelings for this one.

Cool, maybe I'll try that one too. Don't forget to update your profile

You may want to test drive the fb12 just for the hell of it. I've gotten 9, 12, & 13mbps.
I did get my 1st failed GPS, but it locked shortly after.

I tried the fc05 got 13 then 4G started to sleep in the middle of things. The trick is to find "the one" that's stable and everything works. I'm gonna try the others and see how they work. But I know that this one works for my phone.

Update if anyone's interested: FB21 modem w/ EL29 Kernel was good but still had GPS locking issues. I was getting roughly 85% locks (which isn't bad since I test often). FAST download speeds though.
So this got me thinking: When my phone was stock, GPS worked brilliantly. It wasn't until I installed a custom rom that it started to have problems. The difference was the kernel and modems.
So now I flashed back to EK02 modem and kernel (still running Calks 2.9.2) and my GPS has been locking 100% of the time. PLUS my phone is silky smoooooth!
Crossing my fingers that this will last....

I was in love with EG31 for a while, but, EL16 ended up being better in the long run... EL26 didn't impress me so I didn't keep it for more than a couple hours... But given all of the positive responses I'm flashed it and I'm going to "let it settle" for a few days.
... I'm skeptical that "letting it settle" has any effect, but, it seemed to for EL16. Anyone that has any technical explanation (for or against) would be awesome.

I may be crazy... it could all be in my head or just some luck with the GPS process, but since I put on the EL26 stock rom, kernal, and modem (then rooted) it seems like GPS is much better. Satelites synced in few seconds when outside.
Anyone else? I have not applied any of the GPS fix to the stock EL26 yet, may not need too. Have not done any type of testing other than just using navigation and noticing the faster GPS connection (from GPS being completely off too btw).

The gps app is gps status found in the market.
As far as el26 modem for me it was worse. I used it for 2 days and my speeds were half of what el13 was. I was having worse service and some ghost Los where it just wouldn't connect. Still liking calkulins 2.7 but had to revert my modem back to el13.
I wish Sprint would release an OTA update for this already.

Gps issues

I'm currently running blazer 4.1 with fc07 modem and gunslinger kernel. No matter what Rom I use, gb or ics, as well as testing with different modems, my gps will lock the first couple times but after coming out of a long sleep it won't lock at all. I've tried gps status with no luck, as well as tried the el29 gps fix when I was running that modem. The only thing that seems to work is booting into recovery and clearing cache and dalvik. This will get my gps to lock until my phone goes into another long sleep, then back to nothing. Does anyone know of any other fixes I could try?
Sent from my Blazing fast Epic 4G Touch
Have you cleared AGPS? Also try using a different kernel.
I've tried every combination of everything. I just reboot and that never fails to work. A little annoying, but, no big deal.
I figured it was just a bug in the ICS leaks. Mine also does the same.
Yes, I've reset agps and downloaded through gps status but nothing helps. I'll try a different kernel next, but even when I was on the ics roms and using the stock kernels it would do the same thing.
Sent from my Blazing fast Epic 4G Touch
I had gps lock issues too, but after trying most modems I found one that doesn't seem to have any problems. Make sure you update your profile and prl after flashing modems /kernels

Sounds like u might just have a hardware problem and need a new phone. My first phones GPS was awful and wouldn't lock and my replacement is perfect. Trust me Samsung phones are all different. My epic touch is different than yours and so on. Take it to sprint and get another one.

Never had a problem with a lock on any GB Roms with any kernel or Modem...Ever since I flashed ICS Roms tho...is when it started...None of the (GPS) programs to improve locking would work...The last two leaks for ICS which would be FC06 and FCO7 I've been gettin locks...So its not a hardware problem...One sure way to get it to work is to restore a GB Rom with EL29 get a lock leave GPS Open boot into Recovery and restore a Nandroid Backup for the ICS Rom you were on...Open GPS and you will lock... this worked every time...But now since the last two leaks of the two previous ones I mentioned I haven't had a problem...So its either the Modem or the Kernel...I expect the Modem...The problem is on here a lot of people haven't had locking issues with GPS whether they are on ICS or GB...(Go Figure...)
If your not on ICS its hardware.... I had the same issue till I traded the phone in......new phone GPS works perfect on all GB Roms

My GPS worked at one time, but not at all since ICS, and MAYBE the last two revisions of GB. Tried every trick in the book, even goong back to old modems. Hoping this is addressed on software soon, or I may turn the phone in. Not a dealbreaker, but a huge PITA, I do use it somewhat often. Then there's the principle of a defective product.

I also thought it is not a big deal until I took the bike at 11:30 pm for a ride and (I know this sounds dumb) but I got lost and when I tried to reboot, the battery decreased suddenly from 50 something to only 7%. I had to work my ass as quickly as possible to reach some place I know before it dies completely on me, hahaha...

I have GPS issues on my stock EL29. It was working previously but then I installed the ICS leaks and my GPS stopped working. Went back to complete stock and its still not working. Bummer.
After doing a full wipe and install of the stock rooted el29 tar, I finally got gps to lock successfully multiple times. I left gps locked and flashed blazer 4.1 and all is still good. Do you think its safe to do an advanced restore of data in recovery or should I just restore everything manually?

Anything else? After all I tried, it only gets 2/2 sats after 5+ min
Is anyone by chance using an extended battery? I was for awhile and my gps was horrible. I never seemed to get a lock. I was to the point of being so frustrated that I was going to Sprint to claim a hardware issue. Put the original battery back in and gps locks every time now within seconds. Not sure if the extended battery was truly the cause but idk what else could explain it.

Why not just flash a new modem? I've tried a few different modems and FC24 is the best I've found.

I'm not sure if someone has mentioned it already cause i'm to lazy to check: but Samsung has a temporary fix; type this into the dialer ##gpsclrx## and it should fix it for a couple hours.
If it doesn't work google it because I don't know if phone settings might block it from doing its job.

Modem Issues Since ICS Update

Hey guys,
I was wondering if I can use the EL29 modem with ICS. I have had many issues with ICS and my phone, with the stock ROM and three other custom ROMs. I even had trouble with FH13 and FF18. I had many problems with my GPS not working and I had problems not receiving calls or being able to make calls.
I had to go back to GB in order to get my phone working. Which I like GB but I had to update to ICS to stop getting the annoying update notification.
Anyways, anyone else have this trouble. After talking to Sprint's super nerd tech support, I am 100% positive that my phone just hates anything but EL29.

Thats good to know that I am not the only one. I would run GB still if it wasn't for the OTA update constantly spamming me to upgrade. No matter what I did it was either trying to download all the time killing my battery or it was telling me to install every ten minutes.

3g/cdma no service

Hey guys,
Not sure what to do about this. Unless someone has a better answer, I'm betting that the radio on my phone is dead.
Today, when I left work, I noticed that I was getting a phone signal, but my evdo data wasn't working. Turns out that wimax worked though. But then I ended up someplace where the wimax signal wasn't consistent, so I tried switching back to 3g, but no dice.
So, then I tried booting into the fc09 flashable boot utility to see if I could update profile, etc., but when I did, there was no mobile network at all, and since then I can't get the radio to recognize a signal at all. I have 4 working Sprint phones around the house, but my epic is the only one not working.
So, since I was there anyway, I tried accessing the hash/dialer codes for ##data# and see if I could reset the radio. But, the msl that I had written down for this phone didn't work. When I tried running connectbot to look it up in fc09, it crashed. When I rebooted into cm9, and looked it up there, there was no entry for ril.msl
I guess I could get the msl from sprint and try again. But I thought I would check here for a suggestion from the best community on the planet first. =)

This may sound like it has nothing to do with the modem, but when was the last time you wiped formatted data/ factory reset? I had your issue a while ago, and for some reason formatting data fixed it for me.

Your baseband version is unknown so the only way to fix it is to get the ns4g modem to stick or switch back to the fc09 modem, i use the fc09 modem and it is a lot more stable than the ns4g one, I would reccomend that one. To flash back to it all you need to do is flash a kernel for fc09 and flash the modem in odin and you should be done
