[FIX][GPS][CONFIRMED] Fix for no GPS lock after Froyo flash

This is based on the post by SINN, as well as the method I, and many others have used to get mine working. Okay, Let's go do this...

Method 1 (Do First):
1) Start from a DI18 ROM/Modem with WORKING GPS
2) ODIN in DK28 Modem
3) Restart and verify GPS lock in DI18 ROM + DK28 Modem - It could take a minute or two
3a) If this step fails go to method 2
4) Flash a DK28 ROM, verify GPS lock

Method 2 (Long Way Home):
1) Start with stock DI18 + working GPS
2) ODIN in modem
3) Restart and verify GPS functionality with DI18 ROM + DK28 GPS
2) ODIN in DK28 full
3) Restart and reverify gps lock
3a) If this step fails, take a nap, and return to step 1)
4) Reroot and flash in new DK28 based ROM
5) Reverify GPS lock

Ya. I confirm this aswell. Dk28 rebroke ma gps. Doing those steps fixed it. And still working 3 days later.

Thanks the gps fix worked like a champ!!!!

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

wow thanks a lot.. got it accurate to 2 meters.

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

I found another way of doing this too. I can confirm that this works.

"Fixing the GPS no fix issue on the Samsung Epic 4g requires you to do a manufacturer's reset by obtaining the MSL code from Sprint. Once you get the MSL Code, remove the SD Card and Enter ##786# on the dialer keypad. You will see two options: View and Reset. Tap on the Reset option and you will get a prompt to enter the MSL code. At this point you will be asked if you want to do a manufacter's reset, enter yes. The phone will shut down and reset itself after a few seconds. Once the process is complete, the phone will go through a hands free activation. After the activation process, updates may be downloaded and installed. Now that all updates have been performed, you may check to see if your GPS is working by going to Google Maps. You should be able to lock in GPS signal in under 10 seconds. Thats it. Your GPS woes are over."


Actually it didn't automatically activate for me, I went into SprintZone and it did it from there.

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

from dk28 "froyo" you did this?

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

Yup, I called Sprint and got my MSL, went thru the steps and got a 10 sec lock on Sprint nav.

EDIT: I had to odin earlier and the automatic activation did go through when I tried it again. In fact it's way easier for DK28 doing it this way.

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

cool, just wanted people to know they can do this on dk28.

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

My GPS locks fine, but while driving it loses the signal every couple of minutes. Any idea?

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

i got a little more info on this, if you call sprint tech they can do this for you ota. dont call them from phone or on pc use chat on sprints site. i just talked to my sprint guy and we did it on a store epic that i flashed dk28 rom on first.

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

+1 on the ##786# method...afterwards, gps locked in like 5-8 seconds
thx guys

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

also that will stick after you flash another custom froyo rom.

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

i was wondering if i had to do that after every flash...thx D1

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

Plus one here. I also have the issue. I know I read somewhere in fixing it but can't find the thread. Any ideas guys?

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

Are you using Google Maps?

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

Here is the solution that fixed this for me:
Im trying this fix below for the disconnects. Hopefully it works.


Go to /data/gps

Remove secgps.conf

The file gets recreated when you use an app that requires gps. I have not had an issue with the gps losing signal since making this change.

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

Reflashed to the latest midNIGHT ROM and so far so good.

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

first thing, GPS works fine as far as acquiring a signal lock, BUT does any1 else notice this:
when epic is stock(never rooted or anything) compass mode in street view on google maps works perfect.(also tried it on an Evo, worked fine) meaning when u search for a location(address) u can tap the address and in compass mode u can spin 360 degrees and what u see will rotate with u perfectly.
ever since i went custom, compass mode in street view on google maps always shows the camera view straight into the sky and can never get it to view straight in front of me. is this sumthin new?? can it be corrected?? i reported the image to google, but jus got the regular BS email, "thank you for telling us.....we're looking into this.....thank you, come again" is this sumthin new?? or can it be corrected?? TIA

add-on: tested on Epic experience rom/supernova rom/nebula rom...same result unfortunately

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

Hope this thread is not dead.... I am Gingerbread and not rooted. after OTA upgrade to Gingerbread, my GPS only locks on 2 to 4 bars the rest are grey and when I lose my bars (all are grey) the lock is gone till I soft reset. Any ideas or help?

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

2-4 cellphone bars? have you tried GPS Status app?

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

Just about all of the rooted custom GB rom options have the GPS fix baked in. Plus lots of other cool stuff that will keep your Epic from getting old. Might be worth looking into. If I could do it with my geekless DNA, probably anybody can.

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

Can you still use Z4Root??? or does this not work in gingerbread? Does this break the warranty?

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

PS, GPS Doctor seem to work best... but still not perfect... any fix out there without rooting?

Re: [GUIDE] Fix for no GPS lock after Froyo flash
 

Z4Root was never updated after Froyo. NG for GB.
Yes, rooting breaks the warranty. But you have the option of reverting back to stock (if you learn how) if you ever need a warranty replacement for a hardware issue.
Don't know if there's a no-root fix or not.
