[Epic 4G Android Development] Stoney60:
You are exactly correct! It's what I've been saying ever since I flashed the update.zip that destroyed a previously working GPS. The problem is doing this method doesn't install the DK28 modem. Doing an odin back to DI18 stock woll of course fix the problem so you can get a lock which is absolutely irrelevant if you still want 2.2. You MUST Odin the full tar of DK28 to get the DK 28 modem installed which will result in a working GPS.
[Epic 4G Android Development] Stoney60:
Well, you CAN flash the update.zip DK28 in recovery. Which, it seems to me, will result in a screwed up GPS again. Wiping does absolutely nothing for you IF you Odin the full .tar file to flash.
[Epic 4G Android Development] justpastfinish:
Do you guys think we could odin to 18.....then flash dk28 modem, then do a nandroid restore of a dk28 build? That would save me from restoring all my settings an stuff...

YES GOT FROYO... hey wait but no gps!!! pfffft wtf

****ing epic 4g is starting to piss me off. ive had nuttin but problems with this POS phone. Now that i have flashed to froyo. i have no gps. and i dont quite understand this way to fix it. So im going to spend buncha time i dont got to get this pos gps working. DONT BUY A EPIC, AND DEF DONT UPDATE TO FROYO YET. ****ing sprint/samsung needs fix this ****. I paid allot money for this phone that i wish i didnt. i hate to talk bad about stuff and i rarely do, but i mean cmon. WTF is with this ****ty gps crap. and why does my cheap ass LG touch phone gps work instantly and epic, even when it was working befor i flashed to froyo it still was really slow. But anyways after i flashed to froyo and deleted all my content from my phone, lost all my pictures/music/emulator roms.... Moral of this story.... dont d/l to froyo yet. any1 can explain to me in greater detail how to fix this damn thing. im a newb to this crap and now i want froyo off my phone and back to eclair as long as i get my gps back. I live in a new area and i need my gps badly.. please help.
[Epic 4G Android Development] omair2005:
maxhax200..try this method.

This method worked for me and it seems to be the easiest..

1) Download DI18 and DK28 for here: http://xdaforums.com/showthread.php?t=794138

2) Once Downloaded, remove .md5 extention (if you have it, I used a download manager and it was there). So now you only have .tar for both files.

3) Put your phone in Download mode (hold 1 on keyboard and press power) ODIN to DI18. Uncheck everything but autoreboot. Place the .tar file in the PDA.

4) Boot up, get a gps lock. Best way is to google navigate to somewhere and leave it in the background.

5) Once you get a gps lock, power off and put back in download mode.

6) ODIN to DK28. Boot up and you should get a GPS lock.

7) Root using the new method found here: http://xdaforums.com/showthread.php?t=770388

8) Flash custom rom!

**Remember you must run ODIN first on the computer then plug phone in USB while in download mode.**

[Epic 4G Android Development] xlr8er:
confirmed
[Epic 4G Android Development] xlr8er:
if you flash ONLY the DK28 modem NOT the whole rom, it will only overwrite the modem which is absolutely RELEVANT because to ODIN the full DK28 rom results in the reason this thread exists in the first place
[Epic 4G Android Development] Firon:
I used Odin to get to DK28. My GPS works a-ok, even indoors I managed a satellite lock (7 sats) in maybe 10 seconds.
[Epic 4G Android Development] styles420:
You are correct, and that's the method that I used (Odin to full DI18, establish lock, adjust GPS if necessary w/ dialer code method, then Odin just the modem and repeat the lock and adjust procedure. Finally, use update.zip to flash the rest of DK28)

But the OP's method is advising to Odin the full tar for Froyo halfway through the process, and that makes any prior steps irrelevant
[Epic 4G Android Development] xlr8er:
good for you , but that is a rather ambiguos post that really does nothing to help anyone with a broken gps. did your gps work before going to DK28? any steps you may have taken to assure it would work? anything helpful at all? enlighten us...
[Epic 4G Android Development] tsperez:
Sprint nor Samsung did this to you. You did. As a matter of fact Sprint has said NOT to install the leaked DK28 ROM.

My phone was perfect before I flashed the leaked ROM but I like to live on the edge. Of course now I wish I had not flashed or at leasted waited to know the procedure that I should have used to upgrade my phone.

Soooo... 1) go back to stock or 2) wait for the official update. I'm doing #2 for a few days but if nothing appears OTA (or here) I'm going to do the flip-flop to get GPS working again.

[Epic 4G Android Development] sleebus.jones:
Read and learn:

Now, as for your problems that you are blaming on everyone but yourself... There's a reason why they call it the "bleeding edge". ;) All of us who take the plunge and flash do so knowing the consequences. Blaming it on samsung/sprint is just silly, bro. YOU are the one who hit the button. They didn't force you. Now if you got an OTA and it goofed up your phone, then heck yea you've got a reason to complain.

Ok, off my soapbox. Sorry guys.
[Epic 4G Android Development] plapczyn:
Chill out bro. As you well know, reflashing a ROM off of XDA breaks your warranty and is aways do at your own risk. You state in your email that you are a noob, but then complain when something that you did goes wrong. I am not a carpenter. If I were to try to make a violin it would probably not turn out well the first time. Tinkering with devices is a learning experience. You gain more knowledge from learning how to fix things and understanding how they work, than you do if it works out of the box.
[Epic 4G Android Development] bondosho:
GPS works perfectly. I really don't know why people are having issues with it.
[Epic 4G Android Development] schnowdapowda:
I just wanna say the gps status app fixed my gps on frodo. And it hasn't worked right for ANY kernels I was starting to feel like that angry guy earlier in the thread. Getting 7 meter lock.
[Epic 4G Android Development] plapczyn:
I could have, but you can start with method 2 by itself. It just takes longer. IMO trying method 1 first is worth it if it works. The sleeping comment was and is a joke, sometimes people use them in conversations or in prose to keep things light.

Regarding ODIN flashing, it doesn't just magically wipe your your phone. The primary bootloader on your phone calls a secondary bootloader (usually loaded and run out of RAM in my experience (I make flash bootloaders BTW.)) The sbl.bin (secondary bootloader) file for DK28 is different than the DI18 one already on your phone. Also, the PIT file contains partitioning information and is only used when flashing the modem. Potentially (however unlikely since some people can use method 1) this could be causing an issue for some since I don't know what *.pit file they are using. So to answer your question the method's are different and not redundant.
[Epic 4G Android Development] dcorn619:
Greatly Grateful!

All your guy's work is just amazing, I am very grateful that I found a solid solution for GPS. I had been on the verge of giving up thinking I had a bad GPS modem but no sireee, it works PERFECTLY! up to 3 meters all the time!

Merci Beaucoup Mods!!!
[Epic 4G Android Development] styles420:
Plapczyn - all I was saying is that the two methods are practically identical... Maybe it's a semantic issue. But you are clearly knowledge, and your insight has been very helpful in other areas. I've been harping on a lot of clarity issues lately in an attempt to prevent more confusion among the noobs - I hope you understand and don't take too much offense :-)
[Epic 4G Android Development] plapczyn:
No problem bro. Yeah. As we don't have specs for the download protocol, a lot of it is speculative. The sad thing is that, despite all of the methods being logistically very similar, they could be doing very different things behind the scene. I spent a little time looking into the heimdal site to see if I could gain some insight into the issue, but I think the root cause might end up being a unknown.

To me, as someone who programs bootloader firmware for a living, the difference in the SBLs between my two methods is worthy of differentiating them. I used method 1 sucessfully.
[Epic 4G Android Development] jbadboy2007:
I had no gps on froyo before doing this method. Im getting gps lock in my apartment now and i couldnt get lock in there on eclair. also my accuracy on eclair was 98.7 ft outside now in my apt the accuracy is 13 ft holy crap and it locks real fast fn SWEEEEET
[Epic 4G Android Development] aleph23:
Still no luck

Firstly, thanks to everyone for all the potential methods to fix the GPS issue.

At this point I'm just curious if I'm the only one who hasn't been able to get this to work. If so I'll keep trying, but if there are others who have tried all of the above methods without success I'd like to know as the GPS feature is too important for me to and I'll have to go back to 2.1.

At this point I've spent 3 hours trying everything here (several more than once) and Have had no luck. I get a good lock with DI18, and again with DI18+DK28modem, but then the final step of full DK28 kills it every time... :mad:
[Epic 4G Android Development] plapczyn:
A) Once you get to the DI18 ROM + DK28 what are you attempting to flash over that?

B) Which methods have you tried? All 4?

C) What version of ODIN are you using? Some have found better luck with 1.3, others with 1.61.
[Epic 4G Android Development] aleph23:
A) In your methods one and two I use ODIN for all steps of the process. I have flashed the "sph-d700-dk28-8g-rel.tar" file after the DI18+DK28modem step. I pulled the DK28 modem out of the same .tar file for the earlier step of DI18+DK28 modem.

B) I've tried both of yours. The second one three times. SINNN's method once. Omair's method was the one I tried first. (Seemed easiest).

C) ODIN3 version 1.0 Not sure how that would make a difference, since I don't get errors and everything seems to install well enough, but I'd be happy to try a different version. Go with 1.3 or 1.61 for my next attempt?

Thanks again for your help. BTW, I will be moving to your ROM if I can ever get this to work, sounds like exactly what I've been wanting.
[Epic 4G Android Development] aleph23:
Interestingly, now that I've restored to my previous DI18 backup (last backup before DK28) I see GPS satellites (with GPS test app) but I don't get a lock...

EDIT: ODIN-flashed stock DI18 modem and now GPS locks.

EDIT-2: Newer version of ODIN seems to have made a difference. After installing stock DI18 modem over my previous rom, got lock. Then Stock DK28 modem, same rom, got lock. Then stock DK28 complete, got lock!

Thanks!
[Epic 4G Android Development] plapczyn:
Yeah the flash tool could have been at fault for all we know. It's not like ODIN is a tool you can from the store. It is an internal samsung tool that could have any number of bugs that we have no idea about. Glad you finally got that. I pushed the ODIN version hint to the front post.
[Epic 4G Android Development] maxhax2000:
Sweeet thnx i got it working back to stock now, plus i checked out and got gps fix and now gps is instant. so now im thinking about enabling gps and turning it off and useing that happymod thing "hold down down/volume, and power, and camera at the same time when u boot up. to load froyo. think that would be good? not that i dont trust odin, i just dont trust my windows.

[Epic 4G Android Development] SamTime:
I am definitely a noob to this process, so bear with me if this is a stupid question. But I haven't been able to find out anywhere how to just ODIN in just the DK28 modem. I have only been able to locate the full file. Is there a seperate file with just the modem, a seperate sub-file in the full download with the modem, or is there an option in ODIN that lets you select only the modem?
[Epic 4G Android Development] SamTime:
Ok, I'm answering my own question here, but I found the files here: http://xdaforums.com/showthread.php?t=861220

For noobs especially who might not have all these files lying around it's important to have links to everything they need to follow these instructions!

[Epic 4G Android Development] kalico17:
heres a guaranteed fix.

Flash back to stock, DI18 through ODIN. boot the phone up fully. test your GPS if your not confident.

turn the phone off, boot into recovery. Apply the 90meg, 2.2 Update zip..

let the phone boot fully, test GPS if your still not confident..

now flash the rom of your choice.

GPS will still work

i have dones this multiple times now and my GPS still functions perfectly..

no modem update or anything else required..
[Epic 4G Android Development] tsperez:
Since you have done this several times correctly could you provide the links for us. I am bone stock but updated the DK28 and have no GPS plus it's running slower than my old DI18. Need links for :

DI18 -

ODIN -

2.2 update fix (don't know what this is)

Final ROM - Is this DK28? Recommended ROM?

Thanks in advance,

Does your GPS drop after 5-10 minutes randomly and then gets a gps lock a minute later?

Anyone having this issue? My GPS works fine but it just doesn't hold for anything longer then 5-10 minutes. My wifes not rooted di18 stock epic 4g does the same but no as often as mine. I'm rooted with ext 4, dk28 midnight rom.

I've done every odin trick of making sure i get locks as i upgrade from di18 up to dk28.

Anyone else have this problem?? I don't see anyone posting this issue or maybe i missed their post.
[Epic 4G Android Development] hayabusa1300cc:
The gps in this thing is weak as hell. If you don't have it sticking out the car, it will drop signal. Even if you hold the phone is enough to weaken the signal...

Hey Guys, any other method to try, I've tried each method several times, my phone is not getting a lock even on 2.1, any input on that?
[Epic 4G Android Development] plapczyn:
All of these methods rely on being able to get a fix in 2.1. If you aren't using a STOCK DI18 rom, then do that first. Were you EVER able to get gps on the phone? It is possible that there is something wrong with your phone. If you were able at some point, the likeliness of a software issue increases.
[Epic 4G Android Development] reyex:
I was able to get a fix before I did the Froyo update, after that I went back to the Stock DI18 and can't get a lock on the GPS, tried different modems, tried Odin 1.3 and 1.61 and no luck.

After that I did a CWM Recovery and still no luck. :(
[Epic 4G Android Development] davidrools:
Thanks!

Thanks very much for your post. I originally broke GPS by CWM'ing straight from stock to EXT4+DK28 modem+dk28+Quantum. Went and Odin'ed full stock DG27, then DI18 and finally DK28 getting a successful GPS fix after each flash.

Still can't get lock on Froyo

I still can't get this to work. I have tried both Odin 1.3 and 1.61. I even have 1.7.

When I flash to stock DI18 and pull up maps. Works. Then using Odin I apply DK28 modem.tar and it works. Then using Odin I apply DK28 and no lock. I was so hopeful as my problem sounds like the others.

I've tried the process through on all Odin 1.3, then I tried it again on all 1.61. I tried going from stock with a lock directly to DK28 as well. I can't seem to find a scenario that works.

I also downloaded GPS Status and wiped cache. No luck.

Any other ideas. I'd really like to go to Froyo, but need GPS for traveling.

Thanks for any help!
[Epic 4G Android Development] mis3:
Same with me. No problem getting a lock, but Navigation drops after a couple of minutes. Using GPS status or Maps, it locks again quickly, but then drops more. I plan to experiment over the next few days with the following:

1) cache cleaner ng

2) Clearing AGPS data in GPS status

3) Using sprint navigation instead of google nav

If none of these work, I'll switch roms and start over.

Hello,

I've installed the adt plugin for eclipse, im on configuring adt plugin.

Configuring the ADT Plugin

Once you've successfully downloaded ADT as described above, the next step is to modify your ADT preferences in Eclipse to point to the Android SDK directory:

1. Select Window > Preferences... to open the Preferences panel (Mac OS X: Eclipse > Preferences).

2. Select Android from the left panel.

Ive got this far android is in the left panel...now im trying to find the SDK location and can't any ideas?everything is default installed.

3. For the SDK Location in the main panel, click Browse... and locate your downloaded SDK directory.

It works fine for a few days (time is random, I have not been able to manually reproduce the issue), then randomly I lose all reception. Switching to flight mode fails, it gives no error, it just does nothing, in the notification bar it just says (searching). I have to reboot the phone to get the phone functioning again.
