[Q] Wifi/GPS doesn't work in any custom rom - Epic 4G Q&A, Help & Troubleshooting

When I rooted my Epic 4g installed a custom rom my wifi and gps would stop working. I installed the modem and I was using dx28.
I also tried rooting my brothers epic 4g to see that its not just not my phone and I came across similar results. I followed the forums step by step.
I got so fed up that I returned the phone to stock forum, however I am getting a little impatient on Samsung to bring 2.2 because 2.3 is already out and 3.0 is coming pretty soon it seems.
The Roms I tried were, Nebula ROM, ViperRom, Bonsai, SyndicateROM, Supernova..
Even using just the stock 2.2 froyo leak I still have the same problem. Am I doing something wrong here?

Even if you flashed everything correctly, this is caused by the modem. Start from scratch. DI18, DK28 Modem, whatever instructions you were given.

I had the same problem with my GPS..
To get mine working.. I flashed to stock DI18 then Flashed the modem separately (DK28 moden only) then Flashed to Full DK28.. then custom ROM
This was helpful as well...

thirdly.. try clearing the GPS cache wtih GPSTest (found in Market)

I had to odin the DI18 then flash the DK28 update.zip to get mine to work correctly.

[Q] 4.02 to 4.03 Lucky or Did I Fix Permissions?

I went from ViperROM [Apocalypse] EXT4-RFS Dual DK28 4.0.2c to
[ROM]VIPERrom [FRoZeN] EXT4-RFS Dual DK28 4.0.3 and have it working without Odin. First time loaded the rom it hung and rebooted. Wanted to go back to 4.02c. Installed 4.02c no wipes (because of script). I thought I would try frozen one more time. Then did all wipes and used the fixed permission option..then installed Frozen and worked after that. Did I get lucky or did the fix permissions do anything? Note I am running DK28 RFS. Just wanted to share in case this is a potential work around that is actually pretty simple did with no computer from my couch while watching TV. ROM is as usual AMAZING!

GPS Still not working after flashing fix

Hey All,
Long time listener, first time caller. I tried searching the forms for my exact issue but came up dry. My GPS still isn't grabbing a lock on Google Maps or Navigating after flashing the GPS fix; if I have to reflash the whole shabang again, so be it, but i'm trying to avoid taking that route.
Does anyone have any convoluted steps on helping my phone grab a GPS signal? after the flash i obviously rebooted and got nothing, so rebooted again and still got nothing. I've tried using GPS Fix in the app store but to no avail.
Phone: Epic 4G
ROM/Kernel: Swiss Cheese Samsprint EE03
Flashed: EC05 Modem and GPS Fix.
Please feel free to hammer down on me if I didn't write this post to spec, i'm just trying to get this figured out while i'm out golfing.
This site has saved me numerous times, so thank you in advance.
This was an issue with the old DK28 release. If the other fixes didn't work and you show no satellites with GPStest from the market, then you probably should try Odin the EC05 tar, get a lock there and leave it locked, then boot into your CWM and flash the EE03 stuff. But remember it is a beta release and all phones are not created equal.
That didn't do the trick, but thanks for giving it a shot anyway.
Good rule of thumb when upgrading a modem is to get a GPS lock on your known good ROM or on the stock ROM first before you flash your new ROM. This is the best advice I can give on the topic.
Running Swiss Cheese using the EE03 modem. First time I upgraded to Swiss Cheese the EE03 modem would not lock. Restarted from stock EC05 ODIN, upgraded modem to EE03, booted up and got a GPS lock. Flashed Swiss Cheese and all is well.

So you Odin'd back to EC05 and still no lock while on EC05?
I haven't had gps since before dk28. Lost it sometime during 2.1. Rooted and tried everything available at the time. Still nothing went to dk28 and stll nothing nd left it there for a while. When I first odined to ec05 I followed all direction except for the gps lock and when I went to ee03 istill had no gps. I reflashed eco5 and the ee03 modem and got the lock, flashed ee03 and gps still works. I'm about to flash to something solid tho my battery life is crap. Dunno if its the theme I fashed or the rom, I really think its the theme but idk definitively. Ayways I digress.. try and redownlod and get a gps lock every step of the way. Btw I couldn't see any sats either.

[Q] Which stock rom is the most stable?

So I just cannot live with my GPS lock failing and just stopping working after 20 - 30 minutes driving. So I figure I will just go back to the most recent stock ROM via odin. Went to the wiki and its just confusing.
I have ODINd so many "leaks" that I do not remember what the official ROM is anymore. I just want to go back to what would be installed on the phone if I bought it in a store today.
Sorry for the silly question...
EC05 is the latest official. But most of the custom ROMS based on EC05 are quite good. Urban Regeneration, SRF, Simply AOSP, are all great ROMS based on the most recent public release.
Edit: To fully answer your question the ReRFS will bring back to full stock except for having clockworkmod installed and that seems to be what you are wanting. http://forum.xda-developers.com/showthread.php?t=1027904
EC05 is the latest stable release.
EG22 is the most stable 2.3 release except GPS. I think
I went back to ec05 cause the eg and eh had issues with tango making my face zoomed in too close but are there other 2.2 roms that came after ec05? I'm kinda late to the epic but its still a hot phone!

[Q] Data issue after flashing ROM

I tried to post this in the development section, under the rom I flashed directly, but since I don't have 10 posts I couldn't. Anyway, I am having issues sinced I flashed this rom last night. I flashed the hellfire rom, and also the liquid smooth rom. In both roms, when I am using my phone it states that is has a 3g connection in the notification bar, but immediately once I start using the data (speed test, chrome, etc.) it jumps to H+. As soon as I close the application I am using, it reverts back to the 3g connection. Is that something that was done on these newer roms, possibly to conserve battery? I have never flashed any other roms with this phone and until recently was sitting on stock rooted UVLH2.
Also, another question I had is when I flashed both of these roms through CWM 6.0, everything installed correctly but the baseband stayed on UVLH2 and didn't update to the LI7 or LI8 that it was supposed to, and I had to directly install LI7. Is that normal? I came from the Vibrant and G2X and whenever I flashed a rom, it normally also changed the baseband itself. I have tried searching before starting this thread but haven't found an answer to either of these questions. Thanks for any help guys.

[Q] Weird GPS problem. What happened?

Yesterday my gps wasnt working at all. It would not lock on no matter what I did. I was on a custom rom and I tried wiping my data/cache, reinstalling maps (just for giggles), and a multitude apps from the market that help deal with gps problems (gps fix, gps status, toolbox, etc).
When all this didn't work I decided to odin back to the last official JB update and still no gps. On a whim I decided to odin back to an ICS firmware and that made my gps work. I have no idea but it did. I then odin to UVDLJC, installed TWRP's most recent and restored my backup of the custom rom I was using in the first place and gps now worked.
While I'm happy as heck that my gps is now working and that it was not a hardware issue I'm extremely curious what happened.
I have flashed many roms lately and I cannot think what a custom rom can do to gps to hose it or if it was just one of those things. I would of thought that when I originally did an odin to UVDLJC that would fix the issue but that didn't. Whatever the flash to ICS did fixed it but what in the heck could that of been?
I figure if I can find out or get an idea what happened then I can steer away from flashing certain roms, or just be prepared that flashing any roms at all can make this happen again.
Same here.
Hello, ddcoh.
I am currently having the same issue you had with GPS not working. I've tried everything from trying tedious Play store apps to trying many different roms and kernels (clean installing every time) to completely reverting back to stock including using TriangleAway in case that did any help. Nothing worked. I have been thinking about going back to ICS to see if that worked but the last time I tried to downgrade from 4.1.1 to 4.0.4 I ended up soft bricking my phone even though I followed the steps word for word.
Can you tell how you went about downgrading to ICS and then back to JB, please? I use my GPS a lot and I would hate to find out it's a hardware issue.
Typically, it's been when people are going from 4.2 to 4.1.

Well I used odin to flash an T999_UVALEM which was a prerooted ICS rom. After booting it up I checked to see if GPS was working and it was.
I then used odin again to flash T999_UVDLJA which is a JB rom and booted it up also and saw that gps was working. Then I just restored a backup of a room I had been using and GPS still worked.
I've been out of town and noticed that after flashing a few roms that gps wasn't working so instead of doing all the above stuff I just flashed a cm10 rom. I believe I either used a cm10 nightly (or maybe 10.1, memory is hazy) or LiquidRom and that got the GPS working by just doing that. Not sure if that will work for you but you could always backup your setup using TWRP's latest and then flashing a cm10 rom and seeing if gps is working and if that fixes it then you could then just reboot and restore the rom you are currently on and that might fix your gps for you.
