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.
I want to preface this by apologizing if this has been covered, but I was unable to find anything with a search.
Every single 3.70 based ROM results in wakelock issues within 24-48 hours. I have tried everything, including flashing the stock rooted rom and no matter what, my phone stops sleeping after a day or so. I fully wipe, flash the rom, and I don't download a single app until the wakelock kicks in, at which point I grab spare parts and get no useful information.
I am currently alternating between CM7 and CM6 because AOSP roms work fine...they just aren't quite as solid as I would like them to be at this point. GPS bugs (I've tried the fixes), no HDMI (I've heard about the beta apps and I'll try those soon), no 4G (I realize this has been added to the nightlies for CM7, but the GPS issues are a deal breaker for now) and slow file transfers between my PC and my phone when using CM7 also kill the rom for me.
I figured I would simply flash the stock rooted 3.30.651.3 so that I could have a fully functional phone without wakelock issues if the need arose. But whenever I try to flash after a full wipe (including dalvik cache), I get stuck on the white HTC EVO screen. All 3.70 roms and AOSP roms flash fine so there must be something I'm missing...do I have to downgrade my radio or something? Any help would be greatly appreciated. And once again, I'm sorry for the post if this has been covered.
Yes the radio has to be downgraded first. I'm not sure which radio you need but you should check out one of Viruses rom threads since his roms are mostly 3.30 based.
My wife and i got our GNex phones at the same time in April through the Amazon wireless store. Both of our phones had to be repalced by amazon within the 30 day window for 4g/3g/1x signal drop issue. 4g radio would just totally crap out, then would wipe out the 3g and then i would have a complete signal loss. Everything was fine after we got the replacement phones. My wifes phone is totally stock and has had zero issues. Mine is rooted running AOKP toro IMM761, Android 4.04. 4 days ago it started having the rampant 4g signal crash issue again. I've turned off the 4g radio for now, but according to NoSignalAlert, with just the 3g radio on i've had complete signal loss 7 times today. I'm in the same area as usual, my house and my office where i normally have 2+ bars of 4g. I'm thinking the radio has gone bad in this phone, like it did in both of our previous GNex phones, it just took this one 6 months to die. Now i have to deal with Verizon Wireless to get a replacement. They are wanting to make sure i'm on the most current build, baseband etc. Here are my questions.
1 - What is the most current stock ROM, radio, build etc. that i an put back on my phone to both a)make sure that a rooted app/baseband etc. is not all of a sudden causing this issue and b) i can talk to VZW and they won't know i've rooted the phone.
2 - Once i return the phone to a stock ROM, i assume that I will have to do an OTA to satisfy the VZW tech. If the phone does not need to be replaced, i.e. the OTA fixes it, will i still be able to root back to an AOKP ROM?
3 - Is there some other update i should try before going the "unrooted" route and trying to talk with Verizon?
Thanks for your help.

Here are the VZW radios for the Gnex. Personally I would try flashing the new one [4.1.1 (JRO03O)] with a JB ROM. I was on AOKP for pretty much the entire life of my Gnex, 8 months, and never tried CM10. Flashed CM and besides the Nav bar, which I like better in AOKP, I have seen substantial improvements in performance, stability, and even better battery life. If you are determined to stay with AOKP I would still update to the JB version and try those "new" radios.
I started having the same problem a couple days ago when flashing a ROM went bad so I had to restore to an old (4+ mo. old) backup. From there I flashed factoryrom jb and then flashed the new radios today Cuz I just noticed the lack of signal. Still no bars anywhere. Any other thoughts? Do you think flashing a CM would fix it? If so, why?

What is selected in settings-more-mobile network-network mode?
data enabled is checked, and network mode is LTE/CDMA
I was gonna try to find a fix today and if i can't find one, flash to complete stock, reroot/mod etc.

Well, your settings are good to go. Did you check the md5 sum of the radio file after you downloaded it? If you have root explorer hold down on the .zip file and choose properties to check the sum and make sure it matches.
hahaha i guess that's what I get for trying to download a radio on crappy mall WiFi... the MD5 was bad :-/ works good now! thanks!

Hmm, it did this "need to restart SIM to work properly" crap, restarted and stopped working. Any thoughts? I'm installing franco kernel to see if that helps
Welp I ended up just flashing the factory image hahaha, will reinstall ROM and see how it goes. Everything seems to be working fine right now though
Glad it was something simple like that to get you back up and running.:good::highfive:

I d/l the 4.1.1 radio and flashed it in clockwork, and though the flash said it completed successfully, i don't see a way to check the radio version. I don't see 4.1.1 JR03O listed anywhere in the About Phone information...Where should i be looking?
Further, my prboblem seems to have further degaded ...With the 4g radio on, i get random total shut down of the phone, as opposed to simple radio crashes. Just goes to off with black screen. I'm up to try anything. I assume i can easily locate one of these JB ROM's in the dev section?

The baseband i think. Mine is I515.09 V.FF02 / I515.FG02.
I'm not all that knowledgable about the radios I just know my reception/data was poor on JB ROM with ICS radios. When I flashed the JB radio, my issues were fixed. I believe the ROM and radio versions should match, so if you flash JB radio I would flash JB ROM. All the info should be in the thread that is linked.

I am such an idiot, this whole time you've been talking about JB ROMs i assumed you meant some particular brand of ROM, like AOKP or Myn etc... It didn't dawn on me until i saw JB next to ICS that you meant Jelly Bean ROM.
Ok i'm running an AOKP Jelly Bean ROM with Android 4.1.2
baseband is the same as yours
Build is aokp_toro-userdebug 4.1.2 JZo54K
The radio problem seems to be resolved. Thanks for the point in the right direction!
oops, accidentally wiped my sd card when i was restoring back to factory... TOTAL back to factory hahaha.... which isn't so bad i guess... after a year it's about time I guess
I seem to lose signal when leaving wifi though, have to either airplane mode or reboot. Because I had my phone so long, I don't know if there was connection or dust issues, so I did the classic NES/SNES/Sega Gen trick, took the sim card out, blew in there and all that. Seems to still be going ok.
Fyi.. i a simple restart doesnt disconnect u from the towers.. u need to turn off, pull battery, pull sim, and wait for 10 20 sec. That will disconnect u fully..

This is by no means my first rom flashing. I've gone through this on multiple phones and multiple roms on each phone. That being said here is my problem in gritty detail.
Phone: T989D
Carrier: Koodo (telus network (canada))
I was running on the modified koodo rom which I got from the development forum, it was becoming unstable so I restored to a backup of the stock rom. Everything was working well. I decided after a day to flash a new rom, so I first flashed this rom http://forum.xda-developers.com/showthread.php?t=2313530. It flashed well and booted up nicely, everything seemed fine at first glance. Then I tried to do a test call, failed, which made me notice that my signal bar was flopping back and forth between no bars and the circle with a line through it (no service). I went in and checked the apn, all was fine. I tried to flash the radio from the stock koodo rom, didn't help. So I figured maybe it was the rom, went and found a rom http://forum.xda-developers.com/showthread.php?t=2279348 designed specifically for the T989D, and the carrier Telus (who owns koodo, they share a network). It loaded fine and booted up nicely. But it had the same issue with the no signal and no bars thing. I check the apn and it's missing the koodo apn, so I add it manually. Still no dice. Then I go in and try flashing the radio to this rom still no dice. I then tried doing a fresh install of the same rom, didn't help any. Then I tried shutting down, removing battery, sim card, and sd card. Putting in the battery, booting up, then shutting down pulling the battery and putting the cards back in. Also didn't help. I have since restored to my old stock koodo rom (which is god awful btw. It get 7 hours battery life with light usage), and it connects to the network perfectly. I really want to get off of this stock rom, so any advice anyone might have is totally welcome. I will try anything.
PS. while installing the new roms I followed all of the instructions to a T. Using infamouse cache wipe and superwipe when required, whiping everything etc.
Edit Solved by flashing different radios until one worked.
hello my wife has a tmobile galaxy s4, as do i, but her wifi stopped working one day, i tried everything to fix it and nothing worked, so i rooted the phone and and flashed twpr, and tried some custom roms, but they all end up freezing on the lock screen or out of nowhere and ive tried various roms, all stable as they say on the post, but they freeze on me, im on the nh7 baseband and bootloader i used a phone info app to check. what could be causing this with every rom i tried? ive tried the pac-man rom, slimkat, google play edition, dan&ktoonz rom. ive rooted and used roms on my old galaxy s3 no problem.
Try flashing a stock rom, just for giggles & grins. See if that works before you go off the deep end.
Pp.
Where can i get the stock roms
http://galaxys4root.com/galaxy-s4-stock-firmware/ Choose your stock Rom here
now are these flashable via twpr.
Tell me if they helped in anyway
Try working with this as the Web site mentioned before by Pablo has the not so latest firmware, and this is trustworthy from our own forum, just follow the instructions, read through the thread for answers in case you have any questions.
