Modem help... - Epic 4G Q&A, Help & Troubleshooting

For a few days my epic hasn't been getting service. Wifi has been working, but my phone is stuck in airplane mode and cannot come out. I unrooted with the FC09 modem, but that did not help. I've been searching the forums but have not found anything that worked. I am on 2.3.6, using an FC09 modem. Someone please help. Thanks.

have you gone completely back to stock FC09? If you can't turn airplane mode off that's what i'd do. Going back to full stock should get your back up and running, then you can work your way back to being rooted and customs roms once it's working again.

Yes, in odin I did this method http://www.youtube.com/watch?v=QTQ6Rn0FBSk&feature=relmfu. That did not work.

so you can't toggle airplane mode off at all? You might have a hardware issue. It could also be on Sprint's side if you're account some how got updated incorrectly etc.

No, airplane mode does not come off. Wifi works, as I mentioned before, and I actually wen t to a sprint store today, and a factory reset didn't work, they told me to call samsung.

so i guess that means that you're outside of warranty, and don't pay for TEP?
I can't think of anything else to try if you can't get it out of airplane mode and you've gone back to complete stock. I'm sure there's some other explanation why it's doing it, but it's beyond my knowledge..

It has to have something to do with my modem. When the lady at the store tried putting in some code in the dialer it gave her an error that had something to do with a modem. I really want to fix it, calling Samsung would be a last resort. They would probably not help me because they would know that I put in a custom modem, based on the error they got. Maybe a new rom would help?

roms don't change/update modems. Have you tried just the individual modem files? There is a FC19 modem file that was leaked, or you could go back to some of the older ones, maybe EC05 or EL30? There's a thread with all the individual files, maybe try flashing 1 or 2 and see if they make any difference. If you went to full FC09 stock, it should have updated the modem that way, so not sure what the deal is..

Odin in the FC09 modem again and select EFS clear in Odin. When it is finished it should go through hands-free activation again.

Try re-downloading the tar.md5 file and then re-flash it through odin, you may have a bad flash or a corrupt file, either way you'll cover both possibilities by doing the above

I already flashed that with odin, thats what gave me the no wifi/4G issues.

actually this is better, I just realized that was a kernel only and reverting back to a stock ROM, like the one in the link would be a much better resolution for someone in your situation, hope it works out!..EDITED...really??? If this is what gave you the issues to begin with, then maybe try redownloading and reflash this file ...BTW being that this is a new account Im restrict to post 1/5mins, so thats why Im a bit late in case you're wondering
Do it again with a different cable it should work Samsungs cables are notorious for causing issues
update profile when done
Like he said re download the file and odin again. You may have had a bad download. So download it again and odin.
Just stay calm if you can get into DL mode it will be fine. HTC and BB cables work great for Odin
Thanks a bunch guys, ill try that again and report whats up. By the way, what's the "Z image" ? I see a link to download it above the .tar file?
Ok so I redownloaded and flashed the stock Kernel, still no wifi/4G. As an experiment I went back to the custon Kernel I had before and everything is working with that one. I just dont want to keep it because of the loss of service issues. This sucks .

I'm having the same problem now. Need help I have no data!
Sent from my SPH-L900 using XDA Premium HD app
not that I will have an answer or solution, but others who might would likely want a bit more information, like:
are you on a custom ROM, or stock? which version of stock? or did you use that leak?
if custom, how did you get there? (ie: method used to flash/odin, stock recovery/twrp)
if you're just rooted stock, how do you achieve that? which method for rooting, or was it a rooted rom/oneclick/etc?)
did you do anything just previous to the problem? or "out of the blue"? (it is also vaguely possible it Is a network problem on Sprints end...)
if you're going back to BustBuy, are you unrooted now? do you know how to get back to unrooted? (they may not honor your warr if you are)
the more info you give us, the more likely we will have advice. just saying.
You might want to try resetting sprint login data by ##72786# to see if it helps.
Thank you for the quick response but I finally figured it out. I just reinstalled stock Rom and started fresh.

how exactly did you reinstall stock? i just got this problem after a reboot. i was on viperboy's stock K8 and just did a reboot and found my phone no longer has any network. i had twrp installed, the multi window mod, and the reboot option mod prior to this. i odined back to viperboy's stock J1 and had no resolution. i then went on to odin back to viperboy's stock JC, still nothing. i tried doing a restore from twrp off of J1, JC, and K8. after i reset everything and went back to stock i took the phone into sprint who had no way to fix it and could only offer to order me a refurbished replacement unit for whatever the price was. i have insurance from a third party but more then anything i need to know what exactly caused this and how to repair it. i noticed enough posts about this particular issue that i am hesitant to even think about rooting my next phone. when i do finally get a new one off insurance i of course would like to prevent this issue. however, using insurance after a month of owing my phone for this sort of issue really was not why i got the insurance.

thanks again, that solved my problem. i still wonder what in the world had my phone acting up in the first place. i believe i was one of the only people who had this just happen on a reboot without moving roms.
Thank you all for this thread. I just recovered from no mobile network as I accidentally flashed the wrong ROM. :good:
The process I had a failed flash that scared the @)*$& out of me. But i believe it flashed the modem.bin before it failed.
Then i flashed CWM again and all was good.

[Q] Help... MEID, BASEBAND version, etc unknown.

I have a Galaxy Note 2 on the sprint network. Yesterday someone sent me a text and i tried to sent them a text back but my phone didn't have a signal. It reset itself a bunch of times. It stopped resetting and now there is no signal to the tower. I looked on my phone and Baseband version, network, mobile network type say unknown. service state is out of service, username is unavailable. mobile network state is disconnected, my phone number is unknown, min unknown, prl version unknown, meid unknown, imei unknown, iccid unknown. device status modified.
I rooted my phone when i first got it with the method that doesn't make your flash counter go up. I had super user installed and had the OTA survival mode checked and did the OTA update for multiwindow and then lost root. This wasn't a big deal to me so I just left it alone, everything worked. Its been a couple of months and then this happened. I reflashed a stock rom on the phone and that didn't fix anything. I rooted it with the Samsung Note 2 toolkit and that went well. But it somehow got stuck on the boot screen again after a while so i just reflashed to stock.
I downloaded QPST and entered my IMEI into the nv line 550 and clicked the write NV block and returned an error. Im stuck. I have insurance and I've only had the phone a couple of months. What the heck happened? Was it somekind of wipe? I have been working on this all day and I'm going to bed now, but can someone help me out?
I would not have been so quick to start messing with qpst.In most cases where ive seen this the imei and related numbers were fine and it was a system screw up. That said,This happened to me recently and even odin wouldnt fix it. I ran THIS and it brought me back so I would try that first.

thanks. I am downloading that now and will try it and let you know. I didn't want to start messing with qpst but i saw a tutorial that you can enter your imei back into your phone with it. i got my numbers off the box and went to work. but qpst would not write the values into my phone.
when i plug the usb into the phone a flag pops up in windows and says hardware id is missing as well.

i went to the link. i downloaded the file. it was a zip file so i put it on an sdcard and slapped it in my phone. i used the vol up, home key, and pwr key and then i used the update from zip file on external storage. it did some stuff and rebooted. i checked my flash counter and it went up and said i was running custom, custom.
i didn't see any instructions with your post that you linked and I probably didn't use that file the way it was supposed to be used. how exactly do you use it? and when i turned my phone on it still said baseband unknown.
thanks again for helping me with this.

Do you have Root Explorer? If baseband is showing unknown makes me wonder if build.prop is there and complete...?
It needed flashed in a custom recovery. Did u use twrp or cwm to flash it? If so, you did it right. Is it only the baseband thats unknown or everything still? Did you try a ##72786# dialer code reset?

I don't have root explorer on here right now because I was trying to return the phone back to stock for a return to the sprint store.

everything is still unknown.
when i dial ##72786# it goes to a meny labeled SCRTN but is blank with no options.
at this point I used triangle away and flashed the stock rom on my phone, it keeps randomly resetting. in the setttings it still has baseband unknown. i did the ota update and the build number is JROO3C.L900VPALJC
under status, everything is unknown and at the botton it says device modified.
when i put it into download mode right now it says custum binary: no ; current binary: samsung official; system status: custom
this started when the phone just started resetting a bunch after my buddy texted me and then it didn't have service and all the values were wiped, i just want to take it back to sprint because ive only had it for a couple of months. will the above values be ok for a trip to the sprint store?

I had this happen to me when I first got the phone and rooted. Scariest first day of ownership thought I was going to have to go in to sprint. Thankfully I flashed the full stock tar and my phone came back to life. Maybe you should try flashing it and see how it turns out for you.

as it is, does the spring store take your phone back if system status is custom and device says modified?
b.) if i can fix it, it would be better than taking it back. everything on the phone still works, but it obviously cant see a cell phone tower or make calls. data on wifi only type deal.

I'm not familiar with that EFS issue since I've never read about it. However I would try that tar I posted as a last resort since the stock zip didn't do anything for you. The issue you're describing is the exact same thing that happened to me and that tar brought me back. And about being custom/modified it all depends on the Sprint Rep you get. Some are cool about it some are not.

my phone is screwed. i got the MSL and put it in my phone and nothing happens. i have to take it back and get a new one.even though all the hardware works, just cant program the info back in the phone for meid, baseband, username, icc id, etc. etc. so no voice calls.
the bummer is that this all happened randomly. i wasn't messing with my phone at all and it was running great then it reset a bunch of times and then wiped everything. i don't know if it would have helped, but i highly reccomend everyone backing up their EFS. because you never know when this will happen to you.
take care, thanks for the help everyone.

No data at all, even after odin

So running the latest version of Darthstalker for close to a week, all of a sudden I had no radio. No wifi, no signal, nothing. I came home and downloaded the stock odin, and nothing happened. I wiped phone and factory reset, did it again, nothing. Then I did the samsung official odin, and now I only have wifi. I re-rooted and put Frosty on my phone and installed ktoonz kernel to see if this made any difference, and it didn't. I still only have wifi. I still have my imei # in settings, so i didnt lose it like i did on my note 2. I really don't know what to do at this point. Im sure it's fixable, and I've seen other people with the problem, but all people say to do is odin. I used both odin files in the odin thread and I still only have wifi. I need signal for this phone, so many people for work etc. Can anybody help me? thanks in advance.

Real bizarre issue, Could use some help Please!

I have been tinkering with my Epic 4g sph d700 and for whatever reason, despite flashing it using a tar file as well as the pit, using Odin, I cannot get a darn mobile signal, it fades constantly in and out of an O with a line through it (like the NO symbol) and If the bars pop up I don't even have 1 signal bar.
I literally have NO data whatsoever. Any idea what could be causing this?
Should I use Heimdall instead and does anyone know of an FC09 or FC19 Heimdall latest full stock file can be found? 99.99% of the links I've found are no longer valid and believe me I've googled for a couple of hours as well as searched XDA.
Thanks!
ANY help or suggestions would be appreciated. It's stock, FC09 right now, Android debugging checked. Ready to flash away, but I have no data at all unless I am on WiFi.
I did not have this issue when I was on CM10 yet I went back to stock and now, nothing but zero mobile data issues.
Here is a link to the FC19 tar.
Try giving fresh slate another go.
Have you tried updating your PRL/Profile?

When you go into Settings->About what do you see as your baseband version?
Is it blank?
There is a way to update PRL manually, but it's outdated and I can't really recommended.
Try flashing this modem and wiping data/cache 3x.
Try this as well. Just let me know what happens.

I don't know how but you may want to confirm they still make them. Possibly this is a counterfeit phone and that is the reason for the poor signal strength/quality? There have been counterfeit Samsung S3s/Note 3s/S4s showing up (see Youtube).
Download a stock tar with pit, odin it with efs clear. This will clear everything and I do mean everything. Your phone will be completely wiped. Keep in mind when you do this it will pop up with sprint activation wanting you to activate. If that don't work then maybe a antenna is loose internaly or maybe its just plain broke.
