[Q] *HELP!*T-Mobile Galaxy S II Network Problem

OK guys i'm a complete noob here at XDA (registered yesterday) but i'm getting really desperate and confused and since i've seen XDA is such a great community i thought i'd give it a shot...
My GSII had been running BeastMOD ROM II v3.0 for about a month now and it worked like a dream but about 3 days ago i turned off my phone and then turned it back on a minute later and I HAD NO NETWORK!! Now, that i recall i didn't do anything to cause this. I called t-mobile and went through all their troubleshooting, no luck. I flashed BeastMOD ROM II v4.2, no luck. Re-flashed BMOD 3.0, no luck. I noticed i don't get ping to my network, I have no IMEI number(i get null/null), and no baseband version(unknown). I'm really worried and hopefully you guys can help me some suggestions ASAP as i haven't had network in three days.

restore a back up of your stock if you still have it.

and this will only get me back to stock and not undo root or will it? will try

Here's what happens. I try to do my first stock ROM restore and it says
"Checking MD5 sums...
MD5 mismatch!" <--Whats wrong? I'm currently doing a restore on a backup three hours after that one which i'm not sure which one it is (maybe the first backup after i installed BMOD 3.0) but hopefully it will do something.

Hey thanx for that last link but the freakin person that made that method just bailed on me after his method screwed with my phone. I have stock now but i have a problem where my phone keeps rebooting until it gets network and even after it finds network and gets its IMEI and Baseband version back, that "fix" doesn't let me use data and for some actions the phone says the SIM card is not ready or available. and when i turn off the phone and back on it keeps rebooting until it finds network like i said. I don't know what the EFS is but that could be something that is making the phone malfunction. Please! Someone help!

i had almost the same problem.
My IMEI is still there, but it just won't connect to any network! All of a sudden, I woke up and it wont connect!
I'm getting a replacement sent to me from tmobile. weird.

Radio issues with 4.2 Roms

Hi all, I am again posting about having radio issues. (NO T-Mobile signal) Any 4.2 Rom I try to install, I am unable to obtain phone service. (signal)
Here is what I did:
1. Start from scratch, total erased phone and sd card and micro card.
2. Odin flash stock Rom and Odin flash latest TWRP
3. Copy Rom to SD card and flash. (flash is fine)
4. No signal, flashed newest UVM6 radio, all kind of wipes.
My phone is SGH-T989 T-Mobile. I even changed the APN, but still only pick up AT&T which still having no signal bars. I tried flashing all radios available with no help at all. I am able to use certain 4.1.2 Roms such as Infamous 3. I even tried different kernels, different wipes and just can not get any T-Mobile signal service. I have tried searching for any and all radio issues for this phone. NOTHING works for me. Can anyone or does anyone have same problem that came up with a solution to get a signal for T-Mobile for these Roms? I am currently using the Infamous 3 Rom using Arc kernel. Actually the only other Rom I can use it the stock deodexed rooted base. Very frustrated not being able to use these great looking Roms, HELP please! Thanks for any information or solution. BTW, I have tried everthing and every type of wipe to no avail.

do you still have your IMEI or does it shows blank and unknown ??

I am having the same issue. It does show my imei # though. How do I fix this?

Oh boy.....again.
K....here is about everything. If none of this is your problem, since you say you've checked everything....and yes, I have read your other thread....in which you repeatedly say you tried everything, then you have a hardware issue, or are simply doing something wrong and telling us you did it right.
Not getting a signal.....
- not using latest T-Mobile or Telus radio. Maybe you flashed it, but is it actually showing as that radio in settings??
- APN settings are wrong or don't exist. Lets pause here. You said you checked apn and only pick up at&t. Or am I misreading that. If you don't have the correct T-Mobile apn settings, then you wont get a signal or data. Period. This has to be correct before bothering with anything else. You said you checked. Against what?? I've seen plenty of apn settings when Googling it, some simply don't work. Maybe they are old settings, wrong phone, whatever. I'm Telus, so can't help you with the settings for T-Mobile.
- what has already been posted above needs to be correct.
- maybe radio file you flashed was wrong one or corrupt. Perhaps try the Telus one. Should work too. Since T-Mobile radio works on Telus.
- restoring any system data after a flash? Huge no no.
- wrong mobile band selected?
- and a possibility .....simply no signal where you are. Or it's a weak signal, and your assuming it doesn't work?? Ignore this if you have a very strong signal usually where you live. 4.1.2 to 4.2.2 shouldn't affect signal much if any.
Anyway.....that's about all there is to it if you are CLEAN flashing roms and following instructions to the letter. I am confident you will say all the above is good....and if so....I am afraid you will probably find no answers like your other thread. Meaning you have an extremely rare issue. Or a wierd hardware issue, sim card maybe....tho before you dismissed that as a cause. Another possibility is that you aren't correct when you say apn is fine, or the radio you flashed is fine. Not accusing you of misleading anyone, just saying perhaps you are innocently wrong when you tell us this or that is fine when it is not.. I've done tech support.....happens all the time! !!
So, good luck. Hope you find a solution ......tho this is your second thread on same issue....so you may have some rare issue....and may be boned.

I have been dealing with this problem for weeks, and I can almost guarantee you don't have the radio right and that's the problem. http://forum.xda-developers.com/showthread.php?t=2385987.
Here is the link to a radio I just flashed literally 5 minutes ago and started running 4.2 roms after weeks of struggle and frustration.

That would certainly make sense!
He's got something wrong for sure. Or he's got a strange phone that won't work with 4.2. And I doubt that very much.
He's got wrong radio, or wrong or missing APN settings.
Or wrong phone, sim or carrier.

Thanks for helping and I think your right about being boned or hardware issue. I have tried different downloads of radios, both Telius and Tmobile and copied APN settings from working stock Rom. Maybe bad Sim, anyway I will have to stay with what I have until I get new phone, which is soon. Thanks again!

Stumbled across this. I've never heard of this particular issue before, but sure sounds the same as your issue. Try this fix if you haven't already.
Everything below is copied from another thread......
i had this problem with slim too. i thought something went wrong with my phone or my area. but nope. what you need to do is go to mikeyman777 cm10.1 thread and find the uvmc6 tar file, then use odin to flash it. apparently just flashing the newest radio with twrp isn't enough because it's missing some files or something like that lol.
anyways i haven't had signal problems since flashing radio tar file. i've lost signal like once. before i was losing it everyday. hope this helps.

CM11 No Mobile Network, Mobile Network State Disconnected

Whenever I flash cm 10.2 cm 11 any rom at all I face the problem of no internet. So I go back to stock. I have my baseband, build # important stuff like that. I always have to take out my assert lines. So when I flash any rom the fine line will say;
;Mount
or something like that I delete all the assert lines and I was told to keep assert lines but just change them to my baseband and stuff. Any help would be appreciated. & btw the problem is it says Mobile State: Disconnected. But I'm in service too.

I have the same problem. Been searching for a while and trying different fixes, but doesn't seem to be working. I'm on ATT galaxy S3, tho. If someone's got a working ATT S3 and let me know exactly what ROM, gapp, modem, etc they used, would much appreciate it.

More info is needed, such as carrier. I'm guessing either Virgin Mobile or Boost if you need to remove asserts on any of the pre-unified builds (this would hold true for any ROM that has switched to d2lte from d2spr). If that is the case, then you don't have the correct APN's configured. Also, it usually doesn't hurt to be running the most current modem (MK3 for Sprint, MK5 for VM/Boost). Again, the more info the better, then people don't have to play Twenty Questions in order to get to the heart of the matter.

This may work...
So, after trying countless options that i found on this site, and after dozens of flashing roms, modems, kernels, booloaders, restores, etc... turns out that i was doing everything right and there was nothing wrong with the install or the phone itself. After contacting my carrier (PTEL Mobile) for the third time, (first time they told me they had an outage, second time they told me to set the APN setting correctly - neither of which was incorrect on my end or the cause), they said they will try RESETting the DATA on their end. And guess what - that worked.
If you think you did everything correctly but still not getting data, i suggest you make your provider to do the same, or at least pry them as much as you can about your problem and what they can do about it. I wasted to much time and effort (my poor phone) on this and the solution was simple, and not my fault. Hope this helps others.

Hiya, I'm currently having the same problem as the OP. Mobile state disconnected but it says I am in service. Using latest version of Philz recovery and I flashed the most recent nightly of the Cyanogenmod 11 -4.4.2 KitKat (April 5th, 2014).Carrier is Virgin Mobile, using Samsung Galaxy SIII SPH-L710. PRL is most recent one 33030 and modem is MK5. I did however, flash the rom without deleting the assert lines, since I did not know I had to delete some assert lines. Any help with this? Thanks.

Deleting asserts is only for d2spr specific builds, that doesn't apply to d2lte builds (hence the reference to "pre-unified builds" in my first post). Your issue is most likely also related to APN's. However, there are also known data issues on a lot of the latest CM nightlies, and also on the ROM's that rely heavily on CM as a code source. I would strongly recommend reading the last several pages of the thread for any ROM that falls into this category in order to see what other users are reporting along these lines.

CM11 No Mobile Network
Hey guys,
Noob here. I'm running CM11-20140428-NIGHTLY-jflte on a Galaxy S4 GT-i9507(international, optus) but bootscreen now says 9505(not sure if that's important).
I've had Mobile Network State: Disconnected for the last three nightlies. On CM11 M3 it was working all good, but now no luck.
So I've tried a few things and I've come to the point where I'm going to try the factory reset then reflash CM11 and fingers crossed it will work.
Can anyone talk me through the proper procedure for this? I've made a full backup on my external SD using CWM 6.0.4.7 and transferred it to
computer just in case. So would anyone be awesome enough to take me through it step by step.
Cheers,

hhmmm

Stock no APN settings at all
I have looked everywhere and found nothing for the last 3 weeks. I have a stock, sprint S3 on straight talk (my son's phone) it will not get 4g lte data what so ever. My phone is the exact same phone, and it does get 4g lte data. I tried all the basics ##72786# data on off check airplane mode...nothing. Mobile network state is "disconnected". So I opened data ##3282# to compare apn settings with my phone. I made sure everything matched, and when I get to "LTE APN Settings" I open it up, and nothing is there except APNs nothing, blank. Also missing is "Dial Up Networking" that option does not exist on my son's phone. He updated to kitkat (uggh) but the problem was present before that. Checked the phone, and it is not rooted. Funny thing is the phone updates with 4g lte running after dialing ##72786#, but that goes away after it completes. Texting works, but no mms (pictures etc.) and if I set it to cdma only it gets 3g, otherwise no data at all. Anybody?

4G won't stay connected

I've tried all sorts of roms, AOSP and Sense, they all stay connected to 4g for a few minutes at most after a reboot and then go back to 3g.
Everything else works fine, and my sim works good in other phones and stays on 4G.
Any idea what this could be or what is causing this?

Have you updated to the latest firmware? If your using kitkat roms, you need kitkat firmware. You can find the firmware in the second post of santods stock rom thread in development. Use the no boot.img one.

Yea I've flashed those also. Everything used to work fine until that roaming display issue. Never returned to normal for me, even tho roaming is gone.

Have you ever ruu'd back to stock and then done a factory reset from hboot? That is the only way to wipe out the network settings and force them to be updated. Worth a try i guess.

I guess that's my only option, thought maybe I'd be able to avoid it.
I'll try tomorrow and update.

Tried to ruu back to stock yesterday and still getting the same results. No 4g after a few minutes.

I'm not getting 4g at all on my phone. I came here to post a question and saw yours, so thought posting another thread would be pointless.
I've got NusenseSIX RC4.5 running and while the 4g icon comes on, there's no data transfer at all. I flashed the new firmware first, as instructed, and that seemed to go just fine according to the directions. But, when I swapped my sim card from my other One and waited a few minutes, even *228'ed, no data.
I got the phone already rooted and s-offed with TWRP 2.7.0.1. How do I get it back to stock to clear out the network settings? Or could it be a bad firmwware flash, so I'm screwed anyway?
EDIT: I redid everything, and just stuck with the Sense 5.5 mostly stock ROM. Data works now. Might've been firmware, might've been the ROM on my phone. Zero idea.

Is it possible to have a bad sim?
I just got a replacement device and I still cannot get 4G service for more than about 2 minutes before it switches to 3G

Sure, you can have a bad SIM, but I don't think that'd cause the drop in data transfer rate... lack of data all together, or other things not working, sure, but if you can actually catch a 4G link and then it drops to 3G, sounds more like the radios, the hardware, or just a bad coverage area. I'm no expert, though.

In case anyone was wondering, I ended up getting a new SIM and that has fixed my 4G issue. No idea what was wrong with the SIM, but anyway it sucked.

Constant "Preparing Network" notification on TW ROM -- my fix

I finally got around to rooting and installing the updated, Knox-free TouchWiz MK5 ROM on my Galaxy S3 (Virgin Mobile), but I hit a problem that some others have seen, including on this post and several others where the phone will not connect to 3G nor 4G wireless and it has a constant "Preparing Network" notification on the taskbar. Trying to run the activation on the phone fails, and when I tried to manually update the PRL or Profile, it just says "Session already in progress, please try again later".
Since I'm fairly new to the board, I couldn't post a reply or question in the DEV threads, but hopefully the solution I had to take will be helpful to others.
I started from a Knox-free MD7 build on my S3 and just followed the root and then MK5 ROM update directions... all of that went cleanly.
The fix was to * Update the Modem to MK5 * as well!
After updating the modem software to match the ROM, a quick reboot later and the activation worked now and, after a couple of minutes (and maybe another reboot or two) it updated the PRL and Profile and both 3G and 4G LTE were working again! :victory:
Looking back now, though, I realize that I got carried away with playing with the new ROM after Step 7 of @jdsingle76 's directions and I failed to follow Step 8...

So...were you able to get it fixed, or are you asking a question? Just want to make sure you got what you needed.

My post started out as a question, but then as I was writing it and going back to link to some of the other questions and problems that people had reported, I ended up noticing the "Step 8 ... flash the MK5 modem" that I had overlooked in my zeal for playing with my new OS and getting all my apps restored.
So I ended up re-writing it a bit as -- here's how I fixed the constant "preparing network" -- since it wasn't originally apparent to me that this message & the fact that I couldn't activate meant that I did actually have problems with my 3G/4G data connection.
Thanks for your guide! (I may have another question about WiFi, but I'll post that as an actual question shortly...)
