Keep in mind this is my friend's phone and not mine, I just did all the modding for him.
Was on CyanogenMod Jelly Bean ROM for about a year, and then a month ago it started only being able to get a data connection at 1x speeds.
Went to fix it today by going completely back to stock, used this guide to go to 4.1.1, which is what I just finished up doing.
Rebooted and everything is working with the only difference between this phone and an untouched one is that it is rooted, and it is still having the same data connection problems. Was hoping there would be someone left in this forum with a similar experience that can provide some insight or advice....
My friend went to the Verizon store and thought it would be smart to tell them it had been rooted, and then they told him that was the reason it was messed up and there isn't anything they can do for him, which I don't believe considering the phone was completely factory stock when he went down there.
I'm about to flash CWM back on the device for the time being so I can restore from the backup I made beforehand but I'll redo anything if someone has a fix. Otherwise I have to tell him he's stuck until his upgrade at the end of June.
Also, while on this connection it can't do anything on the internet or get OTA updates.
Might be a bad SIM card. Go to a different Verizon store and ask for a new one. This time DON'T tell them it's rooted.

been searching for 10+ hours and no luck or solution.
i was on gummycharged ep1f/ep1h rom and everything was working fine until today.
i don't know what triggered it, but my phone just restarted and then lost all signal.
after searching and looking at phone info, i found first line under baseband version shows "unknown".
tried flashing to every possible roms out there using odin and it would not bring the phone back to life.
funny thing is i have no problem w/ 4glte service, which allows me to surf and download but no voice service.....
do i have no choice but to go to verizon for replacement phone?
thank you.

yeah I'd take it into them, sounds like some hardware got fried.. however I'd probably try to flash a froyo rom for whatever good it'd do, if they somehow can check baseband and it shows GB your warranty is void and they will not fix or replace it
blazing through on my VZ Droid Charge 4G
found this over in the Galaxy s 9000 forum (wc8 posted it)
Mine now works fine
so what was the cause - still no idea
so what did help - rebooting the phone couple of times without the sim inside
heads up !
worth a try and not my fault if something blows up...
Begin minor rant:
Isnt it sad that we (everyone including devs and XDA as well as casual helpers like me) have to put that final line in there so they dont get blamed/flamed if things get f'd up?

Had the same problem with my Fascinate. After a flash I lost all 3G and phone capabilities. What I did was reset my phone line with the esn of an old phone I had lying around. Go to this thread. It will show you what you need to do.http://forum.xda-developers.com/showthread.php?t=1051543. I took mine to Verizon, and also spent hours with tech support and, to no avail. This esn swap did the trick. Good luck.
did the stuff you were flashing include the radios? like this one?
http://forum.xda-developers.com/showthread.php?t=1172182
or this thread?
http://forum.xda-developers.com/showthread.php?t=1111486
yes, all the roms i flashed had full radio from ED1, ED2, EE4, EP1F
none worked....
i'll try to search and see if esn method works that someone mentioned above.
keeping my fingers crossed....
currently, phone is @ stock ee4 unrooted w/ no baseband for cdma radio.
if anyone else is having same problem, do not run esn swap!!!
it will cancel your unlimited data and there is no way to bring it back.
thank god i read it before i tried it....
phone still no go with unknown baseband.....
HELP?!?!? PLEASE?

i called Verizon and had them do it over the phone. In other words, they moved my line to a dummy ESN on their end and some random number to my phone and then switched it right back, all while my phone was off, so when my phone was turned back on it got re provisioned on their network, which fixed my 3G data issues......but i dont think this is the OP's solution. When i had that problem I had phone service, just intermittent or no 3g data is all

You won't lose your unlimited data unless you switch to an ESN that is not a smartphone. I have switched my line a couple times and still have unlimited.

well if you are stock ee4 unrooted I think you are golden. Take your phone to verizon and have them deal with it.

I am not sure abotu this (not saying it is wrong but I never tried) I say take the 20 minutes on the phone with VZW and let them do it...
UPDATE
took it to verizon store twice, got sim cards replaced twice at two different locations.
still no go, rep recommended me to contact replacement center.
talk to tech for and hour trying to figure it out,
the tech announced that my cdma radio is fried.....
so i asked when i'll get the replacement and he said sometime on tuesday.
and i asked if i could use my really old LG non-smart phone for time being and he said i'll loose my unlimited data and moved to 2gb tiered data plan...
so i guess i'll be out of service until tuesday....

Hey I believe ya, I am just in the better safe than sorry frame of mind when it comes to the unlimited data structure. It does make sense though since i did switch from the fascinate to the charge without losing it
they told me this will only work if you went from smart phone to another smart phone.
however, if you went to non smart phone and then smart phone, you'd lose your unlimited plan.
I'm surprised this couldn't be fixed with a software flash. I came from a Samsung Epic and this was a regular occurrence on at least one of the Gingerbread leaks. Happened to me at least once - used ODIN and reflashed the whole shebang (full TAR with modem) and got it back up and running.
i wish there was an easy fix like you said.
then i don't have to wait for them to send me replacement device and also saves me from hassle of reapplying invisible shield. the maximum protection kit is pain in the ass to apply.
i've flashed with every single rom+radio out there in many different order with both odin 1.3/1.7/1.8 and samsung pstlite.
i've also tried flashing radio only and still no luck.
Oh boy. I've done something ..interesting.. to my new nexus s. Could you guys help me?
Okay, So I've been running miui for about a month now, and today I decided I will try the oxygen rom, along with a new radio (K3B). I flashed the radio over miui and all was fine.
Next I wiped and installed oxygen. No service. I couldn't even view available networks. I had a play around with the service menu (*#*#4636#*#*) and changed regions etc, but no luck.
The next thing I did was to try and revert to stock, by following the unlockrs guide (http://theunlockr.com/2011/01/20/how-to-unroot-the-nexus-s/). This seemed strange to me, as it was only a nandroid backup. Now I'm on 'stock' with no cell radio and a small wifi only tablet.
So, my real question is, can I fastboot or ODIN back to complete stock (radio, system, recovery, etc) or are there any other fixes for this problem?
Thanks! I'm desperate :S
Which Nexus S you got? Which ROMs you flashed exactly? Which radio did you flash, never heared of KB3b?
I'd assume you have a i9020T (since you used the GRH78 nandroid backup)? Then you could use the ROM in my sig to flash back to stock.
However, I never flash any nandroid backup that isn't my own, especially if they are crossing release numbers, eg 2.3.5 to 2.3.3.
I have the i9020T, flahsed the XXKB3 Radio (see here: http://forum.xda-developers.com/showthread.php?t=1116884).
I don't think flashing back to stock helps too much
Go here and get yourself a flashable full ROM for the i9020t, it will include a fitting radio (and a stock recovery). Remember to wipe everything before installing the ROM via cwm recovery. I'd also format stuff in "Mount and storage" (except sdcard for obvious reasons ).
Tried that. No success. I also used ODIN to revert to stock again. No success. Tried all the radios available for i9020t, none of them work.
My IMEI is intact still, my baseband /should/ be working, I really don't see anything more I can do except assume its a hardware issue. I'll give samsung a call now and see what I can do. Thanks for your help.
Maybe your carrier banned your IMEI for w/e reason.
Sent from my Nexus S using XDA App
I've tried multiple sim cards, and even if my carrier did block me (why would they do that?) I would still be able to at least view other network operators (and mine) in the Mobile networks menu.
Well multiple sim cards NOT working in your device could mean your IMEI is banned. Carriers block IMEIs for several reasons, stolen phones, contract abuse, carrier crossing, unpaid bills, etc etc.
Contact them and ask. If they didn't block anything you're still one step closer to solving the problem, next step exchange the SIM card, final step would be to contact Samsung and have them check for faulty hardware.
I'm starting to think thats the case.. My original sim card is dead and won't work in other phones now.
What I really don't understand is why they would blacklist me. I've been with my carrier for two years, since they started up. I'm a prepaid customer, so no unpaid bills. My phone is brand new, purchased it at Best Buy in the US four weeks ago
Maybe they were mistaken? I'll call them later in the day.
Ugh. I talked to my service provider, they said they couldn't do anything and were very unsure. They handed me over to samsung, who were unbelievably unhelpful and told me to turn my phone off and on, and that they couldn't do anything more. Just sent an email to my service provider hoping I get someone more 'higher up' who can deal with it.
Hi everybody. Hopefully I am posting this in the right section. I have a Tmobile G2x running CM7 nightly 201. I purchased the phone new (ebay) a couple of months ago. The phone has run relatively smoothly since CM7 installation, until yesterday.
Then, suddenly stopped connecting to the voice, data networks. It will connect via wifi, but would not connect/register for data or voice. It is driving me crazy and is now essentially useless. I have tried to reinstall CM7, I performed system restore to stock rom but the problem persists. It must be an issue with phone since my sim card would work in a different phone, and other sim cards will not work on my G2x.
I have tried to use GetRIl to change baseband. I am now running M6600A-SCAUNTZ-2.0.9720T 1 and I am back to stock rom.
Not sure if there is any way to solve this issue. Should I just resign to buy a new phone? Any solution/setting that I am missing? Can I send back to LG/tmobile a phone which has ClockworkMod Recovery on it? Sorry for the many questions.
You said you went back to stock rom, but did you do a complete restore??

Have you tried a full wipe?

did you pay your phone bill?
Thanks for the quick reply. I tried restoring to original stock, then erasing all user data. I also tried several times wipe data/factory reset from ClockworkMod Recovery menu. Unfortunately no solution.
Wow, have you tried working as a comedian for a living?
May not be what you want to hear, but it is possible the seller sold you a stolen phone and it has be blocked. You may want to go to T-Moble and have it checked out.

Thank you. That would at least make sense and I would report it to seller/ebay.

This, maybe. Also try getting a new SIM card from tmo.
Also, check the IMEI before buying used phones. Even if your phone doesn't happen to be stolen, this is still a good idea.
Thanks. The phone was new from a 100%, long-time Ebay seller. Is there any official website to check for validity of IMEI?
I am going to check with T-mobile but there is also a thread showing other people with similar issue. http://forum.xda-developers.com/showthread.php?p=17660686
Unfortunately, no solution posted. If anybody else has comments/alternative solutions, they will be greatly appreciated.
Hi, I bought a NS4G off my friend yesterday, and the first thing I did was return to stock 2.3.4, and update to 4.0.4.
I plan on activating this phone, but when I tried *2, I got "Welcome to Verizon" activation procedure. I checked out my PRL's and it's P:52690, which I found out was PagePlus, I did *#*#786#*#* and reset the RTN.
Now, I just need stock PRL/NV images, or whatever else I need to do to get this phone back on Sprint.
Never flashed a phone before, bear with me.
EDIT:
Figured it out, flashed back to Sprint.
Hey guys.
I just got my i535 Galaxy S III a few days back, and decided to root it. Paranoia wasn't for me, so I tried CM10. Somewhere along the lines of that, my 4G stops workings. Luckily, I already backed up my IMEI.
I've been trying for a few hours to fix it. I already used the following methods of "fix":
Restoring backup from CWM
Going back to (rooted) stock,
Changing my Mobile Networks settings around,
Phone Info (Couldn't honestly find out what to edit in there, or if anything WAS editable),
restoing IMEI
From what I can see, I have my IMEI, MEID, and phone status reads: "Normal". Yet, when I look at my bars, I get 3 of 3G, instead of my usual (and what my other galaxy S III devices are running currently.)
Samsung's firmware mirror site is down at the moment, so I haven't tried that last resort before returning to Verizon, but do you guys have any thoughts?
Thanks
I have a similar issue - except my phone does not recognize the verizon network. I was rooted with CM9. i've since replaced the SIM and flashed to factory rom. I am seeing my IMEI number, so I don't think that's an issue (right?).
I took it to the verizon store and they want to trade it in, which i am fine with
My biggest concern is removing any trace of root.
I had the same issue when going into cm9, got a new sim yesterday and I got my 4G back.
I'm in the same boat. Just gonna get a new sim card and hope that fixes the issue
