[Q] Stock, not detecting my network anymore - Samsung Galaxy S (4G Model)

Hi, sorry if this is promoting clutter but I've scoured the internet (google, wiki, searching these forums and others) and haven't been able to find a solution.
Some background:
Phone: Samsung Galaxy S 4G
Running stock GB 2.3.6
A couple months ago I woke up to find my phone would not pick up and connect to the t-mobile network (it constantly displayed (searching) on the dropdown menu). After trying many things it would sometimes randomly connect to the network and allow me to send/receive messages and make calls, but it doesn't last.
Things I've tried:
Rebooting
Going in and out of airplane mode
Unselecting and re-selecting use packet data
Manually searching for mobile network operators (it recognizes that there are available AT&T and T-Mobile networks, but when I try to connect to either it fails)
Performing a factory-reset
Rooting, Flashing to a different GB ROM
Factory reset, then flashing to Slim ICS instead
Performing another total wipe/reset, and now I'm back to stock.
EDIT: Sorry, I've also gone to the T-Mobile store and switched SIM cards to no avail.
I used the new SIM card in a new phone (another Samsung Galaxy S 4G) and it works perfectly fine, it's just this phone.
If anyone could give me any other ideas I'm all ears, and I appreciate any help lent in advance.
Thank you, and if you need any other information please let me know.

And you have checked your apn settings? You have an imei number listed in the about phone?

Wifi, gps, bluetooth work at all? calling or txting or data or nothing?

Heimdall one click and re-check

Sorry for the late reply, I've been on shift.
Champ: My APN settings look correct (registered on T-Mobile US, epc.tmobile.com), and I do have an IMEI number listed.
Geto: Wifi works. GPS works. Bluetooth I haven't tried. Calling/texts/data doesn't work at all.
Itzi: Just tried heimdall one click with no success =( Picks up on the T-Mobile network (instead of saying (searching)) but doesn't display the 4G/3G/etc. next to the service bars and won't text/call.

Good be a bad chip. I'd call Samsung and talk to them. They made the phone and if your still under warranty they will do the right thing.

Could be a defective modem 'cause it gave you random connections. Are you under a contract with T-Mobile? If so, they will replace it for free. Although u have to pay the replacement fee of $25. Call them.
Hit the thanks button if it helps. It's my motivator to be more helpful.

I was afraid it was a hardware issue... Thank you for all your help, guys.
I'm not under warranty nor am I under contract. Any chance they would still replace it?
Also, if not, is there anything you recommend I do with this phone? (sell it, use it for something else, etc.)

Out of warranty they will still fix it but the price may be more than the phone is worth. Its still worth calling them to find out. AS Far as other uses the thing makes an incredible mp3 player. The Wolfson DAC in it is way better than most. In airplane more just playing music I can get 20 hours plus out of this phone. Which is pretty sweet.

If you bring it to T-mo lab, Heimdall back to stock without root, or they will blame you for this and get lazy on analysis...

T-mobile voice comfirmation

Just spoke with the tech support department at tmobile... They say the tab will do voice but it has had the software removed from the build... Can someone please pull the phone apk and the phone utility apk from a euro build so we can test it on wednesday when it comes out. Hopefully this will solve the issue of no voice. He also confirmed it has all for gsm radios onboard and will work with the standard android data plan... Heres hoping...
Sent from my Dell Streak using XDA App
Hells yeah!
XDA GO GO GO GO GO GO !!
Just came back from demoing the Tab at my local tmobile store. It does use a standard sim. However the update is this: in the apps management screen, it seems that the only thing missing is the actual phone apk. The phone utility apk is there and the contacts apk is there. It looks like we just need the phone apk and then possibly the contacts merge apk to get voice enabled. Anyhow, the phone is being released at 11am pst tomorrow in my town, mine is on reserve so I will have it by 11:05am pst. anyone who wants to guide me into activating voice on this baby, send me a message and i will be happy to assist with trying some methods out.
I will need to try the following apk's from the euro version:
phone.apk
contactsmerge.apk
oh, the local reps looked on the computer and said that this device WILL require a webconnect data plan, not the unlimited android. There is a work around though... with voice enabled, you can call tmobile and ask for a tech support supervisor, open a trouble ticket and request an engineer to change your device ip range to that of a smartphone... then data and voice should work together. I had this problem on my aws version of the dell streak and it fixed it using unlimited voice and unlimited android data plans.

i would appreciate any help you can give me. i tried pushing a modified phone.apk that was on this forum but with no success. i put my nexus sim card in there and when i launched my browser i was able to go to google.com and do a websearch. but when i clicked on a link i was sent to a tmobile site with a 404 error. not the same error that you get when u try to use a $10 data plan on a mytouch (it says u need to upgrade ur plan). it was an actual 404. but i am actually using the $10 data plan on my nexus, but since i was able to go to google.com i think theres away around this.

Why don't you just flash it with the EURO firmware??

Is it known for sure that the hardware is identical? If not, I'd say that might be a good reason. This could lead to reversed buttons, inability to get into hardware, recovery mode, etc. Also, the system dates would likely display backwards from from the US does it too. Just my 2 cents.
It seem a much better idea to just pull what you want from a system dump of the euro firmware.
can someone please post these apk so we the U.S can work on calls thank you
I second that request... the guy I was working with yesterday and I were stopped at loading the phone apk as well...
Does anyone know if anyone else (anywhere) is working on a fix? I've googled and googled with not much success.
jdmadonna... all of the Euro firmwares are posted on samfirmware.com ... have you checked there?
I loaded the phone.apk onto the tab after rooting it with z4root. Then using root explorer. It loaded fine... but then a really wierd thing happened. The tab vibrated every couple of seconds and kept showing the message : android.phone has stopped working. This kept happening over and over. Finally I turned off the tab, and rebooted... that's when all hell broke loose... lost the network provider and lost the whole baseband on the tab. Nothing would bring it back... bricked the tab. I took it back today, will wait for more to come in stock and for a REAL developer to figure out how to bypass this problem... sorry guys, I tried... and it killed the tab!!

Sorry you bricked your tab :|.
I wished you would have tried to flash the Euro firmware before taking it back to see what happens as it was already bricked.
If the euro firmwares are flashable on the T-mobile model, voice should work just fine.
Geez jdmadonna.... WHAT a drag... I admire you trying...
I'm hoping some developer somewhere is working on this...
I made the decision today that I'm just not going to pay ~$1000 for the Euro Tab in order to get a phone... I love the tab.... but $599 tmo off-contract is all I can justify... I can afford more, but will not spend more.
So... if we can't get the t-mo working with phone... it's going back...
effing greedy US carriers who didn't want to "cut into their smartphone sales"...
thx again for trying... will they replace it?
btw... was that the Euro version phone.apk?

You didn't brick your galaxy tab. All you had to do is push the original files back. I pushed a modified phone.apk and got constant crashes. I made a backup of the original, you should always make a backup.

[Q] Unknown Baseband???

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.

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.

[Q] Bought used, this is a very hard puzzle

Hey I bought a used Samsung Galaxy S 4G for $110, and wanted to make android apps.
I know a lot of programming stuff, but it doesn't seem to help me much to fix this phone.
OKAY THE LIST OF PROBLEMS/SYMPTOMS
-Doesn't register SIM cards, doesn't even notice them! I can't use the phone like this.
-Stuck in airplane mode if I put it in, requires factory reset to get out of.
-Back speaker for music doesn't work. Earbuds work.
-MicroUSB port is fine, charges, but usually won't show up on my computers. It gave me a "USB Malfunction" error two of the times.
-IMEI and baseband show up in phone as "Unknown."
-Voodoo lagfix is installed? My buddy said this phone isn't even supported.
WiFi, MicroSD and apps all work, it seems fine otherwise. Factory resets do not fix it! Even the power+volume buttons one, where I find the voodoo lagfix crap.
I bought it from a girl, and I think her derpbag boyfriend maybe flashed Vibrant's firmware or did something wrong to it. I might have been ripped off.
Can anyone help me out? Know what to do? I will appreciate it!
First thing you can do is follow the second link in my signature and flash with bootloaders. Missing IMIE is a problem only ODIA can fix.
How do I do this without my USB port connection option?

YES You were right, I followed your guide and got the phone to do new things.
It asked me for a SIM card and I haven't put mine in, but the IMEI number is BACK and ready. I didn't flash bootloaders yet, but should I still?
The phone's speaker still doesn't work, maybe I can't save that.
I got lucky, I tried plugging it in maybe 10 times I finally got it in download mode, so that's awesome.
Should I flash bootloaders? And what is the next step to possibly fixing the speaker?
I will probably want to root then unlock to use for my AT&T. I won't get a data plan tacked on this way, right?

If you're already on Gingerbread (You can check by going into settings > about phone) then you don't need to flash bootloaders. If you're on Froyo, then yes flash the bootloaders.
If you want to unlock your phone, click on the "SGS4G Unlocker" link in my forum signature. It'll get you your unlock code, which you can use after you insert an AT&T sim into your phone.
I'm not sure whether they'll tack on the data plan, but if AT&T works like T-Mobile, they'll require customer authorization to add any features to your account.
Well hey AWESOME.
I did flash bootloaders, didn't notice any difference.
THEN I went and tried to unlock it, the sdcard could only be read and not read/write from the Terminal emulator.
So I rooted it even though the root checker said it was rooted, and I did somehow have "superuser" already installed.
Now I also unlocked it afterwards, and it's working with my SIM and phone contacts. I sent a text and it's too late to call anyone today, but I'm expecting it to work fine tomorrow.
Your guide was fantastically helpful and easy to follow. Thanks a lot man!
The back speaker doesn't seem to work still, but I'm still counting it as a victory.
I recommended flashing bootloaders as a precautionary measure. Yes - you were already rooted. Glad you are up and running.
Maybe you can try replacing the loudspeaker if you cannot get it to work:
http://www.globaldirectparts.com/Sa...-T959V-Loud-Speaker-Module-p/smsng6103100.htm
As for the AT&T thing, they can't find out that you are using smart phone since they don't have T-Mobile's list of IMEIs, so they won't automatically charge you with a smartphone plan. Also, if you previously had a 3G data plan with that AT&T SIM card you are good. However, if you don't, you need to turn off packet data and roaming at Settings --> Wireless and Networks --> Mobile Networks.

[Q] T-mobile on skyrocket

I was wondering if anyone could help me figure out whats going on. I got the tmobile\walmart plan for $30 that includes 5gigs of data a month at 4g speeds. My phone is unlocked and with the tmobile sim I am only getting edge speeds right out of the box, so I tried flashing various t989 modems with no luck. I would either get edge, or when I would try to goto apn settings it would say no sim installed. Right now Im using the Telus Kj3 modem, and still only getting edge. I am right in the middle of St. louis so I think getting tmobile 4g shouldnt be a problem. Also im on stock 2.3.6 rom. Any ideas?
Read the thread about this. Search

Ive been searching for two days, and have read about 35 different threads spread all over xda and the skyrocket forum regarding this problem and have tried a hundred different things. I need someone that has successfully gotten it to work that can point me in the right direction. Your advice of "search" does me no good. If I had found the answer, I wouldn't have created a new thread about it.

Well apart from the search advice ... it's too simple
-unlock the phone with a purchased unlock code
-put T mobile SIM
-flash T Mbile blaze 4G radio using ODIN
-in Android set up the T mobile apn settings
It should of been simple but it wasn't. After days of trying different roms and modems, and reading every page on it, I had no luck. So I invited someone over with a tmobile 4g phone, and I put my sim in it, and that phone didnt get 4g either. Finally figured out it was on tmobiles end, called them, and they fixed the issue. Also, after flashing the blaze modems, my phone said no sim card. The telus modem is the one that worked for me.

And it's always a good thing if somebody with a problem to disscuss here , would come back and say what worked for him/her so it can benfit the others
I had my wife call. I did not need a new sim. The first tech couldn't figure it out because he had her do things like take the battery out, and power cycle the phone which of course didn't work. So he escalated to a higher tech, which eventually tried "refreshing the signal." Wife said right after he did that, the 4g symbol came on my phone. Sadly though, Groove ip and talkatone don't carry a conversation to well while driving, even on 4g. I think I will try skype, and if that don't work I will have to switch my plan to something with more minutes.

It sounds weird I know... but kudos to the tech guy. Whatever he did, it worked. Rather it be that, or something else he tried.

[Q] SOS: Help with breaking Verizon SCH-I535 to be fully functional on T-mobile

Hey everyone and thanks for taking the time to read this,
So the story goes as so: After doing some research couple months ago about the capability of the Verizon Galaxy S3 to work on T-mobile, i purchased it, and got it to successfully work on T-mobile(texts, calls, wi-fi). The problem is, i just recently upgraded to include a data plan, and i cannot access the internet, despite taking my phone to my cell phone dealer and contacting T-mobile.T-mobile even sent me a guide to do a mastery reset to factory in hopes to solve this problem, only to tell me afterwards that the phone version SCH-I535 is a "verizon locked-software" and i won't be able to set up an APN to work on the T-mobile network. This was all due to the fact that i was not able to set up a APN for T-mobile, and every time i tried to access it through setting, it brought me to a blank black page with the only option of "Reset to Default". After reading other forums and talking with some people, many have suggested i take this issue to XDA to find a solution.
So, here i am.....Does anyone know if it is possible for me to break/root/ or whatever it is called so i can successfully access the t-mobile network on my phone? Preferably an easier guide since i am sort of a newbie at this sort of stuff.
Thanks again for reading.
