My Samsung Galaxy S can not connect to 3G
GPRS or WIFI is ok. Of course, APN is ok. Just when I switch Network Mode from GSM only to AUTO GSM/WCDMA or WCDMA only, my SGS looses connection completely, only WIFI active. Can not even use the phone to call or be called.
After several new Odin Rom flashes, send it back to Provider to get it repaired. Got it back with statement they replaced "IC Power Amp". Yes: It worked for 3 days...and now again no UMTS / 3G, phone only works when I put Network mode on 2G only...
Shipping it back takes another 3 weeks... I've been asking now for new phone... no luck yet... And wondering: does anybody here have an idea?
this is new to me
but it's a very interesting case indeed
Yeah, thanks for the reply though. I was afraid I have a special case on hand. Will keep posted if there is any progress.
I found the offending chip on Phonewreck, ( phonewreck.com; samsung-galaxy-s-teardown )
I can not believe the same chip fails twice. This must have some other cause..but what ????
Anybody heard of this chip (or problem) before? Am I really the only one out there?
Was fiddling around more. I got when I tried to apply update.zip, after pressing volup&home&power , a red error message:
multicsc : can not access to /system/csc/XEN/system/
Can this have anything to do with the problem ??
Still no...?
Oh, is it that nobody has an answer... or nobody reading this? I am still looking for a solution...
Will try to Reset phone to factory with the 3-key combo and ten reinstall the official Frodo. Maybe... you never know. It remains weird. Somehow I refuse to believe it really is a hardware issue... twice the same while about nobody else seems to have this???? Hmmm...
Nope, Frodo runs fine... except for the 3G issue. Still when I put it on anything else than GSM only, it will loose all connections...
I have tried to search the forums for answers, but I keep finding a lot of non-definitive results (and many reference FAQs for the Galaxy S phone).
I have a T-Mobile Galaxy tab that is running stock T-Mobile Firmware. I also have an active AT&T SIM card via my job.
I have unlocked my tab and created a custom APN that allows me to use the AT&T SIM on EDGE.
I understand that AT&T and T-Mobile use different frequency bands for their 3G, but I am unsure if these frequencies are completely unavailable on opposing characters or if they are just disabled in firmware/software.
Is there a modem.bin (or other firmware) that will allow we to flash a T-Mobile Galaxy Tab and use an AT&T SIM for 3G? If so, is there a firmware to revert it back if there are issues?
I don't really care about voice (at the moment) but it would be nice to use the unlimited AT&T 3G card instead of paying month-to-month with T-Mobile.
Why dont you unlock and try? I know rotohammer posted instructions on how to unlock. He also posted a complete package to flash to stock.
NO, it's not possible!

Do'h!
Is is a hardware or a software issue? i.e. can I ever hope that someone might figure out how to do this?
I have only had my tab for about a week; If it is never I may re-consider returning and purchasing one on from AT&T...
clubtech posted the modem.bin for AT&T here.
http://forum.xda-developers.com/showpost.php?p=9342507&postcount=47
If you're willing to test it, please let us know how it goes! I'm interested, but I'm scared that AT&T will screw up my current plan. They've done it before - swapped from iPhone 3GS to Palm Pre Plus, then back to iPhone 3GS - found out they switched to unlimited data, and didn't work on my iPhone. I had to call to have them switch back to an iPhone data plan.
Also scary - stuck a dumb phone SIM into my iPhone -automatically added iPhone data plan.
I'm grandfathered into the unlimited iPhone data plan, and don't want to risk it.

You can create a custom APN profile and use almost any AT&T SIM in an iPhone. Get on WiFi with your iPhone, and open http://www.unlockit.co.nz/.
My AT&T work SIM is for a blackberry, but I have been using it with my current and prior iPhones with no issues (I have helped a few others in my office do this as well).
I am hoping to be able to do the same with my Galaxy Tab.
Thanks for the link. I will try the modem.bin in a bit- and may even go and do a full-blown AT&T firmware at one point-but I am trying to make sure I have a chance (i.e. the radio frequencies are available) and a way to backout if there are issues.

The thing that scares me is that AT&T actually messes with your plans according to the device you stick your SIM in. Now that's BS, because if I ever want to stick it in another phone to test it out, then put it back in my iPhone, I may loose my unlimited data plan and end up with the 5GB data plan. They don't offer unlimited anymore. I'm grandfathered in.
Before they took it out, I was able to swap devices willy nilly. They were able to switch from plan-t0-plan, and I don't care because I can always get back to the plan I wanted. Not any more!
Let me know how it goes. I'm interested in flashing mine, but not sure how to go about it.
Well, curiosity got the best of me, and I put in my iPhone 4 SIM into the Tmo Tab. It works! Just make sure you have the APN set up correctly. Edge only. I have no idea how to flash the modem.bin file. I'd like to find a way to back up my Tmo modem.bin first before I try the AT&T one.
Nope I've tried *#2263# and changing the apn modem.bin still got edge.
I went ahead and tried a few things- and here is what happened.
I flashed with the EU firmware and the Bell Modem (via the RU firmware and repartitioning) and ended up only getting a GSM signal (wow- that make me nostalgic of my old Nokia 3650 days).
I messed with it for a while and eventually flashed the AT&T stock firmware. With this I was able to get EDGE, but the whole system was buggy- such as the startup screen was blank until it completed and I pressed the power button.
I trief to re-flash with T-Mobile stock firmware and I was stuck in EDGE; no 3G available.
I tried to re-flash with T-Mobile stock again and I totally bricked the unit (note: don't rename the folder containing the firmware while you are in the process of flashing!). It was uber-dead; it wouldn't power on, no recovery mode, connecting to a PC didn't detect any device and the charger wouldn't even light up when I plugged it in.
I ended up returning it to T-Mobile as I had only had it for about a week. They gave me a credit minus a $10 restocking (called post activation) fee. I may look around to see if I can find an AT&T Samsung after the holidays...

Ouch! yea, you wouldn't want to change the name of the folder you're flashing from. >_<
For those who flashed their Tmo Tabs wth the AT&T modem.bin file and still getting only Edge, did you make sure you're set to connect to GSM and WCDMA?
When I inserted my Tmo SIM back in after playing around with AT&T, I also had Edge only. I found out that I left it on GSM only. Doh! Set it back to GSM and WCDMA, and I got my 3G back.
I'm hoping that's the small detail that is preventing Tmo Tab users who flashed to the AT&T modem.bin.
I still haven't found the instructions to flash the modem.bin though. All the guides I found are about flashing entire ROMs with the modem.bin, not just the modem.bin itself with the stock (but rooted) Tmo ROM. Otherwise, I'd try it myself. Also would like to know how to back up my current modem.bin before I start experimenting.
On a positive note, AT&T hasn't messed with my granfathered unlimited iPhone data plan yet. *cross fingers* Makes me feel more confident to try it again on my Tmo Tab.
Has anyone succeeded in getting both data and voice? I have an iphone unlimited data plan and a t-mo tab.
Where are you guys getting the ATT rom from and what .pit file are you using.
I am trying to go back to the ATT rom but it boots blank after trying a couple posted here.
Thanks
I too have a tmobile SGT and I would very much like to use it on at&t 3g. I have sadly yet to have found a definitive answer as to whether or not the hardware is capable of doing so? Shouldn't it be a simple matter of flashing the at&t modem.bin onto the tab so that it can handle the appropriate 3g frequencies?
please advise!
Definitely NO. Hardware is not compatable. There are many definite answers, and a few idiots. The radio frequencies don't match, and no rom or modem file can change that.
So as of saturday my unlocked TMobile Note 4 stopped working as a phone, and won't let me make calls.
Information:
-Was on Dr. Ketan L3 version of his rom when it stopped working
-Using the N910T on AT&T
-IMEI is fine and not damaged, both numbers match (using *#06#)
-It shows bars, but when I go to make a call "Not Registered On Network"
What I've Done:
-Flashed Stock Firmware via Odin (Autoboot, and F.Time Rest checked)
-Factory Reset after odin flash
-Checked APN
-Set on LTE/WCDMA/GSM
-Searched for Networks, finds them, but when I choose AT&T it takes forever and then finally kicks me out and then in notifications, I get the "Not Registered to Network"
-Did the remove the battery thing, and removed sim
-Went to AT&T and got a new sim, worked for 1hr (sporadically) and then went back to "Not Registered on Network"
-At the store I was on phone with AT&T tech trying to troubleshoot the problem and that is when it was working shortly
-Called T-Mobile and checked to see if they blocked my IMEI number, nope they didn't, couldn't help me out further than that
-AT&T was showing that it was a Note 4 so not having that coming up as a Blackberry issue that some reported, so that's not it
-*#0011# shows service limited, but it is unlocked and everything is fine, the IMEI is good, and all is well but the limited service
-Put it in Airplane mode and woke it back from there after 5+minutes
-cleaned the connectors on the sim (new sim anyways so shouldn't really need them)
I'm running out of options, the only thing I can think of being the problem is that I might have started out using this phone on COD2, and when I flashed a COG2 firmware it didn't like that and so my phone's account settings didn't fully transfer.
Also I was messing around with the bands settings (*#2263#) what should they be on? Automatic, LTE/GSM only, or what?
Settings should be on automatic. One more thing to try is go for a drive with the phone, at least 5 miles from your house, and see if it does this when connected to other towers. I had this same issue years ago and it turned out to be a malfunctioning tower by my house.
If it still does it on other towers, then it may be hardware-related

Thanks, yeah it kicks in randomly for like a minute and then dies, I take it to my parent's house (about 10 miles away) and along the way I get a good signal, but then when I reach their house, back to nothing. I was using it just fine the week prior. I partially blame Dr. Ketan, ever since installing his rom, I had multiple issues. I since uninstalled it and tried going back to stock. Any idea on what a good "safe" band setting is? I have that settings set to automatic, but if there was a good "safe" band that would be great. A common LTE tower. Even when I do connect or get connected, I can't register on that network, my phone won't let me. I've tried that. The bars drop to zero. I damaged my antenna wire (white one) and I just replaced it with a new one I purchased, but the hacked together one seemed to be doing the same quality job as the new one is. It shows the signal, but as soon as you try tying it down to a network it rejects it. I was afraid that when I flashed the stock image via odin it removed the unlock, but it was still there. I just hate that now I have a $500 pda, when it was a phone and now i'm relegated to using a f*ing flip phone.
i think your antenna cable is damaged. the only way to know that is be close to a tower, and see if your work or not.
bought and replaced with new ones, I get full bars, in my bedroom, but apparently they're tied to Tmobile since when I try to register it to AT&T they magically disappear, but when I close the app, they come back at the same strength level. I can't register them to Tmo since the sim. Yet my phone is telling me it's unlocked (*#0011#), IMEI = PASS, 1;
I think the prob is due to the different frequencies.
Your baseband would not be tied to a rom(ie Dr Ketan) Unless that rom contains Modem.bin
Your apn needs to be att if that's your Sim obviously.
International version has a different chipset. .. I know it's not your case. .
But it's open to any Sim. ..
I can say this.. I have a N2 unlocked (tmob) I run an Att Sim it works but the sig is really spotty... COD6/ COG2 may not be lining up frequency wise with your att Sim. ..
Try rolling your baseband back even further. .

Any clue on to what i should use for best results? Like 850/1900 or 900/2100? What is a good LTE band? Where could I find a map of LTE bands used by carriers, I know how to get to that secret menu and manually change it to see if I get better results?

Well I would think automatic is out for sure.. the other prob would be after reboot the chipset will search for the default.. but I could be wrong.
I do not know what the numbers would be for band identification.
You may get lucky when calling Att and ask for someone in a higher tier. To give you some numbers for frequincies .
But you have ruled out hardware correct??
By putting a tmob Sim in????
Cuz I know you posted you did antenna work..
And I do know you said you get bars then it fades..
The fact it fades and doesn't lock into even a G band for example. Just leads me to believe the apn can't lock down based on the frequincie and the built in lte chipset...
It would be nice to just flash an att modem wouldn't it?? But don't even think about it.. lol you'll soft brick..
I wish I had a better solid answer you. You may just start testing those different bands and see if you get closer to a lock.

My Tricked Out N910P
But what could have happened that made it crap out like that since it was working just fine beforehand for 2 solid months on custom roms and what not? That's the frustrating part, I've been flashing different modems on my phone, but none have been successful. Apparently there are 3 different N910T, how do you know which ones to play with? I flashed N910T(3) bands, that failed, I did try N910A, obviously failed. Then I lost my IMEI number, got terrified, tried reflashing EFS in TWRP, nothing. Then reflashed COG2 bands, it came back. Is there an app on the Playstore that would definitively tell you if your network chip is damaged? I wouldn't know what to look for.
Have you taken apart the Note 4, what are all those contact points, are those antenna things? One of those were damaged, they're like folded metal spring boards with gold tips (same kind of thing that is used to install a qi receiver, same design). I took my tweezer and fixed it, but could that be the culprit, since on the surface, it seems like the network is fine. Works really well in WCDMA, but not much else. I was able to make calls using GSM only, but my signal was 1 bar and the audio quality was questionable, so I left it alone for 10 minutes on that hoping it would force a reconnect. This is frustrating, since I wasted $500 on this phone and not having it work after two months means now I'm back to a featureless phone.
Thanks for your advice thus far. Flashing different modems hasn't been working out well, I just wished I could remember what baseband version the guy had the phone on when I first got it? I thought it was COD6, it was definitely on Lollipop, but if it's a 910T(2) would I know, how would I know?
How do you flash NON_HLOS and modem.bin at the same time in Odin? I know Modem does bands, but what does Non-Hlos do? I thought i read LTE, so if those aren't in sync and on two different versions could that be the issue? I extracted them from the full TAR firmware files.

Heres
A simple method for COD6
And try odin 3.07
I need to think about this some more and get back to you...
This is a partial firmware.. it consists of the modem and bootloader COD6.
Also to rule out damage if you can get a T Mobile Sim put it in the device and see if it locks down a signal....

That was my next move, not having any real income but disability and little coming from that, I thought that was the next logical step too. I'll get a tmobile to go sim and try it see if it can't lock on to that, and see if that doesn't set it on the right path. Have you heard of other people having COG2 issues on AT&T unlocked? Maybe that was the problem, something there broke the connection. I don't know, but whatever it is, I can't thank you enough, you've at least given me more options to try that I couldn't think of on my own. I'll try that file.

Make sure you read the detail in if your device bootloops, to reboot recovery and flash the Rom.. if you want flash the Rom in the op that I've linked you to.
Wipe sys/dal/cach/data..
And flash it can't hurt.. [emoji16]

Got the sim card, $65 for that crap, and it didn't work. Called T Mobile customer service, explained my situation and how I was calling on another phone on another carrier and they insisted on calling me back on the broken not working phone. I guess I'm just screwed, and lost $500, which like I said, I can't afford to have. It's just so frustrating. I also tried the COD6 partial firmware, and nothing there also. I'll try t-mobile again. The only and last option I have, if possible, is to try to relock my phone and re-unlock it since there isn't any real way to tell if my GSM is damaged. I think my unlocked status got damaged when my phone upgraded to COG2, and since it's in that weird limbo state I can't use my phone. Do you know how to relock it?
Edit: When I look at my IMEI Number through *#06# it shows that the last two digits (independent of the actual IMEI number, since that matches everywhere) to the right of the "/" as 14, yet through "about device" it shows my imei version as 10. I assume that the 14 in the "06" screen is the version it's reading off the phone, could that be causing the issue? How would you even fix that? I don't know. but thanks again, you've been helpful.
Hey Guys,
FINALLY found a store with a 64 gb T-Mobile note5 and I return my original 32 gb with joy, to return home to find the Wifi is completely broken.
Just wanted to check to see if anyone has seen anything like this before. I'm just stumped. The T-Mobile store I bought it from told me to hold on to it as they don't know when they will get more Note5's in 64gb.
I have included a gif of the problem and I just can't find a single thread to point me in the right direction.
(Fwiw: I have reset it numerous times, deleted caches, even odin'd the original stock Tmobile Note5 rom to see if it was software and still no go. )
https://slimgur.com/images/2015/08/26/df7e0bc454a34434ac812c975a5bfda0.gif
It will stay connected until the moment I pull data from wifi etc and no matter what it just goes crazy like the gif. No matter what wifi network it is, even the T-mobile Store one was making it go crazy.
Anyone have any ideas?
I'm also having problems with wifi connection my my vzw 64gb however nothing like this gif

Can you keep a connection ? What issue do you have?
Hello! I Had my Blue Camo GS6 Active 64 Stolen last sunday, Bought A White GS6 Active 64GB Model to hold me over and its in real good condition. But its Network Unlocked and noticed the setting on my 32GB Black And my old Blue 64 phone were set to GSM/UMTS. This for some reason is stuck on WCDMA? I Don't even see a GSM/UMTS Option and was wondering what i should do here?
I Did a few system updates thinking it may automatically work but whoever had the phone before must of changed something, even a Factory Reset didn't solve the issue. So i get the phone in the mail, power it on and everythings good no SIM yet but it had 4 bars, Pop in the AT&T SIM and restart and bam No Signal at all. I Changed it to GSM And get nothing. I Notice if i set to LTE/UMTS When i'm up the road it actually pops up 4G LTE And works too! But i get home and Poof No Bar. Its probably cause it usually does get knocked down when i walk inside to 4G But never no bar.
Anyway i can Flash a Stock OEM Modem? Or a way to force the Network settings to Reset to OEM? Had this... well that GS6 Active for 3 years never had an issue but mine was AT&T Network Locked i never unlocked it. This is Network Unlocked and notice a lot of what seems to be Foreign Networks? Network settings I've never seen before that's for sure.
Help will be appreciated!
Really need this to just work by Monday and AT&T Support sucks lol! Best buy couldn't help me, 3 AT&T Stores couldn't help me cause they don't sell it anymore and i didn't buy from them. But i know its fixable i mean i get signal if i flip around to the WCDMA Setting when i'm home, And before i walk outside i hit LTE/UMTS and i do get a 4G LTE Signal when i get up the street. but i'd rather it Automate like it did before so i don't have to keep doing this.
Yeah this sucks, Like Mint White 64GB S6 Active. Just this i didn't expect. I've Switched sim cards back and forth, took the sim out and tried to change the band but that doesn't work. I've gotten to the Network System menu and put everything on Auto. I Have it set to LTE/UMTS and i get nothing, i take the SIM Out and restart, 4 bars are there. put the SIM In and Boom no signal. I've tried to change the GSM/UMTS Band to Automatic but it just says Unsuccessful. But i have that feeling if i can get it to say Successful it will work.
Anyway to use my laptop to connect via ADB And Force the band to change to auto? Or anyway to get it to stick to Stock settings? I Still suspect whoever had this before did something to the Radio and Network settings and i can't figure it out for the life of me. AT&T sure won't help me lol! And Samsung just wants me to bring it to a repair shop. While i was actually at a few repair shops around here and they know nothing about these.
It's the only phone i'm comfortable with. The S8 Active is ok but without physical buttons it doesn't really serve me like this did... and i don't really care for Bixby button can't be customized. Also noticed Otterbox doesn't make Defender series cases for it so i'd have a bit of trouble getting a beefy case on it.
Ahhh.... i get some signal in WCDMA Preferred. Fixed a SMSC Issue so text's go out and i receive them if i move around a lot.
Signals still bad not like it used to be. Why do i get a Signal On WCDMA But not GSM Auto Or LTE/UMTS? Is there anyone that can help me get to any advanced network option's or a way to change the Band to Automatic? I Try to select Automatic Band which is the default i believe and it just says Unsuccessful.
Have you tried just refalshing stock rom???
I know you already have done this but sometimes it doesn't work first time(few have mentioned issues that took several flashes to solve it)
The reason folks are not replying is quite possible know one has any idea why this has happened.
I had an s6 Active that everything worked other then 4G and nothing worked.. It was a factory refurbed and Unlocked. And no matter what I did it simply would not worked... I returned it and go a replacement... It suggested it had been damaged internaly in someway..
Can you return yours for a replacement/refund???
Sorry am not actually able to help.
regards
Lohtse
I might return it. I figured out why messages were not sending i messed up the smsc settings lol!
Very unique issue here i see 4G pop up and i get calls and data flows. Sometimes 4G LTE magically appears and everything stops working till 4G shows up.
Pretty hard to find this GS6 Active in 64GB anymore.
If i take my sim card out and dial *#*#2636*#*# i think? Or it might be *#*#0011*#*# it brings up network options. I notice if my sim cards in that menu shows up empty. Something maybe wrongly set in there but not sure how to tell. Never found a way to successfully set the GMS/UMTS Band. And with no way to really root it or change anything through the pc is probably going to make this even more difficult. Phones in great condition though i dont think theres damage i believe its a network setting somewhere i missed... or at&t sucks lols! Every sense i got robbed on the 18th its been nothing but a big problem getting a phone working again.
Reflashing stock rom? Like Android 5? Its in Android 7.0.1 now. Id be interested in doing this but going back that far is spooky i dont wanna destroy it. Ive seen people say its possible and others say its not possible to go back.
That would probably work though! When i got my S6 Active Camo Blue 64gb New it was Android 5.0.1 and i think more network options were available. Then in 7.0.1 they all disappeared.
Never had issues on that phone i can't believe it was robbed from me. Not like i dropped it or lost it either it was robbed from me! Police did nothing even with the fact they threatened to kill me and everything. Police did nothing... and after 14 hour shift im not exactly ready to fight with 5 people.
