Good morning, my phone card suddenly stopped working on the network a few months ago. I believe I may have disabled some things here and there the night prior, I can't remember. I was moving from Germany to the U.S. the next day, so I had alot on my mind. This is the European variant (SM-G935F). I have tried 3 different SIM cards, one from German T-Mobile and two from Verizon in the U.S. to no avail. I have posted screenshots showing what it says I have for signal. Every once in a while it pops up with a message saying SIM card refreshing or something like that. I have tried putting a piece of paper by the SIM card because possibly the contacts were lose and I also factory reset my phone but nothing works. To send it back to Germany to have them fix it is very expensive and also I don't want to try and interpret everything. I have done that for the last 3 years and would probably end up signing a lease for a car with my limited German language skills. Any thoughts? The phone is perfect other than this issue and I am about to put it on Ebay if I can't get it squared away.
Thanks in advance for any thoughts!

did you try to root it and put the bootloader and firmware of t mobile or verizon?
I haven't tried that because I wanted to keep it unroofed if I needed to sell it on eBay. I might try that as a last step before I sell it though
try to flash your phone with smartswitch or odin with original rom if you are skilled, reset seems cannot recover all your settings.

Hi
Ok so my phone was working fine on a custom ROM when suddenly yesterday an exclamation appeared next to the phone signal and stopped from receiving/making calls and texts. I thought it had just crashed but after soft and hard resets and changing to a few others sims I just can't get my phone signal back.
Really strange as everything was working fine. I now have trouble flashing custom ROMs and am struggling to run a stock ROM because I'm on a mac.
It's driving me crazy as my phone is now useless.
Any ideas guys?
thanks
Quick update
I've managed to get the Leo Lite ROM running and everything is good except that damn exclamation mark next to the phone to phone, which means I can't get the phone working.
Anyone know know why this is???
Have you tried the sim in a different phone?
could just be a simple issue
And I know it a simple thing............but have you got flight mode on?

Thanks for the reply John.
Yeah currently having to use the sim in an ancient motorola and it works fine, tested with calls and texts. Also tried turning on and off flight mode but still that bloody exclamation mark stays.
That sounds like its been blocked. Theres a network there it just isn't letting it connect. Did you buy it second hand? or off ebay?

Hey Sam
Do you know what, I did buy it second hand, from a reputable store in town.
However this raises more questions than answers;
1. Why would it be blocked after several weeks of normal use.
2. Doesn't some sort of message need to be displayed stating the handset has been blocked.
Does anyone know if this is what happens when a HTC HD2 is blocked? i.e. the exclamation being shown all the time.
I presume a handset is blocked for security measures like theft. I will take it back to the shop tomorrow, they will have all the details of the person who sold it to them.
However is there no way this can happen from flashing custom ROMs? Even though that doesn't really make sense cause I had a ROM that was working fine and this happened when I was out and about.
It could be a bad rom, but it certainly wouldn't be in every rom.
I think id try going back to the stock rom, radio and spl (i.e an sd card flash, do you now if it has a provider locked rom?) and see if it is still there. If it still won't work, then it's definately either hardware or network.
The reason it could have taken weeks is, , seller trades in phone for cash, waits a little while, thinks 'i know'..., reports the phone lost/stolen to claim on insurance, insurance won't pay out without the imei being blocked.

Well I've tried flashing at least 6 custom ROMs, all show the exclamation mark.
The phone was sold to me as being unlocked to all networks, however I never tried with anything other than a o2 sim.
Now going back to the original ROM has its own problems. First off i'm quite new at this so sorry for sounding silly. How on earth do i go about finding out what the original stock rom, radio and spl is?
When I have these I can't easily go back as I don't have a pc, using a mac. I would have to use the sd card way but I can't find an official signed .nbh file.
I have a brand new T-Mo US HD2 with similar issue (out of the box). It's like the radio will not initialize. Did hard resets, tried to force it finding a carrier, etc, and it just will not turn on the radio.
I did find out that there is a likely issue with my SIM slot. If I attempt to remove my SIM card (which works fine in other phones) it is almost unremoveable and feels jammed in. However, once removed, I get connectivity via wifi and touch response is great.
If I insert a SIM card, it takes a LOT of pressure to reinsert it (yes, inserting it in the correct orientation), and the phone cannot connect turn on the phone's radio. Also, I get random phone.exe and credential.exe error message (plus the phone becomes very slow.
Don't know if you have any of these other symptoms, but the lack of connectivity sounds similar.
Supposed to get a replacement HD2 today, and we'll see.
I had the same problem too. I got unlocked code from tmoile and everything working fine for a month. It was working great after upgrade the latest rom 3.14 from tmobile download site (i got the message from them to upgrade), until i went out off country last month then the phone could not turn the phone's radio on. It kept at airplane mode. I been try to flash back and forth all the tmobile .50 stock rom and still having the problem.
Does any one know the issue to fix it? TIA
Looks like a hardware fault. You need to open case and check bottom two brass hinges are in working order and correctly hinged to make contact with antenna which is on the rear case at the bottom.
Follow the guide of opening s HD2 on YouTube there is a factory guide to dismantling the HD2.

Thanks for reply xlr8me. I just check the two brass hinges at the right side of usb connector. It looks fine to me. The other thing i didn't mention on the above post I was flash the dft_leo_nand android after tried all the stock rom from tmobile and the android said "no sim card", i also checked and cleaned the sim slot. Do you think any thing else to cause that problem?
One more thing without the sim or sd card the about phone show up all info of phone: imei, serial..... But with sim card in it just blank when i read the about phone hardware info. Thanks again
Did you try simcard from another carrier?

Yes I did tried the sim from the carrier of the asia country i was traveling to last month, that why i call tmobile to get the unlock code before i go. When i was there and inserted their carrier's sim and it won't work, even when i get back to U.S. I been tried either tmobile or at&t sim too. The phone radio won't turn on. The rest is working ok except those above error messages "A problem has occurred with device.exe" and "Credential.exe".
Do you think i can reflash with WWE rom .50 radio instead of tmobile's official rom?
Thanks
htcphonelover,
You will have to reset the phone back to default rom from htc website. You may also need to reformat sd card but the radio should still work regardless of whether the sd card is in or out.
My only concluding thoughts are that if the above fails to work then try a different sim card and still no good then probably something with the motherboard on HD2.
Good luck and update us with any new info..
Dear All,
I write to inform you that i finally solved my GT-I9300 'Not Registered on Network' problem. I decided to make this official announcement so as to assure others, most especially those who have tried almost all the tricks and steps found on this and other forum on the subject that all hope is not lost.
May be if i shed more lights on the problem which i encountered, and i suppose many other people, you will understand me very well. First, i did the upgrade through Samsung Kies and after the phone rebooted, it lost link to network. I called Samsung and chatted online with the Customer Service, i was asked to send the phone to South Africa where i bought it. I called South Africa and also chatted but they could not understand let alone solve the problem. I headed to XDA and other forum to find solution, I tried all versions of ARIZA Patch, none work. I tried all modified ROM, yet no solution. At one point, the problem became complex. The phone moved from not registering on network to 'Factory Mode'. I followed many other steps, but could not get past restoring it back to User mode. I gave up after a month and bought another phone.
My son shocked me last Friday when he said that it will be his first time of seeing me accepting that some problems cannot be solved. I mused over it and told myself that i will rather destroyed the phone totally than giving him the impression that i cannot solve the problem.
I got out my two computers - Mac and PC and reformatted them all. Installed ODIN and downloaded a 4.3 Stock ROM. I then began searching everywhere for any clue as to what went wrong with the phone. My research is simple; the PHONE could not register simply because the IMEI and Serial Number were wrong. My IMEI and S/N moved from 0000 to unknown. After reinstalling through KIES, it came back from unknown to another wrong numbers.
I finally decided to go inside the phone by activating everything on ODIN and see if i can get the wrong EFS on the phone wiped away and left empty. I repartitioned, wipe EFS, etc. and the only thing the phone did was to move from unknown to another incorrect IMEI and Serial.
Finally, i read on a post that the problem is simply software, so i began searching if it is possible to repartitioned the phone completely and turn it into a toy. I recalled that about ten years ago, i successfully installed Nokia OS on Blackberry through a poorly concerted code designed by a friend. In so far i still have the code, I thought that i could do same with my GT-I9300. It won't work, sadly. But in the process of doing so, i realized that using SRS, i can do so comfortably. With this 20 USD software, i gained control of the internal organs of my phone and started out by wiping out the EFS first and with my EFS Backup, i re-wrote it back on the phone. That done, i expected the phone to work, but sadly it refused to register on network.
Not ready to give up, i went further to see what other options are available to me. I realized that i can actually re-wrote my IMEI and Serial number back to the phone. I tried it and after about an hour and almost three attempt, T-MOBILE surfaced on my phone and the GT-I9300 came back to life.
Altogether, i spent two unbroken days reading and reading and applying one step after another, one procedure after another till i finally got the phone back.
SRS can not only do this, but can take back your contract and locked phone from those shylock and give you your phone. It go inside your phone and show you all the codes that locked you to a particular network, etc. It can remove those useless codes that make your phone patented to a particular country and give you an international version. It can also turn your international version to a local one, if you so desire.
I do not know who designed this software, i however testify to its immense ability to safe you from Samsung's irresponsibility.
I am open to helping others and answering questions on GT-I9300.
I have since been enjoying my phone.
what's the short version of the story?

Going by the last lines, it seems this is the tl;dr version
"SRS can not only do this, but can take back your contract and locked phone from those shylock and give you your phone.

Hi! As i understood i need to get SRS and after?
where is the SRS software ? can you post a link ?
Alright so this problem arrives roughly a week ago. I was hoping it'd be gone by now, but nope. Worse than ever.
For reference. I have a Samsung Galaxy S4 i9505. Unlocked LTE international version.
Roughly 2 months ago I rooted and flashed the Echoe a kitkat rom v18. I also have Philz recovery flashed....
My sim card keeps disconnecting while I'm not even using my phone. It doesn't even have to be moving. It just happens. I'll get a message from my phone saying that the sim card has disconnected and to restart to fix the problem..... This rarely works, as when I reboot, I get the error of no sim card.... its really started to get on my nerves. I doubt it's the sim card, as there's never been any problems with it. I will take it into my carrier today and have it swapped out for a new one.
I've seen this problem happen to other people on these threads,yet no answer has arrived. I've reset tp factory etc blah blah blah. I've even uninstalled the last 30 new apps I've installed, and the problem has yet to sort itself. I've tried taping the sim card, putting paper on the top and reinserting. Everything. It hasn't had any major drops for about 4 months so I doubt that is the issue. Only time it's dropped is when I drop it onto my bed....
Has anyone else had this problem? Have a fix? I can't stick it back under my warranty as I've flashed the recovery and rom... voids it does it not?
Any help would be appreciated. Thanks.
I suppose it could depend on modem vs wrong RIL, but unsure. I had such behavior on my old S2, but fixed it with proper modem/RIL combo. Have you checked your logs in data/logs? How many of anomalous logs you have there?
Tried popping in another Sim card, just to exclude yours?
This happened to me. I was using a cut up full size card, replacing it with a micro sim solved it. I replaced the sim tray anyway just in case it was that. It was 5 min job and the parts like a fiver
Sent from my GT-I9500
So I've replaced the microsim with another microsim (both were originally microsims). .. unresolved. Nothing has happened for the past couple of days until it happened yesterday... now nonstop again. I know it's not the sim because it happened even after I replaced it. It just had a couple of quiet moments. Now I suppose my next try is for replacing the sim tray myself. Fingers crossed. Also. No, I wouldn't know a clue on how to even get my logs. Haven't even thought of it. I'll do that when I next get the problem and am forced to reboot. Thank you.
Okay so I've found something possibly helpful. I've only just noticed that this usually happens when my battery hits 100%. I've removed all apps that tell me my battery info..... I hope that was the cause. I'll update tomorrow.
I occasional get the error about the SIM card being removed and need to reboot. Sometimes a reboot takes care of it and other times I have to take the SIM out and clean it. Then it works for a couple weeks.
Anyone have experience with getting another SIM from sprint? Do they charge for it? Do you need to get one from a retail store or can you activate one you buy online?
I have a custom ROM so is that going to lead to problems?(which is why I wanted to avoid going to a location) Will they care about the ROM in store? If buy a replacement SIM does it need OTA activation so I need a S4 sprint ROM?

I have the same issue with mine. It started off occasionally happening then finally quit altogether. I'm rooted on stock rom, they didn't seem to notice but told me I'd have to deal with Samsung about it since it's still covered under manufacturer warranty. While at the store they did insert a new sim card to test if mine was bad or not, but unfortunately that wasn't the case. Here they would charge $10 for a new sim. Now I've been reading mixed reviews on whether Samsung will repair a manufacturer defect on a rooted device. I suppose it depends on the tech you get repairing it.
edit:
as far as the activation of the sim card I don't believe that's the case. I removed my sim card and put it in my girlfriends same model s4 and the lte functioned fine. ie. my sim is fine but the card slot itself is defective
I recently switched carriers to Tmobile and couldn't be happier, they also paid the remaining balance on both my v20's
I requested for the phones to be unlocked which they did.
it of course isn't a phone I want to use as my Daily since I got the V30+ but just for the hell of having a backup
I tried my tmo sim card and it worked I just had to set apns.
Last night I decided to reset the phone cause I hate that sprint bootscreen and also wanted it to be fresh.
I tried putting the Tmo sim card again and now it won't even recognize the sim is in..
So anyone with more experience would or could point me to make it work again ??
I would really appreciate any feedback
thanks!!
No one??
Did you just do a standard factory reset?

Yes!
Settings/backupand restore/factory reset..
And I also cleared the attached Data profile from Sprint with a ##code
Does the t mobile SIM card you're trying to use work in any other device? Ensure that SIM isn't just worn out from you taking it out and inserting it into phones by trying it in another phone. Also confirm the phone sees the Sprint SIM when that one is in. Pay attention to how both SIMs sit in the phone to see if you can see one of them sitting slightly further into the phone or something like that. I'm not sure how you expected your boot to not have a Sprint logo on startup if you did a factory reset though because as far as I know that's just part of the stock OS bootup, even if the phone is running a different carrier.

THIS is the stupid world of Sprint. This is what exactly happened to two LG XPowers I had with Sprint. My GSM SIMs worked great with the XPowers until I reset the device to factory settings or that the device went through a security update. You unfortunately have to get Sprint involved with the unlocking process from their end. And getting Sprint to do something? Good luck with that.
Had I not been getting unlimited free service from Sprint I would have left it some time ago and it's not for their phone or data service, but unlocking devices that is a pain in the ass!

Yes The boot logo goes away when you reset the phone..
When it activates then u get the sprint logo.
The sim card I used work just fine on another phone, I actually thought the same thing you mentioned but nothing.
And yes indeed the sprint sim card reads just fine just no service.
Thanks for your willingness and suggestions though
