Hi,
I recently encountered a very strange issue.
G935W8
My phone started to lose cellular service over the weekend, and now with the SIM card, it says phone is out of service.
If you search for network, it does not work either.
I tried the following:
1. Using a different SIM Card with the same carrier, it won't work.
2. My SIM card works at the other phone.
3. Tried to reflash the whole phone with Odin, and it did not work.
I am suspecting the Baseband is broken, but I tried to flash different Odin firmwares, and non works.
I sent it to a local repair center and they said it could be the root destroys the motherboard which I am a bit skeptical.
Please provide me some advice if possible.

Okay so basically, I bought an S4 from local ads, unlocked it via a service i paid for as the free one on here didn't work (couldn't access service mode).
Entered given code, unlocked fine, was using it for about 1 hour and then it said something along the lines of "sim card removed, mobile data will not be used until valid sim is inserted".
Now it shows that there is no sim inserted even if there is.
I've tried multiple sims, including the original network it was locked to, still no sim stated.
I've tried flashing a lower modem in Odin, i've tried flashing the latest ROM in odin, (all official).
I have now run out of ideas! I phoned samsung support and they didnt do any troubleshooting and said it needs to be booked in for repair, im pretty gutted as i'm without the phone for that... Was just wondering if its a common fault? and any easy way to fix it.
Thanks in advance!
Before you judge me by saying how i'm posting something thats done before, it hasn't, I've searched everywhere no methods work
Please, someone help me I've been at this for 4 days now and maybe just 15 hours of sleep :crying:.
The phone I have right now is the SGH-i337m Galaxy s4 running NC1 with MDJ modem (Kitkat 4.4.2) Does not detect sim, it says "No sim available".
I'm not exactly sure if the phone is from Bell but the phone use to be running fine on my old rogers sim card until I updated to their new ShareTap Sim.
With the ShareTap Sim the phone doesn't detect my sim anymore. So I tried my Share Tap Sim in another unlocked phone (Galaxy note 3) it worked fine.
Then I tried a Virgin mobile sim card on the S4 and it detected it and worked fine also. So then I tried to unlock it by flashing it with many different methods:
1. I tried flashing a older version of Bell 4.2.2 but it bricked my phone ( I already unbricked it back to 4.4.2)
2. I tried flashing the MDJ modem but it doesn't show the hidden menu.
3. I tried flashing ATT modem to try it but that also bricked my phone.
4. I tried to use the AWS tutorial shown here
5. I tried the regionlock away tutorial here in the third method (RegionlockAway doesnt do anything to my phone)
6. I pulled the modem.bin from the TAR file from sammobile of Bell's 4.2.2. But it still doesn't show the hidden menu! It's the MDJ modem but it still doesn't work!
I'm not sure whats wrong with my phone. When I put the Virgin mobile sim card in there it only shows Telus, EXT and Virgin Sim networks available not the whole spectrum which is what is supposed to happen with the 337_aws.qcn file from the AWS tutorial. Then when I flash MDJ modem from bell or the one from this dropbox link: https://www.dropbox.com/s/2m3id2cx4l...37MVLUAMDJ.zip
It still doesn't show my secret menu.
The secret menu I'm trying to access is the *#0011# but if that didn't work I also tried the *#9090# It still doesn't show the secret menu. So what do I do now? Please Help!
Thanks for reading!
Sorry to hear that, but you are in the same situation i was, the phone was probably sim-unlocked by Box Software, like Octopus or Z3X Boxes as i did, the phone won't recognize some sim cards by unknown reasons, there is no fix avaliable for this as i changed imei, tried different NVM from other phone & even replacing sim card reader. i finally sold it & got myself a i337m unlocked via code.
Edit:
forgot to mention, My SIM stopped being recognized when i upgraded it to a newer LTE version
Kind regards.
Have you tried stock NC1 with the included modem? If the device is unlocked, you might have better success with SIM recognition. In my case, my device was not unlocked, so I Odin flashed stock Telus MDJ, then rooted with CF-Auto-Root, unlocked with RegionlockAway (KNOX tripped), and applied the AWS Mod.
Then I flashed stock NC1 with the incl. modem (root gone), and managed to get Rogers LTE and Wind H+ on the Telus device. From there, I OTA updated, and rooted with CF-Auto-Root, flashed TWRP, and worked my way to 5.0.1. Trust me I know how frustrating this can be, but thanks to this forum, there was a solution. Here's what worked for me (link). Good luck.
Hello, the phone on firmware APF2. Menu there are no hotspot. My opeator not a sprint, your phone is connected to another operator. Sim card and not a sprint, and from another operator.
How to make a hotspot to display the menu?
Well, from that message it sounds like your SIM card is not a sprint one. Who is your service provider? If it not sprint I would suggest using the unlocked firmware G935U. If you are with sprint I would try possibly a factory reset or take out the SIM and reinsert it. If it is still not working re-flash the pf2 firmware.
My GSM operator www.orange.md and CDMA (Number prescribed in the phone itself.) www.idknet.com.
I've tried to do is reset to factory Adapting and twice pierced him. Hotspot Menu appears.
You can easily sew G935P firmware from G935U? Problems will not be? Do I get bricks, blocks?
I haven't tried my self yet, but there is a whole thread talking about the unlocked firmware and using it on a print phone. You should take a look.
ok
Galaxy s7 Edge (snapdragon) from sprint.
I SIM card locked randomly while i was recording a video. I tried to flash stock it and did factory resets and nothing worked. I went to sammobile an did the latest rom atm. I have a history of rooting my phone and got bricked a couple of times but nothing I never heard of a brick that blocks your SIM card. Is this a brick problem or is something wrong with my phone? I went to the sprint shop and they said its not the SIM card.
is the phone working normal with exception of not being able to make calls ?
if yes, then it is a software problem in either the modem or csc.
if no, then your phone is bricked and you may need to take to a shop that has a box to fix it.
The phone is working fine. When I first restart my phone, it has service for a minute or two. After that it gives the warning that my SIM card is locked. So I'm not sure if it's a brick or not.
Hi Everyone,
I just bought a brand new s10+ from marketplace. I ran a full imei report and everything is clean & not blacklisted. It was a sprint phone however the provider I use is consumer cellular (uses ATT towers). When I put my sim card in it obviously said invalid sim and request it get unlocked. I wasnt concerned because I was going to convert it to unlocked anyways via odin like I did my note 9. I reflashed it via odin with the u1 firmware. However the same thing is happening it keeps saying invalid sim and the button for mobile operators is not showing. I have a tmobile sim card and if I put that in it works fine. Being though tmobile and sprint are the same thats why it works fine. I also have a ATT sim card, If i put that in I get the same invalid sim message. So it still appears to be locked somehow. Only sprint / t mobile sim works. I thought by reflashing to unlocked it would unlock the phone sim.
Just to be clear the phone is brand new and never was attached to any account.
Any ideas? I dont know what to do here.
Thanks!!
As I understand, phones that are locked to a network are not just software branded... also the phones hardware ID. So flashing a generic firmware is not enough. You need to get the phone unlocked from the phone's original operator
I found out what I had to do. I had to use a remote unlock service to remove the software lock on the phone. Its fine now. Thanks
