Suddenly, my phone stopped connecting to 4G network, and even if it connects to 3G at best, the connection is pretty much slow. Phone calls through Dial-Up are not stable and laggy. I tried putting SIM card in another device and it works just fine. Nothing I've changed before this issue happened. After the issue happened I tried to install new OEM 6.0.1 Singapore from SamMobile & tried custom ROM but the issue remains, please help as I don't have another device and I need a solution ASAP.

Hi guys, my friend bought himself this devise about week ago and everything was fine till he accidenty emptied the battery, since then there is a radio problem in his device.
The problem is that he cant get a network and he has no signal notification.
I'll be more specific: the device is finding a network but can't register on the network. I tried about evrything i knew (find networks manualy, change from 3g to gsm, tried some diffrerent sim cards and even HR) but nothing helps.
If anyone have another idea i'd like to hear.
Thanks.
P.S sorry for my english its not my main language.
Have you tried to re-flash to the HTC ROM and seeing if that might help? How about running the Network Connection Wizard?
Problem with 3g after emptying battery
My phone worked flawlessly until I emptied my battery. Now my 3g connection connects briefly and the just disconnects, it's unusable. I've switched to 2g and it works good, but something happened to my phone after it died because of an empty battery. Could someone please figure out a way to make 3g work again

Hello.
Having problems with my I8190N. About 2-3 days a go it suddenly lost ability to connect into internet. I can switch data connection on or off, it doesnt make any difference. I have tried to reflash various ROMs and it's all the same, no internet. I get the usual signal bars but no H/G/E marks.
It did not happen after flashing, had CM11 on it for days and I could connect Internet just fine. No carrier limitations either, I can make calls out and same SIM in my old phone can go to internet.
Should I flash the stock ROM/bootloader back and RMA it? Or is there something else I can do? (perhaps known issue and solvable on my own)
Phone is fairly new, bought it in August as brand new.
i suppose APN settings are correct?
you can try to flash another baseband to try with it, what is yours current baseband?
basebands you can find here for N version, XXAMJ ist newest and working for me...
I had the same problem a couple of days ago. It turns out that my problem was the simcard, have you tried to put another simcard in your phone and see if it works?
I have this problem, same with two phones and two SIM cards, both phones are ZTE, both problem SIM cards are on Vodafone, both phones have no problem connecting to data via t mobile sim? This leads me to believe that voda data does not work on zte phones, apn details are correct. Does anyone knowa fix?
finally sorted it........... f'd around with a few different apn's and even phoned up talktalk(same as vodafone network) who confirmed I had the right settings which I hadnt!
Found the correct settings on the geeksquad website. seems i didnt need to bother filling out some of the fields and then wham internet connection straight away!
Sent from my ZTE V967S using xda app-developers app
Hi,
I have an HTC One M7 with it's original Vodaphone ROM (UK, vodap102)
Everything was ok but about 2 days ago suddenly it lost it's cellular network.
from time to time it connects but looses it again the moment i try to enable mobile data.
I have tried to reboot, factory reset, tried different SIM cards (from same company) but nothing.
when i go to network operators sometimes it can't find anything but sometimes it finds all the networks around. when i try to connect to my network it tells me it "Your SIM card does not allow a connection to this network"
I had a firmware update as well (sense 6) but after the update was no change.
Is there anything else i can do?
P.S.
The phone is with unlocked bootloader, S-on and is being used in a different country, not in UK. as i said, it worked perfect for about a year in the same cellular network
Please asist, Thanks.
A little update...
If i choose 2G only, it works fine. but only in this mode.
any suggestions what might it be and how to solve it?
Hi at all.
This is my first Post, but i cant get any further with my Problem.
I used to have cm11 on my I9305 (T-Mobile Germany), everything worked fine (more or less).
Last Month from one day to another my Baseband completely disappeared without any obvious reason.
Luckily I had a Backup that worked with unofficial cm12 rom.
After that nearly everything worked.
Now, since 2 Days i got a new Problem. Everywhere where I got 4G, my Mobile Data work. But in Areas where I only got H+, 3G, Edge,
I have to switch my preferred connection to 2G, else my Data wont work. Sometimes for Seconds i see the 3G Logo, light up the Status Bar.
But I got no Connection.
The Strange Thing is, that when I call Someone, during the Call, the H+ Connection seems to work, but after the Call, it disappears.
And my WLAN Connection works only after every reboot (Connects, but no Internet, Also very disappointing)
Things I did yet:
-Flashed various Modems for I9305,
-Flashed different Roms (CM11, Nameless Rom, Resurrection Remix)
-Smashed the d*mn thing against the Wall :angel:
Information from my Phone:
-Baseband Version: I9305XXALK2
-Mobile Network Type: UMTS (it shows that, but no connection)
-Mobile Network State: Disconnected
-IP: Unavailable
Has anyone encountered a similar Issue, or a Solution?
Could it be a Hardware Problem?
EDIT: IMEI is okay. I try and try, but nothing seems to Work...
Hi All,
Disclaimer: Newbie.
During December I updated my N920I via OTA. Since this update my phone constantly has network drop outs, no 3G or 4G. If I force 2G it will sometimes work albeit very slowly.
Steps taken:
Simcard Replacement
Factory Reset
Manual Flash (N920IDVU3BPL2) via Odin
Prior to this update the phone was working fine with build N920IDVU3BPJ3.
I downloaded the N920IDVU3BPJ3 Optus specific image from Sammobile and tried deploying it using Odin however I received the "SYSTEM REV CHECK FAIL DEVICE 1 BINARY 0" error. From what I have read it means that I have a locked bootloader?
I have been advised by Samsung that I am unable to downgrade? (I assume you can if you trip Knox)
Any help would be greatly appreciated! I haven't had a properly working phone since Boxing day
Thanks heaps
4g/LTE not working on N920I
Same here:
LTE was working fine on my N920I out of the box, but suddenly I observed that its only connecting 3G or 2G but not 4G. I thought that it may be custom rom issue.
I have installed Australia fimware through Samsung Kies. But it did not work.
Now I have manually installed Singapore firmware through ODIN
I have cleared internal storage and factory reset the phone
Upon forcing 4G only mode, the phone does not get signals and gets hot
I have tried inserting my sim to S7 and it quickly got connected to 4G, but 3G does not get connected to my phone
I have also contacted my carrier and they say everything is working fine
I have checked APN settings with carrier as well
I dont know what to do. Does this mean that my phone has some modem hardware issue which has broken modem due to overheat or bad code or something.

Not possible since the S7 worked! Sounds like you need a new SIM card that's all.. Or you can try changing the settings again by going to Settings>Mobile Network>Network Mode and see what it's on..

I have changed Network Mode to 2G only, 3G only, 3g/2G (auto connect), LTE/3G/2G (auto connect) modes one by one after your suggestion but phone is only working on 2G and 3G not LTE.
Earlier I was having N920IDVU2BPG3_N920IXSA2BPG3_N920IDVU2BPG3_HOME.tar firmware but now since I have installed the latest N920IDVU3BPL2_N920IXSA3BPL2_N920IDVU3BPL2_HOME.tar so now I cannot go back to N920IDVU2BPG3 anymore and I get error:
sw rev check fail device 3 binary 2 in odin.
Does this has anything to do with firmware or my Modem chip is faulty due to overheat or anything?

Hello,
same thing happened with my 9208 duos...
it happened some 3 weeks ago and only happened after my phone downloaded some updates..
carrier, sim all is good... issue is with phone software... and forcing it on lte only ends up having no signals..
Biggest prob is that it aint allowing to downgrade to another firmware with odin even...
ps. i dont think overheating of modem would restrict us to H & H+... if it was fried i guess there wont be any data at all...
if you are able to find a solution dont forget to let me know...
thanks

Hello, I''''ve a Galaxy Note5 N920I which wasn''''t bought from Saudi Arabia. My phone doesn''''t connect to 4G at all and at best even if it connects to 3G the connection is pretty much slow, even the Dial-Up calls are not stable and _quotlaggy_quot. I''''ve noticed that whenever I change the data connection to 4G network the device gets considerably hot at the power button side. All of this happened suddenly without any prompt about 3 days ago... I''''ve already tried changing the SIM card and testing it on other mobiles and the SIM worked just fine, also tried to change the APN and network settings but nothing worked. I am really concerned about the idea that the device might explode at any moment.
I have the same problem, my device N920I which I didn't buy from Saudi Arabia but I live there. Samsung S.A didn't help me out but rather than that they told me to contact with Samsung's branch in the country I bought the device from.
At the current situation, I have no choice other than waiting the device to explode maybe.
I regret that I didn't choose Apple's iPhone actually, as they would help me out without such irresponsibility.
Anyway, I am waiting for your assistance.
Any updates on this issue its getting worse day by day! Its summer here and i cant even touch my phone its becoming so hot.
