Hello Experts,
I am using Galaxy S duos(GT S7562). I was checking the Service Mode utility and doing research on 850 3G frequency for Latin Countries . selecting band selection on service mode suddenly , my network has disconnected(Wifi is working though) . Even the Network selection ( APN etc) have been greyed out .
I see the baseband version and IMEI number and network types shows unknown .
any suggestions ?
millions of thanks in advance
Good Morning,
I own a Huawei hnour 3c international version which i bought from a Zong carrier the issue is there is no network mode option in Mobile Networks due to which it only uses 3g when Zong carrier sim is inserted, is there any solution by shich i can get network mode option and is it possible that i get network mode option if i flash a custom rom on my phone? or any other alternate way so that i can use 3g with other carriers than Zong, i already checked APN is not blocked . Hope you'll help me.
Thank You
I screwed up band modes, in Engineering Mode i unchecked band modes for LTE except Band 3 and clicked set and then rebooted phone, now phone does not connects to sim at all and no band is checked at band modes in engineering mode as well. opening it says "Query Current Mode Failed", "Query Supported Mode Failed".
really need help to fix it.
flashed rom but still doesn't work
IMEI numbers gone, how to fix that?
Also, on About Phone > Baseband version is showing "Unknown"
IMEI restore than sim will working
I was have same problem. I restore NavRam or NavDATA from backup was i created from TWRP also u can restorefrom MetaMaui 9.1 Application from pc.
Recently i have flashed my moto g2(XT1068) with resurection remix custom rom and i don't know for some weird reason my phone is not receiving any network. I have cheked my phone's imei number it is there and not wiped during the flashing process. My phone detects the sim perfectly but only problem is that my device shows "no service", when i try to select mobile network manually from sim management, it shows "error while seaeching the network" and when i select automatic select mobile network it shows "registered on network" without taking any second to search. My phone keeps showing "no service" in the network section. I have already tried flashing stock rom but it did't work, now You guys are my last hope. please reply to my problem. Hope you have number of possible solution!!!!
Hi everyone,
First post on XDA after years looking for solutions for my smartphones here.
I was playing a bit with my Archos 50 Diamond (dual-sim, 2015), in order to use it as my main phone, as my current one is slowly dying. I purchased a new touchscreen I replaced myself as the former one was broken, and tried to put my SIM inside. No signal.
I tried a factory reset. Still no signal. SIM was detected, asked for PIN, but no signal. After searching in several forums, I managed to arrive on Radio Info settings. (code through dialer is *#*#46363#*#*, anyway I cannot access any code through the dialer, don't know why, so I arrive there using an app downloaded on Play Store)
As I was playing around, I chose "Choose Radio Band" and selected USA Band. Big mistake. All frequency were gone (GSM, LTE) and the "prefered network" option is stuck on "WCDMA only". Of course, I live in France, we use GSM/LTE frequencies, so no signal.
Moreover, the "Turn Radio on" button doesn't affect the radio cells.
After a few factory resets, I already tried the following :
- erasing modemst1 and modemst2, through fastboot. It resulted only in erasing IMEI, great. I restored IMEI through "IMEI changer.exe" I found on the web. Both IMEIs came back.
- enabling all necessary bands through CDMAtool (or Qualcomm QSPT/QXDM tools, it's the same process, using Android Diagnostic Mode) - All GSM/LTE bands will appear on the smartphone using an app like "Network Signal Guru". After that, I can change "prefered network" in "Radio Info menu", so this is better that stuck on "WCDMA prefered". But the SIM is now undetected, no PIN is asked, so I cannot even verify if signal is back.
- Adb shell su -c "radiooptions [arguments from 0 to 8, 0 resets, 5 turns on)" _ using option 5 will actually turn Radio on, but no effect on if the SIM is detected or not. By the way, it turns radio cell for 1st SIM, but not for 2nd (we can see it in "About Phone, State" in phone settings)
- Tried to edit build.prop in order to see what I can do, but I couldn't see no effects either.
- Tried to flash NON-HLOS.bin, but didn't help either. I couldn't find fsg file inside my factory firmware image zip.
So for now, I know how to enable bands I need with CDMAtools, and turning on/off radio cell through adb shell or Terminal Emulator. However Radio Cell will turn off automatically on every reboot, need to turn on manually everytime I boot.
But SIM is not detected at all. I'm not sure if there would be some signal if SIM was detected, but it would be great if I could figure it at least.
Phone is rooted, STOCK firmware Android 4.4, no existing custom ROM, can boot into CMW if needed.
I've tried a lot of tutorials, I don't even remember which ones I did or not, but I'm pretty sure I couldn't find solutions on XDA or stackexchange at this moment.
If you can help, thanks in advance
Cheers
