I had this phone running with this SIM for a couple of years with LineageOS with no problems. Its a Xiaomi redmi note 4X.
Yesterday I stopped having service. I contacted the phone company and they said its not theirs. The problem is that it says there is no service and when trying to search for networks manually it says "error searching for networks".
I searched and there is a solution for it if it has MIUI which is to enable the radio or something like that, but following the steps I dont have that menu. I tried messing with all the config I could but nothing... Tried moving the SIM to the second slot, nothing. IMEIs are correctly set. Wifi works correctly.
I dont know what to do... If its a internal component broken, which one could be? The motherboard or one of the small ones?
I really need help...

Hey guys,
Yesterday I was playing around with some Launchers. While doing so, I noticed my signal disappeared and my phone couldn't find a signal. This is pretty normal in my room, as I have a bad signal here. But later on I found I never recovered my signal, and when I tried to search for a network I got the error, "Please insert SIM to use Network functions."
So I was like, "crap I broke my phone!" It's been a whole day and I still can't get a signal -- or rather my phone still can't detect the sim. I tried using the sim in another phone (Samsung I780) and it worked perfectly. I then tried another SIM in the Tab and it couldn't find it either. So I conclude the issue is with the Tab.
Now the question is: is it a hardware problem or a software problem?
I tried a Factory Reset but no dice, same problem.
I'm on stock ICS (Austria ROM) with Root, flashed via Odin, added Google Now with the fix here in this forum. It's a P6200 16GB with 3G of course.
Could this be a software problem? I doubt it's hardware as the Tab is pretty new, only about 6 months, and I don't change SIMs at all. There's no chance that the sim slot got worn, but you never know.
I'm thinking it's the fooling around I did with the ROMs. In particular it might have been Go Launcher EX wtih all those stupid plugins like the one that lets you turn off system processes. I uninstalled all the Launchers I tried but somewhere in the middle of doing so the signal disappeared and this is when I assume some kind of driver for the sim slot got nixed.
Another thing I noticed is that my PC or my laptop can't detect the phone anymore when I plug it in. This only happened today as well after playing with the launchers. So I'm thinking it's not just the sim slot.
I'm going to try a reflash of my ROM again via Odin, but while I'm downloading a ROM I'd like to get your opinions on the matter, is it really a software issue or is the hardware broken?
Man, when it rains, it pours. Had a bevy of issues this week, including both of my internet connections going down explicitly, so I have no broadband. I am typing via my phone's sim, which I had to pop in to a USB dongle.
Anyhow, here's what I've gathered:
My phone's baseband is corrupted. I have a "Baseband Version: Unknown" thing going on in my Tablet. That's probably the source of my woes.
But my other problem is that I can't connect via USB to my PC no matter what I do. Does the baseband also affect that? I can't even update via Odin. I'm trying to figure out a way to update this either by WiFi or by MicroSD. Is there a modem.bin file that we can flash via CWM or 3e or some other updater in Power + VolUp mode?
If I can't find one, I'll try going to my aunt's house to use her internet connection via WiFi, might be able to solve everything through KIES.
As the the title suggests,
My dad's boss purchased this phone and while it works with any sim you place in it, upon turning the phone on, it basically summarises the following,
You have inserted a USIM that is not part of LG U+, and as such will be data locked.
(not word for word quote)
Now I take this to mean that the phone was carrier locked to Koreas LG U+, but the phone works here, and phone calls, and 3g speeds, but no 4G/LTE.
The current firmware version on it is 4.4.2 with I believe G900LKLU1AND3_G900LLUC1AND3_LUC
Now I've tried many different things to try and fix this;
I've read that 4.3+ version is bootlocked, (not exactly sure what this changes)'
I've tried flashing an Australian SM-G900I firmware (thinking the bands will be fixed, as its a software not hardware issue as far as I can tell)
Upon trying this, Odin throws a failed error, the download mode on the phone freezes, I can reboot it, and it's all good and dandy.
I then looked around and found that its possible to put in a SIM unlock code, however I query how that would work as the sim already works, just not LTE/4G
I tried Chainfires Region Unlocker (yes I know it said only tested on Note 3), which said succeeded, but actually did not enable 4G.
And I also saw a rumour that, if you place a phone call for 5+ minutes it will unlock said phone restrictions. In the phone logs it does show a phone call occurred previously before this phone was purchased, not sure if it was 5 minutes, but this may have been the case.
I'm stumped as to what can be done to flash this phone (or whatever can be done) in order to force it to allow the LTE/4G Networks,
Just to re-cap for the tl;dr,
4G/LTE not connecting as the phone mentions it restricts it due to being a NON-LG U+ SIM upon turning the phone on.
Please help ?

Hi
I also have g900L and had issue with LTE at the beginning But I resolved the issue by the following;
Please dial 319712358 and they will show you a box where you need to enter password then enter 0821.
This will lead you to the hidden menu page where you can find network mode where you can switch it to 4g mode.

I will pass this info on to the guy that owns this phone (my dad's boss) and hopefully all good,
Thanks man ,
Will post back here once I find out if it works on his phone.
Hi, just wanted to let people know I've had this same issue. Bought a G900L online and the network would connect to Optus' 4G/LTE for a few minutes at start up then will automatically go back to 3g. The solution above seems to have allowed my phone to lock to the 4g network.
Thanks
Hi! I'm having some mayor problems with my OnePlus One.
For some time I have had problems getting calls and sms when using 4G but it seemed to be a problem with my carrier but 2 weeks ago I dropped my phone and the screen broke so I bought a new screen and replaced it. After that the connection to my carrier dropped randomly and now after trying to fix it in different ways I can't get any connection at all with any carrier !
What I have tried so far:
Factory reset
Reinstalled CM
Put paper under the sim for tighter fit
Turned the radio off and on and restart phone
Change pin code
Replace sim-card
Tried different carriers on my phone (my simcard worked on other phones so it is the OPO that is the problem)
Total restore by fastboot-flashing
Installed OxigenOS 2
Tried all modems from the modem collection on CM and Oxigen.
Retyped the APN by hand
Opened the phone again and checked that all cables are connected well
Tried manualy connect to my carrier under Network Operators
For a short time of maximum 10 seconds I got a 4G connection twice in now 3 days of trying but then it stops working again. It feels like a hardware problem BUT I can see a lot of different carriers under Network Operators but when trying to connect it loads for ever and then says "Can't register to your carrier". I called my carrier and thay said nothing was wrong from their end and when I tried on other phones it worked flawlessly.
I'm really out of ideas now and I don't know where to go from here. I really hope someone of you knows that might be the problem!
Thank you so much!
If imei present you can try mobile phone exchange offer on flip kart like online stores. When this happened to my phone I did it , very easy.
Sometimes opo dont search available network or wont register on any network.
Sulution: go to access point and reset it to default first then go to network and try to search for network n if ur able to search then try ro register manually and if it does not work then go to dialer and dial *#*#4636#*#* then click phone info and select the lte/gsm ato prl mode and then click turn radio off and again tuen it onn then smsc refresh and update ( i dnt remember it correctly) if that dnt help then ur network antena is damaged
My Moto G XT1045 was running perfectly fine with Cyanogen Mod 13 for months. A few months ago, for seemingly no particular reason, data, SMS and phone service stopped working completely. I tried a bunch of things to fix it, including a complete wipe, but nothing worked. Eventually what solved it was running the battery down to nothing, recharging it, and rebooting it.
Now I have the same problem, and the battery-killing trick hasn't worked.
When I open "Phone info" by dialing *#*#4636#*#* it reports "GSM service: Radio off."
Pressing "TURN ON RADIO" does nothing.
When I choose "View service Dialling Numbers" from that page, I get a list of customer support numbers for my provider, so I know that at least the SIM is working to some degree.
Another sign that the SIM card is fine is that the list of Access Point Names automatically loaded from the SIM card is correct.
In Mobile Networks->Network Operators, pressing "Search for networks" yields the message "Error while searching for networks."
Here's a list of what else I've tried:
Removed/re-added my Access Point Name
Switched to and from other Access Point Names
Wiped Cache/Dalvik with TWRP
Wiped everything, including data
Installed stock android ROM (lollipop)
Flashed Lollipop Radio Firmware from this thread
Allowed the battery to die and recharged a few times
Booted into safe mode
Any other ways I can diagnose or potentially solve this problem?
I recommend contacting via pm or by posting in that radio forum asking for losts101's help.

Did you manage to solve this eventually? I am dealing with the same issue on my Moto G XT1039.

Unfortunately no, I eventually gave up and got a new phone. It was getting about time for me to buy a new phone anyway, I ended up getting an Honor 5X (I love it!)
Hi,
I just got my pixel 4a and I it's not working.
It detects the sim, I can see the name of the carrier, but no service.
I tried factory reset, 2 different carrier sims, both working on different phones, both were detected by the pixel 4a, as stated above.
I can not switch to manual selecting the operator and when I try to call a number it says to turn off airplane mode, but it is not even on.
I did the *#*# bla bla and it say radio of and I don't have an option to switch on.
Bt, wifi, nfc are working.
I was bought from gstore germany and i'm using is in Romania.
On google help forums I saw many similar situations but nu solution.
Hope to find one here!
Hi, Same here.
couldn't find any solution for this.
Not sure if I have the same problem but I have issues staying connected while use google Fi. The connection seems to be intermittent.
Also, my phone crashes every time I manually switch carriers and open my messaging app.
