Could anyone help me and show where the wifi chip is?
This is picture of this motherboard:
OK, so I have the second question. What is wrong? My phone doesn't detect SIM card and WI-Fi doesn't work. Phone is trying to start, but I get an activation screen. I may choose WiFi communication or SIM card. None of them work.

Hi there,
I'm on vaca for one month in Africa and I am trying to use my sim card but I have this message :" Your SIM card does not allow a connection to this network "
I tried two different sim cards but I still have the same issue.
Note that the phone was working perfectly yesterday with my Tmobile Sim Card.
It's an international One X so I don't think that I need to unlock it.
Do you guys have any solutions?
Thank you
it sounds like something tmobile end has changed on your account, if possible i'd call them to see if they can help get it working again
other thing to check is the roaming settings, check its enabled etc
Thanks for the reply.
I'm not using that Tmobile sim card anymore. But an Orange one.
Should I factory reset it and see if it'll work?
Thanks
i had this happen on mine, ive got tmobile sim, it went to tmobile orange signal, i tried to manually switch it back to tmobile (better signal coverage) and it said the same thing.
A reboot didnt fix it so i went into settings, storage, make more storage and then cleared all temporary data for all apps.
this seems to temp fix the issue and allows me to reconnect to my peferred network it still happens every now and then so it could be a software gitch with the hox
Just tried it. Didn't work
I will restore it and see how it goes
Even with the New Rom, Superwipe I still have the same issue ?
I have this I317m locked to bell. I am trying to use it on virgin mobile canada. From what I've read, I shouldn't have to unlock it to use it on virgin. Anyway, when I insert my virgin sim card, sometimes it'll say unregistered sim and other times it'll just tell me emergency call only. When I look under status, it knows my phone number and it knows that there is a sim card inserted, but it won't let me connect to anything. It's completely stock and on 4.4.2. It never asks to enter an unlock code when booted up and no combination of any symbols and numbers that I have found on the web results in anything happening through the dialer. I have an unlock code for it and I cannot input it anywhere. I am starting to think that I have a hardware issue of some kind and hope that it can be confirmed with help from you guys. Any advice would be greatly appreciated.
So it can pick up virgin under available networks, it just can't register on anything. This time, when I turned it on, it read virgin for a split second on the lock screen then switched to unregistered sim and then to just emergency calls only. It has bars showing up, I just can't connect to anything. strange.
Well, I have it all apart now and figured for the $7.69 it costs for a new sim reader and micro sd reader, I'll give it a shot.I kinda have a feeling that it not the issue though. I'm kinda leaning toward the nand being fried or something like that.
Have you checked that the IMEI was clean?
The imei comes up under about phone and matches the sticker. What else is there to check? It also shows up doing the #*06# trick.
Aha! Checked IMEI. Not clean. Will fix properly now. Thanks.
Which normally means you're in possession of a lost, unpaid or stolen device...
Hey Guys
Got a Nexus 5X I need to fix for someone and I'm a bit stuck. Supposedly it happened out of the blue for the user without anything like being dropped etc. The phone when a SIM card in inserted never registers onto the network, it gets the empty outline signal symbol without any bars and shows "No Signal"/"Emergency calls only"
The SIM gets detected when I unplug/replug it in. I have tried multiple working SIMs as well without luck. The phone also does show the IMEI number and also the Baseband version so I don't think it's a problem with the radio software wise.
What I have tried is the following;
Flashed STOCK ROM over itself.
Flashed CUSTOM ROM on the phone
Flashed only the radio img over itself
Reflowed the board thinking the SoC might be at fault
What I don't know is at this point is it a software issue or hardware issue? There should be nothing stopping it from getting a signal as the phone isn't showing no baseband or no IMEI number. It just stats unknown network and not registered for network when you go into the About > SIM status
Anyone know a way of sorting this out? :fingers-crossed:
I also have the same problem. My 5X can detect the sim card but doesn't show any network. Hope someone can give a solution to this problem.
I am having a very similar (or identical problem). My phone detects the SIM card but shows the 'service state' as "Out of Service" and the 'mobile network state' as "Disconnected" Under the network settings it appears that the phone recognizes my mobile carrier and has the correct APN settings best I can tell. In my case I think its likely that I screwed something up when wiping the phone and installing a custom ROM. I think I may have somehow screwed up the EFS partition. I dont know for sure, but ive read that this can be the source of mobile connectivity issues.
Replaced Mainboard - "Not registered on network", Network bars & IMEI present
Hello, my Note2 phone had a call problem (would dial but no audio/voice) so I bought a cheap replacement board (ie no guarantee), seller said it needed firmware fix.
Swapped over and on boot saw a Kies prompt to reset firmware load - so I flashed TWRP and a Lineage rom in Odin and brought it back to life.
However, Network strength was zero and no calls possible. After many tweaks, swapping SIM cards, I reflashed stock 4.4.2 rom. Now I have good signal strength in the taskbar, my board IMEI is present but the dialler returns "not registered on network". Phone status shows signal strength, correct network but Service State - out of service and Mobile network state - Disconnected. Just flashed MODEM.tar.md5 but no change there.
Could this be a hardware issue? ie why the board was cheap? If so, is it the SIM reader (ie replaceable) or other component? Happy to cannibalise parts from 2 boards to make one working. Or maybe another soft issue I am not aware of?
thx
The sim card and SD card reader are contained in the same part and is swappable.
Does the phone detect a sim card? Is it possible the imei has been blacklisted?

Tried swapping that part, no joy; when I remove SIM and reboot I get the no sim card message. Yes a blacklist is possible who knows.
Considering throwing in the towel now, my main Note 2 makes calls, but has no NFC and no audio via jack; my 2nd cannot make/receive calls and now the 'replacement' board is possibly toast. Might just part out the lot and get a new phone now
You can check the imei for blacklisting here: https://swappa.com/esn
Hello everybody i have Samsung Galaxy s21 FE 5G "SM-G990B/DS" Snapdragon 888.
I bought the phone second hand knowing it is problematic,
The problem is that when a sim card is inserted the phone asks for the pin code then once the pin is entered it knows if the pin is correct or incorrect, i enter the correct pin but then nothing happens. In the status bar there is that *no sim inserted* symbol. Once i connect to a wifi network and turn wireless calling feature on, calling and sms function of the phone starts working with inserted sim card. Long story short without wifi connection sim doesn't work at all. I hope i've described my problem clearly.
i can provide every bit of information about the phone.
Thanks in advance to anyone who helps.
Edit: I have tried re-flashing a new firmware via odin.
Perhaps the calls work over WiFi, because the SIM provider allows you to make calls over WiFi through the google carrier service.
So, you probably have a faulty RIL as the SIM card was read correctly.
What possible way i can fix it? I can't find many sources about s21 fe since its a relatively new device and not very popular around devs.
