SIM card not found/lost IMEI after replacing digitizer - LG Nitro HD

Hey all,
I told a friend I would replace the digitizer on his AT&T Nitro HD. The replacement went fine, but when I reassembled the phone and powered it up, it had no service and the "No SIM Card" icon is on the notification bar. I took the device back apart and reseated all the connections on the motherboard. Before I put the back housing back on, I put in the SIM card and battery in and powered it up to test real quick. The phone booted and it had service! I reassembled the phone and booted back up and there was nothing again. I have tried reseating connections again but still nothing.
I have been looking through the unbrick guides and I'm considering flashing a factory image to see if that will correct the problem. I'm fairly sure the problem isn't with hardware. Could the SIM card have been corrupted also?

It's possible that something happened to the sim card. Do you have another active sim to try?

Not a full size AT&T card. I only have access to VZW and T-Mobile micro SIM's.

A micro sim will fit inside the sim slot but it has to be positioned cardfully. You could also get a micro sim to full-size adapter.
If you can flash a stock rom try that and see if that fixes the problem.
Damaging the sim shouldn't male the phone lose its imei. Did you look for it by dialing *#06# or under About Phone?

I have everything ready from one of the unbricking guides to start from scratch, but I would want to back everything up first before going that route. I checked the Settings and *#06*# and they both say unknown/blank.

Maybe try updating using the official LG updater using recovery mode. Make sure to set your country and language. The imei should be on the label underneath the battery.

I actually tried that last night. Upgraded to V20c using the LG Update tool in recovery mode. The IMEI still wasn't present. He is just going to take it down to an AT&T Store and see what they can do.

It was a good effort on your part, that's for sure. I hope your friend has some luck with ATT. Is the phone under warranty? I'm asking because you had to replace the digitizer.

No it's not. I was hoping to get it fixed so I wasn't on the hook to replace his phone because something went wrong while I had it apart. I'm hoping they can take care of it with minimum charges or allow him to upgrade early. Thanks for the advice.

No problem. I just hope they are able to help out your friend.
It's strange that something like that would happen because taking it apart is pretty easy. Maybe something happened before you replaced the digitizer.

No SIM????

Okay, so I got my Galaxy Nexus today... went to put my SIM card in, and it refuses to acknowledge it. I thought maybe it was due to a very old SIM card, so I went in to T-Mobile, explained my situation, and they replaced it with a new SIM card free of charge. Problem is... the Nexus still REFUSES to read it. It keeps saying 'No SIM/Emergency Calls Only'. Help please?
Is the phone new or used? And do you have warranty? It could be because of the phone
It's used. It came pre-rooted with AOKP on it... I was thinking this might be the problem? So, I'm in the middle DLing the GNexRootToolkit to return it to complete stock, and see if that helps. Any other thoughts?
are all the pins there? If any of the pins in the SIM slot are bent or broken, it won't read the SIM.
I also find it hilarious that people buy used phones without knowing for sure the SIM slot works (one reason to only buy locally for used devices). I personally will never buy a used phone that is also rooted/unlocked/ROM'd. I don't wanna get some hand-down phone that's been messed with. If they can't be bothered to return it to stock, I won't buy it.
Okay, that seemed to fix it. Thank you for the quick replies!
Can't believe you bought a phone without checking if it worked. Smh. Well, glad it worked out for you.

Galaxy Nexus won't read any SIM

Hi forums,
I recieved my Galaxy Nexus i9250 european GSM/HSPA+ Version today (Just the tether-slave for my N7 and a phone obviously) but now I have the problem that it won't read any SIM i put in it, I've tried 2 Vodafones and 1 T-Mobile (all 3 are working perfectly fine on other Phones) the problem is that it won't know if it has a SIM in it or not, I don't have to enter a password when I boot up or go out of airplane-mode, I can't connect to any networks or change APNs and I can't change the SIM-PIN (no option for that)
What I've tried so far:
I got it with 4.2.2, I've flashed 4.3 several times, did factory-resets, OEM-Lock and unlock, flashed a few different basebands. I also tried to bend the Pins a little bit upwards, they definetly have contact with the SIMs.
I have no idea what else I could do, I have about one year of warranty left over, should I use it or is there a way to fix this issue?
Thanks for your time and help in advance!
Greetings from germany.
The SIM tray is busted. I'd get a refund if I were you.

Indeed it was, 3 whole pins were missing! I just took the pins from an old phone and soldered them on there, now it works but That's only a temporary solution, I ordered a whole new Sim-tray and will give the phone to a friend with proper gear for this kind of stuff (really annoying to try and do it with a big soldering iron...)
Warranty might be screwed now but I'm not sure if I would have gotten a replacement at all, I guess not but anyway, I waited two weeks for this baby and didn't want to send it away again but I don't recommend doing this at all
Thanks for your help!
Oh and BTW I figured out what might have caused that, I used a micro SIM in a mini-SIM-Adapter, not such a good idea since this makes the card much thicker, I think that killed it. Ordered a new Sim as well.

[Q] Sprint SIM Card Not Recognized

Hi everyone,
I am having a little issue. I recently updated to KK and jut didnt like how it preformed. I .toted back to ZV7 to start fresh, this is when I noticed I had a sim card in my statusbar with a little X on it. Then I noticed that I had no LTE. I can't figure out if I did something wrong or what.
I had one of my developer friends walk me through a few things that he had to do on the G Flex, which was toting 5 or more time till that sim card was recognized, well mine still doesnt work. heck I even went into Sprint to have them check it out, and all they did was replace and scan in a new LTE card.
Could me Sim slot be turned off? or could it be fried?
I have had this issue sort of
i have had the lg g2 on sprint for about two months and i occasionally get a similar issue except it just says that there is no sim card inserted however my LTE is completely un hindered. and it would normaly correct its self after a couple reboots. is your device damaged in anyway and how long have you had the device,
It corrected itself over multi reboots. several days worth of reboots. The phone is now ongoing its 3rd week in immaculate condition. and its been babied, so no damage whatsoever.

[Q] Unable to detect sim card

I bought my note 4 on launch day. Ever since then I've had an "unable to detect sim card please restart phone" error. At first it only showed up once every few days, but now it is getting more and more frequent and is happening multiple times a day. After reading starting the phone works fine for a while. I've done everything I can think of (pulling the battery, pulling and re inserting the sim, cleaning the sim), but nothing helps. Anyone else having this issue, or know of a solution? Thank you.

I am having the same issue. Not sure of a fix yet but it is getting more and more frequent which worries me.
Same here. :sadface:
Same here! Anybody contact Samsung or Sprint about it?
Same here!!!
Just got my note 4 from Amazon.com. I had been reading about the lte to 3g call drop issue, and someone posted using there sim the card from the phone they were replacing fix this issue. So I put mine in from my s4 before i even turn it on for the first time. The phone worked, but was unable to connet to the 4g (lte / spark ) network. 3g worked fine. I got the message you all are getting (no sim, restart device....). It would happen like every 10 minutes. Once I put the sim that came with the phone in , all my problems went away. Long story short, you need another sim card.
I just called sprint and they are sending me another SIM card. It happens from time to time, but they did tell me if it continues, I can get it replaced for no charge.

This happened after my sim card swap. It would say "network did not respond in time" then "could not detect sim" then phone would reboot. It did it three different times. Then connection became stable and has not done it again. Not sure if these issues are the same as whats happening here. Just posting my experiences.
I actually bought 2 N910P. I planned on making a little extra money by selling 1 of them, but didn't count on the N910P being so easy to get, so I've held onto the other one for a back up until I found a ROM that I wanted to run on it. Well, I found a awesome ROM & booted up my 2nd N910P & got the message you have all mentioned. I thought it was strange, so I rebooted & got the same message again. After doing this a few times, I thought why not take my SIM card from the 1st N910P & put it in the 2nd N910P. I still got the same message after doing this, so I swapped them back before it messed up my primary SIM card. @Yoshi1221, please keep me/us updated if the new SIM card works for you. Has anybody else got a new SIM card? Also, after installing the 2nd ROM that I was trying out, the fingerprint scanner stopped working. I went back to stock & it still doesn't work, so I made sure that I did a full NANDROID backup on my 2nd N910P in hopes that once I get it working & the fingerprint scanner stops working, I can go back. Anyone else had this trouble?
Edit: I tried to activate my new GN4, but the DEC & HEX numbers were not recoginzed by Sprint.com. So I went into chat & they informed me that it had been turned over to technical support & to contact them again after 24 hours, so we'll see where it goes from there.
Update: Chatted with Sprint & the lady activated the SIM card after giving her the number. Hope this will help out. Just go to Sprint.com & click on the chat button.
Looks like new SIM card is working, but just got it today, seriously had to give up an arm and leg in order for sprint to send me one, but so far it looks like it is working, but just got it today, lol

Cool, glad it work out for you.
Also found out from a supervisor in the U.S that sprint is now selling GSM phones now. If you take out the SIM card and only receive 3G, you have a GSM phone, if you take out the SIM card and have spark/LTE, you have a CDMA phone

I had this problem. Sprint sent me a new sim. Fixed the problem for a few weeks but it has returned. Anyone ever get this figured out?
Sim card not found
I had forgetten about this error. Saw that someone suggested a piece of paper between the sim and case cover. I had this happen with a phone I got off a forum. Sent it back and got a replacement. The paper, no matter how thin or thick may or maynot work, and only for a short time. Changing the sim might not work either. You may just need a new phone. I went through all with a s4. Now my note 4 is doing it. I thought it was my recently deceased (July 4) mother was messing with me. One more errand to add to my list for today.
same here?
help plz

Sg3 not recognizing SIM card even after replacement

So I have a couple of SG3's. I wanted to give my wife my spare but the reason I wasn't using it was due to the dreaded sensitive power button issue.
I removed the power button from the mainboard carefully.
I popped the SIM card/SD card back in and used the the charge cable and the volume down/home button to get it to boot up. Success. It booted fine but no Sim card detected.
I know the SIM card works as it's the same SIM I use in my daily SG3 phone.
I hit up the internet and read some items that said, Factory reset the phone.. Did it.. No change. Put a piece of tape or foam on top of the SIM card to make it fit 'tighter', no change.
I ordered a new SIM/SD card module and replaced it on the mainboard.. No change.
The phone is running Cyanogen 5.1.1 12.1-20150527 Unofficial d2att with Baseband I747MVLLE8 and Kernal 3.4.107 Deathly Rebirth.
Any help would be greatly appreciated.
What is the phone's model number?
Did the phone detect a sim before flashing a custom rom?
The baseband doesn't look familiar to me.

The phone is I747 and yes. I used this phone with this rom fine a few months back till I started having the sensitive power button issue and I purchased a new to me S3. This phone has just sat for about 5 months. I pulled the power button, and inserted my SIM and it booted up fine but with no SIM detected.

I'm starting to think it may be the main board for some reason. I'm tempted to buy a working used phone that is local for $40 but has a smashed up screen and pull the mainboard and pop it in my phone and trying it out. If I try this, is there anything else I need to be concerned about other than it being the same model and having a clean IMEI? I'm not concerned if it's locked because I can unlock it for free.
Just want to be clear. The first s3 (I'll refer to as number 1) was fine and developed a power button issue so you stopped using it. You then got another s3 (I'll refer to as number 2). You put number 1 away for a few months, removed the power button from number 1 and this is why it stopped detecting the SIM card. Is this correct?

Your numbering is correct. However, I am unsure if removing the power button is what caused the SIM card not being detected issue. I'm no engineer but I'm unsure how the two would be connected but it is a possibility.
How did you remove the power button? This is usually done by melting the three solder points on the board with a soldering iron and a solder sucker.
I would not expect the sim reader to be affected by removing the power button.
Does the sim work in phone 2?
Does the micro sd reader work? The sim reader and micro reader connect to the motherboard through a single connection..

Don't cringe, but I followed a youtube video that shows how to 'scrape' the power button off.. I talked to the guys at my local cellphone fixit shop and they confirmed it does work but isn't the way they usually do it. (They use the soldering iron method).
I will test the SD card in Phone 1 and then I will test the phone 1 Sim/SD card module in phone 2 and get back to you. Hopefully tonight.
Thanks for the help

Ok so I just performed the following steps.
Phone 1 booted up and is reading the SD card but still no SIM card detected.
Removed SD/SIM module from phone 2 and replaced it with the original Phone 1 module (the one I thought was defective so I ordered a new one) and SIM card and SD card both work flawlessly.
So I'm starting to believe it may be the mainboard at this point unless there's something else you want me to try,
excuse for butting in , but when you changed to phone #2 didnt you have to go to ur carrier to have them enter phone #2's IMEI? if so that might be why phone #1 no longer recognizes the sim. i.e. , phone #1's IMEI is no longer registered with carrier.
or ...... maybe i have it all wrong.
if so , please disregard all the above.

Curious to know if this is indeed the case although I don't believe so. I didn't have to tell my carrier when I switched from Phone 1 to Phone 2. I just popped in my SIM card from phone 1 to phone 2, and it told me it was locked and I entered in the unlock code and the phone has worked.
ok then. must not be the case.:good:
srry , have no other ideas.
