No SIM card inserted after unroot and upgrade - G3 Q&A, Help & Troubleshooting

As above really. Not really sure if it's a hardware or a software error here. I've read that the sim card readers can be a little fragile but there was no fuss during the removal so I would be surprised if that was the issue. What I'm wondering is if I've missed something when un-rooting my phone.
I was using a custom ROM, all working fine, but I've got a new phone so I decided to unroot my old one to sell on. I flashed my original firmware using the LG Flash Tool. Firmware file is "UK Vodafone 16G D85510A_00.kdz". It all went great as far as I could tell and I started upgrading. The final upgrade was the install of Marshmallow 6.0.
In order to find out if my phone was locked or not I put my Wife's SIM in. Rather than coming up and asking for an unlock code it simply stated that there was no SIM inserted. I thought that was potentially down to the wrong SIM being in but when I tried mine I was met with the same error.
Have I missed something? Did I need to change the baseband or something during the process?
Any help would be greatly appreciated.
Thanks

I've had kinda same problem since a couple of weeks ago...eventually SIM card gets read for a short while and get back to that No SIM card inserted state.
It has happened with any ROM as well as OG FW flashed through LG tool.
I haven't tried another SIM on my G3 but my SIM does work on other cell phones.

My phone has big problem - "No SIM Card"

Hi,
I had an OTA firmware update about a week ago and all seemed fine. Then a couple of days ago, I started to lose reception... and was unable to make/recieve calls. Initially I thought it was a network issue, then I discovered my work phone (also on Orange) had perfectly good reception. I decided to change network settings (GSM-WCDMA) and no luck. Then I thought I will change SIM cards, and now I get "No SIM card in phone". The original sim card works fine in my work phone, but no SIM card works in my HTC Desire!
Im pretty certain it has something with that OTA firmware upgrade. Also, when switching the phone on it constantly asks me to reset the time.
Any ideas what I can do? The phone is unbranded from CPW.
Have you tried a hard-reset? I'm not sure of the exact procedure, but I'd try that first, or maybe reflash the de-branded ROM to it??
I know the Orange handsets that had been de-branded SIM-Locked the phone after being flashed OTA (search the forums and you'll see) and to get past this you needed to get an unlock code from htccodes (or another)...
Hope you get it working matey...
Orange and T-Mobile have just recently made a merger so all orange and T-Mobile phones are having issues with reception, as for your issues have you got a stock orange desire or are you using debranded desire? If your stock try rerooting using a goldcard and see if this helps any

[Problem] Sim card issue in another country.

Hello folks,
I asked that question a while ago in VomerGuides thread, however the problem wasn't resolved.
The thing is that when I got my sim card and phone from Vodafone (in the Netherlands), whenever I went abroad the sim card was working properly. Then I unlocked my bootloader, s-offed, rooted, achieved super CID and installed custom recovery. After this point whenever I go abroad, and I try to join a network within the particular country the phone says that the sim card doesn't support the selected network.
I talked with vodafone, they said everything is fine with them. They also gave me new simcard in case there was a problem with the old one - nothing has changed. I still have the problem...
Any ideas whether the problem is actually caused by all the manipulations I did, or there is something else?

[SOLVED][Q] IMEI and Baseband unknown. I don't have a backup.

[SOLVED] I put my phone in airplane mode and my IMEI/Baseband came back, cheking the service menu I went to *#2263# and saw that "LTE Preference" was enabled. I clicked on Automatic and problem fixed. Probably a ROM bug? Who knows.
Hello there. I've been a reader of the XDA forums for some time but I never had any reason to create an account to post on the forums.
A few weeks ago I got a SGH-M919 as a gift, the phone only had a few months of use and I took it with me, everything worked fine except for the fact that I couldn't get 3G/4G (Not even EDGE), I was only able to connect to the GPRS network and I couldn't change the carrier (It always gave errors like "Unable to connect. Try later" and such). Although the phone is (apparently) quadband (I don't live in the US), it just didn't work but I lived with it.
Yesterday my phone was low on battery and I turned it off, a few hours later I turned it back on and it couldn't connect to the network, I went to the network options and once I pressed the screen to enter the Mobile Network options, I got an alert saying that I must have a SIM to access those option. At first I thought that the SIM got damaged somehow (This isn't the case since it works perfectly fine in another phone) but after a few minutes looking around, I checked the IMEI and instead of the usual number, I got a null/null message. My first reaction was to google what exactly happened and the answer I received was that the Baseband (Which is also Unknown) and IMEI are stored in a folder called EFS and that it got corrupted. Sweet. I looked for solutions but the main two I got (EFS Pro and ADB nvrestore) require a backup of the EFS (Which I don't have).
The other solution I got was to restore to the stock ROM (M919UVUFNH7) which I'm currently downloading from SamMobile (Sorry if this is considered spam). The phone is not rooted and has the stock ROM, it came with a CWM folder inside the internal memory with an .img file but it doesn't have CWM intalled. I've never upgraded it (Not sure if it came with that firmware from the store if it matters).
I live pretty much in what can be considered a "3rd world country". So I cannot send it to Samsung nor I have access to dollars.
Another question is, the phone was gifted to me already unlocked, I don't know if it came unlocked from the original carrier or if it was unlocked via a code or whatever. If I restore to the stock will it lock my phone to T-Mobile again? Would I be able to use it without a SIM card if it gets locked? It's impossible for me to get a T-Mobile SIM on my hands should I ever need one. In the worst case scenario that my phone gets locked, can I get it unlocked by flashing a custom ROM?
I have so many newbie questions that are already answered in other threads, but since it's a lot of information I want to get it as specific as possible to avoid breaking my phone.
If someone can help me with this issue, I'd really appreciate it.
i having same issue in M919
Do you guys get a message in notification bar about sim car removed or something about a sim card? Also, it doesn't matter if the sim card works in another phone. This device has a little issue with being picky with sim cards. If it's a cut sim card, get an original micro sim card

Hi, thanks for answering. I don't get a message about a removed SIM card. I'm also using an original micro SIM.
I already downloaded the Stock ROM but I haven't flashed it yet.

This is a known bug of the s4. It is a hardware problem and I have yet to find a solution. If you google it you will find many threads on different forums addressing this issue. Again, no known solution
Any answer/idea about my issue? . Sometimes I can access Mobile Network Options, sometimes I can't. I can't configure the APNs (They delete themselves after I click on save). Phone Serial Number didn't get deleted (Which is stored inside the EFS folder as far as I know). I also can't select a Network Mode. I click on GSM/WCDMA/LTE but it changes automatically to nothing.

That's what I said? One solution is to change sim cards if using a cut sim card to use an original micro sim. It's worked for a friend if someone I know and also for others on XDA. It's not the solution, but works for some

I would get a new sim anyway if I could. Flashing stock firmware wouldn't hurt as well

Before trying to flash it, is there any risk of getting simlocked again? I wouldn't want to get my IMEI fixed just to realize that my phone is locked to TMB again
UPDATE 1: My IMEI and Baseband randomly got back (My IMEISV was still missing) but after I restarted, they got deleted again.
UPDATE 2: Rooted, went to EFS, didn't find nv_data.

Invalid SIM card error

I got Moto z2 force from USA that was on sprint, it was working fine with my sim for some time but with last android update i got "Invalid SIM card" error and now I can't connect to my mobile network at all. I had some problems with SIM reading pins but it was fixed, i am worried that it got locked to Sprint again so my first guess is to unlock it, and I haven't been able to find any way to unlock it for all networks.
I am open to changing rom or installing custom one if that would fix my problem.
Ok, after much messing with a lot of stuff i found something that worked.
I had to remove my sim card, install clean system (I used NASH_SPRINT_OCX27.109-48) and after that insert SIM back in and it worked just fine.
Hope this will be helpful for someone else.
