LG H815 sim card not recognised - G4 Q&A, Help & Troubleshooting

Hi guys,
Don`t know if it happened to anyone else but maybe someone can help me.
I bought an LG H815 from Vodafone UK > 2 years ago and unlocked it with an ebay code. It worked just fine until February this year ,1 month before expiring the warranty. I sent it to LG UK and got replaced by a new one.
The new one was also locked I unlocked it again using an ebay code but after few days I started having problems with the signal.
I was getting a message "no sim card" and my phone restarted.
First time I thought that the sim mooved and I put it back but it kept on doing like this.
The thing is sometimes is working for a few hours sometimes it`s not working at all.
Tried different sim cards same thing happened with the phone, tried my sim in different phones was ok.
I also did a factory reset but nothing changed.
I asked the guy who sold me the unlock code and he said it might be the sim bracket.
What should I do ? Should I try to flash another kdz or to install Lineage ? Or simply go to a phone service ?
Thank you very much for taking your time to read my post.

unlocked phone suddenly says 'invalid sim'

I broke and replaced the screen in my unlocked upgraded flashed-ROM wallaby and the unit now starts up and reports invalid SIM.
Is there any solution or should I re-flash the rom again and see if that works, hope for the best?
Try the SIM in a different (unlocked) phone, to make sure the SIM isn't fried. If the SIM is fried, you can get a new one from your provider. SIMs do get fried sometimes -- it happened to me a couple months back. Fortunately my provider (Cingular) has a shop just down the road from me, and they burned a new SIM in 5 minutes.
I apologise, I should have said
Sorry, I should have said, it does work in another machine and as I said, it did work immediately I used the xda flashing process to upgrade the ROM in this very unit before I dropped it.
Everything else in the new ROM seems to work which makes it infuriating that it wont recognise the SIM. I even tried calling T-Mobile and asking them if they could see the SIM on their network and they couldn't.
(I even have one of those SIM copying devices they send you free for some unknown reason when they want you to upgrade your service to some kind of higher level SIM card. I was wondering if I should try to use it again but as mine does work, this, like the whole copying device, seemed a bit academic)

[Q] Three Sim working in locked phone. WTF

After not paying my Vodafone bill for a few months, i got disconnected.
As my mobile contract is ending next month i decided to switch over to three pay and go, as they have very good deals available.
I received my new three sim today and tried it in an old Samsung D500 as it is unlocked and my Touch Pro 2 is locked to vodafone.
Well the D500 wouldnt pick up the three sim card, just an 'Insert SIM' error message.
After alot of tinkering with it i though 'F*CK IT'. I'll whack the sim card into my touch pro 2 and see what happens.
To my amazement, the Touch Pro 2 fired up and started downloading connection settings from three to the phone.
HOW THE HELL DID THIS HAPPEN?
I know for a fact that when i got the phone it was locked to vodafone!
Now its accepting any sim card i insert
Any ideas as to why this has happened?
Just interested as to why.
Thanks guys/gals
Hard SPL'ed ?

Hi,
I'm guessing since you are running a custom rom that your device is Hard SPL'ed ? I dont have O.R.D. , so im no expert here , but I think as a result of that, your device is now Sim unlocked .
I know this because i paid for a sim unlock from a respected developer on here who was very helpful , and when i started to run the application, it proceeded to Hard SPL my device . I have to say I hadn't expected that, and promptly pooped myself (i think i mentioned already I'm a ROM virgin ).
Anyway, everything went fine, with no unfortunate side effects, except my phone is now Sim unlocked, and ready for flashing should I ever desire to do so
Regards
Garrickus
Well hey, IM NOT COMPLAINING
I always thought that H-SPL and SIM lock were 2 different things (as a custom ROM/H-SPL is offered free, while phone unlocking on here is at a price)
Its just great i didnt have to pay for it

Finally I brick my E973,, :(

Couple days ago my beloved Bell E973 wont reay sim card.
Here is what happed. the original from bell, but I bought a unlocked code to use my Rogers sim. It's working perfect for 2 or 3 weeks. I love the screen. personal I like it bettter than S3.
I did not root or unlock the bootloader and one day when I put sim card in, it just said NO SIM. I tried with bell sim. same
So I rooted and tried all kind of ROMs, even F180S. that's fun. but still wont read sim.
If anyone buy it as a parts or want to fix it. let me know. I am in Toronto
You tried to re-unlock it ?
Also, if you flashed korean firmware, your radio will mostly be gone.
no really to re unlocked it, since I tried my friends Bell sim. doesnt work

Might still worth a shot.
omg that sucks=( good luck getting fixed
btw
i saw your post on kijiji lmfao !! we live around each other lmao!!
Did you put it in the proper way?
I made the mistake of putting a sim in the wrong way once on my BB and even took it to a Rogers store and then felt like an idiot after the guy pointed out what I did.

It's still under manufacturer warranty

Two things about your phone:
I may be interested in it for parts, depending on price of course. Mine has a dead spot in the digitizer, and as I bought it second hand, LG won't warranty it for me. I'd not want to spend more than the price of a screen/digitizer assembly, so it might be worth more to someone else.
Have you tried a different sim in it? If the phone is unlocked, try a friend's sim card, maybe your sim just died. Edit: missed your reply about trying your friend's bell sim
Have you tried a hard reset?
Have you tried reinstalling the original rom, using the original KDZ file and the "unbrick" method?
Can you browse internet, play store, or use any program with data connection via wifi?
- first, it might be the unlock procedure did it. I had 2 out 5 devices ran into this scenario after doing a factory unlock.
- second, but unlikely and super scarce situations, Bell might have locked up your device's IMEI that caused it. I got one relative that the carrier locked up his phone after doing a factory unlock.
My Rogers E971 stopped recognizing SIM cards yesterday. It is unlocked/rooted. Hoping I can reroot/lock bootloader and send in for warranty service. Still trying to figure it all out.
same problem

I am hoping to set mine back to stock and send in for warranty servicing.
Optimus G sim card inserted or removed all the variations of the device automatically restarts.
Did you notice this situation?
Inhabitants of this problem, removing or inserting the sim card would not open the device?

Woo911, you have used wrong title for your thread thus eliminating people who might know a solution to your problem to ignore the thread, inability to read the sim doesn't mean your device is bricked.

When I first got the phone it would reboot when I inserted and removed SIM cards. It has since stopped doing this.

Just an update. I couldn't figure out how to unroot and relock my bootloader. I ended up sending it off to LG for warranty servicing via my carrier and they fixed it free of charge.

Problems with new SIM card LG G3

Hi there,
I am a so far satisfied owner of a G3 but since 10 days I have been having an issue with my G3 and I wanted to ask around if someone here has an idea or some thought that could help.
My situation is the following:
About 2 weeks ago I switched my mobile service provider. When my new SIM card from my new provider arrived I tried the SIM card in my G3 but there was just the massage "no sim card found" and no possibility to type in your PIN. So I thought maybe I got a defective SIM card, it happens. I ordered a new one but the problem remained with the new card in my G3 aswell, still no pssibility to type in my PIN. So I tried troubleshooting and started trying the SIM cards in diffrent phones. In other phones the SIM card from the new provider worked perfectly and I was able to type in my PIN like it should be. When I tried putting other SIM cards in my G3 (from my Mom, Dad etc. and also from different providers) none of them worked in my G3. Even my sisters SIM card from the same new provider AND she has also a G3. So far it seems that the my G3s SIM card reader is broken.
The weird thing is that when I put in my G3 my old SIM card from the old provider the prompt to type in my PIN appears as normal as ever. If I type in my PIN the phone accepts the PIN normally. There is just no reception which is normal because I am not with my old provider anymore. I also have to add that the phone appears not to have SIM lock. I bought it from a private seller but he bought the G3 with a vodafone contract and I was with O2 at that time and the phone worked perfectly. Just until I switched from O2 to Congstar (Telekom) the problem began.
So I thought I just send it back to LG because I still have warranty on the device. The phone is rooted so I need to admit that it was not that clever to send the phone in without rolling back the rooting. Today I got a letter from the repair service from LG with an estimate of cost which means no surprise, no warranty for me. You guess right, the reason is the rooting they write they need to change the whole mainboard. For me this sound like plain bull**** because on the document they send it seems like the first thing they check is a rooting and if the device is rooted then thats the cause. But ok it was pretty stupid from me not to unroot it, I know.
Now I wanted to ask you if someone had a similar problem with their G3 or has an idea what the cause could be. Like mentioned above with my old SIM card the phone worked normally. Just the new cards and all other cards, even another O2 card did not work. Is it possible that just one and only one SIM cards gets accepted from the phone?
Sorry for the long post. I am thankful for any advice.
Best regards,
Patrick
I'll have my phone back tomorrow. If someone still has an idea I would be very thankful about some thoughts or suggestions.
Thanks!

It seems your phone is Sim locked.
You need to find the unlocking code that you need to put in the hidden menu.
Google for LG G3 Sim unlock.

Hi,
thanks for your reply! Iam not sure it is because of sim lock- Because the phone came with a vodafone contract but when I bought it I was with O2. And with my old sim card from O2 the phone worked perfectly. Weird is that when I put in a different O2 sim card the pin prompt also did not appear. Same with any other sim card ...
Thanks,
Patrick
Or did maybe someone have a similar experience with a different phone?

Hi again,
I tried some more things but still nothing helped.
The things I tried were:
- unrooting the phone and factory reset
- reflash radios
- try completely diffrent rom (CM)
Still I have no idea what the cause could be. Maybe the sim card reader is just broken. Just weird that it reads my deactivated sim card.
I would really appreciate it if someone has an idea or some similar experience..
Thanks!
You can buy an unlock code for 3.5-4€ , works for any LG G3 variant
Try it
Ok, thanks! I will try it!
So I just looked at what I have to do and tried the combination 2945#*855# to see where I have to type in the code. The thing is when I choose any one of the appearing options like netlock etc. the phone says "this phone is permanently locked" and there is no possibility to type in any code...
How the hell is my phone completely locked...

Confused why my LG G4 can't unlock..? It's a new unactivated warranty replacement

I've tried a few services online and none of them can unlock (sim/network) my LG G4 H812 (Canada). Abit long story, but I bought this new from WIND a few months ago, but switched to another carrier (Mobilicity) recently and unlocked it fine. But soon, the G4 had issues so I received a warranty replacement with a different IMEI. During this warranty process, the service center asked who the original provider was, so I said "WIND". I assume that meant that the replacement was locked to WIND again.
OK, np I thought, I would just get the replacement and unlock it again. But for some reason no one is able to unlock it. Is it because this new phone has never been activated with any carrier..? How am i supposed to do it? I no longer have the WIND sim either.
Thanks,

I'm having this exact same issue. My LG G4 was bought brand new from Wind about a year ago, but was sent in for repair through Wind's warranty service. I had the bootlooping issue, so my phone received a new motherboard, and subsequently a new IMEI. For resale purposes, I tried to SIM unlock the phone through multiple third-party services with no luck. I then tried asking Wind for the code directly, which they didn't have (I assume this is because it is a brand new IMEI), so Wind told me they'd request a code directly from LG. I received the unlock code a few days later, but even that code doesn't work. I'm honestly stumped, and my phone's now down to only 2 SIM unlock attempts remaining. Did you ever end up having any success with your phone? Were you eventually able to get it unlocked?

What issue did you have with it to need it repaired in the first place? Since the unlock code that I received from LG directly didn't work for me, I'm a little hesitant about using one of my last two unlock attempts on cellunlocker.net, a third-party service. BUT, seeing as they worked out for you, I'm somewhat hopeful.
