[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] can i change my d851 g3 into a d855

So i was wondering if i could change my tmobile lg g3 into the d855 version since everything is for the d855.

Nothing short of buying the D855 will get that for you.

Simply, NO

Well that sucks i use to change varient on my htc one to any one that i like.

Why would you want to? For lollipop? Don't bother with all that if so, just wait.

Lets hope tmobile will release it asap

Well most likely US carriers will be a little while longer. It almost always takes longer for us because of carrier regulations. Also Im sure tmobile will also be adding VoLTE in the update so that maybe could make it take longer as well.

Verizon VS985 stock stops recognizing sim

Any help would be greatly appreciated, this issue is quite obnoxious.
My Verizon LG G3 was running 5.0.1 lollipop just fine until last wednesday.
I was sitting reading a phandroid article at my desk, when a message popped up saying sim card not recognized. I tried restarting, removing battery, and finally removing sim. Sometimes after restarting it would get a greyed out 3g signal and allow phone calls but no data and say entering global mode. I got on the phone with verizon and by the time they answered after pulling sim and doing a couple restarts it had started working again. It worked for a few restarts and a battery pull, but then stopped working about an hour later. I went to verizon store got a new sim card, and it worked phone. I switched it off global because they told me that wastes battery (is this bull**** or true?) it worked for a couple of days, then died again. Then it started working again the next day or 2, and it automatically forced the 5.1.1 update while in my pocket. It worked for a few hours after that then lost sim again. The next day it worked again. Now I can't get it working again.
I should also mention this might just be coincidental, but everytime it stopped working was within 10 minutes of me swapping in a fresh battery. Both of my batteries are official LG batteries, and I charge them with the official
TL: DR
my phone keeps not recognizing my sim and is now running 5.1.1.
Any ideas for what my next step should be?
Should I replace sim a 2nd time?
Should I do a factory reset, is there any chance that would fix this? (I haven't done one since I got my phone and used the image from my first G3. So my phone has done 3 updates without a FDR. But i'd really also hate to lose my progress on some games unless I absolutely had to.
Should I have verizon send it to LG for repairs (takes like 2 weeks) (I think it's still in warranty since I got the phone 12/16/2014) But that was after returning my first G3 i got in september i'm not sure when they start their warranty period
Should I replace it through my asurion insurance?
Other ideas?

LG G4 overheat when wIfI IS ON AND DRAINED BATTERY

I bought LG G4 with my previous carrier T-Mobile. I never had an issue. I love the phone; however, recently I change carrier to AT&T and the overheat issues and battery drained with my wifi started. T-Mobile doesn't want to deal with my phone. AT&T is "no comprendo" or basically this phone is not ours. I contacted LG and after several tries and procedures testing they asked my to reset to factory default which I did. Now my LG G4 still overheating when I use wifi and the battery drained.
Any suggestion other than to buy another phone? I would greatly appreciate any help.
Thanks,
Bernard

Thinking of buying a TWN H815 in the UK... I have a few questions?

Hey folks
Im wanting to buy a new LG G4 and theres a gorgeous BNIB Unlocked Pearl White one in my local 2nd hand store... but its a TWN H815...
I have read around XDA and do know that these TWNs work here, but how is GSM / 2G radio... or will I always have to use 4G?.
Also, as itll be my daily driver, I wont be rooting and I wont be unlocking the bootloader, so will I get OTAs or will have to flash kdz through LGUP,.. which isnt an issue.. just curious?.
Are there any reported motherboard failiures on the TWN versions.. or any Serial nos I should note?
Any help would be great
Thanks all.

Don't buy one. This model runs really hot, has poor battery life and is slower than my older LG G2. Buy a G3, G5 or another non-Samsung brand phone imo.
Without rooting it's not a good device, with rooting - this phone is still far from the G2 as a daily driver.

if you into it. then try getting any from 6XX serial up.. its no guarantee but less likely to happen.
