LG G3 F400s Problem (Fake?)

Okay, so i have already searched the forums and the google but i couldn't get any satisfying answer.
So here is what happened. I purchased an LG G3 f400s (i reside in India) and the device was delivered today. The box contained 2 batteries, a dock, a wall charger, USB cable and the earphones. There is an antenna in the top right corner too.
What i did,
1. When i received the device, i booted it up and initially set it up. Then i went to update center to update via OTA but got an error (screenshot attached below). So, i decided to factory reset the device and set it up again but i ran into the same problem. All the LG apps are updating via update center but software isn't updating to 5.0
2. After a lot of tries, i decided to update via LG PC suite. But even it gave me an error. (screenshot attached)
3. After a lot of brain wrecking, i decided to update via KDZ. I went to this site http://lg-phone-firmware.com/index.php?id_mod=41 and entered my IMEI in check new firmware. Even that gave me an error. (screenshot attached)
I have even contacted the seller and he assures that the phone is 100% original.
Now i have no clue what to do. If any of the community members could help me out, i would be really grateful and would buy you a cup of coffee too. :crying:
Thank you.
PS: Sorry for the bad camera quality..

Should I flash lollipop kdz for f400s?

if you have a box, check imei number on the one of the labels. it might be a fake phone or something related with failed rooting/flashing/unlocking

My device is Korean so it came in a white box as all the other Korean versions come with. Here it is
Also, the ir blaster and laser focus both work....

Currently I'm downloading lollipop kdz.
Is there any other way to check if the phone is original or not?
What all I've checked,
1. Cpu-z, antutu and quadrant all show snapdragon 801, 3gb ram, 32gb Rom.
2. Both box and phone state the phone to be f400s. Even the back of the phone as various places where f400 is written.
3. The ir blaster and laser focus both work.
4. Resolution is 2k. I checked it in details when I took a screenshot.
5. Camera does record in 4k.
The only concern is,
1. Imei is not being recognized on "lg phone from" but on another imei site, it does show lg f400s.
2. Both ota and pc suite are showing errors.
Thank you for your time

could it be a testing phone that should be "not for sale"?

The phone does not have any sticker saying "not for sale" or "testing device" below the battery.. So I suppose it's not that... Should I flash lollipop kdz on it or further wait?

SAME F400s India
U got it from ebay right?
http://www.ebay.in/itm/LG-G3-Korean...6?pt=LH_DefaultDomain_203&hash=item35ea0ca6b0

1more problem for me is EDGE not working. So I asked for return from ebay.
whether EDGE works for u ?
Share ur mobile number to my id [email protected] so that we can clarify doubts.

Anyone?

i have same problem

Same problem. To those with same issue, haven't been able to fix? I had my phone checked in a local service center, and they say I need to have motherboard replaced. But I doubt the hardware is the problem. Anyone have ideas?

Not sure yet what is the problem. Using custom roms and various modems did not help.
No network and phone is quickly discharging and very hot.

Quick discharging of the battery/very hot I think is due to the phone constantly searching for network signal.. I removed my SIM while still looking for a fix, and this helped with the battery.
I can still connect to WiFi but other than that, it's not really a phone if can't do calls/sms..

Mate! Did you find a solution to this problem? I got my phone off ebay.in and after the lollipop upgrade the same thing happened. If you got a solution can you help me out as well?

same here my D855 was changed to D855V by octoplus now need a way back, also here no signal.

Worth a try?
Have the same problem. Asked around in the market from the tech guys. According to their understanding and experience we should try flashing it with a d850 rom as they believe the phone is actually a d850 model. Would have done it but i don't know how to unbrick incase anything goes wrong. so anyone willing to try and if does let me know about the results

Well i just bought the phone last week. For me there is a lot to loose. Right now i'm just not getting signals. Rest of the phone is working perfectly wifi,cam, music etc. =p

Flashing with d850 will kill it, I tried and now dead, it was a d855 and became d855v after octoplus.

Can you please elaborate what you did and what was the result?

I have found a lot of threads and people reporting this issue. Bought a D855 32Gb from China that has this problem...
Phone tries to get signal a couple of seconds and then a cross.. and so on..
I tried everything I think, I passed for all the bricks the phone can do: Automatic Reboot / Boot Loop / Fast Boot / Security Error / Factory Reset Status 2 / Dead (QHSUSB_DLOAD) - I can help anyone that has any of those problems : )
In one of the flashes my phone turned to D855RE, similar case to other people, also the message "Current version is not available for user. Can't find matched cust for NT-Code mcc/mnc".
Please if anyone was able to fix the problem report here, there is a lot of people waiting for the answer 20 threads in different networks, I will post the solution in each of those. Thanks!

no network

Null serial number

Hello guys! I buy sgn4 from ebay. Problem is that imei and phone model on sticker and from phone "about" is different. Network is good, i can make calls, etc. Ok, i think that motherboard was changed. But serial number is only "0" as i know it is factory s/n. What should i do with this device. What happens if i flashed it with custom? I`m afraid that my imei will broke and i can use it only in "iPod touch" mode

I understand your worries. I hate even giving advice on touchy matters like this, because depending on why the imei doesn't match. But I'll go over a couple senerios. For one the samsung serial number is all zeros. Mine is to.
Now the big concern is why the imei doesn't match. It's either the mother board was replaced or someone hacked it. Is the model number the same? Cause that's gonna make a big difference as to what to do.
Lets say someone replaced the mobo, but its not a Sprint mobo, then that's gonna effect how and what roms you flash on the device.
Before we move on, give me more info. In About phone, what does it say for the following:
Software version
Hardware version
Model number
Baseband version
Also do you have Twrp? And/or root?
Get me that info, and i wouldn't flash anything until you figure exactly what hardware the device is and have a full backup plus Efs backup.

Thanks for your reply! The phone about says that i have:
Software version: N910PVPS4DQB3
Hardware version: N910P.05
Model number: SM-N910P
Baseband version: N910PVPS4DQB3
I have no root and stock recovery with ticked Knox counter

the same as my phone, my SN number is array of 0, but the phone is working flawless without any problem. You can try many roms for N910P

oops, i think your phone maybe have some parts that were replaced from the seller. so why don't you contact him and ask about the phone for more information and got the refund if he sold you a bad quality phone ? the normal phone doesn't have any ghost image or blur grid on the screen. And you tell that your IMEI from system is differented from it's sticker ? Your phone maybe hard-bricked and lost IMEI, and the seller used tools to write another Phone's IMEI to your phone.

That all looks good.
Now the back of phone says it's a SM-N910P? Correct?
But the IMEI's just don't match, Correct?
If this is the case, it seems that the mobo was replaced.
The main thing here to know, is if that this is indeed N910P hardware. You should be fine flashing or using Odin!
If you decide to start flashing custom roms, the first thing i would do is Flash TWRP and do a Full Backup (boot,system,data,EFS,modem,cache). And save it in a safe place (like off device, on a pc).
I believe you should be fine, either mobo was replaced or someone hacked the imei so it didn't show as stolen. Either way as long as you don't mess with your EFS, everything should be fine.
FYI, there are no guarantees with flashing! Make sure you research what your doing!
Edit: I just seen your other post about grid. I agree with @zRoNz , the screen could have been replaced with cheaper parts (digitizer) or is a burn in effect.
Edit : 1 more thing you can do. Is install 1 or more Device Info apps. And compare the hardware info they state your phone has. Just to make sure it's truely Note4 hardware!

@aaron74 thank you very much for helping. I just asked seller about this. I think that screen was replaced with no original one. And last questuon: I cant press left sensor button with s-pen. It's should work i think?

That all makes sense now. It's probably because of the digitizer installed. Not sensing in that region. I'm no expert on this, but that all adds up!
If you just bought this, you could try to see about a replacement. But if you can't get one, i would say how much is there to really worry about it. As long as everything is correct except that, how often will you need the spen for just that? It works everywhere else, i assume.
Good luck!

haha sure but i dont know which one is the right firmware, i bought the phone from a local store, without specific carrier for the phone.
also, i was able to find my IMEI written on the back cover of the phone.
is it possible to write the IMEI into the phone and just to make it work?
also, when im entering recovery mode to wipe the phone for new firmware installation, it says ""failed to find /misc partition"

you will get that error message as a ton of us do. should be an "e" in there somewhere.
I've heard of your situation when flashing older modem/bootloader in a custom rom.
You seem to know enough to grab odin and flash, that's a lot more than many so that's good. Not sure who sold you the phone, but if you want to rule out anything shady I suggest running the IMEI to check on the status.
What country are you in? Where did you download from? And did the phone bootloop soon after attempting to use it with a new SIM?
I looked on sammobile and the only information I could use shows multiple countries. My phone bootloops all the time but that's called learning.
Download the phone info app... heck you might as well go all out and put twrp on it and root/install custom rom. Go all in.... i'll be here waiting...
---------- Post added at 04:15 AM ---------- Previous post was at 04:10 AM ----------
Honestly, though... grab the phone info app in the playstore and post the results.
If you THINK it may be stolen and got ripped off, don't put a SIM in it.
Not sure if it is true, but I think it can be rendered unusable if it is hot. But most likely it's just hurtin' from a sour flash. Phone info... (twrp is easy and a touch of magisk will give more info if you get stuck) but I am a rookie.
You in Israel? Can only be one firmware there... flash a Palestinian firmware. It won't... ya know... nevermind.

Confusion on Regions..

Hi guys, im alil confused on how to update the phone correctly. So i thought i had an Indian S9, how exactly would i confirm that? Is it a good idea to check my IMEI from those IMEI check sites - they seem kinda dodgy.
Main reason being i read that if i dont install the correct A10 package for my phone - i wont receive updates and i'd like that to be automatic. ATM i think i have the Netherlands version running on my S9
Thanks

post your entire IMEI up in your next reply. Kidding, never do that. The IMEI checking sites are actually pretty accurate, but if youre unsure, almost all the major players will offer the same service on their sites too, they just call it something else. You can also go into the about phone section and irrespective of whats currently installed, itll tell you how it left the factory

Where exactly is this? - as far as I can tell, everything under 'software information' is relates to the current version of Android 10 i flashed.
