Galaxy S5 SM-G900F loses signal

Hi recently i've bought a samsung galaxy s5 SM-G900F. Telephone was branded Vodafone (italy) but reads every SIM card (except Vodafone, i think who have sold me has stopped to pay the monthly installment o i don't know). I've tested my SIM card (Wind) with the branded firmware and it worked fine (i've tested for 15-20 min). I sbranded it so i flashed with ODIN 3.09 this unbranded firmware G900FXXU1ANE2 (got out in may, now on sammobile there's a new version of August i've didn't tried yet G900FXXU1ANG9) the installation has done succesfully. Now sometimes when i call someone after i called the phone says "not registred on network" and compare a triangle and then in 15 min it reconnets. How can i solve this problem?

Flash with the newest firmware
Not nearly enough information to do more than guess. You have to either provide a lot more detail about your configuration or watch for patterns to develop to narrow down the possibilities.
The advice to try a newer firmware build is good and may well resolve your issue.

SIM isn't working/Null IMEI

I updated my note 3 from 4.3 to 4.4.2 using Odin and IMEI is null and SIM isn't working. I almost tried everything on the forums.
It's N9005 32GB
CSC Code is XSI
I tried like 30 different firmwares, including all of the UAE(XSI) ones and problem still remains.
Phone isn't rooted
Plus when I flash a modem, Odin says PASS but in the phone info it remains the same as old.
I went to Samsung store, they said this model isn't available in the country, so they can't do anything.
Any help?
Yes search on google ...

Help please... Note 3 n9005 BTU doesn't detect my network operator after flashing

Hi guys,
At the beginning thank you for taking a look and spending your time reading it - I'm just trying to be precise.
Just to clarify - I've spent 11 hours yesterday and 10 hours (and counting) today reading and browsing XDA and different forums, searching/figuring out/trying to find solution,
but I think I gave up on my own and will need your help.
Few days ago I bought myself another same Note 3 SM-N9005 (primarily locked to EE, but unlocked with provider), as my old one (which was factory unlocked).
I had issues with signal (after slight water damage a year ago) - not major, but annoying enough to make me get another one.
So I switched to new Note 3 and decided to check new custom ROMs on my old one.
First I installed stock 5.0 - all worked fine, battery life improved etc.
Then tried Fougat rom and AryaMod - and here the problems began. While using one of those ROMs I inserted Polish SIM card.
Message appeared that I'm on roaming, to switch it on/off etc (don't remember what message exactly appeared as I didn't really pay much attention to it at that time)
I recently ordered new pay monthly Virgin SIM card for my partner. When it arrived I've put it in my old Note 3 and "Emergency calls only" message appeared.
I thought SIM wasn't active yet, so contacted Virgin just to be informed that the card is active on their end (I've put it in my new Note 3 and it was actually working).
A bit confused I put my O2 card into old Note 3 and it connected to the network without any problems.
So I started searching for a solution.
I found out that when I searched other networks on my (modified, old) Note 3 it only found O2 - UK, vodafone UK and 3UK.
I checked the same on my new Note 3 and it found O2, vodafone, EE (whose towers Virgin uses) and 3 UK - so all of them.
I thought that maybe EFS, modem, kernel or bootloader have been corrupted/conflicting, so made TWRP backup of my new Note 3 and old Note 3 (for old just to create serial number folder).
Then I replaced old Note 3 backup with new one, so TWRP could find it and restore the whole image from new Note 3, where everything works (Lollipop EE network version).
That didn't do the trick. Restored AryaMod backup - nothing. Old device still comes with "Emergency calls only" when Virgin SIM card is inserted, but it works with O2 card.
I tried different modems, bootloaders.
I checked the IMEI and it's intact.
At the moment I'm back to Stock Lollipop 5.0 [N9005XXSGBPL6_N9005BTUGBOJ1_BTU] and the problem still persists.
When I flashed the stock ROM and inserted Virgin SIM standard pop-up window appeared with network selection where I've chosen obviously Virgin.
When searching now for available networks it comes up again with only O2, Vodafone and 3 - no EE/Virgin.
For some reason it doesn't find/connect to EE towers.
Baseband: N9005XXUGBOJ1
Kernel: 3.4.0-4540543
Build Number: LRX21V.N9005XXSGBPL6
Network: Unknown
Mobile Network Type: Unknown
Service State: Voice: Out of service/Data: Out of service
Mobile network state: Disconnected
Thanks for reading and apologies for long post.
If I missed anything please let me know.
Hope you guys will be able to help and direct me what to do to get it working again
Very difficult to follow your rambling post .
Step one is IMEI the right one .
Two correct baseband and CSC for your network ??

Sorry, I know it's long and quite rambling. I'll start new thread with just quick explanation.
Answering your question - yes, tried different modems and used EE and BTU firmwares.
Phone was bought factory unlocked (new), so BTU version should work, but it doesn't.

Who is mod in here? Sorry, not very experienced in forum.
Thread can be closed - phone after couple of days eventually connected to the network itself. Weird.

Definitely it's an refurbished note 4 N910K SK telecom korean model and probably faked by N910C software on it and the sticker behind battery is fake too.
And i highly doubt the screen display is not original that's why it has issues and god knows what else is not original inside of phone so if you got any warranty return it as soon as possible because refurbished phones are made by chinese companies they buy damaged phones then replaced whatever damaged inside "definitely not original of course"
then they put a brand new body housing so its looks like new then same goes to box and other stuff.
When you are in download mode whatever model shows there that is correct motherboard model.
