S/N changed? - LG Optimus 4X HD

Ok, so quick question! I update stock ICS 10H euro open on my phone (OTA) some time ago, than i install leaked JB v20A, and back to ICS using roll back method from general section and firmware that is provided!
My IMEI number is the same as at my phone box stickers, but my S/N number is changed? Normal or not?
S/N is for what exactly, and what causes that change?
Thanks!

How can I know firmware version?

Inb4 "check your software number".. some developers has said to me it's just the software of the ROM you're using, not essentially the firmware.
Okay, let's assume it's true, but we can't flash unsigned or MID and CID mismatched firmware without s-off, right?
However, the fact is I'm using a 5.0.2 international version ROM on my originally at&t 4.4.2 s-on phone (build number 6.xx, don't remember) without any problem. And the build number now shows "7.19.401.2" without any firmware flashing.
So I considered software number != firmware number. If I'm wrong, please let me know.
Another method I found says to use "fastboot getvar all" and check "INFOversion-main". I checked, mine is just BLANK.
So, how I can find the firmware version, really?
Never mind, found a great explanation here!

So are you having any problems? You can use different PDA(rom) and CSC(sales code) as long as they are from the same android version. It shouldn't matter otherwise. The baseband version will affect your reception and is region specific(ie. What may work well in one region may not work so well in another) If you want stock samsung firmware, the version you install will replace the PDA, CSC and baseband that you have now.

hey thnx for the reply ..
ahan i see ok hmm i sought of got u but still the doubt remains the same which regions firmware should i download now?
My baseband and IMEI denote germany (unlike my CSC which denotes ireland) so should i download the kikkat version for germany or ireland? i reside in UAE so getting firmware of Germany/ireland that wouldnt be an issue ryt?( as i already mentioned the firmware presently in the phone isnt of UAE either n is either of germany or ireland ... so i know geting of a new firmware of these countries shouldnt ceate an issue bt just want to be on the safe side so i am asking u)

So I'm assuming you really want official firmware. I would suggest a custom rom but it's your choice. I don't think installing 4.4.4 official firmware will be a problem, only with the baseband as I mentioned earlier might be a bit hit or miss as it will be chosen for the region where it was released. Also once you install 4.4.4 I'm pretty sure you won't be able to go back to 4.3. The only thing I can suggest if you are certain you want official is try one, then if you face any reception problems or excessive battery drain or something try another one. You are not limited to Germany/Ireland either: By flashing the firmware you download, you replace the PDA, CSC and baseband.

Firstly ya i want the official one coz want to get back my warranty.i know i can unroot to get the warranty back but still i rooted it for being able to get the official fimware on my wish .. but i will surely check with the baseband thing n confirm whether the one i choose will work well i m my region(ie UAE) or not as u said its region specific( that is what u want me to do ryt before proceeding with a baseband Just being sure ..its my first time so want to be clear mate
The question of not being able to go back to 4.3 has confused me like i was willing to back up my current rom so anything as u mentioned arises, i would easily downgrade ! ?
Lastly i am downloading the offical kikkat (from samsung updates.com) so should i back my efs folder and imei as well?any help with that would be gr8

As I've mentioned before when you flash the firmware, everything is included such as baseband
Regarding downgrade from 4.4.4 to 4.3, I have read reports saying the bootloader won't allow you to install 4.3 as it is not compatible, but I'm not sure, I've never tried it. Just google and read as much as you can if this is important(being able to downgrade)
Always have a backup of efs folder on your pc. This contains important stuff such as imei.

Hi, I have a question. Recently my phone was updated to latest software 7.1 however i wish to return to marshmallow. This firmware that u have available, will it work for my country Trinidad and Tobago? What are the implications for installing a firmware not meant for your country? Also just for confirmation. The firmware software that I am finding does not match my PDA and CSC number.. Will this be a problem?

Please help me with Lg g4 Ls991zv6 - H81520g

I bought a new Lg g4 model h81520g as shown in setting>about phone>software info. I wanted to check for update but there's no software update option, only apps update is available. so what I decided to do is to reflash the stock software to enable update option. I downloaded the kdz file "H81520g" but when I connected it to computer and ran the LGUP it shows another variant which is LS991zv6. I tried to flash the downloaded file, but it gives an error "invalid kdz. My Lg g4 comes with marshmallow on board. the stock recovery works fine, and also the download mode is fine.
my question is: should I download and flash LS991zv6? by the way, I checked my imei in imei info .com and it shows the model as LS991 sprint

Zv6 is lolipop no mm. U need to check the motherboard. Must disasmble the device and see what it says. Bit if the device is working i would leave it be. Its almost more hassle than its worth

Thats what im telling u zv6 is a lolipop firmware for sure no debate there..
Thats why i say leave it be. This is one of those if u mess up u can hard brick it. Theres not a diffrence between mm and lolipop motherboards but zv6 is a lolipop firmware. Not mm.

Not a very descriptive post maybe include what update what you have tried and maybe try reflashing the older firmware back if uts the same bit revision IMEIs don't just disappear By flashing stock updates unless something was already up with it
