Hello guys I need help im trying to fix my phone one week and still no help, I upgradet my android 6.0 and I got camera fail so I downgrade it to 5.0 with no back up, so stupid to do. I lose my imei code now I got 004 imei code I tryed everything (odin, octopus, firmware change ...) still nothing can it be fixed somehow. My phone is Samsung Galaxy S5 SM-G900H help ! Thanks
 
Did you try flashing the Stock 6.0 again for your model number.
Null IMEI used to happen a lot on S3's and it's usually when the build and baseband doesn't match or baseband unknown.
Reflash of the stock firmware usually will fix it.
 
I tryed to flash it with stock firmware 6.0 via kies but imei stay 004 i dk what is wrong im not so good with softvere problems to be honest, i need help so desperately :( Im doing something wrong but dk what. I live in Bosnia and Hercegovina (europe) and my phone is made in vietnam, i dk what country firmware i need to download or is it same? Thanks for replys and help.
 
Are you sure you used Kies?
If you used the Firmware Upgrade and Initialization in Kies3, and entered your model number and SN, it would have selected and flashed the correct firmware for you.
Take a look at this guide
http://www.samsung.com/ca/support/skp/faq/1072789
If flashing the firmware doesn't correct the problem, there are PC programs that will allow you to write the IMEI number back to the phone, as long as your EFS partition is not totally trashed and you can connect to the program
 
I have all download on my pc but didnt try it all, im gonna try tomorw i just found this
but when i try to connect phone to kies before i put on upgrade its say model dont have inicialization something like that, so i need to put the upgrade first on and than i connect it with usb, im not sure but in this video he put model name and imei, and on my kies i dont see that option only model name and serial number
 
If you follow the guide, you enter your model number then your SN. If it says that your model number is supported, then you connect you phone with your phone in download mode and follow the rest of the prompts.
If your model number is not supported, then we need to figure out the correct firmware and flash it with Odin.
Going offline now. Will check first thing tomorrow, approximately 6hrs.
 
Ok i will try to do it via kies but i think i wont make it since my phone was not supported last time as i remember, thanks for help i rly appreciate it alot. I will inform u about this proces after i try it.
 
I connected the device on Kies im downloading last softver 6.0 marshamallow but when i install it i will have again same problem with camera (the camera fail error) but is this gonna restore my IMIE code ? :/ I hope so.
 
I tryed via kies but im getting F error after 85% upgrade :/
My current version is G900HXXU1BOA7
Karnel version 3.10.9-3660428
 
I'm pretty sure that the O after the model number in your CSC is for open and you should be able to flash any firmware for your model number with Odin.
International and multi CSC devices fry my brain.
Gonna ping the expert @ironass and see if he has any input.
 
Hope it works. I'll be online for about another 1.5 hrs.
If not. Tomorrow we can try to write your IMEI back to your phone with EFS Pro.

After that i wipe cache partiton, and wipe data/factory reset, rebot. Still my IMEI is 004 :/
Do i need to root it again so we can try other solution?
 
That sucks. Don't need to root to try and write IMEI back to phone.
I will need to have access to my PC to try and walk you through it.
I'll PM you when I get home from work and then we can start.
