Galaxy s9 live demo

Hello Experts,
I have messed up I need some expert advice. I just bought an S9 live demo. I tried to installed stock filmware and now it is not working. It says installed unauthorized software and now it is not working please someone help me. How can I fix this issue.
How did you buy a live demo phone? Many times these phones don't even have all the hardware like the modem or antennas, plus many are stolen. You can't get support here for a possible stolen unit.
You can get demo units of phones in certain countries and online. I think they can be made to work as retail units. I don't know how.
If it's anything like the S7, there is no Modem in the demo units, and the Fingerprint reader didn't work
So no way to make calls or texts
You could however just flash the F firmware to them to remove the limits of the demo firmware iirc
did the sim card work?
here in Cyprus, they are using normal phones with the stock rom! and if there is no availability the offer you the demo mode(which is a normal phone 100% fully working) at lower price and beter warranty(from store)
try your luck by talking to the person you bought it or from Samsung directly!

A50 NFC version VS A50 non NFC

hello guys,i just wanna ask about the different A50 NFC vs Non NFC,i already have A50 non NFC version and i thinking about to costume or mod my A50 to become a NFC version,is that possible or not? NFC is from the hardware or a software?
thx all
Nfc is a hardware chip so its not possible to make A50 nfc enabled handset
Is that a known fact? Has anybody checked if the nfc hardware is not present in non nfc enabled A50s? Some companies dont enable features in their phones for different licensing issues, but the hardware is still present.
Good Luck With That Move...
It's A Moot Point...
Either Samsung in your Region supports Samsung Pay MST / NFC or they do not.
You can try to flash a different CSC... but I would flash the "Un-Teathered" Firmware version 1st..... then try an Odin Flash of a specific Region's Firmware.
Good Luck With That.. :angel:
If someone figures out how to activate NFC on the non-NFC A50, I would be very grateful and interested.
I bought the A50 in the UAE and never imagined it wouldn't have NFC in the UAE version especially since a lot of websites report the A50 has NFC.
All my phones since 2012 have NFC and I could not have imagined Samsung would not have NFC on a phone like the A50 in all markets.
I guess the first question is whether the non-NFC A50 has the NFC hardware / antenna installed? If it does, then maybe a ROM / region / software solution exists ...
I flashed the Indian CSC rom to see if activates the NFC function in my UAE (non-NFC) A50. It does not.
I suspect the phone does not have the hardware but I cannot confirm this. If anyone has any further ideas for getting NFC working, please share. Thanks.

I think that 505F has diferent hardware than 505FN because 505F is manufatured in India and 505FN is manufactured in S. Korea. So, Im pretty sure that 505F hasnt included Nfc chip on motherboard.
Tearing apart
I teared apart my A505G, and it dosen't have the antenna but there are 2 non soldered contacts. I suspect those are from the NFC, so maybe if I can get the NFC antenna from the European version, it may work. If someone know a repair shop that sells that, please notify me.

SAMSUG S20 ULTRA AFTER I CHANGED THE ROM! PLS HELP!

I have one problem with one s20 ultra 5g ... after firmware uptade from 10 to 11 ...
I bought the phone from a pawn shop and I had a custom firmware installed
I couldn't install many applications and that's why I wanted an original firmware
at phone status I get custom
now I have official android 11 but no signal
is my network blocked? or? I can enter the pin code ... but it doesn't take a signal ...
MODEL NAME SM-G988B/DS
BEFORE CHANGE SM-G988B only. meybe here is the problem ??
someone said it was a roted phone after seeing the phone in download mode
I don't know what that means and how it can be fixed !
Another thing I noticed ... on the back of my phone is written live demo unit not for sale
only now I saw this .... after 3 months from buying the phone
What carrier sim are you using. Big risk buying from pawn shop, you never know what you are getting. Since demo unit it could have been a stolen phone. So many good re-sale options other than pawn shop.
i use telekom mobile romania

If this is a Live Demo Unit it does not have any cellular functions. You will not be able to get any signal - sorry.
