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!

My friend has a Samsung GT-N7108 that he bought here in China. He wanted me to install Google Play on it so he could install more apps. I transferred the .APK file to his phone, installed, and GP won't work. Surprise! So, we have to flash a new ROM to his phone. Only 1 problem - it's the 7108 which is apparently specific to the Chinese domestic market. I tell my friends to bring me when they shop for phones...but noooo, they never call me and buy crap phones like this.
Seeing as this phone is different than other phones in its line, which ROMs are safe to flash? I really don't want to brick my friend's phone...
The N7108 has a different radio unit configured to use China's own version of HSPA called TD-HSPA, which uses TD-SCDMA rather than the WCDMA the rest of the world uses for HSPA.
As a result, N7100/N7105 roms won't even work/boot on an N7108.

Are there any replacement ROMs, anywhere?
Well, actually, I suppose any hackers would be Chinese, and thus the instructions, etc. would be all in Chinese. Oh well, my dumb friend's fault for buying without doing any research first.
Hello,
is there an any custom rom for this device with google play and other european language ?
Thank's
Anyone found a ROM for this thing?
pleas assist to root gt-n7108
I'd love to get the Tab S 8.4 LTE (T705) but the LTE support in North America is severely lacking (only 2600MHz is supported by both my carrier and the device. I would also want 700 and 1700/2100).
I've seen mention of an "M" variant for South America (mostly Brazil) that also supports the NA frequencies but I'm coming up blank on a suitable source to purchase one. I've found a bunch of what look to be carrier websites but nothing in English and the prices, after exchange, seem to be significantly higher that what I can buy the non-"M" model for.
Does anyone know what the physical differences are between the "M" and the base version, if any?
Are they actually different or are they just using a custom radio firmware in the "M" to support the SA frequencies?
Would it be possible to flash an "M" radio firmware on the standard model to change the operating frequencies?
Thanks in advance.
Good questions, I have no answers, but the new AT&T model might be what you need. Carrier bloat beware.

Never mind carrier bloat, it's what they're taking away that concerns me.
It looks like, in typical fashion, they have disabled the phone features of the device. I don't see any mention of being able to use it as a phone on the pre-order page and the one picture of a home-screen does not have a dialer icon.
It's possible that's the SM-T707A, though. Time will tell; this is still a new device so we'll see what happens when it finally gets into peoples' hands.

The photos don't show an earset opening, so yes, no phone features in the ATT model. Well, I'm at the point of waiting for the Nexus 9 anyway before I make a decision on a new tab. I really like my Note 10, but would prefer it without touchwiz/magazine/etc.
Any luck on finding a place to buy it from yet? I can't find someone to ship to the us.
I just purchased mine a month ago. The only place I found it availible was on ebay. If you want the phone version of the Tab S make sure you purchase SM-T705. This is the phone I purchased. Tab S with phone capability, and factory unlocked.
I have the t705m bought in Brazil (unlocked) however I regret the day I purchased this tablet. I can't get along with Samsung useless apps I can't uninstall and couldn't find an alternative ROM for this device.

taking a chance here...
do you still have this item? If so, are you interested in selling it? Thanks
Basically what title says
Got one off eBay, works great with US carriers, but the rom included is from Saudi Arabia, so whenever I try to use Samsung Pay it tells me my cards are not supported.
Anyone know what stock ROM I can flash to it so i can use Samsung pay normally?
Theoretically i could just flash every one until i find which one works but if someone has already done this it would be quite a time saver and im guessing i might not be the only one with this issue.
https://www.sammobile.com/firmwares/SM-G960F/
https://samsung-firmware.org/model/SM-G960F/
I've checked both these sites but none have any Americas or US Roms, Ive used the Mexico/Claro one on my old S8 with good success so that one should work, but i don't see it for this version (SM-G960F, S9)
Any help would be apreciated
XSG works but you will get ads and promotions for United Arab Emirates. But it let me use my US cards with no problem.
SM-G960F/FD is not intended for use in the US so none of the firmware's will enable Samsung pay as they do not have the correct CSC for the US. Obviously you wont be able to flash the rom for the US S9 (SM-G960U) on your SM-G960F as the US version has the snapdragon 845 and the rest of the word (except Canada and China) gets the Exynos 9810.
What you are hoping for is for someone to find a way to replace a CSC from an Exynos s9, with the CSC from the Snapdragon s9. Sorry to destroy your hopes but dont think that this will ever happen.
Your best bet is to use Google Pay (Or just put your card inside your case and act like you've got samsung pay).
Like I said. With XSG it WILL work in the US but with Ads from UAE. I use it that way in the US with no issues.
Yeah I've used other country roms in the us no problem but this one is not working, I am using XSG atm, it may be possibly because UAE doesnt support American Express? I would possibly need to find a rom from another country that does, usually the Mexico one works but it's currently not available and there's no Canada or Panama either,
Hello, guys!
I have doubts on buying a S20, which is on retail demo mode. I know only, that the phone is UK version. Is it possible to repair its IMEI, so that it can be updated after that or there is no chance? I asked a few guys, who have posted videos on YouTube, offering that service, but only two of them answered, and said, that the phone can not be updated after that, if it is European version and that banking apps can not be used on it anymore. Is it true?
Just one told me he can do it possible for update. The CPU is Exynos. The price is 220USD. Is this the only solution?
Thank you in advance!

Usually demo units dont have hardware to even capture signal, so unless you need one for spare parts i wouldnt bother
Well how could I check whether it has an antenna before buying?

Don't buy. It's mostly stolen regardless what the seller say.
Why I say so, s20 is too new in the market for retail shops to want to sell off their demo unit.
So don't even buy it. You'll be supporting a thief.

Yeah, you are probably right, he claims it has baseband and only the IMEI needs replacement. It is not worth the money either, he wants 360GBP for it, repairing Exynos costs another 220USD and at the end it's stolen, it's Exynos and is more expensive than second hand not stolen.
I don't know only how they bring them to retail mode, ruining the real IMEI, to make them non trackable.
S20 demo unit has antenna. And is repairable.

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.

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