[Q] Samsung Focus s stuck on demo mode

Hi Guys, i need your help i bought a samsung focus s and it is still stuck on demo mode,does anyone know how to take it off demo mode. I've tried holding the camera button,lower volume an power button together but it hasn't made a difference. And i went to the about option and theres no option to reset factory settings. I've even emailed samsung and they told me to contact windows as it is their software. This is really frustrating, because the guy who sold me the phone well he doesn't know what to say they only had the one, I had read (You should return the phone because it seems you have bought a demo device and not a retail device, also another person said, I'm sorry to say that demo devices are loaded with different software from retail devices, so it will not be possible to get the device into a 'normal' mode unless you have the technical skills to flash the 'phone with a fresh ROM (see xda-developers.com). I wouldn't normally suggest this, but it sounds as if your vendor may have (perhaps conveniently for them) disappeared from the picture. Note that if you do flash the handset you must be prepared to lose all support from Microsoft, the 'phone manufacturer, and your carrier. In particular you will get no support here on Microsoft Community) and thats ok I'm with the prepaid thing anyway...Any Help is Good help
Thank You

sorry to say my friend but your probably out of luck, there is no ROM for us to flash, official or otherwise, we have no modified boot loader to make our own ROMs and there isn't any update cabs to update you to the correct ROM.
the only thing that I can think of is perhaps some registry entry that can be changed, but you would need to dump your reg and email it over.
but to be clear, I don't know of anyone getting them working, its proabably the same device being passed about, if you got it through ebay I would raise complaint if your unable to speak to the original seller
note that even if you can change the device in to a retail device with the use of a reg entry, you still cant change the ROM version so cant update it

Blacklisted IMEI/MEID (bad esn) phones can not be repaired by the user. The imei blacklist is an international list which all gsm carriers have access to. Once the IMEI number of a phone is blacklisted, no gsm carriers will activate the phone on their network. Changing the IMEI number is the only solution but its illegal in some countries (check your local regulations). Even if its legal in your country, you can't (afaik) change the IMEI/MEID of the M7 because there is and encrypted key stored on the phone memory to check the authenticity of the IMEI number. If the key doesn't match then the radio will not turn on.
Best you can do imo, is to sell it as is (bad esn)

IMEI problem - can someone explain/advise?

Short version: who can fix IMEI on my (legally bought) phone?
Long story: I bought a new G870A phone around XMAS from an ebay-like store (I live in Poland). It seems to be an American phone (I get an ATT logo). It worked fine in Poland for two weeks I was using it (Polish SIM, T-mobile operator), but then I left for my work in South Korea, where I have a Korean SIM (SKT op.) it had connectivity issues: phone/SMS/wifi work, but mobile data doesn't work if the phone displays LTE 4G on the top. If it shows just 4G it works. I took it too SKT shops (three), all swear it's not an operator problem. Took it to the Samsung service center, they couldn't figure things out, sent it to the factory. I got a call from them (well, I don't speak Korean, so it's handled by my Korean gf). She said: "the number of INEI on the phone does not match the manufacturer’s serial number on the phone. Based on my understanding from his explanations, the manufactures finds for the serial number with INEI numbers, two numbers need to be the same. If another person is using a phone with the same INEI numbers with yours, your phone might not work properly. Your phone is not in the process for A/S since ur phone itself has the problem. So, they suggested you to contact the distributor what happens." I did some research on IMEI, and I am confused. I am reasonably sure that the place I bought in Poland is legit (I got the box, warranty card, proof of purchase; the business has official government registration, and 99% satisfaction ratio for its ~2,000 sales). The mobile data worked in Poland, which would suggest IMEI was fine - until the flight/SIM change? What could have messed it up? And if it is, who can fix it for me? Seems like the Samsung rep wants me to take the phone halfway through the world and complain to the Polish seller? Should I try to get if fixed in Korea? Whose fault is it? It also seems like it is possible to get the IMEI changed without root, could it be that someone "stole" my IMEI number? Could IMEI numbers work in one country but not the other? Should I try to change the IMEI myself - and if so, are there any good guides for that? I also read that changing IMEI is not legal in many countries, but presumably the vendor/service center can do it? But who is the party that should fix my phone? The original vendor? Are IMEI problems covered through warranty?

[Q] DS and non-DS models difference

Hey guys,
my neigbor has a A600FN model with a "locked" dual sim tray. It has a bar right there where the second sim would go (see here). I´ve checked and the phone has the hardware needed to be able to use the second sim (there are pins). Does someone has tried to use the DS tray in a non-DS model and got the second sim working?

Hi there.
I have SM-A600FN Duos, form a polish carrier. It would seem unlikely that your neighbor's model would support Dual SIM capabilities. If it has two IMEI numbers listed in settings/on packaging/on sticker that was stuck on the casing, then it would be Dual SIM/Duos.
If not I think, that the only way to trigger that capability is to physically open the phone, find some clues if motherboard of that phone has some evident model selection circuitry like some 0Ohm resistors or something. Mine LG K430DSE had those (like you could set it as DS/F/T/TV etc; just by bridging correct SMD pads).
Then, and only when you would do that, wich is kinda unlikely, then you'd need to flash correct firmware via ODIN, and there would not be any guarantee, that the second SIM slot would work at all. It probably wouldn't work, because it wouldn't have any IMEI number registered to it I think.
That's all that I know. If I'm incorrect, then I'm sorry, prove me right.

a.f.a.i.k even flashing "the correct" firmware (for duos) will not working. need some modification in efs etc. etc. there's guide for converting to duos in S7 edge thread. search in s7 edge thread..

It has the neccesary hardware (probably) but you need a second IMEI and it's not easy to make it

Question Dual Sim plus health monitor (ECG, etc) impossible?

I just got a new S21 Ultra dual sim Latin American variant, because no US version dual sim Samsung exists. I have a US Version Galaxy Watch 3 that pairs nicely with it, except when the health monitor app on the phone tries to open for the ECG I get an error saying that it is not available in my location. I verified with Samsung that this is because the phone is a non US variant and there is no way around this limitation (according to them), even though ECG is cleared for use in my home country (USA).
So an idea I am exploring now is to send this phone back (still in return period) and buy a UK variant dual sim S21 Ultra. My reasoning is that ECG is cleared for use in UK and apparently the health monitor app is working for the UK. I asked Samsung tech support and the agent said I would not be able to get through the health monitor "onboarding process" from a physical US location using a UK origin device. She didn't think using a UK IP VPN would help any, but she didn't seem sure. Still it seems like a legit idea to me ... the phone is from an "ECG cleared" country and I live in an "ECG cleared" country. But does logic apply with Samsung . . . I am not so sure anymore.
Do you think this idea would work?
Any other ideas of how I could end up with a dual sim S21 on which the health monitor app (ECG, etc) would work . . . that wouldnt risk bricking my phone?
Many thanks in advance for any help.

So here is a second idea to run past the experts here:
change CSC (currently set to TPA ) to XAA using method in this link:
Change CSC on Samsung Devices | Guide | iHax
Looking for a way to change CSC/Country Specific Code on your Samsung Galaxy device? Here's a quick guide on how to do it easily.
ihax.io
I actually pulled up that radio button screen to see what it currently was, but I chickened out of changing it
1) would this change make my dual sim phone a single sim phone?
2) is there a chance it would be impossible to revert back to TPA if the change caused problems?
3) any chance this change would brick the phone?
4) since I have 2 imei numbers, what is the result of making this change on only one imei?
5) do you think this change would solve the problem of not being able to start up and "onboard" the health monitor app?

Changing a csc from dual sim variant to dual sim variant shouldn't have any impact on IMEI. Almost no chance to brick the phone.
CSC just define preinstalled apps and features (ECG, call recording...)
I would say its worth the try but I can't guarantee anything

thanks for that. Actually Id be changing CSC from dual sim variant (Latin America) to single sim variant (USA). Do you think that would cause issues ... like break the dual sim functionality?

So I backed up and looked at this complete mess Samsung has me in trying to kludge their products into working after I paid a hefty price for them and I made a decision. Im still in the return period on everything. So everything is getting boxed back up for return (chargers/watch/phone/cables/etc). Im going to take that money and put it into a dual sim Iphone12 and Apple Watch 6 which apparently works very well in the USA right out of the box with no complicated hacks. Been awhile since I hitched myself to the Apple Wagon ... we'll see how it goes. So long Samsung. RELIEF!

so i tried the iphone for awhile and I just couldnt do it anymore. so the new iphone went to the wife, and i got a Note 20 Ultra (Tmobile brand) today and the dual sim (using esim) does work . . . BUT
1) you have to endure Tmobile unlock policy nonesense
2) the dual sim functionality isnt as finely controlable as iphone or dual sim androids. you select one which of the esim/sim will be "primary" and it will use data. so you cant have the physical sim as the data user and the esim as the primary voice/sms line.
annoying , but not insurmountable issues.
not a bad phone, but the bronze color is actually more like a pink. a big plus for some would be the expandable memory.
a HUGE con is the price . . . 1300 USD
apparently ONLY the TMobile branded us version Note 20's have the esim enabled.

Have you checked the watch does not have to be from a country that supports ECG feature not the phone?

I cannot confirm whether or not the country of the watch itself has any effect. All I can say for sure is the phone has to be a version from a country that supports the ECG feature.
