Hey guys, I've bought a Note 20 ultra Live Demo Unit to use it with WiFi. I am not sure if there is anything that can be done to get it to accept a sim card or an esim? I've read on the internet that it lacks the hardware for that (?)
Also, is there a way to get it to be updated to the latest Android software (especially the security patches). The current software is dated August 2020.
Thanks for reading the post and for any help.
Can't you turn off demo mode in developers mode? I'm curious myself does it actually have a sim slot etc? I know they don't usually have imei numbers but I'm wondering if one could be assigned.

Demo mode is turned off.
It has a sim slot.
IMEIs are zeros for the 2 sims

That's what I'm curious of if it could be assigned or "repaired" etc. I know here some have a hard time with posting about imei repair etc so don't wanna get into that but I myself done some repairs for myself. Anyways i hope you can figure a use for it that suits you. Idk if you can just download and flash updates or not with it. Never actually had one myself.

Yes, you can assing new IMEI numbers to the mainboard and use features like calling, etc. However, it requires root.

I just bought a phone the guy who made no mention of the fact that it was rooted when I bought it. What is worse is he mentioned that his GF worked for Verizon, which did not seem to mean much at the time. Knowing that here is what i'm dealing with.
I was in a rush when I checked out the phone as I had to meet another person to pick one up for my wife as well. It's the sch-i575 in white 16gb. After having a minute to look at the phone it turns out he had Paranoid Android flashed and the phone was rooted. CRAP! Not what I was looking for and he was not upfront about it. The incredibly strange thing was that with NO SIMCARD the phone was getting 3g signal! I spent all night trying to unroot \ undo what he did. I managed to use ODIN to get back to the stock rom although I think it's still a rooted one since I still have the super user app. I got a sim card from verizon but since it was rooted I did not bring the phone in and when I tried to activate later it would not activate. My wife's by the way is working flawless and when I put my sim in her phone it works fine as well. I had to put the sim in my wife's phone and it activated there. Here is the crazy thing, with or with out a simcard the phone makes calls and has 3g internet only but when I make a call it uses HIS NUMBER!! I'm not sure what the hell to do, what could have he done? Any ideas? Please all help is appreciated! I did not think this was even possible for the phone to function w/o a sim. I'm worried about taking it in to Verizon because of the funkiness. Ty again for any insight...

I thought the I575 was an old slide phone. So A. your in the wrong section of the forum since this is Verizon's S3 or B. you mentioned the wrong device number? I saw phones before working and running on networks without sim-cards but that was years ago. If it is an S3, you sure it's a Verizon device? Also since you see 3g....can you browse around in the browser or make a phone call?

Yes, it's a galaxy s3 16gb in white. It looks like currently I was using the tar66 using ODIN. I'm reverting back to the bone stock one now. As far as the models go isn't the SCH-I575 the Verizon version of the S3?
I'm waiting on the stock unrooted rom to take through ODIN and will report back. Thank you for taking the time to try and help.
Ohh, yes the internet works and when I make phone calls with or with out my sim in it makes calls successfully but the other guys number shows up. What the heck did this guy do to the phone!
Our model is the SCH-i535

You are obviously absolutley correct. I'm frantically trying to figure this out. I have flashed the stock rom and don't have super user anymore. The problem persists with the guys number.
Could he have flashed a custom kernel and modem or does reverting back using the stock rom cover all that ?

The one i linked covers all that and completely erases all data on the phone. Did you insert your sim after the stock flash?

I just double checked and I had the I535VRLAG1 version, yours is the I535VRALF2 in the link you posted trying this now. The crazy thing is that it even says that the sim is activated with MY number! but the calls are still comming from him. I even tried wiping the device and clearing the cache. I also tried to JUST flash the modem with VRLG1.modem.tar.md5 and nothing :\. Waiting on the file from your link to download and will try that.
Is it possible that this is being caused by something on Verizon's end? The phone ( with out the SIM ) is registered to him somehow? I know this is not normal but because his GF worked for Verizon could they have done something funky?
Yeah its definitely possible its from something she did to the phone but most likely nothing from Verizon's end. Does the IMEI number under status match the IMEI number under the battery?

Yes IMEI is the same in the OS as behind the battery.
The curious thing is that on the same screen in the OS where you find the IMEI there is also a field called Network and it says " Unknown"
It also has things like:
Eri v : 5
Mobile network type : EvDo-rev.a:8
The thing I keep coming back to is how is it possible for this phone to make calls\ have data with out a sim?
Starting to really think I got cheated
Cheated? Sounds like you have free Verizon service.
Roll with it. If you really want a bill you can have mine...

Just did and the same thing happened. I went to the Verizon store and the guy there had no idea and got me in touch with tech support from the store. They were dumbfounded and flat out said that what is happening is impossible. "It's impossible to make\receive phone calls with out a sim unless they are emergency" I harped on the fact that I am making phone calls as one of their other customers and that this is a big deal. In the end since I had the insurance and extended warranty they will ship me a new phone.

I bought an infuse 4G in 2011 in USA then, the same year, I brought it with me in Italy, I unlocked it and it worked since then both in USA and in Europe. I deeply love this phone.
A month ago I accidentally broke some pins of the SIMM socket and then I thought to start using the infuse as a guinea pig to play with android and customized roms.
After many issues and trials and many "return to stock processes", I finally managed to have a working CM9 installed on it. It worked so well that I decided to repair the SIMM socket to use it again. I brought it to the repairing shop and I've got it back a few days ago.
Unfortunately, both with the american and italian SIMM cards I can only call the emergency number (911). Basically it can not register to any network. (btw I'm currently in Italy)
To my understanding if I can call and talk to 911 it should mean that the repairing was good.
I also called my provider to see if my IMEI number is blocked for some reasons but they have confirmed no bad records.
I tried returning to fix things following several guides like:
UCLB3_Unbrick_1.1
Odin_UCKE3_v2
No Voice or Data service after install of CM9 - ##72786#
Recover EFS
but I don't see any way out. The problem is still there and it doesn't change, doesn't matter what I do or what ROM is installed.
Unfortunately, I'm kind of lost here because, apparently, everything works and I don't have any error notification (or simply I don't know where to look at to make some debugging)
Do you have any idea, suggestion?
Thank you!

My only thought would be did they really fix the pins? Seems one of them still isn't making contact. Return it to stock then return it to the shop where you got it fixed and say you are still having problems.

i second this but if the shop that you send it to was in the US then its gonna be a while till you get it back but if they end up not being able too then i would suggest buying a new infuse since its about $80-100 on amazon which you would be able to unlock yourself then start from there but yea go to that shop and if they say its fixed try the sim in front of them to make sure it is fixed because returning to stock fixes most if not all issues

I should add that 911 will work whether a SIM card is in or not, valid or not, working or not. Emergency Call is a safety feature that doesn't discriminate (will connect to any network available). This is why telco's ding you with a 911 fee every month rather than charging you for using it when you really need to.
Thank you all for the suggestions

ha! that I didn't know and it changes EVERYTHING!! I thought that being able to call 911 mean I had no problem with the SIMM socket. After whatever you've told me I do believe that most likely the problem sits in the SIMM socket.
One question though: let's say that it wasn't welded well, is it then possible that I can see the SIMM number in the settings panel but it's still not working?

Forgot about that listing. Think I know why. Just went to that page, and I get an "Unknown" for that value (and my phone portion is working fine).
So that's mixed information, but a pin not making contact still covers that issue. But what it could be is that Access Point Names or Network Operators is out of whack (these things can apparently stay the same between flashes - or at least restored backups - for some reason).
To get to these two options, go to settings, the equivalent of More... under Wireless & Networks (sorry, I'm not on stock at the moment), and select Mobile Networks.

So I just have got back my phone from the repairing shop and ... it works!!
So I confirm that there was an issue in the welding of the SIMM socket. So this means that it's possible to see / access SIMM information if one of the pins is not connected.
Unfortunately the guy wasn't capable to tell me much about what they did exactly (don't ask, too long to explain ) so I don't know exactly what was causing the issue but I'm pretty sure it was one unwelded PIN.
It's also definitely true that you can call 911 even if the SIMM is not working properly or is not well connected to the device.

Glad you got it sorted out.
So a few weeks ago I bought a pixel for my son from someone local. It was very cheap and my son was using it for school using his mobile data. Today I have then tried to use the phone as I await for delivery of another handset and am faced with some issues. First the phone won’t connect to the WiFi. It’s currently running Android 8.1.0 May security patch and no matter what WiFi wont connect. At times it will say saved network but won’t connect. I have tried to reset the phone but alas no luck. The other issue is that phone is sim unlocked and can use my ee and 3uk SIM cards but the oem option states “connect to the internet or contact your carrier”. Unfortunately I cannot get the person who sold me the phone and all I remember is he told me he bought it from Very UK. Any suggestions please to fix this?. I as under the impression only phones which are sim locked have locked bootloader and also any ideas on how to fix my WiFi thanks.

Seems like you've bought a Verizon locked phone. Those phones has locked bootloaders and recently there was a tutorial on how to unlock those bootloaders. So it can't be done on the traditional way. Here's the tutorial: https://www.google.se/amp/s/forum.x...unlock-bootloader-verizon-pixel-t3796030/amp/
You say you're running may security patch see if there's an update first to June. The non Verizon phones got that already on Monday.
Another thing you could try is to do a factory reset and don't restore any backups at all. Because some backups tries to restore previously remembered wifi. So try that and connect to the wifi. If all this doesn't work then you could try to enroll into Android P beta and see if that fixes it. If that doesn't work then it's an hardware defect. If you cannot get a hold of the person who sold you it then I'm sorry to say that's probably why he sold it to you cheap as he probably knew about the problems it was having. I personally would try to get a hold of him first.

Bootloader unlock has nothing to do with carrier. If you could use 3 UK Sim then you're fine. Unlocking bootloader is only needed to flash custom ROM with some exceptions. Are you able to turn on WiFi and see your wifi but not able to connect or does it not turn on at all?

Hi thanks WiFi can be turned on but it won’t connect. At times it says connected and just saves the network. Mobile data is working fine so completely lost, and now trying to flash the P beta.
Just tried android p and same issue. WiFi will try and connect and just end up with saved but it won’t actually connect. Any other ideas please?

Have you tried pressing the wifi name and then press forget and try to put in the wifi password again. Is it the same issue on all wifi? Like at home, school, friends home or only at home? If it happens everywhere then I don't have any more ideas. My thought would be that it's a hardware defect. Is there no chance of getting hold of the previous owner?

They would probably only need the IMEI number, but if it's out of warranty they'll refer you to a repair center. Wish you all the best and hope that they'll be able to fix it. Let us know what Google says if you do contact them. Keep us updated please.

Thanks will update you as soon as I have spoken to them. The person I bought it from did say it was only bought last year from Very UK and it also looks mint. Has anyone had any dealings with Google RMA with phones without receipt?
I think its a network band issur. Is there a way to switch or unlock them?
Since it's your buddy who is having this problem, not you...
You should ask him to contact the nearest OnePlus official support center.
This gives him the chance to describe what happened exactly to a tec pro and the best chance to solve his problem without losing any data on device.
If he can't do that, ask him to backup any useful data on device, read any useful posts here [ https://forum.xda-developers.com/f/oneplus-8t-guides-news-discussion.11585/ ], and try to get his firmware a re-flash.

Lol, I find your comments funny. No I am not my buddy and the phone is not bricked, EU, and India have diffrent LTE, 5g bands and he didnt realise that while making the purchase. Now with the Indian simcard the phone doesn't connect to the network. And if you dont have anything but a snarky comment keep it to yourself.

Sure, relax.
The thing is, there are many potential reasons for this phenomenon, that your buddy's phone can not recognize any sim card:
1. Broken sim card, which is not likely because your buddy tried many sim cards;
2. Broken sim card slot, which is only repairable by tear down the phone and replace the slot itself;
3. Broken integrated circuit, this is hard to locate, especially if you work on a boat, the salt from the sea breeze can get into the phone and corrode the circuit, and this is not fixable;
4. Broken software, might be:
4.1. baseband firmware, which can be repaired by re-flashing the correct firmware (aka using msmtool, or fastboot commands);
4.2. android system application, if your buddy has modified or disabled some critical application, it may cause the sim card stop working too.
5. And many other possible reasons.
And you speculate that the reason is 4.1, but you're not providing more info.
Besides, it's your buddy's phone not yours, your buddy is actually the only person who knows what happened exactly before and after the glitch comes out, no one else can speak for the litigant.
So over all my suggest is, try to use msmtool to re-flash the whole system and see if it solves the problem.
If the problem is 4.1 or 4.2, your buddy's device would be repaired, and this method is way easier than typing fastboot and adb commands for beginner (many users have caused their devices to be completely bricked rather than stay dysfunctional by executing commands they know little about.).
But if msmtool can not fix it, then the problem might be in hardware (aka 1-3), it's better to try contact OnePlus after-sale warranty to have it replaced or refunded.

I reckon not suitable for India (suitable for EU) cellular profile is activated on device.
Your friend needs to activate one for India using QPST&PDC.

Thank you. That is helpful, I will try this when I get my hands on the phone.
Hello guys. I'm awaiting my eSIM code from my phone provider shortly and I'd like to ask a question (since I'm new to modding eSIM phones) if eSIM is saved in a designated read-only chip.
Example: I'm currently in an unsupported for Google country (where they neither sell Pixels nor support 5G, only VoLTE/WiFi) and would like to flash Calyx into the phone (and also patch ModemFix to unlock 5G capabilities in my country) at some point; Will I lose my eSIM profile? It will cost to retain my number back (10 euros for a new profile). Thank you for your answers!

What do you mean by that? Even if wiping your device removes the eSIM number (which it should), can't you just re-enter the number again? These aren't tied to devices, you should be able to use them in as many devices as you want (not simultaneously, of course).

Pretty sure that it's one time code; Once you download it, it's gone. That's what I know.
Another issue is that I can't physically use my sim because it doesn't work anymore, so my option is to go with an esim or a physical card. And I already have physical card in place...

Yup, you seem to be right. Not sure where I got this information from that an eSIM code can be used as many times as you want.
If you know you'll be tinkering with your device a fair bit, I'd recommend you try to use a physical SIM card. Even if there is a way to carry your once registered eSIM through ROMs, should you brick your device at some point or apply an upgrade that wipes your eSIM, you'll be SOL.
That being said, I've not carried an eSIM registration through multiple ROMs, so I'm none the wiser.
Thank you for correcting me on the reusability of eSIM codes though!

No problem. That being said, I can order a physical card so I can also manually enable 5G capabilities (because in order to get the 5G patch in place, I have to use a spare 5G certified device by my provider to be able to access 5G speeds, I happen to have spare phones).
And in the future, I'll be switching to eSIM because yeah; idk if it will even stay on the phone after completely wiping it. Initially I thought it's saved in some chip but whoever knows please let me know.
