How to find Serial Number of ATT SM-G920A - AT&T Samsung Galaxy S6

Hello All,
To find your serial number do the following steps. I found this somewhere on the net and would like to post it here.
1. Press volume down + power + home button.
2. hold the home button when you see the recovery screen.
The second steps will allow you to see the serial number of the device.
If you are able to get Smart Switch to work, can you please PM me your serial number. My serial number is not registered with Samsung and at the moment, I am unable to recover my phone.
They rejected my warranty saying the phone was rooted. However, I never rooted the phone in the first place. My Knox counter is 0 as well. I hate Samsung now!!!

cool thanks. always nice to see someone contributing to the forums. may i add an easier way would be to get it off the box or by downloading an app from the play store (for those who do not want to turn the phone off and go into the recovery) also if you go to about device in your settings and then status it has the serial number there as well.

So you are asking someone to give you their devices serial number so you can register it to your own account?
Is it me, or is this completely sketchy?

The serial number is also listed under Settings --> About Device --> Status.

Sounds like you have a counterfeit phone. As AT&T phones have the bootloader locked by Samsung and are currently not rootable.....so if your Serial Number is coming up invalid to Samsung that means your serial number wasn't created by Samsung. You could also argue with samsung if you feel your phone is a legit phone that it can't be rooted as it is an AT&T variant if your "knox" counter is actually 0.
you could also since you can load into recovery, you can also load into ADB and then reflash your phone to the orignal odin version and restore your phone that way.

Locked IMEI

Sorry if this question has been asked before... but is there any way of changing the phones IMEI so one can use it even if the phone has been locked out?
Thanks in advance!
???? by changing the insides of the phone???? It's like a MAC address on a network card, it's there to identify that phone and only that phone. It's pretty much the phones social security number.. I'm sure there is a way to clone the IMEI from another phone but I also doubt any one here will help you do something like that.
prove me wrong..
First, be aware that changing the IMEI of a phone is illegal in every known country.
Second, understand that most users here will assume that you either purchased a stolen phone or stole the phone yourself so you will get little to no sympathy here.
Third, if you are going to say that your from Turkey and don't want to pay the import tarrif to be able to register your phone with the local providers then understand that tax evasion is also a crime so again little sympathy here.
I make no assumptions, simply state the obvious warnings for you.
Also, currently there is no utility to change the IMEI on a Kaiser.
Double and triple what he said above. IMEI change = theft, generally speaking. In the unlikely event that this isn't the case here, please understand that your loss is for the greater good...

Missunderstanding!
I think you missunderstood me, and I am not saying that that is my fault!
Ok, here is the thing!
My friend purchased a tytn II becouse he wanted to have one just like mine, only thing is that somehow he got his locked! So now when he boots up his phone it asks for a password that he does not know, and someone told us that the IMEI is locked and it should be replaced!
That replacing IMEI=theft is to me something completly new!
Sorry for that!
I am not good on how to unlock phones, even tho I do know my way about computers, and I think that this is a very good phone indeed!
I also have a HTC Advantage (X7500)!
Is the phone asking for an unlock code? This has nothing to do with the IMEI. Is the TyTn II unbranded? Or is it from a specific carrier like Orange?
If the phone is from a carrier that is different from the SIM your friend is using, then all you need to do is check out the thread on this forum regarding performing a SIM unlock on the device.
Should he try putting his sim in the phone to see if it's a sim lock?
See now that you've given more info you might get somewhere.
This could be a few things.
If the device is SIM locked then you need to simply insert a SIM from the original carrier and it will continue to the OS.
If your friend applied a password to Windows Mobile then you should be able to do a hard reset by following this:
With the phone off, press & hold the two buttons above "Internet Explorer" & "Messaging" buttons (they are the tiny top ones between the two phone keys & the D-Pad)
Now turn the phone on. Release the two buttons when you see the white screen with the following text:
This operation will delete all your personal data, and reset all settings to manufacturer default. Press Send to restore manufacturer default, or press other keys to cancel.
Now press the Green Phone Key.
When done it will prompt you to press Send again to restart the phone.
At this point you will be like it was when you first opened the box!

Okey, I told my friend to try a hard reset but he asked me what will happend to all his contacts?
Is there a way to back up the contacts before doing a hard reset?
Thanks in advance!
search for pim backup
If he can't get into the phone then the answer is no.
FWIW, if he did lock himself out of the OS then a hard reset is his only option. Currently he can't sync or anything because the OS is locked.

even verizon couldnt fix.....

after i got my droid about a year ago, all i wanted to do was root it. I didnt read enuf about it and the effects of messing up, which i did and "bricked my phone".....so what happened, I was using an RSD lite method....very dumb and unplugged the phone to early (of course messing it up). Finally got it to boot back up and when i had to make the call to re-activate it my service was through U.S. Cellular!?! Took it to verizon, they said that was weird and tried to re flash it with their stock system...didnt work, they called their tech support still couldnt get it fixed. They sent me a warranty phone and didnt want or take the old phone back. It works just fine and i use it as my "test" phone. It is still on U.S. cellular service though. Dont eally need it activated but if anyone knows how, i would love to know??

you could try flashing the 2.2 sbf on it via rsdlite, since its not bricked, or you could flash a verizon radio via recovery after rooting it. Flashing a verizon radio on it should reconfigure it to verizon's settings. Feel free to pm me to further discuss this.
edit: usually when they send you a warranty phone they want you to send the phone back within 10days to avoid being charged for it
Go into recovery, and there is an option to wipe the radio data (i forget what it actually says)​ Try that. You might have just messed one of the parts of the radio by a small amount.

where do you see that option? its not in clockworkmod recovery. under the advanced tab there are choices to wipe dalvik battery stats and report error of the recovery but that is all. also an option to record key gpio values.

[Q] Unable to send sms on Galaxy Note

My apologies to the administrators for double posting. I posted in the wrong forum.
I am unable to send sms but can receive on my rooted Galaxy Note N7000.
When I check the Phone Information by dialing *#*#4636#*#*, the SMSC: field is blank.
If I click on refresh, it returns "00".
If I attempt to enter the number manually it just returns "update error".
I'm assuming that the number is stored on the SIM card and for some reason the phone can't read/access the stored number. This happened once before after rooting the phone and all I had to do then was hit refresh and update.
I re-checked from time to time and saw that the SMSC field was blank sms messages were sending correctly.
I tried installing Gingerbread 2.3.6 but I'm not sure is this was completely successful. The Settings > About Phone confirms the version as 2.3.6
but
1. it made no difference to the SMSC problem
2. all my settings, data and apps are still there.
3. the phone is still rooted.
I assumed all that would get wiped with a f/w upgrade. The instructions I followed said the phone would be reverted to non-rooted. I guess I must have got something wrong.
I talked to a guy at my local telco today. He spotted that the phone was rooted so was quick to blame that (maybe correctly) as the cause. However, when I showed him the settings page revealed by the *#*#4636#*#* string, he thought this was some software app I'd installed myself and not the phone's f/w till he typed the string on his own phone and saw it for himself.
Can anyone suggest a fix? Un-rooting? Wait for the next official Android upgrade for my phone/region?
Thanks in advance
Trevor
is your Msg center number is correct?
Go to Msging - setting - msg center number - confirm it with your operator/other person using same network.
Hmmm, interesting question. I checked with my telco today and they confirmed the correct SMSC number is 96197777 or this number with the country code prefix, +65 96197777. I'm in Singapore.
I checked my wife's phone and this is also the number she has on her SIM card.
So, I decided to try a trick I read about on the net last night. I put my SIM card in the wife's phone and manually entered 96197777. Then put the SIM card back into the Note and hit refresh (the SMSC field is always blank by default until I hit refresh).
The number that came up was 06915669917777!
I don't recognise this number but it works. I put my SIM card back into the wife's phone and it shows the number I entered - 96197777. I wonder WTF is going on.
Thanks for replying.
UPDATE
I just realised you were talking about the Settings in the Messaging App itself which I missed. Apologies for not reading coirrectly. The Message Centre number was blank so I've now entered +6596197777 and sent a message successfully. I'm still confused about which number is being used though. Maybe the one on the SIM card is ignored but if that's the case, why was I able to send messages with NO number entered in the messaging app itself?
Sorry for the long winded story.

[GUIDE] How To Restore Service If You've Lost Your MEID - MEID/IMEI:0 MEID=0

Ok, So if you are in the shoes I just stepped out of, then you've lost your
MEID/IMEI.
If you encounter problems during flashing, upgrading or downgrading you may fall victim to your MEID/ESN being zeroed out. The usual cause is pulling your battery while stuck on the white LG Software Update screen.
How do I know my MEID is zeroed out?
If you happen to be using LGNPST, it's fairly obvious from the info on the right hand side. If you're just using your phone, from the Home screen click: Menu -> Settings -> About phone -> Status and look for the following:
MEID HEX: A0000000000000
or
MEID:0
or some variant
Congratulations! You're zeroed out!
How do I repair it myself?
This is the way I did it, and it was fast and easy..
This is assuming you already have all your drivers in place
Google and download the newest demo version of DFS CDMA TOOLS ,download it and install it.
Pay for it or whatever you need to do
1. Connect your phone in debug mode.
2. Run DFS
3. Connect to your port phone through its debug port.
4. Now click the play spc button, to send the spc of 000000 or put whatever your spc is in that box and hit send. You will see device unlocked.
5. Now in the programming tab, then general tab, under the lock codes section, click on reset, then click write to clear all codes, then under the MEID section, click read. You will see all zeroes here.
6. Now type in your MEID hex, dec, and pESN as needed, then click write. Also Type in your IMEI at the bottom if you have one and click write. These are located under the battery or on your factory box. You will see that the the software automatically converts your meid to (p)esn and meid dec and fills these boxes automatically.
7. After this completes successfully. Your MEID has now been repaired.
8. Click Reset at the top and your phone will Restart. You should now boot back up with service restored and your MEID back in place.
This should be stickied because A LOT of people have had this issue and it took me 10 hours of searching to figure out this solution. There are other solutions that take A LOT more effort and work/using adb and more... but this one I figured out on my own... this is straightforward and easy.
Thanks, Gary

I'm facing the same problem here,, how to find IMEI? (I put bold and blue colored font on step 6)
EDIT: just pulled out the battery and I found my IMEI ...duuhhh so stupid.. LOL
now I can write the IMEI on my Revo, but when I checked with DFS Tools show 00000 on ESN.
something wrong with what I did? *sorry for bad english
thank you so much i am finally able to get ota updates again i thought i was a goner
Works wonderful and super easy...Thanks for the instructions.
So yea, the number have worn off from behind the battery, I got the IMEI number, but that's it. not sure what to do. Since it seems i need the HEX/MIED/ESN, whatever you wanna call it, as well
This tool works with GSM devices? Dual SIM?
I followed this and I unlock the phone with my SPC, but when I want to write something I get a cps_error bad_spc_mod. Anyone else experiencing this?
will this work with HTC ONE M8 sprint ??? i have the DFS demo Only ??? Please Advise

Forgotten pattern to start Samsung Galaxy Note 9. Need to recover data. Options?

Hi all,
I have a Samsung Galaxy Note 9 SM-N960F.
I use fingerprint recognition, face recognition and a pin number so hadn't needed my pattern for a while.
My battery ran out. I charged the phone, restarted, it asks for pattern and after a number of failed attempts, have 1 left. Before I try one last pattern and have to do a factory reset (and lose all my family holiday snaps over the last year), is there any way I can get into the phone and recover the data?
There is a dearth of rubbish and click bait on the web. But if anyone can help, I'm told it's XDA. I have a samsung and google account - both linked to phone, remote access, a backed up OS (but not photos), but can't connect - presumably because it has not booted up. Any help appreciated! - & no I haven't enabled any development options....
is it rooted, do you have twrp on it?
i am copying this from other website. you can try this method.
If your phone is connected to a Wi-Fi network and it is linked to your Samsung account then you can unlock your device’s screen remotely from the Find My Mobile website.
Use any computer or mobile device with Internet access, open a web browser and go to http://findmymobile.samsung.com. Click on SIGN IN.
Click on MORE.
Click on UNLOCK MY DEVICE.
Enter your Samsung account password and then click on UNLOCK.
Depending on the network and the state of your device, this process may take a few minutes. You will receive a notification and the screen of your mobile device will be unlock.

I don't think it would be possible sadly. You have not enabled USB Debugging so you can't flash anything. Also OEM Unlock is turned off. It doesn't work via remote control as the phone is not booted up pass the lock screen at least once. How can you forget your pattern ? Try to remember it or guess blindly, maybe you'll catch the correct one. Also if you do eventually get in again, turn on auto restart once a week. That not only helps to keep performance in top shape but it will ask for the pattern once per week when it auto-restarts so you won't forget it again.

Isn't it you need to enter pin number, not the pattern? Pattern is more secure than a pin?
