Ugh my dumb customers!!! Please help - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hey fellas, ok so heres my deal, i have a nice Galaxy S3 i747 that i sold to a customer, i previously unlocked it by downgrading modems and doing the 197328640 trick, and everything was fine, the customer is using it on Solavei, which im sure you all kn ow is a tmobile carrier, so then she calls me and tells me the phone is saying "phone not allows mm#6" so i had her bring it back and i just gave her another S3 to get her out of my hair, so doing my damage control, i look at the phone, and she did exactly what i emphasized not to do! which was updating OTA, and now the phone is on 4.3, so as of right now ive flashed the 4.3 insecure kernel, since i cant go back otherwise ill brick the phone, and i need to RE-Unlock it, however when i try to flash an earlier baseband everytime i boot into the phone it says Basband version: Unknown, so i reflashed the MJB Modem, but i cant unlock this way.....Any ideas?

[Q] Help! Baseband/IMEI lost

i have a bell galaxy note 2, after i flashed some custom ROM, my phone stop working, i have found similar problem on the sprint form, but doesn't know how to fix, please help.
Problem #1:
After flashing a ROM, the GN2 is unable to activate the radio/modem. The following read "Unknown" in the "About Phone" menu:
Baseband, Network, Mobile Network Type, MEID, IMEI, ICCID.....etc. Basically anything to do with the mobile network.
Problem #2:
When booted up and running, PC will not recognize the phone as usual (unable to copy files to phone).
i try odin a bell stock still doesn't work, and when i boot into recovery it keep saying is a RWC rogers phone, does that have something to do with the problem? i also try kies too, still no luck.

This has nothing to do with development.
However unless you have a backup. You'll need to return your phone for a new one.

sorry i posted wrong place, where can i get help, i am new to this, and how do i delete this post
Make sure you odin a rom that included the radio and kernel. Preferably a return to stock type thing. If that didn't work did you back up your efs partition?
Also what did you flash exactly?
OP please read the Forum Rules on posting in the correct Section, Moved & Thank You
I had same situation as you few days ago, I messed up my Rogers note ii with flashed 7100 rom to my i317m. I lost baseband, network imei. Luckily, after I flashed root injected FACTORY Stock rom to my rogers phone, the problem had been fixed, here is the link where you can download the root injected FACTORY Stock rom for you phone. Hopefully, you will get your phone fixed

i flashed a rogers rooted stock version rom on my phone, so now after i did recovery it just keep on shows is a RWC in the recovery mode doesn't matter which stock rom i flash, and its saying a BMC in the download more product name. so its really messed up. because i unlocked the phone from bell, so the guy at bell told me i void the warranty on it. now i don't know what i can do to fix my phone.
Pit CSC file
any idea where i can find a pit file for my bell note 2 so i can repartion it, or that's something only samsung has it
This was a big issue with the gs3 and they've come up with a solution in that thread so given the similarities I would think that would work with some tweaking for the different partitions on the note 2. Check out the gs3 forum & maybe get in touch.. they might be able to help.

[Q] First timer with restoring Rogers GS3 to factory but keep unlocked

Hey there!
So here's my situation: I recently got rid of a Rogers cellphone plan and decided to sell my GS3. Someone I know, immediately showed interest and decided to buy it from me. Good! At that moment, the device was locked to Rogers and was running stock Samsung GS3 (SGH-i747M) firmware.
That person decided to play with the phone, try to root it, flash Cyanogenmod or whatever it may be, and having failed several times, he decided to return the phone and get his money back. I shouldn't have accepted to reimburse him knowing how much he fiddled with it but I did.
Anyways too late now. The good thing is that I believe the phone is 100% functional (it boots, runs perfect and under system info shows everything as usual except under Status > Device Status, it shows modified.
I am not 100% sure of that what means but I believe it has something to do with a modified ROM or something like that.
That person supposedly unlocked the device because he was with another carrier.
Now I am putting the phone in the classifieds. Obviously I would like to have the phone back to 100% factory settings and ROM, no aftermarket stuff whatsoever BUT I'd like to keep it unlocked (if that's possible).
That way, it will be easier to resell.
So here's my questions:
What does "Device Status: Modified" really means?
How can I find out if the phone has been altered in any ways?
If it has been altered, is there a LINUX based procedure to restore EVERYTHING back to factory?
If I restore whatever has to be restored, will it re-lock the device?
As you can see, I am a total noob in that field. I would appreciate if someone can help me to prepare this device to be resold.
I don't want to cause any problems to anyone, that wouldn't be fair.
I appreciate. Thanks!!!
Okay a lot of questions, you can download the stock firmware from Samsung updates and if it is rooted you can get triangle away on the play store and reset the counter the using kies or the Samsung galaxy s3 toolkit from mskip's to flash the original firmware, your phone should be unlocked as none of the procedures should/could reloj the simple card

Ok I have verified with an app called Root Checker Basic, and it said that the device wasn't rooted. I wonder if this is reliable.
I wiull check mskip's toolkit or Kies to restore the stock firmware.
What a pain..
Thanks jimchee for replying!!
Actually it's pretty easy but you can probably sell it just as easy if it's rooted and that way you can clear the counter, there is also a post in the Samsung sIII THREAD for AT&T that will walk you through restoring to stock, just make sure you download the file for your device the link is also in the att thread, if you have any trouble pm me and I can help, I am just a tinkerer but been doing it since my 1st original Motorola Droid
Sent from my SGH-I747M using Tapatalk 4
Probably the easiest approach would be to look for the Samsung S3 V7.0 toolkit post. This is a flash (programming) tool. It would easily root your phone if it needs that. Then you can use the app referred to earlier to reset the phone to an "unmodified" status.
Then finally go to the Samsung updates site as suggested and flash the phone with a stock Rogers firmware. I'd recommend a 4.1.1. version. Probably your phone will still be unlocked at this point. But if not, the stock v 4.1.1. Rogers firmware will allow you to unlock it again from an onscreen menu (search for "S3 unlock code *#197328640#"). And your phone will report an unmodified status at the end.

basic question about unlocked At&t note 2

So, I have an i317 At&t note 2. It was originally on 4.3, but I wanted to unlock it. I followed some forum posts and reverted back to 4.1 and was able to unlock it. It worked with a tmobile sim on 4.1.1, but now when I try to update it (either through Kies or through update on phone), it updates but then gets stuck at the samsung galaxy note 2 display. I found another forum post (thanks, but cant find thread atm ) which had a file to download. I installed that using Odin, but that only got it to work on 4.1.1.
I guess my question is I have the note 2 running on 4.1.1 that I factory unlocked, but now it wont let me update. How do I get 4.3 on it? Thanks
Ok there's plenty of 4.3 Rom's in the development section...
Just have to search for them!
Q: »»»»
Is it rooted?
Do you have a custom recovery installed?
Are you sure your familiar flashing Rom's?
Etc etc etc......

It is not rooted. All I have done to it is downgrade it to 4.1.1, then unlocked it. Is there a stock ROM. I want to be able to go into settings -> about phone -> and update it that way whenever a new version comes out and not have to install custom ROMS. Is that possible?
No, I don't have a custom recovery installed and I am not familiar with flashing Rom's.
I thought I could downgrade to 4.1.1, unlock, then update to the newest stock version through updates in the phone, but thats not the way it works when you unlock the note 2??
thanks
Pardon me if I sound ignorant. I am new to android (switched over from apple a month ago). The note 2 had 4.3 on it. I followed thread
http://forum.xda-developers.com/showthread.php?t=2014982
to unlock my phone, but had to revert back to 4.1.1 in order to do so. I followed posting
http://wccftech.com/guide-to-downgrade-firmware-on-samsung-galaxy-devices/
to downgrade to 4.1.1. That went successfully and I successfully unlocked the note and all was good. It was running 4.1.1 and I was using a tmobile sim. I went to updates through settings on the phone and tried to update. After that point, it just boots up to "samsung galaxy note 2" screen. I used Odin3 v3.07 to reinstall 4.1.1 and its working again.
I would ideally like to be able to go through software updates on the phone to update it and not need to use custom roms. Is the problem I am trying to update from 4.1.1 to 4.3 and I need to manually update to 4.2.x first, then go to 4.3?
I don't understand why unlocking it prevents me from updating from 4.1.1. I have tried through the phone and through Kies, which keeps getting an error. Does this make sense? Am i doing something wrong? The phone is originally At&t. Do I need an At&t sim inserted to update through the phone?
thanks for all the help and once again, sorry if these questions seems elementary. I am reading through forum posts and trying to understand what all this means. I'm not sure what rooting or flashing means and how flashing is different then unlocking.

What is unclear is why ware you trying unlock it, what carrier it was on and what carrier you are changing to,
You're asking if it needs an ATT SIM to update, so I'm lost on what carrier it was on.
The original carrier is at&t. I unlocked it and now am using a tmobile sim. However, when I got to settings and check for updates, it says "checking at&t servers for updates". So it is working for tmobile now, but only on 4.1.1. I don't mind downloading custom roms (and definitely appreciate the work), but I would like the option to not have to.
And when I boot up the phone, even though the network says tmobile, it shows at&t start up screen when it boots up into 4.1.1. Which is why u was thinking maybe the reason it won't do updates through the phone is cause there is no at&t sim inserted when it is "checking at&t server for updates"

Well, over my head here. I think you have figured out technically why it's not working.
You are operating on a T-mobile network and you will not see ATT servers.
Even though it's says you are on T-mobile is anything working? Like texting, surfing or cell calls?
I would imagine texting is not since the config should be pointing at ATT servers.
I would think you should be running one of these factory images

I personally do not know if the T-889 is close to the ATT Note 2 model.
You may want to bounce over to this forum
http://forum.xda-developers.com/note-2-tmobile
See if anyone has attempted what you are doing.
In my mind you need to flash a T-mobile image to do what you want.
I am not suggesting you do this, I am merely giving you an opinion.
You may want to investigate this custom ROM

Yeah, I dunno. It's an i317 on at&t. And it was definitely on tmobile cause it let me send text messages and it showed "tmobile" across the top as well as their 4g icon.
All I was trying to do was unlock my at&t note 2. Now its unlocked but stuck to 4.1.1. Lol

At&t/ s3/i747

Hello community, I have looked for the stock Samsung s3 I747 AT&T firmware. I have found it but its a download from Hotfile, which has been shut down. I was wondering if the android forums could provide me with the Stock firmware? I plan on using Odin3 in installing the firmware. This is why I am wanting to do this, it appears I am stuck on edge network. I have manually set the phone to use 4g and 3g it still reverts back to edge. This occurred after I updated to 4.3, so my plan is to install stock firmware and re-do the 4.3 update maybe something went wrong somewhere during the update. If you have other suggestions other than trying to install the initial stock firmware, I am open to anything.

You'll have to have a look in development. Since you already took the 4.3 update, you can no longer "start with stock and redo the update". You will hard brick. AT&T was not nice enough to provide an ODIN flashable 4.3 rom. In development or general is a custom recovery flashable ROM that should help you out, but that is assuming you have a rooted and custom recovery phone. If not, there should be someone along to help.

Re-installing the stock update probably wouldn't help me anyhow. This phone has had a IMEI repair, assuming this is the problem now.
The phone, after a re-boot will do 4g, well at least it shows the 4g emblem, then shortly after it will go to edge. Some people I talked to said it could be a weak antenna or some other hardware issue. I think it has to do with the IMEI repair! Well I guess this phone is garbage, its a shame, it looks brand new, my fault for going the craigslist route
When you say IMEI repair, you mean the IMEI was injected into the phone using NV writer?

Yes. I did not do this myself.
However, I did find another program well actually two programs, QCN Generator and DanX which I created a back up and injected the IMEI number into my back up QCN bin myself. With no luck I am still a 2g AT&T user.
I am thinking that the original QCN back up (the initial) was corrupted or something.
Is there anyway to rebuild a QCN? lets say, someone has a back up of a Sammy g3, and I injected my IMEI to a spare QCN. Does that make any sense? sorry still learning, I have learned this with in 24hrs, I am a Xbox 360 Rooter, not an android guru.
I bought the phone from craigslist, which was a bad idea in the first place. So I am now stuck with this paper weight, I have managed to get this phone in at least a working state. I wish to get 3 or 4g back on the phone. I can re-boot it will show 4g with 3 bars then will drop to one and go back up to 3 bars, then drop to 2,1 then it will then automatically switch to edge. I know this is a 4g area, maybe not LTE, but 4g. I have changed APN settings, also manually set the phone to GSM and WCMDA, Still working on it.

[Q] T-Mobile branded S3 somehow became AT&T.

When I received my S3, it was on a T-Mobile branded stock firmware 4.1.1. I wanted to try CyanogenMod, so I installed it, but didn't like it.
Here's where my problem begins. Upon wiping my phone back to stock to get rid of CyanogenMod, I find that it's now AT&T branded, despite the physical phone being a T-Mobile T999.
I tried rooting it and using CSC changers, but those tell me that the PreconfigUI is SingleCSC, and thus apparently unchangeable.
What I want to do is somehow get my phone back to T-Mobile branded stock.
P.S. I do not have a MicroSIM yet.

Can you go to your phone's settings => about device and check what the firmware settings are? Let's see what you have under firmware version, baseband version & build number. If possible, you may post a screen shot. Did you say you returned to stock by wiping your phone? Hardly seems likely and you would have probably needed to flash some firmware. Would you recall what you flashed?
Thanks for stepping up. My phone's info is:
Android Version is 4.1.1
Baseband is I747UCDLK3
Build is JRO03L.I747UCDLK3
I did not flash any firmware, as I had no reason to.

It's definitely on AT&T firmware. Apologies if I sound like I'm doubting you but are you certain it had T-Mobile firmware when you acquired it? I'd guess it was probably already an AT&T phone. If you bought it in the secondary market, there could have been some previous repairs involving parts swaps. Your safest bet may be to leave it as is and unlock for you use on T-Mobile. Trying to force on T-Mobile firmware now could result in a brick. As it is on 4.1.1, you can easily free unlock it by following the well tested method you'll find elsewhere in this forum.
No apologies needed. I forgot to state that the phone was purchased with the T-Mobile boot animation and bloatware already present, and that the model number printed below the battery is T999. I've got no clue if there was a parts swap or not. Is the method to unlock that's posted elsewhere that you're referring to the one that begins with you dialing *#197328640#? If so, i've tried it but never got the unlock message to show.

There could have been a previous JTag operation involving forced firmware installation on the MB. I've seen previous hybrid firmware involving one or other partition belonging to a different model - e.g. the modem, bootloader or something else but not the complete system.
Yes, that's the unlock method I was referring to. You won't get any confirmation that the process worked at the end. However, if you did it correctly, you would know it worked when you insert a non-compatible SIM card and it works. You should also be able to install T-Mobile apps especially the Wi-Fi calling app which is a really nice feature of T-Mobile.
I'm getting it microSIM'ed tomorrow. I'll see how that goes.
UPDATE: Successfully obtained and installed T-Mobile microSIM. Still wish to replace AT&T boot animation and bloatware with T-Mobile's, though.

OK. I'd be interested in knowing the outcome but I'll be surprised if it isn't unlocked already. Did some further research and there have been some reports of people successfully 'flashing' AT&T firmware on T-Mobile phones, and vice versa. Not sure why this should happen and conventional logic suggests the result should be a hard brick which is indeed the most common outcome. I'll also suggest you boot into download mode and see the information under bootloader. If the device has a T-Mobile bootloader, it may be possible to remove the OS via custom recovery and re-flash T-Mobile firmware.
Download mode currently gives Product Name as SGH-I747. Wiping AT&T OS via custom recovery and then installing the proper one sounds like a good lead. I eagerly await your instruction

If download mode info shows secure bootloader enabled, the phone is, to all intents and purposes, now an AT&T phone. Attempting to flash T-Mobile firmware may likely result in a brick which would require a JTag fix. I was hoping download mode would show it still had a T-Mobile bootloader which could have allowed for safe firmware installation but this does not appear to be the case. Likely the motherboard was previously replaced or it suffered a brick and AT&T firmware was JTagged on. Either way, it would be safer to leave it as is.
Bummer. I'll leave it as is then. Thank you for all the help.
