Thought phone was unlocked, but not.... - AT&T Samsung Galaxy Note I717

Hey guys - so my brother-in-law gave me an 'unlocked' i717 that was running the stock AT&T Android (he says he was using it with another carrier). I did some research and used CWM to put CM Android 4.2.2 on there. Thinking I'm all good, I ordered a SIM card from Ting and ported over my Verizon number to it. I go to use the SIM card and the phone prompts me for a SIM unlock code! In doing some more research, I found that I should have a Baseband Version, but that currently reads as 'unknown'. I DO have a IMEI number, though.
So what are my options? I've found a few threads about flashing a radio, would that clear up the SIM unlock problem or just give me a Baseband version? Again, according to my brother-in-law he has used this on other carriers than AT&T.
Thanks in advance!

A modem flash and adjustment of your APN settings may do the trick....
Those two items are required for a carrier change...g

[Q] How to Force Sim Unlock Prompt

Hi there,
I rooted my phone. I've installed Cyanogenmod 7 and enjoyed it. However, it is SIM locked. I purchased an unlock code... but now I can't enter it.
This person had the same problem:
http://forum.xda-developers.com/showthread.php?t=1313393
Cyanogenmod does not prompt to unlock even with a foreign SIM card.
The solution was to revert to a stock firmware. Which is great... except for the fact that my phone's model number is:
i5500m.
It's the dreaded Canadian version. I can't find firmware for it anywhere. I've tried Check FUS:
Product Code: GT-I5500YKMVMC
No firmware info retrieved for given data.
Generally it seems like I only have two solutions... and one failure.
The first solution is to find a stock firmware for this phone. Or receive a backup from someone who has the stock firmware with Clockworkmod.
The second solution is to enter the unlock code without the prompt. Is there a way, an app, or a hack to do something like this?
My failure is to accept that there's no reverting. But I don't really want to do that.
Oh, and thank you for welcoming me into your forums. XDA Developers is a really amazing site. I've thanked it plenty of times for saving my ass.
Thanks for your time,

Look closely at the latest changelog and notice that point 12 states -
"Network: SIM lock messages will no longer be ignored. This may help people who have problems using SIM cards that require a PIN unlock."
Good luck

Thank you so much! I missed that update by only two days. I'm sure this will help many people.
I'll edit this post with my results once completed.
Thanks again!
Sacrosaint.
---------------------------------
Results:
So I updated the ROM. I did not do a data-wipe. I inserted a foreign SIM card. It says it's connected but I'm not getting any service... I don't believe it's unlocked, as I haven't entered a code yet.
Perhaps I should do a data-wipe and retry. I'll repost afterward.
---------------------------------
Potential Final Update:
Odd! I inserted a Rogers SIM card into my phone running CyanogenMod and although no unlock code appeared... it worked. Also known as: my phone is unlocked.
Some interesting thoughts concerning this:
My phone model is i5500m. It comes locked to Bell or Virgin Mobile in Canada.
Upon trying the bml5 unlock method, my code came up as "01234567." Others experiencing this problem concluded that the phone was hard locked.
However, it would appear that flashing this ROM effectively removed the SIM lock. That means that originally, the SIM lock was a part of the firmware. That is slightly scary. I wish I would have come to this conclusion earlier, however, as I paid a premium of $40 dollars to unlock it (at least I supported a local business.)
So: for i5500m or Canadian Samsung Galaxy 5 users to unlock their phones, they must simply root and flash a custom ROM. Originally mine was from Bell, and it has worked with a Rogers SIM card. I'll possibly update this tomorrow when I try the phone with a Koodo SIM.
Hope this helps someone out there.

Sacrosaint,
I have an unlocked GT-I5503YKAINU running baseband I5500LUYJP2 and ROM CyanogenMod-7.2.0-RC0-galaxy5-v1.9. I inserted a Virgin Mobile Canada SIM card and do not get Service. With a Rogers SIM card, I do get Service. I spoke to people at Virgin and they said it's because my phone doesn't support HSPA+. The reason it works with Rogers is because it supports GSM.
I'm wonder if there's a way to install the baseband firmware from GT-I5500YKMVMC and still use CyanogenMod-7.2.0-RC0-galaxy5-v1.9?

What the representative said was true.
Virgin is both HSPA+ and CDMA. The Galaxy 5 IS a GSM phone. Its radio will not work with other frequencies.
You will want to go with Bell, Rogers, Telus, Fido, or Koodo, the GSM suppliers, my friend.

[Q] Unlocked S2 Not Registered On Network

Hi I have recently rooted and unlocked my S2. It recognises any sim put into it but if i try to make a call i get 'not registered on network' error. Apart from this the phone is in fully working order. I have set up manually the APN and recognises the sim but still get error.
Any help much appreciated.
Check your IMEI in settings/about phone/status. If it begins with '0044...' (whatever you do, do not post your actual IMEI number here !) you've found the source of your problem.
If your IMEI is OK, two possibilities that spring to mind are the phone is IMEI blocked (check with your carrier) or your carrier hasn't set something up properly at their end (again, check with them).
Hi, thanks for the reply. My IMEI no starts 3533 should this be ok? I also have signal on my phone but in settings says disconnected. I have also tried other sims but have same issue. Do you think i should contact the network or samsung direct or is there anything i can try?
Thanks again

How exactly did you root your phone? Did you flash a new kernel only? Or also a new rom?
Because new roms also tend to flash a new modem in to the phone. Although this is not common, but a modem can change the way the phone talks to the cellphone carrier. Check in your "about" sections under settings whats your "baseband". Note that you can flash a new modem independently from the rom and kernel

OK this makes sense I did flash a new ROM the baseband number is I9100XXLPQ. Does it matter what modem I use and should this match the baseband?
I am having the exact same problem with 2 different carriers, it only shows a 3rd carrier in dominican republic which is claro and i have not been able to test it with a claro sim card, how did you guys resolve the problem.?

[Q] Can't seem to fully reflash SG Note 2 with stock ROM. Help please!

Hi, and firstly, thanks to any and all who offer their knowledge to assist my conundrum.
I recently purchased a Bell Canada version of the SG Note 2 (i317), I am on Telus so I attempted to Unlock the phone. I looked online and found people were having success unlocking these phones for free using the *#197327640# method, (whereby you go into the service mode, turn off the PERSHO_256 and then INITIALLIZ).
I tried this method and the phone then seemed to work with my telus sim, but only for voice, not data. When I put in a Bell SIM from a friend, both voice and data worked fine - which tells me its not a hardware (radio) issue. I also tried using another friends Telus SIM and had the same results as mine - which tells me it's not a SIM error. Also, all the settings in the mobile network area appeared to be correctly set up.
So, my next step was to try and reflash the phone to the stock Bell ROM and then just buy an Unlock code. I downloaded the stock ROM (2 different ones actually) and used Odin 3.07 to reload the ROM. I've tried it several times now, with both Bell ROMs and each time it says it's been successful, but the phone remains in the same, partially unlocked state.
It seems as though by using the PERSHO_256 method I have permanently, PARTIALLY unlocked the phone. I can't seem to re-lock it by installing the stock Bell ROM, and since it's unlocked, I can't get the foreign SIM error to come up to enable me to put in my purchased unlock code.
If anyone has any insights, it would be GREATLY appreciated. Thanks!

You should ask questions about a specific device in its own Q&A. (unless it doesn't have one). Cuz people there have the same phone and will know exactly what to do.
LIFE! IT'S WHAT YOU MAKE OUT OF IT!
Will do, thanks for the tip!

Galaxy Light SGH-T399N not reading any sim cards I've tried

I just got a Galaxy Light for free that I am setting up for a friend, and right after I got it, I flashed it to TWRP, and put in Tiger Lily, then went to CM12. When I popped in her sim (ATT) It didn't do anything, and as far as teh phone was concerned, no sim card existed. I couldn't get into mobile network settings due to the "insert sim card to access network settings" error, except on CM12, where I got the "User does not have permissions to edit APN" message. I did eventually get a few codes to work and got to the basic service menu, where I could verify it was reading a radio. I have tried Tiger Lily, 2 different CM12 builds, and Stock 4.4.2, and it doesn't seem to read the Sim at all. Also, all builds except stock give a blank IMEI when I check it with *#06#. I am thinking it is unlocked, as i don't get a code request, and I swear it was on Boost when I got it, though it could just not be reading the sim. I tried a few other older Sim's, with the same issue, though I don't know if any were tmobile or metro variants.
I am downloading the 4.2.2 firmware now, to retry regionlockaway with the older modem, but, looking to see if anyone has any input on this. Any way to see if it is unlocked or not? I don't want to buy an unlock code if it is already unlocked, plus I can't get to any of the unlock screens.
Most of what I read is so old, that it doesn't apply, so updated info would be awesome. Thanks!

After downgrading to 4.4.2 (T399NUVUANK3_CL2903595_QB2893704_REV00) I did get the sim unlock prompt again. If anyone knows of any software unlocks, would love to know them, else gonna buty an unlock code if I can get a recommendation. Thanks!
For anyone needing the SGH-T399N stock firmware for the Metro edition, here is a link, as it was hard to find. I kept getting T-mobile versions, which will lock you at the boot logo.

Help! Not sure which phone I got from amazon! Factory unlocked or ATT or TMO?

I purchase a like-new condition Samsung Galaxy S9+ phone from Amazon Warehouse for international travel coming up in couple days. I figured I would have a better chance of getting an authentic phone from Amazon than from ebay sellers. I received the phone yesterday, and here is the situation with the phone:
- The box of the phone says "unlocked by Samsung"
- The sticker on the back of the phone has the model # SM-G965UZBAXAA and IMEI number of a factory unlocked phone
- The actual IMEI of the phone however shows model # SM-G965UZBAATT, which corresponds to the AT&T carrier locked phone
- When I turn on the phone, it shows T-mobile screen and has T-mobile apps on it
How do I determine whether this is a AT&T phone, or a T-mobile phone or something else? Unfortunately, I do not have either TMO or ATT sim cards that I can use to check which network the phone works on. How do I know whether this phone is unlocked and if it is will work internationally? I am not sure how to explain the imei of the phone coming up with ATT model number, yet the phone shows TMO screen.
Please help as I need to get this resolved today, and don't have time to purchase another phone. Thanks much in advance!!

put any sim in it and it should work these phones are multi carrier means all the us models are the same if its att imei id say its unlocked since obviously last used was t mobile but if you put any sim in it other than att it should accept it and not say unnsuported sim and or ask for unlock code
to further this as i said the us models are all the same. They have a file called CSC which determines carrier based settings you can put in a tmobile sim and it will repersonalize for tmobile then swap to att and att will show up..
Its the way of the future and actually quite nice as one firmware pretty much covers all carriers other than specific user data which is that carriers apps
it may be unlocked obviously the listing was wrong but xaa is factory unlocked for sims, You can reflash xaa if it is unlocked for non carrier branding,But id put any sim in and see

Thanks for your response. So if the previous owner put a T-mobile sim in the AT&T phone, then would it show the T-mobile screen at startup, and also have the T-mobile branded apps?

Yes the csc files are multi carrier the phone will do a New sim inserted please reboot to apply new carrier configuration
and it will reboot and install the inserted sims carrier based bloat apps

Thanks again! Is it safe for me to do a factory reset on the phone? I wasn't sure if it was rooted and whether a factory reset might brick it. If I do a factory reset, what would it restore to - the AT&T or TMO configuration, or something else?

Yes its safe go into settings and account backup restore it should show factory data reset Thats the proper way to get rig of a google account on the device It will stay as is until a new sim is inserted factory resets have nothing to do with it

I downloaded the phoneinfo app, and here it what it shows:
Firmware's CSC code: XAA
Active CSC code: TMB
IMEI check shows model ending in: ATT
That made me highly confused as to whether this was a AT&T phone, a T-mobile phone or whether it was originally sold as factory unlocked.

Under Service Provider SW ver., it shows TMB/XAA/ATT
I am trying to understand what this means, why would it show TMB, XAA and ATT? Does it mean the phone was originally AT&T, then someone installed XAA firmware on it and used it on T-mobile. If that is true, is there a way for me to verify whether the current installed firmware is XAA?

That is correct. You see it now. The third csc code is the original device. The second is what csc you have running. And the first is or was sim inserted.
Look in settings about phone and software info. At the bottom somewhere it should show you

Yes, what I pasted above is from about phone->software info. It shows the service provider sw version as TMB/XAA/ATT. Thank you!!
