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,
Sacrosaint.

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.
I took a USC SCH-R970 down to the USC store and they unlocked it, I had a sim from vzw already so I put it in and the phone didn't reject it so I rooted with odin and then downloaded a stock vzw rom I545vrufnk1.zip and it worked. The phone thinks its a i545, has my phone number, tries to run through the setup but there's no service actually working. My current phone is still working so I guess it's not really activting all the way.
It says it's roaming, I have access to the secret menus (thanks to shortcut master....mad props) and was wondering if there's a menu to check/edit anything to gain service.

Hi,
so I have an unlocked AT&T G850A that I'm using on T-mobile. When I tried to enable the hotspot, it gave me an error "Mobile data is not available or invalid sim card'. After long research, I learned that i need to root the phone and replace a file. I searched all over the web, but couldn't find root files for the G850A.. I'm currently using PDanet to connect to the internet using a USB, but i really need to get the wifi hotspot working.
IF anyone knows any solutions please let me know.

I am in the same situation but I dont need hotspot on this phone. I remember someone telling me it cannot be done if you are on KK 4.4.4.
But once you update to Lollipop, then the Hotspot will work on T-mobile. I read someone. Maybe someone can confirm.

SM-G850A AT&T Unlock Issue
Hello,
Hope you guys are doing well. I followed the above thread and re-flashed the firmware as recommended. However when I try to enable the mobile hotspot functionality it states that I must contact att to enable hot spot functionality. My carrier is straight talk. I just wondered if they are locking the tether functionality at the sim card level? I was planning on using the hotspot with pda net. I will mention that I left the EFS partition entact since it contains me IMEI info. Not sure if I needed to wipe any other partitions before I flashed this firmware. Thank you guys for all the help.
Thanks,
Coop

I have same problem. Help us someone please . Thanks
The new zvc update blocks the hidden menu. Look in the sprint threads. Do not attempt downgrade or brick will occour. And there is apparantly no zvc tot or kdz yet so no fix. The only option is a 3rd party remote unlock service. That can also unlock the apn menu so you can have data also. If not you will get calls but no data or mms.
The resason for no downgrade is sprint and lg increased the antirollback increment higher so no zvb-zv8 any more.
But as history goes with sprint lgs. Everytime the anti rollbqck goes higher a firmware ussually gets released. Same seems true as for the sprint g4.
This happened to me as well, any luck finding a solution? We already have talked to Sprint, but they say the phone still is unlocked in their end, however the phone still says invalid sim.
Maybe try "Unlock UICC" under the system updates menu? I'm on factory rom with no hidden menu stuff. But had to do "Unlock UICC" even after Sprint said they had unlocked the phone for me.
When ever sprint unlocks and post lg g2 you have to also click uicc. They aprove it but its like a profile update

Hi, i have been trying to find an answer to this after hours of searching i've come up short and confused.
I recently switched from tmobile to verizon, and i paid off my tmobile s9+ and had it sim unlocked. When i put my verizon sim in it, nothing really happens. either it tells me that it can't register on the network or to insert a tmobile sim card.
I have tried using reset and factory reset. I have also tried the method of holding the volume bixby and power and doing a factory reset, then putting the sim in, rebooting, etc. That doesn't work either.
I see several people trying to go from verizon to tmobile, but i haven't been able to find anyone going from tmobile to verizon, and what method i need to do to get this to work, if its possible at all. Any help would be so much appreciated!

Use Odin to flash U1 and then go back to U. Just leave the SIM in. Don't use HOME CSC.

That still may not help, remember Verizon is still CDMA and the T Mobile branded phone does not have CDMA bands activated and they may not even be on the phone, I don't know. Granted band 13 should work fine, being LTE, but could the sim be looking for a CDMA radio and that is why it is not working?

The hardware is identical for all US Galaxy S9 phones. Any bands that may be missing will be resolved by flashing firmware. OP could also just stay with U1 if they want unlocked, and all bands would still be there.

As per Samsung chat support, I've asked if the dual sim version (international) will work with Verizon. I've also asked the rep if I can switch carriers with a locked phone. They said that essentially, all phones were manufactured with the CDMA and GSM band compatibility, it just needs to be unlocked and the US versions will work on any carrier in the US and the international version (dual sim) needs to be unlocked and it will work with any carrier in any country.
That said, it seems that you're just having an unlocking issue - which is good and bad. I hope you figure this out. Try using Odin 3.13, get the CORRECT firmware for U1 or U(VZW) to flash your phone

Only one small correction to what they told you: The 965F (international), will not have CDMA capabilities. That might not be a problem on some US carriers. But if you can't get VoLTE working on VZW with 965F, then you're dead in the water, since you don't have 1x CDMA calling to fall back on. It becomes a data-only device. I don't have experience with it, but I wouldn't be surprised if the VoLTE doesn't work on US carriers. For GDM/WCDMA carriers, you'd probably be just fine with 965F. Even if VoLTE doesn't work, you'd still be able to call.
Hope this helps.

Thanks for your reply, any idea where to get these? I'm seeing all kinds of universal stuff and people saying carrier specific don't exist, etc etc. If you happen to know i'd be extremely grateful

Step 1
Can you find out the exact model number?
For T-Mobile, it will be one of these :
SM-G965UZKATMB (Midnight Black)
SM-G965UZBATMB (Coral Blue)
SM-G965UZPATMB (Lilac Purple)
The U is the important part, as a previous poster explained that the F models do not have CDMA support (forget what that actually means, just know its necessary for verizon)
Step 2
Next, make sure that the carrier version is correct.
Example: SM-G965UZKATMB
BST Boost
VZW Verizon
ATT ATT
USC US Cellular
ACG C Spire
TMK MetroPCS
VMU Virgin Mobile
TFN Tracfone
XAS Sprint
TMB T-Mobile
XAA Unlocked US
SPR Sprint
CCT Xfinity Mobile
Essentially, you need the firmware that starts with SM-G965U and ends with VZW
Step 3
I'm not 100% sure on how to flash from carrier to carrier but there will be a list of directions. You may need to do some research there to see if it will void samsung warranty (aka 'trip knox') or anything like that, if that matters to you. I think only a modified version of Odin will be able to do this.
Download Odin v3.13.1
Extract the firmware file you just downloaded. You should get 5 files:
AP (System & Recovery)
BL (Bootloader)
CP (Modem / Radio)
CSC_OXM (OXM CSC file, will wipe your phone)
HOME_CSC_OXM (OXM CSC file, will NOT wipe your phone)
Add each file to it's respective field in Odin v3.13.1. Use CSC_OXM if you want to do a clean flash and HOME_CSC OXM if you want to keep your apps and data.
Reboot your phone in Download / Odin mode with the following button combo: POWER + VOLUME DOWN + BIXBY
Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a blue box will show up with the COM port number.
Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot.
Click the start button, wait for Odin to say 'PASS'. Once the flash is complete, your phone will reboot.

Hey thanks a bunch, I’ll give this a shot when I get home tonight. It very well may be that the rom I got wasn’t the right one. Other threads I’ve read seemed to indicate that everything was universal now and by having the SIM card in the phone while flashing, it would download the carrier specific stuff automatically. That part at least doesn’t appear to be the case since the phone wouldn’t accept it. But I’ll download some of the carrier specifics and see what happens. Thanks again!
Did you get it to work after all?
Sorry that i forgot to update! I did get it working, but it required a bit more discussion and help on a reddit discussion someone started. I noticed that someone asked this exact question and i pointed him to this thread where he was able to get it working, then helped me with which roms he used, and i got it working as well! I've been using it daily for almost a month now. Thanks so much for everyones help, i hope that if anyone else is trying to do this, between the two threads it can help.

Awesome gigatigga - thanks for getting back. I'm on the verge of trying this. I owe some money on my S9 plus on t-mobile but before i paid it off wanted to make sure all is good.
How are the speeds? Everything working ok? Thanks again! :good::good:
Edit: I was all set to do this and during the signup - I found out that my imei wouldn't work in Verizon's system so they used one from another phone. He advised that if I wanted to pay for insurance, if I make a claim it could be an issue because the imei numbers won't match up. Seemed like a big red flag to me. So I didn't go through with it. Wonder how others are handling this?

Can someone help me?
I cannot network unlock a T-mobile Samsung Galaxy 9 plus which has never been active on any plan. When I insert my Verizon SIM card a system notification says "Invalid SIM card. Network Locked SIM card inserted".
I want to bring this phone to Verizon where I have an active plan. I don't have a plan with Tmobile and my friend gifted me this phone. I flashed it to Samsung stock firmware and bought an unlock code from DoctorSim. The code applied successfully however the phone doesn't unlock completely and continues to prompt for the unlock code when I insert the Verizon Sim card. When I called Tmobile they said only a phone active for 40 days on their network can be unlocked using the phone app and that my friend would have to call them to unlock the phone.
