I have a used Rogers Galaxy S4 I337M (from Ebay) and I have purchased an unlock code from a third party site. The problem is I cannot for the life of me get the phone to prompt me for the unlock code. I've tried Bell and Fido SIMs with no luck (they work on the phones I pulled them from just fine).
I've tried flashing stock 4.2.2 and trying all of the dialer codes I could find. I've also used Samsung Kies to restore the latest lollipop firmware, but this still does not prompt and the dialer codes don't work here also.
I've also tried going into the dialer service menu (*#0011#) and enable PERSO SHA256 ON and reboot, and still no prompt. Foreign SIMs either show "Unregistered SIM" or "Emergency Calls Only".
The only way I managed to generate a prompt was to do an NV rebuild from the service menu, and the unlock code said it was successful, but the phone still refuses to get any service. The phone does see the networks when I got to Network Operators, but it fails to register or says "unable to connect, try again later".
Can anyone help me get this phone working?
You confirmed that the model # is sgh-i337m in download mode?
The imei from the dialler (*#06#) matches the imei on the label under the battery?
The imei from the dialler is blacklisted?
Tried flashing the latest ROM using Odin?
Tried unlocking the phone using the free method with regionlockaway?

Thanks for your reply, looks like the imei is blacklisted (hadn't thought of that). I guess I'll see if I can get myself a refund.
If you want to keep the phone, try to have the seller get it removed from the blacklist database.

There was no need to purchase the code as there are several threads here on how to menu unlock it. But since we are beyond that, I'm guessing the other SIM is not provisioned and has no service on it. Try using a friends T-mobile SIM. That's how I was able to check the menu unlock method.

Thank you for your answer.
I used a regular size Vodafone SIM which I just used in Europe last month, on my other phone, so that SIM should be ok.
However I used a SIM cutter to transform in into a microSIM . Visually looks ok too. Could it be that in this process the SIM (now microSIM) got damaged somehow?
When I first insert it, I was prompted for the unlock code, which I typed, got an ok message, but that's about it.
Now says "emergency calls only" and it does NOT prompt me for the unlock code anymore.
Original ATT SIM works just fine.
There's more: I just put that Vodafone microSIM into my wife's phone (which is unlocked) and it works fine.
So bottom line, I used an unlock code which apparently worked (got the message "network unlock successful") but the phone does not appear to be unlocked.
I will definitely try a T-mobile SIM as soon as I find one, but in the meantime which is that "secret code" to check network status for this phone?
*#7465625# does not work and returns "connection problem or invalid MMI code"
Thank you
anybody has the answer to my question ?

Hello,
I bought my Note 3 mobile and decided to flash C-Rom!
At the morning of one day I flashed the rom successfully. Later I installed all apps I wanted. I have my phone rebooted a lot of times with no problem. Some time at the afternoon of the same day I pick up the phone to stare at it! I activated the LTE option and deactivate it again. This was not the first time of doing it! After that the network signal was missing! I rebooted the phone, but it doesn't ask me for a PIN any more. I used my sim at another phone and it asked for a PIN. I used another SIM at my phone but it didn't ask for a PIN.
After dialing *#06# at Dialer a popup dialog shows up. The title of this dialog is MEID and the content is B0000000!
At settings>About phone>Status> the MEID is full of zeroes but the IMEI seems OK.
At the same screen i see the following:
Network - Searcing for Service
Mobile network type - Unknown
Mobile netwok state - Disconected
Service state - Out of service
My phone number - Unknown
MIN - Unknown
PRL version - Uknown
ICCID - Unknown
Thanks everyone in advance
Very strange.... without doing anything like flashing stock or modem?????

The reason is unknown but it seems like your phone lost a valid IMEI/baseband.
Can you check the Baseband version?
Try to flash the stock firmware, or flash the baseband for your device.
The problem suddenly appeared and that's what makes me feel uncomfortable. The baseband number is N9005XXUENC2. I will try to flash whole firmware, but does anyone know how can I flash only the baseband? I don't want to stay with the original ROM!

Extract modem.bin and NON-HLOS.BIN files from the stock firmware, and flash via Odin.

It is my first Samsung. Could you be more specific? How can I extract those? Can you guide me through?

Do you have the stock firmware file already?

Finally I was able to solve the problem. It is a problem with C-Rom and 4g option. I am going to write a new reply by tomorrow and also to the forum. I appreciate the help guys.
Thanks a lot
The problem is with the LTE activation/deactivation.
I am from Greece with COSMOTE provider. Here, in Greece, at the moment we have to pay an extra fee to the provider in order to have the option of using 4g. The steps as I believe are the following:
1). I am not paying this fee at the moment so I am not able to use 4g.
2). I activate 4g and immediately I deactivated it. I did not want to open it, just touching the selection at the notifications. This option is at the notifications when you slide down the notification bar using 2 fingers.
3). Then the signal goes off and I had to re-flash stock rom once again before flashing the custom rom. The problem has to do only with the signal and everything else works as charm in the C-ROM.
The C-ROM version which has this problem is this C-RoM-KK-v7.1-20140622-hlte.zip
I have an unbranded unlocked s8 that I got off amazon. I tried flashing the firmware to att (following the "switch to any carrier firmware 100%" post) to get wifi calling. After flashing it I was able to get the wifi calling option but whenever I click on it I get an error saying "Oops! We can't turn on Wi-Fi Calling for your account. Think this message is a mistake? Ask the person who can make account changes to call us...". Now my question is can this be fixed by giving att a different imei number? Currently they have the number for my unlocked s8, so say if I give them the imei number from my friend's att s6(he is currently using) would this feature start working?
Side question: I downloaded Phone INFO and Original CSC code is blank and Firmware's CSC Code and Active CSC code are both ATT is that how it's supposed to be? Also in download mode CARRIER still says XAA do either of these things matter?

Does it matter if I give them an imei number from a phone that is currently being used on their network already? And do imei numbers ever update automatically or once I tell them the new number it was stay that number even if my phone actually has a different one?

Reason why ymmv is because some people said they have put their spouses imei number and it has worked. Others have said it reverted back to their original imei number.
When the phone tries to register for wifi calling, the IMEI of the phone needs to match the one ATT has registered to your sim card. Chat with ATT support online and give them your new IMEI. After they make the change, wifi calling will work.
I bought used S8 that had clean IMEI (not blacklisted), it was locked on Sprint and with financial eliglibity. Before I got it unlocked it didn't recognised any sim card, after unlocking it did regular setup on my ATT card with all the ATT apps but it doesn't have service. Then I tried with Verizon SIM and it did the same, regular setup but no service. What do you think what's the problem ?
Phone build number : R16NW.G950USQS3CRE2
Is it rooted, and if it is, have you uninstalled any system packages
If not, try a factory reset and making sure the sim is active and APN settings are working and you have chose a network

It's not rooted, I did remote unlock with unlocking service and they flashed original firmware on it, nothing should be messed up.
I did factory reset few times as well as network reset. I double checked APN info and ofc it's setted up together with card.
I forgot to mention that phone is not showing up IMEI, actually nothing when I type *#06# in dial
that mean you lost imei ....flash factory firmware by yourself...it will do the trick

Can you explain me which one I need ? What about bootloader, is it the same ? I've checked thread about bootloader and mine is "carrier firmware", not unlocked.
Which career search for career. Look at the build number in abiut and search for that.
I'm using ATT and my phone was locked on Sprint, so I flashed Sprint firmware and It's the same. I put the SIM card in, it did ATT setup and all of the apps from carrier but it's still block sign instead of signal sign in top right corner and airplane mode is light blue (not usual blue like when you turn it on)
At least this time it's showing up imei in dialer
I couldn't find ATT firmware, if someone knows there's my build number in first post.
I'm trying to get my SM-G935V to work eventually work on Sprint. I already flashed my firmware over to SM-G935U. However, the Sprint IMEI check says it won't work on their network. At a Sprint store, the rep won't even try at a store to test out a Sprint SIM to see if it works. Would a Sprint SIM work in my phone before having my IMEI whitelisted (if that's even possible)?
My second option while waiting was to use Red Pocket. I got a plan, I got a SIM card, but I got "Error! Activation Error We are sorry, but due to the rules set by our underlying carrier, your phone number cannot be activated on our CDMA LTE service."
The third option was trying to change my IMEI which appears still legal to do in the US, but not possible to do on my phone because it won't bring up Engineering Mode with the codes. My thought was it was because my CSC still shows as VZW. I thought G935UOYM9CSC2 was XAA originally but I can't get that to show up.
Any other ideas on getting off Verizon with this phone?
Flash the Unlocked firmware on it. You will have to use a modded Odin, see the appropriate thread for that.
However, it will not change the IMEI. If the phone is currently locked in a contract... there is no way around.
Changing IMEI is illegal and will cause problems.
I had never switched my SIM card from the Verizon network to another one until today. It reboots into recovery and changes the CSC. This is after flashing to SM-G935U firmware. When I was on the VZW CSC the secret codes (USSD codes) wouldn't work. After swapping in an AT&T SIM card, the codes now work. Red Pocket white listed my IMEI no problem. Now if I can get Sprint to do it...
