HI,
I rooted an 747M on 4.3, install a 4.3 rom and sim unlock the phone with cellunlocker.net. It worked, other sim worked.
Then, I want to roll back to the stock 4.3 from nandroid backup. =bootloop.
reflash recovery and screw it, get my custom rom back from the second nandroid backup.
It worked. BUT I DIDNT test the phone with an other SIM...
I sent the phone ti my bro in other country and he said that the phone is locked.
I thought that SIM unlock is for ever , no?
thank you
I'm surprised because I didn't think the phone could re-lock.
Is the owner being prompted for a network unlock code or a sim unlock code?

Hi guys, I got my unlock code from Telus, and am trying to unlock my T989. The phone is rooted and running AOKP-M6. The instructions say to simply insert a non-telus Sim and turn on the phone, it should then ask for the unlock code...
I did this, and its not asking me to insert the unlock code.
Do I need to restore back to stock/unroot?
I dont have the stock Nandroid, can I use any other stock rom?
Thanks!

No you dont have to do anything to your phone...i never unrooted or returnck to unlock a phone...it "should" like they said as soon as your phone turns on with a different sim it should ask to enter a code.
If you can try a different sim.
Did you buy your phone from a private seller or did you get it from tellus?
I bought it from Telus 8 months ago, I'm giving to my sister who's on Fido.
I inserted her sim and its not asking me anytihng...just says that its not connected to the network.
I just dled the Stock ICS Rom...maybe its the AOKP thats not making it work?

I had the same issue on AOKP, I had to restore to my STOCK nandroid backup, and then got the enter the unlock pin screen with a different SIM.
See if it helps.
I dont have my stock nandroid
I just dled a Stock Telus ICS Rom and its installing now...hopefully it'll work!
I'll reply in 10 lol
It Worked!!
Thanks a lot guys
To anyone trying to unlock on AOKP, you need to first restore to a STOCK ROM
Hi guys, I'm trying to network unlock my M8 to use in Germany. I've inserted the card and typed in the network unlock code that I bought. Unfortunately, it is hanging on "Requesting network unlock'
I have tried factory resetting the phone.
What can I do?
Thank you
Are you stock, which carrier?
AT&T Skydragon rom
Try stock rom if you can see if that helps. Do a backup of your current rom, flash stock then restore backup
I'd suggest go back to complete stock also.
thanks, going back to complete stock worked. However my SIM card is locked every time I turn on the phone.
What do you mean your SIM card is locked? Do you mean you have to enter a pin to unlock the screen?
Network unlock requested?
Hi man,
I have the same problem.... Canadian Htc One m8 google play edition locked to Bell... I have rooted and unlocked bootloader... unable to s-off...
tried to sim unlock my device and after inserting another sim and unlock code it just hangs on the screen saying " network unlock requested...
Tried everything and nothing helps....
maybe some developers here can figure it our...
So here's my problem. I finally got my code to unlock my network on my Canadian rogers phone but I've realized that I need stock rom to be able to unlock and I am now on Cyanogenmod 12.1 android 5.1.1 with the I747MUMUEND3 baseband and MJB bootloader (I believe). I remember flashing a new baseband/modem to be able to get the CM 12.1 nightlies.
But now I'm stuck in France with a SIM card that doesn't work and I don't think I can downgrade from what I'm seeing in the forums. Once your beyong 4.3 there seem no downgrading/stock possibilities...
Am I stuck with a Galaxy S3 wifi tablet?!
You can flash the latest 4.4.2 stock ROM from sammobile.com, perform a factory wipe, boot phone with non-Rogers sim, enter the sim unlock code.

Sorry to ask you but I can't seem to find it. I've been searching and I found firmware
http://www.sammobile.com/firmwares/download/9102/I747UCDLK3_I747ATTDLK3_XXX/ but
I feel like that might not be it... And I'm scared to brick my phone!
The Rogers s3 is the Sgh-i747m.
And this gets it down to just the i747M releases by Rogers.

Nevermind I had to factory wipe wich I did and now I have successfully unlocked my phone. Thanks a bunch guys. Much appreciated!
So, I was given a i747 A T & T model for my daughter. I was able to get TWRP flashed and made a back up of the stock ROM. I then proceeded to flash CM12.1. Now, my question is this; I got the unlock code from the original owner and was trying to use it but it kept coming back as an incorrect code. I found this thread and realized I need the stock ROM. So if I restore the stock ROM back up, will that be enough to let the unlock code work? Unfortunately, I've already used 4 of the 5 tries, and don't want to waste the last one. Thanks for any information.
You should be fine to enter the code if you are able to restore the TWRP backup of the stock ROM.

Thanks. That's what I was thinking, but I wanted to run it by you folks here. I'd never dealt with Sim unlocking a phone before. My personal phone was purchased Sim unlocked and my next phone will be a Nexus device so the whole Sim unlocking is new territory.

Good luck. We're all here to help each other out. Let us know how it goes.

It worked great! I restored the original stock ROM backup I'd made in TWRP and then performed the unlock and it worked. I'm glad too, since it was the 5th try out of 5 tries. I'm now restoring the backup of the CM12.1 that I'd made for her last night and she's got an active phone. Thanks a lot for the confirmation.
No problem. Congratulations?
Hey I have my sim unlocked I did it using the hidden menu method I have used it on simple and more recently metro. I got a new Nexus so this is now my backup. The other day I put my girls tmo sim in and it worked fine but today I put my mother's metro sim in and it wouldn't get a signal. But it didn't say insert sim. So did I inadvertently relock my phone to tmo by putting a tmo sim in it?
Also I am on cm 12.1 and I don't have a PC to Odin back to stock so is there a way to unlock the sim without having to go back to stock?
No re lock is possible.
There's no way you can relock your phone , it doesn't work that way, once is unlocked stays forever.
Hello
I am currently running CM 12.1 on my SGS3 i747m.
I want to return back to stock rom, the current version offered by Rogers is Kit Kat 4.2.2.
Is this considered a downgrade? (from CM 12..1 to Android 4.2.2) Will I brick my device?
Is returning back to stock rom the only way I can network unlock my phone?
1) it is a downgrade in android versions (lollipop to kitkat. not bootloader/modem).
2) no , will not brick your device as long as not downgrading bootloader/modem.
3) what is your current bootloader/modem version ? (if unsure , you can DL the "samsung info" app from playstore and it will tell you).
http://forum.xda-developers.com/showthread.php?t=2609045
here's the xda thread for that.
4) i belive its the only free method. i think you can pay for an unlock code and not have to return to stock.
5) if returning to stock , here are directions posted by @audit13

"err on the side of kindness"
So you're telling me I do not have to revert back to stock in order to network unlock? =D
That was my only reason for reverting back to the stock rom.
correct. but i've never had to unlock one so i wouldnt know where to go or how much the code cost.
"err on the side of kindness"
***update: i just bought an unlock code
didn't work. my phone says perso lock.
sigh
if i revert my phone back to stock rom, does the recovery have to be reverted too? or it's all good.
Recovery can be custom or stock. You need to revert to the stock Samsung dialler in order to enter an unlock code.
Easiest method would be to flash the latest 4.4.2 stock Rogers rom from sammobile.com, skip through the set up, power off, insert non-Rogers sim, boot phone, enter unlock code, done.
could I install stock rom via recovery or does it have to be through Odin?
so... I tried to install the stock rom via Odin3 as instructed on Sammobile... but it gets stuck in the glowing Samsung logo during boot.
any ideas?
try thru recovery :what:
"err on the side of kindness"
Did you perform a factory reset/wipe in stock recovery before booting the phone with the newly-flashed rom?

i can't access stock recovery
I pressed power+vol up+home button. nothing.
although i get into download mode
i tried this: http://forum.xda-developers.com/gal...13-nightly-t3356062/post66306367#post66306367
and doesn't help =(
Are there any error messages in Odin? You're flashing the correct firmware?

So I went back to flash the latest stock firmware... and I was able to access the recovery and wipe cache and then factory reset/wipe! it worked!
=D
but I am having the same problem I started. I couldn't unlock my phone.
I entered the unlock code I got from MobileInCanada.com... and it still doesn't work.
I see that there is a free method for Android 4.1.1.
I am currently running Android 4.4.2
From Phone INFO app
Bootloader Version/PDA/CSC/Baseband: I747MWLUFOB3
Do you think I can revert back to Android 4.1.1 and try the free method? Or should I complain to the MobileInCanada about unlock code not working. Seeing as it looks like going back to stock, everything should be easy as pie to network unlock.
So you flashed back to a completely stock rom, inserted a foreign SIM card, you were prompted to enter the network unlock code, and it didn't work?
The imei in the phone matches the imei provided to mobileincanada? I have used mobileincanada but it was a long time ago. I get all my unlock codes from eBay because it's cheaper.
Do not attempt to flash any rom that is 4.3 or older as attempts to do so may hard brick the phone. Once an i747m is running a 4.3 or newer bootloader, the phone can only be unlocked with a code.

Yes! completely right! I inserted my foreign SIM card, entered the unlock code from MobileInCanada and it didn't work.
I double/triple checked the IMEI.
Mobileincanada has a very good reputation. I recommend contacting them for a refund or have them resend the code.
Thank you!
would it be a different code?
If you supply the same imei, the code should be the same. Perhaps mobileincanada looked for the wrong imei in the unlock database.
