there is a sim unlocker floating around here somewhere.
I believe you must be on the T-Mobile ROM in order to get the Foreign SIM dialogue. Flash back to the T-Mobile ROM and try again, then flash back to your desired ROM once you're unlocked. Otherwise, you can use the OliNex SIM unlocker

I meant that you need to insert the SIM while your Rhodium is using the T-Mobile ROM, not to flash the T-Mobile ROM and then immediately flash to another ROM and try again. But anyway, here's a link to the unlocker, and instructions on how to obtain it from Olipro.

[Q] I have a Bell Galaxy S3 with Cyanogenmod, I'm hoping to unlock it.

Hiya,
I currently have a Samsung Galaxy S3 locked to Bell, and I have installed Cyanogenmod 11.
I'd like to unlock it and give it to a friend.
My questions are:
1. If I unlock this phone, will it work with Zoomer Mobile? It's a subsidiary of Rogers. I would imagine it would work, I just want to make sure.
2. I've read somewhere that Cyanogenmod causes problems with unlocking, is that true? Will I have to go back to stock firmware in order to unlock it, then go back to CM11?
3. I can't seem to find any information about unlocking through Cyanogenmod... anyone have a link to a guide of some sort?
Thanks in advance for any help!
am pretty sure you have to be on stock firmware to use free unlock method. will try to search around with for more info

Tell us the bootloader version on your phone.
Once unlocked, it will run on all carriers except wind and mobilicity.

Thanks, thats great to know! My bootloader version is I747MVLUEMK5.
Thanks for all the links mrrocketdog, looks like everything I need to start unlocking!
Since you are on the MK5 bootloader, you will have to flash back to stock, purchase an unlock code, unlock the phone, and flash back to your custom ROM.

Which version of stock, though? I can't remember what the phone came with since it was so long ago... I think it was something like 4.1 , but I'm not sure. Since I've since updated to 4.3/4.4, I'm also worried about bricking my device, because I've heard that flashing earlier roms with newer bootloaders can do that.
Which version of stock should I go with then? Thanks in advance!
Confirm that you have an i747m with mk5 bootloader and baseband. This can be done by using the Play app called Samsung Phone Info.
The stock i747m firmware is available on sammobile.com. Just search for the Bell sgh-i747m 4.3 ROM. You can flash it using Odin. Do NOT check anything except auto reboot and F.reset time. I recommend using Odin 3.07 and backing up your important data to your computer as flashing with Odin will wipe your phone.

Returning to stock rom from CM 12.1 to Android 4.2.2

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.

unlocking netword code wont work

I live in eu, i bought my m8 from t-mobile , i unlocked, i flashed custom roms, but its s-on , after 24months , i asked t-mobile for a unlocking key , but everytime when i want to enter that key, wont work, says wrong password.
Its posible that my mid/cid are messing someting with unlocking code ? Anyone got experience with similar problem? Should i flash some europian t-mobile stock rom to get solved this problem or?
And by the way is there a diference between us t-mobile and eu stock roms or they are the same ?
ps. i know some of those stuff are nubish for alot of guys. but i really want my network unlocked.
Thanx
Flash a stock ROM. If you are on an AOSP/CM ROM, it will do that to you. Stock ROM is the way to go to get your phone unlocked.

T-Mobile S8+: Need to go back to stock firmware in order to run Device Unlock?

So I have a SIM locked S8+, I flashed it to the unlock firmware to debloat, and to see if it will SIM unlock the device (it did not!). Now I have T-Mobile unlocked the device and received the typical email of "the device is unlocked, no unlock code, need to run Device Unlock App to unlock" email.
The issue is, with the unlocked version firmware, I cannot run the Device Unlock app, it simply says the app is not compatible with the device, which is right because you cannot unlock an already unlocked device, seeing that a device is running an unlocked version of the firmware.
Two questions:
1. Do I have to revert back to T-Mobile stock firmware in order to run the Device Unlock app?
2. If so, how to revert back? I have see this can be done for the S8, but have not seen instruction (files) for the S8+.
Thanks!
No one?

I have the same question too since I was contemplating on whether I should update my T-Mobile S8+ to the unlocked firmware but then I wondered if I could go back to stock T-Mobile firmware. Seems like no one has an answer for this yet : /
You can revert back 100%

If you flash T-Mobile Unlocked Firmware 955U1 yes you can revert back by just flashing T-Mobile Stock Firmware 955U. It was difficult to revert back before 955U1 was released where we flashed Canadian Unlocked XAC, but we finally got a solution as in the link below.
https://forum.xda-developers.com/showpost.php?p=72525783&postcount=5
Again, if you flash T-Mobile Unlocked 955U1, you just flash T-Mobile Stock 955U to revert back to stock. Note: You'll need to switch between unmodded Odin3 v3.12.7 and modded Odin PrinceComsy for Stock and Unlocked Firmwares. Another option which you don't need is reverting back using Smart Switch Emergency Software Recovery Initialization.
Warning!!! When reverting back there's 95% chances of getting a Phone Storage corrupt and the only option is resetting. Meaning you'll lose your data, so backing up your stuff is highly advised.
That option works great ?, just BACK UP and moved files to your SD CARD. I have done it more than 5 times, works great. I haven't UNLOCK MY S8+ yet, I'm getting another one so I'll UNLOCK it. YOU CAN CHECK OUT IMEIFIX.COM OR IMEIGURUS.COM . I have UNLOCK more than 4 S7 Edge, 2 Note4's and these guys work very fast. 100% recommended ?.
