This method has been sent to me by android235, I can not personally attest that it is working so please if you do that, make sure you have a backup or odin to reinstall your phone
After root, use a file explorer.
I use the ES File Explorer downloaded from the market:
- Launch it
- Goto "Settings> File Settings". Be sure that Show hidden files is checked
- Also be sure is checked "Settings > Root Explorer"
- In "Settings > Home directory" write "/" (without the quotes)
explore the "efs" folder in the root
- move the following files in a backup folder somewhere to your internal SD card (you will need them if you want to restore later to original phone setup) : .nv_core.bak, .nv_core.bak.md5, .nv_data.bak, .nv_data.bak.md5, nv_data.bin, nv_data.bin.md5. Moving them they will be deleted from the efs folder (that's ok).
Reboot.
Now you will have it unlocked but with the generic IMEI.
Peace out.

Any way to restore the IMEI afterwards? Or is the simlock check based on the IMEI?

I suppose the files you saved are to restore if needed, for the rest I don't know as like I said did NOT try myself
Nah. I meant whether it is possible to restore IMEI while still having unlock. If I restore the files, the lock should be back. (My glide is unlocked, but thats not the point)

I'd rather spend 25$ for an unlock key on Americanunlocker.com
(worked great for me)
In fact, I have tried to hack the nv_data.bin but seems that it is not the same as galaxy SII and galaxy S.
Although you will get unlocked (generic IMEI) when removed those files,
I highly recommand that you have to backup them in a very safe place. Otherwise if you encounter any problems, you have to sent back to AT&T / Rogers.

The method will work.. i had tested it earlier.. a generic imei will be assigned..
however some operators do not accept generic IMEI..

This method is perfect ! My phone accept the Free Mobile's SIM card and is recognized by Orange and Free Mobile's networks.
(It connects too on the two another french carriers when theses networks are too low, I don't know why and if the reason is the AT&T ROM or the unlock method. By the way, although I am connected I can't do anything.)
i don't like having a genric IMEI. will wait for anther method or just pay for an unlock key (when i get my device ofcurse )
What do you mean by generic IMEI? Is it all 0s? Does this mean that it will no longer be detected as a smartphone?
I just tried this method and it did work for me thank u
one Q is there any way to fix genric IMEI and keep unlock .
Edit: I restore my files from a back up and relock the phone ..went to ebay bought unlock code for about 8 dollars ..Done

I've done the same thing with another website -more expensive x-( (Fastgsm.com), although it worked.
The only problem though is that every now and then the phone asks me again for the network unlock code. This has forced me to carry a text message with the info on the phone. So far it has asked me 3 times the unlock code. Every time I input the same code received, every time it accepts it and gets unlocked. But I think this is strange, this is the first phone I had that this happens.

Captivate Glide (Rogers version I927R).
I'm very interested in this thread since i'm french, and about to buy a phone in the US to use it here, in France.
If i understand well, the trick for unlocking it by file deletion is a bad idea since generic IMEI are not too well accepted on french networks, and when you buy an unlock code, it keeps prompting you sometimes.
My other option is the myTouch 4G Slide, so i'd probably better go for it

Hi, my phone is arc s.
2 Months ago, my phone works fine with any simcard. Until i do the factory reset, then reboot.
After that my phone always shown EMERGENCY CALLS ONLY
I've tried to search for networks but only some networks detected and it's all in 2g network, no 3g network detected. And the worst is my carrier network was not detected even its 2g or 3g network.
Now i use another simcard from another carrier that detected on my phone. At least i can use my phone with only 2g network.
Anyone knows what is causing this?
PS: I've tried all stock rom, some custom rom, all CM rom. Unlock and relock bootloader. But no effect. Please help :crying:
And yes i've enabled 3g network selection in setting

Let's start out with the basics - Questions must be posted to Q&A, not General section.
Second, did you try to repair firmware by PC Companion? Use the method for when phone does not start up. Make sure bootloader is locked first.

I don't know whether here is place for it or not but i couldn't find any solution anywhere else. I bought my W nearly 1.5 years ago. Since one month earlier, everything has been fine. But then I received a message saying ''Your IMEI number is clonned, please contact with your firm.'' I went there and they said the very only solution is to bind IMEI to one phone number. This is very important for me because I use my phone for connecting net on my PC via USB Tethering and for this everytime I have to switch SIM Card. Now, I have two questions about this;
1) Is there any other legal option to do but bind the IMEI to just one stable phone?
2) If not or it's the only legal choice, what can I do to use another SIM on my phone?

Are you using Stock ROM/Firmware? Have you tried to Factory Reset your device?(Backup your files if you are planning to do so) If Factory Reset won't work, try re-Installing Stock Firmware.
I'm using LiquidSmooth v2.9, every other thing is stock. I tried changing ROM but i didn't work ( tried stock also)

Changing ROM either stock or custom won't change your IMEI. Some says you can change it using a program but I'm not sure though. In some country, changing it is illegal and punishable by law.

Yea, in my country it is illegal. But I don't want to change my IMEI, I just am asking whether there is a way to use another SIM Card when my phone's IMEI is stuck with only one stable phone number. But it seems now there is no way.

I'm a bit confused mate cause in my country we can always use different kinds of SIM Card, of course with our own country's communication networks (globe, smart, talk n text, touch mobile, sun, etc.) as long as our phone is not locked to a specific network but it can be unlock too both prepaid and post paid.
Hey, So, I realized I posted a forum about this with an "anonymous" account.. And sorry about that.
Anyways, My issue is, my darn phone will drop the network, and decides to connect to a rogers or telus Network Operator instead of Bell (or just completely dropping the network entirely). I did the unlock hack through the original baseband, then updated to cyanogen 12.1 and installed the I317MVLUDNF3 modem, Same issues. I just dealt with it but am wanting to try to fix this. I recently moved to Resurrection Remix 6.0.1 (which, by the by, is amazing) and its gotten better reception, but same darn issue.
So, How do i go along to fix this? Any way through xposed or root or WHATEVER cause this makes the phone really unreliable.

It could be that these custom ROMs need the latest bootloader and modem to function properly.

I'm downloading the mvludnf4 modem, and i have the latest bootloader from 4.4.2.. So, lets see if this modem fixes it..
Any other ideas?
If it seems to work properly on a stock rom, maybe flash back a completely stock rom, flash twrp, and then a custom rom?

Sorry for the late reply. I flashed the nf4 modem and reception is better.. Battery life sucks but oh well. I think this is a hardware issue.. I'm getting around -90 to -110dbm and 0-7 asu MAX. Maybe my antenna is busted?
Maybe try flashing back to a completely stock rom instead of just flashing the modem?

Well.. I don't see how the ROM could have an impact with the signal strength but I'll give it a try. Anywhere i can find a completely stock rom? The one stop shop only has stock slightly modded. Unless that will work

And maybe the dialer unlock causes this? I could try getting it properly unlocked? Any insight on how carrier locks work?
I had an i317m that was locked to Telus running stock kk.
I used Odin to flash a stock 4.1.1 Samsung rom, sim unlocked the phone via the dialler menu, flashed back to the latest kk, pass the phone to a relative, and he has been using it for years on Rogers with no signal issues afaik. It may be possible that this method of unlocking causes a signal issue but I can't be sure.
In the thread that was linked, it looks like it could be a hardware problem.
Hmm.. Well I tore the phone apart and the antennas seem to be jn place.. The 4g antenna is alot smaller then the GT n7100's. Maybe that has something to do with it.. That or this phone has trouble with bell frequencies?

Then i am completely lost.. Something must be hardware related.
Not 100% sure but doesn't the phones imei number have to be registered on the network it's using. Maybe imei has something to do with it.
Just a copy and paste off the internet instead of linking to a website. I think imei is the problem.
What is IMEI?
Mobile phones, except the serial number have also IMEI number. IMEI — International Mobile Equipment Identity. IMEI — a common standard for all mobile devices, which is assigned to the phone at the time of manufacture it in the factory. It's the unique number, which is broadcasting to the carrier to authorize phone in the network. Structure of the IMEI is the same for all phones regardless of manufacturer. IMEI number is also used to track and block lost or stolen phones by the carrier, which further prevents to use of such devices. However, blocking IMEI in one carrier network have no effect in others networks.

Well.. If it was an imei issue wouldnt it be getting no signal at all since the phone can't register on the network?
Canadian carriers don't need the imei to be registered, only the SIM card.

Contact your carrier or go in and tell them that it is not your number and that you are stuck on 2g they should be able to tell you how to fix it or if you go in they can fix it
I did contact my carrier, they cannot figure out what to do. Replaced the sim about 4 times, still no luck. I go into testing (secret code) and I am on 1x network @loeffler23
