[Q] how to unlock the Samsung Galaxy S 2 Epic 4G touch from Sprint

Hi! this is my first time posting on this forum.
I want to unlock my SGS2 Epic 4G Touch from Sprint but I can't seem to be able to do it.
I was able to root it and have Superuser access, I downloaded Chainfire's app from the Android Market and ran it, but it says the system couldn't find the unlock code.... don't really know how to move forward from there...
Also, this is the Gingerbread EL29... and doesn't have an IMEI but rather a MEID which makes it harder for me to find an app to unlock it...
Any help please?????

My friend "unlocked" please expound further on what you are trying to do. We dont have to unlock our phones. Now are you trying to get your MSL code?
Edit: Also everything you need to know about this phone is either in the wiki or a sticky on the development page.

I have it locked for Sprint use only, but I wanna be able to use another carrier... I'm not sure abotu what I need... I already rooted the phone, I know I need a code to be able to unlock it... but I'm unable to get it. for some reason

You want to use on some Mexican carrier ?

"Unlocking" is only for GSM phones with a "SIM". Since you have almost certainly opened the backplate of the device, did you see a SIM slot?
No?
Oh, yeah, that's because the Epic Touch is a CDMA device.
You cannot "unlock" the GSM telephony, if there is not one to begin with.
You should be looking for APN settings for your carrier and a way to input them.
And, do some research, because it doesn't seem that you are at a required level of knowledge, of the system you are messing with, to even be attempting it.

Is this carrier CDMA network or GSM network?

CDMA carrier

type of radios in the phone. One cannot be used on another.
Maybe tell us who the provider is you're hoping to switch to and someone else can maybe look it up.
If your provider is GSM and you bought a CDMA phone, you're seriously out of luck.

CDMA my friend quite simply it wont work. there is no sim card and nothing to unlock. trade it for the AT&T SGII or Tmobile branded SGII

There is no such thing as an unlock code for a CDMA device, unfortunately for you.
In the US, if you find a CDMA carrier that is willing to activate a CDMA phone that wasn't originally designed for their network, you would have to give them the phone's ESN number (found behind your battery). They would add it to their network, which would allow them to activate your phone on their network. They may also require your IMEI, which is the same thing as the MEID. You can get this from the same sticker, or dial *#06# on your keypad.
You will have to contact the carrier you intend to use the phone on and see if this is possible. I know somebody who did this when their work sent them to China for two years.

My Galaxy SPH-D710 was purchased in Michigan through Boost. I just moved to Maine where there is no boost, and U.S. Cellular unkindly rules. This project is on my level but I ran into an issue I hope to fix tonight after 5 days of code manipulation. Ok, so here's the story.
Obviously my phone will not connect to a carrier, and no service tower to make things harrier XD. So amongst the edits and flashing, I lost my MSL. Come to find out, here is why: U.S. Cellular accepted my device on their network. It was simple, just said it was an sch-r760, they put in my ESN/MEID Dex and viola, accepted. Ok, here's the kicker (not as nice of a kicker as is in my trunk if you catch my drift)... APNs are locked as you well know. The question is, where the crap did my MSL go? Boost was going to give it to me but since I've been out of service for months and I flashed with no tower near, ALLLLLL DATA ASSOCIATES WITH MY ACCT is just gone. Phone records, MSL, even device specs.
My question... when I get to a tower, I will have to activate back on Boost to get their system to issue me an MSL to then be able to add U.S. Cellular APN settings after receiving my unlock code... OR since its also ATT, and Boost and U.S. Cellular both use ATT towers to roam around here... Will I receive my U.S. Cel access? I have already Paid my U.S. Cell activation and monthly charges. I couldn't have paid if my phone wasnt accepted. Even US Cellular said this. I'm betting I get on Boost network, then have to diag MSL add APN since I cannot edit and stick without MSL. Oi... What I do know, is I will prevail, I never fail! When I do, I will write an impenetrable Tutorial and circulate it to U.S. Cellulars demise

i don't think its possible to unlock cdma,other than flashing to page plus,but the reason why gsm is so easy to unlock is because you insert a different network card into ur 3G sim card slot,and u type in your network code when it asks,,,,,cdma(phones that don't take sim cards) are flashed to that carrier firmware wised which means you would go through alot just to reflash to another carrier.try flash to pageplus,that will cost money,but dirt cheap as low as $7

At&t Sim Unlock Debacle

I need some help. At&t won't unlock the Sim claiming "exclusivity" although this device is released by every provider known to man. Anyways, the voodoo sim unlock app for the international S3 is not compatible yet for the At&t 747. What should I do? I need to use straight talk and would like to be able to use t mobiles network. Should I return it or wing it? Anyone been in this position before? Does anyone have any info on whether voodoo app developer can or is working on building an unlock app for US versions?

How long did it take for you to get your code? I just processed an order with them.

done, unlocked. now i need some t mobile hspa radio's to flash.

Hey when I enter the *# code to see if my ATT GS3 is locked I don't get that screen that pops up on the vid showing its locked. How can I tell the phone is locked to ATT?
Thanks

U check by putting a non att sim in. It will ask for unlock code. You dial *#06# to bring up your phones IMEI number not to check if its locked.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

Well there was a video on the website that had a *# code to show if your phone was locked, so I tried that and got nothing so maybe I need a dif SIM other than the ATT one

yea i think it only works on international one. doesnt work on mine either

Ummm... Straight Talk uses AT&T's network. You don't need to unlock the phone to use it with them.
Edit: you're using it with ST's T-Mo sim? Why?

root it, then go here. id stay away from direct patching, but it shouldnt harm by plugging it in, reading the nvram.bin and generating a code

I was wondering the same thing. I thought I read you could use either an Att phone or a TMO phone on straight talk with their sims. Also in the TMO GS2 threads there are people saying they didn't even need an unlock code to use the GS2 on straight talk. I've never used Att or TMO but I'm taking a close look at straight talk. In general is it true Att has better coverage than TMO? I know they are both better than Sprint.

Would be great, if the required nv_data.bin file was actually in efs like in the international version, i checked for the file in /efs and it doesnt exit.

Same here.

There's differences in coverage. T mobile more hspa speed 6-7 mb/s, at&t 2-4 mb/s. At&t has more coverage overall coverage tho.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

But the AT&T version can't run on T-Mobile's bands. Nobody even knows if it will eventually be able to, either. Until then, you're not even going to get 3G

Well,bought the unlock code from cellunlocker instead,well see how it goes.I want to use the att version on the Rogers network.

Got the unlock code works fine,now using the att cersion on rogers's 4G network !

Thanks for the info on the two networks. I am thinking about waiting for the next GSM unlocked Nexus phone and running that on a prepaid plan that uses TMO or ATT's network. Hopefully we'll see one before the holidays.

note not recognized on network

Hey guys
Im in a bit of a pickle, I have been running the tmobile note 2 on simple mobile since it came out with no problems at all. After I did the update for the multiple window, the device does not connect to the simple/tmobile network. The device is unlocked and running all stock. I have tried almost everything, my sim card does work on other phones and other networks sims work on the note perfectly, I have done a factory reset, I even sent the phone to Samsung with no luck they say that everything was ok during their testing, but its not. I read somewhere that turning on and off the airplane mode for a while until it locked in with the network but nothing. I do have the correct apn settings, but still says that I cant connect to the network "not authorized"
Any ideas?

I would contact simple mobile or goto tmobile store and explain the situation. Maybe they will swap the sim card

i tried different sim cards from simple with no luck
do you think flahing the stock 4.1 of the note woul solve this?

Where did you get the phone? It sounds like it could possibly be imei blocked. Call t-mobile, tell them you want to check to see if the imei is blocked, give them the imei from the settings menu. If it's blocked and you didn't buy the phone brand new, you might be screwed.
If it's not blocked, try other suggestions from this thread. Gl man

If he's on simple mobile most likely he bought it from CL and got boned.

Nope, I got it on eBay as soon as it came out.

Sorry lol thank you by accident lol. My response is simple call ask tmobile why your not getting connection if that doesnt explain it then you have no choice to say your phone is a defect. If you hsve insurance make a claim. Or try use the same sim on another note 2 phone.
Sent from my SGH-T889 using xda app-developers app

Can you swap in someone else's (working) sim that is tmo/simple? If that does not work, that might point toward the imei blocked theory.
sent from my phabulous phablet using xda premium

The easiest way to test the imei theory is to call TMobile and tell them you have a phone you want to make sure is not imei blocked. Might take a couple calls to get a rep that knows what you're talking about. Try to get to technical support if you can.
Getting a TMobile phone from anywhere other than a TMobile store is now a crap shoot with their imei blocking policies. I understand the theory of why they do it, but it sure seems like there could be a better solution. At the very least, one should be able to pay to have it unblocked.

Did you try going to Settings> More Settings> Mobile Networks> Network Operators> Avaliable Networks> Default Setup> Manual & Choose T-Mobile/Simple Mobile Network?

Imei blocked for sure. Someone bought it, threw it on eBay and then didn't pay their bills. That's what happens.

[Q] Unlock code (sent from T-Mobile) does not work

To anyone who doesn't mind helping out,
I purchased a T-Mobile T-889 Samsung Galaxy Note II (4.1.2 Jellybean out of the box) brand new. I've had the phone for 47 days (I bought the phone on 4-9-13). T-Mobile made me wait 40 days (maintaining active account status) before sending me an unlock code. The unlock code they sent me was "07319707"
I did exactly as stated and the message keeps coming up "Network Unlock Unsuccessful". I've called T-Mobile 3 times since I received the code and all they do is escalate the problem to someone else but no one has e-mailed or called me back since. They told me if I try to enter it more than once that it might cause a problem which was after I had tried several times to do it.
I am fully aware of ppl buying unlock codes online and that if you have 4.1.2 that you must go back to 4.1.1 in order for the old code to work but I'm trying to avoid that.
If anyone has any suggestions / advice I would truly be grateful.
I am attaching a screenshot of the email from T-Mobile.
Thank You

I think the best option here is to work with t-mobile support and get it resolved.
I have always found the online chat support much more helpful than their phone support, give it a shot and hopefully this will get resolved.:thumbup:

Phone can be unlocked with an inactive sim. Just make sure you are using non t-mobile sim.
If the phone accepts the unlock code then it's unlocked but it wont show network on an inactive sim.

*status update* I spoke with T-Mobile today. They are emailing me another code...should be in my inbox by tomorrow. They also said that Wi-Fi must be turned off. I don't remember if I did that or not so that might have been an issue.
*GT-N7100*
For anyone reading this that has a GT-N7100 International Note II (my first one) who lives in South Florida (Palm Beach / Broward Counties) I found out today that I threw my money out of the window when I bought the T-Mobile Note II. Either T-Mobile is done or almost finished re-farming the 1900 MHz band down here and I was able to use my T-Mobile sim in the GT-N7100 that I own and able to average about 10mbps download on T-Mobile's network (4 more than AT&T). Around early April I tried using a T-Mobile sim (changed the settings properly) in the n7100 and couldn't even get 1 mbps download. I did not believe T-Mobile would go through with the re-farming in south florida because believe it or not we are not a top 10 market. For those of you who have an unlocked AT&T branded Note II who is still on AT&T... I strongly suggest you either try straight talk or T-Mobile itself and try to use the phone on T-Mobiles network...(Do you really need LTE when it's possible to get 14 to 15 mbps download w/o it?) For what AT&T charges for their service they are straight up ripping people off.

[Q] Just got an S3 model I747M but wont make calls

Im new to this phone
So the original carrier is Claro PR. I have succesfully unlocked the phone cause im using AT&T SIM on it and it has signal and all but it wont make/recieve calls, nor text and wont go on the internet.
Anyone have had this happen before on unlocked phone? I was thinking on rootinh it and throwing a AT&T rom to see if it fixes it but im asking first before trying anything that can brick it

Did you unlock it using the free method or by a code?
For data, did you check the APN settings? Under network preferences, did you select auto? Are you sure the SIM is registered on the network?

I'm at a loss as to why it doesn't work even though it gets a signal. Maybe something is screwed up in the service menu settings.
