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

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

Mytouch Slide on AT&T question

Hello all, I'm about to purchase a Mytouch Slide for use with AT&T, and wanted to make sure I wasn't going to have any issues with anything not working (GPS, SMS/MMS, etc.). I know I won't have AT&T 3G, only EDGE, but I can live with that. I searched but found very llittle on the subject, I'm assuming thats because both this handset, and this section of the forum, is fairly new.
Hopefully I'll be able to learn more about the handset in the next few weeks, and be abe to start helping others around here too. This appears to be a rather productive, professional forum. To that end, I'll say thanks in advance
What exactly are you asking.
So far the only people I know of, that can unlock this Phone is T-Mobile. Also, you must have an account in good standings & be a customer longer than 3 months..

What, really? So, I can't just buy one from, anywhere, and go use it? I'm new to this whole unlocking thing (CDMA background, and I work for a CDMA carrier), so I'm not really sure how the unlocking process even works. I guess that means I'd be much better served purchasing one that is already unlocked?
Well you can ask them lol but yah Check local listings new mytouch slides are only 300 and get them unlocked idk XD sorry

I'm sorry, I don't understand what your post says. The MyTouch Slide is significantly more than $300 new. It was posted above that they can't be unlocked. Are you stating that infact isn't true, and they can be?

unlocking works the say way it does for CDMA as it does with GSM. The only difference is instead of having to take my GSM phone to my carrier (or call them) to have my ESN number changed to my new unlocked phone like i would have to do with a CDMA phone. I can just pop my SIM card into my new unlocked GSM phone.
Even if you work for a CDMA carrier you should know that. If you work for any cell phone carrier you should know that

I understand the idea behind being able to take my sim card out of one GSM phone, and put it into another. The network looks for the info on your sim, not your ESN/MEID. And honestly, the only carriers that 'unlock' any CDMA phones currently are a couple of the pre-paids (MetroPCS & Cricket) as far as I know. You can't take a Verizon phone to Sprint, or visa versa. I work for a MetroPCS retailer, I know all about flashing CDMA phones to the MetroPCS network, and it's alot more than simply opening it up to be able to be used with anybody. Not to mention needing to use a 3rd-party flashing software that will flash Metro info to the device, as well as extract the MEID from the handset and add it to the MetroPCS database so the MetroPCS activation system will recognize it as a usable handset. So, it's really not a fair comparison.
Regardless, it still leaves my question unanswered. I've never dealt with GSM phones outside of simply buying a new one at the AT&T store. Being able to 'unlock' it to use with any carrier is a new idea to me. So, instead of everybody telling me I'm stupid and that I should know how it works, can ANYBODY point me in the direction of an explanation of what it takes to unlock a GSM phone, what changes need to be made, and why a MyTouch Slide is special WRT it not being able to be unlocked?

Might I ask how you got yours unlocked?
I got mine unlocked from theremoteunlocker.com
Gsm phones are locked via its hardware just like how when you use your pc the bios is software interlayed into your mobo so they could lock it if they wanted to only accept the types of processors they accept e.g tmobile locked their phone (the mobo) to only accept the tmobile simcard (the processor) the unlock code is a delevoper or admin unlock code that removes the simcard lock so you can use any simcard on it

Got it, I just figured that out from reading the website that you said you used. SIGNIFICANTLY easier task than 'unlocking' a CDMA handset. I've already sent them an email, if I can infact get one unlocked, I'll be buying one this week. Thanks!!

Look around on tmobiles website, the have the conditions for giving you a unlock code posted. If you meet the conditions they will email you the unlock code.
I did it with my slide, I called them Friday and they emailed me a unlock code by Monday. Free and easy.

I'm assuming by perfect you're not including 3G since the slide isn't set or rather, doesn't contain the correct radio module to use AT&T's 3G band. Or does it and we're being lied to by the carriers (no surprise there) hmm...

What the possibility of flashing an epic to work properly on vz? I see it can be done on cricket....I'm not worried about Verizon having the meid in the system....anyone out there do this? Thanks

Why is it you're not worried about Verizon having the MEID in their system? That is all you should be worried about. If it is not in their system, they will not allow the device on their network.
I can have it added.....so back to my original question.......can it be done??
I'm sure there's a way, you just won't have 4g. May need msl. Just use getprop to get it
Of course its Possible i have did for 2 Carriers in India why not Verizon, get your MEID added and be in touch be me.

If you can have it added then I think you're going to have to find out through trial and error, as not many have that kind of access. Let us know how it goes.

Verizon won't stop you from using a Sprint phone, but they won't help you, either. Assuming the software radio itself isn't the problem, you're basically going to have to wait until there are AOSP kernel and Android builds for both the Epic and Fascinate, then figure out how they differ and hack an Epic build to incorporate the changes in the Fascinate build. Then copy over Verizon's own apps for things like voicemail.
If you need a new radio, all bets are off. AFAIK, radio firmware signed with Verizon's key won't install on a phone expecting Sprint's cert, and vice-versa. Unlike Android itself, the radio firmware is very, very encryption-locked, because it's basically impossible to get a phone with software radio past the FCC if it's not (unless you're only planning to sell it to licensed ham radio operators, and have the means to enforce it). I'm not sure whether it was possible to reflash Sprint WinMo phones to work on Verizon because the radios used the same firmware, because the radio firmware was signed by HTC in both cases, or because someone found a way to defeat the protection.
You'll probably have better luck if you try to get 1xRTT working before EVDO. I believe there's a small difference between the way Sprint and Verizon's EVDO works (one that's entirely due to software and not insurmountable, but might be the reason why Sprint phones doing data roaming on Verizon seem to be limited to 1xRTT, assuming it's not just a business decision by Verizon and/or Sprint to allow Sprint users to only roam at 1xRTT.
Has anyone been able to solve this? I have my epic for sale or trade for a verizon phone with no offers... So I'm curious if I can just take it to verizon with me.. since its bad ass..
I fixed the data not working on an epic flashed to cricket by changing the msl to 000000 and dialing *228 so maybe try that. If you can manage to find a cool vzw tech rep get them to go into switch view in acss, go to the data section and uncheck the box that requires validated shared secret data for data use. I would help you myself but I no longer work there. Directv has better benefits I wish you the best of luck bro.

if someone has a phone active already, they can extract the shared secret and write it to the Epic.
No radio firmware or ROM will make it work or not work.
lots of sprint phones are active on PagePlus. They will activate almost any CDMA device. PagePlus is a vzw MVNO.
I've said enough.. any more might be breaking the rules
I'm tryin to figure out how to do the whole entire thing from the beginning.

It suddenly became against the rules to discuss using phones on different carriers? This is no different from discussing bringing a T-Mobile phone to AT&T and making things work -.- Sure there's no SIM card in this discussion and the technology is different, but that's it.
It is not against the rules. Only making a phone with a bad esn work is.
But this is a question and belongs in Q&A

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.

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.

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.

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.

Thanks for your reply. This phone has a sim slot. It's a GSM/CDMA hybrid. I've put in ATT sim card and when I power on, nothing shows up asking me for the unlock code. I can't find it in any of the settings menus. Does anyone know how to unlock this phone?

I would like to understand this too. What is the software that I need to change if I want to use a tmobile sim on this phone? Will it be the same process if I port to cricket (CDMA).
There is no HTC design forum or I would post this question there.

do I need to unlock phone first to unlock GSM?

[Q] Is this thing factory unlocked?!

This might seem like an odd question but I was poking around my note 4 today and i'm noticing something interesting within the settings. If you go into Settings> More Networks> Mobile Networks you can see a small list if mobile network options. If you select Network Mode, you can see it has GSM/UMTS as an option to select. Going back you can also see within that small list of network options a grayed out setting "Network Operators." This leads me to question, is this phone capable of being used on both GSM and CDMA? If not with factory Sprint settings, possibly something the hardware is able to do unlocked? I just find it interesting that the device offers different network options than the standard CDMA/LTE that I am used to only seeing on and once more there is no carrier branding on the device at all outside of the initial splash screen upon start-up.
What do you guys think?
Before my sprint note 4 was activated, in the apn settings,i was able to edit it as there was nothing in there. Once I had activated the phone it showed the sprint one and had became grayed out being uneditable.

Interesting, thanks for the share. During that brief moment you had in the APN Settings, did it display list of carriers or was it like an actual edit option for you to place input? Im curious to find out if this thing can actually run GSM network sims.
ask sprint for a sim unlock...and check

It was the actual option to edit it and there were no carriers listed.

So me being the sly little devil that i am, decided to check my apn's on my phone which turns out, THAT THEY ARE EDITABLE!!!!. So i can know assume that the phone may come factory unlocked and that we should add another carriers apns and sim card to try it out. I believe this is the reason why the phones dont have the carrier branding on them, because they are proprietary to samsung before activation, and then that carrier adds the signed/encrypted packages to the phone. So, with that said.... I NEVER ACTIVATED MY NOTE 4. i SWITCHED BACK TO MY NOTE 3 AFTER I PURCHASED THE PHONE. ( sorry for the caps, pure excitement) Then I skipped the activation and blocked the phones internet access, so here i sit with an non activated sprint note 4. If anyone wants me to test anything let me know!
Here are the pics.
I got this ...

yeah... but I do believe if you get an unactivated one and run the setup with another sim you could get it to work!

Any idea what I beed to do to save the apn. They wont atick. Should I acquire root?
i stuffed a tmobile sim in and got the invalid sim msg, if its anything like the s4 etc we will need to sim unlock it and then domestically unlock it.
you can always ##786# and enter your MSL to reset the device if you think sprints programming is the thing messing it up, however it really does wipe the device.
its a no go

I can see att and tmobile network, but i did some browsing in the build.prop file and discovered that there is a setting that says uses sprint sim card only. So It turns out that sprint used the same lock method as the note 3 on this. So now im trying some other things, going to look into a jtag and solder directly to the chip to read files and write them, so i can find out whats really going on with this unlock behind the scenes
sim locked
I'm stuck with my sprint galaxy note 4 unactivavted .
Did you guys ever get yours unlocked
if you are still with sprint .
One guy told me that i would have to get Sprint to do a international ulock and that will unlock the sim but the phone has to be active on sprint's network for them to do it
If their is a way to unlock my phone without going to sprint please tell me thanx and good luck

same here have this sprint n910p trying to unlock or use it with gsm slot any carrier how to go about it
I just hate sprint so bad, I have the nexus 6 witch I know I can take to a GSM carrier but we are wondering if my wife's Note 4 can do the same once we pay them off.
Currently the note is not sim unlocked in the US they are unlocked for outside the US. But with in time I'm sure some great xda member will find a way like they did on the note2

ask sprint to do a " international sim unlock" now because you are going overseas for vacation . they will not do it if you dont just to go to another carrier but thats what I found out after they do that then the phone can be used with another carrier. that is what I didn't do and now they said I would have to get their service two year contract and keep it for 3 months and then they will unlock sim pay early termination fee goodluck

Galaxy Tools has a SIM unlock button in it. I pressed it and it says Im unlocked now but not sure. So as far as sprint unlocking it for you I think its possible you can do it yourself for international.
