Hi everyone. I've got a question. So my friend has a Droid 2 Global purchased with a bad ESN. Is it possible to change this? Would it be a matter of changing the ESN number? And what exactly is the difference between ESN, IMEI, and MEID? They all uniquely identify the phone, correct?
And if it is not possible to change the ESN or whatever needs to be done, can the device be unlocked to work on AT&T, T-Mobile, or Sprint?
Thanks.

ESN is the “old style” MEID. When you're talking about “bad ESN” that's effectively “bad MEID”.
IMEI is a GSM phone's unique ID, MEID is it's CDMA counterpart; MEIDs are only blacklisted by a single carrier while with IMEI, carriers (or even governments) can have agreements established to prevent cellphone theft.
There are no really affordable ways to change the MEID of a D2G.
To use a D2G with AT&T and T-Mobile you have to:
1. Unlock it via an unlock code (normally provided by VZW Global Services if the phone is active on an account in good standing for the last 6 months). The codes are sold on eBay (and specialised websites) and are a hit&miss kind of thing. If a code bought off eBay didn't work, don't bother buying from another seller. They're the same.
2. Perform a band unlock. AT&T and T-Mobile GSM networks are blacklisted in the baseband of D2G. Team Black Hat does a band unlock for a $100 fee; you have to mail the phone to them for the procedure, and you will be unable to update the firmware; it has to stay at 2.4.29 for the band unlock to work. Custom ROMs are ok, though.
As far as I remember, it's definitely possible to flash the D2G to use Cricket. Sprint, I'm not sure since I don't know which exact CDMA revision Sprint Nextel uses.
able chance ESN bad to good
1. root the phone(look on http://www.xda-developers.com for tutorials)
2. Flash a custom rom
3. connect the phone to any WiFi internet connection so you have access
4. Download an app on the app market called "MSL READER" this is the code you need in order to edit your settings.
5. go to the dial pad like your about to make a call and hit "##3282#" then click edit settings and enter the MSL NUMBER the app gave you
6. Well now you need to look for further details HINT: YOU MUST HAVE AND THIS IS REQUIRED... QPST TOOLS OR CDMA WORKSHOP TO CHANGE THE ESN/DEC NUMBER.. Use Port 7 or 28 to connect. You need to find a good ESN to replace the Bad one. Two ways to do it. You can look on ebay at phones like the one your want to activate and find a seller who has posted the ESN. Get that ESN and use it to replace your Bad one. Keep in mind who ever ends up with the phone on ebay will get the message, "Sorry, the phone you are trying to activate is active on another line." There is nothing he can do about it. You activated it first. If you have moral issues with theese directions that always work here is another way you can try. I have had success doing this with LG, SAMSUNG and Motorola phones. Simply change the last digit of the ESN number and only the last digit. Example: A000001769214F8 = BAD ESN Change to A000001769214F6 = Even for even Odd for Odd numbers. Works.
however, i don't know how to unlock ... anyone else can unlock it pls show me how to do that ... thanks

I do a lot of HTC device hacking and unlocking, but have never done a CDMA device. Is it possible to unlock the XV6700 and use it on another USA CDMA Carrier? Also, I presume there are other ROM's to install on this device? Any guidance would help a lot.

CDMA devices aren't actually locked per se, the device itself will work great with any CDMA network u tell it to work with as long as the service provider agrees to register your device in their ESN database. In other words all phones released by verizon have ESNs specific to verizon and all sprint phones have ESNs from sprint's database. The providers share the ESN data and know when a phone you're trying to register with them is not one of theirs. So it really comes down to your service provider agreeing to register your phone in their database (which is most likely not going to happen unless you have connections). The other and not so legal way of doing this is to clone the ESN of your old phone (which you can just throw away) and download a new prl (preffered roaming list: tells the phone which towers to prioritize) to your new phone. So it IS possible but illegal due to the ability to copy somebody's esn and charge up their bill. Hope this helps!
this might not be for cricket but its a start

Yes, CDMA Devices aren't locked like GSM Devices. You will need to have Cricket register the ESN (Electronic Serial Number) in their database. I have family who has done it and have worked with a guy who got a 6700 ESN changed over to Cricket.
Need to go from Cricket BACK to Verizon
I have the opposite problem - bought a used VX6700 that is already on the Cricket network, but I am on a Verizon plan (yes I was a doofuss and get my old Verizon phone wet, but it was locked LG crap anyway with no option for customizing - so GLAD to be coming back to the HTC world!)
Whenever I dial *228 to get it programmed, it says "welcome to Cricket". The Verizon 800# tech people had no clue how to get it back, even after they had me try a few unusual settings in the phone. Then they sent me to the Verizon store - they said they could not do anything, no real explanation why not. The used store I bought it from thinks they could try to reflash it - but I'm not so sure that is really necessary.
I have successfully flashed my old HTC Wizard for practice - so I know sort of what I am doing if flashing IS needed. Just hard to find information even after doing a lot of searching. There are a few threads on going from Verizon to Cricket -- but none for how to get BACK.
Thanks in advance.
Update
The phone guru guy at the Phone Smart store I bought the used phone from was able to get it back onto Verizon for me. He said something about modifying the PRN Provide Roaming Number - or at least I think that was the one - so that Verizon's towers would know to look for this phone now. So all good for now. I need to get WM6 on it soon though! Currently it is on a slightly enhanced build of WM5.
So I've done a large amount of searching, not only on XDA but elsewhere to find a real 'answer' to my question, but I haven't found anything concrete, hence this thread.
I have aquired a Droid 2 Global from VZW for free, and I want to use it with my US ATT SIM, on the US ATT GSM Network.
Things i have done:
- Flashed the phone to the stock OS in order to....
- Flash the radio so it accepts ATT GSM signal
- Aquired the sim unlock code from ATT for my current phone/sim (I'm unclear on exactly what this whole sim unlock process is about, perhaps why I'm asking)
The phone boots, but when I have my SIM inserted, it asks for the unlock code.... What exactly IS it asking for?
The SIM unlock that I recieved from ATT doesn't work.. (I assume this is the unlock for my sim, in my current phone?)
What is the next step, if this is possible? I've looked at getting the phone unlock code via ebay, or one of the piggyback devices like TurboSIM, but I'm unsure what will work, if anything will work?
Help??
Thanks in advance for any info provided
It asks for the unlock code you can get from VZW's Global Support if you are a VZW customer.

Well, since I'm at ATT customer, how would I go about getting this code? I do have a friend that works for VZW, which is how i got the phone, and he is willing to assist me. Can he provide it?
The phone must be on an active line of service, and the billing history must be clean for the past 6 months.
If your friend works for Global Support, then maybe. If not, I doubt it.
Hmph..
I guess I overestimated the difficulty of getting this to work. It was just another case of having to get the unlock code from the phone itself via IMEI number,and yahtzee, working as I had hoped.
For some reason I had the notion that it was significantly more difficult after reading all of the posts about trying to get other SIMs to work.. but its actually very very straight forward and easy.. it just seemed that nobody had ever really made it clear that a US ATT sim could work on a VZW D2G handset with US ATT service.
Thanks for your input!
I was just pre-ordering my Galaxy S3 on VZW and decided to skim the contract. I noticed in one paragraph that they have in writing what code the S3 is defaulted to for SIM unlock and use on another carrier. Now, I am wondering if AT&T was just as kind and put it in our One X contracts? If anyone has theirs handy, or a digital version, check it out. The paragraph in VZW contract said it was defaulted to either "000000" or "123456". I tried generic codes on my One X to no avail, and obviously don't have my SGS3 to test if they were telling the truth! Let me know if you guys find anything!
First of all, you will likely have to call Verizon to get the network unlock code in order for roaming. Unlock code usually is tied to the IMEI number of your phone for GSM phones. Secondly, even if you unlocked your Verizon global phone, you will still not be able to use on AT&T or T-Mobile. You can only use it abroad.
Now, it is possible for newer global phones from Verizon be unlocked use a default code but you will still not be able to use them on other US GSM carriers.
On AT&T, not only you have to ask for the unlock code specfic to your phone, but also AT&T won't give it to you until the new phone is on the martket for 10-month, the so called 'exclusive' period.

First of all, you are absolutely WRONG because I have a Rezound that works perfectly fine on AT&T without any unlock code, secondly I asked if anyone had seen this on their contract, so you can take your irrelevant post and shove it up your a$$.

Well this thread went nowhere fast. Most people wont know your answer. You're either going to have to call AT&T or just wait to see if its unlocked already.
Today I went to unlock my Sprint LG G Flex 2 after paying it off. Sprint gave me a code (In a form of ##xxxxxx#) to put in via the dialer, but it did not unlock the phone. They are telling me to go to a 3rd party company to unlock it, but I am wondering what you guys think. I know there is quite a few software loopholes that some people have used on the G3 to unlock it, and I am wondering if any exist with the G Flex 2. Heres whats going on
With a Sprint sim the phone stays on Sprint and works no problem
With a Verizon sim it will use the Verizon voice network but it does not get data
With an ATT Sim it goes between "Service Disabled" and 4 bars, but will not make a call or send a text.
With a MetroPCS sim it will not call, text, and stays at service disabled
With a PTel sim it stays at service disabled
From what it looks like to me the phone is not GSM unlocked. Is there any way I can unlock it for GSM use. I know some bands wont be picked up, but I would like to use it on ATT 3G when im out in the countryside where Sprint doesn't have service. From what I know of since the Feb. 11 revision of laws for unlocking devices if the device is in good standing and paid off/contract expired the carrier is supposed to unlock it, but there method is not working for GSM use. I am wondering if anyone knows a way to get there code to work or a software loophole to unlock the SIM slot for GSM use. I am guessing that the phone is receiving att and Metro service because the split second before it goes to service disabled it gets 4 bars and the phone recognizes my phone number. My ATT and Metro APN settings are programmed in already in the roaming area, but there is not an APN settings input in the mobile networks category.
If anyone knows how and if this phone can be unlocked to work with GSM service it would be a great help.
Thanks
Jake
Also, when I use the the Available GSM networks feature under "Roaming>Avalable GSM networks" it always comes up wit "Error searching for networks"
The phone is rooted, could I use unlocking methods from the G3? How much of a risk would I be taking by using methods sourced from another LG phone? To expand upon that I would attempt using methods proven with the g3 or original g flex to try and get it to start running on gsm, I did submit a domestic and international unlock to sprint but all they gave me was a useless MSL code. I need to get this working on at&t or I will have to sell this wonderful phone.
As far as I know they will only unlock it for a Sprint customer who has the line active for 90 days. Unless something is different on the Flex 2 there is no code to enter, I unlocked my HTC One M8 before swapping to the Flex 2 and everything was done on there end. Additionally they state the unlock is only for international use and will not unlock the phone for US carriers although I cant verify if that is true as I don't have a US SIM card to try.

The phone is fully paid off, it was used for less than a month. In the USA there is a law that was passed on February 11th 2015 stating that all carriers must be able to unlock there phones for domestic service (DSU) as far as I know sprint does not seem to follow that, and makes it dang hard to do anything. I was able to get texts working, and data, but I cannot call or receive mms, anyone have any ideas on why that might be. I would like to try and get both working, and I will put in the work for going into the root and trying to get the bands unlocked for AT&T, if anyone can confirm that it is not a gigantic threat to the phone by attempting it, I would make a backup before, but my last experience with a Verizon S3 + Easy unlocker bricked my phone, and although I got it recovered it was no fun.
Rooted...
You stated that the phone is rooted, was the phone rooted when you attempted the unlock? If so, I would suggest restoring the phone to fully stock via the files supplied by Malxce and method described in cairui505's thread here:
http://forum.xda-developers.com/g-flex2/help/ls996-tot-t3094660
I have used it and it works great. After that I would attempt the unlock as Sprint suggested and follow any further problems with Sprint tier 2 technical support. I'm sorry, I don't have the number handy but I'm sure Google will assist. Tier 2 support has a great deal more knowledge and capability than the store or tier 1 personnel. You are correct that they are required by law to unlock the phone at the users request but they will not make it easy and unlocking the phone doesn't change it's hardware capabilities. I'm just not sure if there is an underlying and limiting hardware difference between the carriers versions that would prevent proper activation on another carrier. The law requires that they unlock the unit, not include the hardware to port to other networks.
How would the phone being rooted stop it from being unlocked? I ask because I bought a used phone from ebay that's already internationally unlocked, I've been given the msl code multiple times by tech support, and as I've just discovered it's been rooted.
With my Bday money I purchased a A32 5g off of FBM for $140, bought a month of service, got the t-mobile sim delivered and popped it in and it did not work, called T-mobile and some foreign speaking sale associate who could not comprehend anything other then her preset phrases told me the phone imei was "blocked" even though the look ups say it is clean. Well I have no idea what to do about this other then to stalk the guy who insta blocked me after I asked him to unlock the IMEI, and was wondering if you guys would be able to help with my options. Also wondering if it may just be network locked? which I couldnt figure out which carrier it would of been used by, it did have the tmobile app installed tho. IDK..
Wouldnt mind doing roots or what ever to get it running, just not sure which direction to go.
An IMEI - what is comparable to a chassis number - can't get locked / unlocked

So that crosses out my thoughts of it being a sub branch like metro or something and network locked to only metro then?
