[Q] how do unlock sites provide unlock codes? - HTC Jetstream

I've been google around for sake of knowledge and benefit, how does these unlocking sites provides unlock codes based on IMEI of devices?
most importantly do they have an inside man or there is actually a way to calculate things based on the carrier and IMEI provider which gets this number?
Thanks

i already unlocked my jetstream using one of these sites and paid them, my question was just how they make it, buying them from network provider seems fishy, i think they have other ways of generating them because they ask first if doable or not like they are testing something on the IMEI #

My guess would be that they pay the same type of people who crack software and create software keygens. The difference being they probably need to brick a few phones in the process.

*** XDAII Unlocking - NEW IDEA ***

Hi all
I have only just bought my XDA II but think its the muts nuts so no flames foir this newbie PLEASE
I have read many MANY threads concerening the unlocking of this new device and I just came up with an idea.
Since O2 seem to be, at best, inconsistent and, at worst, ANAL about unlocking, can we exploit the fact that they have at least released the unlock codes to a few people. I have two ideas
1) It seems that the Unlock code is IMEI deppendant so, Can someone who has been given a code publish it along with their IMEI number
then using the famous Manipulator software change the imei number in an XDA II then insert different network sim and enter the unlock code, I know this seems awfully simple but often the best ideas are. I guess you could always change the IMEI back to its original state if there were concerns about network security. I dunno what do you guys think???
2) What about if everyone who has managed to get a code publishes it to this site along with their IMEI number and then I'm sure one of the XDA Developers code reverse engineer the unlock codes and see how its related to the IMEI. I assume you could then write a KeyGen prog like people do for software keys (I mean so I heard, allegedly, Honest)
Failing that would it not be possible to write some program that acts like the modem terminal prog and just keeps entering random (or sequential codes) till the device unlocks
As I said its all new (GREEK) to me so no flames please, I'm just trying to help.
PS Anybody know about the Bluetooth issue with the XDA 2 and how to solve it and dooes it really work?
Thanks
Have you read this topic?

It's about xda2unlock --> and it unlocks your device!
Unlocking XDA2 and the bluetooth problem are all in the forum. By the way, messing with the imei number on a phone here in the UK can get a person jailed for 5 years and or a huge fine.

[Q] SIM unlock T-Mobile G2 Hero for free?

I cannot believe after all this time there is no code generator where you input your IMEI number to get an unlock code for free on the Hero after all this time.
I have a custom rom and need to unlock my phone so I can use it on the "3 Network" but I cannot find any instructions for sim unlocking on a custom rom for T-Mobile. All the guides seem to be Orange related or are quite confusing with counter instructions throughout their respective threads.
Anyone know of a code generator (the sites that sell the codes must be using generators) or know of a reputable place to get the code to work through a custom rom?
I don't want to get a code and then discover that the code won't work on a custom rom on T-Mobile.
Thanks.
T-Mobile G2 Cronos Froyo 1.7.3
You can call your operatior and ask them for the code. Most of the time they will give you one.
Thanks for your reply, unfortunately, they said that they will charge me £15 for a phone which I now have bought off of them because I am at the end of my contract. The gits.
Are there no free code generators?
Have you ever tried Codes to unlock your mobile. Do you know how perfectly codes unlock your mobile. You need to see the comments of many sites which provide free codes. All are negative comments telling the codes generated were wrong and their attempts were over trying them over and over again. So I advice you not to go for any sort of code generators. Majority of Unlock codes(except free codes) got from network providers or other third parties works like Gem. You wont believe i have been unlocking my mobile using codes successfully with this guy WickedUnlock for many years.

At&t won't unlock my Aria

I understand there are two ways to unlock your HTC aria.
One is to buy the unlock codes on some website.
The second, free way is to call AT&T after three months and they will unlock it for free.
However, I have called AT&T twice and they don't have the unlock code available even after giving them my IMEI number. I'm puzzled by this. Is anyone else having the same problem? They said the computer or database don't have the Aria unlock code in the system. What's going on here?
Big brother just tricked you. They are tracking you now. Throw the phone away. Use cash only. Don't use your real name.

AT&T doesn't have to give you the unlock code for the Aria until the exclusivity for that device has expired. Your only choice for now is to unlock it using a third party website.
Get the unlock code through a website like the most of us did, its just $15 or $20 bucks and they send you an email with the code almost instantly..

be sure to search ebay first. i found an unlock code for my backflip for only 2 dollars, the same for a few other phones I've had!
!
You know...I'd be interested to find out how these unlock codes are generated...seems like people are robbing people of their money when they are selling these things...it probably isn't the easiest thing in the world to figure the algorithm out (if that's how they do it) but i can only imagine that once you do figure it out, it's a short process thereafter to generate unlock codes for people based on whatever information they need...

there is software that does this. unfortunately i think they require a USB Dongle to run the s/w and it is expensive.... until the Russians crack it anyway. LOL
anyone suggest a reliable unlocking site?? there are so many scams out there taking money and not producing a usable code.
Most of the unlock website I found are reliable as far as give me money back when they can't get it. ATT and quite a few inexpensive website can't unlock my Aria. Some on top of refund, give me free unlock code for future. I end up found someone said "doing it manually". Took him 3 day and $25 later, he gave me the code.

rooting just gives you the "ultimate-true-genuine" etc rights to modify the phone the way you want it
to unlock the phone it's a different story. You will only need to unlock it if you're traveling outside the US
Or to switch to T-mobile.

Last sentence not quite correct; a clarification. You don't need to unlock if you travel outside the US. The Aria works just fine in other countries; you will incur additional costs as a result because you are roaming on foreign networks but AT&T has plans you can buy ahead of time and terminate when you get back home. Now the clarification part: if you do have an unlocked phone you can use a SIM card from other providers in other countries (which you will have to purchase or borrow from someone that lives there). Unlocking simply allows you to use another SIM cards, fore example, like Tmobile (a GSM network) in the US. If you don't unlock, your are limited to AT&T SIM cards. Unlocking is really not necessary unless you want to run on different networks in the US and outside the US.
Don't worry i will help you...You can get the Unlock code better from Online site,Basically network provider ask you to wait to get the code from them,they will give the code,it's available in Data base,So if you need Code immediately means you can get the unlock code from here www.Superunlockcodes.com and get the free unlocking instructions from here Mobileunlockguide.com and unlock it step by step.

I travel quite a lot through Europe and since AT&T's roaming charges are quite high, I had to unlock my Aria so that I can use local GSM carriers over there. I used www.cellunlocker.net last year. Their "regular" service for $4.99 was not able to produce the code for my Aria and they gave me a refund. I then purchased their "advanced" service for $19.99 and had the unlock code in 3 hours.
One more note about the benefit of unlocking: Once your phone is unlocked, it stays unlocked. So you need to purchase and use the unlock code only once.

What is this MSL code thing?

Have a rooted moto e 2015 on textnow. It is running dirty unicorns rom. Cut off the service for a while, and now i've got it back on again... Anyway, the activation process wanted me to open the android dialer, enter ##72786# and then it'd ask for this msl code and reboot. Nothing happened with that code, or the *#*#72786#*#* so... What is msl for, do i need it, etc? I tried searching several forums and google to see what to do, but i may have been too specific in my search terms, i don't know. Any help is appreciated.
MSL (Master Subsidy Lock)
A numeric code (password) that prevents a user from accessing certain technical settings of a phone. It is specifically designed to prevent a phone from being reprogrammed to work with a different carrier (service provider).
MSL is relevant only to certain types of phones, such as CDMA phones. Other types of phones may have a similar type of code that goes by a different name.
This is what is usually meant when a phone is referred to as "locked". There are also "unlocked" phones that can be reprogrammed to work with a different carrier.
The reason for this system is the way phones are often sold. Many phones are sold below cost, (at a loss to the carrier,) with the expectation that the money will be recouped in the cost of the monthly service plan. The up-front loss that is later recouped is called a Subsidy.
For this to work financially for the carrier, the user must not buy the phone and then use it with a different carrier. The MSL makes that nearly impossible.
Unlocked phones are ususally much more expensive than locked phones, because there is no subsidy to offset the cost.

Aha! No wonder the company was stressing the importance of a user performing this last, "essential" step, yet wouldn't say boo about what it was for. I've said this many times before, repeated to the point of near-absurdity, but I must say it one more time: I love this website. ?

How to find huawei bootloader unlock code (exploits/patterns)

Since Huawei stopped providing customers bootloader unlocking code, many of us try to find a way to get them. I also found some service that provide codes but it is too suspicious. Also some claims that those third party simply go to Huawei customers support and ask for the code. So I think it is time for us to discover some patterns or at least exploits. Share your ideas here guys!!
Here are my question.
Why there is no blue-force attack program to find the code? Is it because it is harmful for the device?
Also, do you think it is possible to discover some patterns if we share IMEI and its bootloader unlock code of old devices?
