Today i’m making another tutorial.I hope it will be another “masterpiece” made by me, because i haven’t made any for a while.Most of people might ask, why is it exlusive tutorial.It’s because i’m writing this myself and from my own knowledge.There aren’t any tutorial on the network about it.

The tutorial is about changing the IMEI of a mobile phone.IMEI stands for International Mobile Equipment Identity.Every
phone has IMEI and every phone has it’s own unique one, just like IP’s.IMEI can’t be changed, but that’s what the goverment says.
IMEI is used to identify GSM, WCDMA, iDEN and also for some Satelite phones.There’s two kinds of IMEI’s, one of them are “Blacklisted” and other’s are inside of the Clean list.Some cheap phones what’s made cheaply, doesn’t contain correct IMEI chip and they don’t classify as a “Blacklisted” or Inside of the clean list.If GSM can’t verify the IMEI, you can’t call with the phone.
There’s two ways to make sure the IMEI.The first way is to write *#06# in the phone and the phone will give you the IMEI like this
The other way for finding the IMEI, is removing the battery.There’s writtened IMEI too.
Most of IMEI’s has 15 characters.Some of them has 17.They’re saying that every IMEI is unique, but actually it’s not.“New IMEIs can be programmed into stolen handsets and 10% of IMEIs are not unique.” According to a BT Cellnet spokesman quoted by the BBC
If you have read the last chapter, you noticed that i wrote about the “Blacklisted IMEI’s”.It means that if some mobile phone has been stoled and the owner of the phone is going to police, the IMEI will be blacklisted.If the IMEI is blacklisted, you can’t call with the phone and it’s worthless.Then the only way to use the phone is to change the IMEI.If someone is asking, why can’t people call with the phone if the IMEI is blacklisted, then the answer is simple : GSM doesn’t verify blacklisted IMEI’s.Also the IMEI can be tracked, but that’s another kind of process and police doesnt even use it to locate stolen phones.
You should be aware of the information below if you’re buying a mobile phone.There are many cases if person has bought a mobile phone, but the IMEI is blacklisted and you can’t call with the phone.Also people has bought the mobile phone and has met the seller.The victim has even called with the phone, but after few weeks, the IMEI appears to be blacklisted.That’s so because IMEI’s will be added to blacklist 6-8 weeks after the report.It’s because many phones aren’t stolen, but just lost and the owner might find it.
“Softwares to change IMEI”We have all met these hacking tools what are promising to hack facebook with a single click.We also know that these “Click & Hack” tools aren’t working, they’re just made to spread viruses.Changing the IMEI is also a interesting subject and ofcourse there are also these fake tools whicha are promising to change the IMEI with a single click.There’s also many videos in the YouTube and they really look real, but somehow they aren’t working.There are some ways to change the IMEI with software, but it works only with old mobile phones what we’re being in use in the 1990’s.Also changing the IMEI with software isn’t secure at all.It’s just like hacking with Proxy, you’ll be detected with it.It’s like comparying “What’s the safest way, hacking with proxy from your home, or with VPN from a cracked WiFi?”.
We all know that IMEI stands for International Mobile Equipment Identity, but there’s one thing still unclear.Many people are claiming that it’s possible to change the IMEI on Iphone with software, but some people are saying it’s not so.It would be possible to change the IMEI with programs if the IMEI would be Software based, but it’s not.IMEI is placed on the mobile as a chip.It’s a small black chip.For locating it, you have to remove the battery from the mobile phone, and then you have to remove the frame also.It should place on the back of the battery and infront of the SIM card.It doesn’t always place on the back of the battery, but mostly it does.This chip what we’re looking for is called RX12 chip.Also it’s the only one where’s writtened “RX12″, so it’s probably not hard to recognize it.Bright people has probably already understood, how the process is going to be, but i’ll explain it still.
In theory, changing the IMEI is the simpliest thing what we can imagine.The IMEI places on the phone as a chip, so it means we have to remove the chip and add another one.
1)Take your phone which has it’s IMEI blacklisted.
2)Make sure to write your blacklisted IMEI down before starting.You can find it by writing *#06# in the phone.Also it’s writtened at the frame behind the battey.
3)Get another phone to took a clean IMEI chip from.
4)Remove the battery and the frame, then remove the IMEI chip on both phones.
5)Now you should have two IMEI chips.The blacklisted one you can throw away and the clean one you should but back onto the device what was reported as stolen.
6)Turn on the Phone and check the new IMEI by typing *#06#.
Theory seems easy and the process actually is easy, but the biggest problem is to remove the blacklisted RX12 chip and add back the new one.This process can’t be explained by words, you have to see it with your own eye.Luckily we have cameras to record something and YouTube to upload the video.
Brief explanation :
Like we all know, the goverment is fighting against anonymity.It means they don’t like what are we doing.Mostly mobile service providers are saying that “IMEI is unique and can’t be changed” because people might start looking to change the IMEI.Ofcourse there are some mobile service providers who’re also admitting it can be changed on their offical page and are saying to be cautious about it.There’s not alot tutorials on the internet who’re teaching to change the IMEI because it’s against the law almost in every country in the world to change IMEI.These aren’t like most of the laws, goverments are pissed at it.If you live in the UK, you might be charged if you have tried to change the IMEI or you’re considering to do this.Also you can be charged in the UK if you own tools for changing the IMEI chip.In Latvia, you’ll get criminal offense, for the things i listed above.Probably some people aren’t beliving me, but here’s an quote from Wikipedia.
Quote:Many countries have acknowledged the use of the IMEI in reducing the effect of mobile phone theft. For example, in the United Kingdom, under the Mobile Telephones (Re-programming) Act, changing the IMEI of a phone, or possessing equipment that can change it, is considered an offence under some circumstance. Such an action can also be considered a criminal offence in Latvia.
IMEI blocking is not the only approach available for combating phone theft. For example, mobile operators in Singapore are not required by the regulator to implement phone blocking or tracing systems, IMEI-based or other. The regulator has expressed its doubts on the real effectiveness of this kind of system in the context of the mobile market in Singapore. Instead, mobile operators are encouraged to take measures such as the immediate suspension of service and the replacement of SIM cards in case of loss or theft.
There is a misunderstanding amongst some regulators that the existence of a formally-allocated IMEI number range for a GSM terminal implies that the terminal is approved or complies with regulatory requirements. This is not the case. The linkage between regulatory approval and IMEI allocation was removed in April 2000, with the introduction of the European R&TTE Directive. Since that date, IMEIs have been allocated by BABT (or one of several other regional administrators acting on behalf of the GSM Association) to legitimate GSM terminal manufacturers without the need to provide evidence of approval.
Quote:Operator code is a unique number assigned to every telecommunications operator in all countries of the world. Operator code consists of two parts: Mobile Network Code (MNC) and Mobile Country Code (MCC).
If you have read all the tutorial, you’ve probably already understood why you have to check the IMEI before purchasing a phone from a stranger, but i’ll still rewrite it because i’m sure that very few people has read all my text above.If you have read the tutorial, you should know that IMEI’s are getting blacklisted and will become useless.They will get blacklisted if the phone is reported as “Stolen”.For preventing that you have to make sure you’re not buying a bad phone.
- Check are the IMEI behind the battery and by writing *#06# the same?
- If you’re buying the phone, make sure to visit the mobile service provider.They’ll check the validation of IMEI for free.
- Use the site http:/imei.info and enter the IMEI in there.I tried and it worked for my phone.If you’re buying a Iphone, but the site shows that the IMEI belongs to Nokia 3310, you should be careful.
Quote from wikipedia :
Quote:“New IMEIs can be programmed into stolen handsets and 10% of IMEIs are not unique.” According to a BT Cellnet spokesman quoted by the BBC.
The IMEI (14 decimal digits plus a check digit) or IMEISV (16 digits) includes information on the origin, model, and serial number of the device. The structure of the IMEI/SV are specified in 3GPP TS 23.003. The model and origin comprise the initial 8-digit portion of the IMEI/SV, known as the Type Allocation Code (TAC). The remainder of the IMEI is manufacturer-defined, with a Luhn check digit at the end. For the IMEI format prior to 2003, the GSMA guideline was to have this Check Digit always transmitted to the network as zero. This guideline seems to have disappeared for the format valid from 2003 and onwards.
As of 2004, the format of the IMEI is AA-BBBBBB-CCCCCC-D, although it may not always be displayed this way. The IMEISV drops the Luhn check digit in favour of an additional two digits for the Software Version Number (SVN), making the format
Prior to 2002, the TAC was six digits long and was followed by a two-digit Final Assembly Code (FAC), which was a manufacturer-specific code indicating the location of the device’s construction. From January 1, 2003 until that April 1, 2004, the FAC for all phones was 00. After April 1, 2004, the Final Assembly Code ceased to exist and the Type Allocation Code increased to eight digits in length.
In any of the above cases, the first two digits of the TAC are the Reporting Body Identifier, which identifies the GSMA-approved group that allocated the TAC. The RBI numbers are allocated by the Global Decimal Administrator. IMEI numbers being decimal allows them to be distinguished from an MEID, which is hexadecimal and always has 0xA0 or larger as its first two digits.
For example, the old style IMEI code 35-209900-176148-1 or IMEISV code 35-209900-176148-23 tells us the following:
- TAC: 35-2099 – issued by the BABT (code 35) with the allocation number 2099
- FAC: 00 – indicating the phone was made during the transition period when FACs were being removed.
- SNR: 176148 – uniquely identifying a unit of this model
- CD: 1 so it is a GSM Phase 2 or higher
- SVN: 23 – The “software version number” identifying the revision of the software installed on the phone. 99 is reserved
By contrast, the new style IMEI code 49-015420-323751 has a 8-digit TAC of 49-015420.
The new CDMA Mobile Equipment Identifier (MEID) uses the same basic format as the IMEI.
Check digit computation
The last number of the IMEI is a check digit calculated using the Luhn algorithm.
According to the IMEI Allocation and Approval Guidelines:
The Check Digit shall be calculated according to Luhn formula (ISO/IEC 7812). (See GSM 02.16 / 3GPP 22.016). The Check Digit is a function of all other digits in the IMEI. The Software Version Number (SVN) of a mobile is not included in the calculation. The purpose of the Check Digit is to help guard against the possibility of incorrect entries to the CEIR and EIR equipment. The presentation of the Check Digit both electronically and in printed form on the label and packaging is very important. Logistics (using bar-code reader) and EIR/CEIR administration cannot use the Check Digit unless it is printed outside of the packaging, and on the ME IMEI/Type Accreditation label. The check digit is not transmitted over the radio interface, nor is it stored in the EIR database at any point. Therefore, all references to the last three or six digits of an IMEI refer to the actual IMEI number, to which the check digit does not belong.
The check digit is validated in three steps:
1)Starting from the right, double every other digit (e.g., 7 → 14).
2)Sum the digits (e.g., 14 → 1 + 4).
3)Check if the sum is divisible by 10.
Conversely, one can calculate the IMEI by choosing the check digit that would give a sum divisible by 10. For the example IMEI 49015420323751?,
To make the sum divisible by 10, we set ? = 8, so the IMEI is 490154203237518.
