if i change the rom to an i-mate jasjar or any other will it be unblocked?
No
why is that ?
I'm not an expert but Sometimes I wonder why is that, If we replace ech and every file of locked mda-pro with unlocked jasjar ?? then there should be no reason for a locked mda-pro.
can anyone explain inside science of locking & unlocking ?
I think it also depends on the definition of "blocked"
If the phone iteslf has had its IMEI blocked, then no amount of reprogramming/reflashing will unblock it.
If the phone has a simlock on it, then I believe this would be to do with something within the phone hardware itself.
Hi guys
That old chestnut again, locked and blocked are 2 completely different issues and unfortunately neither of these actually involves anything that is didrectly under the control of pocket windows.
There are 2 types of locking.
1) PUK locking (SIM Locking), this occurs if you incorrectly enter the SIM pin code 3 times in a row. If this happens you need to contact the network provider to get PUK unlock code, better still if you enter the PUK code incorrectly 5 times you will destroy the sim and need t get a new one.
2) Network Locking is a flag that specifies the LAIN of the mobile network that supplied the mobile phone and if this feature is enabled by the operator it will mean that only a SIM card that has the corect LAIN will work in that phone. I forget what LAIN stands for but basically it is used in the GSM international roaming world and therefore each operator has its own, the first few digits indciate the country then the last ones the specific network.
This can be disabled in 2 ways firstly by using and encrypted code specifically issued for your handset. Or secondly by trial and error by writing different values to the registers on the EPROM on the GSM unit itself. Eventually this will result in the phone unlocking itself. In order to do this the gsm engine needs to be removed from the handest and interfaced to a serial port. A 0 or a 1 is then sent to each register 1 ata time and the phone is then tested to see if it works. Depending on the size of the chip this takes a long time. However when you no the memeory location of the register this can then be done to any phone in a matter of minutes. this is basically the way modsyt of the unlocking systems are developed.
Finally IMEI blocking. This is done where the network has evidence that a crime has taken place either fraud commited on the handest, abusive phone calls or the unit has been stolen. If the network IMEI blocks it you have 2 options, 1 sell it in a diferent country ( Nigeria) or some chip sets contain the IMEI details on a flash chip. Again the registers are read over a serial interface and this can be rewritten. The first phones to support this IMEI in flash were the siemens TC35 gsm engines also the wavecom gsm modules support this. I am not really sure of any legitimate application for changing the IMEI of a mobile handest or even why this data is not writen in ROM but there you go.
I hope that helps to clear up issues relating to locking and blocking.

thanks for such informative essay, we all are concerned about the network locking. I have noticed a tool to remove simlock from HTC wizard using same OS as HTC Universal. but in the above post its mentioned that OS has nothing to do with unlocking ..
But unloking tool of all old HTC devices running WM 2003 never took so long as in the case of Universal ? or may be quite possible that all good brains of our forum dont use Universal ?
1). Imei of device is difference when i check by *#06#... Why?
2). Sometimes i got "NO GSM" but sometimes i got "GSM" on tri-color... Better solution plz..
Plz Help! SOrry English not so Good... My hermes still function, juz signal sumtime enable/disable periodically.. ( Maybe difference device IMEI with actual IMEI.. juz thinking.. )

Your imei would be different if you have had the device repaired and main board replaced. I had mine done. If you have had the device since new and no repair then that would be strange indeed.
Not sure what you mean about the No GSM but having it on tricolour (bootloader) ??
yeah,someone can change the imei sn to all the numbers he wants via some software now.But, stickly speaking,all mobile phones are assigned a unique 15 digit IMEI code upon production. Below you can check all known information regarding manufacturer, model type, and country of approval of a handset.
Tip! The IMEI can be displayed on most mobile handsets by dialling *#06#. Otherwise check the compliance plate under the battery.

Hey everyone
Just a little confusion as I am trying to register my nexus with Walmart warranty service
They are asking for a serial number and a model number
Is the serial number the number that starts with c90 or is it the number found on the settings, status, and then serial number?
Also what is the model number and where on earth can I find it?
Thanks
Sent from my Nexus 7 using xda app-developers app
A model number is the same for all devices of a particular product line. For instance, all Nexus 7 models would have the same model # that identifies them as nexus 7 models. A serial number is specific to just one device only. It may have similar numbers or letters, but the last digits are often sequential and unique. No two device should ever have the same serial number just like no two mobile phones ever have the same IMEI. A serial number not only identifies a specific device and can be used to identify the owner when registered, it can also identify the time, date, batch, revision history and location of manufacture, things that can be very important in the event of a recall or defective product. My N7 has a sticker on the back bottom with the serial # on it. It should also be on the original packaging.
Hello,
I come to you because I have a concern is I need help is Board.

Sorry to hear that mate,
If you had an S3 mini imei means that someone for some reason changed your imei , most likely your phone is stolen......take it back , report that person......
Changing Imei is ilegal ..you will not get that help here in XDA
I heard that it was possible that from time to time there may have mobile device with the same imei since many mobile device in the world. how I can find my imei because my camera tell me ' meid '
IMEI numbers are unique and have several identifiers within them, along with a check digit to ensure they are valid. However, IMEI numbers can be easily cloned. According to a BBC News report on phone theft from 2002, some 10% of all IMEI numbers "are not unique", or in other words, cloned.[1]
What disturbs me more is that the device is not even displaying an IMEI number, but a MEID number. The I9505 is a GSM phone and would not have a MEID number. That means someone entered the service menu and tried converting this phone to work with CDMA, not realizing the phone doesn't support CDMA.
I agree with @MAX 404. Return the phone and report the person who sold it to you.
[1] http://news.bbc.co.uk/2/hi/uk_news/1749215.stm
The problem is that I have the box with imei above even behind the camera is even evidence that the same IMEI number corresponds to another device but not by s4 against the bill I find it is more it do more 6 months I buy this device. I can give all the evidence if it is necessary for its
Ok, so if I understand you correctly, the IMEI on the phone and the IMEI on the box match? To be honest, that doesn't mean much since labels are easily forged. But regardless, you're apparently not able to return the phone as it's out of its return window. I would bring it to a Samsung service center and have them look at it as we're not going to be able to help you here.
yes it's on I'll try to have a peekaboo samsung France to see if I can return it free
yes I have the same IMEI on the box behind the telephone + + in the phone I have to solve this problem of 'meid'
Well, as I mentioned upthread, someone entered the service menu and changed service from GSM to CDMA. I accidentally changed the service myself on my phone, but I went back in and changed the service back to GSM. Just don't ask me how I did it because I can't remember. Once I got my S4 working correctly after replacing the SIM tray and blowing away the SIM lock I stopped messing around in the service menu.
If you're adventurous, you can enter the service menu and try to change things back. I believe it's under CDMA services in the main menu. However, I believe the service center might be better, as it is possible to screw up things even further.
ok I have to succeed my imei number is returned
I count !!!!
Now my problem remains of imei, I have all the evidence that I possess much the device that has the right imei
exclaims the back of the device, on the box, paper proving that another device has the same imei but in s3 mini declare I believe and I have a 9505
edit:
I had to go into the service mode via * # 0011 # and then modify the CDMA option thank you to you Strephon Alkhalikoi
So, I see previous thread have been blocked. This IS about a stolen phone, but not about stealing a phone....
My son had an S10+ stolen, and the insurance are not paying up.
He believes he has identified the phone on sale... saying it is unlocked and operational.
Assuming the phone provider DID block the original IMEI...
Questions:
Is it even possible to change the IMEI?
If it has been changed, and labels removed, can the phone be identified subsequently?
Can the 'new' IMEI be traced (i.e. is it a GUID, or is there a list of valid IMEI codes somewhere?)?
Is there a 'block' of IMEI assigned to Samsung? - i.e. if it now has a random one, can a random one be identified as fraudulent?
If it's a clone IMEI, can you go from IMEI to original phone model?
Grateful for any advice,
Simon
Hi mate
Tough situation....
To your questions:
Is it even possible to change the IMEI?
Yes , there are ways to do it but you need special equipment
If it has been changed, and labels removed, can the phone be identified subsequently?
Depends on how good this people are, that information is in the efs partition you need equipment and somebody who knows how to check it
Can the 'new' IMEI be traced (i.e. is it a GUID, or is there a list of valid IMEI codes somewhere?)?
Yes , there are pages like this (there are others), place the imei of the suspected phone there , usually you will get back information as if is blacklisted or to what phone model has been assigned to , usually when the imei is replaced this people uses imei´s from old phones
Is there a 'block' of IMEI assigned to Samsung? - i.e. if it now has a random one, can a random one be identified as fraudulent?
See above reply
If it's a clone IMEI, can you go from IMEI to original phone model?
Not sure what you mean but I think the above reply should answer your question. Each Imei is unique and is assigned to a particular phone , if you check an IMei it will tell that belongs to a Samsung S10 for example
If you have the IMEI of the suspected phone it will be easy to find out if it has been tamper with it, to find out the original IMEI may be another matter
---------- Post added at 04:54 PM ---------- Previous post was at 04:35 PM ----------
With the page I gave you if you introduce your son´s phone imei it will give you the Samsung serial number of the phone, that may be something that they may have not changed, if you can get your hands on the suspected phone check Settings /about phone there it will show you the Samsung serial number.......

Hi, the imei and serial number is printed on the back of the device at the bottom.
Your welcome
Sounds very fishy. You can call carrier and report it stolen. Yes, if you claim u purchased the phone, u should have the original box with the imei printed on it
