[REF] Reset IMEI to factory default

[anonymous572]

If you want to return the original IMEI then you must do this before reading the manual.

You must have root on your device to continue this manual.

MOD EDIT: Removed

This manual does not show how to change IMEI!
It is only shows how to return the factory default IMEI on Samsung.



Tested and works on the following devices:
Samsung GT-I9000
Samsung GT-I9001
Samsung GT-I9003
Samsung GT-I9100
Samsung GT-I9103
Samsung GT-I9220
Samsung GT-N7000
Samsung GT-P1000
Samsung GT-P6200
Samsung GT-P6800
Samsung GT-P7500
Samsung GT-P7510

Is that YOUR IMEI #?

Is that YOUR IMEI #?

This is a factory default IMEI on Samsung GSM\3G module.

I thought every device has a specific IMEI

Better way would be to backup your /efs folder WITH the right permissions, then restore them back.

Anonymous, are you joking? because this is the better way to be blacklisted by your provider and samsung won't help you. ..

Provider can only block you number or IMEI. In my country IMEI 004999010640000 works fine on 2 big providers and there is no blacklist. In many European and Asian countries (like Russia and China) is no IMEI blacklist at all.

If you dont need to reset default IMEI just do not pay attention to this topic.

problem with saying "default IMEI" is that most would read that to mean the original that their phone came with. You should really amend your first post to warn that this will set some "generic" IMEI and may be illegal or at least invalid for use in countries where the carriers are may block an IMEI. This would be true for the UK and probably many other countries as there is a requirement for carriers to block handsets that are reported stolen.

As already mentioned, best to backup your /efs and save it onto your SD and PC so that it can be restored should you need it.

Oh dear, this makes absolutely no sense! The IMEI is the unique identifier of the phone, and it has to be unique in an network of a mobile phone operator! This means: As soon as more than one user follows your hint, the phones will not work any more!

The guide is a direct way to brick your phone! Don't use it!

So don't use it.

Who tell you this bullshit? Thousands of people in China, Russia, Belarus, Ukraine use the same IMEI like 135790246811220 (on some china phones) and did not block anyone so far.

Do you even read the red text in the beginning of the thread? Or you just need to speak out nonsense?

 

[geek78]

what is a non sense is to not explain on the 1st post to don't do that in the major countries (it is prohibited in most countries, this IMEI number is nothing in most countries, this IMEI number will be blacklisted in many countries, Samsung will refuse to honor the guarantee ...)

Yes, and thousands of people in China, Russia, Belarus, Ukraine are posting in threads like "Help! My IMEI is 135790246811220 and the phone does'nt work!". There is a special website only dealing with IMEI 135790246811220 and how to workaround the problem (BTW, the solution is: Throw away the phone).

Anyway: Why the hell should I go for a default IMEI?

You guys are being curbside techs.... listen this is a generic imei Samsung uses for all their radios and devices before they started doing indevidual imei for devices. It is not illegal it is your device do what you want with it. Leave it to the user to figure out their laws. When was the last time a imei was used to catch a fraudster? Cell tower triangulation is how we do it.

The debate is unnecessary because the method SIMPLY DOES NOT WORK. It may or may not work if certain further steps are performed (e.g. manipulation of md5 checksum and backup files). But the simple replacement of nv_data.bin does not change the IMEI. At least not on my phone.

Works for me and I'm sure thousands of others as well. It'd say logic dictates you sir are wrong.

@jason

And why does not work for me? I replaced the file (verified by checking the date). Following the reboot, the IMEI was the same. I think a md5 check failed and a backup was installed or something like that.

If you speak french : http://www.journaldunet.com/0305/030515phonesec.shtml

My last GS2 (a used one) was in fact stolen : blacklisted by IMEI ....

 

[RiverSource]

Ok, maybe its working or not or whatever ... it doesn't matter. Again:

Why the hell should I reset my IMEI?

Can anyone give an answer that makes sense?
