Changing your ROM or Radio, the effect on your IMEI and Device ID. - Touch Pro, Fuze General

Hi there,
It is always a difficult consideration, "shall I start a new thread on this?". But, I thought it would be good to have this information available to everyone. Please don't discuss specific ROMs or Radios in this thread. Just discuss the effects flashing has on your IMEI and/or Device ID.
Being new to flashing the following question came up. What happens to your IMEI and "Device ID"... (not "Device Name") when you flash a new ROM on your mobile. I asked this question in a specific ROM thread and the answer was... "not sure".
This may be an important question to consider before flashing your ROM. Example, my (paid for) Route66 GPS software and maps only work with my specific "Device ID". This is not the same as your Device Name. This Device ID is unique to your mobile (quoting Route66 support team).
This Device ID can not be found on the sticker at the back of your mobile below the battery. So, it seems to be some hardware or software generated number. On my mobile it looks like the following:
9934xx27xx089013B
(The xxx-es are just replacements for some other numbers.)
My IMEI number looks like the following
358xxx010xx4859
(The xxx-es are just replacements for some other numbers.)
I learned that the IMEI number on the sticker may differ from the one stored in your phone. If you press *#06# on your phone your 'stored' IMEI will appear. In my case the following showed up:
358xxx010xx485901
Note the additional two numbers not found on your sticker. Flashing your ROM or Radio can have an effect on these last two numbers I understand. They are some kind of version indication. So if you need to keep the same "full" IMEI number for some software to run on your phone the following question needs to be asked:
How will flashing the ROM or Radio effect your IMEI number?
How can we change the IMEI back to the original number?
Back to Device ID
In addition there are several questions unanswered regarding the Device ID.
Where does it originates from?
Will the Device ID change when flashing a ROM or new Radio?
Can it be changed back?
Do you have any experience with this? What effect did it have on your software? Did you compare your IMEI and Device ID before and after flashing? Do you know how to change the numbers back? Write in this thread please! (again I am new to flashing and if some of this information is not correct please let us know)
Thanks,

Moved this out of Rom Development as it has nothing to do with that topic, and would caution users against posting their IMEI numbers on a public site. That being said, please feel free to discuss the effects to your heart's content.

Receive MMS, shows phone number, not name?

I know this may have been briefly covered before in Dutty's thread, but 300 pages are a bit more than I want to re-read. Also this issue is present in the official HTC 6.1 rom.
When I receive an MMS from someone, it will either start a conversation with their phone number (even though they are a contact), or it will take an existing conversation and convert the name back to the contact's phone number.
I thought I read there was a way to fix this by formatting the phone numbers a certain way in your contact list.
If someone could tell me how to fix this, it would be great. Also a program that changes the format of phone numbers in bulk would be great to, if that's really what I need to do.
Apologies if there is a thread like this somewhere.
I assume everyone going to the 6.1 update will have this issue. I would imagine a sticky would be quite useful for this, unless there isn't some other kind of 6.1 sticky on issues already.
-James
The ones in my addy book in this format +15555555555 show up with the name most of the time. Any other format they just show the number. It seems if i have no other messages from the sender, even formatted like above, they will just show the number. As of yet, I have found no easy way to fix it other than changing all my contacts.
As you have stated that there is a discussion about this in an existing thread you need to do into that thread and use the search function found next to "thread tools".
If you want to extract that info from the thread and either update the wiki or create a new "[SOLVED]" thread with it in the first post the whole community would be grateful.
Please don't create a new thread asking someone else to get the answer when you already know where it is.

Invalid Phone Numbers Problem [SOLVED]

Thought I'd post this issue since I've run into it since I got my new G1. Possibly if someone has a well read blog it's worth posting there for Google to index! There must be others who have this problem. Anyway..
I moved all my numbers across via my SIM card. It seems the SIM cropped all the pluses (+) from the front of all numbers with +447... in my contacts. (+44 is UK code).
Now, a +447.. number is valid, and a 07.. number is valid, but a 447.. number is NOT!!
This I did not know. Now I need to fix 100+ numbers in my contacts.
Further to this, and G1 specific:
In Messaging if I send a message to a 07.. number it goes in a new thread. The reply will always (I think) come back with +447.. as the prefix. This means it starts its own new thread! Annoying at best.
I would recommend everyone change their numbers to use the correct +blah.. country prefix.
Also, the Messaging app could be a bit cleverer with parsing number prefixes when it comes to threading up messages . Android dev team reading??
Anyone else had this problem? Any comments?

Where does "Model No" come from?

General question about WinMo: where does the "Model No" value that is shown in Device Info come from? Is it something that can be changed without having to get a chef to create a new ROM and without reflashing my device?
I am asking this because it seems that some software (e.g., Bing) checks this value and goes into a different mode if the value does match one it thinks it knows about. Perhaps there are other values that derive from this (browser agent string)?
moved to the right forum, please post in the correct forums.

Permission protected data spoofing on CM7

http://review.cyanogenmod.com/#change,5677
This is an interesting patch to the CM7 repository frameworks base. If you scroll down and expand the comments you can follow the guys arguments on justifying such feature. Basically from what I understand this would allow you to spoof personal data to apps which may or may not request it. From contacts to SD card contents as well as phone IMEI (International Mobile Equipment Identity) number.
It's not a committed change but I wanted to see what the community thinks of having such feature. Personally I see all the reasons why this would open up a can of warms. What do you think?
I think in some other implementation this could be really helpful to the paranoid (like myself). However, I also think that those that are against it have VERY valid points. The community needs MORE widespread acceptance, not less, and something like this could cause major problems with Google, Carriers, Developers....
Sent from a bird cage, with a swing!
Correct me if I am wrong, but the intention is to spoof necessary data that an app might request that it doesn't actually need and to help prevent app force closes that straight up permission blocking causes. Like pandora requiring to read contact data.
Setting aside the other ramifications for a second... This is actually a good idea. It gives us power to not have to accept (for example) Pandora being greedy bastards.
Now the other ramifications are indeed severe. But for example, Swype. Why the hell can't I just buy it on the market?
I think arguing over it is a moot point. This cat is already out of the bag. We can't stuff it back in. This functionality is coming. Maybe not on Cyanogen, but it will be here for the masses soon. The greedy bastards that are trying to milk the system had just better deal with it.
Wow this thread could not have popped up at a worse time , what with all the NexusSense 0.3 users having trouble with their IMEI's.
But having read through all the comments on the change, i see why the CM team do not want to implement it, obviously this kind of change would piss off devs and carriers and of course google.
Yes it is a good idea for us users, but for CM's image and survivability , id say not having it is a sacrifice we need to make
First of all:
Wrong section.
Second: They won't add it anyway.
Some developers cried about it and everything.

I figured this is about a development of Android ROM and posted in "Android Development" section. Forgive me if there was a better place to post it in.
This is also not marked as abandoned (as of this post) and still up for debate in the open section of Cyanogenmod Gerrit section.
For devices without an IMEI because they don't have a cellular radio, such as the Nook Color, some amount of this is valid and regarded as highly valuable. While I don't condone being able to haphazardly change or spoof your IMEI, I do believe that for devices that don't have an IMEI that some measure should be taken to create a device specific IMEI that will persist between different ROMs and ROM installations. Unfortunately with no IMEI support for devices like the Nook Color, there is no persistent ID that can be used. As developers continue to use the IMEI as a "device stable" ID, we need to come up with a way to support devices that don't have such an ID, and perhaps generate a non-colliding IMEI from a has of their login information, or some other identifying metric that will persist between different installations. The TAC could be created to identify the device type, and then the serial number could be generated based upon some information provided by the user.
In short, outright spoofing is probably a bad idea, but something needs to be done for devices that don't supply these sorts of IDs.

Hello,
The Galaxy S7 has multiple variants and builds. Normally when asking this kind of question, you should include the model of your device. That way anyone wanting to help you actually has the knowledge to be able to do so. Phones have different internal parts, memory space, and so on. You can find your model number by doing the following:
- slide down the notification bar, sometimes you may have to slide down twice depending on the device. Click the gear in the upper right hand corner. "Settings"
OR
- Access your app drawer or all apps section and find your "settings" section/app. Most of the time it will have a icon of a gear, or three lines that resemble on off switches. Older androids sometimes use just have three lines (as the settings icon)
- Find the section labeled "About Device / Device Info" its usually labeled something similar if not exactly. Open this section
(Galaxy phones usually have this section at the bottom of your "settings" section)
- Somewhere within this section, there will be a label that reads "Model" and that is your specific variant which is needed in device specific situations.
* Take Note of this for future reference. You might think okay ill remember that. But when you come to realize your devices model number may be XDA-2017T1 and you look for something pertaining your device. You will also find something like this:
XDA-2017
XDA-2017YP
XDA-2017YP2
XDA-2017T0
XDA-2017T2
XDA-2017T10
Assuming that you will continually update and/or customize your phone. You will probably just memorize this, along with other important information. Some important things you should include while researching is as follows (the top two are very important)
1. [Model Number] ex) XDA-2017T1
2. [Android Version] ex) 6.0.1 Marshmallow
3. [Baseband]
4. [Kernel]
5. [Chipset]
6. Is device "rooted?"
7. Is the bootloader unlocked?
8. GSM or CDMA. Older devices even use IDEN
Those are only some.
* I also want you to know that im not trying to lecture you, or give you a hard time. I am honestly trying to help you and in order to successfully help you I have to ensure that you know things, or mention things, that is important to do. So your device isnt broken, or you get information that is correct but incorrect for your specific device.
But back to the topic originally referenced.
Q) "Is the program Dr. Fone able to bypass the screen lock security measures on the Samsung Galaxy S7?"
A) Based on limited information that is device specific, and the current Supported Devices section from Dr Fones documentation
"No"
• Dr. Fone doesnt have the capabilty to bypass your screen lock. They will probably include the S7 within a period of time due to it being a main stream phone though.
• Remember this; locks can and will be broken. Just because a vulnerabilty hasnt been exposed or discovered doesnt mean that its 100% secure.
• Keep current with OTA updates, keep in tune with tech type news.
• Encryption is vast subject, but I can refer to it like the "invisible magical ink" That was popular in the 90's. The light that reveals the ink to the naked eye, is your password. The inabilty to see the ink normally without a specific tool, would be encryption. So if someone cracked your password, your encryption would also be disabled. I linked more information below, for you to read. I still dont fully understand encryption myself, nor do I believe or trust it.
I based this information assuming your device is the SM-G930. It is accurate as possible but not guaranteed. Do realize with the information I mentioned and with the question you asked. I was able to do a simple Google search and almost immediately found the answers. Try to figure things out before you ask in the future. You can repeat the process of not researching prior to posting but typically your post will die. If you get stuck and have put forth honest effort, the great people here at XDA will probably help out greatly. I hope I have helped you, and you now feel better about your concerns. please pay it foward.
If you feel ive helped or gave a honest attempt to help. Hit the thumbs up, that is the thanks button.

I'm sorry, I completely forgot to mention the model of my S7, it is the SM-G930F on Android 6.0.1 Marshmallow, thanks for answering me.
On the other hand, I'm disappointed that a commercial program can unlock a phone.
I hope that this way of circumventing the locking of smartphones will be solved, because malicious people could use it to unlock phones that do not belong to them ...
The only way to protect yourself from this program is to install an application that protects personal data.
Thank you again for answering!
Wondershare Dr. Fonefor unlooking thr screen.
Wondershare Dr. Fone is a powerful instrument to regain iPhone lost information, it can help scan and recover them from iTunes or iCloud copies in case you've got backup your iPhone into iTunes or iCloud, or it helps you regain contacts directly from the device. Besides it's harmonious with iPhone 5s/5c/4S/ / 4/3GS and it might recover 18 kinds of content such as pictures, videos, contacts, messages, notes, and phone log, voicemail, voice memos, calendars, reminders, etc.. :good:
I agree with you. A commercial program available for a few dollars can unlock a password protected phone. What is Android/ios waiting to solve this threat?
