Relocated from email discussion:
Hey, great tool[editorial: I think in reference to: http://code.google.com/p/cdmaworkshoptool/ ]. Would it be possible for me to get a copy of the most recent build? I'm looking into some things on the galaxy s3 because we lose the min and phone number on non-stock roms. -C
to C:
Most recent build is .2 which is public.. What exactly do you mean by lose? As in they must be reprogrammed after.a rom is flashed? Does the, normal version of dev term you have downloaded fail to write the number back?
3:39 PM (2 hours ago)
to me
It's a temporary problem with cm10. Development has been slow. It's lost on the first reboot and then mms doesn't work. In android, under status about it lists "My Phone Number" as unknown and Min as unknown. Just trying to see if I can write them while the OS is booted.
to C:
To write a mdn and min typically you would connect to the phone in diagnostic mode.. Send mode offline. Send spc. Then simply write mdn and min from the nam part of the interface.. There are typically three nv items which dev term writes for mdn, and min. Then, mode reset will reset and you can confirm if this wrote the nv item..
Did that answer any questions?
to C:
Having never tested a galaxy s iii I'm not sure if devterm should work... There is alot of chatter online about a program called ets, you might look.for that if devterm doesn't work. Please let me know if you are able to successfully write on the galaxy siii.
to me
We are able to write to it with qpst. I actually got the numbers back, but I'm not sure how. Now Im in the process of seeing if I can figure out how to replicate it. What is supposed to happen when you put it into reset mode? It doesn't work for me after that.
to C:
After mode reset the radio of the phone will literally reset.. Some phones this will actually turn off and on the whole phone.. Some will just show no.service temporarily... After mode reset.cdmadevterm will disconnect.from phone.. There are alot of variables, but typically if.qpst could write the phone devterm should also be able.. The mdn and min are really quite simply three nv items, I suspect the subsystem that normally stores this information is being overwritten or formatted by cyanogen...
if you have ever used cdma worksop or qxdm the mode offline and mode reset is functionally the.same..
to me
Thank you so much for going back and forth with me on this. I really appreciate it. The only major difference I noticed between an nv dump on stock and cm is that cm has a lock code for some reason. What is this ETS software you're referring to? CDMA workshop is a bit too expensive unfortunately.
Although I am not totally familiar with the tool it is linked on XDA in another section:
http://forum.xda-developers.com/showthread.php?t=1696621
I wonder if this might have something to do with the chipset not being qualcomm? On the other hand if you said it worked with qpst maybe they are somehow compatible?
The VIA tool probably won't work since we do have a qualcomm chipset. I still have not figured out how i managed to get it to work once but it came up with the unlock sim message I put in the code for my phone that I Found in nvram and then I tried the spc and a few other things and eventually hit dismiss. It said that it could not connect or something to that effect. Then I checked and it had my phone number as 000-000-xxxx which xxx was that unlock code. Then I restarted and I had the number again. I'm wondering if I somehow got the phone to let go of how its storing the phone number.
Hm. If it is qualcomm I would think that cdmaDevTerm should work... this is how one would normally write the mdn and min with devterm:
http://www.chromableedstudios.com/techninjutsu/howtowritemdnminwithcdmadevterm
Perhaps if this doesn't work you could include the response to the NV write from the LogQ tab to help understand the behavior? Maybe the rom is activating a different Nam profile or something?(I'm not sure if I even have a spot on the UI for that in devterm but a log might help understand)
(for logging purposes you may want to trying writing a fake phone number for privacy)
I guess my question also is: are you trying to figure out why the rom does this? or just a good way to fix it when it does?
I know this is an old thread. But spent so many days reading all those stuffs. Finally contacted samsung service centre and they says they can't repair my phone since its not manufactured in my country. Tried repairs like '' GSII repair'' and lots of other. Am not sure what I did. Deleted efs folder and copied, pasted. Nv files restarted. But of know use. When I tried inserting another network simcard(my friends) . The imei didn't change. But I was able to make phone calls and 3g. Bought a new sim of the same network. But I couldn't use it to make calls. It shows network not registered(like my previous carrier). The only thing I am able to do is I can use 3g. And I am typing from this same phone. Thank you for reading this..

If all you want is the original working condition you might be able to restore to stock.
Make sure to select the version for your device/region.

After looking at that you might try to flash a custom ROM, now that you can revert back
Use your recovery mode to make a backup of your current state before you do anything further.
If you have a terminal emulator do "reboot recovery", or find a menu.
Alternately there is a button-press sequence or this app here:
http://forum.xda-developers.com/showthread.php?t=1410569
Might use a backup app on the internal sdcard. Use odin/adb to push/pull files to from the phone and computer to keep the backup safe. Moving to the external (removable) sdcard is also good.
Since flashing Lollipop last night, in Settings > About > Status, the phone number is in-correct. It is displaying the phone number that was originally associated with that sim card, not the number I had ported over by Three UK.
The number displayed fine on 4.4!
Calls/txt/whatsapp still seems to work on my number, just curious as to why it would show the original number and not my current number? and can it be edited without root?

Erm...
The number shown in settings is physically written to the sim card. When you port your number, three cannot remotely change that. My three sim card, along with every other sim i've changed numbers on, I've had to change manually using a setting in a custom ROM.
If it showed correctly in KK, I don't see how this is possible.

I'm 99% sure it did, i'm sure I checked it when I finally got it ported over! Maybe I was wrong.

I'm confident its that 1% I've been answering this question since android 1.5
Yeah small world indeed
I've been wondering lately, is there any solution to make a lost/stolen phone really unusable even after flashing etc?
Yes i know a couple method about google dashboard or google email verification, but as a flashing junkies, i look at that method is easily crackable.
I've been wondering too, is there any tech to make the phone unusable via IMEI blocking (user requested)? Unusable means like maybe the phone will no longer getting SIM services even after switching to any SIM cards -or- better if it still locks the phone and showing user editable lockscreen info - both even after flashing/changing email (since IMEI will still intact even after flashing unless you format the EFS which will resut in blank IMEI = no SIM services).
Then the phone manufacture support it by making an imposible (or hardly possible) IMEI changes, it can do via software or dedicated IMEI chip hardware.
The point i'm trying to make is if there is a tech like that, it will surely making a higher chance of someone retruning an accidentaly found phone and wishing for a reward afterward rather than having a thought of flashing it then re-use/sell it. The cost of making a locked lost/stolen phone usable again should be high enough that people wont bother to do it.
Well i believe i'm not searching enough to found the answer, but i guess there isn't yet exist any techonlogy to make a lost/stolen phone barely/fully unusable even after changes via software/hardware. It's been almost 10 years since android cames up,
I think we should push this to google/phone manufacture.
It's just my opinion, let me hear what is your thought.
And i'm wishing too somebody get inspired and take an action (since i'm just a lazy guy)
PS: sorry if there is a grammar mistake.
Can do nothing with IMEI there are many easy ways to change IMEI number of android device ???
or is it equally secure to use the same sim card but a new different number.
On the same carrier

In general...
Carriers tie the Phone Number with the SIM card Number and the SIM Card Number is tied to a devices IMEI (aka Serial Number).
So if you have a phone number for a device, and then change the SIM Card, the device will not be able to use that phone number on a different SIM.
The only way to tie the phone number to a different SIM is for the carrier to port the phone number over to the new SIM.
This cannot be modified or bypassed on the device because their all tied in to the carriers system for the towers.
I hope that I had explained this okay via text...
Good Luck!

I DO NOT provide support via PM unless asked/requested by myself. PLEASE keep it in the threads where everyone can share.
Thank you. I was trying to figure out the following scenario.
Let's say I suspect some kind of remote tampering or location tracking without physical access to my phone.
Which one is more secure:
1. Change the phone number with the same carrier
2. Change the phone number and ask for a new sim card on the same carrier.
This is a European carrier.

There's one thing that you need to know: tracking your device is also possible when the IMEI number is known(and the IMEI can be changed also) so even when you switch the sim card and the device has location services or internet access it's quite easy to locate your device once it's been setup.
Actually one of these people has all the info from the phone box (IMEI, etc)
Are there other ways to track. Is it easy for anyone to track me with an app, etc. Is it equally easy to track an older non-smart phone.
I saw several time, errors with I think triangle with exclamation mark (I can't remember the exact words) that I have no access to network. This would stay briefly and then be removed. What are the implications of this.
If someone has my number, is it fairly easy for them to get the IMEI.
If they have the IMEI, does this allow them to track location or also get access to my data.
How can I protect myself.

How would these 2 situations be explained.
I am putting the regular (not smart) phone in the pocket. It turns on. It appears I called my own number. It's possible that I pressed dial but I felt I wasn't pressing any keys. It's an old phone with a square large button below the screen. The call log on the phone does show that a call was made to the same phone (calling my own number). would this be visible on the phone if it was done remotely (or would that even be possible: remotely causing a phone to call itself)
I am told by an older guy that someone called from my number and gave a different name than mine (I am asked if I use a different name). The phone was in my possession at all times and it's a smart phone.
I was testing google find my device. I am getting "can't reach device" with location ON on phone. Why would this happen?
On the other hand, I can "play a sound"

Hi, yeah seems like your device is high jacked by someone. There was a case like yours some month ago here on xda(don't remember the thread right now). You should wipe your device completely(within twrp format every partition.
Then install a aosp based rom.
Maybe this wipes the remote access too, but sadly I'm not sure cause the other guy did it he same but after this it was like before.
Which part makes you think it's hijacked?
not being able to find the device.? or something else (someone calling with the same number in the above post)
It did find the device after I moved it a little bit. It wasn't finding it when it was still.
Then it was not finding the device after I turned off location.
Is that how it works if someone is searching by using IMEI with an app. ie. if I turn off location then device cannot be located.
Which AOSP ROM?
In that case, if remote access wasn't wiped, what was the reason?
If someone has the IMEI, can they hijack repeatedly?

This makes me think someone hijacked your phone https://forum.xda-developers.com/ge...-change-sim-card-change-t3746592/post75146000
I don't know what device you have(you didn't wrote it) but try any non stock rom hence aosp based like LineageOS or ressurection remix for example and wipe your device before completely.
I don't know the root cause of this problem, I just remember me what was happening on the other member last year and maybe you are in the same situation.
If not, maybe there's help for you
It's an LG G3.
The link you posted leads to a ROM. Is it the correct link?

You should try. It's also possible to track you again if he has a duplicate sim(yeah, that's possible). But I don't think so.

Exactly: your story let me think your phone/sim is hijacked.
I thought you found the thread you were talking about here of someone from a few months ago.

There was no solution sadly :crying:
If a phone is hijacked, does that mean the attacker has access to all data, camera, mic, calls, etc. Can make calls from the number, etc. or just track location.
Would this be visible to the phone company?
Is there a solution.

With Trojans its all possible.
Did you already do what I wrote? Format the phone completely and install a aosp based rom? You didn't wrote what rom you're running and which apps... Maybe you have a app that's faulty

Further to previous comments By strongest
Yes, if hijacked (trojan installed ) then it's likely they can access anything they want, though it depends on Trojan installed.
As you got a phone call from someone who gave a different name your phone may have been cloned (possibly after malware infection or if someone has hadphysical access to it & copied imie etc). This is good in that your phone bill will show activity of the other phone & you can get help from your phone company. Your Google acc may show something too....
have you done the basics? Installed good anti virus, checked if rooted, checked if app showing in device administrators etc. Even if it comes back negative a port may have been opened & Trojan self deleted. Then you need to either try a firewall or check network traffic to identify unknown connections so probably easiest to just reflash full stock ROM or custom ( best as LineageOS will give you security updates every month ) ( make sure you backup your pic, files, contacts etc first )
They can only track your imei if they have access to the network infrastructure (as far as I know) assuming you have removed any Trojans, tracker, spy app etc and have clean install a ROM,
If you had a Trojan you should assume they have ALL your passwords, including your WiFi (maybe router admin too!) Change them all (use a password manager)
