Hi everyone,
I have read up a lot on different people in similar situations to myself, but none of the solutions I have found have been successful. Anyway, here goes:
01) I rooted my GT-N7100 (Samsung Galaxy Note II) using Odin and then installed Cyanogenmod onto it.
02) I decided that I did not like CM, so I downloaded the stock rom for the handset and went through the process of putting the phone back to normal
03) This was successful, however, during the process my IMEI number has changed on the OS level, so that now the IMEI written on the device is different to the one that is displayed in the device status.
I am not trying to change my IMEI number to anything other than the number that it is supposed to be, I just want to be able to make calls and use my mobile data again. If anyone has any ideas about how I can go about editing the current IMEI number, I would be really appreciate it. I'm aware that this is a taboo subject due to the legality of changing the number, but all I want to do is get my phone back to the way it was.
Please feel free to ask me for any further information.
Thanks in advance.
I have a very weird problem with this device.
Recently bought one off another person. I tried to flash it but the flash code is wrong.
After reading that the flash code should not be wrong and derived from the imei, i realize it is highly possble that the imei on the back may not be the imei of the mobo itself. Would like to ask if anyone knows how to check the imei of the device via any software?
I have a Cricket branded galaxy s6 on the Cricket network and I was having some issues with the fingerprint reader which led to an eventual factory reset after trying many other things and of course I forgot to turn off reactivation lock beforehand. When booting back up I realized my Samsung account wouldn't sync up and I realized what I had done and after trying numerous things to fix that problem it led to me flashing the firmware for my phone and of course I didn't make a copy of the efs folder. So now my phone cannot connect to any network because the IMEI number is showing as unknown and so is the sim card status. So my question is... Is there anything I can do now to regain network connectivity?
If you are rooted you may restore nv_data.bak and nv_core.bak, that may get your IMEI back, if not, you can purchase a new and clean CERT file to get a new authentic IMEI back.
Would the phone have to have been rooted before deleting the IMEI number? I still have the original IMEI number written down as well
Greetings,
I would like to ask for anybody's help on fixing a dilemma that I can't seem to solve due to how limited my knowledge is.
Colleague messed up his phone very bad, he was trying to "Unlock" his phone through SamsungTool. Here's what happened;
1. Phone is carrier locked.
2. Read a guide that suggests that he should flash a "lower" baseband.
3. Flashed a lower modem file through Odin. Didn't backup EFS. But did take a photo of IMEI and S/N using *#06#.
4. Faced with DRK error. Phone is inaccessible.
5. Rooted the phone to remove DRK error.
6. Phone is now accessible. Used *#06#, IMEI is now 3500000000006, S/N is none.
7. Force flashed IMEI using Samsung Tool. Luckily, he took a photo of the *#06# details.
8. IMEI is now in place but MEID is different, S/N says "None"
Is there in anyway in fixing this?
Dear XDA members,
this is my first post, so please be a bit patient if I do something wrong
I got a very stubborn phone from some relative - he complained that sometimes the voice is fading during voice call. Otherwise the phone was working flawlessly, no other issues/trouble, was working across Europe. It was imported to Europe from Asia, which seems to have some importance, but we'll get there.
When I got it, the first thing I tried was OTA update - however there was some error (it still had 5.11 version back in December 2018). Not thinking too much (and not being aware about CSC codes) I got Odin and flashed it with 7.0 stock firmware. At first moment everything seemed fine, but after some time I inserted my SIM-card and I noticed that phone can't register to mobile network - then I tried another SIM-card from another carrier and result was the same. I tried to flash with few another ROMs with different CSC codes - but the result was exactly the same.
The IMEI and serial numbers reported by phone were in line with info on sticker and engraving on the back cover, but then I found that *#0011# shows IMEI Status: NG.
Wondering if the phone is not black listed I checked it's IMEI at imei.info web site and to my surprise it reported different Samsung serial number than the one on back sticker/cover! I opened back cover and I found that the phone has been manipulated, there's no sticker on the battery with phone info, but is some "Chinese" OK sticker...
I searched the XDA-forum and tried various fixes:
1) deleting nv_data from /efs partition in order to restore factory IMEI, etc., (https://forum.xda-developers.com/showpost.php?p=75927733&postcount=37),
2) flashing with combination firmware (https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-fix-check-drk-imei-issues-t3379516 tried both A and B methods),
3) downgrading to 5.1.1,
4) HEX editing efs partition backup to change Samsung serial number to the one reported by imei.info - I replaced sn in three places, phone reports "edited" sn, but I have no clue if it's not causing any checksum errors, I still have "original" backup,
5) repeating 1,2,3 with "new serial number",
6) installing NexusOS-9.
None of the above made it possible to connect to mobile network, checking with *#0011# after each of the above (except for NexusOS) still shows IMEI: NG
Is there any other way that could help that issue? What does IMEI: NG actually mean?
I checked with some phone repair shops, and none of them seemed to be equipped with Z3X-toolbox, at one place I heard that they can try to fix it, but give no guarantee of success, since the phone looks to be non-original.
As I wrote at the beginning - non-original or refurbished in Asia, the phone worked without any issues in few European countries, so I assume that IMEI is not black listed anywhere.
Thank you in advance for any guidance!
