[Q] Please help: IMEI lost on samsung galaxy note 2 GT-N7100

After a batter outage, it lost its IMEI. (after type, *#06#, imei is null/null). A crossed circle stands in the place of signal bar. Can not may phone call any more.
The phone is rooted once. But it work perfectly after rooting until last batter outage. Is there any way to get it back? I searched the forum and no thread talk about it (QPST doesn't work for note 2).
Flash new 4.1.2 firmware , won't fix the problem.
Even after tried "Factory reset", the problem won't go away either.
Please help with this.

Check to make sure you have not damaged your Sim card or the contacts that "read" the Sim card.

If you have EFS backup, restore it.
otherwise it is really tough

If it was a TMobile Note2, imei is easily fixed. I just did one yesterday. The N7100 doesn't seem to have the correct diagnostic modem. The boxes get around this by serial port and UART cable. Call some of the local independent cell phone shops and ask if they can do it. I know the NSpro box can do it. Last I looked the Z3X box could not do a N7100 but I have not checked their forums in several weeks. If you were in the Los Angeles or Central Coast area, I could help you out.

What is a good on device efs backup tool. I've been using EFSpro on the desktop. TeamWin recovery backs up the EFS. I tried HKTools but it said it did not recognize the phone.

Twrp supports it.
In backup menu tick just efs.
Never tried it though.

welcome

Hello, y'all. I don't know that I'll get a reply any time soon, as this thread is over a year old, but I am having the same "ID: bad key" problem on my Moto G5S Plus (XT1806) and I have no idea what to do, being that I have not ever even unlocked the bootloader on a phone, as I am having this problem with a phone I bought from eBay that had this issue when I received it.
The full message that displays on my phone is this: "Your device has been unlocked and can't be trusted. - To learn more, visit: motorola.com/unlockbootloader - ID: bad key - Your device will boot in 5 seconds."
For the record, I'm not really concerned with this message being displayed after I restart the phone, as the message goes away after about 5 seconds and the phone starts up properly and is able to be used (*for the most part, with two issues, which I will describe below this paragraph*), it's that the phone will not see any Android updates and is still stuck on these outdated settings: Android version: 7.1.1 - Current version: NPSS26.116-61-8 - Security patch level: April 1, 2018. And I have tried to search for updates with my T-Mobile SIM card in the phone, and also when connected to my home WiFi, but it will not see a new update available.
* The two issues that I referred to earlier have to do with actually making calls on the phone, with outgoing calls taking like 20-30 seconds to actually start dialing and incoming calls not even ringing through to my phone and sending callers straight to voicemail (the phone shows no notification of someone having tried to call me). Text messaging works properly, and I am able to connect to a strong LTE signal with my T-Mobile SIM card in the phone and I can use apps and websites without any issues. However, outgoing calls take much longer to dial out than they should take, and incoming calls will not work at all.
So, I am hoping that flashing a different ROM on to the phone will fix these calling issues and also allow the phone to update to a more recent Android version. However, as I mentioned, I have not ever even unlocked a bootloader, much less, actually flashed a ROM on a phone, so I have no idea what I'm doing when it comes to things this. Also, for the record, I have tried multiple different APN settings on this phone, I have used my T-Mobile SIM card in another phone without any calling issues, and I have done multiple Factory Resets, but nothing has fixed the calling issues or allowed the phone to see any Android updates.
By the way, if flashing a different ROM might be worth trying on this device, being that I would be a first timer doing something like this, how difficult would this be? And about how long should the process likely take?
If anyone has any helpful advice, information or suggestions that they could offer me that might help to fix this issue with my Moto G5S Plus, I would appreciate any and all help that I could get!

If anyone sees this thread and is willing to offer a reply that might help me try to fix this issue with my Moto G5S Plus, I would really appreciate some help with this!

This message means the boot loader is unlocked. Honestly not a huge deal. If you do not plan on using TWRP or Root at all, search the forums on how to relock your boot loader. Otherwise if you wish to use a different recovery or root looks up the logofix which is easy to do. It will have the moto screen, but will say say bad key in small white letters. More thank likely the previous owner had unlocked the boot loader and then flashed it to factory stock before giving it back. That doesn't relock the boot loader so it gives that warning.

Please Help: No Signal / "service state: out of service" [With Screenshots]

I would be so grateful if someone more knowledgeable than I helps me troubleshoot this issue.
I bought a used Nexus 5x yesterday, everything worked fine and it was all stock, i checked my sim card and it worked on the phone.
I took it home unlocked the phone and installed a custom ROM, somehow In the process I seem to have done something that has made it so the phone cannot connect to my mobile network. It seems to be able to see the mobile network [ imgur.com/IdpFg0O ] but not connect [ imgur.com/5edM5G6 ]. The phones APN setting [ imgur.com/5J1Ixoy ] appear to match the information provided on various websites.
The SIM status page [ imgur.com/WGWnqSM ] might give some indication as to what the problem is. It lists the network as "unknown" and the service state as "out of service" and mobile network state as "disconnected."
What I have already tried:
Restarted the phone

Wiped Phone (factory reset)
Reflashed the same custom ROM
Reflashed another custom ROM
Reflashed the Stock ROM
Could I have maybe somehow screwed up the /EFS partition when I was wiping or installing the new ROM?
I dont really know what else to do to troubleshoot or try to fix the problem. I would be sooo sooo grateful if anyone more knowledgeable than I am could help me troubleshoot this issue, there doesn't seem to be much information out there about this problem. I really don't want to have bricked my phone the day after I bought it, so please, if you can offer any assistance helping me understand and diagnose the problem, I would be so grateful!

All rooms require a specific version of radio.img make sure you have the right one otherwise you'll have problems like that check out in the xda thread of your rom what version it requires and then download the factory image and flash the radio.img with fastboot

Hi kastik4,
Thanks for the reply, I appreciate you taking the time to lend a little help.
So if I understand you correctly what you are saying is that each specific ROM has its own radio.img and that a mismatch could potentially be causing my problem?
If so, I'm not sure if this is the problem as one of the troubleshootings steps i've taken is trying to go back to the stock factory ROM following Googles instructions and (I believe) flashing the stock radio.img. However, it is entirely possible that I did something incorrectly in this process so I think I will try to redo the process and make sure I got everything right tomorrow.
Any other ideas as to what could be the issue?

@local5x: you wrote, that you reflashed stock ROM. If you did it via flashall.bat (means you lost /data and root) and error persists, probably your hardware is gone.
Messed efs you can detect easily: IMEI shown in settings and on your contract, must be identical.
Generally is the newest radio-image fine. @kastik4's advice is mostly overdressed.

Hey, did you solve your issue or you still need some help?

No, I did not solve the problem. I got a cheap phone in the meantime, but haven't been able to figure anything out with the 5x. Maybe it is a hardware issue, IDK, and I dont really know where else to go in terms of troubleshooting, I'm sorta in over my head here. I wish I could narrow down the problem though, even If it is just to find out that it is a hardware problem and I'm screwed at least I would have a little clarity/closure.

hello I have the same problem my phone says no service and only emergency calls, I followed some solutions nothing yet. I would like to find a solution since it does not detect the available networks

PLZ !!!HELP!!! me to unBrick my Samsung A705YN

Hi
Long story short, I purchased this phone privately from a random person on internet. Used it for about 2 weeks than 2 days ago phone got locked remotely by a rental company ( Using MDM/Knox). I called the rental company and found out the seller illegally sold a rental phone to me. Anyways i went on removing that lock by rooting the phone and followed instructions on this XDA forum to instal TWRP beta. First step of flashing VBMETA went well and than i flashed TWRP using odin and after a blue screen pops up showing Security Error: this phone has been flashed with unauthorised software ................ Odin not allowing me to flash official stock firmware on it . All error screenshots are attached. I can still get into download mode but not in recovery.
PLEASE help.

Install the latest software update if the software you are using is a lower version that the phone will not accept

Hi Mady,
I have your same problem, how did you solve this issue? can you perhaps share the step breakdown? I would greatly appreciate it, since I'm facing the same issue. I also bought a phone from the internet and the guy had taken it leased from somewhere else.

Hi,
I was researching through XDA, and this solution is the one that best seems to suit my problem. I can't install any firmware because I get the message : MDM Mode: Can't download (PIT)". in your recommendation you are saying to install Australia firmware. How can I get past MDM issue? with Odin? my bootloader is locked, and I cant access the main menu to enable developer mode and toggle the OEM unlock feature. is there a way this can be done through ADB or some alternative? thanks in advance for your help!

Mi 9 SE bricked after successful MIUI 11 Update

Hello everybody!
I have a problem with my Xiaomi Mi 9 SE. This is what happened:
Few days ago I updated to MIUI 11. Everything seemed to run smoothly.
2 days ago I noticed a huge battery drain during the day. I finished my day with my battery @ 10/1% with my usual daily use.
Yesterday I was using my phone normally while it was charging (watching a video on Youtube). The phone became unresponsive to everything: the touchscreen was not working, the buttons on the right were not working.
I decided to "hard-reboot" my phone. I pressed the on/off button for a few seconds.
The screen turned off.
From this point on, my phone was completely bricked. It does not turn on in any way possible: I tried also pressing the on/off button + volume up or down but nothing. Nothing happens even connecting it again to the power cord.
I tried connecting my phone to the PC via USB and this is what my PC recognized:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
But my phone still remains bricked/with its screen black.
Has anyone else experienced this problem? Do you have any suggestions on how to fix this or at least recover my data in some way?
I suspect some bug related to battery mgmt in the MIUI 11 and I personally do not suggest you to update to it right now.
Thank you very much in advance!

You're on edl mode. I've been there. Unfortunately, Xiaomi doesn't allow us to recover our phones on edl mode, which is a shame. So, there are two options:
1 - Send it to the seller and try a fix/replacement.
2 - Pay someone with edl authorization to unbrick your phone.
If you want, I'll give you the contact of the person who did that for me. But I had unlocked the bootloader and flashed several ROMS. I bricked the phone trying to restore a full backup. Your case is different and, for what you described, you may be experiencing hardware problems, so I would go for option one.

Thank you very much for your reply! I really feel disappointed because I never messed up with my phone. I always used official releases. Since I bought it in Italy and now I'm far away from my country, I would go for option 2. Do you know if it is possible at least to recover my photos? Honestly that's the most important thing for me right now and unfortunately I forgot to enable the backup (my bad!).
We can speak in private if you prefer, send me a message with the details of the person that helped you.
Thanks!

Just to update everyone on the status: my phone is still bricked. I contacted the guy suggested by elpaablo but he just suggests to re-flash my phone while I want to recover my data first. I will leave my phone in the closet for 1/2 weeks and then try again to turn it on because I read on other threads that this worked for other people.
I will update this thread later on. I want to highlight again that I did not do anything weird with my Mi 9 SE: no twrp, no custom rom, no weird flashing, nothing. I just updated successfully my phone to the global stable using the official update menu in the settings.

Use your warranty. Your phone should be replaced. As for your photos, didn't you use some kind of backup, like google photos?
