Hi, I flashed xtrestolite on my phone and after booting up both my imei and baseband numbers became unknown; I now can't connect to my mobile network as my phone doesn't detect my sim.
I've tried to fix this issue by flashing other roms as well as flashing various official firmwares downloaded from sammobile to no avail.
I remember having the same issue with my gs3 and fixed it by flashing cyanogenmod. I tried this as well but the phone wouldn't boot up after flashing the unofficial version.
Could someone please help me with fixing this as I've been trying to for 3 weeks now.

The phone originally for vodafone uk and you flashed the latest firmware on it?. I think nothing can be done except restoring the imei from backup manually.

The phone was on version 6.0.1 and I flashed the same firmware versions. I deleted the backup of the original firmware unfortunately. So does this mean that nothing can be done to fix the phone?

Try reinitialize the phone using smart switch. Hopefully it could fix the broken imei. Flashing the correct firmware(odin/smart switch) sometimes helps to restore imei.

Hello,
For some days I had a thread where my audio suddenly cut off or some weird noises appeared.
https://youtu.be/a1TaBH11bTI
What I´ve seen the problem is not uncommon and it is software related. So I wanted to ask you about your experience, could you fix the problem by flashing a custom Rom?

It is different because I think it software related and I want to know if it is possible to fix it throught different Roms.
My prior thread was different I didn´t know why it happend.

Happens to me whenever my phones swaps from WiFi to LTE or vice versa. Otherwise if it is a software issue it's most likely a bootloader/modem mismatch. Have you been jumping between 6.x and 7.x Android? Because if you use a 6.x bootloader/modem with a 7.x android or the other way around, it will break vibration and other aspects of the software.

No, I stayed on android 6 never updated or downgraded but what do you mean with modem? or bootloader/modem. Maybe I should add that I rooted the phone to gain twrp and root. And vibration and other stuff works well besides this sound problem
There are 4 firmware components, the OS/ROM, the bootloader, the modem, and the carrier config. When you change the OS/ROM, you should be changing the rest to match.
If you've stayed on android 6 you should be okay, however it's not a bad idea to go to updato.com, download the most recent 6.0.1 stock firmware for your country/carrier and flash the bootloader (BL) and modem (CP) files. There's a guide on updato.com showing the step by step process, just make sure you don't do a full flash. Only the bootloader and modem.
Since the bootloader is essentially the backbone of your phone, it's always beneficial to have it up to date with your version of android (Don't use a 7.x bootloader on 6.x). Modem updates also help with your phones signal and data performance.
You should find most ROM guides say always update the bootloader and modem before installing the ROM.

And that is how you fix your problem? Update the bootloader and modem? But after the flash I can still keep twrp or do I need to do the process anew?

So thats the version with the correct AP, CP and CSC when I flash the modem and bootloader everything should be fine I hope.
Yea my problems were fixed doing this, and if you only flash BL and CP you won't lose any data or TWRP.
I can't guarantee it will fix it, but it's a good start.

Hello Guys, this forum is my last hope. I have a problem with my S7 (DBT Germany), I think after flashing an older stock rom and going back to newest, something happened that my phone doesn't detect any sim cards anymore. If I type *#06# , it only shows the SN Number, no IMEI. WIFI still works without problem, but I can not use my sim card anymore, so it's pretty useless now :crying:
The sim card works on another devices, so it's for sure a problem with my s7, I might have messed up something. What do you think is here the problem and how can I solve it? Any help is much appreciated, I really hope to fix this because my phone is only 2 weeks old.
I currently have the latest Firmware for DBT from updato, (December 14, 2017 for Android 7.0)
IMEI = unknown
SIM Card status: Not avaliable
Have you tried a stock ROM from sammobile.com? Updato and sammobile.com should have the same ROM but maybe there is a difference between the 2?
Did you confirm that the phone is running the latest modem?

I did not try sammobile because updato and sammobile were the same firmware. Sammobile does have a newer firmware from 28/01 but it says I need to join in order to download.
Is there a way I can fix a damaged/corrupted EFS ? My phone is pretty useless now without sim card detection
Sorry, I know of no way to fix imei issue if a combination of Odin and a stock ROM does not work. You may have to take it to a cell repair shop that can force flash the ROM and EFS using hardware like an octopus box: https://octopusbox.com/eng/features/models

You would need a way to recreate the contents of the folder. Unfortunately, I'm not sure how to create the contents.

Hey, I have finally found the solution and my sim card is working again :victory:
It really was just that the firmware was 1 version older.. I downloaded the latest DBT Firmware from samsung-updates (Build Date: 15/01/2018)
Put Bootloader to BL , AP to AP , CP to CP , CSC (not Home_CSC!) to CSC , flashed it and finally my IMEI etc. is back.
Thank you for taking your time trying to help me
Congratulations on your success
EDIT:
I was able to fix it! I had to install a custom ROM to obtain root and delete my EFS partition.
So, here is a bit of a story I will try to keep short.
I went to Vietnam and bought a S8+ from there.
It was a US S8+ from Sprint.
I used it fine there but when I came back to states I tried to put my Verizon sim in and it doesn't work.
I don't get any signal. But I am able to see Baseband and IMEI.
So, I tried to use Odin and flash one of the SM-G955U1 Firmware.
Now, my phone is weird and out with no Baseband or IMEI.
So I try to flash back to firmware it was on.
Same thing.
Any ideas why my S8+ is like this?

What happens if you restore from the OEM function?
Try downloading custom recovery and flashing a custom rom. You will lose samsung pay but you might have a working phone it's a chance I would take if it was me. Your baseband is messed up try just flashing your carrier baseband . These are just ideas good luck
Sent from my [device_name] using XDA-Developers Legacy app
If flashing a custom ROM will fix your phone then so will downloading latest official Samsung ROM and flashing via latest Odin .
The second option above would be the best to try unless you're happy to have a custom rom and lose Samsung pay and anything that relies on Knox being functional

Update on the post, I sent it into Samsung. I should hear word soon if they can fix it and how much if anything.
Jtag dead phone to life and rewrite IMEI
First of all my phone is the s8+ G955fd, but I am sure that the people that helped me can help most Samsung owners with bricked phones.
My phone ended up being stuck on the first boot screen, I couldn't get into recovery or download mode. I installed TWRP and after that I lost my IMEI numbers( dual sim), so I tried to reflash stock and thats when i became bricked. I searched someone to help and found reference to the Fonefunshop in England. I sent it there and they said that the eMMC chip was bad. I searched for someone who could write to it or put a new one on the motherboard . I found A2Z cellular in Ottawa Canada. They used jtag to restore it to stock and they told me that the Fonefunshop had not opened the phone which is necessary to use jtag as they claimed, so avoid them.
The phone was now back doing everything it should except the IMEI's were null like before. I gave them the original IMEI's and the phone is working like new.
If your Samsung is bricked these guys can probably fix it and it won't cost much to find out.
the SM-G955U has a locked bootloader, so people should not be telling you to flash a custom recovery or custom ROMs. there is only one way to get root on this phone, through the samfail exploit, and safestrap is the only working recovery. I don't believe it supports CDMA networks but I'm not 100% sure on that. I have this device and I'm only aware of GSM carriers using it.
Just an update on this issue. I still don't have a working Baseband or IMEI. Any clues?
I was able to fix it! I had to install a custom ROM to obtain root and delete my EFS partition via ADB.

Be very careful with doing that. It can cause the EFS (the partition that controls IMEI, Mac and a few other things) to be completely corrupted. Which will cause the device to be useless without fixing it.
Now a little heads up. As messing with the IMEI is illegal in many countries (the US being one of them) There are only 2 ways to fix an IMEI issue allowed on XDA.
1. Restore the backed up EFS partition
2. Return it to the OEM to be repaired.
What did you do after you deleted EFS? I can delete in Combination but I dont get the IMEI number back.
Please I need all XDA members assist ,because of I mistake delete EFS with combination file on my G955U VZW , I have null imei number, then I repair it by flash qcn with z3x Samsung tool , but still I have IMEI number but emergency call only is still display without service ,
Well, I have a device called "Tectoy ON 5029Y", the same as "Alcatel 3L 2020" (White Label), I'm trying to install a GSI on it, but I lose the IMEI and Baseband every time I unlock the bootloader, but if I block they come back, what am i doing wrong? I've done a lot of research on this device and there is little useful information.
I've already started GSI's, but they also have the same problem.

It will restore your IMEI, if it relocks your bootloader, you can unlock it again. Even flashing the newest version of your firmware should restore your IMEI and probably won't lock the bootloader in the process.

I've done this procedure before, about 4 times, the baseband and IMEI are never restored, only when I lock the bootloader. Also, until today I didn't have the stock of this smartphone, I used the Alcatel MU to restore it.
edit:
before I had restored after having installed the GSI, the bootloader did not come back locked, this time it came back! Then I unlocked it again and the IMEI disappeared again.

If you don't have EFS backup the only thing I know you can do is flashing stock ROM. That is what has been sorting it out for me. I think I've managed doing it once with ROM which was based on stock but I think that is very hard to happen in practice.

AFAIK on MTK devices an EFS partition / directory doesn't exist, but an NV ( NVRAM ) partition / directory.
BTW: A Stock ROM - the ROM compiled by OEM especially for each of its device models - never includes a device's IMEI. If it would be so then all phones of such a device series would have the same IMEI - which would be a complete nonsense.

Try to factory reset! When i lost IMEI on ZTE blade X3 its too helpful than i reset when this situation happen. and try to lock BootLoader again. and try to back to original ROM. +Turn off cell network and eject SIM card again and Turn on cell network after than you put SIM card again

I've already done that, the baseband and imei always disappear, when I lock the bootloader they come back. I don't know if this has to do with "Security boot MTK" or "AVB 2.0", I rooted and installed vbmeta, still the same problem remains.
@MrJosh18 Its maybe SIM problem.
Or ROM problem totally. MTK processors too vurneable to any BootLoader actions. Its maybe problems of Android telephony System apps.

Use this CLI tool to back up (Read option) your NVRAM, NVdata and NVCFG prior to unlock it (you can back up any existent partition you want), after that you can use this tool even to unlock it and either, for sake of curiosity or for future reference, see if it produces a different result (i.e. not erasing IMEI). https://github.com/bkerler/mtkclient
Also, you're right, you need to firstly fix the baseband null issue to can fix IMEI. What Droidriven suggested was flashing your stock ROM after to unlock bootloader, a ROM from other device even if it is from a similar or from a rebranded device won't work/make the same that the firmware for your exact model, I know, probably is not available anywhere, but this is a fact.
