Beckup necessarily need? necesarily to restore IMEI and signal or Something Like That?
Sorry for my bad english.

Hi,
Are you saying you have a backup or need a backup? Also what type of S3 do you have - what is the model #? As that determines what ROM you then load.

[Q] Galaxy A5 LDU

I have a galaxy a5,it is a live demo unit SM-A500xz.
I have flashed the official SM-A500F firmware with Odin and it was successful.
Now the phone shows SM-A500F in bootloader and software,when booting it doesen´t say live demo unit.
I have insert a sim card and the icon with no sim card disappeared but no network.
I have another A5 with a dead pcb,if i write the imei from the dead pcb will it work ?

I have an XZ unit, yesterday i've tried to flash the XU (ITV) Firmware, but didn't start...
I will also try with the F version and see...

Any body ?

Sadly i don't have anymore the A5 to test, i was stucked at almost your same point.
I checked the efs, there isn't the nv_data.bin file...
But you can try to set a new IMEI with EFS_Professional.
I had this idea only yesterday, but i just was without the phone to test...
Let me know if it work or not
PS: Sorry for my bad english!

Hi, I have exactly the same pattern .. can you help me with the IMEI? . the next steps? ... thanks

Samsung Galaxy S7 SM-G930F - No Network (SIM - CARD)

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

Hey, flashing a Stock Rom with Odin + Root works for me with no problem, how can I flash my EFS? I do know my S/N and IMEI number..

Do you have an EFS backup? If yes, this may help: https://forum.xda-developers.com/showpost.php?p=72355071&postcount=3

I don't have an EFS backup. Any chance without a backup? I do know my S/N and IMEI...

You would need a way to recreate the contents of the folder. Unfortunately, I'm not sure how to create the contents.
Maybe this will help: https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-fix-check-drk-imei-issues-t3379516

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

S7 g930f help neeeded cant detect sim card after flashing custom rom

hi, i got problem...i had stock oreo oficiall without any mods and i decied to flash some custom rom like s9 port teamexyking, now i cant detect any sim card on any custom rom....some help??? i flashed modem and bl and still nothing... looking for solutions, mb some1 can help..ty

I had the same issue and I think it was the same ROM, but it only happened after a day.
Re-flashing the ROM via a dirty flash didn't make a difference.
In the end I just changed ROM because I didn't want to spend too much time on it which worked, so it hasn't done any permanent damage.

Have u checked your imei number or baseband version ???
If baseband version is unknown or imei is null so u can't get netwrok
Or u have damaged your efc partition???
If u have none of this above problem
Than u should check your sim tray or go back to official stock firmware because I'm also on tha same rom by teamexykings and it's working superb

@up indeed my friend, i flashed official latest oreo xeo and its works... Ty for ur help guys
