Baseband and IMEI info of J7 2016 (SM-J710FN) accidentally wiped - Samsung Galaxy J7 Questions & Answers

Hi guys,
I happened to accidentally wipe the system partition on my J7 2016 (SM-J710FN) through TWRP during a botched rooting attempt. After noticing that the phone didn't boot up subsequently, I managed to flash a stock ROM via ODIN as given in the below thread.
https://forum.xda-developers.com/ga...7-2016-stock-rom-build-date-7th-t3515491/amp/
Now the phone boots up fine, but does not connect to any cellular network as the Baseband and IMEI information shows up as 'Null' in the 'About Device'. And I did not have a backup of the 'efs' folder too.
I took the phone to a Samsung Service center, but the service guy said that since the Baseband information is lost there is no other option other than replacing the motherboard. It kind of sounded lame as this is evidently just a software issue, and the device works perfectly in every other way.
I attempted the 'Emergency firmware install' option via Smart Switch, but the tool does not recognize my device even after the manual entry of Model Name and Serial Number.
Is there some other way I could try to get this issue fixed? Any help or suggestion would be much appreciated. Thanks!

Could try faking the IMEI number through some apps, if you still have the box. Otherwise I think it's a lost cause since IMEI number is the device "identity Card number/SSN" as to so to speak.

Thanks. I still 'know' the IMEI numbers of the device (there are two, being a dual SIM phone) as it is there in the box and under the back cover. Do you mean to say there is no way to flash that info back to the device? Maybe something like a template EFS file to which the info can be added through some tool? Just wondering..

The hard part is to find another working efs for this phone which I could possibly use as template for other tools that can alter the IMEI.. I did a bit of googling, but it didn't throw up results other than some password protected zips.
Will do a bit of hunting. Thanks..

sir ,plz help , nast night i have installed custom rom "port Note 7 " on my galaxy j7 2016 SM-J710fn , and now its not recognizing SIM Card and Baseband number and IEMI number are also null , Plzzz help as soon as posiible

I Have Same Problem. But After Flashing 4 File Firmware By Sidrose01 For J710FN With Odin. Thats problem Solved. I Use Odin Because Smart Switch Doesnt Work. Sorry for my bad English. But your CSC will be Changed.

If ALL you have done is wipe the SYSTEM partition I don't see how the EFS could be lost/corrupted.
My advice would be to first attempt downgrading the current firmware version( IE Android 7 to 6) via ODIN, this in its self can fix many erroneous issues.
Then, Irrespective of whether the device boots or not afterwards, update to the latest firmware. The essential part is that the device auto boots to recovery after flashing with Odin and completes the update.
Or as posted above find the factory 4 file firmware and flash that. Be aware this will likely wipe your device.

i don't get any mobile connection

Hi guys,
my old N5 felt on the ground and breaked.
So i did a backup using TWRP and restored it to my new Nexus.
Unfortunately my new one can't get any mobile connection.
The IMEI seems to be missing :crying: (see screenshots)
Please advice.
Thanks in advance!!!
Looks like you restored a backup that included efs. EFS is unique to every handset and cannot be recovered without a backup. In short, you just ruined your phone

i know that there is a workaround for this issue for samsung phones when no efs-backup is availabel.
does anything like that exist for the nexus 5?

so it's the same for nexus and samsung?
- flash stock
- wipe data/factory reset
- wipe cache
- reboot
- delete efs folder
- flash stock rom
There isn't an "efs folders" and you shouldn't delete anything. Just flash stock

Actually that workaround depends on what actually happened to efs in the first place. It does not fix all efs issue, believe me

If all else fails, looks like you MAY get lucky if you Fastboot flash each image in a ROM zip manually.

flashing each image in fastboot didn't work
isn't there a way to restore the IMEI manually?
i guess it has to be stored somewhere on the device and i've it on the sticker.

As it's illegal in many countries to tamper with the imei, it cannot be discussed here. Send it to an lg service centre for repair

SM-G550T BRICKED - STUCK ON SPLASH "Custom binary blocked by FRP lock"

My rooted Samsung Galaxy On5 (sm-g550t) is stuck on the black and white SAMSUNG logo boot screen, up at the top left in red is the message : "Custom binary blocked by FRP lock".
I cannot boot into recovery at all, but I CAN boot into download mode, and when connect it to a PC where Odin can "see" it. So that's good I guess.
Things I have tried so far:
1. Reflashing TWRP - FAIL IN ODIN (it worked before!)
2. Downloading new recovery from here and flashing in ODIN. FAIL IN ODIN (https://idlekernel.com/flash-tools/firmware/on5ltetmo_SM-G550T/G550TUVU1APF1/)
3. Recovery in KIES (does not accept my s/n and model combo)
This happened after I tried to partition the drive for use with the Marshmallow "adoptable storage" using directions from this web page.
http://www.modaco.com/news/android/...e-adoptable-storage-on-your-s7-s7-edge-r1632/
I DID do an nandroid backup before all of this happened, but without recovery mode it won't do me much good.
1. Any suggestions. 2. does anyone have the stock firmware tar that I can flash in odin to see if it works? Sammobile does not have firmware for the SM-G550t, sadly.
I really need your help. I can't find anything anywhere that has worked.
I figured it out. Thanks for the offer. I'll posting to the solution.

Yo, I got you. Watch my youtube tutorial on how to fix this:

Go to Sammobile .com or samsung-updates. com and use your model number to find your stock firmware, download the one for your region/carrier and flash it using Odin on PC.

2 questions:
i read that Odin requires .md5 or .tar - are these roms which are found within the zip files .md5 or .tar?
i only see Stock ROMS from Thailand or China - does this matter?

Usually the stock .tar firmwares are uploaded as a .zip to make the file smaller, extract it and you should have a .tar.md5 or a .tar, if it's .tar then you may have to extract that also to get to the .tar.md5.
Yes, typically the region matters due to differences in networks in each region.

What issues are related with kernal?
And is that posible that i extract system.img from the rom and change the kernel file ?

My phone can't connect to any wifi network.

It just says "connecting" then nothing.
I already tried the following:
booting to safe mode
performing a factory reset
reflashing the stock rom
flashing a custom rom (I don't even know how would that help, lol)
resetting the router
Could this be a hardware problem? It can still see wifi networks, though, so I guess it's not? Please help.

If you're right and the efs is indeed broken then restoring wouldn't work because I did the backup after the problem happened so what was included in the backup was the supposedly broken efs.

[EFS corruptes] S8+ G955F

Hello dear users,
I`m facing a very big problem with my g955f. For a while i had 7.0 on my device but yesterday i decided i should update to 8.0. I flashed the latest 8.0 stock (BL, AP, CP, CSC) from sammobile and everything worked great. Problem appeared when i tried to install supersu and it got into a bootloop. I flashed again 8.0, this time without BL because i've got the error "SW REV. CHECK FAIN(BOOTLOADER) DEVICE: 2, BINARY: 1". After device booted up there was NO IMEI...s'o i think something happened with efs partition. Then i tried a fix from another thread and now i get "efs mount failed (invalid argument) after i flash a rom and the phone restarts".
I know i know, i should have made a backup...
The question is, does anybody know how to solve this problem ? Maybe from where to get an efs dump (even with IMEI 000....)
sorry, my english may not be so good
Thank you !
there is only way to get imei back is Z3X box if someone on mobile shop have it otherwise you need to send it to service centre with your recipe & mobile box.

i finally found a combination file for U2 bootloader version but no success. Someone more skilled than me told me that efs partition seems to be effectively deleted. I'll take the phone to a service today and hope this will be solved. Thank you
LE: can you explain what this pit file is for ? i don`t want to brick the phone more than it already is

maybe you`re luckier than me and your efs partition is just corrupted not deleted and combination file will fix it
How can i check that? Do you fix your problem?

No.... still not fixed because efs partition is deleted. What is your phone actual problem ?null imei or it doesn't even boot up ?
I have this stock S8+ Official Oreo CRAP Firmware 14.02.2018, but i can´t find the combination files for it.
It does boot up, but it doesn´t give signal and when i look up in settings for the imei it says unkwon. How can i be shure that the efs partition is deleted?

Oreo comes with U2 version of bootloader. This means you can`t use combination files that have been made for 7.0 bootloader (U1). Yesterday i found a combination file for U2 version. I'll share the link with you but right now i'm at work and i don`t find that link. When i'll be at home(8hours) i'll post the link here(i saved it in bookmarks). Chances for recovering your imei are very high i think. Until then please don't make something stupid with your phone like i did....
LE: if the phone is booting up then i think your efs is just corrupted

Yeah....i`m desperate too....i messed up an expensive and a high end phone.....but that's it....we're learning from our own mistakes ). I think that is the file i'm saying (check if it has "U2" in its name). Download it, flash it with odin (put the file in AP), wait until the flashing process is done and that "gears screen" is on, and wait. After that flash the stock 8.0 oreo and the imei should be back. Hope this helps you. I can't give you an exact method to see if efs is corrupted or deleted.....like you i'm a newbie with all this architecture of android...

I used the combination file and show me the imei so i think it was just corrupted. But when i try to flash stock in odyn https://forum.xda-developers.com/galaxy-s8+/development/rom-galaxy-s8-t3749444 this version, it says device 2 binarie 1 error. So flash without check BL. But then the device doesnt boot and gets stuck in first screen. What can i do?

There`s nothing you can do. Your only option is to stay with 8.0. You can't downgrade the bootloader from U2 or U1 because U2 security policies seems to not be ok with this ). I left my device at a service twenty minutes ago to reflash an efs dump from another 955f....hope they will make it.... anyway, congrats for reviving your device

This message means that your actual bootloader version is newer than the one you want to flash and because security policies you can`t flash an older version. You'll have to flash latest stock 8.0 (bl,ap,cp,csc).
