Did you lose the imei before or after flashing the modem?

i know my real imei. But now imei is null/null after flash a custom rom.. after that i flash modem file. then my imei is 0049....
You lost the real imei after flashing custom rom or modem?
Usually, a custom does not touch the modem or bootloader partitions as it is dangerous, especially the bootloader.

Any solution plss
Usually, flashing the latest stock rom from sammobile.com via Odin would fix the problem.
You could also Google nvwriter to see if you can find a software solution to inject your imei.

I tried many stock roms. and latest rom from Sammobile and nothing changed..
Usually, just flashing a custom rom would not touch the efs folder. After flashing the latest stock rom, does the bootloader match the modem?
Did you google nvwriter?

sorry, what is the nv writer? it is helpfull my exynos s4?
I don't know if it will help you but here is link to it: http://forum.xda-developers.com/showthread.php?t=1804117
I suggest confirming that the bootloader and modem match after flashing a stock rom. If they don't, the rom is not really being flashed.
Thanx for your helping, but i think nv-writer is not helpful for EXYNOS phone.
Then I can only suggest that you try and flash the latest stock ROM again and confirm that the bootloader and modem match. If they do and you still don't have a proper imei, you may have to contact a cell repair shop to see if they can restore the imei and ROM via jtag.

Downgraded from official lollipop to ozcanrom 4.4.2 imei null... flashed your modem then imei is 0049....
i think it is not about modem file. about efs. right?

Yes, it's of course about efs, but i have repaired my imei and baseband null using this mathod.

sw rev check fail device 4 binary 3 on galaxy s6

Hello!! I have one galaxy s6 (sm-g920f) and i try to restore it back to stock but every time i am trying to flash it via odin i am getting this error:sw rev check fail device 4 binary 3.. i have tried with full rom( AP,BL,CP,CSC) with and without pit file and with the rom just with the ap and nothing..i have also tried to flash with kies and smart swich and i am getting the same error... i have done all the wipes from the recovery (twrp) and still nothing.. only if i try to flash a custom rom from twrp will boot...now i am downloading the firmware of my device according to my serial number to flash it.. i also tried the method to flash like if you get sboot.bin error..
Can anyone help me please??:fingers-crossed:
i just flashed it with a full rom but without the bootloader(only ap,csc,modem) and it works!!!
now the problem is that the bootloader is another version from the rom, i cannot see any version of modem, the imei and the product code are blank... i checked them with the phone info app.. now i am downloading the rom with the baseband that shows me the phone info that i have... i also noticed that if i flash a rom which is one file or a rom that is full (bootloader,ap,modem,csc) i am getting error at cm.bin which is on bootloader.. that's why i can install a full rom but without the bootloader file...
Anyone????
i am always getting error at the cm.bin on odin...
i solved my problem by flashing the full stock rom according to the bootloader which was stucked in my phone

HOW DID YOU FLASH IT CAN YOU PLEASE ELABORATE. I have G920P running 6.0.1 and having the same issue while flashing 5.1.1
Cannot downgrade from 6.0.1 to 5.1.1.
SM-G920F, bought with Android 6.0.1. Phone Info says the phone is manufactured in 2016.11.15. Tried flashing same region Android 5.1.1 via Odin and got the "SW REV. CHECK FAIL. DEVICE: 4, BINARY: 3". Managed to reflash 6.0. Is it possible that the newest 6.0.1 (G920FXXS4DPJ2_G920FOXX4DPH1) won't let downgrade?
You can't downgrade the bootloader version. And since the bootloader it's changed at almost every update, you will only be able to install the latest software version for your country.
If all fails, try emergency software recovery from SmartSwitch

Hi you listed a number of files there, where did you get them as they are not available on the search on these forums, I have the same problem and have managed to get this far from The Binary 1 error so making progress, I now just want to flash the lot so could do with some help on where the the files are.
I used the XEF OCT G920FXXS4DPJ2 Modem+Bootloader which i found on here which has given me a working ish Android phone, the touch screen is flipped on a vertical axis so I am looking to put something else over the top of everything to get it working properly again!
Thanks in advance for your help

[Help] S9 plus SM-G965F baseband changed to unknown

Hello There Guys
I rooted my device using TWRP, flashed two different modems in the hopes of getting my Imei ng problem fixed, which it didn't. After that i flashed the factory firmware again using odin and selected the nand erase and repartition options (don't really know why). When booted up after the flash , baseband and IMEI went "unknown". I rooted again and restored my efs file yet the IMEI and baseband are still unknown.
Please help me.
Did i somehow hard brick this phone?

I'm not really familiar with those errors on this device but, maybe try to flash stock modem and bootloader? What is your current software version?
Imei status: NG was problem of patch, you should not have messed with modem instead opened a thread about imei status:ng which i could have fixed it online for you via teamviewer or something. Now as it stands you need to flash latest firmware BL, AP, CP, CSC then PM me.
