Soft brick with no efs

Hi
Unfortunately I haven't done backup before I bricked my phone. I've tried Odin to upload new roms, and Bootloaders, but nothing help at all. The phone stuck on logo.
I don't have efs, but I have access to recovery and to download mode. What shuld I do to recover my phone? Is any method to manualy put my IMEI by Odin or recovery?
In recovery <3e> I have E:failed to mount /efs (Invalid argument)

download the rom from here
download odin to pc and follow instructions to get back to stock http://www.youtube.com/watch?v=_8Tga_yKywc (skip till minute 9:00)
cheers and good luck

thats always scary

Thanks for reply
I also flashed rom from sammobile by Odin, and still stuck on logo. I m afraid only service can help me.
Thanks anyway

go to recovery and do a wipe data/factory reset & wipe cache and reboot..

I did wipe, factory reset and still stuck on logo. On recovery I have still on red E:failed to mount /efs (Invalid argument)

Anyone know maybe it is possibly to create efs folder with my IMEI from phone(under battery) and implement it by e.g. Samsung GS3 Int ToolKit???

Try flashing right modem through recovery, or use Odin to flash stock rom or you can try kies to recover it.

Thanks for your reply.
Currently got stock rom on phone but it won't boot, it's stuck at Samsung logo.
Device is rooted and got twrp.
Kies is stuck trying to figure out the device that is connected. And when i try recovery of firmware or something of the like(Kies is installed in french) says this model cannot be reinitialized.
Also like i said i have no backup, so no recovery key for kies either.
But the internal sdcard is recognized by Windows.
Don't know what else to do. I had no problem flashing modem.img flashed OK and such.
Is it normal when in recovery mode when i run a graphics test it says error?
Is it just a bug from the recovery mode?

Hoorray! Found Something that worked for me i'd like to share with you. Thanks to this post : https://forum.xda-developers.com/s6-edge-plus/development/updating-t3210266
Many thanks!!

HELP! Failed to Mount '/firmware' (invalid argument)

Well I screwed up somewhere. I tried updating my modem and then it got stuck bootloop and now i keep getting that error in twrp no matter what I do I tried to return to stock but twrp can not find the restore as in this guide https://forum.xda-developers.com/le-pro3/how-to/guide-return-to-stock-lock-bootloader-t3539513. I tried flashing everything Manually except system.img as in this guide. https://forum.xda-developers.com/le-pro3/how-to/guide-how-to-manually-upgrade-firmware-t3609786. Still no dice. I'm unfortunately stuck and can't figure out how to fix this. All i have acess to is TWRP which always gives me that error Failed to Mount '/firmware' (invalid argument) and Fastboot. I'm sorry if this isn't posted right. I tend to not post very often. Thank you in advance My device is X727

My Axon 7 dosn't want boot system.

My phone dosn't boot system. It happened automatically yesterday. I can boot into TWRP 3.2.3-0. There is info about Failed to mount '/data' (Invalid argument). Is there any solution to recover data? I don't want to lose pictures.

One possible way to recover your data is TWRP 3.2.1-8 by NFound, get it from his androidfilehost page or maybe somewhere in this forum (roms, kernels, development probably)
