I have an S6 Edge G925F phone, witch have Android 5.1.1
In order to update it, I downloaded latest firmware with Android 6.0.1 for my country from samfirmware.com
Used Odin to do the upgrade and everything was fine
After restart, no network only!
My IMEI changed.
What can I do to fix it?
I can't add photos to show you all the details!

flash mm bootloader and modem then reflash the stock firmware. what exactly did you flash?
This is the ROM I'ved flashed with:
https://www.sammobile.com/firmwares/download/106392/G925FXXS4DPJ2_G925FOXX4DPH1_ROM/
After flashing I found that the phone was rooted and tha was the cause of IMEI change.
I can't flash to stock firmware cause I can't downgrade from Android 6 to Android 5.
Tell me what more information do you need in order to find the right fix for my problem?
Thanks a lot!

You can not downgrade. So flash this mm firmware with updated bootloader and modem
I've done flashing that ROM, but the problem is steel there!
I don't know what mm stands for?
Shall I try anything else now?

MM just stands for marshmallow. Have you tried a simple reset network settings?
Go on settings, backup and reset >reset network settings. Then reboot. If not working try change the network to gsm.
Done that, but nothing changed!
Some say that I have to rewrite the RF CAL files, recalibrate the radio part.
Using code *#0011# I get:
IMEI STATUS : NG

Corrupt efs files is what this is. To be honest it's very hard to fix, I'm yet to know anybody to successfully fix it. Not sure what to suggest other than try another stock ROM.
you should have made an efs backup and now you have got yourself in a world of trouble

Guys I need help please!
I was travelling the last 3 months with my S3 and my phone said there was an update and I did it (I was in Indonesia). Coming back to my country (Chile) I had no signal. After reading some forums I think I screwed up. Baseband is XXEMG4. IMEI is the same as appear in the back of my phone (I searched for it dialing *#06#). I don't know what to do to fix it. Sometimes I get signal but when I try to call it says that im not registered in the network. My phone is rooted but before upgrading I didnt backup the EFS. I factory reset it and nothing. Is the anything I can do?
I have signal but can't register to the network! But then the signal is lost and then comes back. Also can't call.
Please help me, I would appreciate a lot!!
Thanks for your time.

you can try to flash with odin , again
for change modem
1- open any firmware with winrar and extract "modem.bin" in your desktop
2- you can flash modem.bin in PHONE with odin
edit- firmware mg4 change efs partition - is not possible flash old modem but only mgX series
only with backup efs folder is possible downgrade

i'm from india and i flashed XXEMG4 the day it was released and after some days i was unable to make calls and was also unable to text people randomly! then i just flashed the indian f/w XXEMG5 and then the problem is no more! flash XXEMG5 via odin and check the result. if you face the problem again, flash the f/w-s that are released after MG4.

You tried flashing back your former firmware ?
You have posted only half the story, what had been done to the phone previously? If your efs was patched, or kernel & modem, to fix botched repairs then you will have to repeat these patches each time you flash a firmware.
No. because I don't backup before flashing ??
Hello,
Tried all ROMS, none is working, below is the detail:
Installed
1 . CRISSCROSS ROM - no audio, while on call in earpiece and loudspeaker
2 . XtreStoLite-ROM-3.3.1-DPDP.zip ROM, Problem - AFter flash Phone model shows G925F AND NO CONNECTION TO NETWORK, EMERGENCY CALLS ALL TIME, TRIED flashing MODEM for g925w8 no LUCK
3. KIngfisher ROM, after flashing Kingfisher ROM, phone is STUCK AT
*KERNEL IS NOT SEANDROID ENFORCING* and phone will not turn ON.
SO , I guess there is NO working CUSTOM ROM fOR G925W8,canada. At the end I flashed stock BOJ7 AND Phone is working perfectly with 5 1 1 G925W8 BOJ7
I'm using the G925W8 on Xtrestolite. You must be missing something. I'm not sure what though

5 Does this rom have spanish langauage? can you check for me?
Thank you

Custom ROMs for that work for W8
I've have confirmation from multiple users that my OZOP Rom is compatible and working flawlessly for the following devices Flat and Edge (rom is Edge based) F/I/T/W8. Could be more this are just the confirmed working devices.
Also OZOP is currently very active with development and actually about to be updated!
What ever Rom you decide is up to you.
Just letting you know there are options available.
Good luck
I believe you need to update your bootloaders using a stock 6.0.1 image or flash them via odin.
Also look in the T mobile section for a custom kernel like stang has a rom showing for. Our devices were basically secondhand tmobile rebranded as W8. Everything is literally the same minus us canadian guys cant use wifi calling.
So in short flash rom, then kernel and let it boot. Once it boots then turn it off and restart into recovery and flash call fix. If you need an updated callfix I can post a link here.
I found if you flash all three before first boot the zip from callfix creates a bootloop. Therefore it tells me the zip needs to be flashed over a built system
Nothing seems to work, No matter what I have No network connection... on any rom..

So the best I've been able to do is get it on a custom rom with no network connection at all. Seems like Im losing the ability to get it working. I tried Wind, telus stock 6.0.1's and i get the SW rev error, I've tried Rogers 5.1.1, and I get the same. Only thing that flashed on my device was "AP_G925W8VLU2AOG2_CL4808800_QB5701859_REV02_user_low_ship.tar" but it didn't boot past Galaxy S6 Edge logo, and recovery wasn't loading to try and factory reset to continue boot. I'm pretty sure this phone is dead.... I mean the custom rom was 6.0.1 with arter kernel, but no service... I'm lost...

Thanks Sir.
Any ideas to my posts above?
guaranteed it's the bootloader and modem.
Once you flash the 6.0.1 ones via ODIN, then both crisscross and xtrolite should work. Crisscross, you will need to flash an independent audio fix which Christ have provided you in the post above.
Xtrolite (which I'm using with Twisted V4 Kernel) has it integrated so you shouldn't have any audio problems. Mind you, if you're still having trouble. Flash back 5.1.1 stock kernel and then let it update officially via samsung kies or OTA. Our phones now have 6.0.1 release so once you do that, you'll automatically have the new 6.0.1 bootloader and modem for our 925w8 phones. Then it'll be simple to flash a custom rom at that point.
Just update stock system to Marshmallow 6.0.1 (or flash stock 6.0.1 via Odin), then flash TWRP, do standard wipe with TWRP (Data, Cache and Dalvik), flash XtreStoLite via TWRP and everything will work
I have canadian S6 Edge and XtreStoLite is working very good

issue is I can't make the 6.0.1 stock files flash, always getting the SW rev error when cm.bin tries to flash, I've tried, Rogers, Wind, Telus stock files, nothing works. On CrissCross right now but not service... I want to get back to stock or at least make the bootloader work.
EDIT: Apparently using the most recent koodo stock, got me back to stock rom and with service! Now to root and do the custom rom properly! Thanks all!

THIS G925W8 is working perfectly in 5 1 1 , I was able to make calls to all networks including GSM and WCDMA, I checked IMEI status with code 197328640 and IMIE status is OK, then after I flashed 6 0 1 and then the IMIE status turns to NOT GOOD and I am unable to make calls and stuck at EMERGENCY CALLS, looks like this PHONE IS JACKED??

Yes before you proceed you will need to install a "custom recovery" (Search about it if you dont know what it is)
Go to recovery like you want to format but instead go to "Backup & Restore" and select backup and then select "efs" which is IMEI.
After flashing a custom rom and after the first boot you will notice that there is no signal, so go to recovery and select to restore efs.
I recommend you to backup efs to ext sd card.
This will void your warranty, even downgrading it self will void it.
Goodluck!

Any firmware 4DPG1 or above can not be downgraded. Im guessing before you was on U3DPAD or lower which can be downgraded. The first MM builds could be downgraded. But any 4xxxx can not
ah ok....
then i downgraded fast enough
my main reason of downgrade:
in MM it is not possible to change the font with HiFont App....!!!
i see other people saying that it's possible.
but i have one of the latest builds so, in your opinion , it is impossible for me to downgrade.
but are you sure? i can't believe that, i want absolutely a solution, i am searching it from so many time, please help

What build number are you in? It is impossible to downgrade from a late build 4xxxx. I have tried absolutely everything. The only way is to flash a nandroid backup but even then you will lose imei. You can always back up efs and restore but its not always as straight forward to restore it. You would also need to flash a new bootloader and modem.
Did you make a nandroid backup of your previous firmware? If not then you cant try that.
The only other way you can try is to flash a 5.1.1 custom rom. Again you will lose imei. So efs backup is important. You would also need to flash BL and modem again.
There are roms based on lollipop which is a much safer way to revert back, try one of them.
Overall i wouldnt try it bit its up to you. If you do and you find a way to do it let me know.

You cant downgrade after 4xxxx firmware mate. After updated bootloader your stuck on mm.
There are ROMs based on 5.1.1. But because you flashed 4xxxx firmware you cant downgrade. All lollipop firmwares are 3xxxx

I got a customer who wants to downgrade from Android 10 to 8. I know Samsung has anti-downgrade protection and you can't flash older firmware using Odin.
What about rooting the phone first though and flashing the Android 8 firmware using TWRP? Wouldn't that work?

My phone is already rooted and do you have any guide how can I flash complete firmware through twrp with bootloader. Actual problem is bootloader which can't initialize previous version of modem. I have downgraded modem but it does not pick IMEI.

You'd have to flash system, vendor and a kernel that can run Android 8. Just flashing the firmware straight up won't work

I mean, I've done it on other Samsung phones, yes. Updated officially to Pie and then flashed an Oreo ROM that includes system, vendor and kernel images and it runs fine.

How you have done it? Samsung boot loader won't allow you to downgrade !

I don't need to downgrade bootloader, just need to flash the ROM which includes system, vendor and a working kernel.
I'm speaking strictly about running Android 8, not downgrading. So this method of downgrading to Oreo probably won't help you on your problem
Can we do it with firmware combination file or eng modem?

I guess we both having same issue. I upgraded to UAETG3 and the mobile signals were gone. IMEI status is 'NG' and it says emergency calls only. The binary of aforesaid update is higher and it won't let me downgrade. Have you found a solution?

Try to flash complete firmware from odin and if not then your efs is corrupted !
I think combination file might downgrade with re partition
Any information how to downgrade modem and bootloader?
