have you updated the baseband?

maybe need to flash NON-HLOS (Wifi Fix). This is the LTE modem and should match the installed baseband otherwise wifi and sound problems may occur.

you mean reflash the new ROM again, or same old ROM? I don't want to go back to my old stock ROM due no kitkat update for it..

I just had the same problem as you. After a lot of reading, this is how I solved it:
1) Wipe data/cache and re-flash the original stock rom (everything back to day 1 from new)
2) Donwload and flash the modem for the new ROM you want in the phone slot
3) Flash the same new modem again, but uncheck "auto reboot". Once done, manually turn off the phone
4) Flash the new modem a 3rd time with "auto reboot" checked again. In settings > about device, the boot loader should now be updated.
5) Flash the CWD recovery (or custom recovery of choice)
6) Flash the new ROM
DONE

I have flashed the modem successfully, now the baseband has been updated. Then I reflashed the new ROM using ODIN. But still the wifi doesn't work.

Update Baseband from MK6 to NE1 ?

Okay....Feedback appreciated : I was on a 4.3 ROM running basebandI i337MVLUEMK6. I then installed both Hyperdrive and
GoldenEye. Little did i know, I was on GSM NOT LTE. So.....I believe this is my issue.
The newer 4.4.2 factory firmware is NE1. So what do I do to get on LTE Rogers? How can I update to the latest
baseband without locking myslef out of Root access and custom roms?
Thanks

Anyone.?

Look for and download the file ending in .tar for Rogers or any canadian S4. They all use the same radio.
Use ODIN to install in Download Mode (Power button + volume down)
Use the PHONE option for radio on ODIN.
Check your “Baseband version” under About->Settings, after installation
If your radio version hasn’t changed, try re-flashing with ODIN but with “Auto Reboot” unchecked.

Thank you for the reply. Baseband is currently i337MVLUMK6. What SHOULD it be? I am connected now on
4G service.......

The current baseband for Canadian phones is NE1. You will have to download the latest firmware file for NE1. (I337MVLUFNE1)
Extract (unzip) the firmware file
Download Odin v3.09
Extract Odin zip-file
Open Odin v3.09
Reboot phone in Download Mode (press and hold Home + Power + Volume Down buttons)
Connect phone and wait until you get a blue sign in Odin
Add the firmware file to AP / PDA
Make sure re-partition is NOT ticked
Click the start button, sit back and wait a few minutes

Great. Thank you!
Once complete, will this lock the phone from being rooted or will it KEEP ROOT?
Thanks

You will have to re-root. You can use towelroot to ROOT the phone. Very easy and convenient.

Thank you. Much appreciated. I'll let you know how it goes.

Firmware - HOME_CSC - Odin 3.10.7

How to flash the firmware (5 files in archive) to your s7edge?
AP, CP & BL I understand, but the 2 CSC-files...?
CSC -> there's a PIT inside and will wipe your device
HOME_CSC -> the data should stay on your device
Today I tried to update with HOME_CSC, everything was OK, but at the end Odin 3.10.7 FROZE at "meta-data" (this folder is in the HOME_CSC file): nothing happened anymore and I had to pull the cable
Smart Switch didn't recognize my S7edge anymore for the "Emergency Firmware Repair"!
Luckely, Odin did recognize my device and could install the firmware with the "normal" CSC-file and afterwards my device was reset...
I hope someone has a solution on this, because I don't want to install everytime again and again...

same happened to me. I have the same question...

How did you get your device working again?

Well, the flash went just fine. No problems except the device reset at factory settings. As brand new one....
But of course I would like to know how to flash without resetting the device.

I had the same problem yesterday when used Home_CSC... flashed again with normal CSC and went back to normal with a formated user data
We really need a solution to that... What would happen if we skipped the CSC file when flashing thru ODIN?

Flashing with CSC and not home_CSC will also reset your CSC.
Eg: I was on VODAFONE Romania and flashed stock unbranded using CSC. The result was I lost my ROM (from Romania) CSC, and defaulted to XEO from the multi CSC.
In this situation you cannot go back to your original CSC even after flashing using Smart Switch.
Rooting is the only option then and that will trip Knox.

anybody figured this out?

Just had the same problem flashing with HOME_CSC it got stuck in ODIN and had to pull the cable.
Had to turn off phone and boot again in download mode to flash again with a straight CSC.

CSC contains an instruction that allow Odin to wipe the DATA
Code:
--update_package=CACHE:recovery/sec_csc.zip
--carry_out=csc_factory
--wipe_data
HOME_CSC contains instruction only to allow wipe of cache BUT the original HOME_CSC can cause Odin to freeze at the end of the flashing process.
Code:
--update_package=CACHE:recovery/sec_csc.zip
--carry_out=csc_home
--wipe_cache
That's why you need to modify the HOME_CSC using the CYGWIN tool.

Just dont flash the home csc. I never did it. Everything work greats.

HOME_CSC is supported on Odin version 3.11 or later. It's okay to flash it now.

Sorry to revive this thread but when a downgrade is done from Nougat back to Marshmallow a factory reset via recovery must be required if flashing HOME_CSC. Otherwise just use normal CSC on downgrade.

thank you

How to reinstall firmware on S7 edge?

Hi everyone. I am having battery drain issues after i installed the September security update. I want to reinstall the firmware on smart switch by connecting to PC.
The last time i tried it through emergency software recovery in fownload mode, I almost bricked my phone. Can i reinstall using device initialization option? Which one would be better?
Thanks in advance.

When you brick your device it has nothing to do with Odin (use the latest version)
Make sure you install the right firmware for your device
Import the appropriate files to Odin exactly where they supposed to be
You'll have five files when unpacked downloaded package
Installing CSC will wipe your device, to avoid that you have to install HOME_CSC instead
You may also need to set a password for a secure startup as it may ask

Hey again, @Geoz
I have two questions:
1. I can't get FOTA on my S7E, I think because the CSC file. Can I really flash the "HOME" one and not wipe data?
2. If I want to flash another Stock ROM, I must set secure startup? And if I forget, there is any solution?

If you want to flash different stock firmware other than your region, flash the three (BL, AP, CP ) and use your original HOME_CSC (you are aware that you have to start all over), installing your region stock firmware with HOME_CSC will not wipe your device.
If you forget password use (default_password) without the brackets but it's important to set it before and use it only if you forget

But if I will flash other region FW and my own country CSC, I won't be able to get FOTA. As far as I know, The FW and the CSC has to match to get updates.
About password for secure startup, I mean, is it really necessary to set it before flashing new ROM? I must set it up?

Wifi, bluetooth and Mobile data not working N9005 LTE model

Hi,
Installed a Custom Rom Cm14.1 in my N9005 LTE version. After Some time i prefer restoring it to stock firmware. So I thought of restoring the TWRP backup file. Unfortunately, while restoring TWRP showed some error. Modem file not present ( not the exact error words).
Because of the error in performing a restore. I installed LineageOS. But the wifi, bluetooth and Mobile data is not working. Then I tried installing many stock firmwares of different countries downloaded from Sammobile, updato, etc but no use.
I tried downgrading my phone to Kitkat 4.4.2 and then upgrading it to Lollipop via Kies. But still wifi bluetooth and Mobile data is not working.
Please help me. Wifi and bluetooth is greyed out.
I also installed the "wifi and bluetooth fix v2.55 s5.zip" but no use.
Is there any other way. Please help.

First check your IMEI is correct .

Yes. IMEI number is correct.

Anybody to solve N9005 wifi bluetooth problem? Waiting for expert's advice. Please help.

Will restore TWRP file of stock Rom help in getting the WIFI bluetooth and Mobile data working?
If yes, can somebody upload the RESTORATION TWRP FILE (backup file) of N9005 LTE version.
Thanks in advance.

Depends upon what problem is but yes worth flashing stock rom via Odin .

Was Odin successful in flashing a stock ROM? If not, post the Odin log errors.

Thanks for the reply. ODIN stock Rom flash was successful. No problem in Odin flashing. I tried different country stockroms, No problem in Odin flashing. But the problem persists.

What is your CSC ?

DXUGBOK3

Any help?

You need a service repair .

You flashed the latest stock ROM in Odin? Tried flashing with a pit file?

Yes flashed the latest stock ROM with ODIN. But England STOCK ROM. Pit file too.
