Update about S9 and Note 9.

Most recent XAA firmware gets Volte activated on Jio automatically. No need to mod anything.
Can someone test their S8 and note 8 with latest security patch firmware and report?

Didn’t work on my S8+.

You cannot downgrade the bootloader version (check if both files have same version or not)

S8+ on BL6

I'm not able to flash the sec_omc.zip during the final step this time around.

All the files including the one I extracted sec_omc_1.zip failed to flash.

Any links to the latest firmware...Or can you tell the version code

I can't get this working for the U series, it keeps saying me it's not signed nor finishes installation (in both sd and adb cases), even if I extracted a newer csc.zip

I followed the steps posted by OP and used this CSC on SM-G950U1 running S6DSI1 using BL6 combination file

I am unable to change the code XAA in factory mode, after flashing with original firmware it came as DBT/DBT/XAA,

Please help to have it changed to INS/INS/XAA to support Jio VoLTE

Try combination rom and Change to INS on combination rom again. Something went wrong in that step.

How you extracted OMC zip?

When cache.img dragged onto imgRePackerRK the generated file should be cache.img.iso zip file (YouTube video also shows a cache.img.ext4.iso zip). But there was a cache.img.img file along with a cache.img.cfg file.

I noticed the Imgextractor is not seen in the OMC extract folder. It's in bin folder. Moving it to the OMC extract folder also didn't work.

Combination rom BL6 didn't allow to change default CSC

Try combination rom and Change to INS on combination rom again. Something went wrong in that step.

Hi,

I tried with BL6 combination rom, the factory binary didn't allow me to change XAA which is default; I tried with other versions of Combination file which is not allowing me to flash as they are BL5 & BL4 respectively.

So stuck with having DBT/DBT/XAA which is default setting available in sales_code.dat of sec_omc.zip shared on post# 510

If it doesn't let you flash BL5 CSC zip on BL6 combination rom.. You may need to wait till BL6 comes out for exynos version.
I hope you tried flashing CSC zip on combo firmware.

My Snapdragon S8+ works perfectly for Airtel VoLTE here in Chennai.
I used this S8+ Combination ROM for V7 Bootloader.

If the sec_omc.zip posted by nimms wasn’t working then try to extract it from Note 8 INS Firmware (SM-N950F) CSC.
