Yes. Oreo is not yet released in India. I have flashed the UK version, which I have provided in original post and flashed India CSC. JioVolte works perfectly.

You can only flash bootloader 3 version files (4th number from right in the version number)
Just sideload the Indian CSC as shown in the link just above your post. (Should work with exynos too)

950w/u doesn't have OEM unlock. These variants have locked bootloader's and therefore can't have TWRP installed. You would know this if you searched. It's only been discussed 1,00,000+ times

ok, why do they post a TWRP for 64bit - Qualcomm Snapdragon 835 MSM8998 (10nm) then? in the link i added in my post above?
and G950W is 64bit - Qualcomm Snapdragon 835 MSM8998 (10nm) as well.
ALso I do see OEM unlock option if I flash COMBINATION FILE, so can I do something else to root?
Thankyou

This TWRP is for Chinese versions that have an unlocked bootloader

It has been discussed a zillion times.. The only thing I can't find is, why?? Why was there a root available for 7.0, but that changed for 8.0?? It won't help achieving root on my G950w, but it just may help me sleep at night.. lol

Because the combination file has a exploitable permissive boot img. Stock does not. Also we only have a 7.0 combination file if all of you look in history the combination released is that of only equal to what the device was released with. In our case 7.0 we will never see a 8.0 combo to root with.
The oem unlock option in combo is only for bypassing frp nothing more. We have studied this quite well
There is a s8 snapdragon Chinese variant which are unlockable unlike our U and W models.
At current there is no root for any bootloader of our versions on reg s8 U or W passed revision 2. Hope this helps to clear up a bit on confusion

Also thread moved to q&a

help my s7
Hi, Eric here, I read your thread about frp lock bypass about the samsung S7 (link is: https://forum.xda-developers.com/galaxy-s7/how-to/g930f-frp-unlock-helps-99-g930f-t3791424), and then I downloaded the rar files in this google drive address: https://drive.google.com/file/d/1do9rJ7NlJhPq3esLG7_HLxxUOLKD9PIr/view
when I try to unzip the files, I found the password was not correct (in the readme.txt, the password is: http://zipansion.com/hcsV). I really wonder whether you can check it and send the right password to me if possible, my email address is [email protected]
It will be really appreciated. Thanks a lot.

Does anyone have the link of Nougat 7.0 for SM-G935FD with binary 3 code...??? I can only find binary 2 and 1 but not 3 after days of searching on net...The firmware must be (G935FXXU1DQL8_G935FSEB1DQL8_SEB) XXU3, not 1 or 2...
Kindly share...it will be life saving....

Once you upgrade to Oreo, there's no downgrading to Nougat FW without using a custom ROM

Unfortunately if your on Oreo you won't be able to downgrade to nougat. Depending on the bootloader version number you can not even downgrade to an early version of Oreo either.
Bootloader version number is the 5th number from the right of the file name that you downloaded from sammobile. Binary 2 device 4 is telling you that your current bootloader version is 4 and you are trying to flash a version with bootloader ver 2.
Eg: G950FXXU4CRKG is a name of a file that you would download from sammobile. The number 4 ( 5th from right ) is the bootloader version number. So you can only flash with a BL 4 or higher and not lower ( ie: 3,2 or 1 )

Flash the full Oreo firmware without the BL tab, then you will be downgrading to Oreo but you will still keep the Pie bootloader.
Also if you do want to downgrade the bootloader I found this thread: https://forum.xda-developers.com/galaxy-s8/how-to/guide-skipping-kg-prenormal-oneui-t3911862/amp/

No, I have not tried it but I thought it might work. Try downgrading the bootloader via this method https://forum.xda-developers.com/galaxy-s8/how-to/guide-skipping-kg-prenormal-oneui-t3911862
I think you can also get heimdall on Windows
Edit: I found the heimdall download page here: https://glassechidna.com.au/heimdall/
If that doesn't work I also found this thread about downgrading the bootloader with combo firmware: https://forum.xda-developers.com/galaxy-s8/help/method-to-downgrade-galaxy-s8-to-oreo-t3946240/amp/ You just have to find a combo firmware with the same binary version as your current firmware.
Downgrading the bootloader is really hard on Samsung devices if possible at all

Your device is on a bit 7 bootloader. The firmware you are trying to flash is a revision 3. You cannot downgrade your revision. 5th digit from far right end in firmware is your software revision

Same as post as above yours check all the Android 8 firmwares if they are the same bit number as Android 9 then yes. If not. No

so in my case I have to find a custom android 8 rom with bit 7?

and if I put a custom rom with a lower rev bit can I downgrade?
having rooted and having twrp?

if it has knox, most likely not

[QUOTE = "avipars, post: 84174127, member: 7551187"]
se ha knox, molto probabilmente no
