That zip can't be flashed via odin

If you can,t use adb sideload, store it on microsd or internal storage after booting into OS.. then boot to recovery and choose apply update from storage. (Not tested that method though)
[Samsung Galaxy S8+ Guides, News, & Discussion] nimms:
Better boot once.. no need to setup though.

If force closing.. flash AP file only via odin.
[Samsung Galaxy S8+ Guides, News, & Discussion] chetan180:
i flashed i got force closes flashed clean then it worked but i got some btc csc again flashed got blank no csc just //Xac then again adb got xeu. i dont get ins in software info

all this proces was done with jio sim inserted my is s8 i tired both ur zip s8+ and s8 same results
[Samsung Galaxy S8+ Guides, News, & Discussion] nimms:
Another guy kept getting DBT

If you get one of these CSC, that means csc is changed in the phone.

Now phone will have OXM Multi-CSC, which include the following CSC's:

ACR AFG AFR ARO ATO AUT BGL BNG BRI BTC BTU CAC CAM CEL CHO COO DBT DKR ECT EGY EON ETL EUR GLB ILO INS ITV KSA LAO LUX LYS MID MM1 MWD MYM NEE NPL ORX PAK PCL PHE PHN PTR ROM SEB SEE SEK SER SIN SKZ SLK SMA STH THL THR TMC TPA TPH TTT TUN TUR WTL XEF XEH XEO XEU XFA XFE XME XSG XSP XTC XXV ZTO

So, relevant CSC should kick in solely based on SIM.

Not sure why INS is active for you guys.

If you want you may check phone info app.. it should list all CSC stored in phone.

finnalyy i did it perfect volte on my sm-g950u1 all thanks to [MENTION=7369152]anarasgarli[/MENTION] for providing me v3 combination file (https://androidfilehost.com/?fid=890278863836283758 )

and this hero [MENTION=650462]nimms[/MENTION] for the zip..

i tried followed from 1st post but it ways installed dbt csc. so i tried the v3 combination file provided by [MENTION=7369152]anarasgarli[/MENTION] and installed it then flashed the zip provided by [MENTION=650462]nimms[/MENTION] and then used

*#243203855# and installed INS CSC and echo "INS" > /efs/imei/mps_code.dat . So that my csc doesn't change to dbt again. but when i flashed stock u1 it changed. so again i adb zip and guess what INS CSC successfully installed. VOLTE icon didn't shows up for around 5 mins i tried called from my other phone to jio number but no success but after sometime it showd up may it need to register the device or so i dont know.

any1 whos unsuccessful should try via combination :fingers-crossed::cool:

thanks [MENTION=650462]nimms[/MENTION] and [MENTION=7369152]anarasgarli[/MENTION] i am just ****king happy

Glad u succeeded.

Am trying to do my method on another S8+ of ATT, it's always taking DBT. Sprint version took INS on the first go, no issues. I'll see if i can find v4 combo for 955U.. if you happen to find a link, post here pls.

I knew abt combo firmware method, but always thought it was only for changing USA variant CSC.. (did that for SPR to TMB). will try INS if i find V4 combo firm.

Only the BL number needs to match. (4th number from last that is N950U1UES4CRE1

This is your combo firmware https://androidfilehost.com/?fid=890278863836286378

Your stock fw https://updato.com/firmware-archive-select-model?record=DEA65CA860B311E89F15FA163EE8F90B

It's linked on first post already.

Start with U1 version fw if available, Don't go with TMB version (ACG is another carrier version without bloat)

Goodluck.

E: signature verification failed

Kindly help.

[Samsung Galaxy S8+ Guides, News, & Discussion] nimms:
That means the file was modified. Either you are using another file or you did something to the file you downloaded(adding or deleting stuff). Samsung signature gets void on modifying..

Or you have a corrupted download. Download again.
[Samsung Galaxy S8+ Guides, News, & Discussion] :
I tried both the files you specified in post #1, i.e.,

========

Then during part 2, instead of "Add CSC Systemroot" file, use the modified file with India and XAA-USA CSC

This will flash INS CSC along with XAA CSC. This zip was made by [MENTION=1949695]jrkruse[/MENTION] for US carriers... I've just added INS CSC to it and removed other US carriers stuff.

Or.. If you just want Indian CSC Use this file (no XAA) https://drive.google.com/open?id=0B-...FhFR2NtRHc3ajA

=========

And a noob like me cannot modify the file. Is there some other file I should use as CSC ?

My phone is snapdragon S8 on BL4

Does the phone need to be rooted ? I assumed no whilst reading the new instructions (of jul 10)
[Samsung Galaxy S8+ Guides, News, & Discussion] :
I just re-read all the instructions again and sure enough, I did all and didn't miss any step or did it wrong.

By any chance, does the foll. step hold true for USA snapdragon s8 or needs any changes ?

16) Type in echo "INS" > /efs/imei/mps_code.dat (Please make note of the space between " and > and /)

You won't get any confirmation.

Also, I used the stock CSC in foll. step. Is that correct?
