Volte works on his U FW?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] SinisterDev:
Well, much to my dismay, this did not work for me either! Im about ready to just ask AT&T to send me a new phone. I do thank you for looking into this issue and trying to help resolve it. Perhaps there is something more I have to do in order to restore functionality again?

I followed your instructions to the key. Double checked everything. Changed the .xml ,saved it, reset my phone just in case,and the problem still persists. I went back into the folder to check the xml and the changes stuck, but still no good...

I dont know if It will help at all, but I did notice a second .xml in that same folder called ims_nv_ATT.xml . I took a peek inside of it and noticed that the text was almost identical to what you posted in your fix , except VOLTE_Enabled, and LVC_Enabled were set to "0" . So I tried changing them to "1" like you suggested , just to test, but that didnt fix it either :crying:
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] SinisterDev:
Huzzah! I spoke too soon! Changing the second xml did the trick! For some reason the change didn't happen right away. After the second time restarting, the functions still didn't return. After about 15 mins, the AT&T video call prompt came up and then everything started working!

Woot woot! Thank you again Najoor!

Those who flashed back to 935A, what's the order of the dialer buttons on the bottom? From left to right is it: voicemail, call, video, and Hide?

---------- Post added at 08:29 AM ---------- Previous post was at 08:27 AM ----------

I got that when I was on 935U firmware and flashed the 935A CSC file. Did you use the correct firmware files in the stock firmware thread? Make sure you use the version of ODIN that is NOT patched.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Alaris:

[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Tikerz:
Oh sorry, I thought you were trying to flash back to stock. So, in that case you do have to be using the Odin PrinceComsy version. Double check all the component files are from 935U. Like I said before, I tried to flash all the 935U files except for the CSC which I used from 935A and I got the DM-VERITY error upon boot.

Why are some people jumping ship from U back to A? Just curious as to what's going on.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Alaris:
I mostly did it to stay up to date with the security patches. Until I see that people who switched getting updates I will stay with AT&T. I also wanted to see if I could switch and get volte and everything working again.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] gtg465x:
I am sticking it out with U for now. VoLTE I don't care about because A) I don't usually browse the internet while on call B) If I do, I'm usually on Wi-Fi C) It's not like 4G / H is slow anyways. HD Voice I do miss a little, but I don't talk on the phone that much and I managed to do just fine talking on the phone without it for the past 15 years, so it's not a deal breaker. Don't really care about being a couple security updates behind for a short time as there's still almost no risk of your phone being compromised if you aren't being stupid and installing random or pirated apps from the internet. I have been following some threads of people who actually bought U devices and even they haven't received any updates yet, so at this point there is no reason to think that OTAs are broken for people who flashed the U firmware.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] najoor:
I don't remember what ODIN version I used, but I have found it doesn't matter. Either your ODIN can flash it or it cannot. If it flashes it, it seems to do it correctly with any version.

[MENTION=2737578]rob219[/MENTION] says he had better success with some odin versions than others but I tried two of the versions that he reefred to and neither worked better (or worse) than anything else. He later said in this post that version 3.1.1.2 works better for him but I am not sure if that version exists or if that is a typo. I think it is best if he just posts a CLEAR link to the odin executable files that he says fixes the volte problem instead of writing description and quoting other posts. I am very confused by his posts about this.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] wcr84:
The update just started in Europe this morning. Seems to be rolling by region/device. I suspect last Edge released will be last of the unlocked updated.

i posted a link to the thread with the odin in my first post
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
TL;DR - Jumping back because U being faster is a placebo and its still got plenty of things you cant uninstall. Also, the volte features I did end up missing. This thread is also seemingly orphaned and until all we've learned is updated by OP its causing damage to peoples phones that don't read all 60+ pages, flashing does leave damaged config that requires root to revert and its not easily reversible for all users.

I went back because there is no noticeable speed or performance gain which even though I don't make decisions based upon benchmarks my benchmarks were 125k+ on Antutu on 935a which lined up with my anecdotal feeling that the 935a fw was already butter. For now some things like no ability to turn off camera shutter sound and feature loss started to bother me. I asked myself if a few GB gained was really worth it when I store all major space eating files on external SD and have plenty of space left on my internal SD anyways. The answer came to no. Also, as time goes on and AT&T likely adds WiFi calling to this device I don't want to deal with full wiping and unreliable outcomes. The A firmware features are worth it to me, if you have a bunch of ATT people the clarity and speed of the call pickup are fantastic.

What's the possibility of the xml file for volte to be pushed with adb?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Tikerz:
I think the key to getting VoLTE and VideoCalling to work on 935U is the IMS registration. Unfortunately, I think AT&T controls that by device model or something so we're screwed.

The first file I changed was the ims_nv_ATT.Xml

But the features still weren't working. Then I made the same changes to ims_nv_default.Xml and after changing both ,my functions suddenly worked. Strange huh?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Skizzy034:
What xml file? We already tried others.xml.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
ims_nv_ATT.Xml this one once fixed. It's what gets it back on A..

I'm throwing in the towel for now. Too much flashing for a few GB gained, time investment for sh*t breaking if we want to go back to A isn't panning out. I'm wait and watch this project from afar hopefully mature.

[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Jbluedodge:
Someone that has knowledge on making a pushable edited ims_nv_ATT.xml file and a pushable edited ims_nv_default.Xml file. That way maybe we don't have to root and we can just use adb to push the files and have VoLTE.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Tikerz:
You need root to access the directory those files reside in.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Jbluedodge:
So even using adb, you will still need root to push them? I was able to use adb to do the adoptable storage modification without root.

You can't access the EFS without root.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Jbluedodge:
Oh okay. So I guess a pushable xml file would not be needed. I guess I'll probably switch back to the A firmware tomorrow and hope all the features come back.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
They will not. You have to root and change the XML files for vlte to re-enable on A. I spent the day doing it. Now I'm running and keeping root for a bit. Gonna end up back on A.

How did you get rid of the annoying security notification? And what did you do about the lag? I rooted then went back to stock.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
I flashed a zip from the Verizon thread, it runs some scripts for CPU governor and reduces lag(not perfect). Got rid of the volte icon w a custom apk and then disabled the security log apk that causes the security nag. Gonna stick on root a few days and see.

Remove volte icon - Place THIS in ROOT>SYSTEM>APP>IMSSERVICE. Be sure you set it as RW to be able to copy ontop of the file sitting there.

Flash THIS in Flashfire for general lag reduction(as i said it's not perfect,do not use any other kernel controller, uninstall if you have one before you install this with flashfire and reboot)

Sorry i didn't link you to the threads they came from- if you need later i can find but i have these on my system and 100 tabs open from reading a million posts and don't feel like reading anymore to find the sources.

Has anyone flashed to stock, did the xml fix, and then re flashed back to stock a couple more times to see if the fix sticks permanently?

I guess what I'm wondering is, if flashing back to stock, even from a stock 935A FW, would the xml fix need to be done every time or is it fixed after the first time?

Hey guys! Check out this thread! These fixes are working wonderfully! This guy put alot of work into making it simple to fix many of the eng root issues. http://xdaforums.com/verizon-galaxy...es-root-install-xposed-unroot-t3411039/page74

I had originally unrooted because my phone was performing terribly after root when it was first developed. Even after changing the governor and performing other recommended tweaks. But I had to root again to tweak the xml after going from the U firmware back to A firmware. So I figured before unrooting Id look into what progress has been made on improving the performance of the eng root since then. More people interested in root need to check this out!

This guide was VERY easy to follow and fixes soo many issues. My phone is working like it was on stock AT&T firmware now. Smooth and stable, cpu isn't getting hot so far!
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] byte9:
Yep, that's where the zip I posted above came from 1 page back. It's still not perfect even with his flashable and WiFi still doesn't stick passwords. It's just a mess. Too many fixes and hopes. I'm still rooted waiting to see how it matures but let's not mislead anybody saying its stock speed. I went through that entire thread, flashed the fixes and its better, slightly better than usable. For root that'll do for now.

Well, it seemed to fix all the issues I was having previously when rooted. My phone has been operating smoothly, the cpu isn't getting too hot anymore. No weird lag spikes.

[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Jbluedodge:
I think to fix the WiFi password issue, you use a build prop editor, search for ro.secure, select ro.secure.support, change the value to false and click save. Of course when it ask for root permission click grant.

Ask yourself this are you willing to lose Enhanced LTE and Video Call and both Firmware performance the same, another thing is are you willing to just gain 2gb more in internal storage cause since G935U doesn't have AT&T bloatware all you gain is 2gb extra of internal storage, so are you willing to sacrifice all that, some will but most won't, so is it worth your while, Hope this helps answering your question.
