Ariza patch says not rooted in a rooted S7

Hi all,
I'm having the infamous "not registered to network" problem in a SM-G935FD so I installed a rooted ROM (King) and other rooted stock ROMs without luck, still not network.
I'm trying to use the Ariza Patch but says the phone is not rooted... bur in fact the phone is rooted and verified.
Maybe I have an old Ariza version ? Where can I get the newer ?
Some ideas to test and fix the network problem ?
IMEI seems to be clean and OK... not blacklisted, APN is in place OK... I can see the networks fine, but can't connect.
I can assure the phone works... I bought the phone with Android 6 working fine. the problem appeared after update to Android 7... seems the phone was patched, but I don't know what...
Thanks....!!!
Javier.

Same problem here.
I'm having the same problem guys..did anyone find a fix for ariza or the s7 not registering on network after imei change?

SIM Card not working after downgrade

Hey guys! yesterday I just downgraded my device(i9500) from stock lollipop to cm11 and what I realized was that the network signals were gone. Although phone is detecting sim card as I'm able to see all the saved contacts even I am not signed-in with gmail account. I tried restoring the EFS I made when I was on a custom touchwiz lollipop ROM but I think there's something wrong with that backup as that didn't work for me. I know simply flashing the firmware using ODIN would solve my problem but I haven't got internet connection these days neither time as my exams are going on. I've only got 20MB of data to use everyday. So, I can't download firmware as its size ranges in GB's.
I've installed back stock ROM but problem didn't solve. The problem isn't with IMEI as I'm able too see it. Instead of the network name on the status bar when in lock screen , I'm seeing EMERGENCY CALLS ONLY message
Please help me. Better send me the backup of EFS! Thanks in advance
Could be that your SIM tray broke and it simply coincided with the ROM flash.

OnePlus 2 VOLTE Sign Disappear

Hello Friends , I have OnePlus 2 ( oxygen OS 3.6.1) with JIO on my 1st sim slot . Many times the VOLTE icons disappears from the status bar although the signal is full on the sim and the data is working .After VOLTE icons disappears I cant make any call from the sim and I dont have any other choice than disabling the sim card and re enabling it to bring the VOLTE back which is quite frustrating . Any help on this ?
Try resetting the network settings within your sim card menu. Revert if issue persists.
Hey I already tried network resetting but nothing works
perhaps reflashing the modem firmware file of 3.6.0 or 3.6.1 will solve your issue. Link is in the lineage OS 15 thread. Search for the keywords you'll get it. If you don't I'll link.
Hey send link didn't find it plz

I am also facing this issue recently.
I Tried reflashing the OS to 3.6.0 and 3.5.6 but same issue still persists. I cleaned Data and cache too.
(Jio VOLTE is now only working in SIM1 slot. Previously it used to work in SIM2 slot too. Even after flashing to older OS, facing same issue)
No success yet.

Unique volte and data bug in all custom roms in my device.

Hey guys,
Recently I flashed nitrogen is roms by soleintic,the ROM was working flawlessly without any issues...Today I went to service centre to get my device's speaker changed.After getting my device back volte was not working while previously it was working,So I thought changing swapping the sim slots would do the work I did the same and volte was working then but my data was not getting connected it was showing some random error in ipv6 and ipv4,then I again switched the sim slots and in slot 2 the data was working but volte was not working so I thought reflashing the ROM would fix the error.I reflashed the ROM again but the error was still there...So I decided to switch ROM..so I flashed PE ROM 5 mins ago but it's showing the same error pls help me I can't understand the real problem.

In short...Volte is working in slot 1 where as data is not working in it where as data is working in slot 2 but volte is not working there....The exact thing on phone info is
Ipv4:fail(2)
Ipv6:fail(2)
HTTP client test:Failed(IoException)
Flash miui rom and then flash any custom rom. I'm not sure where it'll fix the problem but chances are high
