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.
I have the same problem, were you able to resolve yours?
I've same problem, i've got signal, full, but emergancy call only. Ariza patch solve your problem dude?
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?

Nokia 6(TA-1000) cellular network not work after Android Oreo

I just upgrade my Nokia 6(TA-1000) to official Android 8.0.0 (Oreo).
Then my Cellular network won't work anymore.
I live in Hong Kong, using sim card service "CMHK".
I think it is LTE/WCDMA mode.
Tried "*#*#4636#*#*" and changing the settings.
But the connection always shown IPv4: Failed(2)
The phone notification show it is connected and running 3G network.
But the upload/download speed is always 0KB/s.
Reset to factory setting already.
Before upgrade Android everything work fine.
Anyone have the same problems?
Now, what can i do....?
It seems I can't even downgrade my Android.
Only, have to wait for next update and hope it will fixed?
I think i am screwed.

I already do factory reset on System Settings.

No, there is a lot difference between system reset(soft reset) and recovery reset (hard reset)
Try it, may be it solve your problem

Have you tried other SIM cards, whether you work in your cell phone! Tried to register your network operator service in the settings! Set preferred network ~

I use official update.
All firmware should be correct?
BTW, I get a new sim card from ISP but cellular network still not working.
Also, tried both sim card slot 1 and slot 2 nothing work.
May be new system not compatible with my SIM card service only which is "CMHK" aka "中國移動香港".
Hope next update will fix that...

NOKIA 6

i updated my nokia 6 TA-1000 to oreo update.
i faced many issues like lte not working.
in battery saver mode launcher is stopping suddenly.

i didnt get network signals correctly.
Then i tried to hard reset my mobile ,after complete reset and after rebooting it stopped at language selection,i clicked lets go many times but it is not working .it got stucked there.
is there anyway to get rid of it.i asked for nokia chat support but they are asking me to take mobile to nearest service center.
if there is any solution please guide me with it .thank you in advance.
I just turn off the cellular network yesterday.
After I wake up from bed, my phone Google service can not connect from wifi(can't use email, Google store).
BUT! After reinsert my sim card and turn back on cellular network, everything working now.
Both 4G cellular and Google service all good.
May be some part of the network is cached.
So, if you encounter this problem just turn off cellular network and wait.

It seems that, the old slot 1 cached your sim card.
So, you change to slot 2 work, but you can't use SD card.
And I found that if you wait a long time the cache will clear.
You can try to insert sim card back to slot 1 after 1-2 days.

The only option was left to flash stock firmware, but as it updated to oreo, its bootloader has also been updated so I will suggest you to wait for official oreo firmware to release, please don't try to downgrade your device for now, it can brick your device very badly, keep patience, if any solution will come out, we will definitely tell you

Yes, I got it fixed...
1) Just turn off your cellular network.
2) Wait for 1-2 days.
3) Turn on your cellular network again, it should work.
How can I off cellular network. Will keeping it in flight mode helps?

Thank you for raising this question. My phone got the same problem. I am just wondering if I should send it to maintenance center but I guess they will just do reset.
And by saying "turn off cellular network and wait for 1-2 days", do you mean by just turning off the data usage, or turning it to flight mode/ turning the phone.

After installing OTA 8.0 update My cellular network has stopped working.

I currently use my s7 flet G935FD in Brazil. The mobile did not perform updates via OTA since I acquired it (Android 6.0), I decided to install the 7.0 update by Odin and there were no problems. When performing the update android enabled an OTA update for Android 8.0 Oreo, I performed the automatic installation and in conclusion I noticed that the operator's cellular network had stopped working (when the problem started). I searched in various places about what happened, unfortunately without success and had considered some problem related to the IMEI of the device. When checking the IMEI situation there was no restriction and the mobile phone only recognizes 1 operator network. It has been 4 days since this occurred and has already detected more than 1 different operator, but always only 1 network at a time. I ask for help from someone who understands what might have happened when installing the OTA update and the network has stopped working, the phone is only on an emergency call. If possible tell me a step by step to solve the problem, I had flash of several roms of old handsets and it is the first time that I come across this type of problem. Thank you in advance and I apologize for bad english.

[Question] Samsung S8+ G955F sim 1 not allowed.

Hello, recently I bought and repaired an S8+ which is still in Nougat. Silly me not testing all basic function after the repair.
I hurriedly update the phone to Pie. Last night, i put in the simcard in slot 1 and it function well in 4g connection.
Here is the problem, whenever the phone disconnected from 4g and connecting to 3g/2g connection, there is notification "Sim 1 not allowed". After discovering that problem, i proceed testing sim 2 and its normal (can even toggle between 4g and 3g/2g).
I tried resetting the phone, but the problem persists.
Atm, i thinking of flashing stock rom, maybe something was corrupted during OTA update.
How can i fix this? Or anyone have an explanation to this problem.
Thanks!
