No connection after root - Samsung Galaxy S7 Questions and Answers

So I bought the Galaxy S7 today from Boost Mobile and it was activated and working. I went to root it and now I cant get any sort of connection back. I've been on the phone with Boost Mobile trying everything and I still cant get it to work. At one point it was in a loop where everytime you reset the phone, it would try to activate and then randomly reboot. I keep trying to activate the phone through settings and thats not working either. Does anyone have any ideas on what I can do?

Is your IMEI still ok?

Bought Sprint Touch Pro and Internet not working... help?

ok heres the story....
i bought a used mint condition touch pro and activated on sprint online and the touch pro is running fine but the net wasnt working... i took it to sprint and they told me that the inner workings of the usb port were damaged and it was hard to communicate with the device via usb cable so they could not do their stuff, i though it was BS cuz it charges and connects to activesync as well as flash drive just fine at home till i tried to unlock the device which always gave me communication errors... i can do it via sd card no problem as i did and flashed energyrom just now but i still cant connect to the web and they said theres nothing that can be done about on their part that and i would have to call insurance and shell out 100 bucks for another one cuz the in-store warranty did not cover that. But i dont think that the usb port (which is fine IMO BTW) has anything to do with the net not working rite?
they told me do dial ##DATA# and restore the profile, soft reset and then attempt to update the profile via settings but it fails every time with error code 67 / incorrect username/password... i flashed to stock rom before this and hard resetted BTW and no dice... i think it may be a hardware problem cuz everytime i try to update my settings and fails, the username of the previous owner always goes back and thats maybe whats going on. but to no avail the device updates with my info...
the USB port damage that they mentioned was to connect the device to a diagnostic machine and since its damaged it cant connect to diagnose the problem so i guess im stuck then...
What do you think? if i can get my web working i would most likely keep it since i can flash via sd no problem and switch it for a pro2 easier than paying for it. i tried to update profile and prl but they always fail... i always get a incorrect username/password error 067
if anyone can help me get my net workin again i would fully thankful, where can i manually get my sprint internet settings?? cuz the DCD carrier cab and PRL update cab did not work for me...
i have noticed that when i go to device info. the sprint username isnt mine so i guess that would be the problem, i know what mine is but where do i change it? and what about password and anything else required for the sprint internet sevice to work??

No service [SM-920I]

I can't get a signal on my phone. It keeps showing the "emergency calls only" message. When I try to call someone, it shows an error message: "network not registered".
Weird thing is, it was working flawlessly a few hours ago. I didn't mod it, nothing is different. I just charged it and rebooted.
I tried toggling airplane mode on/off, factory reseting, and it didn't fix my problem. My IMEI shows up correctly on settings, and the phone is being used in the same region I bought it.
OBS: If I put the sim card on another phone, it works. When i put it back on the s6, it keeps working until i reboot it, and after that it doesnt register on the carrier network anymore.
Anyone can help me with this?
No one?
I've exhausted all my known options! I can't keep a phone that can't even be turned off. If the phone freezes, that means I'll not have a signal until i can find another phone to put my sim on, and then back again on mine...
I'd really appreciate some help, since support where I live is crappy and chances are that i'll have to take the loss on the defective phone if I can't fix it.
Went to the carrier, tried other sims, even other carriers sims. Still nothing.
You can't get warranty from who you bought it from or else samsung? it sounds like a defect somewhere, if you are lucky it could just be the simcard tray but else it is something inside the phone

hands free activation problem after root

So i got this sprint galaxy s7 and figured i'd try to root it. All was going well till the activation thing came up and it just wont work. It would constantly retry to connect but that failed so then it went to a manual activation thing so i figured it was fine. Well after the manual activation setup thing is over the phone reboots and i go through it all over again. Not sure if i can flash the stock firmware since i had factory reset it and usb debugging is obviously no longer turned on and i also can't even get to it. If anyone has any answers i'm up to try them out.
I've already tried bypassing the setup wizard but that doesn't seem to work.
EDIT:
can't even find any stock firmwares because i guess host sites have a 2 gig limit to downalods and i'd have to get premium.

Mobile Networks missing

it is my uncle's phone
SM-G920F Galaxy S6 (G20FXXU5DQA2)
flashed back to stock and everything is 100% stock but the mobile networks in settings is missing and the sim cards wont work, it detects them being inserted but doesnt seem to connect.
Please help, couldn't find anything
Messing around with mobile data gives "insert sim card"
tried to factory reset from recovery, clearing the cache and reset from the Smart Switch desktop software.
Could possibly be an issue with the sim card slot, does the phone show a valid imei number?

100% hw, faulty SIM reader, cold solder, or something else on motherboard.
Try to ask in Samsung authorised repair center, maybe if you are lucky like me, factory warranty would be accepted.
I just told them I bought the phone second hand and it does not recognize SIM, did not go into details
force stop stuck on s6

The same thing happened to my G920P and I was stressing out looking for a solution. Finally, I figured it out myself.... I used idonne apps unlocking service awhile ago and still had their unlock app installed on my device. After trying repeatedly to no avail to unlock again I finally started looking thru the 3 dot settings and manuvered to the IOT HIDDEN SETTINGS TAB. From there I went to the "test mode menu" setting. Then to HW Test setting, down to #7 NV Rebuild All. Clicked that and let it do it's thing and all settings returned, no more stressing. Hope it works for you.

Losing phone signal

My Galaxy A01 core loses network signal, when I go to turn on mobile data it doesn't work.
When I go to make a call, a message appears saying "Not registered on the network".
I tried to register it by going into the settings, but it didn't work, I tried to format it and it didn't work either.
I have already updated the Android, I went back to an old version and it's still the same (Android 10 Go edition).
I have to keep restarting it to get it back to normal.
Can anyone help me?
