Phone can't detect sim card after flashing, no IMEI - Samsung Galaxy S7 Questions and Answers

I flashed a root rom, didn't work. Flashed a stock rom, phone turned on normally. All functions are working fine except that no sim card can be detected and the phone's IMEI is gone! During flashing of stock rom I didn't flash BL as that caused errors.
I used a 7.0 stock rom, should I use 6.01 instead?
Edit: Camera and home button seems to have issues too. Can't use the home button without opening camera, and camera doesn't work.

Is your S7 fake?
Where did you get the stock rom from?
Did you write down or remember the "Build Number" before you flash your phone?
If Yes, redownload the stock rom that with the same "Build Number" and reflash with the latest Odin.
Also, make sure to enable USB debugging and OEM unlock.
When You use odin to flash a stock rom to your phone, make sure it look something like this on your computer before you click Start:

[Q] WIFI Toggle not working

I tried to flash a CM11 rom and had some boot loop issues.
Tried to wipe everything and reinstalling using both TWRP, CWM and Philz touch. Nothing Worked.
Rolled back to Stock ROM (4.4.3) and got my phone back, however: My WIFI toggle wouldn't work.
Don't know what is happening and can't find a way to make it work again. Can someone help me out over there?

Is it normal to have an Unavailable MAC address?

Is there any idea on how to fix this, i have same issue here, after restore/unbrick Moto G GPe 4.4.4.

Unable to root with latest stock flash

A little background
I accidentally disabled and re-enabled developer options and forgot to reactivate oem unlock. when I swapped out my sim card for a trip, it generated the "custom binary blocked by FRP"
I went ahead and solved it by flashing a stock rom.
Here's where my main problem happened :
I can't seem to root the device and I can't seem to be able to flash a custom rom over it either.
When I attempted to root via cf auto root or Magisk (via Odin), the phone will load up then I get a screen saying "Verification Failed" + a notice that the only way to fix it is to do a factory reset.
I just reflash the stock rom back but lose root.
I also tried doing a dirty flash of SuperStock and while the initial install was successful, it won't load up. I left it alone for an hour and nothing happened.
I don't know what else I can do to atleast just root the phone so I can use titanium backup to backup all my app data.
I'm assuming that when I flashed the stock unrooted rom, it went ahead and encrypted my internal storage which is the issue I'm having right now.
I would love to get this sorted out.
I've attached a ss of the build info
Thanks!

Need help removing the Custom ROM FRP (SM-G930W8)

I need help removing the custom ROM FRP lock in my S7 but i don't know the CSC or what carrier it was originally form as i got it used, anyone who can help would be in my debt. i should note that the Smart Switch method doesn't work as it wont connect properly via USB.
I am open to any and all solutions and/or alternatives.
would it be easier to just send it in or buy a octoplus stick?
EDIT: I don't have anything important on it so I'm fine if i have to reformat or wipe the PIT
EDIT2: I think it may have been Bell but I'm not 100% sure

I'm not sure what do you mean, you mean:
You have a custom ROM that has a FRP Lock? if so, then you probably have TWRP, which makes it super easy to solve!
You have a stock ROM, but you tried to play with OS probes and ended up with an error regards uncertified modifications? Then it's also easy to solve, check the internet, there are guaranteed ways of passing FRP even on Binary 8 Firmware.
The 2nd methods works if you can actually boot into system*
You may check the recovery and the logs to find what Firmware is on your phone, and which CSC/PDA it has, and yes, the stock recovery has the ability to show you them.

Everytime i tried to root my SM-207M (samsung a20s) i got secure check fail

At this point idk what to do. I guess i unlocked the bootloader properly (since where i've read about it said that if the OEM button in developer options is grey it means it's properly unlocked) and also downloaded the right fimware from both frija and samsung fimware downloader. I double checked if the fimware was right by typing *#1234# in the dialer and seeing the fimware details, all was correct. Patched the .tar trought magisk properly, actually i followed this tutorial from here (bc it seemed the same for all samsung models), but everytime i flash the archives with odin, after it's done i get "secure check fail: recovery.img" (if i selected recovery in magisk) or "secure check fail: boot.img" (if i didn't selected recovery)
Idk what to do. I'm a noob but i've rooted other phones before and i'm lost rn bc i'm doing everything that it was suposed for me to do. Help please?

Assuming you're using a Windows PC and Odin.
Run Odin as administrator.
You'll need the exact OEM Samsung firmware for your device. Good thing you included the variant code of your firmware in your original post.
Here is one place you can find the file to download https://www.galaxyfirmware.com/model/SM-A127F/
After downloading, extract the zip. A few "tar.md5" files will be inside.
Using instructions from here, flash the original firmware onto your phone.
After reboot, the phone might restart a few times and launch into recovery. If it does, then select "format data" in recovery and reboot.
Phone should be back to factory ready for you to brick again.
Also if you want to try rooting again use patched magsisk
