Help on updating to Nougat with signal problems - Samsung Galaxy S7 Edge Questions and Answers

Hey guys, i am looking for some help on how to upgrade my rooted s7 edge from MM to Nougat.
First of all let me tell you that I bought the phone used and rooted, it worked perfectly for some time until one day it had the Custom Binary blocked by FRP error. I tried to fix it by myself flashing a new rom. Everything worked fine except for the Signal and Data. I didn’t have any. I couldn’t fix it so I went with a guy that repairs these things. Nowdays I have the phone working on MM, but I would love to have Nougat.
I don’t know exactly what he did to make it work, I just noticed the phone has another IMEI and SuperSU with ADB Shell on it.
The problem is that the man told me I cannot update to Nougat or the “fix” he did would stop working. I want to know if there is a way to do it because I want to have the latest update.

SM-G870A Failing to Update Past 4.4.2

Hey everyone!
I've got an interesting predicament here. A little back story: a while back I installed TowelRoot, and then Xposed Framework. Everything was kosher until I got an OTA update (I believe the NG3 update) and it killed the root. No problem, I'm fine without root. But now that Lollipop has come out, I want to update but can't. My buddy applied the same root, but did not do Xposed. The difference between our phones after that OTA update: mine says "Custom" with an unlocked padlock at the Samsung boot screen; his does not.
I read in another thread that someone took their phone to Best Buy and the guys at the Samsung booth were able to fix the problem because they can pull updates and apply them via USB. So we went there yesterday and they had no problem getting Lollipop on my buddy's S5 Active. Mine, however, would not take the update. The Samsung S.M.A.R.T. tool they use on the PC was saying that "my device is running an unauthorized operating system", even though I have never flashed a custom ROM.
When I go into download mode, the Knox flag does not appear to be tripped. I've also performed a clean factory reset with a data wipe and that still didn't allow me to update. Whenever I try to update, it downloads the entire 4.4.4 update (which needs to be done first, before the 5.0 update) and it starts to install, failing at 25%, without hesitation, every single time.
I've attached a couple of screenshots that I hope will help. Any ideas will be greatly appreciated.

Have you resolved this issue, if so, would you mind sharing how you did it. I've been combing the net for a few days trying to discover what is going on and your issue appears to be exactly what I am experiencing. I've read about flashing back to my stock firmware using Odin but I cannot get into download mode, when I try and get there, the phone only says "recovery reboot" in blue small font on the top of the screen and reboots.
Thanks
Ladies and gents, I apologize for abandoning this thread. I forgot exactly how I got to get the phone to update, but if I recall correctly, it had to do with me putting the phone in download mode, downloading the original firmware and using ODIN to flash it. Afterward, the "unlocked" padlock symbol disappeared and the phone was able to get the OTA update from AT&T.
I have since moved from an LG G4 to a V20 and that is what I am currently playing with. I also have a Samsung Galaxy S6 Edge (which T-Mobile replaced my G4 with when the touch screen stopped responding). I was quite stoked to find out that there is a way to root it and (seemingly) unlock the bootloader, so I'll be toying with that this weekend to see what I can do. I'd love nothing more than to just wipe that Samsung-ified Android and install a vanilla Android or CM.
Good luck to anyone who is still trying to fix this issue. Again, my apologies. I'll dig through my archives and see if I can piece together what I did to get it going again. I still have the S5 Active. Best phone by far. It's a great backup phone for when the new stuff goes kaput.

Mi a1 no network signal - please help!!!!!

Hi Devs and team,
I have no network signal (AIRTEL or IDEA) in India. (Possibly due to PIE update) No 4g, 3g or even 2g.
I will briefly explain what happened:
1. I was in Oreo November patch till 1st week of Jan 2019 and i was not upgrading to PIE update Jan patch as well, due to all the discussion on bugs and all.
2. However, one day around 8 or 9 Jan, i noticed that update has been downloaded onto my device and it was asking for a reboot to install.
3. But i was avoiding that restart as well since i was scared i would be affected by bugs.
4. Suddenly, around 13 or 14 Jan , i lost mobile signal just like that. (NOTE THAT I DID NOT RESTART MY PHONE YET)
5. I still left my phone like that for a day and there was no change in network signal. Then i thought this may be xiaomi's way of forcing me to install the pie update and then i restarted and PIE was installed.
6. But still there was no signal. Even then i waited for 1-2 days and thought that this may get resolved.
7. Finally around 16 Jan, as my phone was still not getting any signal, i went on the internet trying to search for solutions.
8. I did everything possible. DOWNGRADED from Pie to Oreo 8.0, 8.1, Nougat (Aug 2017 build), used fastboot for this process and then used even hotboot twrp for this process, rooted, then unrooted. I have done this countless times. (Maybe 10-15 times, tried various combinations) Please note that i never had any problem with my IMEI. I always had my IMEI intact during this process. But i never had my signal back. I flashed only modem firmware as well just in case. I am still searching for answers.
9. Meanwhile, i took my phone to Xiaomi service center and after checking they just said, i had to replace my Motherboard and it would cost around 8k (approx). Mind that i bought this phone for 13k. I refused and i thought i would get it checked outside.
10. I took my phone to unauthorised service center as well. Even before diagnosing my phone, he said either antenna or network IC may have been faulty. It has been 2 days and he is now saying he is not able to point out what the problem is yet.
11. It has been more than 20 days and i am without a phone. Everything else works on my phone except for the network signal.
PLEASE HELP ME. I am not able to figure out whether its a software problem or hardware.
I have read that many users have problems with signal. can someone tell me what to do.
My opinion is that maybe seamless update feature helped whatever bug is there in pie to affect my device in oreo and now, i have no signal now whatever i do.
UPDATE: I have just checked with the service center guy (unauthorised) - he says he tried everything (including replacing antenna and other stuff) except for changing network IC. He says changing network IC is risky and it may damage other components. I am not able to decide what to do.
How did you downgrade to Oreo from Pie. As of stock pie for this device, there is arb which will cause bootloops if you downgrade with the usual methods. The steps to downgrade is now more difficult.
I'm no expert, but given what you describe and what Service Center told you, it looks more like Hardware issue than anything else.
If it was software, with all the downgrades you did, you should have been able to get back to a situation where it worked. One thing though, did you try it with another SIM/Operator? SIMs can die too, and usually your operator should give you a new SIM for free or cheap, and you could as well borrow a SIM from someone else, to confirm it's really the full phone that is dead.
So your phone is most likely broken... I guess that if Service Center said you have to pay for motherboard replacement that you are out of your warranty period? Because if you're still under warranty, they should replace for free...
You sure your Sim isn't broken?
Yes to all your questions.
1) i have tried my sims in other phones (they work) and Other sims in my phone (they dont work). Tried hard reset, soft rest etc., nothing works.
2) I have downgraded as per the tutorial of downgrade in xda forums. i had no bootloop or no imei lost cases. Everytime my phone booted well with all imei's intact. I went from oreo 8.0 to pie (over OTA again after proper downgrade) and pie to oreo 8.0 oreo 8.1 nougat.
As i said, i have tried all combinations.
Request your help.
Try installing any custom rom
Can you suggest one so that i can try? Also please tell me rooting from which version would be better. Nougat or Oreo 8.1? I would prefer one which would solve my issue.
FYI: That service centre guy returned my device, saying he could not repair it.
Apart from the above, i have a doubt whether reinstalling my IMEI may kick my modem to start picking up a signal. can i do that? Can i rewrite the same IMEI again?

U can try pie based roms like Los16 , PE latest , crdroid ,etc they r stable for daily driver.
Rooting from 8.1 would be better
Don't touch IMEI for now , try installing custom ROM , if network works then stick to custom ROM and if it doesn't work then it would be a hardware issue.
Have you checked your APN, I lost mine after an update, I manually re entered all the details and all was perfect again.
Did u got your network issue solved?
I'm facing the same issue . .
