[Q] Dropping Calls

I have two VS980 phones that shipped to me stock with the 26a firmware. I have rooted both phones and have updated to the latest TWRP recovery. They both work as expected as long as leave them as they are. However, as soon as I install any custom ROM, they will both drop phones calls randomly.
I have tried almost every custom ROM available on this forum (Stock, CM, AOSP) and all of them will drop phones calls within a few minutes. I have also tried changing basebands and flashing my EFS backup without success. Data, Texting, Wifi, GPS everything works but no phone calls, even with full signal bars. As soon as I revert to stock, everything works like normal.
I have searched online and on the forums but I can't seem to find an answer to this. I am at a complete loss. I don't want to be stuck on the stock firmware forever. Does anyone have a suggestion?

[Q] KitKat to Lollipop - the phone is unusable (huge battery drain and sys errors)

Hi everyone,
Until recently I've been using a KitKat based ROM and I was pretty OK with how my NOTE 3 SM-9005 was performing. However, a few days ago I decided to try a Lollipop based ROM and the problems started. I had similar problems with 3 different ROMs with great reviews. My battery went, for example, from 100% to 15% in ONE HOUR while streaming from YouTube. It never did that before. Also, It sometimes gives a "system stopped responding" error or something like that (it's like the equivalent of explorer.exe crashing on Windows) and after a few seconds it starts working again. Other system apps crash as well every now and then and sometimes the phone just decides to restart by itself.
I initially used Philz recovery and after the initial errors I switched to TWRP and started from scratch. I completely wiped my system internal space before flashing and, of course, I wiped dalvik cache and cache before and after flashing the ROM. I only used recommended gapps. Also, I did not restore any system apps. I started from scratch after the installation and the problem is the same.
To be more exact, I tries flashing so far the following ROMS, experiencing more or less the same problems on each:
temasek's UNOFFICIAL CM12.1
AryaMod V5.4 TW Lollipop Official BOB6
BlissPop 3.5 Unofficial
I also tried the Dirty Unicorns v9.4 ROM from the Original Android Development section but this one went on a reboot loop initially after the first restart so it never really even installed.
At this point I believe I might have done something that I should't have, but it seems strange because this is not the first time I am flashing a new ROM and I never had problems in the past. Also, my NOTE 3 SM-9500 did not have any problem on my previous KitKat ROM. Did I miss something? Should I have used another kernel? If I understood correctly, the ROMs come with a recommended kernel already. If this is not the problem, what could it be? Should I have done any additional thing before flashing a Lolipop ROM after using a KitKat ROM?
I now installed an app for trying to find out what exactly drains my battery but this is not the only problem. The system itself is really unstable.
I would really appreciate some help, suggestions, or opinions. I really don't know what else should I be doing at this point.
Thanks a lot!

Apparently is the media server eating all that battery (currently 68%).
I will format the SD card hoping this fixes the issue.....but could this have something to do with the system error and, sometimes, restarts?

Well I really don't know what to say! A lot of people report battery problems on 5.0 just because they didn't wipe the phone while coming from KK! But you did, so that's no go. Battery life on LP is much better than KK for me, at least 20% better if not more. And I didn't face any system crashing issues either! Don't really know what's going on with you mate.

Someone suggested that maybe I shoud update the bootloader and modem to a Lollipop version but I really couldn't find any info on how to do that.
Formatting the SD card just slightly reduced the battery drain. The phone is still discharging like crazy. Any suggestion on how to update the bootloader and modem?
Thank you.

NF910F Random reboots/power failure

Good evening, just a quick ( I hope) question
Recently came from stock rooted 5.1.1 to a 6 rom.
Ever since then my phone lags then shuts down, sometimes reboots sometimes not. I put this down to the rom. However it does it on every single one I have tried. It is also doing it on stock firmware flashed via odin and rooted via cf auto root, any ideas? Hardware issue? faulty bl? Currently on the unofficial cm12 (5.1.1) but still having the same issue though not as badly. Any help would be appreciated.
Also, youtube is how shall I say, funky. Some videos play fine, others say network error. This is on both wifi and 4g. Again, only recently is it doing this which makes me think software rather than hardware issues

Phone reboots to TWRP automatically when powered on or offline charging

Hi,
For some reason my phone is booting to TWRP every time I try to Power On the phone or charge my phone while its turned off. I am facing this for these couple of weeks. I don't think I did any sort of change to device. It started to happen all of the sudden. The problem started on Stock TouchWiz 5.0. So I thought maybe flashing custom rom may fix it. So I tried to flash AospExtended ROM and the problem is still not gone. On top of it the phone also reboots randomly and boots to recovery. The frequency of the reboots on Stock TW was low but in Custom ROM it is frequent. I didn't tried flashing stock firmware yet for now because I don't have access to my PC yet.
Please can anyone help me with the problem. My phone is SM-G530H running on XCU1BPB1 Firmware.
Thanks

Data not working/painfully slow after flashing custom rom. I'm at a loss

I had latest stock firmware and everything was working fine except it wasn't getting any updates so I decided to flash Linneage. I followed instructions, made sure to flash the copy-file on both slots etc. Everhything seemed fine untill I left my home and didn't have access to wifi, then I noticed that data didn't want to work. It showed having 4g connection (full strength) but it was so slow that I couldn't even check speed because the homepage barely load. There was a connection but since it was so slow I received timeouts almost everything I tried. I also noticed that bluetooth didn't work. It would connect/disconnect every 3 seconds from my bt headset. This was "fixed" by disable google on my phone. Very strange.
I thought It might have to do with Linneage so I tried Pixel experience. Exact same problem there.
I thought maybe the linneage files I flashed to both slots were bad so I reflashed stock rom. Now I have the same problem with stock rom as well. I eventually used the MSM tool and reflashed the latest stock firmware, locking the bootloader and all that. Still having the same problems. These two problems were non existant before any of this.
I've tried my sim in a different phone, even made sure the apns are the exact same on my working phone and my op6t.
Is there any other way to make sure the phone is completely factory restored other than MSM tool? Now I'm running stock oxygen, no root, locked bootloader etc but the problem persists. What is my next step to try?
