NFC won't switch on - Xperia Z2 Q&A, Help & Troubleshooting

Hey everyone, so my NFC used to work fine all the time, but I think it was since I have rooted my phone and upgraded to MM it will no longer activate. I switch it on in the settings menu or through the quick settings tile but it switches straight back off, and the NFC tests fail.
I'm thinking it might be a firmware problem or some problem from flashing, but I have terrible Internet at the moment and was hoping somebody might have an idea how to fix it without factory resetting etc..
I initially gained root on lollipop and created my own pre-rooted zip to update to MM, but I did have to use the bootloop fix. I have just upgraded again from 575 to 291 with my own pre-rooted zip hoping that might fix it, but same problem and I had to use bootloop fix again.. Any ideas what I might be able to do to fix it? thanks in advance!

stock wifi issue

Ok guys. I browsed through the forums for this but can only find my issue on custom Roms. My issue is with my wife's phone on the Stock Rom. I rooted her phone the other night and since then her phone has no wifi signal til a reboot then her wifi comes back in nice and strong.
Is this a known root issue? Her phone is on 4.0.1, which I believe is the latest firmware for this phone to date. The only thing I did after rooting was, of course, install apps necessary for root and flashed a security program. Nothing else.

NFC on deodexed stock 5.0.2

Hi all
I've succesfully deodexed my stock rooted 5.0.2 (AOE3) system on my s6-g925f with the help of ultimatewaffel, _alexandr and svadev's deodexing tool
SO I'm up and running with everything working after fixes and patches of ultimatewaffel
Only issue left is NFC, which if I use the toggle stays semi-yellow and of course nothing is activated
Also if I go throught the settings menu, every option is greyed-out and disabled
If it's a matter of kernel, that is stock, then it's ok I won't do anything, but if it's something else....
Please don't start to tell me to update to 5.1.1 because I use sammy smart view app to stream my tv's contecnt on my phone display and this is not working on 5.1.1 which needs a non-stock kernel to be rooted!! Also I have my knox intact and I've already made so many changes, so please help if you can on the NFC issue!
Thank you all
EDIT: SOLVED with help of ultimatewaffle.!!!!!
Thanks

NFC settings

Hi,
I got my P9000 yesterday and flashed the OTA 20160531 over the flashing toolkit. After that NFC settings are there. Later I flashed the OTA 20160608 as flashable zip and the NFC settings are still there. Today I saw that the NFC settings are gone. Does anyone know about this issue or has a fix for it? Using the stock rom.
Thanks for you help
Hi, i habe exactly the same problem. Updating to build 150715 hasnt helped. Any ideas what to do to make NFC appear back again?
I had the same issue when updating my rom. After some days I rebooted the device and suddenly the NFC settings where back. I have no Idea if the reboot helped or anything else.
If you really need NFC you can also try flashing a custom rom such as Eragon V3 (my recommendation) or Aerom V5.

[Problem][OP2][OOS 3.1.0] Random reboots

Hi to everyone!
I have a problem to share because I hope anyone can help me to fix it.
My OnePlus 2 with the stock ROM of OxygenOS 3.1.0 (never unlocked bootloader or installed custom roms... always with the original system) has a problem: since 2 weeks he started rebooting randomly... it may happen from 1 up to 3 times a day (in my situation). These reboots are not caused by apps I think because a lot of them happens when the phone is with screen looked and it is in my poket or on the table (on charge and withoutcharge also, is indifferent). Sometimes happened also while using it (it could be a browsing session, a photo.... it's random!).
I also noticed that before the restart the phone freezes, expecially when its screen is turned off, you can't turn it on and all gestures or phisical key (also the fingerprint) doesn't work.
I noticed the first time that the phone rebooted exactly for the fingerprint sensor, because I tryed to unlock it and it said that after reboot I need to first insert the unlock sequence.
I tried (in this oreder):
- to make a cache and data wipe from recovery (with no result);
- to make an hard reset from the recory installed into the phone (with no result);
- to make another FULL wipe and reinstall the OxygenOS from the zip installer on the official download section of the oneplus website (with no result).
Now, I beg to all of you to help me if you have any suggestion or know a fix for this problem.
Thanks in advance to all people that will help me
Hi...
U will need to upgrade to the latest oxygen os 3.5.6/3.5.6 or flash a custom ROM like cm.
In order to do that u will need to unlock bootloader and install twrp and then flash zip.
Ensure u take a nandroid backup in twrp before flashing roms
Everything can be found on google. [emoji4]
Hope it solve the problem

But the phone worked well for months... why now there is this problem? And anyway there is no update by OTA and I don't want to unlock the bootloader for an update that I have to recive by official way...

It's probably caused by a google app running in the background.
If u can get a logcat of the the device before reboot without root would have an idea.

How can I take a logcat? and anyway I don't know when the phone will reboot... and when I discover it is too late because like I said it freezes for 10-15 seconds and I can't make anything...
Well if u are looking for ota, check out this: https://forum.xda-developers.com/oneplus-2/general/hot-fix-3-5-6-oneplus-2-official-update-t3528911
since u don't want to unlock bootloader n stuff.

Oh thanks... but why I didn't recived it by OTA?
Well idk but I think it is released in some country or not quite official yet.
Tbh I'm using custom Roms so I never checked it.
As they say, it fixed random boots and use a VPN and select Germany or Canada to download the zip via ota or can manually flash in stock recovery.
I recommend the ota it's more safe.[emoji2]

[MTK] messed up mtk engineering - No service

Hello everyone,
I got a redmi note 4 yesterday. I'm living in germany and noticed that the overall network quality isn't the best, so I tried to find out if I could optimize settings within the mtk engineering mode (*#*#3646633#*#*).
However, I went to world mode and changed it from 12 to 2 by accident. Now Ihave no signal at all and I am unable to undo it. Is there a way to reset settings or will it be fixed by switching to another ROM/factory reset?
I tried to google to find a solution, but there is basically nothing helpful to find about the world mode. In fact there is basically nothing to find at all.
Any help would be appreciated. Also - if there is - I'd like to get an explanation what world mode is and what it changes.
Hi,
I believe flashing a new ROM should bring back the default settings.
I say this because I once flashed the deep sleep fix mod which removed LTE option from the menu & it was back to defaults after a clean flash with SP flash tools.
As for your network quality there is some debate around different baseband modems.
In saying that P62 seems to be the preferred for stability & battery currently.

Thanks for your reply. For the case nothing else will do it, I'll try to change to ROM. I'm currently waiting to get my bootloader unlock verified to switch over to another rom.

You can use SP flash tools without unlocking bootloader.

I tried a factory reset without success, but I somehow managed it by setting world mode to 16 (whatever it did, it worked).
Edit: after some research, I found out that I'm running on a global rom with a CN-code, which basically means it is a modified version (fake rom). Only difference I found is a swiftkey keyboard. full code is Global 8.0.5.0.0 MBFCNDG. Just for the case anyone might have it too: get rid of it!
At least the device itself is original.
Gonna try to unlock the phone and get an original firmware on my own when I'm home.

Yep definite vendor/reseller modded rom which are usually added bloat or at worst malware/suspect apps. Best flashing an official rom via SP flash tool asap.

Hi there... how did you fix the world mode. I'm having the same issue, but I tried to set the World Mode to 12 or 16, and it shows me a notification that says "Waiting rf reboot". How much time do I have to wait? What else did you do?
Thanks in advance.
