does anyone know where to find the hidden codes, they don't seem to work on 6.0 marshmallow.
on 5.1 i was able to enter 277634#*# in dialer and go to field test > modem settings > lte band selection to manually select the LTE band i need (phone isn't connecting sometimes, only H+), but now these codes don't work.
have googled a bit, but can't find anything - don't even know if i'm googling the correct terms. is it just called hidden service menu/hidden service codes, or is there a proper term for them?
some codes do work, like imei, but not some of the more technical.
can anyone shed any light on this, i really need to get back to that menu 277634#*# to switch to LTE band 3
haven't tried it yet (downgraded to LL from MM), but apparently *#546368#*815# works in MM. if you have a 818 try that in place of the 815 part

Also 5457#*500 works on my Korean variant with Marshmallow. 500 is my model number so you'll have to try your own in place
How can I access Engineer/Service mode on my OP3? I would like to view LTE information and select a specific band. It was really easy on my old Samsung. I have tried *#*#83781#*#* and *#*#2637643#*#* -When I type these codes, it diminishes itself and nothing happens. Then I tried the old *#*#4636#*#* but it didn't had that setting to select LTE band. I also tried *#36446337# and *#808# and these also don't have that setting.
Thanks
I join the request
*#801# engineer mode
you can try replacing the x with 1-9 *#80x#
At the moment you can't unlock new lte bands, we need a specific patch for op3 (64bit patch) because NVRAM values will reset after reboot the phone.
I've already tried but my pc don't recognizes op3, so good luck, maybe with a custom kernel will work?
For more information on unlocking bands, join the thread http://forum.xda-developers.com/oneplus-3/help/unlocking-lte-bands-t3425871

I've tried with all the sequences from 1 to 9 without success. BTW, I read somewhere the Engineer/Service Mode has a setting in the A3000 to switch from Asian configuration to USA configuration. Is it true?. That will fix my LTE issues.

*#*#4636#*#*
how to enable engineering mode? I tried *#*#4636#*#* but nothing happened!
any solution?
Ps. I'm non-root
For me it's working so I guess you have a carrier version that maybe have this option not available. I have the Google version.
you can always borrow someones sprint sim fir a bit then ull have access to a lot of commands.. i was able to get data programming, debug menu, the 4636 etc etc on a vzw variant just by utting in a dif sim

Work well with Korean model.
I notice that there is an option for VoWiFi in the SVC Menu. Do we need to enable it to use with the cellular network that supports it?

I'm wondering the same thing. I am on T-Mobile which supports Wi-Fi calling but even when I turn this on in the SVC menu, I'm not sure how I can know if Wi-Fi calling works.
Add it 5457#*500#
The only code is usable for my Sprint unlocked V50 is the first one of the OP,but in the options it gives me,i dont have the SVC menu option like i have in other LG models.
I want to see the condition of my battery and its charging cycles.
Any idea or another code?
I tried also the other codes given in the OP.
Sprint V50, use at your own risk, some settings changes requires unlock code, get it from Sprint.

What is the code you used to find the svc menu?
I am trying the 5689#*450# for my Sprint unlocked V50,but it opens a hidden menu only for device tests.

On the V50S (V510N) U+ Korean model I get the hidden menu with *#546368#*510#
While I get the Service menu with 5457#*510#
These are the menu items on V510N
In my LM-V450PM Sprint model the hidden menu is this as shown in my screenshot below.
This is the V510N Service menu

Hi ! I tried to use ##3282# code, but for editing settings I need security code. I have Sprint unlocked LMV450PM smartphone. Does anyone know how to get this security code ?
