Hidden service codes menu for 6.0 marshmallow

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

Need my MSL

So I got an LG G5 from a friend who worked for Otterbox, he had a bunch of credit built up there so when he quit he got some phones and gave one to me. I was able to get it unlocked without TOO much hassle but didn't realize I needed an MSL code to change the APN to work with my network. I've called sprint a bunch but they don't wanna help unless I have a Sprint phone number. What can I do? I really don't wanna have to use this great phone without Data or MMS...

Probably need to go into a sprint service cebter and ask politely for the msl
Sent from my LGLS992 using XDA Premium HD app

Here is a guide from the old LG G2 days however I am fairly certain this was what I used when I got mine. You need the Basic Flasher method the dial code won't work. Oh and use the current LG drivers instead. Check here. It's pretty simple to figure out. And by unlocked I am guessing you mean sim unlocked eh?

the guide geeksmurf linked is how i got mine.

Hit me up on kik CB6767 I can give you your msl, I have access to all that info

Hi, i send u a Kik msg, thanks!

I have an MSL code but now way to add an APN from APN menu

If you know someone who has a sprint account, have them activate your phone online and then just swap back to their phone.
They will get an email with the MSL code for "manual activation" - kinda handy.

ya i was gunna say if u have an extra sprint phone just log into mysprint account. activate the extra phone then u can activate the g5 back and when it comes to t he congratulations screen it will tell u the activation code and say u may need this. that is the msl. keep in mind u have to give it some time to swap back and forth because the sprint database has to update and all. usually if u try and do it right away u get an error because the original phone is still showing up on the screen.
u shouldn't need the msl code to add apn though. i unlocked my sprint g5 and added the att apn through the normal settings menu and it saved it just fine. u have to look at the other data settings though and allow gsm i think.

[Help] how to enable engineering mode?

how to enable engineering mode? I tried *#*#4636#*#* but nothing happened!

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

service mode

Hi,
I cannot access to service mode menu *#2263# , blank screen, I have exynos versio of note 10.
Any idea?

Works fine on my US SD model.

My unlocked 10+ flashed with t-mobile firmware works for that service mode.

BTW did you try other codes like *#0*#, to see if they work? I also remember something about Exynos having different sequence for some codes than SD in the past, but I don't remember details. I think there are some apps that can list all the codes available for your phone, so that would be my next step.

dl phoneinfo.apk or similar that lists all the dialer codes for u to try..
if none work then its possible ur carrier disabled them.. if u have root u can enable them.. on sd devices you would enable in the file /efs/FactoryApp/keystr and /efs/carrier/HiddenMenu..
i have vzw who blocks dialer codes so i always have to enable them manually..

But we can't enable on vzw on note 10 cause no root correct or did I misinterpret?

ims code for n9750?

Mine does the same thing, but only because I am trying to activate the IMS service via the shortcut. IMS settings do not seem to do anything.
Try posting what it is your trying to do or accomplish.

If I knew the code I would have just posted it.
I asked what you were trying to accomplish because I am trying to help by looking to see if I can find the code.
So far without knowing what your trying to accomplish this is the most likely answer. A question on the same subject matter your asking was discussed previously (linked below). A reply was given saying that the reason why your getting the code prompt is because your shortcut is opening/calling the IMS service (and not the IMS settings).
Other comments across the net indicate that direct access to IMS settings (not the IMS Service) is/was blocked post oreo firmware. I doubt this (direct access to IMS settings) is gonna be easy to do without root.. Provided it's even accessible via root
