Anyone know of any "secret codes" to get into the cell modem / phone part of this device? (like the */# codes for phones)
I see via google that some tablets use codes intered into the calculator.
The main thing I am looking for it a way to disable HSPA+
the "4g" if you can call it that seems to be messing with my vpn. I would be happy to go back to 3g speeds till they get it fixed.
I hope this is the correct forum, if not I apologize. I have a Samsung Showcase from a small area provider. I have been playing around with it and had one question. It seems any directions I find to get into Service Mode (so you can program the phone) do not work. I followed the following:
To access the hidden menus from the dialer:
• Open the dialer and enter *#83786633 then press the Home key
• Open the dialer again (clear previously entry if it is still present) enter *#22745927
• Enter the SPC 000000 then enable Hidden Menu
After this you in theory can dial **772 to access the programming menu, however **772 does nothing when dialed. The phone is pretty much stock right now save for it is rooted. Anyone have any ideas how else you can access programming menus or what I might be doing wrong? I tried to disable the hidden menu -> reboot -> enable hidden menu -> reboot and that didn't seem to have any affect either. Thanks much for any help you can provide.
Well I guess I should have searched for Samsung Showcase for this, I believe I found the options I am looking for. If anyone else runs into this the following worked for me.
MIN Programming
Bring up the Dialer
Dial ##626#
Data Programming
Bring up the Dialer
Dial ##3282#
I did this on a pretty much stock phone (save for being rooted). I can't say whether this would work in a custom ROM or not. The information was pulled from the following post on cdmahosting.com so thanks to DYNET:

So a little background on why I'm posting this. I have owned a G4 G5 G6 and V20, all on Sprint, and none of these devices can ever access the Phone Info section or "Radio Info" section as it's referred to on the Hidden Settings shortcutter App. I believe Sprint or LG removes access to this area on all LG devices. On all of the ones I've owned I can try and access the section but only catch a brief glimpse of it when I try to access using a shortcut app. It is always immediately covered by the same message every time which is: Note This application does not work on this device.
Now I just activated a V30+ a couple weeks ago which I received through Sprint's normal telesales channel and on this device I can get to and modify most fields in the section. I haven't seen other people posting about this so maybe it's standard for everyone with the LS998 Sprint variant and no one really cares or just doesn't have anything to say about it. If thats the case, my apologies for wasting everyones time with an unnecessary post .
If my access to this area is a one off situation and could help lead any developers or more avid tinkerers to any discoveries I'd be happy to test out some things together with anyone with more experience than myself. I've been holding off on attempting to unlock the bootloader and haven't done any PRL updates or resets just in case this access is worthwhile as I've been worried something is going to update and take away my ability to get into the section.
I've included some screenshots. I've cropped them to try and remove some of the more personal data but I think all the relevant sections are covered.
*** Below are some questions and thoughts I've had. I hiding the section it to keep things less cluttered for those that are just reading up but dont have any experience or opinion on the settings/functionality etc***
If everyone can already get to this section, have you changed your bands or modified any of the settings and what results did you see?? I've been tempted to switch up some settings and run some tests but I'm being kinda chicken about changing anything because I can't find any info on people using this menu to do anything except screw up their coverage. A few example seems to be people on different earlier LG models that select USA but live outside the US and then cant get it back to their countries settings.
Here is a list of things I would like to examine more, or try out in these menus. Maybe some of you have already done such or have the same questions. Any feedback would be cool on any of these things or even warnings or endorsements. I would love to learn a bit more about this area and its possibilities.
Under the "Set Preffered Network Type" option I would like to change the current setting of LTE/CDMA/UMTS auto (PRL) to one of the other options and see what happens. I believe this area is relatively safe and can be switched back to the original setting easily. I'd like to switch to Global Auto Mode, Unknown Mode, GSM Auto mode and LTE Only Mode and run some speed tests and see what towers its connecting to in each.
There are four toggle switches, one of which is grayed out. This is the Video Calling Provisioned Switch. Curious if this would possibly become accessible in another mode, or if there was something i could change in a database editor that would allow me to switch this to "on".
The only setting I did change was the one DNS Check. It was originally set to disallowed and I switched it to allowed. I dont really know what changes or abilities this added or took away and have not seen any difference since doing so.
The SMSC when Refreshed will give me an 11 digit number in "" followed by a 3 digit number. It begins with +1 giving it the appearance of a phone number. I believe this has to do with SMS provisioning but am unsure and have not modified the info here.
One part I am very curious about is a grayed out button labeled OEM-specific info/Settings. I have searched like crazy just to try and find some info on whats behind that button and got nada.
In the additional menu section (the three dots) I have an option to Select Radio Band. When Pressed it takes me to a menu which sats "set GSM/UMTS band". This is the area I have found little about other than what I mentioned earlier about people getting locked out of their country settings. I have not touched this setting.
The IMS service Status of my device seems to not populate correctly as I'm listed as not registered or unavailable for all sections as seen in the picture attached. I could swear that a week ago I was showing "registered" but if so thats no longer the case.
Thanks in advance for any feedback.

Do you mean the ones within thd expanded part of the phone info section? If so, I've checked those out and they are blank. Screenshots attached.
So enough people have seen this post now that someone with a V30+ should be able to confirm whether or not others can get to these settings.
Anyone?
There is several other threads about this already. I found them while trying to find a way to get more ?? bands working on my India based phone. Nothing new i don't think and none of it actually helped, for me at least. There is a dialer code for it but i can't remember it.

I'd like to hear what you tried out and see what changed and what stuck and what didn't. . Maybe we can get your phone working better here in the states if we team up on the problem... I know my avatar shows I'm a junior member but that's because I don't really post often, but I do plenty of reading and tinkering myself and I have been in the Telecom business for about 15 years. I'm not an expert or making any guarantees but I certainly don't mind helping out a fellow member here if I can.
Do you have your MSL code? I have mine so if you have yours maybe we can take a look at how my phone is provisioned in the ##data# menu and get your bands setup the same way since mine should already be configured to the proper bands for the U.S. Between modifying that area and making some changes in the Radio info section that could do the trick for you. Let me know if you'd like to work on it and we could PM or you could reply with a run down of what you've tried and how you're setup now and we could go from there.
Cheers.
*#546368#*930#
Field test. LTE band selection. Selecting any band from the menu just makes it completely lose cell signal. After selecting a band it just either says success or fail.

Ok so that dialer code doesn't trigger anythibg on my model. I also tried replacing 930 with 998 and tried replacing the *# and #* with just ## and no luck. But no worries.
I'm thinking you may need to change your settings in two menus in order for the new settings to work together. If you go into your Data menu (##data# or maybe *#data#* on your model) and update the information there to match the ones I am attaching in my screenshots and then go into the Radio Info menu and select a similar setup to how my device is provisioned you may see some success.
Thoughts?
You would need your MSL code in order to change the settings in the ##data settings....
Where do i get msl code?
Neither of the data dialer codes are working for me.
Oh those settings are only for cdma phone?

There are a bunch of tips and tricks to find your MSL code posted throughout the boards, but I have only ever got mine from the carrier. If you call customer service you can usually talk them into giving it to you, though their policy on this is to not give it out unless your phone is fully paid for / out of contract. If you tell them you are working with a tech in a store and need it for provisioning they will normally give it to you.

I know this may not be in the right place but does anyone know how to bypass frp lock on this phone
Hello together,
at first, sry. for my bad english
I have buy me a Redmi Note 5 in the "Global Version" with 3/32GB.
The Phone is great an not to small.
Only the options "VoLTE" and "Wifi Calling" i miss.
Bevor i had a Huawei P10 and with this phone the VoLTE and Wifi Calling was activated and the function are great (german Vodafone).
Now i search it on the Redmi Note 5 Phone. But i didn´t find it.
When i go in to the Mode *#*#4636#*#* i can see in the Phoneinformation 1 (i have only 1 Sim Card installed and 1 Micro SD Card) that the "VoLTE" and "WLAN-ANRUFE" (Wifi Calling) is Off.
I can´t activated with the Button.
Can you help me? It´s very important for me.
Thanks a lot....
Greetings from germany
PS:
Android Version 8.1.0 OPM1.171019.011
MIUI Version MIUI Global 9.5 Stable 9.5.13.0(OEIMIFA)
Edit 1:
I have found a solution.
When you have the same problem with VoLTE , go in the APN Settings from Vodafone and go to edit the "APN-Typ".
it look original: default,supl
after edit: default,supl,ims
after, go in the dial app and call the number:
*#*#86583#*#*
after input this dial, a small pop up is screening "volte carrier check was disabled".
After restart you have (i have) the VoLTE Screening at the top and i can now activated and disactivated in the menu.
The same in the dial code *#*#4636#*#*.
Now there is VoLTE ON
Ooo... a many reaction

Hi, thanks for the VoLTE solution. Works perfectly. I am also using the german Vodafone Network.
Did you also find out something about the Wi-Fi Calling? I only found some Custom ROM Solutions and that it was possible somehow in the past.
But I would prefer to stay on the stable global ROM.
Thanks. :good:
If i should find something I will post it here as well.

I rechecked the link and found out that the mentioned module seems not to work.

Sorry, I did not check it deeper the first time, because it was no option for me.
Thank you
I tried it on my Redmi5 EE network UK and it worked.
Thank you ??
yes of course
Any news on WFC? Does it work on any ROM?
I saw on youtube WiFi calling is available on redmi note 5 pro. Is it possible to flash pro firmware on non pro redmi note 5 in order to activate it? Has anybody tried that?

wow that does indeed seem to activate the VoWifi setting on my Note 5! - it removes the carrier check, so it seems to force the setting to be available in the menu, like the VoLTE carrier check disable.
thanks
if you want to check if the vowifi work you must set airplane mode and after that only wifi on, and then try to make a call over wifi...
in my case (redmi note 5 pro) i can't call over wifi and i have try many solutions
please if someone know a fix tell us...
(base on GSMARENA)
This phone support the following 5G bands:
5G bands 1, 3, 28, 41, 77, 78 SA/NSA
however, my current phone sim need to utilize the Band 40, n257/n258 for 5G,
anyone know how to enable or activate these bands? Is there any MTK engineering software for this purpose?

I'd like to help but I'm not sure if the solution I would use would fit your needs and capabilities.
The (apparently secretly hidden) Android Activity it calls is apparently
com.samsung.android.app.telephonyui.hiddennetworksetting.MainActivityBased on what a free google free ad free gsf free shortcut inspector says
Activity Inspector
Having said that, I can bring up the HIDDEN Activity that allows you to select the bands available on the phone by calling the activity directly.
C:\> adb shell am start -n com.samsung.android.app.telephonyui.hiddennetworksetting.MainActivity
They even make apps that do that for you such as this one.
Network Mode Universal
See my screenshots below for my phone.
Hope this helps.

Thank you very much for your suggestion. I have tried all these and found:
Network mode universal - this is similar to *#*#4636#*#* for phone information.
Shortcut Widgets (+ Inspector), nothing shown in POCO X3Gt for band. it "maybe" work on your Samsung phone. Could not find any band information.
However, when get into *#*#3646633#*#* Developer option, it shows bands as attached photos, the Band 40 is greyed, no possible to enable it.

My response will be in two posts because I don't want to confuse you with the response about "Shortcut Widgets" so I'll take that separately as it's really useful only as a final step.
As for the band B40 being grayed, out, that is a problem.
My only experience with this band selection is on my phone, where nothing that is listed is grayed out. That is, for example, I don't have Band B28 on the phone (AFAIK) but that band is not listed either.
What I have that is listed, as far as I know, can each be checked.
So the fact you can't check a band that is listed, is really, I think, the problem all of the users here have to put our heads together to figure out why that is the case.
I don't know why you can't select Band B40 even though it's listed.
I can only suggest tests you can run to perhaps figure out why.
a. Anyone else with the same phone could run that test for you.
(Let's hope someone with that same phone will see this request.)
b. Maybe you can try one or two other "band selection" apps?
(This would eliminate it being a bug in that specific program.)
c. But the real problem may simply be the phone hardware doesn't support that band.
(I don't know any way around that.)

Ah. I think I figured out what I'm doing differently from you since *#*#4636#*#* doesn't work on my T-Mobile Samsung (we really need someone to test this using the same phone you have!).
My Samsung has its own app from that same outfit I referred you to
Network Mode Samsung
I'm guessing that your "network mode universal" is (maybe) giving you a list of all possible bands but (maybe) not just the bands on your phone alone like my "network mode samsung" is apparently doing for me.
If you can find a network mode app for your specific phone, that may show just the bands you need... but... you already ran the *#*#4636#*#* dial-code to bring up the hidden activity I think... so you may already have seen that the dial-code you gave probably brought up only the bands which are available to you.
Hope this helps. I'm NOT an expert in this. I would hope others with the SAME phone as you have can confirm our suspicions or prove them wrong (better yet).

At this point you don't need Shortcut Widgets + Inspector, as it's only useful to find out what the hidden activity name is, and even then, you only need to know the name if you're going to create your own shortcut to bring it up.
It's useful mainly for HIDDEN activities, because once you know the name of a hidden activity, you can bring it up in a single click if you know what you're doing (you have to create a shortcut to it).
As far as I know, it's the ONLY APP in all of Android that does what it does (although others may exist) so it's a keeper, for sure; but it only tells you what you want to know AFTER you've already brought up the "activity".
An "activity", if you aren't aware of what that is, is kind of sort of like a "pseudo public page" inside any Android app, which can be brought up if you know the unique name of that activity.
There are something like three or four hundred public activities in the Android "Settings" app alone, while most apps have a few dozen or so public activities you can call up directly, which means there are about a thousand or so, which is why you might need an app that tells you what activities are brought up when you do stuff on the phone.
However, if you can ALREADY easily bring up the band-selection activity on your own, you won't need this app to tell you that so I'd ignore it for now. Sorry if I wasted your time.
Appreciate very much for your reply with detail explaination.
I believe this Dimensity 1100 is prebuilt with all bands when sold to each different phone company, however, MTK will price differently base on the the number of bands given (enabled), some companies may sell its phone with lesser bands so to lower its price to make it more competitive.
This problem is hardware problem, so it could only be done with MTK special engineering software or some special code to enable/disable them.
This is just my suspicion, I may be wrong....

I agree.
I hope you find someone with the same phone who can try it to help. Or someone who knows the MTK software. Good luck!
