Service Menu/Engineer Mode? - Verizon Samsung Galaxy S7 Edge Questions & Answers

Hello to the community!
I need assistance getting the Service Menu to work.
I followed the S6 instructions:
Goto /efs/carrier/hiddenmenu
Change to ON
Save and reboot
Dial *#0011#
Now a menu does come up, but it's blank (see attached pic). Am I missing something? Please help!
P.S. I've tried Phone Info app, doesn't help a bit

No one ever answered this so I will. I am 99% sure the Verizon version has to be rooted to access the diagnostic menu functions. It can still perform some of the single test dial codes, but I couldn't tell you there.

I am rooted and was at the time of posting. Doesn't really matter for me now, have an S8+.

This is the code for the service menu for Verizon phones
*#27663368378#

not on galaxy J737V it dont

Not all verizon phone come with Enginnering mode on them, I have worked for Sprint as Engineer contract for AT&T, Verizon, T-Mobile. Verizon is in class of it own, i just pruchased two SM-G30V one came with Engineering mode on it the other no engineering mode. Verizon's Engineer or Cell Technicians actually have software to push to the phone Via USB cable. Rooting a Sprint, Tmobile, AT&T all for it makes test easy with out cables, But verizon is not worth rooting and usually has side effects that i had and had to use the verizon Software to repair. Hope this helps.

That is your opinion (which you are entitled to) and your experience. I have S7edge, Verizon, been rooted for about 2 years now with ZERO issues. I also have access to this Engineering (Service) Mode- not that I have any use for it.
If you had to use Verizon's "software repair tool" then you had a separate issue.
YMMV

Unlocking Sprint Samsung Galaxy S 4G

Alright, I've checked everywhere, so now I'm asking you guys. I have a SPRINT Samsung Galaxy S 4G phone. I would like to simply switch this thing over to another network (PagePlus), and it would be a shame to simply give up. Yes, I understand it's CDMA, but no CDMA Workshop tool I download seems to understand what it is. I have CDMA WS 3.7, and every time I click "read" it simply locks up, it doesn't matter what mode I'm in; Charging, Mass Storage, Debug on or not. So first, I guess it would be helpful to find a working CDMA tool for this particular model. I've flashed it, it's rooted, I have superuser abilities, and even a terminal emulator. Superoneclick, HTC Sync, QPST 2.7, you name it, I've tried it. I'm even willing to go so far as opening this thing up if I have to! What do?
I don't use said tool, but didi you try download mode? From power off, hold "1" and the hold power at the same time. Idk if it will help.

never used it, but if it says cannot talk to phone, did you install the Samsung drivers? You may also need Android SDK too... idunno... check the software.
Just making sure here: You are talking about the Samsung Epic 4G for Sprint, and not the Samsung Galaxy S 4G for T-Mobile, right?
Posted by Mr. Z's Epic 4G.
Wow. Page Plus has horrible phones. They have 5 year old VZW Phones. I see why u want the Epic there. So far, I think you can only flash to Boost Mobile and Cricket. Evo can be on Metro PCS.
Still at it
ungovernable: Yes I have all of the Samsung drivers, sry I didn't mention that before.
Zanderman: Yes, that's why I bothered to type sprint in all capital letters in the original post. Actually, I still have a standing trade offer up in Craigslist, for the same model phone with T-Mobile, just so I could unlock THAT one. So far, no one has bitten.
xboxfanj: You're telling me! Horrible phones. I've seen the T-mobile version unlocked (easy!), and other smart phones from both Samsung and Sprint unlocked too, so I'm trying not to give up. Once I find an answer, I'm gonna post the crap out of it.
Thanx to everyone so far for even bothering to read my tripe of an issue, I still have hope we can do this, and I'll keep finagling this thing.
There are sites that claim they could do it.
Here is one:
http://vannuyswireless.com/ppactivations.htm
I have never tried myself, just passing on the info:
This link may have some relevant info also:
http://www.howardforums.com/showthr...S-Sprint-Epic-4G-onto-Verizon-to-use-PagePlus
"We Can Activate Most Any Verizon Phones As Well As Sprint Boost MetroPCS On The PagePlus Network-The Cost For A Simple Activation Is $5-You Get Activation On PagePlus W A New Number in (818) (310 ) (323) Etc.+$2.00 AirTime.-Port-in Activations Are $10 (Port-in Is When You Transfer Your Existing Telephone Number To PagePlus) Non-Verizon Phones Will Need To Be Brought In To Be Flashed Manually And Work Times Vary By Model."
Look at the thread about switching to cricket here in the general section and follow all the steps up until you put in the cricket prl, instead put in the one for your carrier. Unfortunatly, I don't think you'll be able to get mms and web though, i don't know those settings for your carrier....

#1. Pageplus needs to add the Phone's ESN to their network, otherwise all that you're doing is in vain.
#2. You need a full Licensed version of CDMA, so 'assuming' you paid 100$ for that copy of CDMA WS 3.7, it is faulty. Even the cracked versions of CDMA aren't cracked at 3.7, it's like 2.6 or around there.
#3 If you downloaded the Trial version of 3.7, that's why it won't work, there's a high chance its on a different com port.. though this I can't vouch for, seeing to that Odin for me uses one of the first com ports on my laptop.
#4. Try CDMA WS on a different laptop.
P.S. : Having faith you get it to work, you'll want to change your MSL code to: 000000

You need to dial ##8778# and set the USB mode to "Modem" before CDMA Workshop or any diagnostic software transmitting over a COM port will be able to talk to your phone.

The Samsung Epic 4G Flashing Guide (for alternative carriers)

The following is a guide I put together over the course of today about flashing the Samsung Epic 4G to both Cricket and Page Plus. This will work with phones that have bad ESN's (at least, Page Plus and Cricket) -- and with phones that are totally fine and saintly, but maybe you want to go to another carrier for a cheaper rate?
https://docs.google.com/document/d/1E4nNITQnzEoEkkVp4j7k_N_yghvNh_SozuKe3az_Nx4/edit?hl=en_US
In the future, as more information becomes available, I'd like to incorporate other carriers that people are flashing (Metro PCS, Boost), as I find out more. The idea is to build a one-source guide for everything you need from start to finish.
The guide takes you from the very beginning to the very end. PRL's, etc, are all inclusive. I've flashed my Epic to both Cricket and Page Plus successfully -- just like Page Plus's coverage/quality better (and cheaper... but hardly any data -- user Wifi). Even if you don't want to flash, it still has useful things like unlocking your phone for use on any carrier that will take it.
Any comments/suggestions are greatly appreciated.
Just as a note, I'm no longer involved in the Epic community. I migrated on to a newer device. http://forum.xda-developers.com/showpost.php?p=34802383&postcount=72 If you need any help, I will still be available through PM's to the best of my ability.
The HA/AAA shared secrets for Page Plus are not "vzw", trust me. I'm running with full 3G on Page Plus right now and after many late nights I realized the only way to get it was a temporary clone to a Verizon phone so that I could get the proper keys through OTA programming. Unfortunately posting a guide to that would probably get XDA on my/your ass. With the "vzw" password you will technically get 3G but it will be throttled to 1xRTT speed (about .1 Mbps). I don't know if the same is true for cricket or not...
Nevertheless I'm sure someone out there will very much appreciate the time and effort you put into this; props!
So using this guide i can unlock the epic meaning ill still be on sprint, but if i suddenly wanted metro i can just take it to the store and have em flash it?
Sent from my SPH-D700 using XDA Premium App
I request a stickey
I haven't flashed to Metro, but if I can find someone that supports all the features I want, I may give it a shot and write a guide. Does Metro support bad ESN's? (Long story short, got scammed by a Samsung Epic on CraigsList, Sprint said ESN was clear, but is still linked to scammer's account, who refuses to remove, etc, and commit insurance fraud... Talked to insurance and he's in jail now, apparently, but phone will probably be forever blacklisted on Sprint).
Currently, I'm trying to find a provider who can give Google Voice support and Data... MMS I'm not so concerned about. Page Plus is my only "good" option now (a step above cricket, but limited data). Any thoughts? Metro PCS apparently doesn't support Houston, TX when I try to find a plan, either.
EDIT: I may try to give Cricket another go. I've been reading a little bit more and have learned a bit about making Cricket work. Would be nice to try the $45 plan on Cricket to save some $$$. I've talked with some people who claim MMS and Google Voice CAN happen, but it's a little more tricky. Will let you know as I figure it out (must wait a month to not lose $30 from PagePlus).
im confused i dont have these MDN and MIN and your guide says i should have gotten them when i got the phone? is this from sprint and am i supposed to call?
also i got the phone replaced by another epic today. the phone kept trying to auto activate. it still is trying to autoactivate. i swapped the epic out for a nexus the other day. what should i do. if you can pm me and talk over the phone that would be great. my mom is going to new york wednesday and i want to pageplus this phone before she leaves.
I've gotten a couple PMs regarding the HA/AAA keys so I'm going to say this. I would gladly provide them for you guys but that's just not how it works. The keys change every time I (re)activate. They are probably tied to the time and the MEID of the phone, possibly more than that. My keys wouldn't do any of you any good.
It sucks, but the only way that I know to get them is to use a Verizon phone.
duh ask from carrier. now i followed all the steps including the manual update because auto won't happen. afterwards i autoupdated but it aint working? or am i supposed to buy airtime now?
not getting any help. please someone
i completed all the instructions and i can't dial out. i have a triangle at the top. when i call pageplus they are asking for a esn. what the heck am i supposed to do
What happens when you try to dial out? Have you bought/activated your service yet?
yesh i just activated a service using crap motorola. the prl on the page gave me a triangle on the bar i switched it to an older modified one for sprint. when i dial out i get the message welcome to verizon wireless your mobile number is not active or ....

i switched back to the prl on his thread. i wonder if he switched the prls from cricket to pageplus on accident? this sucks i been working all day got school soon and no help for my mom. ahh
So, the PRL isn't working for you, eh? The PRL for Page Plus is 51--- something -- Cricket is 42700.
Are you sure that your phone is unlocked? Are you sure you're reading from phone to get current settings before writing PRL, phone number, etc, back to the phone? (it should prompt you for your MSL -- which should now be 000000) Then make sure you fill out the data correctly. You should be able to get your MIN/MDN by asking for them from Page Plus. I openly told the rep on the phone I was trying to flash the phone myself and he gave me all of the information (and then a little bit more -- unfortunately, not the HA/AAA secret). I was actually originally using my Motorola Droid and asked them to try putting ONE OTHER phone on, to test it out (my Epic). Long story short, it did.
Page Plus uses Verizon's towers -- so it's OK if you're getting that. My phone apparently "roams" as well, but I have yet to have any issues. It's just what shows up.
I've heard that Cricket (prior carrier) can be configured to work 100% with the Samsung Epic for the $45 plan. When my month of minutes runs out, I'll try swapping back and seeing what all I can do... I learned a lot while working on this, so I think I have a little more expertise on this. Prior, I had never unlocked my device, so auto-activation never worked with Cricket! Eeek!
Anyway I will of course write something up about that.

cool. i will stick to sero truly duly unlim 4g wimax. anyways. roaming is normal? where did you get the prl? i am using an older prl i found online. i was getting the message you might be charged for roaming prior to each call.
I do not get that message for my PRL. If I remember correctly, PRL's are just how your phone knows which tower to connect to. I've heard they vary based on where you live. In any case, since PP offers nationwide coverage, I'm not thinking I'm roaming and no charges have shown on my phone yet.

yeah that's what i am guessing. i flashed different prl's and i still get the same message. can you please check to see if the prl wasn't switched or renamed incorrectly or better yet can you give me the source? prl's get updated and i have an older one. too bad my parents already left for new york i hope everything works out well for them

Newbie question. I have an unactivated sprint epic. I can't seem to get QPST to recognize the phone. The phone shows up as a modem in the device manager but QPST appears to see something connected but doesn't see the phone as modem. I've rebooted and switched USB ports as well. Any ideas on what could be wrong?

Do you have the drivers for the Samsung Epic 4G installed for sure? What OS? May want to potentially try running as an Administrator, just in case (I don't have this issue, but I know some folks at MS have told me their hardware-heavy programs don't work when they aren't in Admin mode).
Make sure to uncheck the box in QPST about diagnostic/etc ports. Just enable all the ports you can in QPST Configuration and you should hopefully see it.
Are you absolutely sure it shows up as a Samsung Modem?

I am using XP. Under Device Manager -> Modems, it reads "Samsung Mobile Modem #2". I also installed the drivers from the Samsung support site. For ports, QPST reads "COM5-USB/QC Data Modem" in the "Add New Port" window with the box unchecked. In the "Ports" window it reads "No Phone" under the "Phone" column.

[Q] Verizon S5 Wont enable LTE - Ideas?

Bought a barely used S5 off ebay which supposedly was working fine. Everything else seems fine except it only connects in 3G and never LTE, and I live in NYC so it's not a coverage issue. Have gone through the network settings, restore, reset, took to Verizon store and they swapped in 2 different LTE SIMS. Nothing seems to make it want to do LTE. Is there a diagnostic tool or mode for a Verizon model? Seems they have locked out the internal diagnostic screens for the Verizon phones so none of the #* menus come up. Would like to try to get this one fixed rather than return it to the seller as it is a very clean and unblemished phone, but not sure where to start. Verizon store had no idea and since it was bought 2nd hand they couldn't do anything for me. Any ideas where to begin or how to access either a software tool or internal tool to test the radio?

Regarding diagnostic screen, you can use Phone INFO ★Samsung★ app or Shortcut Master app, open Menu > 'Secret Codes' and scroll down to these secret codes to launch:
- 27663368378: Service Main Menu
- 197328640: Debug Screen
- 2263: Band Selection
Note: ROOT is required to launch the secret codes. It is due to Samsung security policy.

VZW Activation

I bought VS995 phone slightly used. Upon getting the phone I used the Dirty Santa Root and Bootloader unlock method. I finally got around today to going to VZW and getting a new SIM and activating it on my current line. Activation kept failing. It was at the point where everything entered fine on their end , but on the phone it took about 5 minutes before giving the activation unsuccessful message. Has anyone encountered this issue? Rooting and unlocking the bootloader before activating it with a new SIM card? They were having problems with their activation servers this morning and said that since it's a new SIM it could be getting hung up with their server issue. I'm going to try tonight from my house. But was curious if I need to take any extra steps to get it activated. If my note 3 had a nano SIM card in it, I would have just been able to swap without an issue.

Ultimately your trying to remove the programing from phone.. And or re program it on vzw. Did you try calling *228?
I was finally able to restore my phone to stock via uppercut and LG up. Got it activated on VZW today as well. Tomorrow I will set out to root again amd unlock the bootloader again. Thanks for your help. Have you encountered any Bluetooth issues with the phone? For some reason the phone won't recognize my car. Its a 2016 Honda. The phone will recognize other Bluetooth devices though. Just curious.

LG V20 CDMA to LTE/GSM switch via Hidden Menu

First of all credits go with many thanks to @hyelton for the instructions and original post for LG G5!
NOTE: starting with ZV8 firmware version Sprint has patched its ROM, so this option is not available any more.
Now short instructions on how to switch your LG V20 from CDMA to LTE network and configure your 3d party SIM APN settings:
1. Download attached HiddenMenuCall app and install it on your device.
2. Start the application and scroll down to IOT(CDG2) row and press it.
3. Next scroll to LTE settings and press it.
4. Select afterwards Operation Mode and change it from Production to Lab Network
-------
After that the phone will reboot.
-------
5. After reboot start HiddenMenuCall again and scroll down to IOT(CDG2) row and press it.
6. Next scroll to LTE settings and press it.
7. Now select APN Settings and press it.
8. From the upper right corner press 3 dotted menu and select New APN.
9. Configure your APN (refer to Biggest APN list) and press SAVE again in the 3 dot context menu.
That's all you'll now have a LTE/GSM enabled device

VoLTE will only work with Sprint and only if they support it.

yea dude was selling it as a way to unlock the phone. It works half ass, but I ended up getting sprint to UICC unlock my phone so it was a waste of money for me. my phone is unlocked now, just got to root it so can get it to show like Verizon,or what ever service I end up using. well got to flash the rom of what ever carrier I am going to use

That's terrible. Report sellers that do that.
But You can't do what your wanting to do. You can't put that phone on Verizon, it doesn't work that way. Unlocked means it will work on AT&T, T-Mobile or any other GSM carrier in the USA or outside the USA.
2. I don't think there is root for the sprint model.
3. You can't flash other carrier firmwares. You can ONLY use the firmware that's on the device. If you flash a different carriers firmware you'll brick your device..

If there's root available for your model yes. But if not then no. UICC unlock won't have anything to do with being able to root or not.

I can still root cause has not updated. already asked me2151. it will work on Verizon, had my sim card from Verizon in it and worked just fine except not showing Verizon symbol in the service corner, its a unlocked phone now, I don't think it will work on gsm cause of it being a cdma phone. I mean worst case scenario I will use on boost mobile.

Verizon doesn't officially support non Verizon devices meaning non LTE data may not work or work correctly.
It working on Verizon doesn't mean it's unlocked. Unlocking a phone relates to GSM not CDMA. Also if you use that apk your phone will work perfectly fine on AT&T or T-Mobile. Just like the Sprint G5 does.

I have that app plus my phone is sim unlocked, it was paid for in full so I had them uicc/sim unlock it. that is what I was trying to say idk if I misconstrued that.
OK first problem I want to sort on my V20 is Tethering shutting down after 20 seconds, every single time it's switched on.
I'm in the UK and have the H990ds Taiwan variant.
When trying to change APN settings some options are not there when I compare to the settings on my Z2, and some other options that are there cannot be edited.
So this thread looked hopeful but I've installed the apk from the OP link and this is what I get when I open the app -

This thread of for specifically making a US carrier device be network unlocked. This that most likely won't be of any use to your model.
That's a very strange issue. Settings with your APN won't make your hotspot shut off. You can turn on hotspot even if data is not working.
Seems more like a software issue or hardware issue.

Thanks. But so far after much googling APN settings are what everything has led me to believe is the problem. So I'm trying whatever I can.
Back to the drawing board....

Have you tried performing a factory reset?

Very interesting post. As mentioned, this App is unfortunately intended to be used in the states only. Should it be possible to help us switch the bands for different carriers in different countries, would it be great!
@hyelton
The problem was down to a Sony app that I inadvertently installed when setting up my V20.
Thanks for your help.

First of all credits go with many thanks to @hyelton for the instructions and original post for LG G5!
Now short instructions on how to switch your LG V20 from CDMA to LTE network and configure your 3d party SIM APN settings:
1. Download attached HiddenMenuCall app and install it on your device.
2. Start the application and scroll down to IOT(CDG2) row and press it.
3. Next scroll to LTE settings and press it.
4. Select afterwards Operation Mode and change it from Production to Lab Network

After that the phone will reboot.

5. After reboot start HiddenMenuCall again and scroll down to IOT(CDG2) row and press it.
6. Next scroll to LTE settings and press it.
7. Now select APN Settings and press it.
8. From the upper right corner press 3 dotted menu and select New APN.
9. Configure your APN (refer to Biggest APN list) and press SAVE again in the 3 dot context menu.
That's all you'll now have a LTE/GSM enabled device

I don't see the IOT (CDG2) menu when i open the hidden menu on my H918. Does this apply to T-Mob?
