[Q] hidden codes

so on the Galaxy S I9000 there are a slew of codes that can be used to access the engineering menu for the phone, change the csc file etc. -- change the enabling structure of the phone in effect.
So my question is: how do you (a) access and (b) change those codes for the galaxy Tab 10.1 when it is a version (4g Rogers in Canada) that does not have a phone dialer?
do you install a modem to activate a dialer? or does the sim card control that availability on the Tab 10.1?
anyone played with this yet? is there another way to access the codes not using a phone dialer?
There is an app that Samsung uses called Factory Mode. It brings up a calculator looking interface which allows you to enter numbers and # signs etc. Don't get too excited though. Most of the I9000 codes don't work just giving a Wrong Format error. I don't know if you need this special app or if any calculator app will work.
How do I know? I just got my tab back from Samsung after sending it in for service and it came back with the factory mode app on it.
I wonder what's the purpose of that "Factory Mode" for end users, aside from saving time as lock screen/mechanisms are completely nonexistent.

Privacy lock feature does not work anymore

Hi, I'm using a Gear S with a Galaxy Note Edge in Germany. The network operator is Congstar, a subsidiary of Telekom Deutschland. After updating my Gear S Model SM-R750 to SW Version R750XXU2B0G2 the privacy lock feature for my Samsung Galaxy Note Edge mobile phone does not work anymore. Even after resetting both devices it is not possible to activate the private lock feature with the Gear Manager App again.
Gear S Model SM-R750, SW Version R750XXU2B0G2
Galaxy Note Edge Model SM-N915FY, Android Version 5.0.1
Any ideas or help would be highly appreciated.

S6 edge network mode issue works with gsm only. Any solution please

Dear
I have bought my s6 edge device about a month earlier. I am facing an issue that my device works with gsm mode only. When I try to change the network mode from gsm to WCDMA or LTE network goes out and messages appear not register on network and emergency calls only. I have checked the same SIM with htc and other galaxy devices and its working fine but when I try to do this with my s6 edge it shows the same issue.
Any solution please
Maybe try doing a factory reset?? What model is it again?
Hard reset done but issue is as it was. Model is SM-G925I

Emergency calls only, not registered to network help

So I've been unlocked on Sprint galaxy s8 plus Sm-G955U and switched to MetroPCS. I flashed this root firmware from this forum for root. https://forum.xda-developers.com/ga...root-g955u-g955u1-snapdragon-sampwnd-t3658911 . Did the mps code. My service was working had to reset my network many times but I had service. Now for about three days I get emergency calls only in top left corner . I try to make a call and it says not registered to network. I have signal bars . My number reads. My sim is working in different phone. I checked my imei number it's original. I tried air plane mode , LTE to 3g/2g, checked a website to to see I was blacklisted it was clean. I switched firmwares. My voicemail pops up when I insert my card but I can't call it. Tried MetroPCS US LTE and MetroPCS apn can't connect to t mobile network operators. I'm lost. Is there a repair network for this device? Does anyone know how to get my MetroPCS service working again or why it's saying emergency calls only and I can't register to a network? Please help. I checked blacklist because I bought this phone someone and thought maybe that was the problem. https://imei24.com/blacklist_check/

Can anyone help me please?
If reflashing the firmware didn't help, you may need to search for someone to use a box to repair your network. A quick Google search showed me that there are options available. Just search "repair network SM-G955U"
Good luck!
