Hi there
Can anyone tell me the "secret" code for Network selection ( RF band selection ) for the GT-I9295
I´m have rooted the phone and now i need the code to enter the Network menu to activate the locked 4G band.
The *#2263# code does work for S4 ... but not for S4 Active !?!
I have tryed 4G toggle apps, but they only work for S4 ... but not S4 Active

Hi All,
As i am new to XDA and AT&T Samsung Galaxy Tab8.9 SGH-i957 too. i need help.
I had a AT&T Samsung Galaxy Tab8.9 SGH-i957
Android Version: 3.2 Honey Comb
Base Band : i957uckj7
The country i have only 2G network supported NO 3G or 4G.... i am confused that how my device can make a call as there is no dialer option in device menu. but my device shows my network signals in the bottom right corner of the device and i am able to use GPRS / EDGE and can make SMS / MMS from my device. But "NO CALLS"... Please help how can i make call from my device as AT&T is not supported in our country and i had inserted other network SIM card with data plan.. from where i m using SMS / MMS , GPRS / EDGE service.
Secondly my device is on Honeycomb i want to update it on ICS but when i download Kies on my PC and attach my device it indicate that device is not supported with Kies.... Please help how to update without rooting my device.
i am thankful if someone help me on both issues....

those functions are disabled. what are you trying to do ? there is a secret service menu on the phone from olleh which might be of some help.
319712358 and pasword id 774632. you can select only lte in the network mode etc

Hi there
As above I entered a service menu on my Samsung Galaxy S6 *#9090# it brings up DIAG menu I believe - I may have changed one thing I'm unsure?
Is the default for RAMDUMP Off? I have it as off atm but unsure if it was off or on when I first went in there.
I was trying to have my phone lock on LTE Band 28 700Mhz which is one of the spectrums Optus in Australia use and it gives me the best signal strength at home and at work
Thanks in advance
Hello,
So i have a Galaxy S6 (Cricket US) Unlocked and i am using it here in Pakistan.
Problem is that everytime i try to enter Ussd code it gives me this error " Connection problem or invalid MMI code." and this pops up instantly i can't even see the "Ussd code running" that loads initially when you dail code.
I can still make calls and send texts even the imei check code (*#06#) is working.
This is not my carrier problem as the codes are working on other phones.
I have searched everywhere (google,yotube etc) and tried every solution but nothing helped me.
So far i have tried :
1-Restarting
2-Using , and + trick
3-Booting in Safe mode
4-Factory Reset
5-Selecting Mobile Network many times.
Here is some info by Samsung Phone info app
Model: SM-G920AZ
Knox Warranty: 0x0
Firmware CSC Code: AIO
CSC Country: USA / US
Mobile Operator: Zong / 41004
Android 7.0 / SDK 24
There might be a lock or some of its LTE(4G) bands, or the network type is set to LTE(4G) only (though this shouldn't have survived the factory reset), try setting the network type to auto or 3g/2g. Enable CS+PS (VC) in the menu with the band selection if it was changed there previously.
