Hello, I need some help. I have the d802 model of the LG G2 and I have a problem: in order to use 4G I have always to go on the phone app and type the code *#*#4636#*#* then a menu opens and I have to go Phone information and then Set preferred network type and finally select LTE/WCDMA/GSM. But he problem is that this setting always reset when I restart the phone or even randomly (It always go back to WCDMA preferred), so I can't use 4G anymore.
Ps: Even while LTE/WCDMA/GSM is selected I'm not able to select 4G at Settings > Tethering & networks > Mobile networks > Network mode, but it still works
Ps 2: I'm using pure stock 4.4.2 KitKat ROM
Ps 3: I did hard reset the device
Ps 4: My mobile service is Claro, from Brazil
Anyone please?
Please I need help with my S975L Samsung Galaxy S4. I tried everything to sim unlock it but nothing worked.
I read that one method was entering to the serviceMode Menu (*#0011#) and change the PersoSHA256 flag, but the NETWORK LOCK menu only has 2 options:
{1} PersoSHA256 Info and
{2} RAT_FREE_SUPPORITNG ON
I don't have the 3rd point where I can enable or disable the flag.
Is there any way to unhide that option??
Thanks in advance !
I don't think this is possible. Apparently the Straight Talk S4 is well locked. Attempting to change the modem to an older version bricks the unit.
Your only real option is to use Straight Talk for a year then request an unlock from them.
Why am I not able to "enable" WiFi on Samsung Galaxy S4 mobile. Model no. SHV-E300S?
Hello Everyone,
I'm facing a very irritating problem with my phone. Allow me to share some background of it so that its clear.
I stay in Mumbai, India. I recently bought a new Samsung Galaxy S4 (Model no. SHV-E300S) while returning from South Korea.
I have been using the phone for a week and it worked fine until a few days ago.
I'm unable to "enable" WiFi on my phone. Whenever I try to turn it on, it gets turned off automatically within a few seconds. Below are the things I tried but none of them seemed to work.
1. Restarted my phone over 10 times. - No success
2. Pulled out the battery while the phone was ON - No success
3. Pressed *#0011# and clicked WiFi in the Menu section and turned off the "Wifi power saving mode" - Worked for 2 days and then again not working
4. Hard Reset my phone - no success
5. I did not try rooting my phone as I'm unable to do so. Tried Kings Root (through Mobile and through PC) and many other applications but rooting failed everytime.
6. Reset the Wifi settings in the Wifi section of settings - No success
7. Kept Wifi on on during sleep as "Never" - no success
The Wifi button doesnt let me wwitch it off, and I'm unable to do anything. Please help me with your expertise if anyone has a solution. Please find the details of my phone below:
Samsung Galaxy S4 LTE
Model no. SHV-E300S
Android version: - 5.0.1
Please help......

Ratish

This is a hardware problem or a problem within the kernel. But you say that you did a hardreset so I think it is a hardware problem. You should bring you phone back to the store and let them fix it

Probably hardware failure. If it was software then it wouldn't work at all. But it worked and suddenly stopped working, so it's hardware.
I have root, and dialer codes do not work. How can I access and change network mode on this version?
Thanks
