Galaxy S4 CM12 5.0.2: Enable The Service Menu

Anyone know how to enable the service menu for CM 12 5.0.2 on the Sprint GS4? dialer codes don't work, looks like they have to be enabled somehow? :confused:

Want to install CM12 on ZV6 Rooted do i have to do anything extra?

Wanting CM12 on my LGG3, i accidently upgraded to 4.4.2 when it came out and was just today got back to wanting a custom rom, i rooted with the LG Root Script V2.4 and have checked Superuser is on, i go to clockwork mod to look at my recovery and i guess i have TWRP and ClockworkMod Recovery but its a custom one, dont know if its 2.x or 3.x. I also remember when i was first looking at custom roms or maybe flashing back to ZV4 you had to back something up to be working on sprint.

So my question to you is,

1. Do i need to do something with the recovery.
2. Do i need to back up the MIN/ESN/MEID/IMEI or anything like that or can i just straight up install CM12?

Thanks for the help

Wifi won't turn on after upgrading my Xperia V to Cm12

Hello there,

I recently flashed the CM12 firmware (version cm-12-20150906-NIGHTLY-tsubasa.zip ) on my Xperia V device (from stock Android) using TWRP 2.3. Now I have the official Cyanogenmod Recovery cm-12-20150906-NIGHTLY-tsubasa-recovery.img
Everything works well but the wifi. I cannot manage to turn it on.
I also tried this but it doesn't work:

The solution was to simply change ownership back to system:wifi
$ adb root
$ adb -d shell
# cd /data/misc/wifi
# chown system.wifi wpa_supplicant.conf
# reboot

Has anyone had this issue?

Question about cm12

Does cm12 support link2sd and other root functions like mount system r/w? And is there proper recovery mode for cm12?

Galaxy Grand Duos GT-I9082 running CM12 Firmware encountered an issue

My Galaxy Grand Duos GT-I9082 was running the Cyanogen Mod 12 for the past 4-5 months and over a period of time the system started crashing frequently and I wanted to get back to the Stock ROM. I made a factory reset, wiped partitions and wiped delvik cache. I started Odin, got the device into downloading mode and flashed the Stock ROM (downloaded from sammobile 1 year ago) which I have flashed several times before also and which has worked absolutely fine everytime. This time however, after I flashed the Stock ROM, the downloading process started and the process came to a halt after a few moments and the operation "FAILED". I made a reset and tried to flash the Stock ROM file again but to the same result. I made an exit from the Odin, disconnected the device and tried to start it but it said "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again."
Neither can I start the device nor can I go into recovery mode. The phone can only go into the downloading mode right now.
I downloaded other Stock ROMs and tried flashing them but none of them are working. I even tried the emergency recovery in Samsung Kies but that does not recognize my device itself.

Anyone has a solution here?
