Quattro with Emergency Calls Only, Please help !

Hello All,
I have a Samsung Galaxy Grand Quattro (1 year old), which suddenly started showing "Emergency Calls Only" message with both SIM slots. No matter what SIM is used new or old or any provider it simply dont connect to netwrok. Other symptions are:

• Singal strength is good.


• Shows all available networks in manual search.


• IMEI is valid and not stolen or spoofed. imei info shows everything alright.


• In status shows Network = Unknown, Service State = Out of service

Things I have tried:

• Factory reset, hard reset from recovery, data wipe etc.


• CWM with custom roms like Trans-K and TransWin


• Rooted and changed CSC type from INS to INU


• Installed latest official firmware from SamMobile

But nothing helped till now. Please suggest what to do now. Service provide says problem is with your phone and SIM is perfectly fine works with other phones.

Thanks,

emergency calls only

Hi all,
sorry if this is posted in the wrong place, im new here!
I rooted my phone earlier today with LiquidSmooth rom 4.4.4 and since doing so ive lost all signals (wifi still works)
before rooting with that however, i tried another rom which i didnt like and it downgraded cwm to an earlier version and i think i may of messed about with the field test setting without realising.
ive got everything back up to scratch but im still without a signal and can only make emergency calls

can anyone help me out?

thanks in advance

LG Optimus L5 610 / 612 (f) - UNBRICK - Emergency Mode Problem

Hello! Same problem...

My L5 is making me crazy... It has CyanogenMod 10 nighlty. A friend of mine was using it and he tried to install the GAPPS after he did a factory reset. I have no idea what guide he used but it got soft bricked... It's constantly showing a "stopped working" message and after a while reboots by itself.

I tried to do a factory reset but it always returns to the same point, same apps installed, everything like the reset never happened. I even used CWM to reset it and it allways goes back to the same recovery point.

After a while I decided to flash a stock room but here's the problem: I can't get into emergency mode.
After reading ALL post about it I found that there's at least three ways of entering EM, (1) down VOL and plug in usb cable without battery; (2) down+up VOL and plug in usb; (3) down+up VOL + power botton.

Conclusions:
(1) - gives me a screen full of code like a command line
(2) - White screen
(3) - White screen

I've read ALL the unbrinking post on the internet, including xda, and none of them helped.

The KDZ Updater never recognizes the phone. I installed all the drivers but everytime I plug in the phone it installes the same LGE MTP drive...

Can anyone help, please?!

How to enter Emergency mode? How to flash another rom?
