I wanted to downgrade the firmware on my galaxy S4 I9500 from BMG9 to BMG1 for the battery life because even when I bought a new original battery from samsung still the drain is high but the phone doesn't get hot as before. When I install the older firmware, the phone loses the mobile network signal and doesn't connect even if I choose the network manually so I have to reinstall the BMG9 again for it to work, can anybody help me with this situation? Thanks
Edit:
I found a solution through flashing the MG1 firmware with MG9 modem through odin but will this work as MG1 or the modem is controlling all the battery drainage and cell signal. I also believe that the problem came from a faulty imei??

Hello there,
I installed the latest CM from the official website and now I have problems with my signal.
Most of the times, the phone can not find a signal. Sometimes it catches it, but it will last for 4-5 minutes. If I go into flight mode and come back, the signal will be there for 1 minute. When I don't have signal, there's the R near the signal bar (Roaming).
I haven't changed my modem with the new installation (I9505XXUAMDC). I am on the O2 / TESCO Mobile network in Ireland.

Hi mate ,
I assume you have an I9505 , there is know issue with modem/bootloader incompatibility you may have to use a modem wifi fix or upgrade the bootloader to use the newer modems

Hi mate ,
If i am not wrong that is a 4.2.2 modem , if you don't worry about the warranty anymore i would get the full package
MODEM / LTE / BOOTLOADER
I fixed it by installing the modem+Wi-Fi fix. I was afraid of installing the bootloader, as if something goes wrong when installing the modem, it can be fixed, but I don't think it's the same with the bootloader
Hi.
After updating Danvh's lolipop-rom to the latest version, I lost my signal and wifi. When I force my phone to use 2G (GSM only) in network-settings, everyting works normal.
But of cource I want the speed of 3G and 4G when using internet!
Sometimes (not often) 3G works.
Sometimes the phone says it has signal, but calls, internett etc don't work
I tried to flash the latest modem (XXUHOC6), but no luck. Have also tried modem XXUGNK4, XXUHOB8 and XXUHOB7. I tried to go back to the older version of the custom rom, but no luck
I have now downloaded the latest official stock rom from sammobile. But same problem with stock rom.
Any suggestions?
I have IMEI
Sorry, I have the same problem and I am still searching for a solution. And I have been trying everything as you and no solution. Sometimes I think is a hardware issue.
Very frustrating :S
Hope to find a solution soon.
