Hello,
I have installed the latest snapshot of CM and everything works fine other than not being able to get mobile service. My IMEI reads unknown and no sim card is detected. I have tried multiple times to wipe and install and still nothing. Any help?
Hey guys,
in the beginning, sorry for my bad english (native german). I have a problem with my I9295 aka S4 Active. Since the update to 4.4.2, my phone gets thrown out of the network. Wlan and Bluetooth is fine. Now I flashed the official Samsung DOB4 firmware. Yes, I've downloaded the file multiple times, and the md5 sum was always right. After I flashed it, I was very happy because my cellular network was working again, I could make some calls, etc. But after 20 minutes, it started again. No network. Well, my IMEI was null, and to fix it I had to root. After rooting, my IMEI is there again (yes, the right one) and everything worked fine and was still working, up to yesterday. IMEI still there, baseband too, everything seems fine, but I can't get network. I have to reboot multiple times to get it working again, after that it's working maximum a day, after that, no network again . Atm, i've flashed CM12, but the error is still occuring. I'm very desperate, I hope somebody can help me.
I have a quite similar problem:
My I9295 loses service randomly. Happens quite often.
When I try to go to Settings/More Networks/Mobile Networks I am told "No SIM ..."
SIM is in and had been active. Phono tells me I have network reception.
After reboot it works for an hour or 20 minutes or whatever it wants to.
Sometimes it reconnects after a while, sometimes not.
When I leave it on during night netx morning reconnect works only via reboot.
SIM reader had been replaced.
Problem persists with genuine 5.0.1, with this one: [ROM][Official Nightly CM12/Unofficial CM12.1][5.0/5.1.1] builds for I9295
and WizCyan ROM.
Any suggestions?
BTW I use a TWRP recovery

Enjoy
Thanks for the hint.
Not sure if I get this. The problem was also there with the genuine Samsung ROM (lolipop)while the thread talks aout losing modem function after flashing custom ROM.
About previous I am not sure as I bought it used with 4.2.2 on it.
I updated to 4.4 and then 5 OTA, all genuine.
Only because the mobile kept on losing network I switched to custom ROM, but the problem persists.
At the moment I use the Pac-Man ROM 5.1.1 where it seems to be more stable.
Strange!
@augek
The linked thread isn't only about custom roms - you can end up with partly flashed baseband on genuine if you don't power off before download mode and flash using Odin.
Was the replacement job of SIM reader done by a qualified person?
Following your Suggestion i flashed the genuine lollipop with odin. Yes i switched of Prior to flashing.
And Yes the Person Who did the card reader Job is qualified.
Still the Problem persists.
So to me the question is if the Firmware (driver) is the Problem of my sim card. The sim i tried on my s4mini and doesn't cause Problems so far as far as i noticed.
P****es me of somehow.
The sim card(which was inside the phone when i was flashing magisk) is working fine on other mobiles and other sim cards are working fine on this mobile
and some random broadcast message keeps on coming
why is it happening to this specific sim card.
I installed official rom, but the problem remains.

Hi guys! Randomly my mi 9 stopped recognizing the sim card. When the sim card is inserted there is also no wifi, when you remove it the wifi can be turned on. Have tried everything, hard reset and then Android setup not working also!!! After rebooting several times, sim in , out, in and out, different sims, rewiping data, nothing seems to work. Back to stock MIUI 11 not working. Updating to the latest 12.0.4 also not. Any ideas? Living in the US with zero support, so any help would be great. Thank s in advance!
