Hey guys, my friend brought to me a Coolpad F2 (don't know where he got it from) with a micromax rom installed which had network problem. On researching I came to know that Yureka is a rebranded version of Coolpad F2. So I flashed yureka official firmware. But still I couldn't solve the network issue. Another weird thing about this phone is that there is only one imei number printed on the phone and the second SIM slot doesn't detect SIM. The phone works perfectly on 2G network, data keeps disconnecting on 3G and no signal at all on 4G(Jio). I've tried everything and every tricks I could find on the internet but no luck. My only thought now is trying a different baseband from another similar phone (I couldn't find modem file of coolpad F2). Any suggestion would be much appreciated.

Hello! I have a big problem that i cant find a solution. I opened engineered menu (*#*#4636*#*#) and from phone information i changed by mistake cellular band to usa(gsm-850/PCS-1900...) Then sim1+2 now has only LTE band working. Not 2G/ 3G. I make hard reset but not solved the problem. Please help me!
You'll have to flash a baseband (modem) file. That's what works for Moto phones. Might work here. Or simply flash stock rom.. wiping all.

I've sent to both of you private messages. If you haven't recive them, let me know.
Same problem here up
Did you flash a device specific stock ROM for YOUR exact variant? There's issues if you flash another carrier or countries ROM sometimes. The RIL won't be set properly along with various other device/region specific properties

Hello Guys,
I bought an S4 and I discovered that I was scammed (it was the sprint version and not the GT-I9500 as it was indicated on my about phone tab). It comes with 4.4.2 and everything was working fine (the only things that bugs me was that I was unable to receive updates). Recently I encountered some little issues so I decided to install a new ROM. I tried the Vanir and Commotio ROM and for a moment I was super satisfied (it was an amazing experience). However after putting back my SIM card, each time I try to deal a call, I got the error "mobile network is unavailable". I thought it was an issue from the ROM I used so I tested the LineageOS and same issue. Finally I tested the STOCK ROM Lollipop and the same issue again except this time the WiFi does not work. Now my phone is completely useless, so can anyone help please ?
PS: When I go to settings->about->status, everything about the SIM info(network, my phone number,...) is set to unknown. the IMEI is intact (non null). IMEISV is 00.
