Coolpad Dazen 1 not detecting Sim Card - General Questions and Answers

Hello everyone.
The device i'm using currently is Coolpad Dazen 1
A few days back my phone was not connecting to wifi. So i restarted the device and then along with the wifi problem sim cards were also not detected. Also no audio/video could be played and headphones were also not detected.
I formatted my phone but still the problem was there.
I rooted my phone and installed cm11 nightly. Wifi problem was resolved, but still sim is not detected along with audio/video problem.
I searched the net for any solution but nothing yet
Can anyone please help me out.
I first flashed cwm recovery v6.0.5.1 then flashed cm11-20150406-unofficial-n918st

[q] help: Sim card not detected on gionee p2

I own a GIONEE P2 mobile phone with MTK6572 processor and android 4.2.2 and 512MB RAM. I successfully rooted the phone and it was working fine until my internet stopped one morning and upon restarting the phone, it wrote SIM1: SIM card not detected, SIM2: sim card not detected. I have tried all I could yet no avail as I can't use SIM card in the phone. I used MTK droid tool but nothing could be done, also entering engineering mode with ##4636##, the radio remained permanently turned off and couldn't turn on. I used IMEI tools to rewrite and replace the NVRAM files yet nothing happened. it has been very frustrating trying to find a solution but none found. Please anyone with any idea on how to resolve this issue should please help. WIFI and bluetooth still work fine.
Thanks in advance

Cannot connect to mobile network - IMEI recovered succesfuly

Hello everyone,
Phone: Prestigio PAP 4500 Duo.
I'm getting crazy a little. Lost almost two days for this.
My girlfriend's phone just stopped working 2 days ago, stuck at bootloop. I somehow managed to get some stock Sp Flash tool flashable ROM from russian site and brought phone back to life. But in process I had to do Format (with keep Bootloader only option) and deleted my NVRAM.
I did then manage to restore my IMEI by making MP0B_001 file with my IMEI numbers and moving it to /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001.
So, My IMEI's are now succesfully stored to NVRAM but I still cannot connect to network.
I would use some help.
Thanks all! Cheers,
Bruno.
Edit: Solved. It might seem crazy, but I turned SIM card wrong way....10 times...
