Thanks Danillo Caballero Q. Followed the above No SIM fix and yet no IMEI/Baseband ? A. Follow this fix, this fix is for the worst case scenario. Only for those who know what they are doing 



1. Make sure phone is working on your stock ROM (you can make/receive phone calls and that IMEI is correct). 2. Use "MTK Droid Tools" 

and make NVRAM backup (you'll get one .BIN and one .TAR file). 3. Use "SP Flash Tool" and make backup of your PROTECT_F and PROTECT_S partitions (using "Readback" tab). This is just in the case of the worst case scenario. 

4. Flash custom ROM, let it boot, then go back to recovery and install Gapps and Kinguser. 5. When the phone boots again go to ADB shell. 6. Type "cd /protect_f" and then when you're inside that directory type "rm -R *". 

7. Type "cd /protect_s" and then when you're inside that directory type "rm -R *". 
8. Copy "nvram" directory from your NVRAM back to the "/data" directory on your phone overwritting all existing files (do NOT first remove "nvram" from your phone, just overwrite existing files). 

9. Wait few seconds and your SIM card should be detected altogether with your baseband. 10. Restart your phone to confirm SIM card is working. 

- Major thanks to Amir Ahmetovic, Abdullahi and Dechronic Q. Camera not working even after using the above camera fix in this post in Build 1 of CM 12.1 Beta 7 For MT6582 ? A. From a CM 12.1 ROM or CM 12.1 based ROM in which camera is working copy all files which have the word "libcam" and replace it in beta 7 build 1 and camera will work. Make sure you reflash the whole ROM again. If you do not have a working build then visit the post below and download a flashable zip Visit : Flashable Bug Fix ZIP If you have any more questions comment down below I will try to fix them. And please do not report about any bugs saying please fix this. A lot of hard work has gone into making these ROMs. I already know what bugs are in the ROM. I will try to fix them and give a updated ROM link. Till then do not report any bugs. Just booting this ROM in your device is most important.
