SIM service no more working after installation of Cyanogenmod 11

Hi,
I bought recently a Redmi 2 Enhanced (2 Gb)
Code:
Redmi 2 Enhanced (2Go RAM / 16 Go)
HM 2LTE-CU
Networks: TDD-LTE/FDD-LTE/TD-SCDMA/WCDMA/GSM
Android 4.4.4 KTU84P
MIUI 5.8.20 | Beta
Base band MPSS.DPM.1.0.c7.18-00023-M8916EAAAANUZM-1-all15
Kernel 3.10.28-gf3355b2
It was working well with my two SIM cards (Free Mobile, France ; Mobinil, Egypt).
I installed Cyanogenmod 11 (cm-11-20150829-UNOFFICIAL-hm2014811) and gapps (gapps-444-base-20150818-1-signed).
It changed also the recovery for CWM recovery.
It worked fine, but the two SIM's are now flagged "No service". If I try to call a number, the phone asks me to switch off the plane mode, which is already switched off. I switched it on and off back, without any result.
I found a similar problem on this link: /thread-125218-1-1.html on forum en.miui.com
He says: "my redmi was working fine but then accidently my recovery was flashed by cwm recovery so I have flashed my phone with China ROM LINK V6.5.3.0.KHJCNCD because global rom is not working, my redmi is 2014813 so global rom does not works and Now I have got my MIUI recovery back but my both Reliance and Airtel SIM are not working there is a message in both tower NO SERVICE."
He says further : "My problem is solved I flashed my recovery with twrp 2014811 version then installed the latest global rom everything is working fine.​"
I tried it: installed twrp 2014811 and xiaomi.eu_multi_HM2014811_5.8.20_v7-4.4, without getting back my SIM!
I finally used MiFlash to bootflash my phone with wt88047_images_V6.6.4.0.KHJCNCF_20150721.0000.5_4.4_cn_159a7e83ed.tgz.
And the problem is still there: I have no service anymore on both SIMs!
Any help?
Thanks,
Remi

1. Delete lines 10 and 11 in file "flash_all.bat" (lines containing "*MSM8916").
2. Flashboot with flash_all option.

No sim card/invalid sim card issue after flashing into stock rom

I own a Lg G3 sprint ls990.I live in Bangladesh.My device was on android lollipop and it was fine.But due to restart and warming issues i flashed into stock kitkat rom using flashtool.After 91% of flashing a red screen poped up in my device it said "warning; not support qem=0" and in the flashtool app it said failed.But when I pulled out the battery and rebooted my device I saw everything is okay.Then I put on a working sim card and it couldn't detect the sim card.i tried with whole other working sim card but i couldn't detect.I changed my sim slot but that also cannot change the condition.I flashed with other roms but still nothing is happening.When i dial "*#06#" to know my imei it says "connection problem or invalid mmi code".......Now Im badly in need of your help guys.Please,do help guys.

CM13 is not detecting my phone service. but when I revert back to MIUI 8 my phone wil

I bought an Xiaomi Redmi note 3 last month December supposed to be my mom's Christmas gift. I have an Xiaomi Redmi MIUI 7 but the one came was MIUI8.
So I had to downgrade to MIUI 7 then unlock bootloader. - then install CM13. The problem is when I placed her sim card in and try to activate it. MetroPCS said the activation was a success? but the issue was the phone can't detect the sim card and there is no service on the phone.
Stranges part was when I went back to twrp to restore MIUI 8. The phone was able to detect the sim card and I got data service plan.
Does anyone has the same issue? any help please.
im using the rn3 on mpcs and i get service across all roms.

Baseband unknown, and no network connectivity after update to latest Xiaomi.eu ROM

Hello
I have a problem with my Redmi Note 3 (kenzo). After updating to the latest Xiaomi.eu ROM version (7.2.24) I cannot get the sim cards to work. They varies between not being detected at all, and being detected, but not being able to connect to the networks.
I still have an IMEI for both slots, as well as MAC address for wifi/bluetooth, but the baseband version is "unknown". The sim cards works in another phone (and other sim cards don't work in this).
I'm not really sure where to start looking, so any help is appreciated.

I have same on my Kate . Everything working great and it has baseband version -8976_GEN_pack-xxxxxxxxx...... I know its a different file for Kenzo but likely related to file you downloaded. Either you downloaded wrong one(xiaomi.eu_multi_HMNote3Pro_7.2.24_v8-6.0.zip) or the file got corrupted somewhere along the way.
I suggest you do the whole process again.
Have you checked your phone is a Kenzo ?

I am on 7.2.24 and i have no problems as such. I updated it from 7.2.16 via in built Updater app. I have zcx twrp installed. Since you have unknown baseband, my advice would be flash the latest firmware.....If unsuccessful then flash using MI flash tool via EDL mode
