[Q] Xiaomi Mi2s - No cell signal after IMEI restore. topic

Hi.
I have a Xiaomi Mi2S that doesn't connect to any cell networks.
I'm using CyanogenMod 11 nightlies, and after an update the phone lost its IMEI number. I had taken a backup of the NVRAM using EFS Professional, but when I looked for it the files where 0 bytes in length :( (probably a hard disk problem on my computer)
After trying a lot of stuff (installing stock MIUI, putting the phone in diag mode and installing a bunch of drivers), I managed to restore the IMEI number, but the phone still can't connect to the network.
I have tried a SIM from another company and it doesn't work. And my SIM works correctly in other phones, so I think that is not a SIM problem.

I don't know what to do... I tried flashing different ROMS, tried flashing a new baseband radio, but I can't get it to work! Is the phone lost???

Can anyone help me? I would appreciate it very much!!!!

[Q] getting crazy installing CWM on Xiaomi Mi2s topic

Hi to all,
I am a very newbie in modding Xiaomi Mi2S and with this forum.
I want to install Wiui V5 KK on my Xiaomi Mi2s 32 GB. I try to install CWM from myRecovery but it doesn't work at all because, when I press Volum+ and Power button my device boot in MyRecovery. I read in this and other forum thata there is a known issue from september 2014 and I have to install another way CWM. I try to use MyFlash but it doesn't work.
I read the thread started by Wajk "[4.4.4][ | WIUI | ][ 4.8.29 | AROMA ] - MULTiLanguage | v5 |" but I am not able to solve my problem (maybe i don't understand) :confused: :o
Could you redirect me to a simple tutorial or guide for newbie who wants to install and use CWM? I hope this is the right thread.
Many thanks in advance
