New Networks Not Working After Updating Redmi 3 Pro

[Redmi3ProBaby]

Yesterday I updated my Redmi 3 Pro from a fake ROM (which worked) to a Official ROM using EDL mode. Since then, Mobile Network does not work with any ROM I load. Right now I have the newest rom installed (xiaomi.eu_multi_HM3_7.10.26_v9-5.1) but still does not work.

- At the top of the screen appears an Icon of a SIM card with and X, signaling "no network".
- If I try to call a real number, it tells me to disconnect airplane mode before (it's already disconnected, obviously)
- If I try to access mobile internet, it does not work
- The IMEI is not lost (appears when I call *#06#)
- If I click many times in the kernel version (in configuration/about my phone), the Hardware test sees no problems with SIM
- If I call *#*#4636#*#* and go to phone information, the prefered network is LTE/GSM (which is correct)
- I manually configured the APN following my provider's directions, but it does not work.

Right now I'm a little bit desperate. Could you help me solve this problem and get mobile network working again?

try to select 3g preferred network in sim setttings

Hi!
I selected 3G as preferred, but it did not work. Then I selected 4G and 2G as preferred, but did not work for any of them. Tried to make a call and the phone tells me I have to deactivate airplane mode (which is already turned off). Mobile Internet doesn't work for neither of these preferred networks.

Can someone help me, please?
