Hi all. I tried to find some help in a spanish forum I usually visit, but is no help, I think the case I have is quite rare and strange. I have never read before about.

2016's black friday I had a friend searching for a phone, and I achieved a quite cheap Mi5 for him. Is 3gb ram and 32gb version. After my experience with some other Xiaomi (mi2s,mi4,mi4c...), I didn't hesitate to advice the mi5.
It came with a false Xiaomi rom, I unlocked the bootloader, installed TWRP and flashed xiaomi.eu's latest weekly rom (6.12.15).

All was correct and my friend was a happy Mi5 owner... until 2 days ago. But on wednesday wrote me complaining that had no signal on the phone. He wasn't able to connect to network. No able to call, receive a messaje or connect internet. Yesterday, I went to help him, and tried diferent things in order to fix the problem.

1- I tried his Sim card in my OP3. Caught signal, even 4G. So I discard any sim problem.
2- Wipe cache. Same, no signal.
3-I tried my sim on the Mi5. Firstly caught signal, didn't let to call. No internet conection. After a minute, lost signal.
4- Factory reset. Same, no signal.
5- I downloaded last weekly rom, 7.1.19-20. I wiped everything except internal storage and installed new rom. But still continues with no signal.
6- I consider is Imei's problem, but it has the Imeis. (Look *#06#)
7- I let the phone for today evening or tomorrow, was late. I'm going to sim card company to talk and try to find out what the problem could be.

I don't think the Imei could be blocked, just my friend, I and the seller had the number.
When trying to connect manually to an antenna, the phone finds the different ones around, but doesn't connect. I don't think is hardware problem. He said me, had no drops with phone.
He can use wifi connection.

Can anyone help me?? I'm quite desperate, I think I've tried everything I know, and had no results.

Sorry by the way for my english, I think you will have no problem to understand, but I know there will be some mistakes jejej

(Do you just tried to use warranty?? We have just talk to the seller, let's see what he offers.)

lo compre por *******...me dijeron que lo enviase a China....y la verdad que paso porque me han dicho en otros forums que no hacen nada y es muy probable que se pierda.

Lo tuyo bien puede ser algo mas simple. Lo mio creo que es mas complicado, tipo hardware quemao en parte o robo de Imei. No se decirte. Porque no vas a unos paquistanies? Yo en el pueblo de alado tengo unos que cambian pantallas y arreglan este tipo de problemas por pocos euros. Y puede que te sirva.
