Xiaomi 13 ultra no radio signal

[alex369]

Hello,

I would like to thanks the entire community for this enormous work.

I have a Xiaomi 13 ultra Ishtar CN version, i m in Europe.
I installed xiaomi.eu_ISHTAR_OS1.0.16.0.UMACNXM_14.zip version on it and i recently lost the signal radio when i restarted my phone. My simcard IS detected but no signal.

It s a problem well known on this forum. But I tried all the way possible and I didn t succeed...

I tried to flash modem partition a and b with modem.img and non-hlos.bin from global and eea rom.
I Saw on Xiaomi 14 that some people flash modemfirmware but I don t find it on Ishtar.

I reinstalled several times rom with script "install for the first Time".
But I have still the problem.

Could you help me with this problem ?
Thanks in advance for your help.

Alex
