SIM card not recognized

[PavelCzechRep]

After flashing Xiaomi.eu when I insert SIM card the phone does not recognize it. I did try several SIM cards. Even when I try to switch on eSIM then it says it cannot be activated.

Is it some problem with modem image?

If you have a global Xiaomi 15, you would need to follow this :

HyperOS 2.0 - HyperOS 2.0 STABLE RELEASE

DADA_modem_global_A15 install in fastboot: 1. Unzip the ZIP file on the PC 2. Connect the mobile phone in fastboot mode to the PC 3. Run the installation with the "instal_modem" script (select the installation script according to your PC OS) 4. wait for the mobile to reboot into the system 5. done

You are my lifesaver! Many thanks. It works.

Does that mean that from now on this has to be applied after every Xiaomi.eu update?

Yes, exactly. Or remove the "modemfirmware.img" file from the ROM before installing the update.

I'm having a similar issue on Xiaomi 13 ultra. Can I just flash the A15 modem firmware in TWRP from the global ROM with Xiaomi.eu hyperos os 2?

Why correct modem firmware is not included in ROM image?

Why correct modem firmware is not included in ROM image?

It is the correct modem firmware, but for the China model.

Yeah but as we know bootloader in Chinese model can't be unlocked (at least yet), so actually everyone has to flash global modem firmware manually.
Is it possible to replace files before flashing ROM?

 

[gogocar62]

Yes.
As I wrote earlier, you can delete the "modemfiemware.img" file before installation/update or replace it with the version of your choice. Both are possible.

He is probably asking whether the actual Xiaomi.eu ROM can be provided with Global modem img?

He has a point that no one will actually use the current Xiaomi.eu ROM "as is" because no one has unlocked Chinese version of the phone. For Xiaomi 15 Global (that is unlockable and is the only device that can use Xiaomi.eu ROM) we will have to do this shuffle you are describing every time the new ROM will come up.

This is not the case. Last year, many users had the CN 15 model series unlocked.
Although it seems that since the introduction of bootloader obstructions, xiaomi.eu users with Global devices will significantly predominate.
