The tutorial for flashing MIUI on MOTO XT912 is as follows:

Note: The latest porting package is currently version 2.10.26, which must be used in conjunction with the MIUI XT910 official package version 2.10.26. Never mix different versions.

Three-network universal switching method:

1. Change the card. Remove the old card and insert the new card. There is no need to enter airplane mode when changing cards, they can be plugged and removed directly. After changing the card, the signal will be lost or it will show no service.

2. Switch. "Settings" -> "Mobile Network" -> "Network Mode", there are 4 modes: Telecom 3G/Telecom 2G/China Unicom 3G/China Mobile 2G, select according to the operator of the mobile phone card.

3. Restart. After switching the network mode, you will observe changes in the phone settings and signal. At this time, you can and must restart the phone.

After the restart is complete, the phone switches to the new network mode. Moreover, this mode is written and fixed, and the last network mode will still be used when restarting in the future.

Related instructions:

1. If you are using my transplant package now, you only need to refresh the transplant package and then restart. The phone will continue to use the original network settings.

2. If it is a new installation or restarting after dual WPIE, the system will default to CDMA/EVDO 3G (China Telecom) network mode:

2.1 If it is a telecom card, you can directly use the default telecom 3G mode, or switch to 2G mode and only use the 1X network.

2.2 If it is a China Unicom card, you need to enter "Network Mode" and select GSM/WCDMA 3G (China Unicom) mode.

2.3 If it is a mobile card, you can switch to China Unicom mode (the system only uses EDGE 2G), or use GSM/EDGE 2G (China Mobile) mode.

3. Because it will be unstable if used directly after switching, be sure to restart after switching to different network modes. However, there is no need to restart when switching between Telecom 3G and 2G.

4. If you upgraded from another MIUI version, it is best to remember to double WIPE to ensure system compatibility.

Bottom package requirements:

Motorcycle official version 4.0.4 211 or 215 bottom package.

Flashing process:

1. Download MIUI official XT910 ROM package. Download the corresponding version of the three-network universal XT912 transplantation package. Copy the MIUI official package and ported package to the external SD card.

2. Install RazrICSBootstrap or BootMenu on the base package. Run RazrICS Bootstrap or BootMenu to reboot to recovery and double wipe.

3. Flash MIUI official package. Do not restart your phone and proceed to the next step.

4. There are two situations when brushing the transplant package:

If you have not flashed this transplant package before, or you have used RSD to flash the base package again, you need to pull out the mobile phone card, flash the transplant package, then reboot to the desktop without the card, return to recovery again, and flash the transplant package again. Restart the card. Only then will 3G take effect.

If you have flashed this transplant package before and have not used RSD to flash the base package again, you do not need to pull out the mobile phone card, just flash the transplant package and then restart.
