Can't Install The Rom From Some Reason, Appreciate Your Assistance

Aug 8, 2012

I have a Redmi 1S WCDMA which I cannot install the ROM on.
The device is on a Chinese stable 45.0.
When I go the the updater, the device starts the installation on recovery but gets stuck after a while when it is on 98% with a "failure" message.

After that I have to revive it with Miflash back to stable 45.
What's wrong? Why can't I update?

I tried going to MIUI6 and 7 afterwards, no matter what I try, it fails.
