I received my Xiaomi hongmi Note 2 (1.7 GHz version) from merimobiles.com today. The phone came with version (17) of MIUI and it wanted the latest version (23). Therefore, I tried to upgrade the phone and downloaded the latest ROM from the MIUI site. But I accidently,downloaded the ROM meant for TD-SCDMA( china) version instead of WCDMA(international) version. After installing the upgrade, i came to know that i had installed the wrong ROM. However, the phone is booting and working properly except that it cannot make and receive calls. Before upgrading the ROM it was working perfectly and signal reception was also fine, but now it does not show any signals at all. Please............. help me, to install the original ROM. Thanks in advance.
