I rooted the phone with Unlockroot (worked), and then i used CWM to install the MIUI.rar from sd. After that i installed the gapps and rebooted. Now the phone won't go on, everytime y press power button the phone buzzes and a green light goes on for one sec. This process goes on forever...
Now im trying to get into flash mode or fastboot in Flashtool beacause i believe it's the only thing i can try right? None of them is workin atm, in the flash mode i dont know what to open as a tft (the rom was .rar) and when i try Fastboot it says "Device Status: NOT FOUND" and " ERROR - This action can only be done in fastboot mode" which i think indicates that the phone can't get into that mode...
The only thing i'm sure is that i don't have a clue of what to do...
I hope you can help me fix this mess cause the phone is new! i'll be reading some more posts in case i find the key! Hope i gave you enough info
Looks like you don't have drivers installed. An easy way is to install Ubuntu on your windows (no need to completely change Os, Ubuntu installs on top of windows). Ubuntu connects to fastboot with no errors.
Now all you need to do is install android sdk.
Open the zip file containing the ROM, and put boot.img in /android-sdk/platform-tools/
Open terminal on Ubuntu. Connect phone with fastboot. Type
Sudo fastboot devices
Now if you have an unlocked bootloader, continue. If not, message me.
BOOT. IMG AND FASTBOOT FILE MUST BE IN THE SAME FOLDER.
If you have unlocked the bootloader and get response from the above command, then type in Ubuntu terminal
Sudo fastboot flash boot boot.img
Sudo fastboot reboot
Now you can enter recovery and flash the zip.
Again, if you have problems, message me.
