Hi!

I didn't noticed that your phone doesn't go to nvflash mode. Try to press the two volume buttons really really hard. My volume buttons got really unsensitive after 2 years. So I am also strugling with my phone to get it to nvlfahs mode.

  1. Go to this thread.
  2. Download AIO-TOOLKIT.
  3. Install AIO-TOOLKIT.
  4. Remove the battery from your phone
  5. Connect the USB cable to your phone while you are pressing volume up & down buttons.
  6. If you haven't installed APX drivers before, then windows will notice a new hardware and it will try to install the drivers for it, but it will fail.
  7. Start AIO-TOOLKIT.
  8. If you already have APX drivers installed skip this step. If you don't have the APX drivers installed, then press "I" (capital i), After that a window will apear. Just follow the instruction.
  9. In AIO-TOOLKIT at the Main menu press number 4.
  10. On the next screen you can decide between the new and old pt layout and bootloader. Keep in mind that whatever you choose you have to flash the correct rom for the correct bootloader+partition layout. So the new MIUI roms are only for the new bootloader and layout, old miuis like the 2.7 is for old bootloader. Here in the developement forum you can find CM10.1 roms which are made for new and old bootloaders, you just have to download the correct one to your actual bootloader. So press number 1 or number 2
  11. Whatever you choosed at the previous step, press number 1, unless you want to do dualboot (two type of andorid on your phone). If you want dualboot then press number 2 and follow the instructions on the screen.
  12. On the next screen you have to choose between 3 cwm version. If you selected the new bootloader I recommend to use cwm 6.0.2.5 or twrp 2.5.0.0. If you choosed oldbootloader I recommend you to use cwm 5.0.2.8 or twrp 2.5.0.0.
  13. On the next screen, after you choosed your custom recovery, type "ok" (without the " marks) and hit enter.
  14. Now the phone is going to be reparititonated and etc... so your phone will work again.
  15. After the flashing ended wait about 10-15 secs then unplug the usb cable.
  16. Reinsert your battery, then turn on your device. It should boot up into the selected custom recovery. If it does not boot up into recovery then turn off your phone and turn it on again while you are pressing and holding volume_down and power button.
  17. Enable usb mass storage in the cwm recovery then plug the usb cable back. Format the internal SDcard to FAT32 then copy the zip file of the selected rom you want to flash (like miui or cm)
  18. Flash your prefered rom
  19. Restart phone.
  20. Done

Do you remove the battery?

Try to enter s/w upgrade mode by press and hold volume down key and plug the usb cable. Then use smartflash to flash rom

I dont really know what drivers did installed succesfully, but you don't need battery to use smartflash or nvlfash. If you want to use smartflash without battery then first flash the .fls file and for the second attempt flash the .bin file.
