my device had gone into a boot loop condition where It can't

  • be detected by adb or computer even in fastboot or recovery mode
  • hence, twrp sideload not working
  • can't push files into and zuk is having no sd card

and some other resources might be useful,

  • has twrp on it
  • bootloader is unlocked
  • pc with adb :)

please help immediately.. and thanks in advance,


It appears you have bricked your device if you would have different device I would have provided better instructions however snapdragon chipsets are hard to flash however give this a try Download cynogen os from here-


And install it through your TWRP. In case if you had a backup through twrp you can restore it hope it helps

Without a sd card its not possible so arrange it from somewhere or try QFIL flash tool and stock rom as you have a pc.
