  1. Hi,
    What do I do if the phone is in recovery mode, inside twrp, in \apply from adb\, and after I do all the things you mention above, I get an error at the moment of copying the .zip file saying there is no device connected?
    And yes, it is connected 🙂

  2. What if my phone cannot get into the settings and enable the USB Debugging because the System UI is messed up, can I still use that adb and replace that System UI APK using my PC?

    • You will not be able to replace the System UI using ADB without enabling USB Debugging. But if you try to make a flash-able zip file for the System UI then you can definitely flash using Recovery. Hope this advice helps you in fixing your device.

  3. Thank you Mr. Alpesh, but seems like my phone is not flashable, because i’ve got a myphone(brand) My25 (model) and not a samsung or HTC, anyway your reply is helpfull..

  4. please help me my device is kata i3s and im a tech newbie it is softbrick(i think?) i try to root it using kingoroot at first it ok but when i turn it off and try to open it again it stucks only on the kata logo

  5. I rooted my phone to install Purenexus rom bt TWRP, i followed every steps of what they said, my phone went soft bricked, it remained stucked on the Google Logo, I downloaded the stock firmware of my phone and flash it the way you said, that worked perfectly man, hats off, Sincerely….Nexus 6P

    • Maybe your device is not detected. Make sure you have selected ADB Sideload or Install Zip from Sideload option. Once selected connect it and type adb devices, if it lists devices then your device is properly connected. If it is not, then install USB Drivers and ADB and Fastboot Drivers on your PC.
