My Innjoo I2 was in strange behavior (random reboot / random shutdown) because it was the end of life for the battery
So, I tried to make a factory reset – after that mobile didn’t again and no charging indicator
I got a new battery but didn’t power on either
I tried to flash stock firmware with sp flash but every time I got error 4001 no response
Windows detect the phone correctly and sp flash working correctly (tried with other phone)
How to unbreak the phone???
are you sure of the firmware you are trying to flash?
Are you able to read the phone on miracle?
If you are sure of the firmware, try these fixes for the sp flashtool error 4001
Error 4001
Message: S_FT_DA_NO_RESPONSE or Da didn't send response data to FlashTool!
Meaning: SP flash tool is having difficulty communicating with the device
Solution:
Change the USB-port
Run SP flash tool as Admin
Ensure to install the correct drivers (see https://www.hovatek.com/forum/thread-440.html )
Try another PC and USB cord
Ensure the phone is switched off with a charged battery inside when connecting to the PC for flashing
I tried all steps of SP flash above without any success
about miracle I searched for it and run it that is the results I get
Set MediaTek USB Port (COM3)
Connecting to Phone,Wait..
Connected to Phone.
