dismantle or disassemble the phone and look for two points on the mother labeled kcollo and ground....soldier a wire from kcollo to ground and force write a working preloader from a working phone or look for one within hovatek forums...Thanks...Please take your phone to a technician if you aint one.

If you're certain its not due to a drained battery then refer to https://www.hovatek.com/forum/thread-11802.html

I did all steps, then i start flashing, SP flash tool stuck on 0 percent and shows error : S_BROM_CMD_STARTCMD_FAIL (0x7D5). [BROM] Can not pass bootrom start command. Possibly target power up too early.
What i need to do now?

What i need to do now?

* Ensure the battery is well charged
* Take out and reinsert the battery
* Try using a different USB cord, port and PC
* Run Flashtool.exe as an Administrator

I think SP Flash tool will have a problem writing to your chip. I recall doing some work on a phone with your chip.
What version of SP flash tool did you use?
