Please help me
My Tecno F1 got stuck in fastboot mode then i found a thread of similar issue @ https://forum.hovatek.com/thread-31301.html. So according to the guide there I looked for the firmware of my F1 phone( F1-VP510EFG-GO-200304V18) . At the Tecno F1 firmware page I couldnt find the firmware for my exact build number but it was written there that F1-VP510EFG-GO-191205V16 and F1-VP510EFG-GO-190119V7 both work for my F1-VP510EFG-GO-200304V18.
So, then I downloaded the one for F1-VP510EFG-GO-191205V16 and i flashed my phone with it. But after the flash my phone wasnt able to boot.
Since I wasnt able to boot up i had to dump an incomplete rom containing recovery.img to see if the flashing changed my build number,so when I checked my build number has been changed to the build i flashed my phone with( F1-VP510EFG-GO-191205V16).
So my first question is if -191205V16 and -190119V7 work for -200304V18, can they work for each other. And what do i do after this please help me.

The F1 / F1 Pro is a pretty strange model to say the least.
I suggest you try the 190119V7 also

Actually after a day i just charged it for hours and it booted up. Everything you said on the many guides I read worked. It is true; the -191205V16 and -190119V7 really work for -200304V18. You don't disappoint. I have learned so much from you guys. I am in your debt. Thank you very much !!
