Hey Guys, I have a simple question..Since most MTK Phones have many variants per model,For instance Tecno W3 has Eight Variants,eg
W3-H806A1-M-161031V90
W3-H806B1-M-EG-160721V8
W3-H806B1-M-EG-161012V12 
etc
and sometimes you find a Hard Bricked phone in that you cannot boot into recovery to get the Build number which can help you download the correct firmware to revive it. Now here comes my question,is there a way one can just flash the Preloader ONLY on the phone to test untill you find the correct firmware (By using the Preloader Minus the rest of the firmware file )or you must just download the whole firmware file and flash it..?


for the case of Tecno W3,Download only the preloader and scatter files for all the variants and test them till you get the correct one,Is it Possible?

It is tedious ,but possible
It is tedious cos you have to find the exact scatter file to match the preloader you are trying to flash

Yes its possible and that's why we embarked on the Individual Files project. You should however be aware of some things.
The process of downloading only preloader and scatter is for you to know (ahead) which rom you'll be able to flash and which will give a mismatch error; thereby saving your data instead of downloading a full rom only to get a mismatch error.

Now, just because a rom doesn't give you a mismatch error (when testing scatter + preloader) doesn't mean it 100% guaranteed to work. It just means you'll just be able to flash the firmware to your device (without getting a mismatch error). This doesn't mean the phone will boot or work fine after flashing

Its still trial and error (unless you know the original build number) so the preloader+scatter flash is just to narrow down.
I should also mention that recovery isn't the only way to read build number. There are other methods @ https://www.hovatek.com/forum/thread-16005.html
