Disclaimer: I'm not a good writer just bare with me, Due to people asking me of how i unbricked my Dead Android, I decided to create this tutorial.
Many time you hear lots of people looking for solution on how to unbrick their device. i use to be part of them when i bricked my tecno l7 from soft brick it entered a higher level of bricking that is called hard. Alot of people enters this problem trying to flash higher custom rom that is not meant for their device some through kernel. while some from soft brick it enters a higher level on bricking. where your device doesn't come on, no vibration, black screen,cannot be detected by pc (no sound of connection on your pc). expecially when there is no preloader in your device. this means you are having a DEAD phone. here I'm going to show u how to flash preloader.bin and your device rom to your dead android. this tutorial is strictly for hard bricked device also if your device is soft bricked you can also try it.but this was how i unbricked my Dead Android
requirements:
1.PC

2.USB CORD

3.SP FLASH TOOL LATEST VERSION goto http://spflashtool.com and download latest version

4. MEDIATEK VCOM DRIVER (i.e if you enter sp flash tool official site u can download this driver from there and there is even tutorial on how to manually install mediaTek VCOM driver there just load the video)

5.CUSTOM ROM OF UR DEVICE goto www.romkingz.net to download any phone rom(with scatter file and preloader.bin)
Then u are good to go.

=>first connect ur phone to ur pc: if ur pc doesn't make sound of usb connection. then start pressing volume key up or down on ur device till u hear sound on ur pc (puuchuunpuu) and also ur phone will start vibrating but if it doesn't vibrate keep on pressing volume key up or down as many times as possible till ur phone start vibrating then it starts connecting and disconnecting in ur pc keep calm head to the next level

=>second manually install mediaTek VCOM driver: this driver help computer to detect a bricked device. firstly disabled system signature verification I'm not going to show u how to do it now just Google search it then after successfully disabling signature then install the mediaTek VCOM driver from your pc device manager. for those who don't know how to install it just search "how to manually install mediaTek VCOM driver" through Google search or through havotek or goto http://spflashtool.com there you will be shown how to install it u have to scroll down to see how to install it on the site. after successfully installing the driver through device manager u might see a yellow sign don't worry just head to the next level. in your device manager via potable device you'll see your device name as the driver u just installed (to confirm disconnect and connect your device)

=>note: your device will not be stable it connects and disconnects on your pc. don't worry you are on the right track.

=>next extract your device rom to a folder you'll remember and also extract flash tool latest version open sp flash tool go down to flashtool.exe upon it then enter scatter file. a folder will open then locate where you kept your extracted custom rom then open locate scatter file.txt and open. it will then open in sp flash tool everything in ur rom will be loaded in the sp flash tool next untick everything there because when the scatter file loads everything will be ticked so just untick everything except the first one which is preloader.bin because your pc won't be able to flash the custom rom into your Android without first flashing preloader or else it will not be stable connecting and disconnecting. rom won't be able to install breaks half way. preloader.bin help ur phone to boot and also helps system to detect your phone without disconnecting.

=>make sure u disconnect your device from pc (if your battery is removable then remove your battery but if it's unremovable then just continue don't do any foolish thing trying to remove an unremovable battery you'll just distroy your device) i repeat make sure you untick everything except preloader then press download after clicking on download then next connect your device then it will start loading you'll see yellow stuff under loading if it loads successfully then you are good to go but if it shows 100% with red line under and something comes up saying "PMT error download rom" don't panic just click on format at the top when it enters format page then press format then sp flash tool will load successfully now it will not give u PMT error again. Then back to download page click download if it doesn't load remove your USB from your pc then put it back (make sure u disconnect before clicking on download after clicking on download then connect your device back to your pc) then it will start loading then when it reaches 100% you will see a green mark showing you it was successful. then your device will no longer connect and disconnect your device will now be stable.

=>Next on your sp flash tool now tick everything there except your preloader because you have already flashed it. now press download if it doesn't start loading again just do the same thing remove USB and connect again then the rom starts loading u will see a yellow stuff loading wait it takes up to 10 minutes to load. when it loads finish a green tick will pop up showing u it was successful. then disconnect your device from pc. then try charging your device. your device will start charging let it charge for sometime then power it on it will take some time to fully boot. that's all start flexing your phone.

=>credit to me: i did this tutorial without looking at my pc. just with my head and experience. didn't copy from any blog or site. I'm not a pro just a fellow nairalander. if u have any complain or suggestion or u want me to put u through. reach me through nestic244@gmail.com.
