[Q] SPFlash-Tool after bricking

Hi,
i have bricked my P780 after flashing with new firmware. Now the Phone is dead with black screen and doesn't start after pressing Power button. After a few trials with SPflash (3.x) i recognized that SPflash had a problem with reading the Scatter-file i.e. the adress mapping. The adresses were set for all areas from 0x0000 to 0x0000. When flashing the phone i didn't see that and i think this is the reason for the dead phone (stupid old man
With Spflash 5.x the Scatterfile was read correctly.
Anyway: Now the phone was detected by the Win7 device manager as Mediatek USB Modem but it works not correctly with SPflash (3.x or 5.x).
I could neither download new firmware nor format the flash. I get always the error: "BROM error DA download to Baseband SRAM failed".
Sometimes i get the message that the power up sequence was problay to short and the bootmonitor sequence didn't work.
Both states are reached after pressing the reset button on the backside when the phone is connected to the PC.
Is there any chance to get the phone working with SPflash again or do i have to use a JTAG-Tool ( if there is one for Mediatek-chips)?

Hi. First look on the box of the phone. Iff there is something with a date that is something like 03.2014 or more like 09.2014 look what you must do:
1. download SPFlash Tool from here. This are the correct tools for Lenovo P780. DO NOT USE OTHERS.
2. now download the preloader file from here and the drivers from here. And yes, you must reinstall the drivers because your preloader is messed up.
3. unzip preloader file, go to target_bin folder and delete existing preloader(preloader_prada_row.bin), and add the preloader you downloaded, and delete any file from target_bin directory with the name Checksum.ini.
4. now load scatter file from ROM directory(should be target_bin directory)
5. check DA,DL WITH CHECKSUM (NOT OPTIONAL)
6. press Firmware Upgrade button (NOT DOWNLOAD BUTTON)
7. now just now plug usb cable to your phone.
8. firmware flash should start.(some red and other color lines should appear)
9. iff the firmware is not starting remove the back case of your phone and hold pressed the little red button from the right side, for about 20 seconds then release. All this must be done with cable pluged in to your phone.
10. after flash is done a green circle should appear
11. disconect your phone and power on your phone
12. lenovo logo should appear. then you should be pacient because it will took some time before android boots for the first time.
13. Good luck. Hope This Helps You. If not post here again.
Hi stympy,
sorry for the delayed feedback but i had no time to test it until now.
But you where completely right! It was the wrong preloader and the wrong drivers.
Now the phone is running again! Thanks a lot!
Best regards!

Thank you very much @mottaM
Your solution saved my redmi 6a. I had some problems/errors while using spflash tool but after reinstalling drivers and changing the usb cable my problem sorted out.
Also, the new spflash tool is quite confusing for me so i used v5.2152
SP Flash Tool v5.2152 for Windows - MediaTek Flash Tool
Download SP Flash Tool v5.2152 to flash or install Stock Firmware ROM (Flash File) on the devices powered by Mediatek Chipset.
