This solution is for dead units only after flash, but if in case buhay ang unit at logo lang naman there's no need to jumper preloader testpoint to the ground, just proceed to flashing
In this case I flash the unit with A850 firmware, but the results were totally dead, as in hindi na talaga nagbabasa sa PC, this solution might solve your problem
Let's begin!
Download this A850 stock ROM here ( MTK6582 )
Use this SP flash tool (SP_Flash_Tool_v5.1408.00), here
Open mo unit then hanapin mo ito, jumper into the ground
Unzip ROM file and start SP flash tools, Load scatter file > Download
Press down button and insert cable,wait until done
If in case invalid ang IMEI
Ito ang gagawin natin, para hindi na tayo mahirapan magrevive ng IMEI
Open CM2 MTK (6571...6595)
Insert bin download here
Remove jumper
Smile! Done!
Your lenovo A850 is now fully working again!
Smile!
