Recently i got a notification on my Lenovo a536 saying system update(VIBE official update) is available. So as usual i kept for update, the update package was downloaded and phone booted into startup and started upgrading. Suddenly the upgrade got stuck and it was showing only one thing "No Command" on the screen with a Android Bot image. Without knowing what it was, i formatted the phone from startup menu. Later i came to know, my phone is dead. So i had to flash it with stock ROM again. I was not able to flash it with any ROM because my device was not rooted. So here is how i did it finally.
Requirements:
Lenovo a536 Stock ROM
USB VCOM Driver
SP Flash Tool
So once you've downloaded all the files, follow the below steps. Remember to charge your phone to 30-60 Mins before you start.
Step 1: Unzipping
Unzip all the downloaded files and keep it in different folders.
Step 2: Install the drivers
**This is a very important step. If the drivers are not up to date, nothing is gonna work**
Open the Device Manager in your PC.(Can be opened by typing Device Manager in start menu). Remove your phone battery, connect the phone to your PC/Laptop via USB cable. Make sure you use a good quality cable and the powerful port of your PC. Once you connect, your Device Manager will show up the connected device as Mediatek Preloader device.
Right click on it and click update driver. Click Browse Computer and navigate to the USB VCOM unzipped folder.(The device may flash on the list for seconds and vanish and again appear. So right click on the device before it disappears.)
Step 2: Flash the ROM
Once you install the Driver, next you can Flash the device.
Remove the connection and put the battery back. Do not switch on the device.
Open SP Flash Tool provided with the ROM package.(flash_tool.exe)
First Go to Options>>Options>>Download>>Check the box DA DL All with checksum.
Click on Scatter Loading and Choose the file MT6582_Android_scatter.txt in target_bin folder in the extracted file. I will add all the images to flash.
Change the Download only option to Firmware upgrade. and click on Download.
Now the Flash Tool will wait foe the device to connect. Now connect your device using USB cable with battery in but without switching on the phone. Download process will start.
Once it finishes you'll get a success screen as below.
That's it. You have successfully flashed your phone. Now you can Reboot your phone. It'll be same like before. You will be recieving the updates and once you update the system normally. Everything will be normal.
Possible Errors
Your Download process may get stopped due to many type of errors and many number of times. Still do not give up. If you're continuously getting error and the download process stops, try downloading without battery. (Remove the battery and connect the device with USB cable, during the above process.)
