          • Sumit

            Of-course they help..but act like you don’t know what happen…don’t tell them you formatted the NVRAM.

    Why Lenovo Mobile company not help owner of Leno k 4 note downgrade marshmallow version into lollipop version
    Please help.

    • Company provide support by opening service center..they downgrade your phone for free of cost (If its in warranty)

      • Hey Sumit,

        Company doesn’t provide warranty for downgrade facility. I myself is victim of that and now I am downloading files given by you and will try this.

      • What a way to get help please, in exchange lenovo A7010 and is in the guarantor

  3. Marshmallow Bakvaas he lollipop mast me kya karu mujhe fir se lollipop cahiye…..

  4. Me apne mobile lenovo k4 note Downgrade kaise karu please help….

  5. hello, i have manually updated k4 not from S200_160309_ROW….it is very worse, how my old lollipop is S152_160302_ROW. help me to get back to my this version…i am all new to this..so guide m plz

  6. I cannot get a clear idea from the above matter given.so can you plz make a video and place it.

    • Actually, I don’t have the device for now so not able to make a video but the steps are very clear just follow from step 1 it will work. And if you have any confusion about any of the step ask here we are happy to help you.

  7. and tell me, while downgrading, phone will become dead or brick…..how much risk if i follow step wise as you told…??

    • There is always a small risk you have to take but the process above is safe and many users already flash the stock ROM with above and no one reported any bricking issue.

  8. i purchased phone about a month back, so it in warranty. Should I use the above process or give to service station.
    PS: Nagpur city don’t have any service station for mobile, so is it safe to give to other mobile repair centre?
    Thank you sir.

    • Above process is safe to follow but if you want to give to service center make sure they are authorized by Lenovo and cover your warranty.

  9. Connect USB cable means I have to connect for laptop or just keep charging

    • Connect to Laptop via USB cable and make sure your device recognized by SP Flash Tool

  10. If i downgrade it will i be able to get my data back. As when i upgraded the device i am not able open my contacts,call logs it keeps on loading. My contact list is the most important thing for me at this point.

    • Don’t you save the backup of your contact on Google? If you downgrade all your data will wipe.
