How to use Research Download tool to backup Unisoc / Spreadtrum firmware

[@FLomasterZ]

Spreadtrum have uart? Is it possible to write/read flash from that bus?

[@wesleystoffels9807]

Hi i see your nvitem is also 2,048kb, and writing that to your flash will give you a partition is oversized error. I had to use hex editor and remove all unnecessary parts that the tool created to get it below 1,500kb thats the only way the tool will accept that file. I successfully flashed no network phone with the nvitem back and it brough back the signal. I am now struggling with the exact same phone(nvitem from previous phones back up they are the same but still not getting signal on the second phone). Can you perhaps assist?
