[Tutorial] How to use Research Download tool to backup Unisoc (Spreadtrum) firmware

Your backup nvtem.bin contains more 0000000000, so it is larger in size. In HexEditor edit your backup nvtem.bin so it ends in the same way as the nvtemb.bin from stockrom, namely trim unnecessary 00000000 to reduce the size and then save. I did so and my edited backup nvtem.bin flashed with Research Download without previous error IMG SIZE OVER ITS PARTITION.At 2:15 of this video https://youtu.be/M_hHEMo158U, a guy fills in the contents of the "Active read Flash" with the values of the "Base1" and "Size1" columns from the UpgradeDownload tool. I tested this for a partition that was in error and it works. However, I did not go any further.
