]Hi, I've a problem with the repacked update.img to use with RockChip Create Upgrade Disk Tool v1.43

First I did this to unpack it, it was the only way with these extra commands.

C:\imgRePackerRK_104>imgRePackerRK.exe /cid /skip update.img

imgRePackerRK (version 1.04 windows)
Rockchip firmware batch image unpacker/packer

==========================[ STOP ]==========================

Then I replaced ''RK3168Loader(L)_V1.26.bin'' with ''SDBoot_V1.17.bin'' in /update.img.dump\Image and edited ''package-file'' to rename the bootloader, after that I copied ''parameter'' from \Image to /update.img.dump or else I could'nt repack the update.img

After that I did:

C:\imgRePackerRK_104>imgRePackerRK.exe /rkaf /2nd /ini update.img.dump

Now the problem comes when I run RockChip Create Upgrade Disk Tool v1.43 and import the new repacked update.img it says '''Opening firmware failed!'

How can I fix this issue please, or what I'm doing wrong?
