1. Readback method in SP Flash Tool has already failed as I first tried only that one. As I mentioned in my first post over here https://forum.hovatek.com/thread-10114.html
this phone was not letting me create a scatter file and a few found on the internet were didn't match to this phone when performing readback.
2. After being advised on that thread, I modified the ini file and once got able to create scatter file which created the file but in a format like not many scatter files usually created.(may be partition type difference or what I don't know) Any how, that scatter file was also not able to readback from the phone with a BROM error. I mentioned this over that thread.
3. Finally reached this thread of yours, when I was following some errors while trying to get root shell access after the iRoot(KingRoot) rooted this phone. Errors such "adbd file not found" - having them fixed all of them and having this phone rooted (with root shell), thanks to you.
Now stuck with this at Backup as the ZERO file issue persists in there. Wonder if we could try something else?
Anyway what other free BusyBox on playstore? can you provide specific links please?
Also, if you could advise, how to select options in SP Flash Tool for this scatter file (attached)? They way I tried, failed.
Do you think the content of the files generated (even though partially with error) with Backup process in MTK Droid Tools can give some idea of the issue?
