Help/Support save game cheats problem

[datagen 598 iPad Air 2 11.3.1]

I'm using the latest method and have been stuck on it for about 2 days now. 1st question, in teds video how did he open the .imazing file with WinRAR. When I try to do it I don't get an option to open it with Winrar I have to go to winrar manually and open it.

2nd question, I think this may be the reason it hasn't been working. When restoring app with new hacked files it reboots once and then it makes that sound after rebooting as if my iPad was unplugged from the laptop and then reboots again and makes the sound as if I plugged it back into the computer. funny that it basically rebooted 2 times. Another weird thing is that after 2nd reboot I get a new icloud terms and conditions thing that pops up and after I enter the password it said update completed as if I just updated to a new ios..? Wtf is this I then go back to kick the buddy and see the same 215 cash as I saw before I changed the files. I CHANGED THE FILES aren't I suppose to have at least 100 million coins? I changed the files. I'm thinking that this 2nd reboot thing has to do with it. Maybe the 1st one failed and then rebooted back to my normal data with the 2nd reboot. I do not know. Im seriously upset and pissed about this. The old method I mastered the first day with ifunbox. I Don't know but I really want to get this over with and learn how to do this. My birthday is today as I'm posting this at 12:31 and I would really like to learn this today.

Have any questions I will answer them.
