Final thoughts

It is completely normal. Also, the mods or hacks you apply through ADB may not stick if you restart your device. That is one of the disadvantages of this method. But if you do not restart your device quite often, you should be good. Also, if restart your device, you can simply execute the command in the 8th point in the guide to re-apply the mod.
