First of all you need to know whats version do you have in your device. After that watch some guide videos on you tube. Do not watch old videos because it wont be helpful or probably it's blocked.
If you 5.0.1 above you can easily go to Google type in that red snow download than download the newest version because it will be a lot easier to solve your problem. After you download it just click on it open it up and just click on jail breaking and do not select any other options because it will not work. Then you do it follow the instruction hold your power button for about 10 seconds then home button then release the power button. while you doing this method if apple sign goes away, unplug the device. Also Keep following rules i mean holding button stuff until your device get back on turn off mode. Then turn on the iPhone i'm 100% sure it will work and will not stuck on apple sign. Thanks i hope it will be helpful.

The App Store should already come with your iDevice. If it doesn't contact Apple Support or go back to the place you purchased and inquire the features of your iPhone. If the icon is not there maybe there is an Restriction on your iPhone. To turn it off just go to Settings > General > Restrictions >Turn off. And the App Store should appear on your home screen.
