If any of you are stuck with the 7Day Cert from Saurik's tools - you can get your 1 year cert back by following this method which does NOT require an AppleID and does NOT require you to restore and reJailbreak... Just follow these steps.
--------------------------
First of all, this method doesn't require you to update your iDevice to delete the jailbreak and it doesn't require your apple ID
Thanks to /r/Toby4ever for sharing the link to the chines tutorial
So here are the steps.....
• Delete your signed jailbreak app ( which you signed with 7 days cert.).
• Reboot your device
• Activate Airplane mode and keep the WiFi off.
• Download a fresh copy of inv_ent_final_0727.ipa from here-->
http://download.25pp.com/ipa/jailbreak/inv_ent_final_0727.ipa
• Open any iDevice manegment like iTools or iFunBox or IPAInstaller-Windows
• Go to application management and install the application (inv_ent_final_0727.ipa) into your device
• On your iDevice and disable airplane mode
• Go to Settings -> General -> Device Management and accept/trust the cert
• Open the jailbreak app ( I myself dont link 25pp application because it hooks into your springboard for no reason so when you jailbreak the first time, uncheck the box like in the picture ).
and thats it. hope it would help.
PS: I did the above 4 times on my iDevices and it works every single time.
EDIT: If you already have PP store installed on your device, you can delete it from cydia.
EDIT2: There is no need to use pp Helper to install the app, we have a new method ! in ENGLISH
EDIT3: Added IPAInstaller-Windows tool to install the ipa without installing anything on your PC, thanks to /r/S4109.
