Just because you can't follow instructional videos that shows you how to do what you're looking to do, or, research on what you're looking to do, you blame me for not resolving your issue. There's no point in jailbreaking a device if you don't understand what the underlying importance of a jailbreak is. Even if you're flashed to Cricket, there are maintenances that you have to periodically perform to keep the Cricket APN and carrier changes up to date. If flashing to Cricket is too difficult of a task, then you may as well just buy a new device or another 4 with a clean ESN/IMEI rather than buying one that was labelled with a bad ESN.
Flashing to Cricket is not a simple task. Knowingly, if you bought a device with a bad ESN, you were well aware in advance that your device will be a problem when you want to update the device and you will have issues when Crickets starts updating their APNs and carrier settings. You bought the device knowing that it's running Cricket, and that it has a bad ESN. You should've done the research prior to purchasing the device so that you know EXACTLY what you're dealing with, and not just buying it because it was cheap. If it's cheaper than the average market value, there's clearly something wrong with it and will require attention over an extended period of time.
Considering this thread is going nowhere, there's no sense in discussing about how not to do a bit of research and looking for the easy way out. This thread is now closed.
