Jailbroken iPhone: iMessages?

I recently Jailbroke my iPhone 5 running ios8. It was working fine until I downloaded the text message customizer. When I try to open iMessage it turns white and returns to home page.

How do I fix this?

Just go into Cydia and remove the message customizer. This means that it is not supporting ios 8 yet. And therefore you can't use it.

  • Why is my Iphone not sending as Imessages and receiving iMessages from one person? I'm texting my wife and we both have iPhone's and she is getting the messages as an iMessage but the ones I'm sending her on my end show up at green. Sometime it will go as blue, get the little red exclamation point then send as regular SMS. I'm texting someone else too and she has an iPhone, and she is getting mine as regular iMessages and mine are sending as regular iMessages. Why aren't they sending to me wife as iMessages?

  • My iPhone and iPod randomly stopped sending iMessages It was working, then all of a sudden, the messages stopped sending! I turned iMessages off in settings, then re-turned it back on, and came up with some stuff about re-entering my Apple ID password, which it never has done before. And now, when I text people who have iPhones, it sends normal texts. I'm in the UK, anyone else with this problem! It's also saying it can't verify my Apple ID, and I haven't changed any of it, and it is still not sending iMessages.
  • My iMessages on Iphone 4s is not working Ok so I went on setting and put imessages on. I'm texting my boyfriend (who has an Iphone 4) and the text bubbles are not blue they are still green. Does the fact that my iphone is upgraded to ios 5.1.1 is the problem? Or is it something else?
