Hello Forum Im in desperate need of some help for a person with some higher understanding of iphones. I brought a iphone 4 AT&T locked. This iphone version was 4.0.1 now I did some research on jailbreaking thought it was pretty straightforward and jailbroke it using jailbreakme.com then carrier unlocked it using ultrasnow. No problems at all working perfectly , I installed this appiclation Vwallpaper and downloaded some video wallpapers , no problem at all , until ! I downloaded the video wallpaper of assassin's creed video wallpaper , so I downloaded installed it and once I did the iphone crashed . I rebooted and started up got to the lock screen , now EVERY single time straight after I open the slider to get into the phone the phone crashes, Every single time ,only thing you see is a black screen the icons like normal but its crashed everytime , without fail its like a semi-brick , had the phone one day only . I have been researching on fixes for days now , iam going crazy I spent a huge amount of money on this phone and nothing . I have Tried the following methods on trying to fix it AND NOTHING! Hard Reset (Hold down the home button and power button for 10secs) I cant restore 4.0.1 on itself because the signatures are not on the apple server for 4.0.1 I have tried to uninstall vwallpaper using the program cyder 2 I do not have SBS settings so I can not enter into safe mode I have tried the Tiny umbrella program to emulate SHSH blobs on the server Do not have Open SHH installed So my question is, if I dont have the option of Open SHH and no option of going into safe mode to disenable Vwallpaper or springboard . Yes I had springboard installed and I have summed it down to one of those to programs, could be something else tho , thats why I m here. So the only option I have in my head right now is the following Restore and upgrade using itunes 10 so , upgrade to 4.02 then downgrade to 4.0.1 now not sure if I should do this , since my iphone is currently jailbroken and if I update to 4.0.2 it will get automatically bricked right therefore giving me no chance to downgrade , not sure about this part. This is the only thing I found on it http://www.redmondpie.com/downgrade....0.2-to-4.0.1-without-shsh-blobs-saved-guide/ I saw thread in this forum with a problem very similar or the same here is the link http://forums.macrumors.com/showthread.php?t=1008201 Thank you for taking the time to read this I will enduringly grateful to who ever figures out a fix for this weird crash loop (after lockscreen) I will be giving a reward(No joke, Cash via paypal) to who ever figures it out, Thank you for your time.
