How to fix MultiTask Crash / Respring on 4.2.1 iPhone 3G

blog info BY   blog info 88 COMMENTS   blog info Random

Download this file and drop it inside “/system/library/coreservices/”. (Using DISKAID, or other device file browser, you can SSH too).

To do it manually, edit your N82AP.plist and change “<key>opengles-1</key>” to “<key>opengles-2</key>”.

Reboot your device or respring.

The above .plist, enables multitask and fixes the crash, but if you are searching for Multitasking + HomeScreenWallPaper + Fix: Download This .Plist and drop on the same place mentioned above.

I don’t know if more people found this before, I fixed accidentally messing with the plist to enable multitasking. It crashed a lot and I started to change every value to find what I broke.

      Install iFile from Cydia and go to /System/CoreServices/ and find the N82AP.plist and you can veiw and edit it from there directly on your iphone with out a computer and it should work

    Alternative to the above fix that does not give the graphic errors i.e. sms send button etc*Taking some help I got in another thread on ipt forums, I decided to make it into a tutorial since lots of people think this would be useful.As we all know, apple decided it would be cool to break support for pro switcher, multifl0w, etc and use their crappy multitasking instead. In this tutorial, I will explain how to use Apple's multitasking bar with Backgrounder. Note this disables Apple's 'multitasking' and replaces them with backgrounder multitasking.This is great for older iDevices with 128MB RAM because they don't support Apple's multitasking anyway, but these steps can be performed on any iDevice.Here are the steps:1. Jailbreak your iDevice (duh )2. Open Cydia and download Backgrounder3. Open Backgrounder and go to Global. Make sure "Backgrounder" is checked as 'Backgrounding Method' and "Fall Back to Native" is TURNED OFF4. SSH TO /System/Libary/CoreServices/SpringBoard.app5. Locate the N72AP.plist6. Copy the .plist file to your computer. Open your .plist editor program and add the following (anywhere in the file):mulitasking7. Copy the newly edited .plist file back to the directory on your iDevice and REBOOT.8. Open Cydia and download a package called Remove Recents.9. Respring and you're done!!***PLIST EDITOR:***[/b]STEPS 4-7 ARE NOT REQUIRED FOR iPod Touch 3G, iPhone 3GS, and iPhone 4

    Sorry it should be N82AP.plist you need to edit.

    Also if you have used the above fix change opengles-2 back to opengles-1

    Bug fix for springboard crash when sending messages from contacts; tethering and reading msgs while in an open application - Czar style... :pfor jailbreak 4.2.1 redsnow :)Steps:1. download and install iFile from cydia2. open iFile3. SSH to /System/Library/CoreServices/SpringBoard.app4. scroll down, find and edit N82AP.plist5. Locate and edit this command inside the program list, simply replace the the "true" text to "false" to disable the program. (do not remove less than and more than sign before and after /false)multitasking to: multitasking /true /false6. save the N82AP.plist and exit iFile7. respring and your done... no more springboard not saying that this will work in all phones, but this works for me so im just sharing it to y'all.

    Hey Friends,I have 3G and recently updated with 4.2.1. After that i was facing the problem, like SMS app get crashed while replying to any text, or sending text from recent calls,I solved the same, with mentioned tutorial, making False to Multitasking, in .plist file. and it works, Gr8.But is there, any way, where i can use both multitasking and SMS Reply, from contact and from recent as well. becuase multitasking helps me to navigate easily, while without that, WhatsApp, and other related application does not work, each time i open that appication, and it goes to connect.Please help me to sort out. Would be greate tutorial.Thanks hardik.
