How do I stop OTA update once started?

[Alphos2000]

I have an iPad 2 with IOS 5.0.1 jailbreak and today I noticed the iOS 5.1 upgrade. Trying to remove the red balloon on settings icon, I accepted the update and now everytime I connect the iPad to Wifi is keeps downloading the update. I don't find option to cancel it.

I tried to install a plug-in cydia called "No update", but no use. I think it is to avoid giving the download button, but as I have already done it ...

Do you know if I have to finish downloading the option to cancel, refuse or stop OTA installation?

Is there any way "manual" to stop it?

I did that too only way I got it off was a restore.

I had a similiar situation. I decided to jailbreak my iPad2 the day after the 5.1 update came out. When I turned on the iPad, it started downloading the 5.1 update. I quickly did the Absinthe jailbreak and installed NoUpdate from Cydia before the 5.1 download finished. I then checked in Settings-Update and the file was still downloading. I thought I was too late and would be forced to update to 5.1 After a reboot that changed nothing on the download of 5.1, I resigned myself to being upgraded. However, after the download finished, and before the install started, NoUpdate kicked in and I was NOT upgraded to 5.1!

So, I think if you have NoUpdate installed and the update is still downloading, you will not be upgraded to 5.1. Miight still upgrade you but it did not upgrade me. Also, I have the red 1 on the settings icon showing there is an update available, but when I check Settings-Update, NoUpdate kicks in and I am still safe.

My advice is to just let it run and see how it goes.

Finally I managed to stop it.

Somewhere I found how to stop Daemons or process started at boot. It is possible to stop some of them if you have your device jailbreaked. I stopped all process related to OTA and now NoUpdate works correctly and OTA will never work again unless I activate them again

The only thing I don't know is where is located the temp download file of the new firmware. Probably it's taking 200-300MB from my ipad unless I delete it...

@jefferyan88, there is a Cydia plugin that will delete the red 1 on the settings icon called noOTA Badge, maybe you are interested on it

@Alphos2000 I will check it out. Thanks

If you are jailbroken then you can't upgrade OTA, even if it tries to download the firmware. The OTA updater checks the hashes on the Applications directory and since you're jailbroken they don't match, so it doesn't allow you to update
